The above structure will be introduced in detail below.

First, the busbar plug-in structure in the power distribution system is introduced to facilitate understanding of the plug-in method of the busbar duct 1 and the plug connector 32 of the plug-in box 3. Both the bus duct 1 and the plug-in box 3 have plug-in sides, wherein the plug-in box 3 has a first plug-in side and the bus duct 1 has a second plug-in side.

As shown in FIG. 1 , the busbar plug-in structure includes a busbar duct 1 , where the busbar duct 1 includes a housing 11 , an insulating bracket 12 and a conductive plate 13 . The housing 11 has a rectangular box-shaped structure, one side along the length direction is the second plug-in side, and the plug connector 32 is plugged into the bus duct 1 on the second plug-in side. The housing 11 has a plug-in slot 111, which is distributed along the length direction of the case 11, and the slot of the plug-in slot 111 is located on the second plug side.

The insulating bracket 12 is elongated and is located at one wall of the plug-in slot 111 along the length direction of the plug-in slot 111 . As shown in FIG. 2 and with reference to FIG. 1 , the conductive plate 13 is also in the shape of a long strip and is located in the insulating bracket 12 . The insulating bracket 12 half wraps the conductive plate 13 so that the conductive plate 13 has a first portion exposed in the plug slot 111 . Electrical connection surface 131.

As shown in Figure 3, the busbar plug-in structure also includes a plug connector 32. The plug connector 32 includes an insulating piece 321 and a power-taking blade 322. The power-taking blade 322 is located on one side of the insulating piece 321. The power-taking blade 322 There is a second power connection surface 3222. Specifically, the power extraction blade 322 has a power connection portion 3221 that protrudes away from the insulating member 321 , and the power connection portion 3221 has a second power connection surface 3222 .

As shown in Figures 2 and 3, when the plug connector 32 needs to be inserted into the bus duct 1, the plug connector 32 is inserted into the plug slot 111 of the bus duct 1 on the second plug side of the bus duct 1, and the busbar The first electrical connection surface 131 of the slot 1 is in surface contact with the second electrical connection surface 3222 of the plug connector 32 . Once the first power connection surface 131 and the second power connection surface 3222 are in contact, the plug connector 32 and the busbar duct 1 can be connected to each other.

As shown in FIG. 3 , the plug connector 32 includes a plurality of plugs 320 , and each plug 320 includes the above-mentioned insulating member 321 and a power extraction blade 322 . Among them, the number of plugs 320 is the same as the number of plug-in slots 111 of bus duct 1. For example, the number of plug-in slots 111 is three, then the number of plugs 320 is also three, and the plug-in slots 111 and plugs 320 are one by one. correspond.

For example, Insert the plugs 320 of the plug connector 32 into the plug slots 111 of the bus duct 1 one by one.

The above is an introduction to the busbar plug-in structure of the power distribution system. The specific structure of the busbar duct 1, connector 2 and plug-in box 3 will be introduced in detail below, as well as the connection relationship between them.

(1) Bus duct.

As shown in Figure 1 and with reference to Figure 2, a schematic structural diagram of the bus duct is shown. The bus duct can be a small bus duct, which is a bus duct that transmits a current within 800A. Of course, the bus duct may also be a large bus duct, and the embodiment of the present disclosure does not limit the specific type of the bus duct.

As shown in Figure 1 and with reference to Figure 2, the bus duct includes a housing 11 and a conductive plate 13. The housing 11 has a plurality of plug-in slots 111 distributed along the length direction, and the slots of the plurality of plug-in slots 111 are located at same side of housing 11. The housing 11 has a rectangular box-shaped structure, and one side along the length direction is the second plug side. As shown in Figure 4 and with reference to Figure 1, the housing 11 has a plurality of plug-in slots 111. Each plug-in slot 111 is distributed along the length direction of the housing 11, and the slot of the plug-in slot 111 is located at the second plug-in socket. side. Among them, the plug-in slot 111 is used for inserting the plug connector 32 of the plug-in box 3 .

The conductive plate 13 is located in the plug-in slot 111 and is insulated from the housing 11 . The conductive plate 13 has a first electrical connection surface 131 exposed in the plug-in slot 111 .

The bus duct 1 also includes a plurality of insulating brackets 12, as shown in Figure 2 and with reference to Figures 1 and 5. The insulating brackets 12 are located in the plug-in slot 111. The insulating bracket 12 is in a long strip shape and extends along the length of the plug-in slot 111. The direction is located at one slot wall of the plug slot 111.

Among them, the insulating bracket 12 is used to support the conductive plate 13.

In one example, regarding the structure of the insulating bracket 12, please refer to FIG. 6 and refer to FIG. 1. The insulating bracket 12 has a through groove 121 along the length direction, and the through groove 121 has two notches. respectively located at both ends along the length direction of the insulating bracket 12 . Generally, the length of the conductive plate 13 is greater than the length of the insulating bracket 12. In this way, the conductive plate 13 is inserted into the insulating bracket 12 from one slot of the insulating bracket 12 and extends from the other slot.

As shown in FIG. 6 and with reference to FIG. 1 , a slot wall 122 is provided in one groove wall of the through slot 121 of the insulating bracket 12 . The notch 122 is used to expose the conductive plate 13 supported by the insulating bracket 12 . As shown in FIG. 6 , the notch 122 divides the groove wall of the through groove 121 into an upper groove wall 124 and a lower groove wall 123 . Among them, the upper groove wall 124 is the groove wall of the through groove 121 used to form the gap 122 and is located away from the slot opening of the plug-in slot 111, and the lower groove wall 123 is the groove wall of the through groove 121 used to form the notch 122 and is located close to the slot opening of the plug-in slot 111 .

In this way, the upper groove wall 124 , the lower groove wall 123 and other groove walls of the through groove 121 form a receiving space for the conductive plate 13 , and there is no groove wall blocking the gap 122 , so that the conductive plate 13 is exposed in the plug-in slot 111 , as shown in FIG. 7 shown.

When the insulating bracket 12 is inserted into the plug-in slot 111 , the insulating bracket 12 is located at one slot wall of the plug-in slot 111 , and its notch 122 faces the other opposite slot wall of the plug-in slot 111 . For example, the insulating bracket 12 is located at the first slot wall of the plug-in slot 111, the notch 122 of the insulating bracket 12 faces the second slot wall of the plug-in slot 111, and the positions of the first slot wall and the second slot wall of the slot 111 are Directly opposite.

In one example, the insulating bracket 12 is locked in the plug-in slot 111 by snapping, as shown in FIG. 5 for details.

As mentioned above, the insulating bracket 12 is used to support the conductive plate 13. Then, as shown in Figure 2 and with reference to Figures 1 and 7, the conductive plate 13 is also in the shape of a long strip and is located in the insulating bracket 12, and the insulating bracket 12 is half The conductive plate 13 is wrapped so that the conductive plate 13 has a first electrical connection surface 131 exposed in the plug slot 111 . For example, the conductive plate 13 located in the insulating bracket 12 exposes the first electrical connection surface 131 through the notch 122 of the insulating bracket 12 , so that the first electrical connection surface 131 is exposed in the plug-in slot 111 to connect with the third plug-in box 3 . The two electrical connections 3222 are in contact and conductive.

Among them, the conductive plate 13 can be a copper plate, used for transmitting power, and one conductive plate 13 corresponds to one phase line. For example, for a three-phase five-wire power distribution system, the number of conductive plates 13 is five, corresponding to three phase wires, one neutral wire and one ground wire respectively. For another example, for a three-phase four-wire power distribution system, the number of conductive plates 13 is four, corresponding to three phase wires and one neutral wire, or three phase wires and one ground wire.

In an example, as shown in FIG. 6 , the plurality of plug-in slots 111 may include at least one first plug-in slot 111A. Two insulating brackets 12 are installed in the first plug-in slot 111A, and the two insulating brackets 12 are installed in the first plug-in slot 111A. The brackets 12 are located at two opposite slot walls of the plug-in slot 111. Each insulating bracket 12 is installed with a conductive plate 13, and is located on the first contact surface 131 of the two conductive plates 13 in the same plug-in slot 111. are positioned relative to each other, with a gap between them.

For example, for a bus duct including an even number of conductive plates 13, all the plug-in slots 111 may be the first plug-in slots 111A.

Specifically, for a three-phase four-wire bus duct, the number of conductive plates 13 is four. Then, the bus duct may include two plug-in slots 111, and both of these two plug-in slots 111 are first plug-in slots. 111A, each first plug slot 111A is equipped with two insulating brackets 12, and each insulating bracket 12 is installed with a conductive plate. 13, in this way, the four conductive plates 13 can be located in the two plug-in slots 111, realizing one slot and two poles.

For another example, for a bus duct including an odd number of conductive plates 13, the plurality of plug-in slots 111 may include first plug-in slots 111A and second plug-in slots 111B. For example, the number of second plug-in slots 111B is One, and the rest are first plug slots 111A. Among them, the insulating bracket 12 and the conductive plate 13 installed in the first plug slot 111A can be referred to the above description. An insulating bracket 12 is installed in the second plug-in slot 111B, and the insulating bracket 12 is located at one slot wall of the second plug-in slot 111B, and the notch 122 of the insulating bracket 12 faces the other slot wall of the second plug-in slot 111B. The conductive plate 13 is installed in the insulating bracket 12, and there is a gap between the first conductive surface 131 of the conductive plate 13 and the other groove wall of the second plug slot 111B. For example, the insulating bracket 12 is located at the first slot wall of the second plug-in slot 111B. The notch 122 of the insulating bracket 12 faces the second slot wall of the second plug-in slot 111B. There is a distance between the power connection surface 131 and the second groove wall, where the first groove wall and the second groove wall are positioned opposite to each other.

Specifically, for a three-phase five-wire bus duct, the number of conductive plates 13 is five, so the bus duct may include three plug-in slots 111, and the three plug-in slots 111 include two first plug-in slots 111. The first plug-in slot 111A is provided with two insulating brackets 12, and the second plug-in slot 111B is provided with one insulating bracket 12. A conductive plate 13 is installed in each insulating bracket 12 . In this way, part of the plug-in slot 111 can realize one slot and two poles.

In one example, when the number of the second plug-in slots 111B is one and the remaining ones are the second plug-in slots 111A, it does not matter which conductive plate 13 is located in the second plug-in slot 111B. For example, for a three-phase five-wire bus duct, the conductive plate 13 used for grounding can occupy a separate plug-in slot 111 (ie, the second plug-in slot 111B).

For example, the five conductive plates 13 correspond to phase A, phase B, phase C, phase N, and PE respectively. The N phase is the neutral line and PE is the ground wire. Phase A, phase B, phase C, and phase N can be corresponding to each other. The conductive plates 13 of PE are collectively called phase conductive plates and are marked with 13A. The conductive plates 13 corresponding to PE are called ground conductive plates and are marked with 13B. The insulating bracket used to support the phase pole conductive plate 13A can be recorded as the phase pole insulating bracket and marked with 12A. The insulating bracket used to support the ground pole conductive plate 13B can be marked as the ground pole insulating bracket and marked with 12B. Then, the ground electrode insulation bracket 12B can be installed in the second plug slot 111B, and the ground electrode conductive plate 13B is installed in the ground electrode insulation bracket 12B. You can refer to 7.

Of course, the conductive plates 13 corresponding to phase A, phase B, phase C and phase N can also be installed in the second plug-in slot 111B. This embodiment does not limit which conductive plate 13 is located in the second plug-in slot 111B. , an example can be taken where the ground conductive plate 13B is located in the second plug slot 111B.

Among them, the ordering relationship between the plurality of conductive plates 13, that is, the positional relationship between the plurality of conductive plates 13, depends on the line sequence relationship at the previous node of the bus duct. For example, if the line sequence of the previous node is PE, N phase, C phase, B phase and A phase, then, as shown in Figure 7, the multiple conductive plates in the bus duct are PE, N from left to right. Phase, C phase, B phase and A phase.

In an example, in order to avoid errors in the ordering of conductive plates in the bus duct assembly, correspondingly, as shown in Figure 7, the cross section of the ground conductive plate 13B is different from the cross section of the phase conductive plate 13A, then , the size of the through slot 121 of the ground electrode insulating bracket 12B is different from the size of the through slot 121 of the phase pole insulating bracket 12A, then the phase conductive plate 13 cannot be inserted into the ground electrode insulating bracket 12B, then, in this way, There will be no possibility of mistakenly inserting the phase conductive plate 13A into the ground insulating bracket 12B.

As shown in Figure 7, compared with the phase pole insulation bracket 12A, the ground electrode insulation bracket 12B has a square hole on the top to shorten the lateral length of the through slot 121. Moreover, the through slot of the ground electrode insulation bracket 12B The limiting protrusion on the groove wall of 121 is longer to shorten the lateral width of the through groove 121. In this way, the ground electrode insulation bracket 12B can be used to support the ground electrode conductive plate 13B with a smaller cross-section.

As mentioned above, as shown in Figure 7, there is a distance d1 between the first contact surfaces 131 of the two conductive plates 13 in the same plug-in slot 111. This distance d1 is used for the plug connectors of the plug-in box 3. 32 plug 320 is inserted, and the distance d1 is less than or equal to 12.5 mm to meet the IP2X standard to prevent technicians' hands from extending into the distance d1 and causing electric shock.

The above-mentioned distance d1 can be as small as possible to reduce the overall size of the bus duct under the condition that the plug 320 (such as the first plug 320A) of the plug connector 32 can be inserted.

For the case where there is only one conductive plate 13 in a plug-in slot 111, as shown in Figure 7, the distance d2 between the conductive plate 13 and the wall of the plug-in slot 111 can also be less than or equal to 12.5 mm. And if there is only one conductive plate 13 in a plug slot 111, and this conductive plate 13 corresponds to the ground wire, its current is zero, even if the technician puts his hand in, there will be no electric shock. Then, the conductive plate 13 and the plug The distance d2 between the groove walls of the groove 111 does not need to be limited.

The above-mentioned distance d1 can be as small as possible to reduce the overall size of the bus duct under the condition that the plug 320 (such as the second plug 320B) of the plug connector 32 can be inserted.

Such a bus duct in which two conductive plates 13 can be installed in one plug-in slot 111 can reduce its overall size, which is conducive to the miniaturization of the bus duct and reduces the space it occupies.

In one example, in order to improve the plug-in safety of the bus duct, correspondingly, as shown in Figure 7 and with reference to Figure 8, the outer end surface of the lower groove wall 123 of the phase pole insulation bracket 12A protrudes from the phase pole insulation bracket. 12A in The first electrical connection surface 131 of the phase conductive plate 13A.

In this way, when the plug connector 32 of the plug-in box 3 is inserted into the plug-in slot 111 of the busbar, when it is first inserted, the outer end surface of the lower slot wall 123 of the phase insulation bracket 12A protrudes from the phase conductive plate 13A. The first power connection surface 131, then, at this time, the second power connection surface 3222 of the plug-in box 3 is guided by the outer end surface of the lower groove wall 123 and cannot contact the first power connection surface 131. At this time, even if technically Even if a person's hand comes into contact with the power-taking blade 322 of the plug connector 32, no electric shock will occur. When the plug connector 32 continues to be inserted into the plug slot 111, the positions of the second power connection surface 3222 and the lower slot wall 123 are staggered. At this time, the first power connection surface 131 and the second power connection surface 3222 are in contact, but At this time, the ground conductive plate 13B has also been turned on, and the current will not flow to the technician, or the technician's hand can no longer touch the power-taking blade 322 of the plug connector 32 (obstructed by the safety plate 323, will be introduced below).

It can be seen that the outer end surface of the lower groove wall 123 of the phase insulation bracket 12A protrudes from the first electrical connection surface 131 of the phase conductive plate 13A in the phase insulation bracket 12A, which can improve the safety of the bus duct and reduce the number of technical personnel. Electric shock may occur during plugging.

In one example, if the ground conductive plates are not included in the plurality of conductive plates 13, for example, for a three-phase four-wire bus duct including A phase, B phase, C phase and N phase, then the bus duct does not include the ground conductive plate, then the outer end surfaces of the lower groove walls 123 of all insulating brackets 12 protrude from the first contact surface 131 of the phase conductive plate 13A in the phase insulating bracket 12A.

In other examples, if the plurality of conductive plates 13 includes a ground conductive plate, for example, for a three-phase five-wire bus duct, or for a three-phase four-wire system including phase A, phase B, phase C and PE. Customized bus duct. Then, the outer end surfaces of the lower groove walls 123 of all phase insulating brackets 12A protrude from the first contact surface 131 of the phase conductive plate 13A in the phase insulating bracket 12A, and the bottom of the ground insulating bracket 13B The outer end surface of the groove wall 123 is flush with or recessed from the first contact surface 131 of the ground conductive plate 13B in the ground insulation bracket 12B.

In this way, when the plug connector 32 of the plug-in box 3 is inserted into the plug-in slot 111 of the bus duct, the outer end surface of the lower slot wall 123 of the phase insulating bracket 12A protrudes from the first electrical connection of the phase conductive plate 13A. The outer end surface of the lower groove wall 123 of the ground insulation bracket 12B is flush with or recessed from the first contact surface 131 of the ground conductive plate 13B in the ground insulation bracket 12B. Then, the ground conductive plate 13B is connected to the plug connector 32 first, and the phase conductive plate 13A is delayed to be connected to the plug connector 32 . Once the ground conductive plate 13B is connected to the plug connector 32, the current can be directed to the earth through the ground conductive plate 13B, which is safe for technicians.

In one example, the outer end surface of the lower groove wall 123 of the phase insulating bracket 12A protrudes beyond the first power connection surface 131 of the phase conductive plate 13A. The outer end surface of the lower groove wall 123 is a slope, And points to the center of the plug slot 111.

In one example, the outer end surface of the lower groove wall 123 of the phase insulating bracket 12A protrudes from the first contact surface 131 of the phase conductive plate 13A. The entire outer end surface of the lower groove wall 123 may be a slope, or It may be that the lower groove wall 123 is flat at a position close to the notch of the plug-in slot 111 , and is an inclined plane at a position far from the notch of the plug-in slot 111 , as shown in FIGS. 7 and 8 .

In one example, the plug-in slot 111 of the bus duct can adapt to the conductive plates 13 of different cross-sectional sizes. When the current transported by the bus duct is relatively large, the cross-section of the conductive plate 13 is relatively large, and the plug-in slot of the bus duct is A conductive plate 13 with a large cross-section can be installed in the slot 111. When the current transported by the bus duct is small, the cross-section of the conductive plate 13 is relatively small. A conductive plate 13 with a small cross-section can be installed in the plug-in slot 111 of the bus duct. . It can be seen that the bus duct can accommodate conductive plates 13 of various sizes.

Wherein, if the cross-section of the conductive plate 13 is different, the cross-section of the through-slot 121 of the insulating bracket 12 is also different. The cross-section of the through-slot 121 of the insulating bracket 12 matches the cross-section of the conductive plate 13 .

Normally, when the bus duct is in use, the size of the phase conductive plate 13A will not change, but the size of the ground conductive plate 13B will change depending on whether it is direct current or alternating current. Then, correspondingly, use The insertion slot 111 for installing the ground electrode conductive plate 13B can adapt to various cross-sectional sizes of the ground electrode conductive plate 13B.

For example, the ground electrode conductive plate 13B may include a variety of ground electrode conductive plates with different cross-sectional dimensions, and the ground electrode insulating bracket 12B may include a variety of ground electrode insulating brackets 12B. The cross-sectional dimensions of the grooves 121 are different, and the ground conductive plate 13B of one cross-sectional size corresponds to the through-groove 121 of one cross-sectional size.

In one application, when the bus duct provides alternating current to users, phase A and phase N form one circuit, phase B and phase N form one circuit, phase C and phase N form one circuit, a total of three circuits, which are enough for users to use. In this case , the cross-section of the ground conductive plate matches the cross-sectional size of a phase conductive plate, for example, the cross-section of the ground conductive plate is half of the cross-section of the phase conductive plate.

When the bus duct provides direct current to users, phase A and phase B need to be combined as the positive pole, and phase C and phase N must be combined as the negative pole to be sufficient for the user. In this case, the cross section of the ground conductive plate and the two The cross-sectional dimensions of the phase conductive plates match. For example, the cross section of the ground conductive plate is half of the cross section of the two phase conductive plates. Then, the cross section of the ground conductive plate is the same as that of one phase conductive plate. The cross-sections of the plates are the same. It can be seen that compared with providing alternating current, when providing direct current, the cross-section of the ground conductive plate is larger. At this time, the ground electrode insulation bracket with a smaller cross-sectional size of the through slot 121 can be replaced with a ground electrode insulation bracket with a larger cross-section of the through slot 121 to facilitate the installation of the ground electrode conductive plate with a larger cross-section.

For example, when the bus duct transmits alternating current, the cross section of the ground conductive plate 13B is a small cross section as shown in Figure 7, and the cross section of the through slot 121 of the ground insulation bracket 12B is a small cross section as shown in Figure 7. When the bus duct transmits DC power, the ground conductive plate 13B can be replaced with a conductive plate the size of a phase conductive plate as shown in Figure 7, and the ground insulation bracket 12B can be replaced with a phase insulation bracket as shown in Figure 7. size insulating bracket.

This kind of plug-in slot 111 can adapt to conductive plates 13 of different cross-sectional sizes, which can reduce the processing of the housing 11. There is no need to process more housings 11 to adapt to conductive plates 13 of different sizes, thereby saving money on processing the housing. The mold investment of body 11 is reduced to save processing costs.

Moreover, since the second plug-in slot 111B can adapt to the ground conductive plates 13B of different cross-sectional sizes, so that the bus duct can be used for AC and DC, there is no need to process a bus duct for transmitting AC and a bus duct for transmitting DC. Another bus duct, which in turn can save processing costs.

As an example, as shown in Figure 3, in this embodiment, the plug connector 32 includes an insulating piece 321 and a power-taking blade 322. The power-taking blade 322 is located on one side of the insulating piece 321. The power-taking blade 322 has The second electrical connection surface 3222.

Figure 9 is a schematic diagram of the plugging between the bus duct 1 and the plug connector 32. With reference to Figure 9, in this embodiment, the plug connector 32 is inserted into the plug slot 111 on the second plug side, and the first electrical connection surface 131 is in elastic electrical contact with the second electrical connection surface 3222.

The second plug-in side of the housing 11 has a plug-in slot 111 for accommodating the conductive plate 13 and providing a mounting base for the conductive plate 13 . The conductive plate 13 is installed in the plug slot 111. The conductive plate 13 is insulated from the housing 11 to ensure the safety of electricity. The conductive plate 13 has a first electrical connection surface 131, and the first electrical connection surface 131 is exposed to the plug socket. In slot 111. The plug connector 32 includes an insulating member 321 and a power-taking plug-in piece 322. The insulating piece 321 is used to provide a mounting base for the power-taking plug-in piece 322. The power plug 322 has a second power connection surface 3222. After the plug connector 32 is inserted into the plug slot 111, the first power connection surface 131 on the conductive plate 13 contacts the second power connection surface 3222 on the power extraction blade 322, thus realizing the connection between the bus duct 1 and the plug connector 32. electrical connection between them.

Moreover, since the conductive plate 13 and the power-taking blade 322 are in surface contact through the first power connection surface 131 and the second power connection surface 3222, the insertion stability between the busbar duct 1 and the plug connector 32 can be improved.

In one application, the side of the bus duct 1 facing away from the second plug side is the installation side, and the side of the bus duct 1 is The installation side can be installed on the top of the IDC machine room. The plug-in slot 111 of the bus duct 1 faces the ground of the IDC machine room. The technician can hold the plug-in box and insert the plug connector 32 of the plug-in box into the bus duct 1. For example, The plugs 320 of the plug connector 32 are inserted into the plug slots 111 of the bus duct 1 one by one, so that the plug box can take power in the bus duct 1 .

In this embodiment, the bus duct 1 may be a small bus duct 1. The small bus duct 1 is also a bus duct 1 that transmits a current within 800A. Of course, the bus duct 1 may also be a large bus duct 1. The embodiment of the present disclosure does not limit the specific type of the bus duct 1.

In this embodiment, the housing 11 has a plurality of plug-in slots 111 distributed along the length direction, and each plug-in slot 111 has a conductive plate 13 inside. The plug connector 32 includes a plurality of plugs 320 , and each plug 320 includes an insulating member 321 and a power extraction blade 322 .

Illustratively, the number of plugs 320 is the same as the number of plug-in slots 111 of the bus duct 1. For example, the number of plug-in slots 111 is three, then the number of plugs 320 is also three. The plug-in slots 111 and the plugs 320 One-to-one correspondence. Of course, the embodiment of the present disclosure does not limit the number of plugs 320 and plug slots 111 .

As can be seen from the foregoing, the surface contact between the first power connection surface 131 and the second power connection surface 3222 is the key to improving the stability of the plug connection between the busbar duct 1 and the plug connector 32 . The first power connection surface 131 of the busbar duct 1 and the second power connection surface 3222 of the plug connector 32 are introduced below respectively.

In this embodiment, three methods of elastic electrical connection between the conductive plate 13 and the power extraction blade 322 are provided, which will be introduced respectively below.

The first way, FIG. 10 is a schematic cross-sectional view of the bus duct. In this embodiment, the side of the conductive plate 13 exposed in the plug-in slot 111 has a planar structure. FIG. 11 is a schematic structural diagram of the plug connector 32. Compared with FIG. 3, FIG. 11 omits part of the insulating member 321 to better illustrate the power plug 322. With reference to Figure 11, one end of the power-taking plug 322 is connected to the insulating member 321, and the other end of the power-taking plug 322 is spaced apart from the insulating member 321, and has a power connection portion 3221 protruding away from the insulating member 321. The second power connection The surface 3222 is located at the power receiving portion 3221. The plug connector 32 is inserted into the plug slot 111, and the first power connection surface 131 presses the second power connection surface 3222, so that the first power connection surface 131 and the second power connection surface 3222 make elastic electrical contact (see Figure 9).

In the above implementation manner, the insulating member 321 provides a mounting base for one end of the power-taking blade 322 , so that the other end of the power-taking blade 322 is suspended and has a power connection portion 3221 protruding away from the insulating member 321 . In this way, the second power connection surface 3222 on the power connection part 3221 can elastically swing along with the power extraction blade 322, so that the second power connection surface 3222 on the power connection part 3221 can be close to the first power connection surface 131 , guaranteed to be By connection.

Figure 12 is a schematic structural diagram of the power-taking plug 322. With reference to Figure 12, in this embodiment, the power-taking plug 322 includes a plurality of conductive elastic pieces 3223. The plurality of conductive elastic pieces 3223 are independent of each other and arranged in a comb-tooth shape. Each conductive spring piece 3223 has a power connection portion 3221.

In the above implementation manner, by controlling the number of conductive spring pieces 3223, the size of the transmitted current can be adapted. For example, if the current transmitted by the plug connector 32 is relatively large, the area of the second electrical connection surface 3222 can be increased by increasing the number of conductive elastic pieces 3223 to allow the large current to pass.

In addition, since the power-taking insert 322 includes a plurality of conductive elastic pieces 3223, and these conductive elastic pieces 3223 are independent of each other, even if one or some conductive elastic pieces 3223 have poor contact with the conductive plate 13 due to deformation, it will not affect other conductive elastic pieces 3223. Conductive shrapnel 3223. In this way, it is ensured that the power-taking insert 322 and the conductive plate 13 still maintain good conduction.

In other embodiments, the power-taking plug-in piece 322 can also be an integral conductive elastic piece 3223. Such a design can ensure the structural strength of the conductive spring piece 3223 and be able to pass large currents.

Continuing to refer to FIG. 12 , in this embodiment, the power connection part 3221 includes a first inclined piece a1 , a flat piece a2 and a second inclined piece a3 that are connected in sequence. One end of the first inclined piece a1 and the second inclined piece a3 connected to the flat piece a2 protrudes from the insulating member 321, so that the flat piece a2 is spaced apart from the insulating member 321. The side of the flat piece a2 facing away from the insulating member 321 is the second electrical connection. Surface 3222 (the surface shown by the filled lines in Figure 12).

In the above implementation manner, when the plug connector 32 is inserted into the plug slot 111, the contact portion 3221 of each conductive elastic piece 3223 is squeezed, causing the first inclined piece a1 and the second inclined surface to deform in a flattening tendency, causing the The flat piece a2 is closely connected to the conductive plate 13 , that is, the first power connection surface 131 and the second power connection surface 3222 are closely connected, thereby achieving a stable connection between the power-taking insert 322 and the conductive plate 13 .

It should be noted that even if the conductive elastic piece 3223 is integrated with the electrical plug-in piece 322, the electrical connection portion 3221 can also include a first inclined piece a1, a flat piece a2 and a second inclined piece a3 that are connected in sequence.

Referring again to FIG. 3 , in this embodiment, the insulating member 321 includes a connected vertical plate 3211 and a guide part 3212 . Take the end of the electrical plug 322 close to the guide part 3212 and store it into the bottom and vertical part of the guide part 3212 . in the space between the plates 3211, and the second power connection surface 3222 is located outside the space between the bottom of the guide portion 3212 and the vertical plate 3211.

In one example, the end of the second inclined piece a3 away from the flat piece a2 is accommodated in the space between the bottom of the guide part 3212 and the vertical plate 3211 in order to protect the second inclined piece a3 and make the second inclined piece a3 The piece a3 will not be tilted away from the vertical plate 3211 during transportation and handling of the plug box. Among them, once connected to the power The portion 3221 is tilted outward, which will affect the insertion of the plug 320 into the insertion slot 111 .

The second power connection surface 3222 is located outside the space between the bottom of the guide portion 3212 and the vertical plate 3211 to prevent the guide portion 3212 from interfering with the contact between the second power connection surface 3222 and the first power connection surface 131 .

It can be seen that the guide portion 3212 of the insulating member 321 plays a role in protecting the power plug 322 and preventing the power plug 322 from tilting outward.

In addition, the guide portion 3212 of the insulating member 321 also plays a guiding role when the plug 320 is inserted into the insertion slot 111 to facilitate insertion.

In the second way, Figure 13 is a schematic cross-sectional view of the bus duct. The perspective of Figure 13 is the same as that of Figure 10. The difference is that the structure of the conductive plate 13 is different. With reference to Figure 13, in this embodiment, one side of the conductive plate 13 has a connection One end of the electrical elastic piece 1311 extends away from the conductive plate 13 , and the side of the electrical elastic piece 1311 facing away from the conductive plate 13 is the first electrical connection surface 131 . The side of the power plug 322 facing away from the insulating member 321 is the second power connection surface 3222. The plug connector 32 is inserted into the plug slot 111. The second power connection surface 3222 presses the first power connection surface 131 to make the first power connection surface 3222. The surface 131 is in elastic electrical contact with the second power connecting surface 3222.

In the above implementation manner, the power connection spring piece 1311 is connected to the conductive plate 13 . When the plug connector 32 is inserted into the plug slot 111, the power plug 322 can squeeze the power spring 1311, causing the power spring 1311 to elastically deform, thereby pressing against the power plug 322, that is, the second connection The electrical surface 3222 presses the first electrical connection surface 131 to make elastic electrical contact between the first electrical connection surface 131 and the second electrical connection surface 3222, thereby achieving stability between the second electrical connection surface 3222 and the first electrical connection surface 131. The contact improves the stable electrical connection between the busbar duct and the plug connector 32.

For example, while one end of the power-connecting spring piece 1311 extends away from the conductive plate 13 , it also extends away from the notch of the insertion slot 111 . Such a design can increase the insertion stroke of the plug connector 32 into the plug slot 111 , thereby preventing the plug connector 32 from being powered on prematurely during the process of being plugged into the plug slot 111 .

The third way, Figure 14 is a schematic cross-sectional view of the bus duct. The perspective of Figure 14 is the same as that of Figure 10. The difference is that the structure of the conductive plate 13 is different. With reference to Figure 14, in this embodiment, one side of the conductive plate 13 has a connection The electrical protrusion 123 protrudes away from the conductive plate 13 and is exposed in the plug slot 111 . The side of the electrical protrusion 123 facing away from the conductive plate 13 is the first electrical connection surface 131 . There is a gap between one end of the power extraction blade 322 and the insulating member 321. The second power connection surface 3222 is located at one end of the power extraction blade 322. The plug connector 32 is inserted into the plug slot 111, and the first power connection surface 131 presses the second power connection surface 3222. The power connection surface 3222 is connected to the first power connection surface 131 and the second power connection surface 3222 to make elastic electrical contact.

In the above implementation manner, the power connection protrusion 123 is connected to the conductive plate 13 . Plug in plug connector 32 When inserted into the insertion slot 111, the power-taking plug 322 and the power-connecting protrusion 123 are pressed against each other, that is, the first power-connecting surface 131 is pressed against the second power-connecting surface 3222, so that the two are in close contact with each other. This further achieves stable contact between the first power connection surface 131 on the power connection protrusion 123 and the second power connection surface 3222 on the power extraction blade 322, thereby improving the stable electrical connection between the busbar duct and the plug connector 32.

Referring to Figure 10 again, in this embodiment, the bus duct 1 also includes an insulating bracket 12. The length direction of the insulating bracket 12 is consistent with the length direction of the slot wall of the plug-in slot 111. The conductive plate 13 is located in the insulating bracket 12, and the conductive plate 13 is located in the insulating bracket 12. The first electrical connection surface 131 of 13 is exposed in the plug slot 111.

In the above implementation manner, the insulating bracket 12 is installed in the plug slot 111 to provide a mounting base for the conductive plate 13 , and the conductive plate 13 is installed on the insulating bracket 12 to achieve insulation between the conductive plate 13 and the housing 11 Install.

Exemplarily, both the insulating bracket 12 and the conductive plate 13 are in the shape of a long strip, the conductive plate 13 is located in the insulating bracket 12, and the insulating bracket 12 half wraps the conductive plate 13, so that the conductive plate 13 has a surface exposed in the plug slot 111. The first electrical connection surface 131 is in order to be in contact with the second electrical connection surface 3222 of the plug-in box for conduction.

Illustratively, the conductive plate 13 is a copper plate and is used for transmitting electricity. The number of conductive plates 13 corresponds to the format of the power distribution system. For example, if the power distribution system is a three-phase five-wire system, the bus duct 1 includes five conductive plates 13, and the five conductive plates 13 respectively correspond to three phase wires, one neutral wire, and one ground wire. If the power distribution system is a three-phase four-wire system, then the bus duct 1 includes four conductive plates 13, and the four conductive plates 13 respectively correspond to three phase wires and a neutral wire, or three phase wires and a ground wire.

Continuing to refer to FIG. 10 , in this embodiment, the plurality of plug-in slots 111 include at least one first plug-in slot 111A. Two insulating brackets 12 are installed in the first plug-in slot 111A, and the two insulating brackets 12 are respectively located at two opposite slot walls of the first plug-in slot 111A. The conductive plates 13 in the two insulating brackets 12 are The first electrically connected surfaces 131 are opposite and have a distance.

In the above implementation manner, the first plug-in slot 111A is a type of plug-in slot 111 . The first plug slot 111A corresponds to the second and third plug slots 111 from left to right in FIG. 10 . In the first plug slot 111A, there are two insulating brackets 12 corresponding to two conductive plates 13. The first contact surfaces 131 of the two conductive plates 13 are relatively spaced apart and can be connected to two different second conductive plates 13 respectively. The connection surfaces 3222 are in contact, thereby making the structure of the busbar duct 1 more compact.

Continuing to refer to Figure 10, in this embodiment, the plurality of plug-in slots 111 also include a second plug-in slot 111B. An insulating bracket 12 is installed in the second plug-in slot 111B, and the insulating bracket 12 is located in the second plug-in slot. At a groove wall of 111B, the first electrical connection surface 131 and the second plug-in connection of the conductive plate 13 in the insulating bracket 12 The other groove wall of groove 111B is opposite and spaced apart.

In the above implementation manner, the second plug-in slot 111B is another type of plug-in slot 111 . The second plug-in slot 111B corresponds to the first plug-in slot 111 from left to right in FIG. 10 . In the second plug slot 111B, there is an insulating bracket 12 and a corresponding conductive plate 13. The first conductive surface 131 of the conductive plate 13 is arranged relatively spaced apart from the wall of the plug slot 111 and can be connected with a third The two electrical planes 3222 are in contact. Since there is only one conductive plate 13 in the insertion slot 111, the connection between the first power connection surface 131 and the second power connection surface 3222 is more reliable.

In one example, in order to promote the conductive plate 13 to be stabilized in the plug-in slot 111, for example, during transportation and handling of the bus duct, the conductive plate 13 can be stabilized in the plug-in slot 111 without position deviation or shaking. correspondingly, the bus duct may also include a limit spring hook, which is installed on the end cover of the bus duct and used to clamp the conductive plate 13 to reduce the shaking of the conductive plate 13. For details, please refer to the following.

As shown in FIG. 15 , the housing 11 includes a socket 112 for forming the insertion slot 111 and two end caps 113 . The two end caps 113 are respectively installed at both ends of the socket 112 along the length direction. As shown in FIG. 15 and with reference to FIG. 16 , the end cap 113 has a through hole 1131 that is adapted to the conductive plate 13 and is used for the conductive plate 13 to pass through.

Continuing to refer to FIG. 16 , the inner surface of the end cap 113 is equipped with limited spring hooks 14 on both sides of the through hole 1131 . For example, as shown in Figure 17, the inner surface of the end cap 113 has a spring hook groove 1132 at the position of the through hole 1131. The limiting spring hook 14 is installed in the spring hook groove 1132, and the spring hook portion extends out of the spring hook groove. 1132.

In this way, as shown in Figure 18, the two limiting spring hooks 14 located on both sides of the through hole 1131 elastically clamp the conductive plate 13 passing through the through hole 1131, and can limit the conductive plate 13 along the left and right sides of the through hole 1131. The directions on both sides sway left and right. In addition, the two limiting spring hooks 14 on the two end caps 113 located on the same side of the through hole 1131 also elastically clamp the conductive plate 13 passing through the through hole 1131, and can limit the conductive plate 13 along the through hole 1131. rocking up and down along its length.

In one example, during the process of assembling the bus duct, the conductive plate 13 can be first inserted into the insulating bracket 12. After the two are combined together, they are inserted into the plug-in slot 111 as a whole. Alternatively, the insulating bracket 12 may be inserted into the insertion slot 111 first, and then the conductive plate 13 may be inserted into the insulating bracket 12 . Among them, this embodiment does not limit the process of inserting the insulating bracket 12 and the conductive plate 13 into the plug-in slot 111 .

Afterwards, the limiting spring hooks 14 can be inserted into the spring hook grooves 1132 of the end cover 113 respectively, and then The end cap 113 inserted into the limiting spring hook 14 is fixed at the end of the slot base 112 .

During the process of fixing the end cover 113 to the slot base 112, first the through hole 1131 of the end cover 113 is placed outside the conductive plate 13, and then the end cover 113 moves along the conductive plate 13 to the end of the slot base 112, and connects with the slot. The seats 112 are fixed together.

It should be pointed out that when the end cover 113 equipped with the limit spring hook 14 moves along the conductive plate 13, since the movement direction of the limit spring hook 14 complies with the deformation direction of the limit spring hook 14, then the end cover 113 can then move along the conductive plate 13 to the end of the groove base 112 relatively easily.

When the bus duct needs to be disassembled, the end cover 113 equipped with the limit spring hook 14 needs to be removed from the slot base 112. When disassembling, the end cover 113 moves along the conductive plate 13 but not along the limit spring hook 14. deformation direction, then the end cap 113 needs force to move away from the conductive plate 13 .

In order to facilitate the removal of the end cover 113 installed with the limited spring hook 14 along the conductive plate 13, the limited spring hook 14 can be detachably inserted into the spring hook groove 1132 of the end cover 113. middle. For example, the limit spring hook 14 is inserted into the spring hook groove 1132 of the end cover 113. When no force is applied to the limit spring hook 14 or a small force is applied to the limit spring hook 14, the limit spring hook 14 will not exit from the spring hook groove 1132. When a greater force is applied to the limit spring hook 14, the limit spring hook 14 can fall off from the spring hook groove 1132. In this way, when it is necessary to remove the end cover 113 equipped with the limited spring hook 14 from the socket 112, the fixed relationship between the end cover 113 and the socket 112 is first removed, and then the end cover 113 is pulled out along the conductive plate 13. When the cover 113 is pulled out along the conductive plate 13, the limit spring hook 14 is still clamping the conductive plate 13, and the end cover 113 is subjected to external force, then the limit spring hook 14 can fall off from the spring hook groove 1132, and then The removal of the end cap 113 will not be restricted. It can be seen that the limit spring hook 14 is detachably inserted into the spring hook groove 1132 of the end cover 113, which can facilitate the disassembly of the bus duct and improve the disassembly and assembly efficiency of the bus duct.

In one example, the bus duct can not only be used to transmit power, but can also be used to hold additional wiring harnesses, such as weak wires, specifically network cables, etc. Accordingly, refer to the housing shown in Figures 2 and 4. 11 also has additional slots 114 along the length direction. The additional slots 114 can be used to place additional wire bundles. The additional wire bundles can be weak wires and optical fibers.

As shown in FIGS. 2 and 4 , the slot of the additional slot 114 is located on one side of the housing 11 along the length direction, and is located on a different side from the slot of the plug-in slot 111 . This is because the slot of the plug-in slot 111 is used for plugging in the plug connector 32 of the plug-in box. Therefore, in order not to affect the plug-in of the plug connector 32, the side of the slot of the additional slot 114 is different from that of the plug-in slot 111. The side where the notch is located.

For example, if the bus duct is suspended from the top of the IDC computer room, then the slot of the plug-in slot 111 is located on the bus duct. The lower side of the slot faces the ground, the installation side of the bus duct is located on the upper side facing the ceiling, and the notch of the additional slot 114 is located on the left or right side of the bus duct.

In one example, in order to close the additional slot 114, as shown in Figures 2 and 4, the housing 11 further includes an additional slot cover 115. The additional slot cover 115 is closed on the slot of the additional slot 114, for example, by snapping. The opening of the additional slot 114 is covered in a closed manner.

In one example, in order for additional wire harnesses to be introduced into and passed out of the additional slots 114 , there is a gap between the additional slots 114 and the additional slot cover 115 for the additional wire harnesses to pass through. . Or, in another example, the end cap 113 has additional through holes at positions corresponding to the additional slots 114, and the additional through holes are used for additional wire harnesses to pass through.

Figure 19 is a cross-sectional view of the bus duct. With reference to Figure 19, in this embodiment, the conductive plate 13 is located in the plug-in slot 111, and the conductive plate 13 is insulated from the shell 11. The conductive plate 13 has a plug-in connection with the plug-in box. The first power connection surface 131 of the connector is contacted by the power insert 322 . There are two conductive plates 13 in the plug slot 111, and the polarities of the two conductive plates 13 are different from each other.

One side of the housing 11 has a plug-in slot 111 for accommodating the conductive plate 13 and providing a mounting base for the conductive plate 13 . The conductive plate 13 is installed in the plug slot 111. The conductive plate 13 is insulated from the housing 11 to ensure the safety of electricity. The conductive plate 13 has a first electrical connection surface 131, and the first electrical connection surface 131 is exposed to the plug socket. The slot 111 is used to contact the power-taking blade 322 of the plug connector 32 of the plug-in box 3 to realize the electrical connection between the bus duct and the plug-in box 3 . Since there are two conductive plates 13 in the plug-in slot 111, and the polarities of the two conductive plates 13 are different from each other, when a plug connector 32 is plugged into a plug-in slot 111, the plug connector 32 can be Electrical connections are made with both polarities (see Figure 9). In this way, the number of plug-in slots 111 is effectively reduced, making the structure of the bus duct simpler, which is beneficial to realizing a miniaturized design of the bus duct.

In addition, after the plug connector 32 of the plug-in box 3 is inserted into the plug-in slot 111 along the depth direction of the plug-in slot 111 , the power-taking blade 322 of the plug-in connector 32 can be connected with the conductive plate 13 The first electrical connection surface 131 is in contact, and no other operations are required to achieve a quick electrical connection between the bus duct and the plug-in box 3 .

In one application, the side where the notch of the plug-in slot 111 is located is the plug-in side of the bus duct, and the side of the bus duct facing away from the plug-in side is the installation side. The installation side of the bus duct can be installed on the IDC On the top of the computer room, the plug-in slot 111 of the bus duct faces the ground of the IDC machine room. The technician can hold the plug-in box 3 and insert the plug connectors 32 of the plug-in box 3 into the bus duct. For example, insert the plug connectors 32 one by one. to the plug-in slot 111 of the bus duct, so that the plug-in box 3 can take power in the bus duct.

In this embodiment, the bus duct may be a small bus duct, which is a bus duct that transmits a current within 800A. Of course, the bus duct may also be a large bus duct, and the embodiment of the present disclosure does not limit the specific type of the bus duct.

As can be seen from the foregoing, the arrangement of the conductive plate 13 in the plug-in slot 111 is the key to realizing the "one slot and two poles" of the bus duct. The arrangement of the conductive plate 13 will be introduced below.

Referring to Figure 19, in this embodiment, the plurality of plug-in slots 111 include at least one first plug-in slot 1111. The first plug-in slot 1111 has two conductive plates 13, and the two conductive plates 13 are respectively located on the first plug-in slot 1111. At two opposite slot walls of the insertion slot 1111, the two conductive plates 13 are opposite and have a distance.

In the above implementation manner, the first plug-in slot 1111 is a type of plug-in slot 111 . The first plug-in slot 1111 corresponds to the second and third plug-in slot 111 from left to right in FIG. 19 . In the first plug slot 1111, there are two conductive plates 13. The first contact surfaces 131 of the two conductive plates 13 are arranged relatively spaced apart and can be in contact with the power-taking blades 322 of the plug connector 32 respectively, thereby realizing "one "Trough poles" makes the structure of the bus duct more compact.

Continuing to refer to Figure 19, in this embodiment, the plurality of plug-in slots 111 also include a second plug-in slot 1112. The second plug-in slot 1112 has a conductive plate 13, and the conductive plate 13 is located in the second plug-in slot. At one groove wall of 1112, the conductive plate 13 is opposite to the other groove wall of the second plug-in slot 1112 and has a distance.

In the above implementation manner, the second plug-in slot 1112 is another type of the plug-in slot 111 . The second plug-in slot 1112 corresponds to the first plug-in slot 111 from left to right in FIG. 19 . In the second plug slot 1112, there is a conductive plate 13. The first conductive surface 131 of the conductive plate 13 is arranged relatively spaced apart from the slot wall of the plug slot 111, and can be in contact with the power extraction blade 322 of the plug connector 32. .

That is to say, the plug-in slot 111 has two types, one type is the first plug-in slot 1111, which has two conductive plates 13, and the other type is the second plug-in slot 1112, which has one conductive plate 13. The selection of the type of plug-in slot 111 is related to the number of conductive plates 13 of the bus duct. Classification discussion follows.

If the number of conductive plates 13 of the bus duct is an even number, then all the plug-in slots 111 can be the first plug-in slots 1111, or some of the plug-in slots 111 can be the first plug-in slots 1111, and the remaining even numbers can be the first plug-in slots 1111. The slot 111 is the second plug slot 1112.

If the number of conductive plates 13 in the bus duct is an odd number, then the plurality of plug-in slots 111 include both the first plug-in slot 1111 and the second plug-in slot 1112. For example, the number of the second plug-in slot 1112 is one, and the rest are first plug-in slots 1111 .

Further, the number of conductive plates 13 is related to the format of the power distribution system. Exemplarily, the conductive plate 13 It is a copper plate used to transmit electricity. For example, if the power distribution system is a three-phase five-wire system, the bus duct includes five conductive plates 13, and the five conductive plates 13 respectively correspond to three phase wires, one neutral wire, and one ground wire. If the power distribution system is a three-phase four-wire system, then the bus duct includes four conductive plates 13, and the four conductive plates 13 respectively correspond to three phase wires and a neutral wire, or three phase wires and a ground wire.

In this embodiment, if the power distribution system is a three-phase five-wire system, then the bus duct includes five conductive plates 13 , that is, the number of conductive plates 13 is an odd number. In this case, the plug-in slot 111 includes two first plug-in slots 1111 and one second plug-in slot 1112, wherein the two first plug-in slots 1111 respectively accommodate the conductive plates 13 (phases) corresponding to the three phase wires. A conductive plate 13 (pole conductive plate) and a conductive plate 13 corresponding to a neutral line (neutral conductive plate), and a second plug slot 1112 accommodates a conductive plate 13 (ground conductive plate) corresponding to a ground wire. If the power distribution system is a three-phase four-wire system, then the bus duct includes four conductive plates 13, that is, the number of conductive plates 13 is an even number. In this case, the plug-in slot 111 includes two first plug-in slots 1111, respectively accommodating the conductive plates 13 corresponding to three phase lines and the conductive plate 13 corresponding to one neutral line.

Of course, the above arrangement of the conductive plate 13 is only an example, and the present disclosure does not limit it.

For example, the distance between the two conductive plates 13 in the first plug slot 1111 is less than or equal to 12.5 mm.

In the above implementation, the distance d1 between the first contact surfaces 131 of the two conductive plates 13 in the first plug slot 1111 is less than or equal to 12.5 mm, so that the bus duct can meet the IP2X standard to avoid the need for technicians to Put your hand into the distance d1, causing an electric shock.

For example, the distance between the conductive plate 13 in the second plug slot 1112 and the opposite slot wall is less than or equal to 12.5 mm.

In the above implementation manner, the distance d2 between the first contact surface 131 of the conductive plate 13 in the second plug slot 1112 and the opposite slot wall is less than or equal to 12.5 mm, so that the bus duct can meet the IP2X standard to Prevent technicians from extending their hands into the distance d2 and causing electric shock.

It should be noted that if the conductive plate in the second plug slot 1112 is a ground conductive plate, even if a technician puts his hand in, no electric shock will occur. Therefore, the conductive plate 13 and the wall of the plug slot 111 The distance d2 between them may not be limited.

Continuing to refer to Figure 19, in this embodiment, the bus duct also includes an insulating bracket 12. The insulating bracket 12 is located in the plug-in slot 111. The length direction of the insulating bracket 12 is consistent with the length direction of the wall of the plug-in slot 111. The conductive plate 13 is located in the insulating bracket 12 , and the first electrical connection surface 131 of the conductive plate 13 is exposed in the plug slot 111 .

Exemplarily, both the insulating bracket 12 and the conductive plate 13 are in the shape of a long strip, the conductive plate 13 is located in the insulating bracket 12, and the insulating bracket 12 half wraps the conductive plate 13, so that the conductive plate 13 has a surface exposed in the plug slot 111. The first power connection surface 131 is in order to be in contact with the power extraction blade 322 of the plug-in box 3 for conduction.

It should be noted that since the insulating brackets 12 are used to realize the insulating installation of the conductive plates 13 in the insertion slots 111 , the number of the insulating brackets 12 is the same as the number of the conductive plates 13 . That is to say, the number of insulating brackets 12 in the first plug-in slot 1111 is two, and the number of insulating brackets 12 in the second plug-in slot 1112 is one.

Continuing to refer to FIG. 19 , in this embodiment, the insulating bracket 12 has a through slot 121 extending along its length direction, and the slot of the through slot 121 is located in the insertion slot 111 . The conductive plate 13 is located in the through slot 121 , and the first conductive surface 131 of the conductive plate 13 is exposed in the plug-in slot 111 through the opening of the through slot 121 .

In the above implementation manner, the insulating bracket 12 has a through slot 121. The through slot 121 is used to provide an installation space for the conductive plate 13. The conductive plate 13 is plugged into the through slot 121 and exposes the first electrical connection surface 131 to the plug. In the groove 111, the insulation installation between the conductive plate 13 and the housing 11 is realized, ensuring the safety of electricity use.

In this embodiment, the groove wall of the through groove 121 has a protruding stop 121a, the protruding stop 121a protrudes from the groove wall of the through groove 121, and the protruding stop 121a is located at the opening of the through groove 121. The first conductive surface 131 of the conductive plate 13 has a female stop 131a, and the female stop 131a and the male stop 121a are plugged together.

In this embodiment, the convex stop 121a and the concave stop 131a can cooperate with each other, so that the conductive plate 13 is clamped in the through groove 121, thereby achieving a stable installation between the conductive plate 13 and the insulating bracket 12.

Figure 20 is a cross-sectional view of the bus duct. The difference between Figure 20 and Figure 19 mainly lies in the related structure of the conductive plate 13. Referring to FIG. 20 , in this embodiment, one side of the conductive plate 13 has a conductive spring piece 1311 . One end of the power-connecting elastic piece 1311 extends away from the conductive plate 13 , and a side of the power-connecting elastic piece 1311 facing away from the conductive plate 13 is the first power-connecting surface 131 .

In the above implementation manner, the power connection spring piece 1311 is connected to the conductive plate 13 . When the plug connector 32 of the plug-in box 3 is plugged into the plug-in slot 111, the plug connector 32 of the plug-in box 3 can squeeze the power-connecting elastic piece 1311, causing the power-connecting elastic piece 1311 to elastically deform, thereby pressing the plug connector 32 on the power-taking plug-in piece 322, thereby achieving stable contact between the first power-connecting surface 131 on the power-connecting spring piece 1311 and the plug connector 32, thereby improving the stable electrical connection between the busbar duct and the plug-in box 3.

Figure 21 is a cross-sectional view of the bus duct. The difference between Figure 21 and Figure 19 mainly lies in the related structure of the conductive plate 13. 21 , in this embodiment, one side of the conductive plate 13 has a power connection protrusion 1312 . The power connection protrusion 1312 protrudes away from the conductive plate 13 , and a side of the power connection protrusion 1312 facing away from the conductive plate 13 is the first power connection surface 131 .

In the above implementation manner, the power connection protrusion 1312 is connected to the conductive plate 13 . When the plug connector 32 of the plug-in box 3 is plugged into the plug-in slot 111, the plug connector 32 of the plug-in box 3 and the power connection protrusion 1312 are pressed against each other, so that they are in close contact with each other, thereby realizing the connection. The stable contact between the first electrical connection surface 131 on the electrical elastic piece 1311 and the plug connector 32 improves the stable electrical connection between the bus duct and the plug-in box 3 .

Continuing to refer to FIG. 21 , in this embodiment, when the conductive plate 13 is a ground conductive plate, the distance between the power connection protrusion 1312 and the notch of the plug-in slot 111 is the first distance d3. When the conductive plate 13 is a phase conductive plate or a neutral conductive plate, the distance between the power connection protrusion 1312 and the notch of the plug-in slot 111 is the second distance d4, and the first distance d3 is smaller than the second distance d4.

In the above implementation manner, since the first distance d3 is smaller than the second distance d4, when the plug connector 32 is inserted into the plug slot 111, the power-taking blade 322 of the plug connector 32 is first connected to the ground conductive plate. The electrical protrusions 1312 come into contact. As the plug connector 32 moves, the power-taking blade 322 of the plug connector 32 will then come into contact with the electrical protrusions 1312 of the phase conductive plate or the neutral conductive plate. In this way, priority grounding of the plug connector 32 can be achieved, meeting the safety standard of ground pole first conduction.

It should be noted that the first distance d3 and the second distance d4 may be determined by the relative positions of the power-connecting protrusions 1312 on the conductive plate 13 . For example, if the power connection protrusion 1312 is close to the notch of the plug slot 111, the first distance d3 can be made smaller, otherwise, the first distance d3 can be made larger, and the same is true for the second distance d4. In addition, the first distance d3 and the second distance d4 may be determined by the relative position between the conductive plate 13 and the notch of the plug-in slot 111 . For example, if the conductive plate 13 is close to the opening of the plug-in slot 111, the first distance d3 will be smaller, otherwise, the first distance d3 will be larger, and the same applies to the second distance d4.

Figure 22 is a cross-sectional view of the bus duct. The main difference between Figure 22 and Figure 19 is that the bus duct also includes a dust cover 140. The dust cover 140 is located at the notch of the plug-in slot 111 and covers the slot of the plug-in slot 111. mouth.

By covering the plug-in slot 111 with the dust-proof cover 140 , debris can be effectively prevented from entering the plug-in slot 111 through the notch of the plug-in slot 111 . It is easy to understand that although the dust cover 140 is disposed at the notch of the plug slot 111 , but the dust cover 140 should not affect the plug connector 32 of the plug box 3.

In this embodiment, the bus duct can not only be used to transmit power, but can also be used to hold additional wire bundles, such as weak wires, network wires, etc. Referring to FIG. 19 , the housing 11 also has an additional slot 114 along the length direction. The slot of the additional slot 114 is located on one side of the housing 11 along the length direction and is on a different side from the slot of the plug-in slot 111 .

In the above implementation manner, the slot of the additional slot 114 is located on one side of the housing 11 along the length direction, and is located on a different side from the slot of the plug-in slot 111 . This is because the slot of the plug-in slot 111 is used for plugging in the plug connector 32 of the plug-in box 3. Therefore, in order not to affect the plug-in of the plug connector 32, the side of the slot of the additional slot 114 is different from the side of the plug-in slot 111. The side where the notch is located.

For example, if the bus duct is suspended from the top of the IDC computer room, then the slot of the plug-in slot 111 is located on the lower side of the bus duct facing the ground, the installation side of the bus duct is on the upper side facing the ceiling, and the slot of the additional slot 114 is located on the bus duct. left or right side of the slot.

In one example, in order to close the additional slot 114, the housing 11 further includes an additional slot cover 115. The additional slot cover 115 is closed on the notch of the additional slot 114. For example, it can be closed on the additional slot 114 in a snap-fit manner. notch.

In one example, in order for additional wire harnesses to be introduced into and passed out of the additional slots 114 , there is a gap between the additional slots 114 and the additional slot cover 115 for the additional wire harnesses to pass through. .

The above is the structural introduction of the bus duct. Based on the above, the bus duct has at least the following effects.

The plurality of plug-in slots 111 of the bus duct include a first plug-in slot 111A. Two conductive plates 13 can be installed in the first plug-in slot 111A to realize one slot with two poles. This reduces the number of plug-in slots compared with one slot and one pole. The number of slots can reduce the overall size of the bus duct.

Moreover, although the first plug-in slot 111A can realize one slot and two poles, the distance between the first contact surfaces 131 of the two conductive plates 13 in the first plug-in slot 111A can still meet the IP2X standard and comply with safety regulations.

The outer end surface of the lower slot wall 123 of the phase insulating bracket 12A among the multiple insulating brackets 12 of the bus duct protrudes from the first contact surface 131 of the supported phase conductive plate 13A, so that the plug connector of the plug-in box 3 During the process of inserting 32 into the bus duct, the phase conductive plate 13A and the plug connector 32 are delayed in connection. The delayed conduction does not mean that the plug connector 32 and the bus duct are connected as soon as they are inserted, but that they are connected after being inserted for a certain distance. Once the phase conductive plate 13A and the plug connector 32 are connected after a delay, the risk of electric shock for technicians during plugging can be reduced and the risk of electric shock can be improved. The safety of use of bus duct.

In addition, the outer end surface of the lower slot wall 123 of the phase insulating bracket 12A among the multiple insulating brackets 12 of the bus duct protrudes from the first contact surface 131 of the supported phase conductive plate 13A, and the ground insulating bracket 12B The outer end surface of the lower groove wall 123 is flush with or recessed in the first connection surface 131 of the supported ground conductive plate 13B, so that when the plug connector 32 of the plug-in box 3 is inserted into the bus duct, the ground electrode The conductive plate 13B is first connected to the phase conductive plate 13A and the plug connector 32 . Once the ground conductive plate 13B is connected to the plug connector 32, the current can be directed to the earth, which can further reduce the risk of electric shock for technicians during plugging and improve the safety of the bus duct.

The plug-in slot 111 can be adapted to conductive plates 13 of different cross-sectional sizes. For example, the second plug-in slot 111B can be adapted to ground electrode conductive plates 13B of different cross-sectional sizes. This can reduce the processing of the housing 11 and eliminates the need for lengthy processing. Multiple shells 11 can be used to adapt to conductive plates 13 of different sizes, thereby saving mold investment in processing the shells 11 and saving processing costs.

The bus duct includes a plurality of limit spring hooks 14. The left and right sides of the conductive plate 13 along the thickness direction are clamped by the limit spring hooks 14, which can limit the left and right shaking of the conductive plate 13 along the thickness direction. The same side of the conductive plate 13 It is clamped by two limiting spring hooks 14 along the length direction, which can limit the conductive plate 13 from shaking up and down along the length direction. This further enhances the stability of the conductive plate 13 in the plug slot 111, which is beneficial to the transportation and handling of the bus duct.

In addition, the limiting spring hook 14 is pluggably installed in the spring hook groove 1132 of the end cover 113, so that in the assembled bus duct, the end cover 113 with the limiting spring hook 14 installed can smoothly move to the slot along the conductive plate 13. 112 places to facilitate the assembly of bus duct. When disassembling the bus duct, when the end cover 113 moves away from the slot seat 112 along the conductive plate 13, the limiting spring hook 14 and the spring hook groove 1132 of the end cover 113 are separated, without blocking the end cover from moving along the conductive plate 13. The trough seat 112 facilitates the disassembly of the bus duct.

The bus duct not only includes plug-in slots 111, but also includes additional slots 114. The additional slots 114 can be used for additional wire harnesses to pass through, such as weak wires, so that the bus duct has power transmission functions and additional wire harness organizing functions, enriching the Application of bus duct.

The above is an introduction to bus ducts. The connectors that connect two adjacent bus ducts will be introduced below.

(2) Connectors.

A power distribution system generally includes multiple bus ducts, and two adjacent bus ducts are connected through connectors to extend the path of the transmission line.

It should be noted that the bus duct connected to the connector may be the bus duct described in (1) above, or may be other types of bus duct, which is not limited in this embodiment.

As shown in FIG. 23 , the connector 2 includes a plurality of crimping guide plates 21 , a plurality of insulating baffles 22 , two pressing plates 23 and fixing bolts 24 . The plurality of crimping guide plates 21, the plurality of insulation baffles 22 and the two pressure plates 23 all have mounting holes. As shown in FIG. 24 , a plurality of crimping guide plates 21 , a plurality of insulating baffles 22 and two pressure plates 23 are arranged in a stack and connected through fixing bolts 24 .

Among them, one surface of each crimping guide plate 21 is fixed on the surface of the insulating baffle 22, and the other is used to contact the conductive plate 13 of the busbar 1. The two pressing plates 23 are respectively located on the outermost layer.

In one example, the pressure plate 23 is generally made of metal and is conductive. In order to prevent technicians from getting an electric shock by touching the pressure plate 23 during installation, the thing in contact with the pressure plate 23 can be an insulating baffle 22 or a The crimping guide plate 21 comes into contact with the ground conductive plate 13B.

Then, if the bus duct 1 includes the ground conductive plate 13B, then among the plurality of insulating baffles 22, one of the outermost insulating baffles 22 is in contact with a pressure plate 23, and the other outermost insulating baffle 22 is in contact with a pressing plate 23. A crimping guide plate 21 for contacting the ground conductive plate is fixed on the outer surface. The crimping guide plate 21 is adjacent to another pressing plate 23 and has a gap for the ground conductive plate to be inserted.

Of course, in the solution in which the bus duct 1 includes the ground conductive plate 13B, the two pressing plates 23 can respectively contact two of the multiple insulating baffles 22 , that is, multiple insulating baffles 22, one outermost insulating baffle 22 is in contact with one pressure plate 23, and the other outermost insulating baffle 22 is in contact with the other pressure plate 23.

And if the bus duct 1 does not include a ground conductive plate, then among the plurality of insulating baffles 22, one outermost insulating baffle 22 is in contact with one pressure plate 23, and the other outermost insulating baffle 22 is in contact with another The pressure plate 23 is in contact.

In one example, both surfaces of the insulating baffle 22 that are not in contact with the pressing plate 23 may be fixed with crimping guide plates 21 to ensure the conduction stability of the connector and the busbar duct. A crimping guide plate 21 is fixed on a surface of the insulating baffle 22 that is in contact with the pressure plate 23 and away from the pressure plate 23 to prevent the pressure plate 23 from being electrified.

The connection relationship between the connector and the bus duct will be introduced below. The bus duct is exemplified by the above-mentioned bus duct.

For the convenience of description, the length direction along the fixing bolt 24 in Figure 24 can be recorded as the left and right direction, The nut of the fixing bolt 24 is the right end, and the other end is the left end. The insulating baffles 22 from left to right are sequentially designated as the first insulating baffle, the second insulating baffle, the third insulating baffle, the fourth insulating baffle and the fifth insulating baffle.

As shown in Figure 24, there is a gap between the crimping guide plate 21 on the right side of the first insulating baffle and the crimping guide plate 21 on the left side of the second insulating baffle. There is a gap between the crimping guide plate 21 and the crimping guide plate 21 on the left side of the third insulating baffle, and the crimping guide plate 21 on the right side of the third insulating baffle and the crimping guide plate 21 on the left side of the fourth insulating baffle. There is a spacing between the crimping guide plate 21 on the right side of the fourth insulating baffle and the crimping guide plate 21 on the left side of the fifth insulating baffle. The crimping guide plate 21 on the right side of the fifth insulating baffle is There is a gap between 21 and the pressure plate 23 on the right side, and the above gap is used for the conductive plate 13 to be inserted.

As shown in Figure 25, the parts of each conductive plate 13 of a busbar that protrude from the end cover 113 are inserted into the above-mentioned spacing, and are located on one side of the fixing bolt 24 (the upper side of Figure 25), and on the other side The portions of each conductive plate 13 of the busbar that protrude from the end cover 113 are inserted into the above-mentioned spacing and are located on the other side of the fixing bolts 24 (the lower side in Figure 25). After the fixing bolt 24 is tightened, the bus ducts on both sides of the fixing bolt 24 are in close contact with the crimping guide plate 21 of the connector and are electrically connected, thus realizing the electrical connection between the two bus ducts.

In one example, for safety, as shown in Figure 25, the connector also includes a connector shell 25, and the connector shell 25 is fastened on the shell 11 of the bus duct 1 to press the connector. The connecting guide plate 21, the insulating baffle 22, the pressure plate 23 and the fixing bolts 24 are closed to avoid accidental contact and electric shock.

In one example, in order to make the conductive plate 13 of the busbar and the crimping guide plate 21 of the connector in close contact to ensure good conduction, correspondingly, as shown in Figure 26, the pressure plate 23 can be an arc plate, and the pressure plate The mounting hole 23 is located at the center of the arc plate, and the two pressure plates 23 are located in the outermost layer in a bracket shape. The pressing plate 23 is a deformable metal plate. During tightening, the fixing bolts 24 can be deformed from an arc plate into a flat plate through the pressing plate 23, so that the crimping guide plate 21 of the connector and the conductive plate 13 of the bus duct are closely attached. together to ensure good conduction between the two.

In one example, in order to monitor the good conduction between the crimping guide plate 21 and the conductive plate 13, the connector may include multiple temperature sensors and indicating components, and each temperature sensor is in contact with one crimping guide plate 21. , to monitor the temperature of the crimping guide plate 21. The indicating component may be an indicator light, and the number thereof may be multiple. Each indicator light is electrically connected to a temperature sensor to indicate the detection result of the temperature sensor. Alternatively, the indicating component can also be a display screen, and multiple temperature sensors are electrically connected to the display screen. The detection results of each temperature sensor can be displayed on the display screen.

When the connector and the bus duct are connected, once the contact between a certain crimping guide plate 21 and the conductive plate 13 is not good, the resistance between the two will be greater and more heat will be generated, then the contact with the crimping guide plate 21 will The temperature sensor can detect a higher temperature, and the indicating component electrically connected to the temperature sensor can indicate that the temperature sensor detects a high temperature. If the indicator light turns on, then according to the corresponding relationship between the indicating component, the temperature sensor and the crimping guide plate 21 relationship, it can be found out which crimping guide plate 21 and the conductive plate 13 have poor conduction, which is helpful to eliminate connection faults.

When the connector and the bus duct are connected and the contact between the crimping guide plate 21 and the conductive plate 13 is good, the resistance between the two is small and the heat generated is small, then the temperature sensor in contact with the crimping guide plate 21 cannot detect it. If the temperature is high, the indicating component electrically connected to the temperature sensor can indicate that the temperature sensor detects low temperature, for example, the indicator light does not light up.

In this way, the connector includes a temperature sensor and an indication component, which allows technicians to know at a glance whether the conduction between each crimping guide plate 21 and the conductive plate 13 is good.

In one example, in order to simplify the structure of the connector, the mounting hole of one of the two pressure plates 23 has internal threads, so that the fixing bolt 24 can be threadedly connected to the pressure plate 23 with internal threads. Then, the fixing bolt 24 No need to use nuts to connect the ends.

The pressure plate 23 in the above connector is an arc plate and has the function of a gasket, so the gasket can be omitted. The mounting hole of the pressure plate 23 is a screw hole and has the function of a nut, so the nut can be omitted. It can be seen that the connector has a streamlined structure and is simple to assemble, which is beneficial to improving assembly efficiency.

The above is the structural introduction of the connector. Based on the above, the connector has at least the following effects.

The fixing parts of the connector only include two pressure plates 23 and one bolt. The pressure plate 23 integrates the functions of a gasket and a nut, which simplifies the structure of the connector and helps improve assembly efficiency.

The connector includes a temperature sensor and an indicating component, which can monitor in real time whether the conduction between each crimping guide plate and the conductive plate is good, so that technicians can know the conduction between each crimping guide plate and the conductive plate in a timely manner. Check whether the connection is good to avoid power outages due to poor conduction and ensure continuous power supply in the IDC computer room used in the power distribution system.

The above is an introduction to connectors, and the following will introduce the plug-in box plugged into the bus duct.

(3) Plug-in box.

Among them, the plug-in box can also be called a power-taking box. It is plugged into the plug-in slot of the bus duct through its plug-in connector to obtain electric energy and transmits it to electrical equipment (such as IDC computer room cabinet) provides power.

It should be pointed out that the bus duct to which the plug-in box is connected may be the bus duct mentioned in (1) above, or other types of bus ducts, which is not limited in this embodiment.

(1) Plug connector 32 of the plug-in box.

Figure 27 is a schematic structural diagram of a plug-in box, including a box 31 and a plug connector 32. Figure 28 is a schematic structural diagram of a plug connector 32. The plug connector 32 includes a plug 320 and a fixing portion 324. As shown in Figure 28 and with reference to Figure 27, the fixing portion 324 of the plug connector 32 is fixed in the box 31, and the plug 320 of the plug connector 32 protrudes from the box 31 to facilitate insertion into the plug slot 111 of the bus duct. catch.

The number of plugs 320 of the plug connector 32 is related to the number of plug slots 111 of the bus duct. For example, if the bus duct includes three plug slots 111, then the plug connector 32 also includes three plugs 320, and each plug 320 Insert into a plug slot 111.

As shown in FIG. 28 , each plug 320 of the plug connector 32 includes an insulating piece 321 and a power-taking blade 322 , and the power-taking blade 322 is located on one side of the insulating piece 321 . The following will first introduce the structural features of the power-taking blade 322, and then introduce the structural features of the insulating member 321.

Referring to FIG. 3 , the power extraction blade 322 has a power connection portion 3221 that protrudes away from the insulating member 321 , and the power connection portion 3221 has a second power connection surface 3222 . In this way, when the plug 320 of the plug connector 32 is inserted into the plug slot 111 of the bus duct, the plug 320 is located in the plug slot 111, and the conductive plate 13 is installed in the plug slot 111, and the first electrical connection of the conductive plate 13 The surface 131 is exposed in the plug-in slot 111, so that the first power connection surface 131 and the second power connection surface 3222 are in contact, thereby realizing the connection between the plug-in box and the busbar duct.

The power-taking blade 322 of the plug connector 32 includes a power connection portion 3221 protruding from the insulator 321, so that when the plug connector 32 is inserted into the bus duct, the power connection portion 3221 can be in close contact with the conductive plate 13 under deformation, thereby achieving Good conduction.

Even if the deformation effect of the power plug 322 becomes poor due to long-term deformation, the plug 320 of the plug connector 32 is also supported by the insulating member 321. Under the support of the insulating member 321, the power plug 322 can still contact with the conductive plate. 13 Maintain good conduction status.

In one example, the plug connector 32 may be a plug connector 32 adapted to the above-mentioned bus duct. Then, the plug slot 111 of the bus duct includes a first plug slot 111A, and is installed in the first plug slot 111A. There are two conductive plates 13. Then, as shown in Figure 28, the plurality of plug connectors 32 may include at least one first plug 320A. Each first plug 320A includes two power-taking blades 322. The two power-taking plugs The pieces 322 are respectively located on opposite sides of the insulating member 321 .

And if the plurality of plug slots 111 also includes a second plug slot 111B, then the plurality of plugs 320 also include at least one second plug 320B, and each second plug 320B includes a power-taking blade 322 to take power. The insert piece 322 is located on one side of the insulating member 321 .

Therefore, if the plurality of plug slots 111 are all first plug slots 111A, then the plurality of plugs 320 are all first plugs 320A. And if the plurality of plug slots 111 include the first plug slot 111A and the second plug slot 111B, then the plurality of plugs 320 include the first plug 320A and the second plug 320B. For example, if the plurality of plug slots 111 includes two first plug slots 111A and one second plug slot 111B, then the plurality of plugs 320 includes two first plugs 320A and one second plug 320B.

Among them, the positions of the first plug 320A and the first plug-in slot 111A correspond to each other, and the positions of the second plug 320B and the second plug-in slot 111B correspond to each other. For example, the first plug 320A is inserted into the first plug-in slot 111A, and the second plug 320A is inserted into the first plug-in slot 111A. The second plug 320B is inserted into the second plug slot 111B.

In another example, the plug connector 32 may not be a plug connector adapted to the above-mentioned bus duct. For example, the plug connector 32 may also be adapted to a bus duct with one slot and one pole, and a bus bar with one slot and one pole. A conductive plate is installed in each plug-in slot of the bus duct. Then, the plurality of plugs 320 are all second plugs 320B.

In this embodiment, the bus duct to which the plug connector 32 is adapted is not specifically limited. In the drawing, the bus duct adapted to the plug connector 32 can be used as an example as shown in FIG. 7 .

Regarding the specific structure of the power-taking insert 322, as shown in Figure 12, the power-taking insert 322 may include a plurality of conductive elastic pieces 3223. The plurality of conductive elastic pieces 3223 are independent of each other and arranged in a comb-tooth shape. Each conductive elastic piece 3223 is Includes power receiving part 3221.

As shown in Figure 29, it is a schematic structural diagram of a single conductive elastic piece 3223. The conductive elastic piece 3223 may include a first inclined piece a1, a flat piece a2 and a second inclined piece a3 connected in sequence. As shown in Figure 28, the first inclined piece a1 Close to the bottom of the plug connector 32 , the second inclined piece a3 is away from the bottom of the plug connector 32 , and the bottom of the plug connector 32 is also close to the box 31 .

As shown in Figures 12 and 29, the first inclined piece a1, the flat piece a2 and the second inclined piece a3 form the above-mentioned power connection part 3221, and the outer end surface of the flat piece a2 (shown by the filled line in Figure 12 surface) to form the second electrical connection surface 3222 described above.

In this way, when the plug connector 32 is inserted into the plug slot 111, the contact portion 3221 of each conductive elastic piece 3223 is squeezed, causing the first inclined piece a1 and the second inclined plane a2 to deform in a flattening tendency, causing the flat piece a2 to The outer end surface of the conductive plate 13 is closely connected to the conductive plate 13, that is, the first electrical connection surface 131 and the second electrical connection surface 3222 are closely connected to each other. Close fit to achieve good conduction.

The power-taking plug-in piece 322 includes a plurality of conductive spring pieces 3223. Then, the number of the conductive spring pieces 3223 can be controlled by the number of the conductive spring pieces 3223 to adapt to the size of the transmitted current. For example, if the current transmitted by the plug connector 32 is relatively large , then the area of the second electrical connection surface 3222 can be increased by increasing the number of conductive elastic pieces 3223 to allow large current to pass.

The power-taking insert 322 includes a plurality of conductive elastic pieces 3223, and these conductive elastic pieces 3223 are independent of each other. Therefore, even if one or some conductive elastic pieces 3223 have poor contact with the conductive plate 13 due to deformation, other conductive elastic pieces 3223 will not be affected. , so that the power-taking insert 322 and the conductive plate 13 still maintain good conduction.

It should be pointed out that the power-taking blade 322 is not a solution that includes multiple conductive elastic pieces 3223. For example, the power-taking blade 322 has an integrally formed sheet structure, so the power-connecting portion 3221 of the power-taking blade 322 can also be It includes the first inclined piece a1, the flat piece a2 and the second inclined piece a3 mentioned above.

The above is an introduction to the structural features of the power-taking blade 322 of the plug connector 32. The structural features of the insulating member 321 of the plug connector 32 will be introduced below.

In one example, the insulation member 321 may include a vertical plate, as shown in FIG. 28 . In another example, the shape of the insulating member 321 can also be arrow-shaped, as shown in Figure 30, including a connected vertical plate 3211 and a guide portion 3212, as shown in Figure 30 and with reference to Figure 31, take the electrical plug. The end of 322 close to the guide part 3212 is received in the space between the bottom of the guide part 3212 and the vertical plate 3211, and the second power connection surface 3222 is located in the space between the bottom of the guide part 3212 and the vertical plate 3211 outside.

As mentioned above, the power-taking insert 322 includes a power connection portion 3221, and the power connection portion 3221 includes a first slant piece, a flat piece and a second slant piece connected in sequence. Then, as shown in Figure 31, the second slant piece The end of a3 away from the flat piece a2 is received in the space between the bottom of the guide part 3212 and the vertical plate 3211, and the outer end surface of the flat piece a2 (that is, the end face away from the vertical plate 3211) is located at the bottom of the guide part 3212 and the space between the vertical plates 3211, where the outer end surface of the flat piece a2 is the second electrical connection surface 3222.

In one example, the end of the second inclined piece a3 away from the flat piece a2 is accommodated in the space between the bottom of the guide part 3212 and the vertical plate 3211 in order to protect the second inclined piece a3 and make the second inclined piece a3 The piece a3 will not tilt away from the vertical plate 3211 during transportation and handling of the plug box. Once the power connection portion 3221 is tilted outward, it will affect the insertion of the plug 320 into the insertion slot 111 .

It can be seen that the guide portion 3212 of the insulating member 321 plays a role in protecting the power plug 322 to prevent power withdrawal. The insert piece 322 is tilted outward.

The above is an introduction to the structural features of the insulating member 321 of the plug 320 .

In one example, in order to improve the safety of the plug connector 32, as shown in Figures 30 and 31, the plug 320 of the plug connector 32 can also include a safety plate 323, which is located away from the insulating piece of the power strip 322. 321 side. For example, for the first plug 320A, since it includes two power-taking blades 322, the number of safety plates 323 is two. One safety plate 323 is located on the side of one power-taking blade 322 away from the insulating member 321, and the other is located on the side of one power-taking blade 322 away from the insulating member 321. A safety plate 323 is located on a side of the other power-taking blade 322 away from the insulating member 321 . For another example, for the second plug 320B, since it includes one power-taking blade 322, the number of safety plates 323 may be one, and the safety plate 323 is located on the side of the power-taking blade 322 away from the insulating member 321. Of course, For the second plug 320B, the number of safety plates 323 may also be two.

Since the safety plate 323 is located on the side of the power strip 322 away from the insulator 321, if the safety plate 323 is too high, it will inevitably interfere with the contact between the power strip 322 and the conductive plate 13 of the bus duct. Therefore, as shown in Figure As shown in FIG. 31 , the height of the safety plate 323 is smaller than the height of the power strip 322 . Referring to FIG. 31 , the height of the safety plate 323 is the length of the safety plate 323 extending from the fixed part 324 , and the height of the power extraction blade 322 is the length of the power extraction blade 322 extending from the fixed part 324 .

In order for the safety plate 323 to play a protective role, correspondingly, the width of the safety plate 323 is greater than or equal to the width of the power strip 322 . Referring to FIG. 30 , the width of the safety plate 323 is the length along the arrangement direction of the plurality of conductive elastic pieces 3223 , and the width of the power extraction piece 322 is also the length along the arrangement direction of the plurality of conductive elastic pieces 3223 . The width of the safety plate 323 is greater than or equal to the width of the power-taking plug-in piece 322, so that the safety plate 323 blocks all the conductive elastic pieces 3223.

Among them, the principle that the safety plate 323 plays a protective role is that when the technician holds the plug-in box and inserts the plug 320 of the plug-in box into the plug slot 111 of the bus duct, his fingers may touch the plug 320 Take out the bottom of the power plug 322 (that is, close to the fixed part 324), and because the bottom of the power plug 322 is blocked by the safety plate 323, the technician's fingers will only touch the safety plate 323, and the safety The plate 323 is insulated so the technician will not get electrocuted.

When the plug connector 32 as shown in Figure 30 is inserted into the bus duct as shown in Figure 7, the outer end surface of the lower groove wall 123 of the phase insulating bracket 12A protrudes from the first contact surface of the phase conductive plate 13A. 131, and the safety plate 323, which can greatly improve the technician's plugging safety and reduce the risk of electric shock.

For example, when the plug connector 32 shown in Figure 30 is first inserted into the bus duct as shown in Figure 7, the outer end surface of the lower groove wall 123 of the phase insulating bracket 12A protrudes from the first end of the phase conductive plate 13A. The power connection surface 131 allows the second power connection surface 3222 of the plug connector 32 to move along the extension surface of the outer end surface of the lower groove wall 123 without contacting the first power connection surface 131 of the phase conductive plate 13A. As long as the If the first power connection surface 131 and the second power connection surface 3222 are not in contact, then the current of the busbar will not flow to the power extraction blade 322 of the plug connector 32. At this time, even if the technician's finger touches the power extraction blade 322, there will be no electric shock. In addition, the bottom of the power extraction plug 322 is blocked by a safety plate 323, and the technician's fingers will not touch the power extraction plug 322. In this way, the outer end surface of the lower groove wall 123 of the phase insulating bracket 12A protrudes from the first contact surface 131 of the phase conductive plate 13A, and the double protection of the plug 320 including the safety plate 323 can greatly reduce the risk of electric shock for technicians. , improve the safety of plugging.

In addition, even if the outer end surface of the lower groove wall 123 of the phase insulating bracket 12A does not protrude from the first contact surface 131 of the phase conductive plate 13A, the safety plate 323 can still be used to prevent the technician's fingers from touching it. The electrical plug 322 can also reduce the risk of electric shock for technicians and improve the safety of plugging.

The above is an introduction to the structure of the plug connector 32 of the plug box. Based on the above, the plug connector 32 at least has the following effects.

The power-taking blade 322 of the plug connector 32 includes a power connection portion 3221 protruding from the insulator 321, so that when the plug connector 32 is inserted into the bus duct, the power connection portion 3221 can be in close contact with the conductive plate 13 under deformation, thereby achieving The connection between the plug-in box and bus duct is good.

The power-taking insert 322 includes a plurality of conductive elastic pieces 3223. Then, the number of the conductive elastic pieces 3223 can be controlled by the number of the conductive elastic pieces 3223 to adapt the size of the transmitted current.

The insulating member 321 includes a guide portion 3212. The guide portion 3212 can protect the power plug 322 and prevent the power plug 322 from tilting outward.

The guide portion 3212 of the insulating member 321 also plays a guiding role when the plug 320 is inserted into the insertion slot 111 to facilitate insertion.

The plug 320 of the plug connector 32 includes a safety plate 323. The safety plate 323 plays a role in blocking the bottom of the power plug 322. The safety plate 323 can be used to prevent the technician's fingers from touching the power plug 322, which can reduce the power consumption. Reduce the risk of electric shock for technicians and improve plugging safety.

As an example, an embodiment of the present disclosure also provides a plug-in box and a plug connector of the plug-in box. Figure 32 is a schematic assembly diagram of a plug-in box provided by an embodiment of the present disclosure. As shown in Figure 32, the plug box includes a plug connector and a box body 31. The box 31 has a first plug-in side opposite to the bus duct, and an installation opening is opened on the first plug-in side. The plug connector is used to be arranged on the first plug side of the plug box and can be plugged into the bus duct to draw power. The plug connector includes a plug 320 .

As shown in FIG. 32 , the plug 320 includes an insulating member 321 and a power extraction blade 322 provided on the insulating member 321 . The upper section of the plug 320 is the plug-in part 201, and the lower section is the connection part 202.

Among them, the wiring part 202 is used to be inserted into the box 31, and the plug-in part 201 is used to be exposed on the first plug-in side and inserted into the bus duct.

The portion of the insulating member 321 corresponding to the wiring portion 202 is fixed to the box 31 , and the portion of the electrical plug 322 corresponding to the wiring portion 202 is used for electrical connection with the circuits in the box 31 . The part of the power-taking insert 322 corresponding to the plug-in part 201 is used for electrical connection with the conductive plate in the bus duct.

The plug connector can be detachably installed on the first plug side, which facilitates modular design of the plug connector. When the plug connector is installed on the box 31, the wiring portion 202 of the plug 320 is inserted into the box 31 to connect the lines, and the plug portion 201 is located outside the box 31 for insertion into the bus duct. The plug 320 includes an insulating member 321 and a power-taking blade 322 arranged on the insulating piece 321. The part of the insulating piece 321 corresponding to the wiring portion 202 is used to be fixed in the box 31 and plays a role in fixing the plug 320. The power-taking blade The part 322 corresponding to the wiring portion 202 is used to connect lines. The portion of the power strip 322 corresponding to the plug portion 201 is used for electrical connection with the conductive plate in the bus duct. The plug connector has a simple structure, and the plug 320 can be assembled on the box 31 as a module, which facilitates separate production and assembly.

Figure 33 is a schematic structural diagram of a plug connector provided by an embodiment of the present disclosure. As shown in FIG. 33 , the plug connector includes a fixing portion 324 and a plurality of plugs 320 .

The fixing portion 324 has a plurality of plug openings 10a on a first side and a wiring opening 10b on a second side.

The structure of the plug 320 is the same as that of the plug 320 in the plug connector shown in FIG. 32 . Figure 34 is a schematic diagram of the assembly structure of the plug connector and the box shown in Figure 33 provided by an embodiment of the present disclosure. As shown in FIG. 34 , the fixing part 324 is used for detachable installation to the first plug side, so that the plug opening 10 a is exposed outside the box 31 , and the wiring opening 10 b is located inside the box 31 .

The plurality of plugs 320 are respectively disposed in the plurality of plug openings 10a, and the plug-in part 201 of each plug 320 is exposed on the first side of the fixing part 324; the wiring part 202 of each plug 320 is inserted and fixed in the fixing part 324, Opposite to the wiring opening 10b.

By providing the plug opening 10a and the wiring opening 10b on the fixed part 324, the plug 320 can be arranged in the plug opening 10a. The plug part 201 of the plug 320 protrudes from the plug opening 10a relative to the fixed part 324. The plug part 201 is used for plugging. After being connected to the bus duct, the connection part 202 of the plug 320 is fixed in the fixing part 324, and the connection part 202 is opposite to the connection opening 10b, thereby facilitating connection. The plug connector has a simple structure, and the plug 320 can be assembled into the fixing part 324 as a module, which facilitates separate production and assembly.

In some examples, the plug connector may not include the fixing part 324 , and the plurality of plugs 320 are installed on the box 31 . Moreover, the plug connector can also be an integral structure with the box body 31, that is, it can be made into a whole body through an integral molding process. For example, it can be made as a whole by injection molding. During injection molding, for example, an insert molding process may be used to injection mold the metal part, such as the power plug 322, and the non-metal part into a whole body.

Figure 35 is a schematic structural diagram of a fixing part provided by an embodiment of the present disclosure. As shown in FIG. 35 , the fixing part 324 includes an upper housing 11 and a lower housing 12 that are detachably connected. The upper housing 11 and the lower housing 12 may be connected by screws, snap-fitted to each other, or may be connected by bonding. In some examples, the fixing part 324 may also be an integral structure, that is, the upper housing 11 and the lower housing 12 are connected as an integral structure.

The plug opening 10a is located on the upper housing 11, and the wiring opening 10b is located on the lower housing 12, specifically, it can be located on the side wall of the lower housing 12.

The number of plug openings 10a can be set according to the number of plugs 320. As an example, the plug connector of the embodiment of the present disclosure includes three plugs 320, and the upper housing 11 has three plug openings 10a.

The number of plugs 320 of the plug connector is related to the number of plug slots of the bus duct. For example, if the bus duct includes three plug slots, then the plug connector includes three plugs 320, and each plug 320 is inserted into a plug slot. In slot 111.

The fixing part 324 may be in the shape of a right prism, and the plug 320 extends from one end of the right prism. Setting the fixing part 324 in the shape of a right prism facilitates the storage and assembly of the plug connector and facilitates modularization.

As shown in FIG. 35 , the outer side wall of the fixing part 324 has a buckle 101 . The buckle 101 is used to detachably install the plug connector in the plug box.

The buckles 101 can be distributed on multiple side walls of the lower housing 12, and can be distributed on different side walls of the lower housing 12. The number of buckles 101 of the cloth can be the same or different. When connecting the plug connector to the box, the lower shell 12 can be directly placed into the corresponding assembly position on the box, and the buckles 101 are used to snap into place with the box. The buckle 101 is easy to connect and facilitates the modularization of the plug connector.

As shown in FIG. 35, the fixing part 324 has a fool-proof structure 11a. The fool-proof structure 11a and the plug opening 10a are located on the same surface of the fixing part 324. The fool-proof structure 11a is provided to prevent the plug connector from being reversed when connected to the bus duct.

In the embodiment of the present disclosure, there are two fool-proof structures 11a, and the two fool-proof structures 11a are respectively provided on opposite sides of the plug opening 10a. Figure 36 is a schematic structural diagram of a plug connector provided by an embodiment of the present disclosure. As shown in Figure 36, the distances between the two fool-proof structures 11a and the plug opening 10a are different.

As an example, the anti-fool structure 11a may be a groove or a protrusion. The embodiment of the present disclosure takes a groove as an example for description. In the disclosed embodiment, the plug opening 10a is located on the upper housing 11, and the anti-fool structure 11a is also located on the upper housing 11. When the plug connector is inserted into the bus duct, the fool-proof structure 11a can prevent the plug connector from being successfully inserted into place when the plug connector is connected reversely. There are protrusions on the bus duct that cooperate with the fool-proof structures 11a. When the plug connector is smoothly connected to the bus duct, the protrusions on the bus duct just snap into the two fool-proof structures 11a. The protrusions on the bus duct may be ridges that are clearance-fitted with the anti-fool structure 11a.

Since the plug opening 10a is located between the two fool-proof structures 11a, and the distances from the two fool-proof structures 11a to the plug opening 10a are different, when the plug connectors are accidentally connected reversely, multiple plugs 320 can be inserted into the bus duct. , but the fool-proof structure 11a cannot face the protrusions on the bus duct, so the protrusions cannot snap into the fool-proof structure 11a, which makes the plug connector unable to be inserted in place to avoid danger caused by incorrect circuit connections.

In some examples, the two foolproof structures 11a are different in size.

Taking the fool-proof structure 11a as a groove as an example, the size of the fool-proof structure 11a may include at least one of the depth and width of the groove. The depth and/or width of the two fool-proof structures 11a are different.

In some examples, the widths of the two foolproof structures 11a may be different. The widths of the protrusions matching the two fool-proof structures 11a are also different, so when the plug connector is inserted into the bus duct, the plug connector is accidentally connected reversely, because the width of the fool-proof structure 11a does not match the width of the protrusions. , so the plug connector cannot be plugged into place, and it can also avoid danger caused by incorrect circuit connection.

In some examples, the depths of the two foolproof structures 11a may be different. The heights of the protrusions matched with the two fool-proof structures 11a are also different. In this way, when the plug connector is inserted into the bus duct, the plug connector is accidentally connected reversely, because the depth of the fool-proof structure 11a does not match the depth of the protrusion. , so the plug connector cannot be plugged into place, and it can also avoid danger caused by incorrect circuit connection.

In other examples, the depth and width of the two fool-proof structures 11 can also be different, which can also avoid dangers caused by incorrect circuit connections.

The plug-in section 211 is located outside the fixing part 324, the wiring fixing section 212 is located inside the fixing part 324, and the wiring fixing section 212 is connected to the fixing part 324.

Optionally, connecting portions 2121 may be connected to both sides of the wiring fixing section 212 , and the connecting portions 2121 are used to connect to the fixing portion 324 . For example, the connecting portion 2121 has a connecting hole, and the connecting portion 2121 is connected to the upper housing 11 through screws.

The power extraction blade 322 includes a power extraction section 221 and a wiring section 222 . The power-taking section 221 is located outside the fixed portion 324, on one side of the plug-in section 211, and opposite to the plug-in section 211. The connection section 222 is located in the fixing portion 324, on one side of the connection fixation section 212, opposite to the connection fixation section 212, and the connection section 222 is connected to the connection fixation section 212.

The plug part 201 of the plug 320 includes a power taking section 221 and a plug section 211 , and the connection part 202 includes a connection section 222 and a connection fixing section 212 .

The wiring section 222 of the power plug 322 is connected to the insulating member 321, and the plug section 211 is used to contact the conductive plate in the bus duct when the plug connector is connected to the bus duct. The wiring section 222 is in the fixing part 324 to connect with the wire introduced through the wiring opening 10b.

Alternatively, the plug 320 may include one or two power extraction blades 322 . When the plug 320 includes two power extraction blades 322 , the two plug connectors 20 are located on opposite sides of the insulator 321 .

Among the plurality of plugs 320 of the plug connector, at least one plug 320 includes two power-taking blades 322. The two power-taking blades 322 are located on opposite sides of the insulating member 321. The two power-taking blades 322 are insulated from each other.

The plug 320, which includes a power extraction blade 322, can be used to make contact with a conductive plate connected to a ground wire in the bus duct.

By disposing power-taking blades 322 on opposite sides of the insulating member 321, the two power-taking blades 322 are insulated, so that the two power-taking blades 322 of one plug 320 can be different from the two power-taking blades 322 in the bus duct. The conductive plates of different phases are in contact, so that one plug 320 can conduct two circuits of electricity of different phases. For example, referring to the plug connector shown in Figure 36, the three plugs from left to right have a total of 5 power-taking blades 322. In order, they can be grounding blades, N-phase blades, L1-phase blades, L-phase blades, and L2-phase blades.

As shown in FIGS. 37 and 38 , the plug 320 also includes a pressing member 23 , and the pressing member 23 includes a pressing plate 231 and a safety plate 323 . The pressing part 23 is an insulating part, that is, made of insulating material.

The pressing plate 231 is located in the fixing portion 324 and is located on the side of the wiring section 222 of the power strip 322 away from the wiring fixing section 212. The pressing plate 231, the wiring section 222 and the wiring fixing section 212 are connected.

Illustratively, the pressing plate 231, the wiring section 222 and the wiring fixing section 212 are connected by bolts. The pressing plate 231 and the wiring fixing section 212 of the insulator 321 clamp the wiring section 222 of the power strip 322 to ensure that the power strip 322 is installed. firm.

The safety plate 323 is located outside the fixed part 324, and is connected to the pressure plate 231. The safety plate 323 is located on the side of the power plug 322 away from the plug section 211 . The safety plate 323 has a height smaller than the height of the power plug 322 and a width greater than or equal to the width of the power plug 322 .

As shown in FIGS. 37 and 38 , the plug 320 further includes a connection terminal 24 , which is located in the fixing portion 324 and on a side of the connection section 222 away from the connection fixation section 212 . The connection terminal 24, the connection section 222 and the connection fixing section 212 are connected, and the connection terminal 24 is opposite to the connection opening 10b.

For example, the connection terminal 24, the connection section 222 and the connection fixing section 212 may be connected by bolts.

The connection terminal 24 is in contact with the connection section 222 of the power plug 322. During connection, the cable extends from the connection opening 10b of the fixation part 324 into the fixation part 324 and is connected to the connection terminal 24.

(2) Locking structure 33 of the plug-in box.

Among them, the locking structure 33 of the plug-in box is used to lock the plug-in box on the shell 11 of the bus duct.

It should be pointed out that the plug-in box in which the locking structure 33 is located may be a plug-in box including the plug connector 32 described in (1) above, or may be other types of plug-in boxes.

In one example, the plug-in box is located in the bus duct only by plugging and unplugging force, and it is difficult to stably connect to the bus duct. Especially in the scenario where the notch of the plug-in slot of the bus duct faces the ground of the IDC computer room, the plug-in box is in the bus duct. The plug-in box of the bus duct can be easily separated from the bus duct. In order to ensure that the plug-in box can be firmly connected to the bus duct after being plugged into the bus duct, accordingly, the plug-in box includes a locking structure 33 .

The number of locking structures 33 included in the plug-in box is mainly related to the size of the plug-in box. For example, if the size of the plug-in box is relatively large or the weight is heavier, then the plug-in box may include more locking structures 33 . The locking structures 33 may include two, three or even four locking structures. If the plug-in box is smaller in size or lighter in weight, the plug-in box may include a locking structure 33 . Among them, this embodiment does not specifically limit the number of locking structures 33 included in the plug-in box. As shown in Figure 41, the plug-in box includes two locking structures 33 as an example. One locking structure 33 is located at At one end of the plug-in box, another locking structure 33 is located at the other end of the plug-in box, and the two locking structures 33 and the plug connector 32 are located on the same side. under The structural features of each locking structure 33 are introduced.

Figure 42 shows a schematic structural diagram of the locking structure 33. The locking structure 33 includes two locking arms 331, a driving member 332 and an unlocking button 333. The lock arm 331 is located in the box body 31 of the plug-in box 3 and has a lock buckle 3311 extending from the box body 31, as shown in Figure 41. The driving member 332 is also located in the box 31 and is linked with the latch arm 331. For example, when the latch arm 331 moves, it can drive the driving member 332 to move, and when the driving member 332 moves, it can also drive the latch arm 331 to move. The unlocking button 333 is used to drive the driving member 332 to move, so that the driving member 332 drives the locking arm 331 to move, unlocking the locking buckle 3311 of the locking arm 331, and pulling out the plug-in box from the bus duct.

Among them, the locking buckles 3311 of the two locking arms 331 can move toward or away from each other, and the locking buckles 3311 are used to engage with the shell 11 of the busbar duct 1 into which the plug-in box 3 is inserted.

For example, when a technician holds the plug-in box and inserts the plug-in box into the bus duct, the two locking buckles 33 move toward each other under the action of external force, thereby entering into the shell 11 of the bus duct. In the card slot, after the locking buckle 3311 is stuck in the card slot of the casing, the two locking buckles 3311 move in the direction away from each other, return to the default state, and are locked in the card slot of the casing 11, and then The plug-in box can be locked in the bus duct by inserting it.

When it is necessary to pull out the plug-in box from the bus duct, the technician can operate the unlocking button 333. The unlocking button 333 drives the locking arm 331 to move through the driving member 332, so that the two locking buckles 3311 move toward each other. At this time, the two locking buckles 3311 are separated from the slots of the housing 11, and the technician can pull out the plug-in box from the bus duct. After pulling out, the technician stops operating the unlocking button 333, and the two locks The stops 3311 move away from each other and return to the default state.

One structural feature of the driving member 332 can be seen in FIG. 42 , including a slide block 3321 and a return spring 3322. The slider 3321 has two strip-shaped through holes 3323. The two strip-shaped through holes 3323 are distributed in a figure-eight shape on the slider 3321. The end of the lock arm 331 has a convex shaft 3312. The convex shafts 3312 of the two locking arms 331 are respectively inserted into the two strip-shaped through holes 3323 of the slider 3321, and the return spring 3322 is located between the two locking arms 331.

Among them, the return spring 3322 is used to restore the two locking buckles 3311 to the default state. When the two locking buckles 3311 are farthest apart, it is the default state.

In this way, as shown in Figure 43, when the two locking buckles 3311 move in the direction of approaching or moving away from each other, the slider 3321 moves in the direction shown by the arrow. When the slider 3321 moves in the direction shown by the arrow, When moving, the two locking buckles 3311 move in the direction of approaching or moving away from each other.

Another structural feature of the driving member 332 can be seen in Figure 44. The driving member 332 is a cam. Both the locking arm 331 and the driving member 332 are rotatably installed in the box 31. The driving member 332 is located on the two locking arms 331. When the driving member 332 rotates, it can drive the lock arms 331 on both sides to rotate.

As shown in Figure 44, the distance between the driving member 332 and the lock arm 331 is relatively close, so that when the driving member 332 rotates, it touches the two lock arms 331, thereby pushing the lock arm 331 to rotate, and the lock arm 331 rotates. When, the two locking buckles 3311 move toward each other, and when the locking arm 331 no longer pushes the locking arm 331 to rotate, the locking arm 331 returns to the default state, then the two locking buckles 3311 move away from each other. direction of movement. Among them, the lock arm 331 can return to the default state under the action of the torsion spring.

Among them, this embodiment does not limit the specific structural features of the driving member 332, as long as it can be linked with the locking arm 331 and can promote the two locking buckles 3311 to move toward or away from each other.

Regarding the unlocking button 333, the unlocking button 333 may be of a push type. When the technician presses the unlocking button 333, the unlocking button 333 triggers the driving member 332 to move, and the driving member 332 drives the two locking buckles 3311 to move toward each other. The unlocking button 333 may also be of a rotary type. When a technician rotates the unlocking button 333, the unlocking button 333 triggers the driving member 332 to move, and the driving member 332 drives the two locking buckles 3311 to move toward each other.

The unlocking button 333 may be located on a side of the box 31 different from the plug connector 32, as shown in FIG. 41 . Generally, technicians will operate the unlocking button 333 when they need to disassemble the plug-in box from the bus duct. Then, the technician holds the plug-in box with both hands and needs to operate the unlocking button 333. Then, the unlocking button 333 can be located on the box. The body 31 is at a position that is easy for technicians to operate. For example, as shown in FIG. 41 , it may be located at the end of the box 31 along the length direction.

In one example, if the plug-in box includes a handle, for example, handles are installed at both ends of the box 31 along the length direction. Since the technician holds the handle, in order to facilitate the operation of the unlock button 333, the unlock button 333 can be located on the handle.

In another example, the box body 31 and the handle of the plug-in box are detachably installed. In this case, the unlocking button 333 may include a first unlocking button and a second unlocking button. The first unlocking button is located on a side of the box 31 side, and the second unlocking button can be located on the handle, and the second unlocking button is used to trigger the first unlocking button.

In this way, the supplier of the plug-in box can process a plurality of boxes including first unlocking buttons and a plurality of handles including second unlocking buttons. If the customer wants a plug-in box without a handle, then the supplier can sell the plug-in box without a handle to the customer, and if the customer wants a plug-in box with a handle, then the supplier can The dealer can install the handle on the box and sell the plug-in box with the handle to the customer. It can be seen that the supplier does not need to process the plug-in box with handles, but obtains the plug-in box with handles through post-assembly. In this way, no matter whether the customer buys a plug-in box with or without a handle, the plug-in box includes an unlocking button used to drive the movement of the driving member.

The above are the structural features of the locking structure 33 of the plug-in box. Based on the above features, the locking structure 33 has at least the following effects.

When the technician inserts the plug-in box into the bus duct, the two locking buckles 3311 of the locking structure 33 can first move toward each other, and then move away from each other, thereby getting stuck on the casing of the bus duct. , so that the plug-in box can be locked on the bus duct after being inserted into the bus duct, which facilitates the insertion of the plug-in box.

When the technician pulls out the plug-in box from the bus duct, the technician operates the unlocking button to move the two locking buckles 3311 toward each other. The technician pulls out the plug-in box to remove the plug-in box from the bus duct. Pull out from the slot, easy to operate.
