The embodiment of the disclosure provides a bus duct, which is applied to a power distribution system. The bus duct is a large-current transmission device formed by using a metal plate such as a copper plate or an aluminum plate as a conductor plate, using an insulating material as a support and matching a metal shell, and has increasingly replaced cables in the project of power transmission trunk lines. Assorted, distribution system includes the jack box, and the jack box also can be called the electricity box of getting for peg graft in the bus duct, get the electricity from in.

For example, a power distribution system including a bus duct may be applied to an Internet Data Center (IDC for short), and specifically, the bus duct may be disposed in a machine room of the IDC, and external power distribution (such as commercial power and a storage battery) is introduced into the IDC machine room and then is connected to the bus duct. The jack box is inserted into the bus duct to take power from the bus duct, the jack box comprises a power transmission port, and the cable is inserted into the power transmission port of the jack box and led into each cabinet (such as each column head cabinet) in the IDC machine room to supply power to each cabinet.

The bus duct will be further described below.

Fig. 1 is a schematic structural diagram of a bus duct, and referring to fig. 1, in this embodiment, the bus duct includes: the housing 110 has a plurality of insertion grooves 111 distributed along a length direction, and notches of the plurality of insertion grooves 111 are located on the same side of the housing 110.

Fig. 2 is a sectional view of a bus duct, and referring to fig. 2, in this embodiment, the conductive plate 120 is located in the plug slot 111, and the conductive plate 120 is insulated from the housing 110, and the conductive plate 120 has a power receiving surface 121 for contacting with the conductive portion 220 of the plug box. The insertion groove 111 has two conductive plates 120 therein, and the polarities of the two conductive plates 120 are different from each other.

The housing 110 has an insertion groove 111 at one side thereof for receiving the conductive plate 120 and providing a mounting base for the conductive plate 120. The conductive plate 120 is installed in the insertion groove 111, the conductive plate 120 is insulated from the housing 110, so that the power utilization safety is ensured, the conductive plate 120 is provided with the power connection surface 121, and the power connection surface 121 is exposed in the insertion groove 111 and is used for contacting with the conductive part 220 of the insertion connector 210 of the insertion box 20, so that the electric connection between the bus duct and the insertion box 20 is realized. Since the insertion groove 111 has two conductive plates 120 and the polarities of the two conductive plates 120 are different from each other, when one insertion connector 210 is inserted into one insertion groove 111, the insertion connector 210 can be electrically connected to the two polarities respectively (see fig. 3). Therefore, the number of the inserting grooves 111 is effectively reduced, the structure of the bus duct is simpler, and the miniaturization design of the bus duct is facilitated.

In addition, after the plug 210 of the jack box 20 is plugged into the jack groove 111 along the depth direction of the jack groove 111, the conductive part 220 of the plug 210 can contact with the power connection surface 121 of the conductive plate 120, and the bus duct and the jack box 20 can be quickly and electrically connected without other operations.

In an application, one side that the notch of jack box 111 was located is the grafting side of bus duct, one side of bus duct back to the grafting side is the installation side, the top at the IDC computer lab can be installed to the installation side of bus duct, the jack box 111 of bus duct is towards the ground of IDC computer lab, the jack box 20 can be handed to the technical staff, insert jack plug 210 of jack box 20 to the bus duct, for example, insert jack plug 210 one by one to the jack box 111 of bus duct, thereby realize the electricity of jack box 20 in the bus duct getting.

In this embodiment, the bus duct may be a small bus duct, that is, a bus duct in which the transmitted current is within 800A. Certainly, the bus duct can also be a large bus duct, and the specific type of the bus duct is not limited in the embodiment of the application.

As can be seen from the foregoing, the arrangement of the conductive plates 120 in the insertion slots 111 is a key to realize "one slot and two poles" of the bus duct. The arrangement of the conductive plates 120 will be described below.

Referring to fig. 2, in the present embodiment, the plurality of insertion grooves 111 includes at least one first insertion groove 1111, the first insertion groove 1111 has two conductive plates 120 therein, the two conductive plates 120 are respectively located at two groove walls of the first insertion groove 1111 that are opposite to each other, and the two conductive plates 120 are opposite to each other and have a distance therebetween.

In the above implementation, the first mating groove 1111 is a kind of the mating groove 111. The first mating slot 1111 corresponds to the second and third mating slots 111, counted from left to right in fig. 2. In the first inserting groove 1111, there are two conductive plates 120, and the power connection surfaces 121 of the two conductive plates 120 are arranged at an interval and can be respectively contacted with the conductive part 220 of the inserting head 210, thereby realizing "one groove with two poles", and making the structure of the bus duct more compact.

With reference to fig. 2, in the present embodiment, the plurality of insertion grooves 111 further includes a second insertion groove 1112, the second insertion groove 1112 has a conductive plate 120 therein, the conductive plate 120 is located at one groove wall of the second insertion groove 1112, and the conductive plate 120 is opposite to another groove wall of the second insertion groove 1112 and has a distance therebetween.

In the above implementation, the second insertion groove 1112 is another kind of the insertion groove 111. The second mating groove 1112 corresponds to the first mating groove 111 from left to right in fig. 2. In the second insertion groove 1112, there is a conductive plate 120, and the contact surface 121 of the conductive plate 120 is arranged opposite to the groove wall of the insertion groove 111 at a distance and can contact the conductive part 220 of the insertion head 210.

That is, the insertion groove 111 has two kinds, one kind is the first insertion groove 1111 having two conductive plates 120 therein, and the other kind is the second insertion groove 1112 having one conductive plate 120 therein. The selection of the kind of the inserting groove 111 is related to the number of the conductive plates 120 of the bus duct. A classification discussion follows.

If the number of the conductive plates 120 of the bus duct is even, all the insertion grooves 111 may be the first insertion grooves 1111, or some of the insertion grooves 111 may be the first insertion grooves 1111 and the remaining even insertion grooves 111 may be the second insertion grooves 1112.

If the number of the conductive plates 120 of the bus duct is odd, the plurality of inserting grooves 111 includes both the first inserting groove 1111 and the second inserting groove 1112. For example, the number of the second insertion grooves 1112 is one, and the rest are the first insertion grooves 1111.

Further, the number of conductive plates 120 is related to the system of the power distribution system. Illustratively, the conductive plate 120 is a copper plate for transmitting power. For example, if the power distribution system is a three-phase five-wire system, the bus duct includes five conductive plates 120, and the five conductive plates 120 correspond to three phase lines, a neutral line, and a ground line, respectively. If the power distribution system is a three-phase four-wire system, the bus duct includes four conductive plates 120, and the four conductive plates 120 correspond to three phase lines and one zero line, or three phase lines and one ground line, respectively.

In this embodiment, if the power distribution system is a three-phase five-wire system, the bus duct includes five conductive plates 120, that is, the number of the conductive plates 120 is an odd number. In this case, the insertion groove 111 includes two first insertion grooves 1111 and one second insertion groove 1112, in which the two first insertion grooves 1111 accommodate the conductive plate 120 (phase conductive plate) corresponding to the three phase lines and the conductive plate 120 (neutral conductive plate) corresponding to the neutral line, respectively, and the one second insertion groove 1112 accommodates the conductive plate 120 (ground conductive plate) corresponding to the ground line. If the power distribution system is a three-phase four-wire system, the bus duct includes four conductive plates 120, i.e., the number of conductive plates 120 is even. In this case, the insertion groove 111 includes two first insertion grooves 1111 for receiving the conductive plates 120 corresponding to the three phase wires and the conductive plate 120 corresponding to the neutral wire, respectively.

Of course, the arrangement of the conductive plates 120 is only an example, and the disclosure is not limited thereto.

Illustratively, the spacing between two conductive plates 120 in the first mating slot 1111 is less than or equal to 12.5 millimeters.

In the above implementation, the distance d1 between the power connection surfaces 121 of the two conductive plates 120 in the first inserting groove 1111 is less than or equal to 12.5 mm, so that the bus duct can meet the IP2X standard, and the hand of a technician is prevented from extending into the distance d1 to cause electric shock.

Illustratively, the spacing between the conductive plate 120 in the second mating groove 1112 and the opposing groove wall is less than or equal to 12.5 millimeters.

In the above implementation, a distance d2 between the power connection surface 121 of the conductive plate 120 in the second inserting groove 1112 and the opposite groove wall is less than or equal to 12.5 mm, so that the bus duct can meet the IP2X standard, and a hand of a technician is prevented from extending into the distance d2 to cause an electric shock.

Note that, if the conductive plate in the second insertion groove 1112 is a ground conductive plate, the distance d2 between the conductive plate 120 and the groove wall of the insertion groove 111 is not limited, because a technician does not get an electric shock even if the technician's hand is inserted.

With continued reference to fig. 2, in this embodiment, the bus duct further includes an insulating support 130, the insulating support 130 is located in the insertion groove 111, and a length direction of the insulating support 130 is consistent with a length direction of a groove wall of the insertion groove 111. The conductive plate 120 is located in the insulating support 130, and the contact surface 121 of the conductive plate 120 is exposed in the insertion groove 111.

In the above implementation, the insulating bracket 130 is mounted in the insertion groove 111 to provide a mounting base for the conductive plate 120, and the conductive plate 120 is mounted on the insulating bracket 130 to achieve the insulating mounting between the conductive plate 120 and the housing 110.

Illustratively, the insulating support 130 and the conductive plate 120 are both long, the conductive plate 120 is located in the insulating support 130, and the insulating support 130 semi-wraps the conductive plate 120, so that the conductive plate 120 has a power connection surface 121 exposed in the plug slot 111 to be in contact with the conductive portion 220 of the plug box 20 for conduction.

It should be noted that, since the insulating supports 130 are used for realizing the insulating installation of the conductive plates 120 in the insertion grooves 111, the number of the insulating supports 130 is the same as that of the conductive plates 120. That is, the number of the insulation brackets 130 in the first insertion groove 1111 is two, and the number of the insulation brackets 130 in the second insertion groove 1112 is one.

With continued reference to fig. 2, in the present embodiment, the insulating support 130 has an accommodating through slot 131 extending along the length direction thereof, and the notch of the accommodating through slot 131 is located in the inserting slot 111. The conductive plate 120 is located in the receiving through slot 131, and the power connection surface 121 of the conductive plate 120 is exposed in the insertion slot 111 through the slot opening of the receiving through slot 131.

In the above implementation manner, the insulating support 130 has an accommodating through groove 131, the accommodating through groove 131 is used for providing an installation space for the conductive plate 120, the conductive plate 120 is inserted into the accommodating through groove 131, and the connection surface 121 is exposed in the insertion groove 111, so that the insulating installation between the conductive plate 120 and the housing 110 is realized, and the power utilization safety is ensured.

In the present embodiment, the slot wall of the receiving through slot 131 has a protruding seam 132, the protruding seam 132 protrudes from the slot wall of the receiving through slot 131, and the protruding seam 132 is located at the slot opening of the receiving through slot 131. The contact surface 121 of the conductive plate 120 has a female spigot 122, and the female spigot 122 and the male spigot 132 are inserted together.

In the present embodiment, the male and

female spigots

132 and 122 can be mutually matched, so that the conductive plate 120 is clamped in the receiving through slot 131, thereby realizing a stable installation between the conductive plate 120 and the insulating bracket 130.

Fig. 4 is a sectional view of the bus duct, and fig. 4 differs from fig. 2 mainly in the structure related to the conductive plate 120. Referring to fig. 4, in the present embodiment, one side of the conductive plate 120 has an electric contact spring 123. One end of the electric contact spring 123 extends away from the conductive plate 120, and one side of the electric contact spring 123 away from the conductive plate 120 is an electric contact surface 121.

In the above implementation, the electrical contact spring 123 is connected to the conductive plate 120. When the plug 210 of the jack box 20 is plugged into the plug groove 111, the plug 210 of the jack box 20 can press the electric connection elastic sheet 123, so that the electric connection elastic sheet 123 is elastically deformed and is pressed on the conductive part 220 of the plug 210, and then the stable contact between the electric connection surface 121 on the electric connection elastic sheet 123 and the plug 210 is realized, and the stable electric connection between the bus duct and the jack box 20 is improved.

Illustratively, while the end of the power spring tab 123 extends away from the conductive plate 120, it also extends away from the slot of the insertion slot 111. Due to the design, the stroke of inserting the plug 210 into the insertion slot 111 can be increased, so that premature power connection of the plug 210 in the process of inserting the plug into the insertion slot 111 is avoided.

Fig. 5 is a sectional view of the bus duct, and fig. 5 is different from fig. 2 mainly in the structure of the conductive plate 120. Referring to fig. 5, in the present embodiment, one side surface of the conductive plate 120 has an electrical connection protrusion 124. The electrical connection protrusion 124 protrudes away from the conductive plate 120, and a side of the electrical connection protrusion 124 away from the conductive plate 120 is an electrical connection surface 121.

In the above implementation, the electrical connection bump 124 is connected to the conductive plate 120. When the plug 210 of the jack box 20 is plugged into the plug groove 111, the plug 210 of the jack box 20 and the power connection protrusion 124 are pressed against each other, so that the plug 210 and the power connection protrusion are tightly attached to each other, the power connection surface 121 on the power connection elastic sheet 123 is stably contacted with the plug 210, and the stable electric connection between the bus duct and the jack box 20 is improved.

With reference to fig. 5, in the present embodiment, when the conductive plate 120 is a ground conductive plate, the distance between the electrical connection protrusion 124 and the slot opening of the insertion slot 111 is a first distance d3. When the conductive plate 120 is a phase conductive plate or a neutral conductive plate, the distance between the electrical connection protrusion 124 and the slot opening of the insertion slot 111 is a second distance d4, and the first distance d3 is smaller than the second distance d4.

In the above implementation, since the first distance d3 is smaller than the second distance d4, during the process of plugging the plug 210 into the plugging slot 111, the conductive part 220 of the plug 210 contacts the electrical connection protrusion 124 of the ground conductive plate first, and as the plug 210 moves, the conductive part 220 of the plug 210 will contact the electrical connection protrusion 124 of the phase conductive plate or the neutral conductive plate later. In this way, the preferential grounding of the plug 210 can be realized, and the safety standard of the ground-first conduction can be satisfied.

It should be noted that the first distance d3 and the second distance d4 can be determined by the relative position of the electrical connection protrusion 124 on the conductive plate 120. For example, the electrical connection protrusion 124 is close to the slot of the insertion slot 111, such that the first distance d3 is smaller, and conversely, the first distance d3 is larger, and the second distance d4 is the same. In addition, the first distance d3 and the second distance d4 may be determined by the relative position between the conductive plate 120 and the slot opening of the insertion slot 111. For example, the conductive plate 120 is close to the opening of the insertion slot 111, such that the first distance d3 is smaller, and conversely, the first distance d3 is larger, and the second distance d4 is the same.

Fig. 6 is a sectional view of the bus duct, and fig. 6 mainly differs from fig. 2 in that the bus duct further includes a dust cover 140, and the dust cover 140 is located at the notch of the plug-in slot 111 and covers the notch of the plug-in slot 111.

The dustproof cover 140 covers the insertion groove 111, so that sundries can be effectively prevented from entering the insertion groove 111 from the notch of the insertion groove 111. It will be readily appreciated that although the dust cap 140 is disposed at the slot of the jack slot 111, the dust cap 140 should not interfere with the plugging of the plug connectors 210 of the jack box 20.

In this embodiment, this bus duct not only can be used to carry electric power, can also be used to hold additional pencil, such as weak wire, net twine. Referring to fig. 2, the housing 110 further has an additional slot 112 along the length direction, and the slot opening of the additional slot 112 is located at one side of the housing 110 along the length direction and is different from the slot opening of the insertion slot 111.

In the above implementation, the notch of the additional slot 112 is located at one side of the housing 110 in the length direction, and is located at a different side from the notch of the insertion slot 111. This is because the side of the notch of the additional slot 112 is different from the side of the notch of the insertion slot 111 so as not to affect the insertion of the plug 210 because the notch of the insertion slot 111 is used for the insertion of the plug 210 of the insertion box 20.

For example, the bus duct is suspended on top of the IDC room, then the slot opening 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 located on the upper side facing the ceiling, and the slot opening of the additional slot 112 is located on the left or right side of the bus duct.

In one example, to close the additional slot 112, the housing 110 further includes an additional slot cover 113, and the additional slot cover 113 covers the slot opening of the additional slot 112, for example, the slot opening of the additional slot 112 can be covered by a snap-fit manner.

In one example, in order to allow the additional wire harness to be introduced into the additional groove 112 and to pass out of the additional groove 112, a gap is formed between the additional groove 112 and the additional groove cover 113 to allow the additional wire harness to pass through.
