The bus bar plugging structure will be further described below.
Fig. 1 is a schematic structural diagram of a bus duct 10, and referring to fig. 1, in this embodiment, the bus duct 10 includes a housing 110, a conductive plate 120, and an insulating support 130, where the housing 110 has a plurality of insertion grooves 111 extending along a length direction, the plurality of insertion grooves 111 are arranged at intervals, notches of the plurality of insertion grooves 111 are located on the same side of the housing 110, and the insulating support 130 is located in the insertion groove 111, and the length direction is the same as the length direction of a groove wall of the insertion groove 111.
Fig. 2 is a schematic cross-sectional view of a bus duct, and with reference to fig. 2, in this embodiment, the insulating support 130 has an accommodating through groove 131 extending along a length direction thereof, a notch of the accommodating through groove 131 is located in the insertion groove 111, a protrusion 132 is located at a notch of a part of the accommodating through groove 131, the protrusion 132 is close to the notch of the insertion groove 111, the conductive plate 120 is located in the accommodating through groove 131, the conductive plate 120 has a first power connection surface 121 exposed in the insertion groove 111, and the first power connection surface 121 does not protrude from the notch of the accommodating through groove 131.
Fig. 3 is a schematic structural diagram of the plug 20, and referring to fig. 3, in this embodiment, the plug 20 includes an insulating plate 210 and a conductive part 220, the conductive part 220 is located on one side of the insulating plate 210, the conductive part 220 has an electrical connection part 221 facing away from a protrusion 132 of the insulating plate 210, the electrical connection part 221 has a second electrical connection surface 222, and the plug 20 plugged into the plug slot 111 can pass over the protrusion 132 to make the first electrical connection surface 121 and the second electrical connection surface 222 electrically contact.
Fig. 4 is a schematic illustration of the plugging between the bus duct 10 and the plug 20, and referring to fig. 4, in this embodiment, the housing has a plurality of plugging grooves for accommodating the insulating support and the conductive plate and providing a mounting base for the insulating support. The insulating support is provided with an accommodating through groove 131, the conductive plate is inserted into the accommodating through groove 131, and the first electric connection surface is exposed in the insertion groove, so that the insulating installation between the conductive plate and the shell is realized, and the power utilization safety is ensured. The protrusion 132 is formed at the notch of one part of the receiving through groove 131, and the protrusion 132 is not formed at the notch of the other part of the receiving through groove 131. The plug comprises an insulating plate and a conductive part, wherein the insulating plate is used for providing a mounting base for the conductive part. The conductive part is provided with an electric connection part, the electric connection part protrudes 132 towards the direction far away from the insulating plate, and the conductive part is provided with a second electric connection surface. In the process of inserting the plug into the insertion groove, a part of the second electrical connection surface of the electrical connection part directly crosses the notch of the accommodating through groove 131 without the protrusion 132 and contacts the first electrical connection surface of the conductive plate in the accommodating through groove 131 first, so as to realize electrical connection between the conductive part and the conductive plate. Meanwhile, the second contact surface of another part of the electrical connection part is pushed up by the protrusion 132 and cannot contact the first contact surface of the conductive plate received in the through slot 131 (see the upper part of fig. 4). As the plug connector continues to move into the plug slot, the second electrical contact surface of the electrical contact portion pushed up by the protrusion 132 will pass over the protrusion 132 and contact the first electrical contact surface of the conductive plate in the accommodating through slot 131, so as to achieve electrical connection between the conductive portion and the conductive plate (see the lower part of fig. 4).
That is, by having the protrusion 132 at the notch of one part of the accommodating through slot 131 and not having the protrusion 132 at the notch of the other part of the accommodating through slot 131, one part of the conductive part is electrically connected to the corresponding conductive plate first, and the other part of the conductive part moves along with the continuous plugging of the plug, and then is electrically connected to the conductive plate. Therefore, the current-conducting plate which is electrically connected firstly is set as the ground wire current-conducting plate, so that the plug connector can be grounded firstly, and the electricity utilization safety is further improved.
In addition, since the conductive plate 120 and the electrical connection part 221 are in surface contact with each other via the first electrical connection surface 121 and the second electrical connection surface 222, the insertion stability between the bus duct 10 and the plug 20 can be improved.
In one application, one side of the bus duct 10 is a plugging side, and the opening of the plugging groove 111 is located at the plugging side. One side of bus duct 10 back to the grafting side is the installation side, and the top in the IDC computer lab can be installed to the installation side of bus duct 10, and the inserting groove 111 of bus duct 10 is towards the ground of IDC computer lab, and the jack box can be handed to the technical staff, inserts the plug 20 of jack box to bus duct 10, for example, insert plug 230 of plug 20 to the inserting groove 111 of bus duct 10 one by one to realize the electricity of jack box in bus duct 10 and get.
In this embodiment, the bus duct 10 may be a bus duct drop 10, and the bus duct drop 10 is also a bus duct drop 10 whose transmitted current is within 800A. Certainly, the bus duct 10 can also be a large bus duct 10, and the specific type of the bus duct 10 is not limited in the embodiment of the present application.
It should be noted that each insertion groove 111 has a conductive plate 120 therein. The plug 20 includes a plurality of plugs 230, and each plug 230 includes an insulating plate 210 and a conductive part 220.
Illustratively, the number of plugs 230 is the same as the number of the plugging slots 111 of the bus duct 10, for example, if the number of the plugging slots 111 is three, then the number of the plugs 230 is also three, and the plugging slots 111 and the plugs 230 are in one-to-one correspondence. Of course, the number of the plugs 230 and the slots 111 is not limited in the embodiments of the present disclosure.
As can be seen from the foregoing, the provision of the protrusion 132 at the notch of one part of the accommodating through slot 131, and the absence of the protrusion 132 at the notch of the other part of the accommodating through slot 131 are key points for improving the electrical safety. The protrusions 132 will be described below.
Referring to fig. 2 again, in the present embodiment, the protrusion 132 has a slope 133, the slope 133 is inclined to protrude from the insulating holder 130 in a direction inward from the opening of the insertion slot 111, and the slope 133 is in sliding contact with the second contact surface 222.
During the process of plugging the plug 20 into the bus duct 10, the electrical connection part 221 contacts with the protrusion 132, and as the plug 20 is plugged, the second electrical connection surface 222 of the electrical connection part 221 slides to contact with the inclined surface 133 and gradually moves away from the insulating support 130 under the action of the inclined surface 133 until the second electrical connection surface crosses over the protrusion 132. That is, the second contact surface 222 of the electrical contact part 221 can easily pass over the protrusion 132 by the slope 133, and interference between the electrical contact part 221 and the protrusion 132 is prevented.
In this embodiment, the protrusion 132 is located on the insulating support 130, and can be an integrated structure with the insulating support 130. The insulating bracket 130 is connected with the wall of the insertion groove 111, and the notch of the accommodating through groove 131 of the insulating bracket 130 faces the other side wall opposite to the insertion groove 111. The first power receiving surface 121 of the conductive plate 120 is exposed in the insertion groove 111 through the notch of the receiving through groove 131.
In the above implementation manner, one side of the insulating support 130 is connected to a groove wall of the insertion groove 111, the other side of the insulating support 130 has an accommodating through groove 131, and the conductive plate 120 is inserted into the accommodating through groove 131, and a notch of the accommodating through groove 131 is used as a passage for exposing the first connection surface 121 in the insertion groove 111.
Illustratively, the insulating support 130 has a mounting through groove 134 extending along the length direction thereof, the wall of the insertion groove 111 has a mounting insert 112 extending along the length direction thereof, and the mounting insert 112 is inserted into the mounting through groove 134.
Through the cooperation between the installation through groove 134 and the installation inserting strip 112, the insulation support 130 can be stably clamped in the inserting groove 111, so that the stable installation of the conductive plate 120 in the inserting groove 111 is ensured.
It should be noted that both ends of the accommodating through groove 131 and the mounting through groove 134 penetrate both ends of the insulating bracket 130 in the length direction. As such, the conductive plate can be inserted into the receiving through groove 131 from one end of the receiving through groove 131, and the mounting sleeve can be inserted into the mounting through groove 134 from one end of the mounting through groove 134.
According to the above, the current-conducting plate which is electrically connected firstly is set as the ground wire current-conducting plate, so that the plug connector can be grounded firstly, and the electricity utilization safety is further improved. The leading ground will be described below with reference to the connection mode of the bus duct 10.
In this embodiment, the insulating support 130 and the conductive plate 120 are both in a long shape, 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 the first power connection surface 121 exposed in the inserting groove 111, so as to be in contact with the second power connection surface 222 of the inserting box for conduction.
Illustratively, the conductive plate 120 is a copper plate for transmitting electricity. The number of conductive plates 120 corresponds to the standard of the power distribution system. For example, if the power distribution system is a three-phase five-wire system, the bus duct 10 includes five conductive plates 120, and the five conductive plates 120 correspond to three phase lines, one neutral line, and one ground line, respectively.
Referring to fig. 2 again, in the present embodiment, the plurality of inserting grooves 111 includes at least one first inserting groove 1111, two insulating brackets 130 are installed in the first inserting groove 1111, and the two insulating brackets 130 are respectively located at two groove walls of the first inserting groove 1111 that are opposite to each other, the first connecting surfaces 121 of the conductive plates 120 in the two insulating brackets 130 are opposite to each other and have a distance therebetween, and the notches of the accommodating through grooves 131 of the two insulating brackets 130 have protrusions 132.
In the above implementation, the first mating groove 1111 is a kind of the mating groove 111. The first docking slot 1111 corresponds to the second and third docking slots 111 from left to right in fig. 2. In the first inserting groove 1111, there are two insulating supports 130, and there are two corresponding conductive plates 120, and the first power connection surfaces 121 of the two conductive plates 120 are arranged at an interval and can be contacted with two different second power connection surfaces 222, respectively, so that the structure of the bus duct 10 is more compact.
In this embodiment, the plurality of inserting grooves 111 further includes a second inserting groove 1112, an insulating support 130 is installed in the second inserting groove 1112, the insulating support 130 is located at one groove wall of the second inserting groove 1112, the first power connection surface 121 of the conductive plate 120 in the insulating support 130 is opposite to the other groove wall of the second inserting groove 1112 and has a distance therebetween, and a groove opening of the insulating support 130, which receives the through groove 131, is a plane or a recess, that is, does not have the protrusion 132.
In the above implementation, the second mating groove 1112 is another type of mating groove 111. The second mating groove 1112 corresponds to the first mating groove 111 from left to right in FIG. 2. In the second plug groove 1112, there is an insulating holder 130, which correspondingly has a conductive plate 120, and the first contact surface 121 of the conductive plate 120 is spaced apart from the groove wall of the plug groove 111 and can be contacted with a second contact surface 222. Since only one conductive plate 120 is present in the plug-in groove 111, the connection between the first contact surface 121 and the second contact surface 222 is more reliable.
Illustratively, the bus duct 10 is a three-phase five-wire bus duct, the plurality of conductive plates 120 includes a phase conductive plate 122 and a ground conductive plate 123, the phase conductive plate 122 is located in the first insertion groove 1111, and the ground conductive plate 123 is located in the second insertion groove 1112.
In the above implementation, the phase conductive plate 122 is connected to the phase line, and the ground conductive plate 123 is connected to the ground line. In the process of inserting the plug 20 into the bus duct 10, the ground conductive plate 123 first contacts with the corresponding electrical connection part 221 under the action of the protrusion 132, and the current can be guided to the ground through the ground conductive plate 123, which is safe for technicians. Subsequently, the phase conductive plate 122 is contacted with the corresponding power connection part 221, so that the plug connector 20 can take power on the bus duct 10.
Fig. 5 is a schematic structural diagram of the plug 20, and fig. 5 omits a portion of the insulating plate 210 to better show the conductive portion 220 compared to fig. 2. Referring to fig. 5, in the present embodiment, the first end of the conductive part 220 is connected to the insulating plate 210, the second end of the conductive part 220 is suspended and spaced apart from the insulating plate 210, and the electrical connecting part 221 is close to the second end of the conductive part 220, so that the electrical connecting part 221 can move toward the insulating plate 210 under the action of the protrusion 132. The conductive portion 220 has a concave section 223 near the first end, the concave section 223 is concave toward the insulating plate 210, the first contact surface 121 and the second contact surface 222 are electrically contacted after the electrical connection portion 221 passes over the protrusion 132, and the concave section 223 receives the protrusion 132.
In the above implementation, the insulating plate 210 provides a mounting base for the first end of the conductive part 220, and the second end of the insulating plate 210 is suspended. Because the electric connection part 221 is close to the second end of the conductive part 220, the electric connection part 221 can elastically swing along with the second end of the conductive part 220 on the basis of the first end of the conductive part 220, and then the second electric connection surface 222 on the electric connection part 221 can be tightly attached to the first electric connection surface 121, thereby ensuring reliable connection. Further, the electric connection part 221 can adaptively swing along with the second end of the conductive part 220 in the process that the electric connection part 221 passes over the protrusion 132. After the electric connection part 221 passes over the protrusion 132, the concave section 223 can accommodate the protrusion 132, that is, the protrusion 132 no longer pushes against the conductive part 220, so that the conductive part 220 can drive the electric connection part 221 to move away from the insulating plate 210 under the action of its own elasticity, and further the first electric connection surface 121 and the second electric connection surface 222 can be electrically contacted.
Fig. 6 is a schematic structural diagram of the conductive portion 220, and in the present embodiment, in combination with fig. 6, the electrical connection portion 221 includes a first inclined piece 2211, a flat piece 2212 and a second inclined piece 2213 which are connected in sequence. The ends of the first slanted piece 2211 and the second slanted piece 2213 connected to the flat piece 2212 protrude out of the insulating plate 210, so that the flat piece 2212 is spaced from the insulating plate 210, and the side of the flat piece 2212 facing away from the insulating plate 210 is the second contact surface 222 (the surface indicated by the filling line in fig. 6).
In the above implementation, when the plug 20 is inserted into the plug slot 111, the electrical connection part 221 is pressed, so that the first inclined sheet 2211 and the second inclined surface 133 deform in a flattening trend, and the flat sheet 2212 is urged to be tightly attached to the conductive plate 120, that is, the first electrical connection surface 121 and the second electrical connection surface 222 are tightly attached to each other, thereby achieving a stable connection between the conductive part 220 and the conductive plate 120.
