Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a busbar bridge used for switch cabinet wiring. Background Art

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all walks of life has increased rapidly. Bus bridges are widely used as a means of transmitting large currents. Bus bridges are a new type of distribution conductor and are mostly found in high-rise buildings and large workshops.

[0003] Publication No. CN216289535U discloses a new busbar bridge for high-voltage switchgear, including an end cover, a frame, a through hole and a positioning mechanism. The utility model sets a positioning mechanism at the bottom of the end cover. After the cable passes through the through hole and enters the inner side of the slot, the end cover drives the convex plate and the plug plate to be placed in the frame. At the same time, the plug plate enters the inner side of the slot, so that the receiving groove and the two rubber sheets in the slot cooperate to clamp and fix the cable. At the same time, the clamping rod is subjected to the elastic force of the spring to enter the inner side of the clamping slot in the frame to fix it. The position of the end cover and the plug plate is fixed, which achieves the beneficial effect of quickly installing the busbar bridge and improving work efficiency; the busbar bridge in the above technology pushes the rotating rod downward and rotates, driving the cam to push the fixing ring and other parts to realize the disassembly and separation of the end cover and the frame, but the frame is an integrated structure, and the maintenance range is limited. When the depth is deep, the maintenance personnel need to manually explore the deeper interior of the busbar bridge for maintenance, which increases the personal safety of the maintenance personnel and increases the difficulty of maintenance for the maintenance personnel, so further improvement is needed.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a busbar bridge for switch cabinet wiring, comprising a horn cover and a supporting cover, wherein raised strips are installed on both sides of the inside of the horn cover, and support blocks are installed on both sides of the raised strips, the inside of one end of the support block is connected to a spring limiting column, and one end of the spring limiting column is connected to a guide bar, the bottom end of the guide bar is provided with a groove, the guide bar is installed at one end of the busbar bridge body, and the busbar bridge body is slidably installed at the bottom end of the horn cover, a protective cover is installed inside the supporting cover, and a conductive sheet is provided inside the protective cover.

[0006] When using a busbar bridge for switch cabinet wiring using the present technical solution, the protective cover is bonded to the supporting cover, and the busbar bridge body is fixedly installed on the supporting cover by bolts, and then the raised strips are slid in the guide rails, and the support blocks and spring limit columns are used to achieve a fixed connection between the horn cover and the busbar bridge body, and then the assembled busbar bridge is installed on the switch cabinet, and then multiple cables are passed through the through holes on the conductive sheet to realize the parallel use of multiple cables.

[0007] Preferably, the raised strip slides inside the guide rail, and the horn cover is slidably connected to the busbar bridge body through the raised strip and the guide rail.

[0008] Preferably, four groups of spring limiting columns are provided, which are evenly installed at one end of the guide rail and correspond one to one with the positions of the support blocks.

[0009] Preferably, the groove is arranged inside the guide rail, with one end being an opening and the other end being a closed opening.

[0010] Preferably, the conductive sheet is made of copper core material, and there are multiple groups of conductive sheets. There are multiple groups of through holes inside the conductive sheet, which are evenly arranged at both ends of the conductive sheet.

[0011] Preferably, the protective cover is made of XLPE (cross-linked polyethylene) and is evenly bonded to the inside of the supporting cover.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the busbar bridge for switch cabinet wiring not only realizes that during the maintenance process, the multi-directional detachable busbar bridge makes it easier for maintenance personnel to conduct detailed maintenance on its interior, thereby reducing personal safety risks, but also realizes that the busbar bridge can be used for parallel use of multiple cables, facilitating on-site installation and connection, and is relatively safe and reliable;

[0013] The bottom end of the busbar bridge body is connected to the supporting cover by bolts to achieve a fixed connection between the busbar bridge body and the supporting cover. Then, the raised strip is slid in the groove on the guide rail, and the support block and the spring limit column cooperate with each other to achieve a fixed connection between the horn cover and the busbar bridge body. The connected busbar bridge is installed on the switch cabinet. When performing maintenance, the spring limit column is pressed inward, and the horn cover is pulled out to cooperate with the support block, raised strip, guide rail and groove to achieve the separation of the horn cover and the busbar bridge body. The busbar bridge body and the supporting cover can be separated by removing the bolts, which allows for more comprehensive maintenance, reduces the difficulty of maintenance, and reduces the personal safety risk of maintenance personnel.

[0014] By passing multiple cables through multiple groups of preset through holes on the conductive sheet, the cables are prevented from getting entangled inside, which increases the difficulty of on-site installation and connection. A protective cover is wrapped around the outside of the conductive sheet. The protective cover is made of high-quality insulating material, thereby improving the safety and reliability of the busbar bridge. BRIEF DESCRIPTION OF THE DRAWINGS
