Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper busbar installation technology, specifically a copper busbar installation structure for a power distribution cabinet. Background Technology
[0002] Copper busbars in a distribution cabinet are electrical conductors used to connect various electrical devices within the cabinet. They are typically made of pure copper and possess advantages such as good conductivity and low impedance, ensuring the normal operation of the electrical equipment within the cabinet. The main functions of copper busbars in distribution cabinets include conductive connection, current shunting and regulation, and reducing line impedance.
[0003] Chinese Utility Model Announcement No. CN220934630U includes a cabinet. A cabinet door is hinged to the front of the cabinet. A first slot and a second slot are respectively provided through the left and right ends of the cabinet. A copper busbar mounting assembly is detachably mounted in both the first and second slots. Two mounting holes are provided on each of the left and right inner walls of the cabinet. A combination connection assembly is fixedly mounted in the two mounting holes on the same side. A controller is fixedly connected to the rear inner wall of the cabinet. This utility model describes a copper busbar mounting structure for a distribution cabinet. By setting up the copper busbar mounting assembly, it achieves the purpose of facilitating quick installation and disassembly of copper busbars and improving operational safety; by setting up the combination connection assembly, it achieves the purpose of quickly combining different copper busbars and conveniently improving the efficiency of the distribution cabinet.
[0004] The applicant discovered some shortcomings in the use of the patent: after the copper busbar is connected to the wires and used for a certain period of time, dust or rust will appear on the surface of the copper busbar, requiring regular maintenance. If the wires on the copper busbar are removed and then the copper busbar is removed for maintenance, it is troublesome. If maintenance is carried out directly without disassembling, since the copper busbar is located deep inside the distribution cabinet and the space inside the cabinet is small, it is difficult for the staff to reach into the cabinet for construction and maintenance is not convenient.
[0005] Therefore, this utility model designs a copper busbar installation structure for a power distribution cabinet to solve the problems existing in the prior art. Utility Model Content
[0006] The purpose of this utility model is to provide a copper busbar installation structure for a power distribution cabinet to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a copper busbar installation structure for a power distribution cabinet, comprising: a cabinet body, with U-shaped plates installed on the upper sides of the inner walls of both sides of the cabinet body; sliders slidably installed inside the U-shaped plates; two sliders respectively fixedly installed on both sides of the copper busbar; a top groove is formed at the top of the sliders; a pin is slidably installed inside the top groove; the bottom of the pin and the slider are connected by a spring; and through holes are formed at both ends of the top of the U-shaped plates, which are connected to the pins. When installing the copper busbar, the slot is pressed so that the slot is located in the top groove and the spring is squeezed. Then, the slider is slid into the U-shaped plate, and the copper busbar is pushed inward until the slider slides into the deepest part of the U-shaped plate. The restoring force of the spring causes the pin to pop out through the through hole, thus limiting the slider and completing the installation of the copper busbar. This method is more convenient than bolt fixing.
[0008] Preferably, one end of the slider has a vertical groove communicating with the top groove, and a slide rod that is slidably connected to the vertical groove is installed below one end of the pin. Through the vertical groove and the slide rod, the operator only needs to press down the slide rod, which is more convenient than pressing the pin.
[0009] Preferably, a hook is installed at one end of the slide bar, which facilitates the movement of the slider.
[0010] Preferably, a slide bar is installed on one side of the slider, and a slide groove is provided on the inner wall of the U-shaped plate to slide in conjunction with the slide bar. The slide bar slides in the slide groove, which can improve the stability of the slider sliding in the U-shaped plate.
[0011] Preferably, the bottom inner wall of the U-shaped plate is provided with a long groove, and several rotating rollers are rotatably installed in the long groove. When the slider slides, the rotating rollers roll, which can reduce the friction between the slider and the U-shaped plate, making it easier for the operator to pull the slider.
[0012] Preferably, a threaded hole is provided on one side of the U-shaped plate, which facilitates fixing the U-shaped plate to the cabinet body with bolts.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. When the copper busbar needs maintenance after a certain period of use, the operator uses both hands to lower the two pins away from the through hole and squeeze the spring. Then, the operator pulls the copper busbar outward, causing the slider to slide inside the U-shaped plate. When the pin slides to the outer through hole, the restoring force of the spring causes the pin to pop up and pass through the through hole, thus limiting the copper busbar. At this time, the copper busbar is away from the deep interior of the cabinet and is located on the outermost side of the cabinet. The operator's hands do not need to be in the narrow space inside the cabinet, and there is no need to remove the wires on the copper busbar, making the maintenance of the copper busbar more convenient.
