Description

Technical Field

[0001] The utility model relates to the technical field of busbar clamps, in particular to a busbar clamp. Background Art

[0002] The busbar clamp is a device used to connect the power busbar, and is often used in fixed switchgear and other power equipment. The busbar clamp has good mechanical strength to ensure safe and reliable clamping of the power busbar, and can withstand the pressure under normal operation and abnormal conditions. It plays an important role in connecting and transmitting current in the power system, ensuring the normal operation and safety of the power system.

[0003] In the existing patent literature, there is a patent with a publication number of CN 212258093 U and a patent name of "A switch cabinet busbar clamp". This patent provides an upper insulating busbar clamp, which is pushed downward under the elastic action of a spring to clamp and fix the busbar; however, the upper insulating busbar clamp lacks a structure to position it. When the busbar is actually installed or disassembled, the staff needs to use at least one hand to push the upper insulating busbar clamp upward all the time to ensure the smooth installation or disassembly of the busbar. Then, when the staff installs or disassembles the busbar, they only have the other hand to operate, which causes inconvenience in the installation or disassembly of the busbar. Utility Model Content

[0004] The utility model provides a busbar clamp to solve the problems existing in the prior art.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A busbar clamp comprises a main installation frame, wherein a plurality of insulating wire clamping seats are slidably connected inside the main installation frame, an insulating pressing block is slidably installed in the inner cavity of the insulating wire clamping seat, and springs are installed on both sides of the insulating pressing block to push it downward all the time; a plug penetrating the insulating pressing block is slidably connected above the insulating pressing block, and a limit plate is fixed on the pin body of the plug to prevent the plug from being detached, and a plug hole is also provided above the inner cavity of the insulating wire clamping seat, and when the insulating pressing block is compressed by a spring and pushed to the uppermost part of the inner cavity of the insulating wire clamping seat, the plug and the plug hole cooperate to position the insulating pressing block.

[0007] By adopting this solution, by setting the pins and the sockets, the insulating wire clamp seat can be pushed to the top when the switch cabinet busbar is installed or removed. At this time, the insulating pressing block can be fixed by the cooperation of the pins and the sockets. Therefore, when installing or removing the switch cabinet busbar, there is no need to use one hand to push the insulating pressing block all the time, which is both labor-saving and convenient during operation.

[0008] As a preferred embodiment of the busbar clamp, damping is provided on the sliding contact surface between the latch and the insulating pressing block.

[0009] By adopting this solution, damping can be provided to reduce the smoothness of the latch when it is pulled out and slid, thereby improving the reliability of the latch and the socket after assembly.

[0010] As a preferred implementation of the busbar clamp, a second spring is also mounted on the latch pin, and the second spring pushes the latch pin to always slide toward the location of the insertion hole.

[0011] By adopting this solution, in order to further improve the reliability of the assembled pin and the socket, a second spring is provided so that the second spring pushes the pin to always be assembled with the socket, so that the pin is not easily separated from the socket, and is more stable and reliable during use.

[0013] By adopting this solution, by setting a guide shaft, it will be more stable when pushing the insulating pressing block to slide vertically up and down.

[0014] As a preferred embodiment of the busbar clamp, a lower positioning groove is provided on the bottom surface of the inner cavity of the insulating clamp seat, and an upper positioning groove is also provided on the bottom of the insulating lower pressure block. The lower positioning groove and the upper positioning groove are arranged opposite to each other and are located on the same vertical line. The switch cabinet busbar is clamped and fixed between the lower positioning groove and the upper positioning groove.

[0015] With this solution, by providing a lower positioning groove and an upper positioning groove, the upper and lower ends of the switch cabinet busbar can be limited when clamping it.

[0016] As a preferred embodiment of the busbar clamp, avoidance grooves located on the insulating clamping seat are also opened on both sides of the lower positioning groove, and fastening top screws penetrating into the lower positioning groove are installed in the avoidance groove.

[0017] This solution is adopted to further improve the stability of the busbar when clamping. By setting a tightening screw, the two sides of the switch cabinet busbar can be tightened and fixed, thereby ensuring an enhanced fixing effect of the switch cabinet busbar.
