Description

Technical Field

[0001] The utility model relates to a busbar clamp and belongs to the field of power components. Background Art

[0002] Busbar clamps are common electrical connectors in power distribution systems. They are mainly used to connect busbars and play a conductive and fixed role. Busbars are high-capacity, low-impedance power transmission pipelines that can provide power to various distribution equipment and power facilities. Therefore, the reliability and stability of busbar connections are crucial to the normal operation of the power system. Busbar clamps can ensure the conductive connection between busbars, allowing current to flow smoothly and avoid power system failures. At the same time, they can also fix the position of the busbars to ensure the stability and reliability of the system.

[0003] The existing busbar clamp is installed in the switch cabinet, usually by plugging the conductive bar into the insulating seat and then installing it in the switch cabinet. An installation gap will be generated between the conductive bar and the insulating seat. For example, the Chinese utility model with publication number CN215378373U discloses a busbar clamp, including: a mounting base, a plurality of first grooves are provided on the mounting base; a plurality of insulating seats, each of the insulating seats is respectively installed in each of the first grooves, the top of the insulating seat is lower than the top of the first groove, and the insulating seat is suitable for providing a second groove, the second groove of each of the insulating seats is suitable for installing each conductive bar, and the width of the second groove is greater than the width of the conductive bar; a plurality of positioning members, each of the positioning members is respectively arranged in each of the first grooves, and the length of the positioning members is adjustable, and the two ends of the positioning members are suitable for respectively abutting against the inner side wall of the first groove and the conductive bar. The utility model does not have a waterproof function. When water enters from the outside, it is easy to cause water to enter the switch cabinet and thus fail as a whole, and the safety is poor.

[0010] Furthermore, a connecting groove is provided on the mounting plate, and the bottom of the mounting platform extends to the other side of the mounting plate through the connecting groove for connection with the switch cabinet.

[0011] Furthermore, the insulating seat is provided with a plurality of first fixing holes surrounding the mounting platform, and the mounting plate is provided with second fixing holes corresponding to the first fixing holes. The insulating seat and the mounting plate are fixedly connected by bolts through the first fixing holes and the second fixing holes.
