Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment cabinets, and in particular to an insulated cable connector for an electrical equipment cabinet. Background Art

[0002] Electrical equipment cabinet is a general term for motor control center. Electrical equipment cabinet is made of steel to protect the normal operation of components. The materials used to make electrical equipment cabinet are generally divided into hot-rolled steel plate and cold-rolled steel plate. Cold-rolled steel plate is softer than hot-rolled steel plate and more suitable for the production of electrical equipment cabinet. Electrical equipment cabinet has a wide range of uses and is mainly used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. Cable is a very important electrical connection equipment. After the cable is crimped with copper joints, it is connected to the copper busbar of the circuit breaker in the electrical equipment cabinet.

[0003] The insulated cable connectors of existing electrical equipment cabinets have certain defects when in use. The copper joints and fastening bolts of the cable connections and other live parts are exposed, which increases the failure rate of the electrical system and endangers personal safety. Therefore, improvements are now made to the insulated cable connectors of electrical equipment cabinets. Utility Model Content

[0004] In view of the deficiencies of the prior art, the present application provides an insulated cable connector for an electrical equipment cabinet, which overcomes the deficiencies of the prior art and aims to solve the problem of exposed live parts such as copper joints and fastening bolts of cable connections.

[0006] By adopting the above technical solution, the insulating sliding sleeve is set to slide on the outer surface of the insulating protective sleeve to cover and protect the connection between the cable copper joint of the cable and the outlet copper busbar connector of the circuit breaker, forming an insulating space to prevent any live parts from being exposed, reduce the failure rate of the electrical system, and protect personal safety.

[0007] As a preferred technical solution of the present application, the limiting unit includes a spring, one end of which is fixedly connected to the inner wall of the slot, the other end of which is fixedly connected to a sliding block, and a clamping block is fixedly installed at the lower end of the sliding block.

[0008] By adopting the above technical solution, the position of the sliding block is adjusted by utilizing the elastic force of the spring, so that the clamping block fixedly installed at the lower end of the sliding block fits on the insulating protective sleeve, ensuring that the insulating sliding sleeve is firmly sleeved on the outer surface of the insulating protective sleeve.

[0009] As a preferred technical solution of the present application, a guide block is fixedly connected to one side of the sliding block, the guide block is in an L-shaped structure, and one end of the guide block slides through the insulating sliding sleeve and extends to the outside.

[0010] By adopting the above technical solution, the guide block is pulled to drive the sliding block to slide upward, thereby driving the clamping block to separate from the outer surface of the insulating protective sleeve, ensuring that the insulating sliding sleeve can slide up and down on the outer surface of the insulating protective sleeve, and covering and protecting the connection between the cable copper joint and the outlet copper busbar connector, forming an insulating space to prevent the live body from being exposed.

[0011] As a preferred technical solution of the present application, sliding grooves are provided on both sides of the outer surface of the insulating protective sleeve, and the clamping block is slidably connected inside the sliding grooves.

[0012] By adopting the above technical solution, the sliding groove provides a stable sliding track for the sliding of the insulating sliding sleeve.

[0013] As a preferred technical solution of the present application, a fixing plate is fixedly installed at the bottom of the insulating protective sleeve, and fixing holes are opened on the outer surface of the fixing plate. The number of the fixing holes is four and they are distributed in a linear array on the outer surface of the fixing plate.

[0014] By adopting the above technical solution, it is ensured that the insulated cable connector can be fixedly installed inside the electrical equipment cabinet to prevent the cable from slipping and shifting.

[0015] As a preferred technical solution of the present application, the outer surfaces of the cable copper joint and the outlet copper busbar connector are both provided with through holes, and the through holes are plugged with cable connecting bolts to fix the cable copper joint and the outlet copper busbar connector together.

[0016] By adopting the above technical solution, the cable copper joint and the outlet copper bus connector are tightly connected together by using cable connecting bolts, thereby preventing poor contact caused by unstable connection from affecting conductivity.

[0017] Beneficial effects of this application:

[0018] In the utility model, the insulating sliding sleeve is controlled by the set limit unit to slide up and down along the sliding groove on the outer surface of the insulating protective sleeve, so as to cover and protect the connection between the cable copper joint of the cable and the outlet copper bus connector of the circuit breaker, thereby forming an insulating space, preventing any live body from being exposed to the outside, reducing the failure rate of the electrical system, and protecting personal safety. The set fixing plate can be used to fix the insulating cable connector inside the electrical equipment cabinet to prevent the cable from sliding and shifting.
