Description

Circuit breaker terminal clamp

technical field

The utility model relates to electrical equipment, in particular to a circuit breaker terminal clip.

Background technique

When electric power workers perform routine tests on circuit breakers, they need to connect the test line of the instrument to the terminal block of the circuit breaker mechanism box. In this process, it is necessary to disassemble and assemble the original equipment line, which may easily lead to loosening and damage of screws, affect the safe operation of the equipment, and work efficiency is not high.

Contents of the invention

The purpose of this utility model is to provide a circuit breaker that can achieve a better connection between the test line and the terminal block of the circuit breaker mechanism box, avoid disassembly and assembly of screws, thereby effectively eliminating hidden dangers in equipment operation and improving work efficiency Terminal clamp.

The purpose of this utility model is achieved in that:

A circuit breaker terminal clamp, including an insulating support made of plastic and two fixed clamps, slots are provided on both sides of the middle of the fixed clamp, and the center bolt passes through the middle of the two slots to The two fixed wire clips are hinged together, the left ends of the two fixed wire clips are toothed collets, the right ends of the two fixed wire clips are clamp handles, and the upper and lower ends of the clamping spring respectively hook the middle parts of the two fixed wire clips , press the clamp handles of the two fixed wire clips to make the chucks of the two fixed wire clips open with the center bolt as the fulcrum and be full of elasticity. The characteristics are: the insulating support is fixed on the outer wall of the slot on one side of the fixed wire clip, The left and right ends of the insulating support are processed with conductive rod holes through the left and right, the inner wall of the conductive rod hole is processed with internal threads, and the middle part of the outer wall of the conductive rod is processed with external threads. The conductive rod is connected with the insulating support through the thread. The top of the left end of the conductive rod on the head side is smooth and connected to the circuit breaker terminal. A connecting hole is processed inside the right end of the conductive rod on the clamping handle side. The connecting hole is connected to the test plug. Insulation.

The utility model is composed of two fixed clamps, an insulating support and a conductive rod. The insulating support is placed parallel to the fixed clamp. The top of the left end of the conductive rod is smooth and connected to the circuit breaker terminal. The right end of the conductive rod is connected to the test plug. . When in use, first clamp the toothed chucks at the left end of the fixed wire clamp on both sides of the terminal block, then drive the conductive rod to extend to the left end through the rotating insulating layer until the left end of the conductive rod is in close contact with the circuit breaker terminal, and finally put the test wire Connected to the connection hole, the test line can be directly connected to the circuit breaker terminal through the conductive rod without disassembling the circuit breaker terminal line.

Therefore, the utility model has the advantages of better connection between the test line and the terminal block of the circuit breaker mechanism box, avoiding disassembly and assembly of screws, thereby effectively eliminating hidden dangers in equipment operation, improving work efficiency, simple structure, practicality, The advantage of good effect.
