Handle of breaker

Abstract

The invention relates to a breaker, in particular to a handle of a breaker. The handle of the breaker w comprises a handle body (1) and a lever assembling groove (2) which is formed in the middle of the lower end face of the breaker. The handle of the breaker is characterized in that the lever assembling groove (2) comprises a left limit side wall and a right limit side wall, a left clamping protruding block (4) is arranged on the left limit side wall, a right clamping protruding block (5) is arranged on the right limit side wall, when a lever (3) is arranged in the lever assembling groove (2) in a plug-in mounting mode, a left limit side wall body and a right limit side wall body are respectively connected with the left clamping protruding block (4) and the right clamping protruding block (5) in a clamping mode, and the handle body (1) is connected with the lever (3) in a clamping mode. The handle of the breaker is simple in structure and low in cost. Due to the fact that the handle body is tightly connected with the lever in a clamping mode, assembling is simple and quick, and the breaking speed of the breaker is improved.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to an operating part of the circuit breaker, in particular to a handle of the circuit breaker. Background technique [0002] The operating part of the existing circuit breaker is an exposed handle, and the closing and opening operations are realized by pushing the handle back and forth, such as figure 1 As shown, the handle includes a handle main body 1, the end face of which is located in the circuit breaker is provided with a lever assembly groove 2, the handle main body 1 and the lever 3 are connected by a live fit, and the handle only relies on the upper cover of the circuit breaker to achieve alignment. Its limit, such a connection method has the following defects: [0003] 1. During the assembly process of the circuit breaker, due to the loose connection between the handle body and the lever, it is easy to fall off, which affects the assembly speed and production efficiency; [0004] 2. ...

AI Technical Summary

Problems solved by technology

[0003] 1. During the assembly process of the circuit breaker, due to the loose connection between the handle body and the lever, it is easy to fall off, which affects the assembly speed and production efficiency;

[0004] 2. During the debugging process, because the handle body and the lever are not tightly connected, it is easy for the operator to touch the weak current and make the operator feel uncomfortable;

[0005] 3. During the use of the circuit breaker, due to the loose connection between the handle body and the lever, it is easy to rub against the upper cover of the circuit breaker during the closing and opening process, which affects the working performance and breaking speed
