Detailed Description

The present invention will be further described with reference to the following specific embodiments, but the present invention is not limited to these specific embodiments. It will be recognized by those skilled in the art that the present invention encompasses all alternatives, modifications, and equivalents as may be included within the scope of the claims.

Example one

As shown in fig. 1, a circuit breaker convenient to install is shown, including casing 1 that has accommodating space, the circuit breaker subassembly of installing in casing 1 and assemble in the handle 2 of casing 1 front end, the circuit breaker subassembly includes two binding post 3, and the upper and lower both ends face of casing 1 is provided with the wiring mouth respectively, and the outside wire passes through the wiring mouth to be connected with binding post 3, is provided with wire guide 4 outside the wiring mouth, and wire guide 4 and casing 1 fixed connection. In this embodiment, two wiring ports are symmetrically arranged on the upper and lower sides of the housing 1, that is, the central axes of the two wiring ports are the same straight line. The wiring mouth is just to binding post 3 setting, and external conductor passes the wiring mouth and is connected with binding post 3.

In this embodiment, the wire guide 4 is specifically configured to be a frustum shape with two open ends, and the open area of one end far away from the housing 1 is larger than the open area of one end fixedly connected to the housing 1.

As shown in fig. 2 and 4, the end of the wire guide 4 away from the housing 1 is further disposed obliquely with respect to the upper end surface of the housing 1, i.e., the distance D1 from the side close to the front end surface of the housing 1 to the housing 1 is smaller than the distance D2 from the side away from the front end surface of the housing 1 to the housing 1.

Further, in the present embodiment, the housing 1 includes a left housing 5 and a right housing 6. The left shell 5 and the right shell 6 are fixed through screws. The wire guide 4 includes a left wire guide 7 and a right wire guide 8, wherein the left wire guide 7 is fixed to the upper end surface of the left housing 5, and the right wire guide 8 is fixed to the upper end surface of the right housing 6. When the left and right housings 5 and 6 are fixedly coupled together by screws, the left and right wire guides 7 and 8 form the integrated wire guide 4.

In order to prevent the wire guide 4 from being separated from the housing 1 during long-term trial use, the left housing 5 and the left wire guide 7 are integrally formed, and the right housing 6 and the right wire guide 8 are integrally formed, so that the housing 1 is ensured to have better integrity and strength, and meanwhile, the production efficiency and the assembly efficiency are also improved.

Further, the lead guide 4 is made of a carbonate material, and the material has good electrical insulation, dimensional stability and chemical resistance, and also has the characteristics of self-extinguishing, flame retardance, no toxicity and the like, and is safe and reliable to use.
