Problems solved by technology

The disadvantage is that the thermosetting material is easy to wear and tear, and it cannot be installed repeatedly during equipment inspection. Multiple assembly is easy to damage the screw holes, resulting in installation failure and affecting the use of the product.
[0003] There are a large number of output or control wiring harnesses in the transformers and releases of electronic products, which usually lack standardized wiring during layout, resulting in messy wiring harnesses connected to the controller, and easy to damage the wires during installation, resulting in functional damage or other problems

Abstract

The tripper fixing device comprises a tripper base and a cover, a tripper body is installed on the tripper base, the tripper fixing device is characterized by further comprising a support, the support is installed on the cover, the front portion of the tripper base is fixed to the support, and the rear end of the tripper base is fixed to the cover through a buckle. Under the condition that the space size is not increased, the support is additionally arranged to be matched with the tripper base for installation, the fixing reliability of the tripper is guaranteed, the rejection rate of cover parts is reduced, the support further has the wiring function, a wiring groove does not need to be additionally arranged independently, and the number of parts is reduced.

Description

technical field [0001] The invention belongs to the technical field of molded case circuit breakers, and in particular relates to a tripper fixing device for circuit breakers. Background technique [0002] The base part of the existing molded case circuit breaker is made of thermosetting material, and screws are usually used to install or fix other structures on the base. It is divided into two types, preset insert nuts and use combination screws to fix, this method is relatively reliable, and the installation effect will not be affected by repeated disassembly. The disadvantage is that the manufacturing cost is increased, and at the same time, it is limited by space, which has certain requirements on the thickness of the casing, and the nut cannot be arranged in this situation. The second method is to reserve screw holes on the base, and use self-tapping screws to fix the required components, which has the advantages of simple structure and low manufacturing and production...
