Problems solved by technology

The generation of pollution particles further intensifies the friction between the two, which hinders the movement performance of the moving contact and long-term friction will cause the silver point misalignment (gap) between the moving contact and the static contact

Abstract

The invention discloses a modularized breaking unit with a bracket guide assembly, wherein the modular breaking unit comprises a unit housing; a moving contact bracket of the modular breaking unit is accommodated in the unit shell; a moving contact of the modularized breaking unit is mounted on the moving contact bracket; the bracket guide assembly is arranged in the unit shell and is used for guiding the moving contact bracket to move between an opening position and a closing position; the bracket guide assembly is made of a thermoplastic plastic material; and the moving contact bracket is made of a thermosetting plastic material. The contactor comprises at least one modularized breaking unit.

Description

technical field [0001] The present disclosure relates to a modular breaking unit having a bracket guide assembly. The present disclosure also relates to a contactor comprising at least one of said modular breaking units. Background technique [0002] In the prior art, both the housing of the breaking unit and the movable contact bracket accommodated therein are made of thermosetting materials. There is friction between them due to relative motion, which in turn produces pollution particles. The generation of contamination particles further exacerbates the friction between the two, which hinders the moving performance of the moving contact and long-term friction can lead to misalignment (gap) of silver points between the moving and stationary contacts. In order to obtain good friction between them, good shape and material guidance must be created between them. SUMMARY OF THE INVENTION [0003] To address one or more deficiencies in the prior art, a modular breaking unit ...
