Abstract

The objective of the invention is to provide a novel circuit breaker with a cylindrical appearance. The circuit breaker is provided with a partially or wholly cylindrical appearance. Without losing functions of a traditional miniature circuit breaker, the miniature circuit breaker is advantaged by quite direct transmission, quite simple mechanisms, quite precise parts and a quite small size. The miniature circuit breaker is characterized in that the lower part is provided with a movable contact and static contact; the movable contact is provided with a stand column; the lower part of the stand column of the movable contact cooperates with the static contact; the miniature circuit breaker is also provided with an at least partially cylindrical housing body; a top opening is arranged in the top of the housing body; a starting button and a breaking button penetrate through the top opening; a groove is arranged in the inner groove of the housing body; a locking sheet is arranged in the groove and capable of rotating around a fixed rotation shaft; the top end of the movable contact is provided with a first wedge protruding outwards in the radial direction; and a locking recessed opening in which the wedge is clamped is arranged in the locking sheet.

Description

technical field [0001] The present invention relates to circuit breakers and, in particular, to a miniature circuit breaker having an at least partially cylindrical appearance. Background technique [0002] There are many kinds of circuit breakers in the prior art, but most of them are in the form of roughly cuboid boxes, and there is no circuit breaker structure with a cylindrical appearance. [0003] The present invention aims to propose a new cylindrical appearance circuit breaker, which has at least part of the cylindrical appearance, or the overall appearance is cylindrical, and it also has more direct transmission and mechanism without losing the function of the traditional miniature circuit breaker. The advantages of simpler, more streamlined components and smaller volume. It can choose the shape of its shell according to the actual installation situation of the circuit breaker and the different requirements of the environment, so as to achieve the comprehensive layo...
