Abstract

The present invention aims to propose a new cylindrical appearance circuit breaker, which has at least a partial cylindrical appearance, or the overall appearance is cylindrical. It also has more direct transmission and mechanism without losing the function of the traditional micro circuit breaker. It has the advantages of simpler, more streamlined components and smaller size. A miniature circuit breaker, which is characterized in that it includes: a movable contact with a column at its lower part and a static contact. The lower end of the column of the movable contact matches the static contact and has an at least partially cylindrical shell. A top opening is provided on the top of the casing. The start button and the disconnect button pass through the top opening. A groove is provided on the inner wall of the casing. A locking piece is provided in the groove. The locking piece can rotate around a fixed rotating shaft. The top of the contact has a first wedge protruding radially outward, and the locking piece is provided with a locking notch that is locked with the wedge.

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...
