Problems solved by technology

[0003] In the existing example, the structure of the circuit breaker is: there are connecting rods, working plates and cross bars between the handle and the movable contact, and the movable contacts are driven by the working plate and the cross bar. Therefore, there are Due to the large number of parts and complex structure, the work of assembling parts to the body is cumbersome.

Embodiment Construction

[0034] Below, refer to Figure 1 to Figure 11 An embodiment of the present invention will be described.

[0035] The circuit breaker of the present embodiment includes: in the body 1 formed by connecting the first side case 1A and the second side case 1B made of synthetic resin on both sides, two side by side in the width direction of the body 1 Fixed contacts 2A, 2B; two movable contacts 4A, 4B of movable contacts 3A, 3B that are opposite to each fixed contact 2A, 2B and can be freely contacted and separated; drive these two movable contacts 4A, 4B of the opening and closing mechanism 5; and, according to the closing and opening operation of the handle 6, each movable contact 3A, 3B is connected (contacted, separated) with each fixed contact 2A, 2B through the opening and closing mechanism 5; In the height direction of the body 1, each fixed contact 2A, 2B and each movable contact 4A, 4B are arranged up and down, and among the two movable contacts 4A, 4B, there are two fixed...

Abstract

A circuit breaker, the opening and closing mechanism 5 for driving the movable contacts 4A and 4B includes: a handle 6; a connecting member 43 for connecting the handle 6 to the movable contact 4A on the side of the voltage pole; The stop member 58 of the convex stop portion 60 of the rear end portion of 4A; the drive member 40. Only the connection member 43 exists between the handle 6 and the movable contact 4A, and the stopper member 58 directly locks the movable contact 4A. Therefore, compared with the past, the number of parts can be reduced, the structure can be simplified, and the The parts assembly work on the body 1 becomes easy to carry out.

Description

technical field [0001] The invention relates to a circuit breaker. Background technique [0002] A conventional circuit breaker is disclosed in JP-A-2001-15007. In the conventional circuit breaker described in the publication, the operating plate is connected to the handle through a connecting rod. When the handle is turned with one end side of the operating plate stopped by the stop member, the other end of the operating plate will The cross bar pressed by the side rotates, and the movable contact supported together with the compression spring that provides contact pressure to the cross bar rotates together with the cross bar to close the contact part. [0003] In the existing example, the structure of the circuit breaker is: there are connecting rods, working plates and cross bars between the handle and the movable contact, and the movable contacts are driven by the working plate and the cross bar. Therefore, there are Due to the large number of parts and complex structu...
