Abstract

The invention provides a cage-shaped fastening pressing plate type Wiring device used for a molded case circuit breaker. The wiring device comprises a wiring frame which can be fixed in a mounting base on the two corresponding side edges of the molded case circuit breaker and is formed by an upper edge, a lower edge, a left edge and a right edge in an encircling manner; a screw hole is formed in the upper edge of the wiring frame; a stud capable of rotating up and down is configured in the screw hole; a tile-shaped gasket is connected with the lower end part of the stud; a static contact internally connected with a breaker is configured on the lower edge of the wiring frame; a polygon sunken hole is formed in the upper end part of the stud; a narrow groove is formed in the lower edge of the wiring frame and parts of the wiring frame on the two sides of the narrow groove are spliced together by a 'bone-shaped' nonmagnetic material. The wiring device has the characteristics of being simple in structure, high in reliability, good in wiring fastness, uneasy in wire off, convenient in use and the like.

Description

technical field [0001] The invention relates to a cage-type fastening plate wiring device for a molded case circuit breaker, belonging to the technical field of power distribution equipment. Background technique [0002] A molded case circuit breaker is a circuit breaker that has a housing made of molded insulating material as an integral part of the circuit breaker. The plug-in circuit breaker is based on the molded case circuit breaker, and the plug-in wiring device specially matched with it is used for the connection and isolation of the circuit in the power distribution and control equipment. The plug-in circuit breaker is divided into front panel and rear panel . The features of the plug-in type circuit breaker are as follows: on the mounting plate of the complete set of devices, a circuit breaker mounting base is installed first, there are 6 plugs on the mounting base, and 6 sockets (power supply terminal, load terminal, etc.) 3 at each end); there are bolts behind t...
