Abstract

The invention discloses an electric contact device for a universal circuit breaker. The electric contact device comprises a movable wiring assembly arranged on the side wall of a circuit breaker body and a static wiring assembly arranged on the side wall of a base, wherein the movable wiring assembly comprises a plurality of male end plugging bodies and two movable contact pieces which are respectively arranged on the upper side and the lower side of each male end plugging body in an extending manner; and the static wiring assembly comprises a plurality of female end connecting bodies and two static contact pieces which are arranged in inner cavities of the female end connecting bodies respectively, and the two static contact pieces protrude and extend oppositely at the opening ends of the female end connecting bodies to form elastic clamping opening structures. When the circuit breaker body moves into the base, the male end plugging bodies penetrates into the open end and are plugged between the elastic clamping opening structures, so that the two static contact pieces and the two movable contact pieces are respectively kept in close contact, the contact pressure is improved, the contact stability between the male end plugging bodies and the female end connecting bodies is ensured, the phenomena of loosening and shaking are prevented, the electric contact device is convenient to install and use, and wiring operation is more convenient.

Description

technical field

[0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to an electrical contact device for a universal circuit breaker. Background technique

[0002] The universal circuit breaker generally consists of two parts, which are divided into a fixed drawer seat and a circuit breaker body. The line on the drawer base is connected to the main circuit, and the line on the circuit breaker body is connected to the external circuit. In order to connect the main circuit and the external circuit, it is usually necessary to install a secondary circuit contact group on the universal circuit breaker. The secondary circuit contact group is an electrical contact device in the control circuit of the universal circuit breaker, which is directly for the user to wire to control the circuit breaker. Used by internal components, the secondary circuit contact group includes moving terminals and static terminals. The moving terminals ar...
