contactor

Abstract

The contactor includes a body and a contact support. The contact support is movably installed in the installation cavity of the body. The body of the contact support is provided with a plurality of lower accommodation chambers for accommodating the moving contacts. The plurality of lower accommodation chambers are mutually connected. It is arranged at intervals, and the side wall of the body is provided with a plurality of position-limiting structures located between two adjacent lower accommodation chambers, and the plurality of position-limiting structures cooperate with a plurality of inserting plates in the installation cavity; the inserting plates include connecting The connecting end and the bent root of the plug-in plate are connected to the side walls of the installation cavity, and each limiting structure includes a first limiting plate and a The second limiting plate, the first limiting plate includes a connected connecting root and a bent end, the connecting root is connected to the body and is spaced from the second limiting plate to form a plug that matches the connecting end of the plug board. The groove is arranged opposite to the bent root of the inserting plate at the bent end. The invention provides a contactor with simple structure and good arc insulation effect.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a contactor. Background technique [0002] The contact support of the contactor is movably installed in the body. Usually at least one accommodation cavity is formed on the contact support. The moving contact is installed in the accommodation cavity. One end of the spring is installed on the moving contact and the other end is installed in the container the top of the cavity. The static contact is fixedly installed on the body, opposite to the moving contact. When the contactor is working, the moving contact moves up and down and the static contact opens or closes, so that the working circuit is connected or disconnected. [0003] The contact support moves under the attraction of the energized coil, so that the moving contact and the static contact are opened or closed, and an arc is generated at the moment of opening or closing. There is an isolation insulator...
