relay

Abstract

The invention discloses a relay. The relay comprises a housing, a static contact bridge, a moving contact bridge, a push mechanism and a detection assembly; the static contact bridge is arranged on the housing; the moving contact bridge is between a conducting position where the moving contact bridge is conducted with the static contact bridge and a disconnection position where the moving contact bridge is disconnected from the static contact bridge and the moving contact bridge is movably arranged inside the housing; the push mechanism is connected to the moving contact bridge for pushing the moving contact bridge to move between the conducting position and the disconnection position; the detection assembly comprises an auxiliary moving contact bridge and an auxiliary static contact bridge; the auxiliary moving contact bridge is connected to the push mechanism; the auxiliary static contact bridge is arranged on the housing; when the moving contact bridge is in the conducting position, the auxiliary moving contact bridge is conducted with the auxiliary static contact bridge; when the moving contact bridge is in the disconnection position, the auxiliary moving contact bridge is disconnected from the auxiliary static contact bridge; and a blocking wall is arranged between the static contact bridge and the auxiliary static contact bridge. According to the relay of the invention, the detection assembly can quickly detect a non-conducting condition or a connection failure between the moving contact bridge and the static contact bridge on a circuit where the relay is positioned and can provide feedbacks timely, which can improve working reliability and safety of the relay.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a relay. Background technique [0002] In the relay of the related art, after the contact of the relay is closed, there is no corresponding detection component to judge whether the detection contact is conductive. Once the contact is not conductive or the contact is bonded, it is difficult to quickly detect when the relay is in use. And give feedback on problem points. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a relay, which can detect whether the contacts are conducting or not, and has high reliability. [0004] The relay according to the embodiment of the present invention includes: a casing; a static contact bridge, the static contact bridge is arranged on the casing; a moving contact bridge, the moving contact ...
