Embodiment

[0049] This example will specifically explain the relay provided by the present invention, such as figure 1 , figure 2 As shown, it includes an insulating cover 1, two static contact bridges 3, a moving contact bridge 2, a drive shaft 4 and a drive mechanism;

[0050] The two static contact bridges 3 are fixedly installed on the insulating cover 1;

[0051] The upper end of the driving shaft 4 extends into the insulating cover 1, and the moving contact bridge 2 is installed on the upper end of the driving shaft 4 through insulating parts;

[0052] The driving mechanism is installed on the lower end of the drive shaft 4, and is used to drive the drive shaft 4 to drive the moving bridge 2 to move, so that the two static bridges 3 are attracted to the moving bridge 2 or disconnect;

[0053] Both the movable contact bridge 2 and the static contact bridge 3 are known to the public. The movable contact bridge 2 is a sheet metal with a hole in the center, and its contact with the...

Abstract

In order to overcome problems that a contact of a current relay is not conducted in a conducting process or the contact of the current relay is still connected when supposing to disconnect and then a relay failure is caused and safety incidents happen. The invention provides a relay. The relay comprises an insulation housing, two static contact bridges, a moving contact bridge, a driving shaft and a driving mechanism and also comprises an auxiliary detection structure; the auxiliary detection structure comprises a first auxiliary terminal and a second auxiliary terminal; the first auxiliary terminal comprises a lead-out terminal and an elastic contact terminal which are electrically connected to each other. The relay can fast detect faults through the auxiliary detection circuit.

Description

technical field [0001] The invention relates to the field of relays. Background technique [0002] Existing relays generally include an insulating cover, two static contact bridges, a moving contact bridge, a drive shaft and a drive mechanism; the two static contact bridges are fixedly mounted on the insulating cover; the upper end of the drive shaft extends into the In the insulating cover, the moving contact bridge is fixedly installed on the upper end of the driving shaft through an insulating part; the driving mechanism is installed on the lower end of the driving shaft, and is used to drive the driving shaft to drive the moving contact bridge to The two static contact bridges are attracted to or disconnected from the movable contact bridge. The points where the above-mentioned static touch bridge and the moving touch bridge contact are called contacts, the contacts on the static touch bridge are called static contacts, and the points on the moving touch bridge are call...
