Problems solved by technology

[0004] Although the above-mentioned scheme has many advantages above, there are the following technical problems in the above-mentioned scheme: the contact mode between the moving spring assembly and the push block is a surface-to-surface contact, and the surface-to-surface contact is due to the large contact area. , causing the rebound of the moving spring assembly to be affected, that is, the elastic rebound ability is poor;
[0005] Secondly, the existing magnetic latching relay still has the detection function of detecting whether the contact has been made after the moving contact and the static contact have been contacted, which is unsafe to use

Embodiment Construction

[0062] The following are specific embodiments of the invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0063] Such as Figure 1-3 As shown, the double-contact magnetic latching relay includes a housing 1. Specifically, the housing 1 includes a bottom case 11 and a cover 12 covering the bottom case 11. The bottom case 11 and the cover 12 are connected by a buckle structure.

[0064] Further, the buckle structure includes several buckles 17 arranged on the outer wall of the open end of the bottom case 11 , and there are buckle ears 18 in the circumferential direction of the cover 12 that cooperate with the said buckles 17 one by one.

[0065] The protruding buckle 17 and buckle ear 18 provided are convenient for assembly and disassembly.

[0066] In the bottom case 11, a partition plate 13 capable of dividing the interior of the bot...

Abstract

The invention belongs to the technical field of relays, especially relates to a double contact magnetic latching relay, and solves the technical problem of poor rebound performance of the prior art. The double contact magnetic latching relay comprises a shell; the shell is internally provided with a coil assembly and an armature assembly; the armature assembly is connected with a push block, which can force the armature assembly to move when the coil assembly is powered on so that the push block moves relative to the shell; and the shell is also internally provided with a double contact stable sheet component and a double contact movable sheet component, and the movement of the push block can drive the double contact movable sheet component to be close to the double contact stable sheet component or away from the double contact stable sheet component. The double contact magnetic latching relay provided by the invention has the advantage that the rebound performance can be improved.

Description

technical field [0001] The invention belongs to the technical field of relays, in particular to a double-contact magnetic latching relay. Background technique [0002] The magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it can automatically switch on and off the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the effect of the permanent magnet, and the switching state of the relay is triggered by a pulse electric signal of a certain width. [0003] The current magnetic latching relay has a movable contact on its moving reed, and a movable contact cannot pass a large current, which reduces the application range of the magnetic latching relay. How to solve this technical problem, for example, the Chinese patent literature discloses a push rod structure of a large current normally closed magnetic ...
