Problems solved by technology

[0004] However, the relays in the prior art have a simple structure, and the position of the moving contact assembly is maintained by the magnetic force of the electromagnet after the moving contact assembly contacts the static contact assembly, or the spring force maintains the position.
This method results in poor contact performance between the moving contact assembly and the static contact assembly of the relay, and it is easy to cause malfunction when the relay is subjected to vibration
[0005] For this reason, in the prior art, there is a scheme of using a mechanical structure to keep the moving contact assembly in contact with the static contact assembly, but due to the addition of the mechanical structure, the response speed of the relay is slow, which affects the performance of the relay.

Embodiment 1

[0034] Such as figure 1 , figure 2 , a dual magnetic relay, comprising a moving contact assembly 1 and a static contact assembly 2 cooperating with the moving contact assembly 1, there are two static contact assemblies 2, and the moving contact assembly 1 consists of the first An electromagnet 3 drives it to contact with the static contact assembly 2. The double magnetic relay also includes a holder for positioning the position of the movable contact assembly 1. The holder includes a positioning rod 4 and drives the positioning rod 4 to reciprocate in a linear direction The moving second electromagnet 5, after the movable contact assembly 1 contacts one of the static contact assemblies 2, the positioning rod 4 contacts the movable contact assembly 1 to position the movable contact assembly 1, During the action of the movable contact assembly 1 , the positioning rod 4 leaves the movable contact assembly 1 to prevent the positioning rod 4 from interfering with the movable cont...

Embodiment 2

[0038] Such as figure 1 , figure 2 , the first electromagnet 3 includes a reciprocating telescopic part 6 , the moving direction of the telescopic part 6 is perpendicular to the moving direction of the positioning rod 4 .

[0039] That is to say, when the telescopic part 6 moves vertically, the positioning rod 4 moves horizontally. This solution simplifies the structure of the dual magnetic relay and reduces the manufacturing cost of the dual magnetic relay.

Embodiment 3

[0041] Such as figure 1 , figure 2 , The positioning rod 4 is provided with a notch for making the positioning rod 4 and the movable contact assembly 1 surface-contact, and there are two notches.

[0042] The notch is the plane arranged on the positioning rod 4 , which is made by removing material, and the plane can also be formed by the shape of the positioning rod 4 .

[0043] The setting of the gap optimizes the positioning accuracy of the positioning rod 4 and prolongs the service life of the positioning rod 4 .

Abstract

The invention relates to power distribution devices, in particular to a dual magnetic relay, which belongs to the field of relays. The invention provides a double magnetic relay, which is used to make the contacts of the relay have good contact performance and fast response speed. In the dual magnetic relay provided by the present invention, the setting of the retainer can effectively locate the moving contact assembly, greatly improving the contact performance between the moving contact assembly and the static contact assembly, thereby effectively improving the performance of the relay. This makes the relay more stable during the working process, avoids the reduction of the contact performance of the contact due to vibration, and improves the stability of the relay during the working process.

Description

technical field [0001] The invention relates to power distribution devices, in particular to a dual magnetic relay, which belongs to the field of relays. Background technique [0002] Relays are mainly used to break circuits and are widely used in the prior art. [0003] The relay in the prior art uses an electromagnet to drive the movable contact assembly of the relay to move, and the electromagnet has the advantages of fast response speed and the like, and is widely used. [0004] However, the relay in the prior art has a simple structure, and the position of the movable contact assembly is maintained by the magnetic force of the electromagnet or the force of the spring to maintain the position after the movable contact assembly contacts the static contact assembly. This method results in poor contact performance between the moving contact assembly and the static contact assembly of the relay, and it is easy to cause malfunction when the relay is subjected to vibration. ...
