Problems solved by technology
[0002] The relay is a commonly used basic component as an automatic switch in the circuit. There are many types of relays. Electromagnetic relays are one of the commonly used ones. Electromagnetic relays need to be equipped with contact units. In addition, during the assembly process of the relay, there will inevitably be product dust, which will often interfere with the poor conduction of the contact unit, resulting in unstable performance of the electromagnetic relay

The invention relates to the technical field of relays, and particularly discloses a contact structure of an electromagnetic relay. The structure comprises an insulating body, a moving terminal and astatic terminal which are arranged on the insulating body; the insulating body comprises a first body and a second body detachably connected with the first body. The first body is provided with a receding groove, and the receding groove penetrates through the top face of the first body; the movable terminal and the static terminal each comprise a welding foot and a contact; the welding feet extendout of the first body to be welded to an external circuit board, the contact is located in the receding groove, and the second body is used for covering an opening of the receding groove. A through hole is formed in the side wall of the first body, communicates with the receding groove and penetrates through the side wall of the first body. The first body and the second body are matched to coverand protect the static terminal and the moving terminal, so the static terminal and the moving terminal are prevented from being damaged due to exposure; contacting point centrality of the terminals is checked through the through holes, blowing dust removal is carried out through the through holes, and stability of conduction performance of the terminals is ensured.
Description
technical field [0001] The invention relates to the technical field of relays, and in particular discloses a contact structure of an electromagnetic relay. Background technique [0002] The relay is a commonly used basic component as an automatic switch in the circuit. There are many types of relays, and the electromagnetic relay is a commonly used one. The electromagnetic relay needs to be equipped with a contact unit. The contact unit of the existing electromagnetic relay is in a bare state and is vulnerable to damage. In addition, during the assembly process of the relay, there will inevitably be product dust, which will often interfere with the poor conduction of the contact unit, resulting in unstable performance of the electromagnetic relay. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a contact structure of an electromagnetic relay, which uses the coopera...
