Magnetic latching relay with good positioning conductive lead-out pins

Abstract

The invention discloses a magnetic latching relay with good positioning conductive lead-out pins. The magnetic latching relay comprises an insulating shell and a plurality of conductive lead-out pins;each conductive lead-out pin is mounted on the insulating shell, and one end of each conductive lead-out pin extends out of the insulating shell; at least one conductive lead-out pin is provided witha first positioning part and a second positioning part; a first matching part matched with the first positioning part and a second matching part matched with the second positioning part are arrangedon the insulating shell; the first positioning part is in tight fit with the first matching part; the second positioning part is in clearance fit with the second matching part; and the second positioning part is matched with the second matching part to further position the conductive lead-out pin after the first matching part is deformed to a set degree. The assembly and positioning of the conductive lead-out pins are facilitated, the positioning precision of the conductive lead-out pins can be improved, and the exertion of the performance of the magnetic latching relay is ensured.

Description

technical field [0001] The invention relates to the technical field of manufacturing magnetic latching relays, in particular to a magnetic latching relay with well-positioned conductive leads. Background technique [0002] Magnetic latching relay is a new type of relay developed in recent years. Like other electromagnetic relays, it can automatically switch on and off the circuit. [0003] The existing magnetic latching relay usually includes a plastic insulating shell, a plurality of conductive leads, a magnetic circuit system, a contact system and a pushing mechanism. A plurality of conductive leads, a magnetic circuit system, a contact system and a pushing mechanism are all mounted on a plastic insulating shell. The magnetic circuit system usually includes a yoke, a coil, and an armature assembly. The contact system includes a moving spring and a static spring. The moving spring has a moving contact, and the static spring has a static contact. Connect the push card, th...

AI Technical Summary

Problems solved by technology

Since the moving spring and the static spring are positioned by conductive pins, and the insulating shell is made of plastic, when the conductive pins extend out of the insulating shell, the part is longer and heavier, or the conductive pins extend out of the insulating shell The part of the external electrical appliance is extruded by the connecting screw to generate stress, and the matching part of the plastic insulating shell and the conductive lead-out pin is easily deformed, which will cause the deflection and displacement of the conductive lead-out pin

Once the conductive leads are deflected and shifted, the moving spring or the static spring will shift accordingly, which will cause inaccurate alignment between the moving contact and the static contact, resulting in poor contact and affecting the performance of the relay

The problem of deflection and displacement of conductive pins has not been paid enough attention in the prior art, so the prior art fails to solve the problem of good positioning of the conductive pins
