A lead-out, plug-in electromagnetic relay and its assembly method

Abstract

The invention discloses an outgoing pin, a pluggable electromagnetic relay and an assembly method of the pluggable electromagnetic relay. The pluggable electromagnetic relay comprises outgoing pins and a base; the base is provided with jacks; each outgoing pin is provided with an upper step and a lower step; one end of each outgoing pin and the upper step thereof penetrate the corresponding jack of the base so that the upper step of the outgoing pin is correspondingly arranged at the edge of the upper end of the jack. The upper edge of each outgoing pin, along the thickness-wise middle of the outgoing pin, is cut with a cutter so as to form a cut along the width-wise direction of the outgoing pin, the upper step of the outgoing pin is provided with protrusions protruding two outer sides of the upper step in the thickness-wise direction, and the protrusions lock the edge of the upper end of the corresponding jack. By the use of the outgoing pin, the pluggable electromagnetic relay and the assembly method of the pluggable electromagnetic relay, the problems that the outgoing pins and the base fitting in the thickness-wise direction loosen easily, the requirement on fitting size tolerance of the base and the outgoing pins is high and machining cost of parts is high are solved; meanwhile, the problem that spot welding positions of the coil outgoing pins are large in size so that materials are wasted is solved.

Description

technical field [0001] The invention relates to an electromagnetic relay, in particular to a lead-out, plug-in electromagnetic relay and an assembly method thereof. Background technique [0002] Electromagnetic relay is an automatic control device whose output will change in leaps and bounds when the input reaches a certain value. Electromagnetic relays are widely used in automation systems, electronic equipment, instruments, communication devices and other fields. For example, they can be used in On vehicles, the typical applications on vehicles include electric sunroof, cooling fan, lamp control, oil pump control, horn control, A / C compression clutch control and other circuits, which play the role of switching circuit current and controlling circuit on and off. [0003] Electromagnetic relays in the prior art usually include lead pins and bases, wherein the lead pins include coil lead pins, moving contact lead pins and static contact lead pins, each lead pin is respectivel...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a lead-out pin, a plug-in electromagnetic relay and an assembly method thereof, through the improvement of the structure of the lead-out pin and the improvement of the connection structure between the lead-out pin of the coil and the coil terminal, On the one hand, it solves the problem that the fit between the lead-out pin and the base is prone to loosening in the thickness direction, the tolerance requirements for the fit between the base and the lead-out pin are very strict, and the processing cost of the parts is high; on the other hand, it solves the problem of coil lead-out pin and coil wiring When the column adopts a spot welding connection structure, it is necessary to punch the spot welding position of the coil lead out, resulting in a large size of the spot welding position of the coil lead out and a waste of material
