Electromagnetic relay with anti-short circuit function

Abstract

The invention discloses an electromagnetic relay with an anti-short circuit function, which comprises a base and a contact portion, wherein the contact portion includes a moving reed assembly; the moving reed assembly includes a moving reed leading-out piece, a moving reed and a moving contact; the moving contact is fixed at one end of the moving reed; the moving reed leading-out piece is installed on the base; the moving reed leading-out piece is provided with a bend, the tail end of one side of the bend of the moving reed leading-out piece is fixed with the moving reed and enables the movingreed leading-out piece and the moving reed to form V-shaped distribution so as to realize an anti-short circuit function; the other side of the bend of the moving reed leading-out piece passes through the base and further extends downward to form a moving reed leading-out pin; the moving reed leading-out piece is provided with a downward opening at the bend; and at the opening, one side of the bend of the moving reed leading-out piece further straightly extends forward from the middle lower section of the opening to form a first boss. The electromagnetic relay disclosed by the invention not only can prevent the moving reed leading-out piece from inclining outward due to the effect of electric power, but also can effectively improve the strength of the base.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to an electromagnetic relay with an anti-short circuit function. Background technique [0002] An electromagnetic relay with anti-short-circuit function in the prior art is to set the moving spring assembly of the contact part in a V shape to realize the anti-short circuit function. figure 1 It is a structural schematic diagram of the contact part of an electromagnetic relay with anti-short circuit function in the prior art. The contact part includes a moving spring assembly and a static spring assembly. The static spring assembly includes a rigid static spring piece 100 and a static contact 101. The contact 101 is fixed on one end of the static reed 100, and the other end of the static reed 100 extends out of the base as the lead-out pin 102 of the static spring. The moving spring assembly includes a rigid moving spring lead-out 200, a flexible moving reed 201 and The movable conta...

Problems solved by technology

In the electromagnetic relay of this structure, the electric repulsion force generated between the moving spring lead-out piece 200 and the moving reed 201 will also act on the moving spring lead-out piece 200 at the same time, causing the moving spring lead-out piece 200 to tilt outward, thereby affecting the relay. performance

On the other hand, this short-circuit resistant electromagnetic relay cannot improve the strength of the base by increasing the wall thickness of the base due to the influence of the external dimensions of the relay and the distribution of internal components, resulting in insufficient strength of the base and affecting the relay. service life
