Abstract

The invention discloses an anti-loosening type static terminal structure of an electromagnetic relay. The anti-loosening type static terminal structure comprises a conductive metal sheet, the lower end surface of the conductive metal sheet is provided with an integrated-molding terminal pin, the front end surface of the terminal pin is provided with a plurality of blind glue holes distributed at intervals from the top, the front end surface and the rear end surface of the conductive metal sheet are provided with positioning strips in symmetry, the positioning strips are semi-tapered columns downwardly and gradually becoming smaller from the upper end surface of the conductive metal sheet, the conductive metal sheet between the two positioning strips is provided with a tapered filling hole, expansion fillers are filled in the tapered filling hole, and outer walls of the positioning strips are uniformly provided with a plurality of through holes communicated with the tapered filling hole. According to the anti-loosening type static terminal structure, the structure and the design are novel, the soundness and stability of the integral body of the static terminal and a base after the completion of installation can be improved via the reasonable design of barbs, the blind glue holes, the positioning strips, and the expansion fillers etc. on the terminal pin, and the service lifetime is extended.

Description

A kind of static terminal structure of locking ejector half electromagnetic relay
Technical field
The present invention relates to electromagnetic relay field, particularly relate to a kind of static terminal structure of locking ejector half electromagnetic relay.
Background technology
Existing market the static terminal of electromagnetic relay relative with the structural strength between pedestal on the weak side, in the long-time course of normal operation of relay, static terminal can because movable contact spring and static contact spring piece reciprocating collision, bond strength between static contact spring piece and pedestal is reduced, cause static terminal to loosen from pedestal, even come off.
Summary of the invention
The object of this invention is to provide a kind of static terminal structure of locking ejector half electromagnetic relay, the stability after its installation and anti-loosening performance are obviously promoted, and extend useful life.
Technical scheme of the present invention is as follows:
The static terminal structure of locking ejector half electromagnetic relay, it is characterized in that: comprise conductive metal sheet, the lower surface of conductive metal sheet is provided with integrated terminal pins, the front end face of terminal pins is provided with several blind glue holes spaced apart between upper, front end face and the rear end face of conductive metal sheet are arranged with positioning strip, positioning strip is the half-cone post diminished gradually downwards from conductive metal sheet upper surface, conductive metal sheet between two positioning strips is provided with taper filler opening, intumescent filler thing is filled with in taper filler opening, positioning strip outer wall evenly offers several through holes be connected with taper filler opening, the conductive metal sheet of the side of described positioning strip is also provided with contact holes
The static terminal structure of described locking ejector half electromagnetic relay, is characterized in that: the front-rear side walls that described terminal pins is relative is arranged with back-off, and back-off is near the afterbody of terminal pins.
The static terminal structure of described locking ejector half electromagnetic relay, is characterized in that: the position of described taper filler opening is corresponding with positioning strip, and the degree of depth is not less than positioning strip length.
Advantage of the present invention:
Novel in structural design of the present invention, by the back-off in terminal pins, blind glue hole, positioning strip, the isostructural appropriate design of intumescent filler thing, after making overall static terminal and pedestal installation, fastness and stability get a promotion, and extend useful life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
See Fig. 1:
The static terminal structure of locking ejector half electromagnetic relay, comprise conductive metal sheet 1, the lower surface of conductive metal sheet 1 is provided with integrated terminal pins 2, the front end face of terminal pins 2 is provided with several blind glue holes 3 spaced apart between upper, can prior drop part glue in a pre-installation, raising intercalation is arranged on compactness and the fastness of the contact after pedestal, the front end face of conductive metal sheet 1 and rear end face are arranged with positioning strip 4, positioning strip 4 is the half-cone post diminished gradually downwards from conductive metal sheet upper surface, conductive metal sheet 1 between two positioning strips 4 is provided with taper filler opening 5, intumescent filler thing 6 is filled with in taper filler opening 5, positioning strip 4 outer wall evenly offers the through hole 7 that several are connected with taper filler opening, intumescent filler thing 6 can part be escaped out after expanded by heating from through hole 7, compactness between pedestal is improved, the conductive metal sheet of the side of positioning strip 4 is also provided with contact holes 8.
The front-rear side walls that terminal pins 2 is relative is arranged with back-off 9, and back-off, near the afterbody of terminal pins, can effectively prevent from coming off after installation.
The position of taper filler opening 5 is corresponding with positioning strip 3, and the degree of depth is not less than positioning strip 3 length.
