Abstract

An endurance environmental temperature relay comprises a long wiring foot, a short wiring foot, a glass insulator, a bushing, a mounting plate, a static support plate, a bimetallic plate, a push column, a dynamic contact chip and a dynamic support plate. All components are arranged in a cavity composed of a cove and a base plate; the long wiring foot and the short wiring foot extend out of the base plate, thereby forming the whole body of the relay; a ceramic plate and a flash ceramic plate are arranged respectively between the upper surface and the lower surface of the glass insulator as well as between the long wiring foot and the short wiring foot. The utility model with the advantages of long service life, vibration resistance, shock resistance and high insulation index is applicable to the occasions requiring high endurance environment.

Description

Endurance ambient temperature relay

One, technical field

The utility model relates to a kind of endurance ambient temperature relay, belongs to the electronic devices and components that temperature control and overtemperature protection are used.

Two, background technology

Along with the develop rapidly of science and technology, industrial products are more and more higher to the requirement of component reliability and environmental suitability, for this also has higher requirement to temperature relay life-span, endurance environment capacity.At present, on a lot of military use products, though the seal temperature relay can satisfy these requirements, the product structure more complicated, quality control requirement is also very strict.In the seal temperature relay of industrial controlling, it guarantees insulation with glass insulator and air gap, and environmental index such as proof voltage can't satisfy actual instructions for use again.Therefore be necessary to propose a kind of novel product structure, satisfy the environmental suitability of seal temperature relay.

Three, summary of the invention

The utility model is in order to solve above technical problem, the temperature relay of mechanical environments such as a kind of high insulation index, long-life, vibration resistance and impact to be provided.

For achieving the above object, endurance ambient temperature relay described in the utility model adopts following technical proposals:

This temperature relay comprises: long leg, short circuit stitch, glass insulator, lining, mounting panel, quiet supporting spring, bimetal leaf, promotion post, moving contacting plate, moving supporting spring, above-mentioned each part is packed into by in cover and the cavity formed of substrate, the length leg is stretched out substrate and is formed relay integral body outward, and potsherd and arc potsherd are set respectively between upper and lower surface of described glass insulator and long and short leg.

Adopt the seal temperature relay described in the utility model of said structure scheme to have the long-life, vibration resistance, impact, the advantage of insulation high target.

Five, embodiment

Below in conjunction with accompanying drawing the utility model is elaborated:

As shown in Figure 1, endurance ambient temperature relay described in the utility model comprises: long leg 2, short circuit stitch 1, glass insulator 4, lining 7, mounting panel 8, quiet supporting spring 9, bimetal leaf 11, promotion post 12, moving contacting plate 13, moving supporting spring 16, above-mentioned each part is packed into by in cover 6 and the cavity formed of substrate 5, mounting panel 8 is fixed on the lateral surface lower end of cover 6, long and short leg is stretched out the substrate 6 outer relay integral body of forming, and is respectively equipped with potsherd 3 and arc potsherd 17 between upper and lower surface of described glass insulator and long and short leg.

Utilize glass sintering technology together with glass insulator 4, short circuit stitch 1, long leg 2, potsherd 3, arc potsherd 17 sintering.Wherein potsherd 3 and arc potsherd 17 respectively sintering be bonded in glass insulator 4 upper and lower planes, by means such as chamferings, the contact area of control potsherd 3 and arc potsherd 17 and glass insulator self goes up lower plane less than glass insulator 4 before the sintering.

Moving contacting plate 13 is made as shallow disc shape, and in a plane, the center punching press forms a convex closure substantially, and this convex closure is placed on and promotes to form a lever dolly structure on the whole on the post 12.Moving contact 14 rivetings are contained on the moving contacting plate 13.Fixed contact 10 is contained on the quiet supporting spring 9 by rivet 15 rivetings.

Promote post 12 and make, promote post 12, in an inner lining 7, the intermediate projections long enough of lining 7, the stability of assurance promotion post 12 of installing of relay in order to fix for the ceramic material that insulate.
