Abstract
The utility model provides a temperature detect switch used for cars, which comprises a post head, an insulating closing ring, an insulating body, a shell body, a connection shaft of a breakback contact, a moving contact, a bimetallic heat-variable piece and a bowl-shaped spring, wherein the connection shaft with a breakback contact on the top is embedded into an inner hole of the insulating body after being connected with the post head; the insulating closing ring is arranged in the extension outside the insulating body and the bowl-shaped spring is arranged in the lug boss in one top head of the inner hole of the shell; the trochoid spiral bimetallic heat-variable piece contacts with the bowl-shaped spring and the moving contact is arranged in the position corresponding to the breakback contact of the bimetallic heat-variable piece, which makes the bimetallic heat-variable piece have an overturn mutation in regulated temperatures, and thus the moving contact connect with or cut from the breakback contact instantaneously and thus the switch is formed. The utility model has a skillfully and reasonably designed structure; the contacting or the cutting of the switch is sensitive and reliable and the production cost of the design is low.
Description
Technical field
The utility model belongs to coolant-temperature switch, particularly a kind of car temperature switch device.
Background technology
The coolant-temperature switch of widespread usage in existing mid-get car adopts housing interior filling bronze and paraffin to expand touch switch to form switching device with temperature.Yet this unit temp control is unstable; Materials used cost height; The manufacturing process complexity; The factor that influences product design is many.
Technology contents
The purpose of this utility model provide a kind of simple in structure, product reliability is strong, the car temperature switch device of stable temperature control.
The technical solution of the utility model is: a kind of car temperature switch device is characterized in that: it is made up of adapter shaft, moving contact, composite metal heat-sensitive sheet and the conical helical spring of binding post, insulation back-up ring, insulator, housing, break back contact; The adapter shaft that the top has break back contact is connected with binding post in the back embedding insulator endoporus, its insulator exterior protrudes out device insulation back-up ring, conical helical spring is installed on the boss on housing endoporus top, bowl-type composite metal heat-sensitive sheet contacts with conical helical spring, bowl-type composite metal heat-sensitive sheet top, corresponding break back contact position is provided with moving contact, make bowl-type composite metal heat-sensitive sheet that the upset sudden change take place in the temperature of regulation, make that the movable contact electricity is instantaneous to be connected with break back contact or to disconnect, form switch.
Above-mentioned moving contact and break back contact distance are controlled between the 0.05mm.
Above-mentioned moving contact is made of silver contact and phosphor-copper spring leaf.
The beneficial effects of the utility model are: structure design is ingenious rationally, and being switched on or switched off of switch is sensitive reliable, and design cost is cheap.
Description of drawings
Fig. 1 structural representation of the present utility model.
Among the figure: 1 binding post, 2 insulation back-up rings, 3 insulators, 4 housings, the adapter shaft of 5 break back contacies, 6 moving contacts, 7 composite metal heat-sensitive sheets, 8 bowl-type springs, 9 contacts, 10 phosphor-copper spring leafs.
The specific embodiment
Specify the utility model below in conjunction with drawings and Examples.
A kind of car temperature switch device, it is by binding post 1, insulation back-up ring 2, insulator 3, housing 4, the adapter shaft 5 of break back contact, moving contact 6, composite metal heat-sensitive sheet 7 is formed with bowl-type spring 8: the adapter shaft 5 that the top has break back contact is connected with binding post 1 in back embedding insulator 3 endoporus, its insulator 3 outsides protrude out device insulation back-up ring 2, bowl-type spring 8 is installed on the boss on housing 4 endoporus tops, trochoid spiral composite metal heat-sensitive sheet 7 contacts with bowl-type spring 8, installs by silver contact 9 and phosphor-copper spring leaf 10 on the trochoid spiral composite metal heat-sensitive sheet 7 of position within the corresponding break back contact 0.05mm to constitute moving contact 6.
Principle of work: the housing of car temperature switch device is a negative pole, and binding post is anodal, and moving contact is connected with the housing that connects negative pole with bow type spring.Within 0.05mm, when the composite metal heat-sensitive sheet overturns, make that the movable contact electricity is instantaneous to be connected with break back contact or to disconnect the formation switch with the distance and position of composite metal heat-sensitive sheet control moving contact in the temperature of regulation.
Claims (3)
