Description
Technical field
The utility model relates to a kind of thermostat, is a kind of double-contact thermostat specifically.
Background technology
Thermostat, as a kind of switch, is widely used in various electrical equipment.Thermostat is the through and off that promote contact with pressure-acting principle, thus the electric equipment that control apparatus equipment stops or starting working in the time reaching uniform temperature.
But the movable contact spring of existing thermostat is provided with a contact, this single contact structural reliability is low, poor stability; In addition product entirety is square structure, and shock resistance is poor, antivibration moment; In assembling process, be not suitable for automation Assembling Production, production efficiency is low.
Summary of the invention
The utility model is exactly that existing thermostat single contact structural reliability is low, poor stability in order to solve, product entirety is that square structure shock resistance is poor, antivibration moment, in assembling process, be not suitable for automation Assembling Production, technical problem that production efficiency is low, the double-contact thermostat that provide that a kind of reliability is high, good stability, strong shock resistance, anti-vibration ability are strong, be applicable to automation assembling, production efficiency is high.
The technical solution of the utility model is, a kind of double-contact thermostat is provided, and the terminal that it comprises pedestal, Ji Gai, seal closure and is located at pedestal two ends, is provided with the movable contact spring and the static contact that are in contact with one another in pedestal, and terminal is connected with movable contact spring, static contact; In the middle of base lid, be provided with circular hole, be provided with guide rod in circular hole, lower end of the guide rod portion contacts with movable contact spring, between lower end of the guide rod portion and seal closure, is provided with bimetal leaf, and movable contact spring and static contact are equipped with two contacts.
Preferably, two contacts are the arrangement of U font.
The beneficial effects of the utility model are, single contact structural reliability is high, good stability, and product entirety is that rectangular structure strong shock resistance, anti-vibration ability are strong, are applicable to automation Assembling Production, production efficiency is high in assembling process.
The further feature of the utility model and aspect, by the description of the embodiment below with reference to accompanying drawing, clearly recorded.

Embodiment
Referring to accompanying drawing, with specific embodiment, the utility model is described in further detail.
As shown in Figure 1, double-contact thermostat of the present utility model comprises by the terminal 4 at pedestal 1, base lid 2, seal closure 3 and pedestal two ends and forming, in pedestal 1, be provided with movable contact spring 5 and static contact 6, movable contact spring 5, static contact 6 are in contact with one another, and terminal 4 is connected with movable contact spring 5, static contact 6; In the middle of base lid 2, be provided with circular hole, insert guide rod 7 in circular hole, guide rod 7 bottoms contact with movable contact spring 5, and bimetal leaf 8 is located between guide rod 7 bottoms and seal closure 3.
As shown in Fig. 3,4,5,6,7, movable contact spring 5 is provided with two contacts, is respectively contact 9 and contact 10.These two contacts are U font and arrange.Static contact 6 is also provided with two contacts of mating with movable contact spring 5 accordingly, and these two contacts are also U font and arrange.
As shown in Figure 2, in the time that bimetal leaf 8 senses that ambient temperature reaches certain value, bimetal leaf 8 can deform, and guide rod 7 promotes movable contact spring 5 under the pressure-acting of bimetal leaf 8, and movable contact spring 5, static contact 6 are separated, and now thermostat is in off-state.
Product entirety is that rectangular structure strong shock resistance, anti-vibration ability are strong.
