Abstract
The utility model provides a reverse-support temperature protector. The reverse-support temperature protector comprises an insulating casing, a static contact piece, a reverse support, a supporting block, a temperature piece and a movable contact connected to one end of the temperature piece. The reverse support is fixed on an internal upper surface of the insulating casing via the supporting block, the other end of the temperature piece is fixed between the supporting block and the reverse support, the static contact piece is contacted with the movable contact, and the static contact piece, the temperature piece and the reverse support are conductors. The temperature piece is fixed on the internal upper surface of the insulating casing, and the static contact piece is near an internal lower surface of the insulating casing, so the temperature piece has a sloping structure. The temperature piece can be welded on the reverse support first, and then the static contact piece and a plug block are fixed in production, so difficulty of processing can be reduced. And the reverse support can be supported only by one plug block, and a motion space of the temperature piece can be fully used, so the overall thickness of the protector is obviously reduced.
Description
Technical field
The utility model relates to the electric prospection field, specially refers to a kind of temperature protector.
Background technology
The temperature protector of application, with reference to accompanying drawing 1, mainly comprise pedestal, silver strip assembly (static contact), temperature bimetal leaf, moving contact and shell at present.It generally all adopts riveting technology, said modules is riveted into as a whole.When moving contact contacts with the silver strip assembly, the whole conducting of circuit; When electrical equipment makes temperature rise to the operating temperature of temperature protector because of heating; shell is heated and conducts to bimetal leaf; bimetal leaf is heated and produces internal stress and action rapidly, thereby moving contact leaves static contact silver strip assembly and open circuit, thereby cut off appliances power source, plays a protective role.When protected electrical equipment temperature drops to the specified reset temperature value of temperature protector, the temperature bimetal leaf returns to initial contact condition, and electrical equipment recovers normal operation.Yet, existing temperature protector is because the thermometer in internal structure is designed to and the base bottom surface almost parallel, thereby cause when making product, after first needing to be fixed on pedestal by static contact, rivet again thermometer, and riveted joint when thermometer because its space is little, and closed encirclement, thereby difficulty of processing is large; Have again, support because support needs the two sides of section in the enclosure, thereby thickness can't effectively reduce, thereby the integral thickness of protector is partially thick.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of design that automaton is made that is beneficial to, and can obviously reduce the structure of temperature protector thickness simultaneously.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Reverse backing temp protector; comprise insulation crust, static contact, oppositely support, back-up block, with the thermometer of temperature bending be connected in the moving contact of thermometer one end; the fixing reverse support of described back-up block is in the upper surface of insulation crust inside; fix the other end of described thermometer between back-up block and reverse support; the front end of described static contact contacts with moving contact, and described static contact, thermometer and reverse support are conductor.
As further describing above-mentioned reverse backing temp protector; it also comprises chock; the top and bottom of chock props up respectively the lower surface of reverse support and insulation crust inside; static contact is fixed on the bottom of chock, and the contact point of static contact and moving contact is lower than the contact point of reverse support and thermometer.
As a kind of preferred version, described thermometer is welded on reverse support.
As to the further describing of above-mentioned reverse backing temp protector, the end of static contact and the end of reverse support respectively connect a wire and near the same side of insulation crust inside.
As a kind of preferred version, described moving contact is silver contact.
The beneficial effects of the utility model are: because thermometer is installed on the upper surface of insulation crust inside, static contact is close to the lower surface of insulation crust inside, thereby the thermometer structure that is an inclination, when making, can first thermometer be welded on reverse support, again static contact and chock are fixed, so can reduce the mach difficulty of assembling, and the step of production is simple, and quality can be guaranteed; Simultaneously, oppositely support only need utilize a chock to be supported, and the space of thermometer also obtains maximum using, and the integral thickness for protector has just had significantly and reduced like this.
The accompanying drawing explanation
The overall structure figure that Fig. 1 is the conventional temperature protector;
Fig. 2 is overall structure figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
As shown in Figure 2; reverse backing temp protector; comprise insulation crust 1, static contact 2, oppositely support 3, back-up block 4, with the thermometer 5 of temperature bending be connected in the moving contact 6 of thermometer 5 one ends; the fixing reverse support 3 of described back-up block 4 is in the upper surface of insulation crust inside; fix the other end of described thermometer 5 between back-up block and reverse support; the front end of described static contact 2 contacts with moving contact 6, and described static contact, thermometer and reverse support are conductor.
As further describing above-mentioned reverse backing temp protector; it also comprises chock 7; the top and bottom of chock props up respectively the lower surface of reverse support 3 and insulation crust 1 inside; static contact is fixed on the bottom of chock, and the contact point of static contact 2 and moving contact 6 is lower than the contact point of reverse support and thermometer.
As a kind of preferred version, described thermometer 5 is welded on reverse support 3.
As to the further describing of above-mentioned reverse backing temp protector, the end of the end of static contact 2 and reverse support 3 respectively connects a wire 8 and near the same side of insulation crust inside.
As a kind of preferred version, described moving contact 6 is silver contact.
During this temperature protector specific works, thermometer 5 is in free state, and moving contact contacts closed with the fixed contact of static contact 2, circuit turn-on.The current heating that makes temperature rise to the operating temperature of temperature protector when electrical equipment because of heating or pass through is during to the operating temperature of temperature protector; described thermometer 5 is heated and produces internal stress and upwards bending of action rapidly; the moving contact that makes to be welded on thermometer one end disconnects and contacting with static contact; the circuital current that disconnects contact disconnects; thereby cut off the power supply of electrical equipment, play the too high protective effect of heating temp.When protected electrical equipment temperature drops to the specified reset temperature value of described temperature protector, thermometer will be followed the decline of temperature and be resiled, and moving contact and static contact return to initial contact condition, and electrical equipment recovers normal operation.
The above not imposes any restrictions this novel technical scope, and all any modification, equivalent variations and modifications of above embodiment being done according to the utility model technical spirit all still belong in the scope of this novel technical scheme.
