The insulator of the base has two connecting posts stretching into the body, and the side of the body of the housing has a contact point. The inside the body of the housing has a fixed support, and has a thermistors board fixed on one side of the support at both sides of the bottom of the fixed moving contact. An sheet of the adjusting pressure is equipped on the top of the housing body, while one side of the sheet is pressed on the surface of the of thermistors board. The advantage of the invention is having a support to help carry sums of the load, and is having the ability to adjust the sensibility of the thermistors with high speed, so as to increase the service life and effects of the protection.

Technical field
The utility model relates to a kind of to the compressor compressor of air conditioner thermal protector protected during too high and current overload in temperature of compressor of air conditioner coil particularly.
Background technology
Thermal protector for protection compressor coil in the prior art is a lot; its technology is also ripe; but when inserting thermal protector in the compressor circuit in the prior art; owing to himself structural reason; assembling is complicated on the one hand; on the other hand temperature-sensitive plate (also being bimetal leaf) operating time in the protector or work number of times more for a long time, its intensity, sensitivity meeting reduce, and influence protector result of use and useful life.
Summary of the invention
The purpose of this utility model is a kind of simple in structure and compressor of air conditioner thermal protector that can efficiently use for a long time of design.
The technical scheme that realizes the utility model above-mentioned purpose is: the compressor of air conditioner thermal protector; has a base; be fixed with on the base housing and and base between form a housing chamber; insulation is fixed with two binding posts on the base; binding post stretches in the housing chamber; it is characterized in that: binding post stretches into the endoceliac end of shell and is fixed with fixed contact; housing chamber internal fixation has supporting plate; also have both sides, a below and be fixed with the temperature-sensitive plate of moving contact; one side of temperature-sensitive plate is fixed on a side of supporting plate; the corresponding setting of moving contact with fixed contact, the inner walls of housing top of chamber is provided with the pressure regulation sheet, and the pressure regulation sheet has an end to be pressed in the upper surface of temperature-sensitive plate.
Aforesaid supporting plate one end is fixed on inner walls, and other end insulation is fixed on the inner walls opposite side, and a side of temperature-sensitive plate is fixed on the end that insulation is fixed on the supporting plate of inner walls.
According to aforesaid technical scheme, described supporting plate can also be, it is " Z " font, on the base upper surface that is fixed on below, housing chamber of its lower end, and meanwhile its upper end the end and a side of temperature-sensitive plate be fixedly connected.
Further, be fixed with a support on the base upper surface of below, housing chamber opposite side, hold to the upper end insulation of support the position that temperature-sensitive plate and supporting plate are fixedly connected.
Further, also has arbitrary position that a lead is fixed on housing outer wall or base lower surface conductively.
The utility model has the advantages that protection, have supporting plate to help temperature-sensitive plate carrying certain load, the sensitivity of pressure regulation sheet high speed temperature-sensitive plate is arranged, therefore improved the useful life and the effect of protector greatly applicable to cooler compressor in the three-phase current circuit.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is the structural representation of embodiment one
Fig. 2 is the schematic side view of Fig. 1;
Fig. 3 is the structural representation of embodiment two;
Fig. 4 is the schematic side view of Fig. 4.
Among the figure, 1 is housing, and 2 is base, and 3 is the housing chamber, and 4 are the pressure regulation sheet, and 5 is binding post, and 51 is fixed contact, and 6 is supporting plate, and 7 is the temperature-sensitive plate, and 71 is moving contact, and 61 is support, and 8 is lead.
Embodiment
Embodiment one: be fixed with on the base 2 of compressor of air conditioner thermal protector a housing 1 and and base between form a housing chamber 3; insulation is fixed with two binding posts 5 and is welded with lead 8 on the base 2; binding post 5 stretches in the housing chamber 3; its end of stretching in the housing chamber 3 is fixed with fixed contact 51; housing chamber 3 internal fixation have supporting plate 6; also have both sides, a below and be fixed with the temperature-sensitive plate of making by bimetal leaf 7 of moving contact 71; one side of temperature-sensitive plate 7 is fixed on a side of supporting plate 6; moving contact 71 and fixed contact 51 corresponding settings; housing 1 inwall at 3 tops, housing chamber is provided with pressure regulation sheet 4, and the leading section of pressure regulation sheet 4 is pressed in the upper surface of temperature-sensitive plate 7.
One end of supporting plate 6 is fixed on housing 1 inwall, and other end insulation is fixed on housing 1 inwall opposite side, and a side of temperature-sensitive plate 7 is fixed on the end that insulation is fixed on the supporting plate 6 of housing 1 inwall.
When temperature was too high, heat reached supporting plate by the housing outer wall and passes to the temperature-sensitive plate again, and the tripping because of the characteristics of bimetal leaf of temperature-sensitive plate disconnects moving contact and fixed contact, thereby circuit is disconnected; When otherwise temperature is hanged down, moving contact and fixed contact are connected circuit is connected.When the sensitivity of temperature-sensitive plate reduced, the intensity of pressing to the temperature-sensitive plate by the adjusting regulator board made temperature-sensitive satisfy working sensitivity.
Embodiment two:
Be fixed with on the base 2 housing 1 and and base between form a housing chamber 3, insulation is fixed with two binding posts 5 and is welded with lead 8 on the base 2, binding post 5 stretches in the housing chamber 3, its end of stretching in the housing chamber 3 is fixed with fixed contact 51, housing chamber 3 internal fixation have supporting plate 6, also have both sides, a below and be fixed with the temperature-sensitive plate of making by bimetal leaf 7 of moving contact 71, one side of temperature-sensitive plate 7 is fixed on a side of supporting plate 6, moving contact 71 and fixed contact 51 corresponding settings, housing 1 inwall at 3 tops, housing chamber is provided with pressure regulation sheet 4, and the leading section of pressure regulation sheet 4 is pressed in the upper surface of temperature-sensitive plate 7.
Supporting plate 6 is " Z " font, on base 2 upper surfaces that are fixed on 3 belows, housing chamber of its lower end, and meanwhile its upper end the end and a side of temperature-sensitive plate 7 be fixedly connected.
Be fixed with a support 61 on base 2 upper surfaces of housing chamber 3 below opposite sides, the position that temperature-sensitive plate 7 and supporting plate 6 are fixedly connected is held in the upper end of support 61.
