Abstract
The utility model relates to an automobile air-conditioning system pressure controller, which comprises a switching body(1). The toe of the switch body(1) is cavity-shaped. A contact switch(2) is arranged in the cavity. The contact switch(2) is connected with a connecting wire(3). The toe of the contact switch(2) is provided with a pressure conductor(4). The pressure conductor(4) is connected with a flexible film(5). The utility model is characterized in that a sealed cavity is formed through pressure wading and fixing of the toe of the switch body(1) and the top end of an integrated pressure cavity(6). With an integrated pressure wading method and multi-sealing devices used in the utility model, the possibility of the leaking of a condensate is reduced; the passing rate of the product is increased. With high-temperature welding and pickling chemical processing, the processing is simplified and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of pressure controller that is used for automotive air-conditioning system.
Background technology
The pressure controller of the use in the automotive air-conditioning system is that the operation principle of pressure switch is according to shell unstability displacement principle, to approach stainless steel and make definite shape, size by control corrosion resistant plate die cavity, make its unstability under the pressure of setting, by the strength conduction device distortion of stainless steel shell is passed to pair of contact in the circuit again, thereby the break-make of control circuit finally reaches the effect of control compressor or temperature-dropping fan.
Present pressure switch at first is to be that solder flux is integrally welded by oxy-acetylene welding be threaded body and stainless steel pressure chamber with the silver soldering pricker, again it is carried out the chemical pickling surface treatment, and then this weldment and thin stainless steel shaped resilient element and Switch main body retainer plate be welded into integral body once more by argon arc welding, forms the pressure chamber of an integral body.But this pressure switch has following several defective:
1, since in the pressure chamber with cold-producing medium as pressure source, and the penetration of cold-producing medium is more intense, the welding position welding quality time then can cause freezing medium leakage slightly, causes scrapping of part.
2, because this part is handled through twice high-temperature soldering and chemical pickling once during fabrication, can make the material of part that some variations take place, so just influence the stability of part action and the dimensional accuracy of each parts of part joint screw thread.
3, because of adopt oxy-acetylene welding processing in manufacture process, its surface oxidation need carry out outward appearance reprocessing, increases production cost.
Summary of the invention
The purpose of this utility model then is at above-mentioned the deficiencies in the prior art, and a kind of automotive air-conditioning system pressure controller is provided, and it is simple in structure, production cost is low and difficult generation freezing medium leakage.
The purpose of this utility model can realize by following measure:
A kind of automotive air-conditioning system pressure controller, comprise Switch main body 1, Switch main body 1 lower end is the cavity shape, establish contact switch 2 in the cavity, contact switch 2 connects lead 3, and the below of contact switch 2 is provided with pressure conducting piece 4, is connected with elastic strip body 5 on the pressure conducting piece 4, it is characterized in that Switch main body 1 lower end and holistic pressure cavity 6 upper ends fix by mechanical crimping, form the cavity of a sealing.
The purpose of this utility model can also realize by following measure:
The cavity inner wall lower end of described Switch main body 1 is provided with seal A, and described seal A adopts film.
The cavity inner wall lower end of described Switch main body 1 is provided with seal B, and described seal B can adopt rubber seal.
The beneficial effects of the utility model:
Owing to adopted the integral way crimping, and adopted multinomial sealing setting, reduced the possibility that condensing agent leaks, improved rate of finished products.Handle because cancelled high-temperature soldering and chemical pickling, simplified manufacturing procedure, reduced production cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of existing pressure switch.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, the pressure cavity 6 that is connected Switch main body 1 below is an integral body, and what do not resemble the existing product employing is two modes that cavity welds with oxycetylene, the so just leakage that can not produce condensing agent up and down.Switch main body 1 is connected by the crimping mode with pressure cavity 6, and they form the cavity of a sealing, and their mechanical crimping point 7 is in the shell of whole device, ensures the sealing of whole device.Switch main body 1 lower end is the cavity shape, establishes contact switch 2 in the cavity, and contact switch 2 connects lead 3, and lead 3 connects other electric device.The below of contact switch 2 is provided with pressure conducting piece 4, and pressure conducting piece 4 adopts plastics to make, and the projection of its upper end passes elastic strip body 5 and leans on contact switch 2.The elastic force that pressure conducting piece 4 will overcome elastic strip body 5 when the pressure of pressure conducting piece 4 belows becomes big makes contact switch 2 closures, thereby connects warning circuit.Below pressure conducting piece 4, be provided with seal A, what adopt here is film, its periphery is pressed in the cavity inner wall lower end of Switch main body 1, below it, also be provided with simultaneously seal B, seal B can adopt rubber seal, has so more strengthened the sealing of 6 of Switch main body 1 and pressure cavity.Above-mentioned elastic strip body 5 is the stainless steel flexure strip, and adopts multi-disc elastic strip body 5 to be used in combination according to the big I of concrete pressure that condensing agent produces.
The undeclared part that the utility model relates to is same as the prior art or adopt prior art to add realization.
Claims (5)
