Background technology

Compressor protector has another name called the temperature-sensitive protection relay, is to utilize the characteristics design of thermosensitive bimetal or three sheet metals to form.It can be installed on the surface of the compressor of air-conditioning or other electroheat equipment; connect with the compressor clutch circuit, when compressor breaks down or runs into other reason and overtemperature occurs, the counter-rotating of protector thermosensitive bimetal moment kick; cut off circuital current, the protection compressor is unlikely to overtemperature and destroys.Common compressor protector adopts external mostly, mainly be installed on compressor surface and do overtemperature protection, yet the external protector damage easily, to occupy redundant space during installation, poor work stability under mal-condition.Compressor Built-in Protector has appearred for this reason; the patent No. is that the Chinese utility model patent of ZL 200420054412.5 discloses a kind of Compressor Built-in Protector; it includes two conducting rods of drawing from protector, and one is electrically connected inserted sheet, another electrical connection contact sleeve.The internal structure of this kind protector design more complicated, and the position that makes protector be arranged on the compressor inner space owing to the fixed position of two conducting rods also has limitation.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of Compressor Built-in Protector, and it is simple in structure, cost is low, and can be installed on each position of compressor inside according to demand easily.

For reaching above-mentioned purpose; the technical solution of the utility model is achieved in that Compressor Built-in Protector of the present utility model comprises pedestal; be installed on the protector unit on the described pedestal; be connected sleeve and inserted sheet on the described protector unit; described protector unit comprises shell; be sealed with substrate on the described shell and form accommodation space; be provided with the thermal response plate in the described accommodation space; described thermal response plate one end fixedly is electrically connected by affixed assembly with described outer casing inner wall; the other end of described thermal response plate fixedly is electrically connected with moving contact; corresponding described moving contact also is provided with fixed contact; described fixed contact fixedly is electrically connected with the still that can fuse; be inserted with the binding post that an end fixedly is electrically connected with described still on the described substrate in described accommodation space; by the electrical insulating material sealing and fixing, isolate by insulation board between described substrate and the described still between described binding post and the described substrate.

The other end that described binding post exposes described substrate is electrically connected with described sleeve, and described substrate is electrically connected with described inserted sheet.

Described shell and described pedestal are made by the metal material that conducts electricity very well.

Described affixed assembly is the weldering nail.

Described thermal response plate is bimetal leaf or three sheet metals.

As shown from the above technical solution, adopt of the present utility model and beneficial effect that obtain is: utilize a binding post and substrate to replace two binding posts in original technology, the installation site of inserted sheet is arbitrarily adjusted according to the compressor inner space, and it is simple in structure, reduced manufacturing cost, applicability is wide, good reliability.

Embodiment

The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 4; Compressor Built-in Protector of the present utility model comprises pedestal 1; protector unit 2 is installed on pedestal 1, and this protector unit 2 is connected with sleeve 3 and inserted sheet 4, by sleeve 3 and inserted sheet 4 protector of the present utility model is fixedly placed in the compressor.

As shown in Figure 1, protector unit 2 comprises shell 5, be sealed with substrate 6 on the shell 5 and between shell 5 and substrate 6, be formed with accommodation space, be provided with thermal response plate 7 in this accommodation space, this thermal response plate 7 can be bimetal leaf or three sheet metals, and shell 5 is made by the metal material that conducts electricity very well with pedestal 6; One end of thermal response plate 7 fixedly is electrically connected by affixed assembly 8 with the inwall of shell 5, and this affixed assembly 8 can be the weldering nail, not as limit; The other end of thermal response plate 7 fixedly is electrically connected with moving contact 9, shown in Fig. 2 A, Fig. 2 B; In conjunction with shown in Fig. 3 A, Fig. 3 B, in accommodation space, corresponding moving contact 9 also is provided with fixed contact 10 again, and this fixed contact 10 fixedly is electrically connected with the still 11 that can fuse, and at high temperature, still 11 can carry out fuse protection.Be inserted with the binding post 12 that an end fixedly is electrically connected with still 11 on the substrate 6 in accommodation space, pass through electrical insulating material 14 sealing and fixing between this binding post 12 and the substrate 6; Isolate by insulation board 13 between substrate 6 and the still 11.Realized by the series circuit of binding post 12 by above structure to substrate 6.

Consult Fig. 4 to Fig. 7 again, binding post 12 exposes the other end electrical connection contact sleeve 3 of substrate 6, and substrate 6 directly is electrically connected inserted sheet 4.Protector of the present utility model has replaced second binding post of the protector of original technology with substrate 6, make substrate 6 more diversified with the link position of inserted sheet 4, and inserted sheet 4 contacts with substrate 6 surperficial optional positions can form the electrical connection circuit.Fig. 4 to Fig. 7 is the schematic diagram of four embodiment of Compressor Built-in Protector of the present utility model; enumerated respectively that inserted sheet 4 is electrically connected with the surperficial diverse location of substrate 6 and the exterior structure of the Compressor Built-in Protector of the present utility model formed, applicable to the demand of different compressors inside installing space.And, also simplified the manufacturing process and the cost of protector greatly owing to the setting that has reduced by a binding post than the protector of original technology.

Therefore, Compressor Built-in Protector of the present utility model has following advantage:

1, by binding post 12 be electrically connected with sleeve 3, substrate 6 is electrically connected with inserted sheet 4, simplified the labyrinth and the processing technology that have two binding posts in the prior art.
