Description

A kind of refrigerant compressor binding post

Technical field

The utility model relates to a kind of compressor, particularly relates to a kind of binding post of refrigerant compressor.

Background technology

The binding post of refrigerant compressor is that external power is transported to the vitals that compressor inside makes compressor operating.Traditional compressor is because sealing property and the insulation property of binding post are relatively poor, thereby when work, often make the inner entrained air of compressor and cause the too short or decreasing insulating generation low vacuum arcing of inboard conductive pole creepage distance, thereby cause the serious accident of compressor blast.

Summary of the invention

The technical problems to be solved in the utility model provide a kind of not only sealing property and insulation property good, thereby guarantee that the compression function works reliably, and refrigerant compressor binding post simple in structure.

For solving the problems of the technologies described above, the utility model adopts a kind of like this refrigerant compressor binding post, the rounded end cap of the cross section that this binding post is made by carbon steel, several column conductive poles of being made by ferrochrome and be made of the insulator that glass is made; Offer several through holes on the described end cap, described each conductive pole passes described through hole and is tightly connected by described insulator and this through hole, and described end cap is fixedly mounted on the shell of refrigerant compressor.

As a kind of improvement of the present utility model, this binding post also is provided with brace, and described brace is fixedly mounted on the end of each conductive pole through punching press.

Through hole on the utility model end cap preferably has three and uniform along the center line of end cap, and described conductive pole has three, and described through hole forms flange through punching press.

After adopting such structure, because glass insulator of the present utility model has good insulation property, be connected with end cap seal by described glass insulator owing to each conductive pole again, thereby binding post of the present utility model not only has good sealing property and insulation property, thereby guaranteeing to compress function works reliably, and simple in structure, make easy.

The utility model also is provided with brace, and after adopting impact style to be fixed on the end of each conductive pole the brace, on the one hand brace can be installed on the conductive pole more firmly, at conductive pole brace be installed on the other hand, power line is electrically connected with each conductive pole more reliably.

Through hole on the utility model end cap can make the contact area of glass insulator and through hole larger after adopting punching press to form flange, thereby makes insulation, sealing property better.

Embodiment

Referring to Fig. 1 to a kind of refrigerant compressor binding post shown in Figure 9, the rounded end cap 1 of the cross section that this binding post is made by carbon steel, several column conductive poles 2 of being made by ferrochrome and consisted of by the insulator 3 that glass is made; Offer several through holes 1-1 on the described end cap 1, described each conductive pole 2 passes described through hole 1-1 and is tightly connected with this through hole 1-1 by described insulator 3, and described end cap 1 is by being welded and fixed on the shell that is installed in refrigerant compressor.Shown in Fig. 3,4, end cap of the present utility model 1 is preferred, and to adopt phosphorus content be that 0.35～0.60% carbon steel sheet forms through punch process.As shown in Figure 1, 2, conductive pole 2 of the present utility model is the cylindrical conductive post.

Shown in Fig. 1,2,7,8,9, binding post of the present utility model preferably is provided with brace 4, and described brace 4 is fixedly mounted on the end of each conductive pole 2 through punching press.Adding man-hour, by becoming two arc groove tight fits of two arc convex 4-1 and conductive pole 2 in brace 4 upper punch swagings, thereby brace 4 is being fixedly mounted on each conductive pole 2.

Shown in Fig. 3,4, the through hole 1-1 on the utility model end cap 1 preferably has three and uniform along the center line of end cap 1.As shown in Figure 1, 2, described conductive pole 2 has three.Shown in Fig. 1,4, described through hole 1-1 forms flange 1-2 through punching press, after the through hole 1-1 on the end cap 1 adopts punching press to form flange 1-2, can make glass insulator 3 larger with the contact area of through hole 1-1, thereby makes insulation, sealing property better.

Through on probation, binding post of the present utility model not only has good sealing property and insulation property, and guarantee to compress function and work reliably, and also simple in structure, easily manufactured, production cost is low, and long service life has obtained good effect.
