Embodiment
In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1-Fig. 3, the utility model provides coaxial vertical connects around built-up coil around Internal and external cycle, comprises identical first the connecting coiling 10 and second and connect coiling 11 of shape.As shown in Figure 1, first company's coiling 10 comprises coaxial great circle portion 101 and ringlet portion 102.As shown in Figure 2, second company's coiling 11 comprises coaxial great circle portion 111 and ringlet portion 112.After the ringlet portion 102 of first company's coiling 10 and the second mutual spiral of ringlet portion 112 that connects coiling 11 move into, as shown in Figure 3, the first ringlet portion 102 that connects coiling 10 is contained in second and connects in the great circle portion 111 of coiling 11, and the second ringlet portion 112 that connects coiling 11 is contained in first and connects in the great circle portion 101 of coiling 10.
Compared to the situation of prior art, the utility model provides coaxial vertical connects around built-up coil around Internal and external cycle, used two even coilings all have the large ringlet portion of coaxial continuous coiling, the Internal and external cycle length of built-up coil is identical, inner-outer coil D.C. resistance equates, heating balance.In the time producing, the coil of two combination use is identical, and two coils can exchange, and only needs a set of winding mould, has saved a set of frock clamp.
In the present embodiment, the great circle portion 101 of above-mentioned first company's coiling 10 is identical with the number of turn of ringlet portion 102, and the second great circle portion 111 of coiling 11 of company is all identical with the number of turn of ringlet portion 112.Certainly; identical structures because first company's coiling 10 and second connects coiling 11; carrying out coiling with a set of frock clamp makes; therefore; the number of turn of ringlet portion also can be slightly less than the number of turn of great circle portion; as long as ringlet portion can be contained in great circle portion, guarantee that first connects the D.C. resistance that coiling and second connects coiling and equate and send out structure thermally equilibrated, all fall into protection range of the present utility model.
