Embodiment Construction
[0023] With regard to the above technical solutions, preferred embodiments are given and described in detail in conjunction with the drawings. in:
[0024] Composite melt, see figure 1 and figure 2 , including a conductive melt 2, the melt 2 is a long sheet structure, at least one narrow diameter 3 is arranged on the melt 2, and a layer of insulation covering the narrow diameter is provided at the outer peripheral surface of the narrow diameter 3 Protective layer 4, the two ends of the melt are located outside the insulating protective layer. When there are multiple narrow diameters on the melt, if the distance between each narrow diameter is relatively wide, an insulating protective layer can be provided at each narrow diameter; An insulating protective layer is provided; or a plurality of slits are grouped, and an insulating protective layer is provided at each group of slits.
[0025] In order to better reduce the volume of the composite melt, it is optimal that the in...
