The production process generally comprises two resistance wire embedding processes of front wire distribution and rear wire distribution, wherein the front wire distribution is to embed the resistance wires connected with two connecting copper column feet into a mold in advance and then to perform injection molding; the back wire laying is to cut a groove on the inner wall of the injection molded pipe fitting, press and embed a copper wire in the groove, and then press and connect two copper column feet of the resistance wire on the external connection port. The prior wire laying process has high-efficiency automatic equipment, but the equipment investment is large at one time due to the integration of a plurality of processes, the equipment reliability and the material consumption are high, and the application and popularization of the wire laying process are limited to a certain extent.

The core technical problem to be solved is to simulate manual work to wind a resistance wire on a copper column base and press the copper column base into a PE pipe fitting fixing hole. Because the internal diameter of the copper column base protective shroud of PE electric smelting pipe fitting is injectd only about 10mm, will realize simultaneously in such little space that the resistance wire catches a series of actions such as fixed, copper column base centre gripping is fixed, the resistance wire convolutes copper column base root, the copper column base is whole to be impressed in PE pipe fitting copper column base protective shroud inner joint hole, have higher realization complexity.
