Finally, the welding position of the feed conductor is exposed out of the oscillator body and is directly welded with the cable, the cable is not positioned, the welding spot is not protected, and hidden dangers such as short circuit and fracture exist, so that the electrical performance is influenced, and the problem of cost increase caused by secondary operation can be caused.
