When the aforementioned core wire is connected to the metal terminal 221, the transmission line can be carried on the connecting band 224, but the aforementioned transmission line and the connecting band 224 The contact area between is provided with the insulating layer. Or, when the transmission line is used as a ground wire, in addition to the welding place with the ground terminal 222, the area adjacent to the welding place can also be carried on the connecting strap 224. In this way, due to the bearing function of the connecting strap 224, not only can the transmission line 24 be stably connected to the metal terminal 221 and/or the ground terminal 222, but also the wire adjacent to the welding point can be prevented from being excessively bent and broken.

Furthermore, in order to facilitate the assembly of the metal terminals 221 and the ground terminal 222 into the insulating body 21, the connecting terminal set 22 further includes a terminal base 225, wherein the terminal base 225 can be made of insulating material, and the metal terminals 221. Local areas of the grounding terminals 222 and the conductive plastic part 223 can be respectively located in the terminal base 225, so that the metal terminal 221, the grounding terminal 222 and the conductive plastic part 223 can be moved at the same time through the terminal base 225.
