In order to reduce cable transmission loss and improve cable phase stability, these cables widely use copper tape wrapped outer conductor. For this type of cable, the standing wave coefficient in its entire frequency band is an important indicator of cable quality, which mainly depends on the manufacturing process of copper tape wrapped outer conductor.

The utility model utilizes that when the copper flat strip is inserted into the body, the copper flat strip extends into the wrapping hole along the wrapping seam and can be connected to the cable core without bending. The copper flat strip entering the body is limited by the cylindrical body, and the copper flat strip is attached to the annular cavity between the inner wall of the wrapping hole and the side of the cable core, which plays the role of limiting the copper flat strip.
