Cable assembly and manufacturing method thereof

A cable manufacturing method, comprising:

• providing a wire, the wire comprising a transmission wire extending along a first direction, a first metal covering layer extending along the first direction and covering the transmission wire, an inner insulating layer extending along the first direction and covering the first metal covering layer, a second metal covering layer extending along the first direction and covering the inner insulating layer, and an outer insulating layer extending along the first direction and covering the second metal covering layer, the wire comprising an axial end edge;
• cutting off the outer insulating layer and the second metal covering layer at a first position at a first distance from the axial end edge, peeling off the cut-off outer insulating layer and the second metal covering layer;
• disposing an insulating protective layer at an axial end part of the cut-off position of the first position of the second metal covering layer, covering the axial end part of the second metal covering layer with the insulating protective layer;
• forming an outer metal layer, the outer metal layer extending radially from the first metal covering layer to cover the insulating protective layer.
