Step b, tightly sleeving a metal ring 20 at the exposed section 16 of the shielding layer formed in step a by a collar process, as shown in the middle drawing in fig. 1;
Step c, the epidermis at the mark 18 is stripped, at this time, the shielding wires of the shielding layer exposed section 16 begin to be scattered 19, as in the lowest figure of fig. 1, but as the shielding layer exposed section 16 in the previous step is tightly sleeved with a metal ring 20, the scattering 19 of the shielding layer exposed section 16 is not transferred to the part without peeling, thereby solving the problems.
