In order to improve the anti-jamming performance, the general cable will cover the inner core wire with a shielding layer made of woven material, which can reduce the shielding effect of radiation, signal leakage or attenuation, and make the wire have a higher transmission rate. . Therefore, generally, during the processing of the end of the cable, all the portions of the shielding layer exposed outside the end are not cut off, but the exposed portion is retained and trimmed and then replaced with the metal casing of the connector. The parts are joined by welding or riveting, so that the finished product has better anti-EMI performance, higher transmission rate and the like.

However, for the exposed portion of the above shielding layer to be trimmed, the conventional processing method is mostly manual, especially in the trimming operation, the coating layer outside the cable is first peeled off for a short period, so that after the shielding layer is exposed, Then, the exposed shielding layer is folded in a diffused manner to wrap the edge of the cladding layer, and finally passed through a process such as wrapping copper foil for subsequent processing. In the above-mentioned manual folding of the exposed shielding layer in a diffused manner to wrap the edge of the coating layer, the processing is time-consuming, laborious and inconvenient, and the artificial shielding cannot ensure that the braided shielding layer is folded back. Uniformity also easily affects the shielding effect of the final product.
