Apparatus and method for cutting braid of shielded wire

A braid cutting device 7 of a shielded wire includes a die 107 located outside an exposed braid 22 of a shielded wire 15, a braid opening means (110), a circular punch which advance inside the braid, a guide member 109 for guiding the braid 22 in a direction of opening the braid 22 and guiding the inner sheath of the shielded wire inside the braid inside the punch 108. The guide member 109 can be divided into two segments. When the punch 108 is moved forward, the guide member can open outwardly and move backward by a driving means 123 and moving means 122. The braid 22 is opened by the opening means and further opened along the outer slope of the guide member 109. The braid 22 is further opened by the guide member in such a way that the guide member is opened. The inner sheath of the braid is guided along the inner slope of the guide member into the inside of the circular punch 108. The braid is cut into a prescribed length between the punch approached into the inside of the braid and the die 107 located outside the braid. In this configuration, the braid of a shielded wire can be cut automatically and effectively.
