Embodiment Construction

[0046] Specific embodiments according to the present invention will be described below with reference to the accompanying drawings.

[0047] figure 1 (a) to image 3 (i) is a cross-sectional view for explaining steps of a method for peeling off a metal foil of a shielded electric wire according to an embodiment of the present invention. Figure 4 is a perspective view showing the structure of a shielded electric wire as an example of an operation target.

[0048] Such as Figure 4As shown, the shielded electric wire W to be handled has a structure including a core Wa formed of a wire made of soft copper, a shielding metal foil (aluminum foil or copper foil) Wb surrounding the outer periphery of the core Wa, surrounding the metal foil A shielding braid Wc at the periphery of Wb, and a sheath Wd surrounding the periphery of the braid Wc. The metal foil Wb is wound helically around the outer periphery of the core Wa while partially overlapping adjacent members. In this embod...

Abstract

When a shielded wire (W) is positioned in the insertion jig, a portion where a metal foil (Wb) is exposed at an end of the shielded wire (W) is inserted into a wire insertion hole (11) of the stripping jig through a center hole (21) of the insertion jig (20) located in front of the stripping jig. Air is blown toward an end portion of the shielded wire through an opening on the other end surface side of the peeling jig, and causes the metal foil to expand while being separated from the wire core. A cut (Wb2) is formed from a side surface in a metal foil (Wbl) expanded by blowing air in a predetermined gap (N) between one end surface (12) of the peeling jig and an end surface (24) of the insertion jig, and the metal foil starts to be cut at the cut.

Description

technical field [0001] The present invention relates to a method and apparatus for stripping metal foil from shielded electric wires. Background technique [0002] Among the types of shielded electric wires, there is a structure in which metal foil such as aluminum foil is wound around the outer circumference of a wire core (for example, "wire made of annealed copper") as a shielding material, and the outer circumference of the metal foil is covered with a sheath. set. There is also a structure in which a braid is inserted between the metal foil and the sheath. When this type of shielded electric wire is subjected to terminal processing (for example, when a connector is attached), the sheath needs to be removed. When a braid is present, the braid needs to be folded back over the jacket and the exposed foil stripped from the core. However, in shielded electric wires such as electric wires for Ethernet (registered trademark), it is difficult to peel off the reduced-diameter...
