Abstract
Firstly, the tip portion of the braided sheath S3 exposed at the terminal thereof by stripping the outer jacket off S4 is widened into the shape of a funnel. Then the internal blades 9 disposed in the shape of a two-piece cylinder hold the periphery of the portion of the braided sheath not to be removed, and the cylindrical external blade 16 is inserted between the braided sheath S3 and the internal insulating material S2 to catch and cut the braided sheath S3 by means of the external blade 16 and the internal blades 16a and 9a.
Claims7
An apparatus for cutting a braided sheath of a shielding wire, said wire having a longitudinal axis, said apparatus comprising;
- a stripping mechanism that strips an outer jacket of a shielding wire;
- a clamping mechanism that registers and clamps the shielding wire to resist axial movement thereof;
- a widening mechanism that widens a tip of the braided sheath;
- and
- a cutting mechanism having a first blade element in the shape of a multi-piece cylinder and a second blade element supported by a slider and opposed to said first blade element, wherein said first blade element is provided around a periphery of a portion of the braided sheath to be retained, said second blade element is insertable between the braided sheath and an internal insulating material of the shielding wire, and said second blade element and said first blade element cooperate to cut a portion of said braided sheath isolated from said internal insulating material, and wherein the multi-piece cylinder constitutes the clamping mechanism.
A method for cutting a braided sheath of a shielding wire having a longitudinal axis, comprising:
- stripping an outer jacket of the shielding wire to expose the braided sheath;
- widening a tip of the exposed braided sheath into a funnel shape;
- clamping a periphery of a portion of the braided sheath not to be removed with a first blade element in the shape of a multi-piece cylinder to resist axial movement of the shielding wire;
- providing a cylindrical second blade element opposed to the first blade element along a longitudinal direction of the shielding wire;
- inserting said second blade element from a terminal side of the wire between the braided sheath and an internal insulating material of the shielding wire;
- and
- cutting a portion of the braided sheath isolated from the internal insulating material with said second blade element and said first blade element.
