External cover material for wire harness

An external cover material for a wire harness, comprising:

• a metal pipe through which a wire harness including a plurality of electrical wires can be inserted;
• and
• a separate metal partition member that is to be assembled by being inserted into the pipe;
• wherein a plurality of electrical wire insertion spaces that are partitioned by the partition member and a circumferential wall of the pipe are provided continuously in an axial direction of the pipe,
• wherein fitting depressions, into which projecting edges at an outer circumference of partition plates of the partition member are fitted, extend in the axial direction in an inner circumferential face of the pipe, and are provided in the inner circumferential face of the pipe at a constant pitch in a circumferential direction of the pipe,
• wherein the edges at the outer circumference of the partition plates are fitted into the fitting depressions at any position of the fitting depressions provided at the constant pitch, and
• wherein each of the fitting depressions comprises a depression having a trapezoidal shape in which both side faces widen in an inward radial direction of the pipe.

An external cover material for a wire harness, comprising:

• a metal pipe through which a wire harness including a plurality of electrical wires can be inserted;
• and
• a separate metal partition member that is to be assembled by being inserted into the pipe,
• wherein a plurality of electrical wire insertion spaces that are partitioned by the partition member and a circumferential wall of the pipe are provided continuously in an axial direction of the pipe, and
• wherein the pipe is drawn (swaged) throughout the length of the pipe, or at least both ends in the length direction of the pipe are partially crimped, so that edges at an outer circumference of the partition member are pressed against and fixed to an inner circumferential face of the pipe.

A method for attaching an external cover material to a wire harness, comprising:

• inserting separated electrical wires of a wire harness into spaces that are partitioned by the partition member;
• fixing the electrical wires and the partition member using a tape or a cable tie;
• inserting the partition member holding the electrical wires through the pipe;
• and
• drawing or partially crimping the pipe, thereby fixing the partition member and the pipe, and then bending the pipe according to a form in which the wire harness is to be arranged.
