Wire harness with metal pipe and cap
View Patent ↗A wire harness includes conducting paths, a metal pipe into which the conducting paths are inserted, and a conducting path protective cap which includes a through hole for the conducting paths, and an engaging part which is engaged with a terminal part of the metal pipe. The terminal part of the metal pipe has a ring-like cap engagement space formed by crushing the terminal part towards a predetermined direction from a pipe outer surface of the metal pipe. The ring-like cap engagement space includes a reduced space and an enlarged space formed due to a crushing of the terminal part. The reduced part is formed by narrowing a part of a gap between the conducting paths and the pipe inner surface due to the crushing, and the enlarged space is formed by enlarging a part of the gap in accordance with a formation of the reduced space.
1. A wire harness, comprising:
a plurality of conducting paths;
a metal pipe into which the plurality of conducting paths are inserted; and
a conducting path protective cap which includes a through hole for the plurality of conducting paths, and an engaging part which is engaged with a terminal part of the metal pipe, wherein
the terminal part of the metal pipe has a non-circular cross section,
the terminal part of the metal pipe has a ring-like cap engagement space between the plurality of conducting paths and a pipe inner surface of the metal pipe,
the ring-like cap engagement space includes a reduced space and an enlarged space, wherein the reduced part is formed by narrowing a part of a gap between the plurality of conducting paths and the pipe inner surface, and the enlarged space is formed by enlarging a part of the gap in accordance with a formation of the reduced space, and
the conducting path protective cap has a non-circular cross section being the same shape as the non-circular cross section of the terminal part of the metal pipe,
wherein a diameter of a body portion of the metal pipe other than the terminal part is sized such that a gap between the plurality of conducting paths and a pipe inner surface of the body portion of the metal pipe is smaller than a thickness of the engaging part of the conducting path protective cap.
2. The wire harness according to claim 1 , wherein
a shape of the non-circular cross section of the terminal part of the metal pipe is dependent upon the number of conducting paths of the plurality of conducting paths which are inserted in the metal pipe.
3. The wire harness according to claim 2 , wherein
the plurality of conducting paths includes two conducting paths aligned with each other, and
the non-circular cross section of the terminal part of the metal pipe is an oval shape due to the crushing of the terminal part to form a pair of reduced spaces and a pair of enlarged spaces between the two conducting paths and the pipe inner surface of the terminal part of the metal pipe.
4. The wire harness according to claim 1 , wherein
a portion of the metal pipe other than the terminal portion has a cross section other than the non-circular cross section of the terminal part.
