Electric supply apparatus
The present invention is to provide an electric supply apparatus having a small size protector and being long lifetime. The electric supply apparatus having a wiring harness includes a protector; an annular wall disposed inside the protector, the wiring harness being bent freely along the annular wall; a leaf spring arranged around the annular wall, the leaf spring being fixed to the annular wall at a base end; and a spring holder disposed at a front end of the leaf spring for holding the wiring harness at a loop forming portion thereof. The spring holder is bent at a middle portion thereof with an angle in a direction of tangent of the annular wall. The spring holder fastens protective tubes of the wiring harness. The spring holder fastens end portions of a corrugated tube and a net tube which form the protective tube, and the net tube is disposed along the leaf spring.
1. An electric supply apparatus having a wiring harness comprising:
a protector;
an annular wall disposed inside the protector, the wiring harness being bent freely along said annular wall;
a leaf spring arranged around the annular wall, said leaf spring being fixed to the annular wall at a base end; and
a spring holder disposed at a front end of the leaf spring for holding the wiring harness at a loop forming portion thereof, and fastening together two protective tubes of the wiring harness.
2. The electric supply apparatus as claimed in claim l,wherein said spring holder is bent at a middle portion thereof with an angle in a direction of tangent of the annular wall.
3. The electric supply apparatus as claimed in claim 2 , wherein said spring holder has a leaf spring holder at the bent side thereof.
4. The electric supply apparatus as claimed in claim 1 , wherein said spring holder has a rib at an inner wall of a middle portion thereof and said rib extends inwardly higher than an inner face of an end portion of the protective tube.
5. An electric supply apparatus having a wiring harness comprising:
a protector;
an annular wall disposed inside the protector, the wiring harness being bent freely along said annular wall;
a leaf spring arranged around the annular wall, said leaf spring being fixed to the annular wall at a base end; and
a spring holder disposed at a front end of the leaf spring for holding the wiring harness at a loop forming portion thereof, and fastening protective tubes of the wiring harness; wherein said spring holder fastens end portions of a corrugated tube and a net tube which form the protective tube, and the net tube is disposed along the leaf spring.
6. The electric supply apparatus as claimed in claim 5 , wherein said spring holder includes a first holder having ribs for engaging with grooves of the corrugated tube and a second holder for holding an insertion member attached to the net tube.
7. An electric supply apparatus having a wiring harness comprising:
a protector;
an annular wall disposed inside the protector, the wiring harness being bent freely along said annular wall;
