Abstract

A jig for loosening electric wires of a wire harness passed through a grommet is disclosed. The jig includes a fixing-side clamping portion for clamping the one end of a wire harness, a guide rail extending in a longitudinal direction of the wire harness, a bearing slidably engaged with the guide rail; a lock portion for locking said bearing to the guide rail, a circular rotating member, supported by said bearing, for rotating the wire harness in a circumferential direction of the wire harness; and a movable-side clamping portion, integrally attached to the rotating member, for clamping the other end of the wire harness. The rotating member may have a spiral cam groove, and the bearing may have an engagement protrusion to be engaged with the cam groove so that when the one clamping portion is inverted, the rotating member can move in its longitudinal direction. The one clamping portion may include a rachet mechanism. Further, the one clamping portion may be shifted in a direction of compressing the wire harness by a motor.

Claims

1. A wire-harness loosening jig comprising:

a fixing side clamping portion for clamping one end of a wire harness;

a guide rail extending in a longitudinal direction of said wire harness;

a bearing slidably engaged with said guide rail;

a lock portion for locking said bearing to said guide rail;

a circular rotating member, rotatable over 180°

, supported by said bearing, for rotating said wire harness in a peripheral direction of said wire harness;

a movable-side clamping portion, integrally attached to said rotating member, for clamping the other end of said wire harness; and

said rotating member including a rachet gear and a pressing protrusion, and said bearing including a switch portion for engaging an engagement piece with said rachet gear, said switching portion being changeable by said pressing protrusion so that said rachet gear can operate in a direction of twisting said wire harness.

2. A wire harness loosing jig according to claim 1, wherein said rotating member has a spiral cam groove;

and said bearing has an engagement protrusion to be engaged with the cam groove so that when the one clamping portion is inverted, the rotating member can move in the longitudinal direction of the wire harness.
