Wiring harness slack absorbing device
View Patent ↗There is provided a wiring harness slack absorbing device ( 10 ) being able to receive a folded part ( 51 ) of a wiring harness ( 25 ) without protrusion on a case body ( 31 ), so that a slim case is used for the device ( 10 ). The device ( 10 ) includes the case ( 30 ) for receiving the wiring harness ( 25 ) having an inlet 34 and an outlet ( 35 ) for the wiring harness ( 25 ), an urging member ( 23 ) for pulling the wiring harness ( 25 ) into the case ( 30 ), and a harness roller ( 15 ) moving reciprocally under an urging force of the urging member ( 23 ). The inlet 34 is disposed perpendicular to the outlet ( 35 ). The space for receiving folded part ( 20 ) is provided between the case ( 30 ) and the urging member ( 23 ). The folded part ( 51 ) of the wiring harness ( 25 ) is led through the inlet and received in the space for receiving folded part ( 20 ). A center axis of the urging member ( 23 ) is displaced from a center plane of the harness roller ( 15 ) in a direction of thickness of the case ( 30 ) so as to provide the space for receiving folded part ( 20 ).
1. A wiring harness slack absorbing device comprising:
a case having a base wall, front wall, rear wall, pair of side walls and a cover for receiving a wiring harness having an inlet formed in a side wall adjacent the rear wall, and an outlet formed in the rear wall for the wiring harness, said inlet being perpendicular to the outlet;
an urging member for urging the wiring harness toward an inside of the case; and
a harness roller around which the wiring harness is rolled and turned in a U-shape, said harness roller reciprocally moving under acting force of the urging member,
wherein a space for receiving a folded part of the wiring harness formed by forming an overlap and then bending the wiring harness 90 degrees, is provided between the base wall of the case and the urging member, and
wherein the folded part of the wiring harness is led into the case through the inlet and received in the space, such that the wiring harness is led inside the case, rolled around the roller and turned in the U-shape, and led out through the outlet.
2. The wiring harness slack absorbing device as claimed in claim 1 ,
wherein a center axis of the urging member is displaced from a center plane of said harness roller in a direction of thickness of the device for providing a large said space for receiving the folded part of the wiring harness.
