Wire harness and cable waterproof structure
A wire harness is provided with a cable including wires coated with a sheath, a rubber stopper that covers an end of the sheath together with a portion in a longitudinal direction of the wires, and a cover made of a harder material than the rubber stopper and accommodating the rubber stopper. The rubber stopper integrally has a sheath sealing portion having an inner peripheral surface that comes into contact with an outer peripheral surface of the sheath, and a wire sealing portion including plural insertion holes to which the wires are inserted. The cover integrally has a sheath holding portion that crimps and holds an uncovered portion of the sheath that is not covered by the rubber stopper, and a rubber stopper holding portion that crimps and holds the rubber stopper.
1. A wire harness, comprising:
a cable comprising wires coated with a sheath;
a rubber stopper that covers an end of the sheath together with a portion in a longitudinal direction of the wires; and
a cover comprising a harder material than the rubber stopper and accommodating the rubber stopper,
wherein the rubber stopper integrally comprises a sheath sealing portion having an inner peripheral surface that comes into contact with an outer peripheral surface of the sheath, and a wire sealing portion including plural insertion holes to which the wires are inserted,
wherein the cover comprises a pair of cover members, and integrally comprises a sheath holding portion that crimps and holds a portion of the sheath that is not covered by the rubber stopper, and a rubber stopper holding portion that crimps and holds the rubber stopper,
wherein an outer peripheral surface of the rubber stopper is formed with plural ribs that contact the pair of cover members,
wherein the wires comprise a first group of wires derived from the cover toward a first direction, and a second group of wires derived from the cover toward a second direction different from the first direction, and wherein the rubber stopper includes the insertion holes to which the first group of wires and the second group of wires are inserted respectively, and
wherein the cover further comprises a wire holding portion that holds the wires derived from the rubber stopper along an alignment direction of the sheath holding portion and the rubber stopper holding portion, a first wire holding portion that accommodates the first group of wires, extends in the first direction, and derives the first group of wires toward the first direction, and a second wire holding portion that accommodates the second group of wires, extends in the second direction, and derives the second group of wires toward the second direction.
2. The wire harness according to claim 1 , wherein the cover crimps the sheath and the rubber stopper by pinching the sheath and the rubber stopper between the pair of cover members.
3. The wire harness according to claim 1 , wherein a crimping amount of the sheath in the sheath holding portion by the cover is greater than a crimping amount of the sheath sealing portion in the rubber stopper holding portion by the cover.
4. The wire harness according to claim 1 , wherein a rubber stopper contact length of the rubber stopper holding portion is longer than a sheath contact length of the sheath holding portion.
