Seal structure for multi-core cable
A multi-core cable in which electrical wires are enveloped by a sheath, a sheath rubber plug that is fitted around the terminal of the sheath, an electrical wire rubber plug through which the electrical wires, which extend from the terminal of the sheath, individually pass, and a housing that has attachment holes into which the sheath rubber plug and the electrical wire rubber plug are respectively fitted.
1. A seal structure for a multi-core cable, the seal structure comprising:
a multi-core cable in which a plurality of electrical wires are enveloped by a sheath;
a sheath rubber plug that has an inner peripheral surface, the sheath rubber plug is fitted around a terminal of the sheath so that the inner peripheral surface of the sheath rubber plug contacts and seals against an exterior of the terminal of the sheath;
an electrical wire rubber plug through which the electrical wires individually pass has an inner peripheral surface, the electrical wire rubber plug is individually fitted around each of the electrical wires so that the inner peripheral surface of the electrical wire rubber plug contacts and seals against exteriors of the electrical wires, and the electrical wires extend from the terminal of the sheath;
a housing through which the electrical wires individually pass has attachment holes into which the sheath rubber plug and the electrical wire rubber plug are respectively fitted and sealed; and
a cap through which the electrical wires individually pass is attached to the housing.
2. The seal structure for a multi-core cable according to claim 1 , wherein the electrical wire rubber plug is constituted by a plurality of individual rubber plugs that each include a through-hole through which one of the electrical wires passes.
3. The seal structure for a multi-core cable according to claim 1 , wherein the electrical wire rubber plug is constituted by an integrated rubber plug having a single rubber plug main body provided with a plurality of through-holes through which the electrical wires individually pass.
4. The seal structure for a multi-core cable according to claim 1 , wherein the cap retains the electrical wire rubber plug.
