Abstract
An objective is to provide a manufacturing method and a manufacturing device for a wire harness, and the wire harness and a retention component manufactured thereby, the wire harness including a wiring bundle, a retention portion configured to retain the wiring bundle, and an engagement portion to be attached to a vehicle body, the manufacturing method and the manufacturing device being capable of efficiently manufacturing the wire harness and being applicable to engagement portions having different shapes.
Claims9
A method for manufacturing a wire harness including an engagement portion to be attached to a vehicle body, a wiring bundle formed of multiple wiring members, and a retention portion configured to retain the wiring bundle,
- with usage of a metal mold having:
- a wiring bundle disposition hole in which the wiring bundle is penetratingly disposed;
- an annular retention portion-molding space arranged at an intermediate section of the wiring bundle disposition hole to surround an outer circumference of the disposed wiring bundle;
- an engagement portion-accommodating space in which an insert part having a penetration hole formed therein and which is to become the engagement portion is disposed such that the penetration hole is communicatively connected with the retention portion-molding space;
- and a resin inflow opening through which a melt resin is poured into the penetration hole of the insert part disposed in the engagement portion-accommodating space, the method comprising:
- penetratingly disposing the wiring bundle in the
- wiring bundle disposition hole of the metal mold;
- disposing the insert part in the engagement portion-accommodating space;
- pouring the melt resin through the resin inflow opening to load the melt resin to the retention portion-molding space through the penetration hole of the insert part;
- and
- solidifying the melt resin through cooling to form the wire harness, the wire harness including the wiring bundle, the retention portion, and the engagement portion formed by the insert part, the retention portion having an annular portion molded in a state of being closely adhered to a rugged outer circumferential surface of the wiring bundle in the retention portion-molding space, and a core portion molded in the penetration hole, the annular portion and the core portion being molded integrally with each other, the retention portion being joined to the insert part.
A wire harness comprising:
- a wiring bundle formed of multiple wiring members;
- a retention portion made of a resin, and including an annular portion configured to surround and retain the wiring bundle while being closely adhered to a rugged outer circumferential surface of the wiring bundle, and a core portion projecting outward from an outer circumferential surface of the annular portion, the annular portion and the core portion forming one unitary body;
- an engagement portion made of a resin, and including a shaft portion capable of being inserted into a predetermined attachment hole on a vehicle body side, an engagement attachment portion capable of being engaged with and attached to a surrounding portion of the attachment hole, and a connecting portion connected to the retention portion, the shaft portion, the engagement attachment portion, and the connecting portion forming one unitary body;
- and
- a penetration hole formed in the engagement portion so as to penetrate the engagement portion, and having the core portion disposed therein.
A retention component comprising:
- a retention portion made of a resin, and including an annular portion configured to surround and retain a wiring bundle formed of multiple wiring members while being closely adhered to a rugged outer circumferential surface of the wiring bundle, and a core portion projecting outward from an outer circumferential surface of the annular portion, the annular portion and the core portion forming one unitary body;
- an engagement portion made of a resin, and including a shaft portion capable of being inserted into a predetermined attachment hole on a vehicle body side, an engagement attachment portion capable of being engaged with and attached to a surrounding portion of the attachment hole, and a connecting portion connected to the retention portion, the shaft portion, the engagement attachment portion, and the connecting portion forming one unitary body;
- and
- a penetration hole formed in the engagement portion so as to penetrate the engagement portion, and having the core portion disposed therein.
