Connector, method of manufacturing connector, and wire harness
A connector includes terminals connected to metal conductors of insulated wires each formed by covering the metal conductor with an insulation, a resin case member including a housing space for housing the terminals and an end opening that opens at one end, a resin lid member fitted to the end opening of the case member, and a molded resin portion formed by molding so as to cover at least the end opening of the case member fitted with the lid member. The case member includes first grooves that have a semicircular cross section and are formed on an inner surface facing the lid member, and the lid member includes second grooves that have a semicircular cross section and form, together with the first grooves, wire insertion holes for inserting the insulated wires.
1. A connector, comprising:
terminals connected to metal conductors of insulated wires, each of the insulated wires having an insulation covering the metal conductor;
a case member comprising a housing space for housing the terminals and an end opening that opens at one end;
a lid member fitted to the end opening of the case member; and
a molded resin portion formed by molding so as to cover at least the end opening of the case member fitted with the lid member,
wherein the case member comprises first grooves that are formed on an inner surface facing the lid member,
wherein the lid member comprises second grooves that form, together with the first grooves, wire insertion holes for inserting the insulated wires,
wherein the lid member is housed in the case member,
wherein the insulated wires are sandwiched between the lid member and the inner surface of the case member,
wherein the case member and the lid member are formed of a harder material than the insulation of each insulated wire,
wherein the lid member comprises a cover portion covering the end opening of the case member except the wire insertion holes and protruding portions protruding from the cover portion toward the housing space of the case member,
wherein the insulated wires are sandwiched between the protruding portions and an inner surface of the case member,
wherein the case member is configured that locking protrusions for locking the terminals are provided on extending portions extending toward the end opening from a bottom located opposite to the end opening, and
wherein the protruding portions of the lid member prevent the extending portion from being deformed in a direction in which the locked state of the terminals by the locking protrusions is released.
2. The connector according to claim 1 , wherein the insulated wires are pressed by the lid member and are deformed such that diameters inside the wire insertion holes are reduced by not less than 0.05 mm and not more than 0.15 mm.
3. A connector, comprising:
terminals connected to metal conductors of insulated wires, each of the insulated wires having an insulation covering the metal conductor;

a molded resin portion formed by molding so as to cover at least the end opening of the case member fitted with the lid member,
wherein the case member comprises first grooves that are formed on an inner surface facing the lid member,
wherein the lid member comprises second grooves that form, together with the first grooves, wire insertion holes for inserting the insulated wires,
wherein the lid member is housed in the case member,
wherein the insulated wires are sandwiched between the lid member and the inner surface of the case member,
wherein the case member and the lid member are formed of a harder material than the insulation of each insulated wire,
wherein the insulated wires are pressed by the lid member and are deformed such that diameters inside the wire insertion holes are reduced by not less than 0.05 mm and not more than 0.15 mm.
4. A wire harness, comprising:

a molded resin portion formed by molding so as to cover at least the end opening of the case member fitted with the lid member,
wherein the case member comprises first grooves that are formed on an inner surface facing the lid member,
wherein the lid member comprises second grooves that form, together with the first grooves, wire insertion holes for inserting the insulated wires,
wherein the lid member is housed in the case member,
wherein the insulated wires are sandwiched between the lid member and the inner surface of the case member,
wherein the case member and the lid member are formed of a harder material than the insulation, and
wherein the insulated wires are pressed by the lid member and are deformed such that diameters inside the wire insertion holes are reduced by not less than 0.05 mm and not more than 0.15 mm.
5. The wire harness according to claim 4 , wherein the lid member comprises a cover portion covering the end opening of the case member except the wire insertion holes and protruding portions protruding from the cover portion toward the housing space of the case member, and
wherein the insulated wires are sandwiched between the protruding portions and an inner surface of the case member.
6. The wire harness according to claim 5 , wherein the case member is configured that locking protrusions for locking the terminals are provided on extending portions extending toward the end opening from a bottom located opposite to the end opening, and
wherein the protruding portions of the lid member prevent the extending portion from being deformed in a direction in which the locked state of the terminals by the locking protrusions is released.
