Wiring member and method for manufacturing wiring member
An object of the present disclosure is to provide a technique for easily suppressing the intrusion of a resin into a cavity. A wiring member includes: a connector housing provided with a cavity; an electric wire in which one end portion is housed in the cavity and the other end portion extends outward from an opening portion of the cavity; a sealing component that is attached to the connector housing or the electric wire to at least partially close off a gap between the connector housing and the electric wire in the opening portion of the cavity; a resin molded part that covers a portion extending from a rear end portion of the connector housing to a position of an intermediate portion of the electric wire on the other end portion side relative to a portion provided with the sealing component.
1 . A wiring member comprising:
a connector housing provided with a cavity;
an electric wire in which one end portion is housed in the cavity and the other end portion extends outward from an opening portion of the cavity;
a sealing component that is attached to the connector housing or the electric wire to at least partially close off a gap between the connector housing and the electric wire in the opening portion of the cavity, wherein the sealing component includes a semi-tubular first member that covers the electric wire from one side and a semi-tubular second member that covers the electric wire from another side; and
a resin molded part that covers a portion extending from a rear end portion of the connector housing to a position of an intermediate portion of the electric wire on the other end portion side relative to a portion provided with the sealing component; and
wherein the sealing component includes an insertion part provided with a hole in a plate-like part through which the electric wire is passed,
the hole is formed to be smaller than the cavity, and
the plate-like part is formed to be larger than the cavity and positioned on the other end portion side of the electric wire relative to the opening portion of the cavity.
2 . The wiring member according to claim 1 ,
wherein a gate mark is left on an outer surface of the resin molded part, the gate mark being a mark of a gate that is provided in a metal mold for pouring a molten resin into the metal mold at a time of molding of the resin molded part, and
the gate mark is positioned on the other end portion side of the electric wire relative to the sealing component.
3 . The wiring member according to claim 1 ,
wherein a gate mark is left on an outer surface of the resin molded part, the gate mark being a mark of a gate that is provided in a metal mold for pouring a molten resin into the metal mold at a time of molding of the resin molded part, and
the gate mark is positioned on the other end portion side of the electric wire relative to the sealing component.
4 . The wiring member according to claim 3 ,
wherein a surface of the sealing component facing a front end portion of the connector housing is in contact with the connector housing.
5 . A manufacturing method of a wiring member, comprising:
a preparing step of, for a connector-equipped electric wire in which an end portion of an electric wire is housed in a cavity of a connector housing, providing the connector housing or the electric wire with a sealing component that at least partially closes off a gap between the connector housing and the electric wire in an opening portion of the cavity, and placing the connector-equipped electric wire and the sealing component in a metal mold; and
a molding step of pouring a molten resin into the metal mold after the preparation step wherein, in the molding step, an outer circumferential portion of the sealing component is partially pressed by the metal mold.
