Connector formation structure, electronic control apparatus and production method for connector formation structure
Airtightness of a connector molding is improved. There is provided a connector molding in which a conductor and a fixing member are integrally molded with a molded body including a connector portion. The conductor is fixed to the fixing member, and is integrally molded with the molded body in a state in which an external connection end portion protrudes into a space within the connector portion. A part of the fixing member is exposed to the space within the connector portion and the remaining portion is covered by the molded body, or the entire fixing member is covered by the molded body.
1. A connector molding comprising:
a conductor that includes an external connection end portion;
a fixing member that fixes the conductor; and
a molded body that includes a connector portion having an internal space through which the external connection end portion is exposed, the conductor and the fixing member being integrally molded with the molded body, wherein
the conductor is fixed to the fixing member, and is integrally molded with the molded body in a state in which the external connection end portion protrudes into the space within the connector portion,
(i) a part of the fixing member is exposed to the space within the connector portion, and a remaining portion is covered by the molded body, or
(ii) the entire fixing member is not exposed from an outer surface of the molded body, and
the molded body has a holding groove into which a conductor is fitted, a locking part which is provided along the holding groove and fixes the conductor fitted into the holding groove, and an opening which is formed astride a plurality of holding grooves adjacent to each other, the opening being filled with a mold resin in the molded body.
2. The connector molding according to claim 1 ,
wherein the fixing member includes a fixing portion that fixes the conductor, and the fixing portion includes an opening or an engagement portion.
3. The connector molding according to claim 1 ,
wherein the fixing member is exposed to the space within the connector portion at a plurality of locations.
4. The connector molding according to claim 1 ,
wherein the conductor includes a leading portion connected to the external connection end portion, and the leading portion includes a folded portion, and
the fixing member includes a first fixing portion that fixes one end portion side of the folded portion and a second fixing portion that fixes the other end portion side of the folded portion.
5. An electronic control device comprising:
the connector molding according to claim 1 ; and
a housing that houses an electronic component,
wherein the connector molding includes a housing portion that houses an electronic component, an internal connection end portion of the conductor is connected to the electronic component within the housing portion, and the housing portion and the housing are assembled while being sealed externally.
6. The connector molding according to claim 1 ,
wherein the molded body includes a housing portion that houses an electronic component, and
the conductor includes an internal connection end portion exposed within the housing portion at the other end of the external connection end portion.
7. The connector molding according to claim 6 ,
wherein the connector molding is a cover attached to a housing of an electronic control device so as to be sealed from the outside.
8. A method for manufacturing a connector molding, comprising:
fixing a conductor including an external connection end portion by a fixing member; and
supporting a part of the fixing member by a support portion of a mold, and forming a molded body including a connector portion having an internal space through which the external connection end portion is exposed through insert-molding using the conductor and the fixing member as insert members, wherein
the molding is performed such that the part of the fixing member supported by the mold is positioned at an interface with the space of the connector portion, and
the bolded body has a holding groove into which a conductor is filled, a locking part which is provided along the holding groove and fixes the conductor fitted into the holding groove, and an opening which is formed astride a plurality of holding grooves adjacent to each other, the opening being filled with a mold resin in the molded body.
9. The method for manufacturing a connector molding according to claim 8 ,
wherein the insert-molding is performed in a state in which the conductor is fixed by an opening or an engagement portion formed at the fixing member.
