Abstract
A housing (10) is insert-molded around a core (30) holding terminal fittings (20). The core (30) is provided with a holdable portion (36) at a position exposed to outside through an opening (13) formed in the housing (10) and held in a molding die (50). Thus, the core (30) is prevented from displacements from its a proper position upon being subjected to an injection pressure of a resin. Further, the holdable portion (36) is located in a sealed area of a connector fitting portion (11) defined between the connector fitting portion (11) and a mating female connector (40), the entrance of water through the opening (13) can be prevented.
Claims10
An insert-molded connector formed by insert-molding a housing (10) at least partly covering a core (30) holding at least one terminal fitting (20) as a core assembly, the core (30) comprises a holdable portion (36;
- 60) to be held by a molding die (50) at a position at least partly exposed from the housing (10).
A method of molding an insert-molded connector, comprising the following steps:
- providing a core (30) holding at least one terminal fitting (20) as a core assembly;
- arranging a molding die (50) substantially around the core (30) in such a way that a holdable portion (36;
- 60) of the core (30) is held by the molding die (50), and
- molding a housing (10) at least partly covering the core (30) within the molding die (50).
The method of claim. 7, wherein the housing (10) and the core (30) are molded of synthetic resin materials having different colors.
