Patent ID: 8118583

Claim:
A molding construction for a resin-molded product, comprising: first and second molding dies openable and closable relative to each other along a moving direction, the first molding die having a surface facing the second molding die and a stepped recess in the surface of the first molding die, the stepped recess having a first recessed surface aligned substantially normal to the moving direction and facing the second molding die and a second recessed surface angularly aligned to the first recessed surface; an electrical connector defining an insert disposed in the first molding die, the electrical connector including a housing made of synthetic resin, the housing having a main body with a block-shaped portion having terminal insertion holes, terminals mounted in the terminal insertion holes and projecting rearward of the block-shaped portion, the housing further having two side walls projecting back from the block-shaped portion and a base wall projecting back from the block-shaped portion and joining the side walls so that a space is defined by the base wall and the side walls rearward of the block shaped portion, portions of the terminals projecting rearward of the block-shaped portion being in the space, the base wall having an inner surface facing into the space and held in close contact with the first recessed surface of the recess, the base wall further having an end surface facing away from the block shaped portion, the end surface of the base wall being held in close contact with the second recessed surface of the recess, the housing further comprising a holder having cavities aligned with terminals of the main body, intermediate terminals accommodated in the cavities and connected with the terminals in the main body; the second molding die having a surface facing a surface of the base wall of the insert while being spaced apart therefrom for defining a filling space upon closing the molding dies, a resin flow path into the filling space having an entry at a side where the recess is located, and a cross-sectional dimension of the filling space adjacent the base wall and measured perpendicular to the first recessed surface of the recess being reduced gradually along the resin flow path from a location aligned with the first recessed surface to a location along the flow path spaced from recess; a slide die movable substantially parallel to the first recessed surface of the recess in the first die and engaging the housing for urging the end surface of the base wall tightly against the second recessed surface of the recess; wherein the gradually reduced cross-sectional dimension of the filling space along the flow path causes the molten resin to urge the base wall tightly against the first surface of the recess for preventing the molten resin from flowing into the space and adjacent to the terminals.
