Abstract
Continuous annular resin bands surrounding electrical contact portions of respective terminals are disposed without gaps between the electrical contact portions of respective terminals and resin members that fixedly hold the terminals; there are formed gaps among the adjoining resin bands. Gaps are formed among a bundle of terminals having annular resin bands and resin members surrounding the bundle. A partial adhesion is formed at the interface between the terminals and the resin by a low cost manufacturing method, whereby a molding with high air-tightness between the interior and exterior thereof and high reliability is realized.
Claims18
A composite molding characterized in that resin bands surrounding the circumference of terminal components for electrically connecting with an exterior are formed between electrical contact portions of the terminal components and resin for fixedly holding the terminal components, and gaps are formed among the adjoining resin bands.
A composite molding characterized in that a circumference of each of terminal components is covered with continuous annular resin band between electrical contact portions of the terminal components and resin for fixedly holding the terminal components, and there are gaps among adjoining resin bands, the composite molding being insert-molded using the terminal components as an insert.
A composite molding comprising:
- electrical contact portions of electrical connecting terminals;
- resin member for fixing the electrical connection terminals;
- resin bands for pre-molding circumference of the terminals;
- and gaps formed among the resin band and another resin band;
- wherein the resin for pre-molding contains no filler molds the pre-molded terminals as an insert, the resin for the pre-molding and the resin for molding the insert being the same and the resin for molding containing filler.
