Abstract
An electronic circuit device comprises: a printed circuit board mounted with electronic components; a resin-molded portion formed of resin so disposed that the electronic components are covered therewith; a convex connector that has metal terminals for connection and is exposed from the resin-molded portion; and a sealing member wrapped around the resin-molded portion.
Claims18
An electronic circuit device comprising:
- a circuit board mounting an electronic component;
- a resin-molded portion formed of resin for covering the electronic component;
- a convex connector that has a metal terminal for connection and is exposed from the resin-molded portion;
- and a sealing member wrapped around the resin-molded portion.

A connecting structure for electronic circuit device comprising:
- an electronic circuit device, which comprises a circuit board mounted with electronic components, a resin-molded portion formed of resin so disposed that the electronic components are covered therewith, a convex connector that has metal terminals for connection and is exposed from the resin-molded portion, and a sealing member wrapped around the resin-molded portion;
- and a concave connector having a housing, a concave portion formed in the housing, and metal terminals for connection formed on the bottom of the concave portion, whereby when the convex connector is inserted into the concave portion of the concave connector so that the metal terminals for connection of the convex connector are brought into contact with the metal terminals for connection of the concave connector, the sealing member is pressed against the wall portion of the concave portion of the housing and the contact area between the two of metal terminals for connection are sealed from the outside.
A production method for an electronic circuit device comprising:
- a circuit board mounted with electronic components;
- a resin-molded portion formed of resin so constructed that the electronic components are covered therewith;
- a convex connector that has metal terminals for connection and is exposed from the resin-molded portion;
- and a sealing member wrapped around the resin-molded portion, the production method comprising the steps of:
- preparing a circuit board that has a convex connector at an end thereof and is mounted on the surface thereof with electronic components;
- preparing two molds so as to form a cavity comprising a first portion corresponding to the outside shape of the resin-molded portion and a second portion in which the convex connector is disposed;
- sandwiching the circuit board between the two molds;
- and
- injecting resin into the cavity through a resin injection portion formed between the two molds.
