Abstract

An electric device terminal apparatus includes: a housing having a fitting portion that can fit together with a partner member; a storage groove provided in the periphery of the fitting portion, on an end surface of the housing that faces the partner member; and a ring-shaped seal member that is provided in the storage groove and water-tightly seals a space between the end surface of the housing and the partner member. The storage groove is filled with a liquid gasket as the seal member.

First claim

The invention claimed is:

1. An electric device terminal apparatus comprising:
a housing having a fitting portion that can fit together with a connector of a wire harness, which is a partner member, and an end surface that faces a case edge of the connector of the wire harness;
a storage groove that is provided in the periphery of the fitting portion on the end surface of the housing; and
a ring-shaped seal that is provided in the storage groove and water-tightly seals a space between the end surface of the housing and the case edge of the connector of the wire harness,
wherein the seal member is a liquid gasket filled in the storage groove and configured so as to closely adhere to the case edge of the connector of the wire harness.

2. The electric device terminal apparatus according to claim 1 ,
wherein unevenness is included on the bottom surface of the storage groove.

3. The electric device terminal apparatus according to claim 2 ,
wherein a plurality of recessed streaks and protruding streaks are formed continuously as the unevenness.

4. The electric device terminal apparatus according to claim 2 ,
wherein a plurality of protrusions or a plurality of recesses are formed as the unevenness.

5. A method for manufacturing an electric device terminal apparatus, the method comprising the steps of:
providing a housing with an end surface having a fitting portion that can fit together with a connector of a wire harness, which is a partner member, and the end surface facing a case edge of the connector of the wire harness,
providing a ring-shaped storage groove is in the periphery of the fitting portion,
filling the storage groove with a liquid gasket, and
hardening a surface of the liquid gasket by irradiating the surface with ultraviolet beams to form a ring-shaped seal that water-tightly seals a space between the end surface of the housing and the case edge of the connector of the wire harness, the ring-shaped seal closely adhering to the case edge of the connector of the wire harness.
