Abstract

PURPOSE:To facilitate the unit replacing works and construct units in a small size by installing a connector at the termination of a harness on an object for mounting, holding the electronic unit in a holding part formed in the connector, and thereby generating electric connections. CONSTITUTION:A bracket 16 is slid until its end face collides with a stopper part of a guide 12b furnished in a connector 12, is retained with the connector, and engaged through the action of projections furnished on both members. Then a rotation preventing boss 16b and a clip 16b on the bracket are inserted in holes 4a, 4b in a car body panel 4 so that connector mounting is accomplished. An electronic unit 17 is inserted in the connector, and a detent piece 17a capable of elastic deformation is engaged by a retaining hole 12d, and a female terminal at the termination of a harness 14 in the connector is put in electric continuity to a base board in the unit 17. This ensures easiness in the unit replacing works and allows constructing the unit 17 in a small size because of no provision of female connector therein. In the fit part 12c, another connector is engaged so that annexation can be made simply.
