Waterproof connector

Abstract

A waterproof connecter is provided with a frame including a plurality of accommodating rooms, a plurality of sub-connectors accommodated in the accommodating rooms, respectively, and gaskets for sealing gaps between the sub-connectors and the accommodating rooms, respectively. A side surface of each of the sub-connectors is provided with a sealing surface which comes into close contact with each of the gaskets. Each of the gaskets is provided with engagement projections, and engagement holes which correspond to the engagement projections are provided in an inner wall of each of the accommodating rooms of the frame. By allowing the engagement projections to be engaged with the engagement holes, the gaskets are fixed to the inner walls of the accommodating rooms.

Claims

1. A waterproof connector, comprising: a frame including a plurality of accommodating rooms;a plurality of sub-connectors to be accommodated in the accommodating rooms, respectively; andgaskets for sealing gaps between the sub-connectors and the accommodating rooms,wherein the gaskets are fixed to inner walls of the accommodating rooms, and sealing surfaces are provided on outer circumferences of the sub-connectors to obtain sealability by pressing the sealing surfaces against inner circumferences of the gaskets.

2. The waterproof connector according to claim 1, wherein engagement projections are provided in either the gaskets or the inner walls of the accommodating rooms, engagement holes are provided in opposite gaskets or inner walls of the accommodating rooms, and the gaskets are fixed to the inner walls of the accommodating rooms by allowing the engagement projections to be engaged with the engagement holes.

3. The waterproof connector according to claim 1, wherein protection walls are provided in the sub-connectors for protecting the gaskets by sealing inlets of the accommodating rooms when the sub-connectors are accommodated into the accommodating rooms.

4. The waterproof connector according to claim 3, wherein locking portions are provided in the frame and the sub-connectors for locking the frame and the sub-connectors to each other when the sub-connectors are accommodated into the accommodating rooms, and the locking portion on the side of the frame projects further than an end portion of the frame, and can be bent in a direction perpendicular to a direction in which the sub-connectors are inserted into the frame.

5. The waterproof connector according to claim 4, wherein the locking portions on the side of the sub-connectors are provided on rear sides of waterproof rubber stoppers to be inserted into rear ends of terminal accommodating rooms of the sub-connectors, respectively.
