Abstract

The waterproof connector in which an O-ring is attached to a front end of a connector housing by a supporting ring, and the O-ring is prevented from falling from a connector housing even the supporting ring is in a preliminarily locking state. The waterproof connector according to the present invention comprises: a connector housing with projections at an end thereof; a plurality of terminal accommodating cavities with resilient locking pieces in the connector housing for accommodating terminals which are inserted in the terminal accommodating cavities; a packing attached to the end portion of the connector housing; and a packing support with spacers projecting on a wall thereof which opposes the connector housing, the packing support further having accommodating concave portions for accommodating the projections of the connector housing, wherein the spacers of the packing support allow the resilient locking pieces of the terminal accommodating cavities to resiliently deflect in a preliminarily locked state and prevent the resilient locking pieces from resiliently deflecting in a fully locked state, and the packing support which is situated apart from the packing in the preliminarily locked state, becomes in contact with the packing in the fully locked state, and the accommodating concave portions of the packing support receives the projections therein.

Claims

1. A waterproof connector comprising:

a connector housing with projections at an end thereof;

a plurality of terminal accommodating cavities with resilient locking pieces in the connector housing for accommodating terminals which are inserted in the terminal accommodating cavities;

a packing attached to the end portion of the connector housing; and

a packing support with spacers projecting on a wall thereof which opposes the connector housing, said packing support further having accommodating concave portions for accommodating the projections of the connector housing,

wherein the spacers of the packing support allow the resilient locking pieces of the terminal accommodating cavities to resiliently deflect in a preliminarily locked state and prevent the resilient locking pieces from resiliently deflecting in a fully locked state, and the packing support which is situated apart from the packing in the preliminarily locked state, becomes in contact with the packing in the fully locked state, and the accommodating concave portions of the packing support receives the projections therein.

2. A waterproof connector as claimed in claim 1, wherein said projections of the connector housing are formed such that substantially round end portion of the connector housing are divided with regular intervals in the circumferential direction of the end portion, and the accommodating concave portions include slits which pass through the packing support for accommodating the projections.
