Abstract

There is provided a waterproof electrical connector including a male connector housing and a female connector housing for connection with the male connector housing. A hood portion is provided on one of the male connector housing and the female connector housing. A packing within the hood portion provides a waterproof seal for the connector. A packing press ring presses against and retains the packing within the hood portion. Vent hole portions are provided on a portion of the packing press ring that is abutted against the packing. During connection of the male connector housing with the female connector housing, compressed air exits via the vent hole portions. Thereby, an impingement sound or a touch feeling is strongly produced so that, during assembly, an operator easily detects whether the connector housings are in a fitted condition or a non-fitted condition.

Claims

1. A waterproof electrical connector comprising:

a male connector housing;

a female connector housing for connection with the male connector housing;

a hood portion provided on one of the male connector housing and the female connector housing;

a packing within the hood portion to provide a waterproof seal for the connector;

a packing press ring pressing against and retaining the packing within the hood portion; and

vent hole portions provided on a portion of the packing press ring that is abutted against the packing, wherein during connection of the male connector housing with the female connector housing, compressed air exits via the vent hole portions.

2. The waterproof electrical connector according to claim 1, wherein the compressed air exits via a gap between an inner surface of the hood portion and an outer surface of the packing press ring.

3. The waterproof electrical connector according to claim 1, wherein during connection of the male connector housing with the female connector housing, an impingement sound is produced.

4. The waterproof electrical connector according to claim 1, further including:

male electrical terminals within the female connector housing; and

female electrical terminals within the male connector housing for connection with the male electrical terminals.
