First Claim
1. A waterproof connector comprising:
- a male connector housing having a forward end and a rearward end;
an outer hood circumferentially provided partly or entirely around the male connector housing with an annular space therebetween, the outer hood including an outwardly bulged portion;
a female connector housing having a forward end and a rearward end, the forward end of said male connector being brought within the forward end of said female connector housing when inserted therein, and said female connector housing having a hood portion extending at least partly therearound;
a seal ring contained in the annular space, contacted by the hood portion of the female connector housing when the hood portion is inserted into the annular space on fitting the male and female connector housings with each other anda locking member comprising at least one resilient locking arm provided adjacent the outwardly bulged portion, the resilient locking arm being supported at a rearward end thereof on the male connector housing via a rear support and being supported at a forward end thereof on an inner surface of the outwardly bulged portion via a front support, the resilient locking arm being provided at a point between the rear and front supports with locking means engageable with associated engagement means of the female connector housing to lock the male and female connector housings together.

Abstract
A waterproof connector comprises a male connector housing and an outer hood circumferentially provided on the male connector housing with an annular space therebetween, which contains a seal ring and into which is inserted a hood portion of a mating female connector to be brought into contact with the seal ring. A resilient locking arm of a double support structure is provided inside an outwardly bulged portion of the outer hood such that it is rearwardly supported on the part of the male connector housing and forwardly supported on the part of the outwardly bulged portion. This allows a male connector housing to be locked to a mating connector with an increased force, while making it possible to protect the resilient locking arm from external forces.
