Abstract
A waterproof connector housing (1) includes a housing main body (2), a hood portion (4) for engaging with a mating housing via a shoulder portion (3) provided on the housing main body, an elastic seal ring (5) for maintaining water-tightness with the mating housing inside the hood portion, and a holding portion (5a) for the elastic seal ring extending from the body of the seal ring to the end surface of the housing main body. With this waterproof connector housing, the elastic seal ring can be easily molded, and the amount of wasted raw material can be dramatically reduced. Also, the hood portion can take various forms and be made smaller.

A waterproof connector housing comprising:
- a housing main body having a terminal-receiving opening extending axially therethrough and an end surface at one end thereof;
- a hood portion of greater diameter than said housing main body concentrically surrounding said housing main body and being connected therewith by a shoulder portion which is spaced longitudinally from said end surface;
- a seal ring for maintaining water-tightness with said mating housing inside said hood portion, said seal ring being formed of an elastic material and being disposed within said hood portion in tightly surrounding relation with respect to said housing main body;
- and
- said seal ring having a holding portion for holding said seal ring within said connector housing, said holding portion including a body of elastic material integral with said seal ring and being of a length sufficient to extend from said seal ring to said housing main body end surface.
