ABSTRACT:
The waterproof connector housing according to the present invention comprises a connector housing which includes a housing body having a plurality of terminal receiving chambers and an engagement frame formed around a peripheral wall of said housing body for receiving a mating connector, and a waterproof packing integrally formed with said connector housing between said housing body and said engagement frame, wherein an insertion groove is formed in at least one portion of the peripheral wall of the housing body for injecting a packing material therethrough, said insertion groove extending from a mating face between the housing body and the mating connector in a receiving direction of the mating connector. With such a construction an easy and reliable insertion of the packing material is attained, thus enhancing waterproofness of the connector housing. Further, the injected packing material remains inside an inlet of said insertion groove without overflowing therefrom. Because the waterproof packing is not exposed to the exterior, an attack by high pressure water at high pressure cleaning can be avoided.
