Abstract
The present invention relates to a connector housing and a method of manufacturing the waterproof connector housing. The waterproof connector housing according to the present invention includes: an engagement frame for receiving a mating connector at a front portion thereof; a ring-like primer layer formed on a wall of at least an engagement face of the engagement frame; and addition-reaction fluid silicone rubber formed on the ring-like primer layer, wherein the addition-reaction fluid silicone rubber is combined with the primer layer by vulcanizing the fluid silicone rubber such that a ring-like packing is integrally formed with the connector housing. The method of manufacturing the waterproof connector housing includes the steps of: manufacturing a connector housing having an engagement frame for receiving a mating connector at a front portion thereof; attaching a primer layer to a wall of an engagement face of the engagement frame; drying the primer to form a ring-like primer layer; putting the connector housing with the primer layer between a male metal mold and a female metal mold having an opening; injecting fluid silicone rubber into the opening of the female metal mold; vulcanizing the fluid silicone rubber to form a ring-like packing in the opening; and removing the male and female metal molds to take out a molded product in which the ring-like packing is integrally formed with the connector housing.
