Abstract
Abstract A connector housing assembly having a ring-like packing formed integrally with a resin housing member to provide an improved sealing function at a reduced manufacturing cost. The housing is formed by resin molding using male and female molds. In one embodiment of the invention, the first male mold is removed and replaced with another male mole shaped so as to form a hollow portion corresponding to the desired shape of the packing. Rubber material is poured into the hollow portion through lead-in paths in at least one of the female mold or the second male mold. In another embodiment, the two molds used to form the housing are both removed, and the first male mold is replaced with a second male mold defining the hollow portion used to form the packing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
88 words
A connector housing assembly comprising: a substantially elongated annular cylindrical housing formed integrally of a resin material; and a rubber ring-like packing formed by pouring an adhesive rubber material into said housing through a metal mold such that said rubber ring-like packing adheres to an inner side wall of said housing at a fitting portion thereof so as to form a unitary connector housing assembly, whereby when said connector housing assembly is coupled to a second connector housing, said rubber ring-like packing sealingly engages said second connector housing.
Claim 2
Dependent Claim
88 words
A connector housing assembly comprising: a substantially elongated annular cylindrical housing formed integrally of a resin material; and a rubber ring-like packing formed by pouring an adhesive rubber material into said housing through a metal mold such that said rubber ring-like packing adheres to an inner side wall of said housing at a fitting portion thereof so as to form a unitary connector housing assembly, whereby when said connector housing assembly is coupled to a second connector housing, said rubber ring-like packing sealingly engages said second connector housing.
Claim 3
Independent Claim
86 words
A method for producing a connector housing assembly comprising the steps of: pouring synthetic resin between a male and a female metal mold to thereby form a housing; arranging another male metal mold having a hollow portion corresponding to a ring-like packing in place of said first-mentioned male metal mold; and pouring a rubber material through rubber material lead-in paths provided in at least one of said female metal mold and said other male metal mold to thereby form said ring-like packing integrally with said housing.
Claim 4
Independent Claim
86 words
A method for producing a connector housing assembly comprising the steps of: pouring synthetic resin between a male and a female metal mold to thereby form a housing; arranging another male metal mold having a hollow portion corresponding to a ring-like packing in place of said first-mentioned male metal mold; and pouring a rubber material through rubber material lead-in paths provided in at least one of said female metal mold and said other male metal mold to thereby form said ring-like packing integrally with said housing.
Claim 5
Independent Claim
86 words
A method for producing a connector housing assembly comprising the steps of: pouring synthetic resin between a male and a female metal mold to thereby form a housing; removing said housing; disposing said housing between another female metal mold and another male metal mold having a hollow portion corresponding to a ring-like packing; and pouring a rubber material through rubber material lead-in paths provided in at least one of said other female and male metal molds to thereby form said ring-like packing integrally with said housing.
Claim 6
Independent Claim
86 words
A method for producing a connector housing assembly comprising the steps of: pouring synthetic resin between a male and a female metal mold to thereby form a housing; removing said housing; disposing said housing between another female metal mold and another male metal mold having a hollow portion corresponding to a ring-like packing; and pouring a rubber material through rubber material lead-in paths provided in at least one of said other female and male metal molds to thereby form said ring-like packing integrally with said housing.
