Water-proof connector

Claim 2

A water-proof connector, comprising: a female connector housing having an opening at one end thereof and including an expanding key on an inner surface thereof; a male connector housing insertable into the opening of said female connector housing; a sealing ring disposed within the said female housing so as to be positioned between said male and female connector housings; and a retaining member for retaining said sealing ring within said female connector housing, said retaining member being hollow and having a longitudinally extending slot provided in an outer wall thereof, wherein said expanding key is forced into said slot causing said retaining member to expand outwardly against said female connector housing so as to frictionally retain said retaining member to said female connector housing.

Claim 3

The water-proof connector of claim 1, wherein a lateral width of said key is greater than a lateral width of said slot.

Claim 4

The water-proof connector of claim 1, wherein said sealing ring and said retaining member are rectangular in shape.

Claim 5

The water-proof connector of claim 1, further comprising a locking mechanism for securing said male and female connector housings together.

Claim 6

A water-proof connector, comprising: a female connector housing having an opening at a rear end thereof; a male connector housing insertable into the opening of said female connector housing; a sealing ring disposed within said female connector housing so as to be positioned between said male and female connector housings; and a retaining member for retaining said sealing ring within said female connector housing, wherein an elongate support protrusion is formed on one of an inside surface of said female connector housing and an outside surface of said male connector housing, and wherein said retaining member has a slotted portion for receiving said support protrusion when said male and female connector housings are connected together such that said support protrusion directly abuts against another of said inside surface of said female housing and said outside surface of said male connector housing so as to urge a surface of said male housing opposite said outside surface, toward an opposing surface of said female housing.

Claim 7

A water-proof connector, comprising: a female connector housing having an opening at a rear end thereof; a male connector housing insertable into the opening of said female connector housing; a sealing ring disposed within said female connector housing so as to be positioned between said male and female connector housings; and a retaining member for retaining said sealing ring within said female connector housing, wherein an elongate support protrusion is formed on one of an inside surface of said female connector housing and an outside surface of said male connector housing, and wherein said retaining member has a slotted portion for receiving said support protrusion when said male and female connector housings are connected together such that said support protrusion directly abuts against another of said inside surface of said female housing and said outside surface of said male connector housing so as to urge a surface of said male housing opposite said outside surface, toward an opposing surface of said female housing.

Claim 8

The water-proof connector of claim 5, wherein a thickness of said support protrusion is greater than a thickness of said retaining member.

Claim 9

The water-proof connector of claim 5, wherein said support protrusion is formed on said outside surface of said male connector housing and wherein said support protrusion has an inclined surface at a front end thereof to facilitate insertion of said male connector housing into said female connector housing.

Claim 10

The water-proof connector of claim 5, wherein said support protrusion is formed on said inside surface of said female connector housing at a position which is displaced forwardly of said opening.

Claim 11

A water-proof connector, comprising: a female connector housing having an opening at a rear end thereof; a male connector housing insertable into the opening of said female connector housing; a sealing ring disposed within said female connector housing so as to be positioned between said male and female connector housings; and a retaining member for retaining said sealing ring within said female connector housing, wherein an elongate support protrusion is formed on one of an inside surface of said female connector housing and an outside surface of said male connector housing and said retaining member has a slotted portion for receiving said support protrusion when said male and female connector housings are connected together such that said support protrusion directly supports said male connector housing on said female connector housing, said support protrusion being formed on said inside surface of said female connector housing at a position which is displaced forwardly of said opening, wherein said support protrusion is a first support protrusion and said water-proof connector further comprises a second support protrusion provided on said outer surface of said male connector housing, and wherein when said male connector housing is inserted into said female connector housing, said second support protrusion abuts said first support protrusion to positively retain said male connector housing within said female connector housing.

Claim 12

A water-proof connector, comprising: a female connector housing having an opening at a rear end thereof; a male connector housing insertable into the opening of said female connector housing; a sealing ring disposed within said female connector housing so as to be positioned between said male and female connector housings; and a retaining member for retaining said sealing ring within said female connector housing, wherein an elongate support protrusion is formed on one of an inside surface of said female connector housing and an outside surface of said male connector housing and said retaining member has a slotted portion for receiving said support protrusion when said male and female connector housings are connected together such that said support protrusion directly supports said male connector housing on said female connector housing, said support protrusion being formed on said inside surface of said female connector housing at a position which is displaced forwardly of said opening, wherein said support protrusion is a first support protrusion and said water-proof connector further comprises a second support protrusion provided on said outer surface of said male connector housing, and wherein when said male connector housing is inserted into said female connector housing, said second support protrusion abuts said first support protrusion to positively retain said male connector housing within said female connector housing.

Claim 13

The water-proof connector of claim 9, wherein a combined thickness of said first and second support protrusions is greater than a thickness of said retaining member.

Claim 14

The water-proof connector of claim 10, wherein said second support protrusion has an inclined surface at a front end thereof to facilitate insertion of said male connector housing into said female connector housing.
