Abstract

Claims (33)

1 . A connector, comprising:

a connector housing having an internal surface defining a fluid passage between a connector end and connector housing face;

a first annular seal abutting said connector housing face; and

a membrane positioned to cover said first annular seal, said membrane connected to said connector housing,

wherein, upon engagement of a first connector housing and a second connector housing along a common juncture, a first membrane and a second membrane when correspondingly removed from said first annular seal abutting said first connector housing face

and a second annular seal abutting said second connector housing face engages said first annular seal against said second annular seal.

2 . The connector of claim 1 , wherein said first annular seal comprises:

a tubular body configured to engage said internal surface of said of said fluid passage of said connector housing; and

an annular lip circumferentially radially extending from said tubular body to engage said connector housing face, said annular lip having a thickness sufficient to engage said first annular seal with said second annular seal.

3 . The connector of claim 1 , wherein said first annular seal engages said second annular seal in a fluid tight seal between said fluid passage of said first connector housing and said fluid passage of said second connector housing.

4 . The connector of claim 1 , wherein said membrane entirely covers said first annular seal.

5 . The connector of claim 4 , wherein said membrane includes a peripheral margin coupled to said connector housing.

6 . The connector of claim 5 , wherein said peripheral margin of said membrane coupled to said connector housing along the entirety of said peripheral margin.

7 . The connector of claim 6 , said peripheral margin of said membrane is heat staked to said connector housing along the entirety of said peripheral margin.

8 . The connector of claim 4 , wherein said peripheral margin of said membrane is heat staked to said connector housing.

9 . The connector of claim 1 , wherein said membrane comprises one layer.

10 . The connector of claim 1 , wherein said one layer comprises polytetrafluoroethylene (PTFE).

11 . The connector of claim 1 , further comprising a pull strip coupled to said membrane.

12 . The connector of claim 11 , wherein said pull strip is directly connected to said peripheral margin of said membrane coupled to said connector housing, said pull strip folds to overlay said membrane and extend outward of said connector housing.

13 . The connector of claim 12 , further comprising a pull tab connected to said pull strip.

14 . The connector of claim 1 , wherein said connector housing extends about said connector housing outlet face coupled to said first annular seal to terminate in connector housing outer edge.

15 . The connector of 14, wherein a first connector housing outer edge of said first connector housing and a second connector housing outer edge of said second connector housing having substantially identical configuration engage along a common juncture.

16 . The connector of claim 14 , further comprising a first fastening part and a second fastening part coupled to said connector housing, wherein said first fastening part of said first connector and said second connector corresponding connect with said second fastening part of said first connector and said second connector to engage said first connector housing outer edge of said first connector and said second connector housing outer edge of said second connector housing along said common juncture.

17 . The connector of claim 16 , wherein said first fastening part comprises a pair of resiliently flexible catch members disposed in fixed spaced apart relation and each extending outward of said of said connector housing to terminate in corresponding pair of catch ends.

18 . The connector of claim 17 , wherein said second fastening part comprises a pair of projecting members coupled to said connector housing and disposed in opposed fixed spaced apart relation.

19 . The connector of claim 18 , wherein said pair of catch ends of said first connector housing and said second connector housing configured to slide between said pair of projecting members of said first connector housing and said second connector housing to mateably secure to said pair of projecting members of said first and second connector housing to maintain engagement of said first connector housing and said second connector housing along said common juncture.

20 . A connector, comprising

a connector housing having an internal surface defining a fluid passage between a connector end and connector housing face;

an annular seal coupled to said connector housing face; and

a membrane positioned to cover said annular seal,

wherein said membrane coupled to said connector housing,

wherein said membrane having a concave curvature facing said annular seal,

wherein, upon engagement of a first connector housing and a second connector housing along a common juncture, a first membrane and a second membrane when correspondingly removed from a first annular seal coupled to said first connector housing face and a second annular seal coupled to said second connector housing face engages said first annular seal with said second annular seal.
