Bulkhead-fluid-line connector

Claim 1

A bulkhead-fluid-line connector (10) for joining and supporting a tubular fluid line assembly (12) adapted for passing through an aperature (14) of a housing wall (16), said housing wall (16) having outside and inside surfaces (24,26), said fluid line assembly (12) including first and second fluid lines (20,22), said bulkhead-fluid-line connector (10) comprising: an enlarged end portion (52) integrally formed on the first line (20) and having an externally disposed and frusto-conically shaped end surface (82); another enlarged end portion (54) integrally formed on the second line (22) and having an internally disposed and frusto-conically shaped end surface (86) which is sealedly matedly complementarity with respect to said end surface (82) of the first line (20); and means (56) for releasably coupling said complementary end surfaces (82,86) of the fluid line end portions (52,54) in direct surface-to-surface sealed contact and thereby solely creating a single fluid path joint between the first and second fluid lines (20,22) generally where the fluid line assembly (12) is adapted to pass through the housing wall aperature (14), wherein said releasable coupling means (56) includes a fluid leakage path (92) extending adjacent the single joint of the sealedly contacting fluid line end surfaces (82,86) and adapted to be sealed from said inside surface (26) of the housing wall (16) and further adapted to lead only to the outside of said housing wall (16) said releasable coupling means (56) further includes a fitting (58), first and second retainers (64,66), and first and second collars (60,62), said fitting (58) adapted to slidably extend through said housing wall aperature (14) and defining a stepped longitudinal bore (77) having an internal shoulder (78) through which the fluid line assembly (12) passes, said fitting (58) having an enlarged head end portion (68) defining an external shoulder (70) and another end portion (72), said fitting shoulder (70) adapted to abut one of said inside or outside housing wall surfaces (26,24), said first retainer (64) releasably connected to said another end portion (72) of the fitting (58) and adapted to abut said other of the inside or outside housing wall surfaces (26,24), said second retainer (66) also releasably connected to said another end portion (72) of the fitting (58) and releasably coupling said complementary end surfaces (82,86) of the fluid line end portions (52,54) in direct surface-to-surface sealed contact, said second collar (62) sealedly positioned in said fitting bore (77) against said internal shoulder (78) of the fitting (58) and abutting said second line another end portion (54), said first collar (60) positioned between said first line end portion (52) and said second retainer (66).
