Coupling assembly
A male coupling for attaching to a female coupling in which rotation of the male coupling with respect to the female coupling is limited. In one embodiment, the male coupling has one or more tabs extending from a flange, the tabs limiting rotation when the male coupling is mated to a female coupling assembly for fluid conductors.
1. A combination comprising:
a female coupling assembly comprising:
a female coupling body, a flange, an extension, a latch plate and a latch pin, said female coupling body defining a female coupling fluid pathway, said extension forming a pair of female coupling assembly faces and a slot, a female coupling contact surface present on each of said female coupling assembly faces,
said latch plate reciprocating within said slot and biased in a locked position, and
said latch pin inserted into a latch pin bore and securing said latch plate in said slot; and
a male coupling assembly defining a male coupling fluid pathway and comprising:
a male coupling connector,
a flange in mechanical communication with said male coupling connector, a male coupler extending from said flange and defining an abutting surface, and
a non-rotational feature extending from said abutting surface, a pair of male coupling contact surfaces present on said non-rotational feature,
said male coupling assembly mating to said female coupling assembly such that said female coupling fluid pathway is generally continuous with said male coupling fluid pathway, wherein said female coupling body accommodates said male coupler, wherein said non-rotational feature is disposed between said female coupling assembly faces such that said female coupling contact surfaces are proximate said male coupling contact surfaces and such that said male coupling assembly is rotationally limited with respect to said female coupling assembly.
2. The combination of claim 1 , wherein said non-rotational feature axially extends from said flange.
3. The combination of claim 1 , wherein said non-rotational feature comprises a tab.
4. The combination of claim 1 , wherein said non-rotational feature comprises a plurality of tabs.
5. The combination of claim 1 , further comprising means for forming a fluid-tight seal when said male coupling is mated to said female coupling assembly.
6. The combination of claim 5 , wherein said fluid-tight seal forming means comprises a terminal slot formed in said coupler and an O-ring disposed in said terminal slot.
7. The combination of claim 1 , wherein said non-rotational feature defines a pair of lateral contact surfaces.
8. The combination of claim 1 , wherein rotation is limited to between about 1 degree and 45 degrees.
9. The combination of claim 1 , wherein rotation is limited to between about 1 degree and 20 degrees.
10. The combination of claim 1 , wherein rotation is limited to between about 1 degree and 10 degrees.
11. The combination of claim 1 , wherein rotation is limited to about 5 degrees.
12. A method of mating a male coupling to a female coupling,
said male coupling defining a male coupling fluid pathway and a tab extending from a flange,
said female coupling defining a female coupling fluid pathway and comprising a pair of radially opposed faces extending from a female coupling body and a latch mechanism to secure said male coupling to said female coupling when said male coupling and said female coupling are mated, said latch mechanism comprising a latch plate biased in a locked position and secured in said female coupling by a latch pin, said latch plate reciprocating in a slot disposed in said female coupling,
said method comprising mating said male coupling and said female coupling such that said male coupling fluid pathway aligns with said female coupling fluid pathway and such that said tab is disposed between said radially opposed faces to limit rotation of said male coupling with respect to said female coupling and such that said latch plate is reciprocated to said locked position, thereby securing said male coupling to said female coupling.
13. The method of claim 12 , wherein rotation is limited to between about 1 degree and 20 degrees.
14. The method of claim 12 , wherein rotation is limited to between about 1 degree and 45 degrees.
15. The method of claim 12 , wherein rotation is limited to between about 1 degree and 10 degrees.
16. The method of claim 12 , wherein rotation is limited to about 5 degrees.
