Abstract

A releasable connector having a male member with spaced prong ends and a tubular female member having an open end for receiving said prong ends and divided at said open end into legs by axially extending slots and a unitary locking means removably interposable between the prong ends and an annular portion for bridging the joint interface between the interlocked male and female members.

Claims

1. A releasable connector comprising:

a male member having two prongs terminating in normally spaced apart prong ends;

a tubular female member having an open end dimensioned for axially receiving said prong ends, said tubular member being divided at said open end into at least three legs by axially extending slots;

said prong ends being resiliently compressible towards each other for insertion into said female member, said prong ends returning to said normal position within and interlocking with said female member to prevent separation of said male and female members, said prong ends being disengagable from said female member upon squeezing together of said prongs; and

unitary locking means removably interposable between said interlocked prong ends for securing said male and female members in mating engagement, and with an annular coextensive portion thereof for bridging the joint interface between the interlocked male and female members.

2. A releasable connector as set forth in claim 1 including detent means on said prong ends engagable with said female member upon resilient separation of the prong ends therein for retaining said male and female members in mating engagement.

3. A releasable connector as set forth in claim 2 in which said locking means comprises a locking member received on and slideable along said male member between a release position away from said prong ends allowing the prong ends to be squeezed together for at least partially disengaging said detent means and permitting separation of said male and female members, and a locking position wherein the locking member is interposed between and maintains said prong ends in a spaced apart relationship to secure said detent against disengagement and prevent separation of said two members.

4. A releasable connector comprising:

a male member having an elongated cylindrical body, a longitudinally extending open ended slot diametrically dividing a portion of said body into two substantially semi-cylindrical prongs connected by an undivided portion of said body and having prong ends normally separated by said slot but resiliently squeezeable together in a direction perpendicular to the plane of said slot;

female member including a cylindrical tubular wall open at one end for axially receiving said prong ends in said squeezed together condition and being closed at an opposite end, said tubular wall being divided at said open end into four legs by four axially extending slots, and female detent means radially inwardly projecting from each other of said four legs at said open end;

male detent means projecting radially outwardly on both prong ends and engageable with said female detent means on all four ends upon resilient separation of the prong ends following insertion axially into said tubular wall for retaining said male member against separation from said female member; and

a locking ring including a diametric web extending through said slot, said ring being slideable between a release position away from said prong ends allowing the prong ends to be squeezed together thereby partially disengaging said male and female detent means, said legs being resiliently spreadable in response to subsequent axial pulling force between said male and female members thus permitting full disengagement of said detent means and separation said male and female members, and a locking position wherein said web is interposed between and maintains said prong ends in spaced apart relationship to prevent said partial disengagement of said detent means and ensure against separation of said two members.

5. A releasable connector as set forth in claim 4 in which said prong ends have radially enlarged portions defining substantially square detent shoulders.

6. A releasable connector as set forth in claim 4 in which said female member has an inturned lip on said wall adjacent said open end defining a substantially square detent shoulder on each of said legs facing towards said closed end.

7. A releasable connector as set forth in claim 6 in which said prong ends have radially enlarged portions defining substantially square detent shoulders facing said outer end, the prong ends and inturned lips being located and formed to constitute said detent means.

8. A releasable connector comprising:

a male member having an elongated cylindrical body, a longitudinally extending open ended slot diametrically dividing a portion of said body into two substantially semicylindrical prongs connected by an undivided portion of said body and having prong ends normally separated by said slot but resiliently squeezable together in a direction perpendicular to the plane of said slot, said prong ends having radially enlarged portions defining substantially square detent shoulders facing said undivided portion;

a female member including cylindrical tubular wall open at one end for axially receiving said prong ends in said squeezed together condition and being closed at an opposite end, said tubular wall being divided at said open end into four legs by four axially extending slots, an inturned lip on said wall adjacent said open end defining a substantially square detent shoulder on each of said legs facing toward said closed end, said detent shoulders on the prong ends facing said detent shoulders on said legs when the male member is received within the female member for retaining said male member against axial separation from said female member;

a locking ring including including a diametric web extending through said slot, said ring being slideable between a release position away from said prong ends allowing the prong ends to be squeezed together thereby partially disengaging said male and female members, said legs being resiliently spreadable in response to subsequent axial pulling between said male and female members thus permitting full disengagement and separation of said male and female members, and a locking position wherein said web is interposed between and maintains said prong ends in a spaced apart relationship to prevent said partial disengagement of said male and female members;

the male and female members being dimensioned relative to one another to provide a substantial space between the prong ends of the male member and the inner surface of the closed end of the female member, the axially extending slots of the female member being of sufficient length to expose this space; and

the cylindrical body of the male member including at least one relief area on its outer surface to provide a clearance space between the internal surface of the locking member and the outer surface of the male member, this relief area being of sufficient size to permit debris to be dislodged and removed from between the ring and the male member.

9. A releasable connector as set forth in claim 8 in which the male member includes diametrically opposed relief areas which extend to the undivided portion of said body, and in which the sides of the open ended slot in said male member diverge towards said undivided portion to provide internal clearances between the diametric web of the locking ring and the prongs of the male member for removal of debris therefrom, said male member including a bore through its undivided outer end for threading a line through the male member, and said female member including a bore through its closed end for threading a line through said female member.
