Secondary retention clip for fluid tube connection
View Patent ↗A tube is insertable into a housing and secured by a collet connector. The tube has a first upset portion for actuating the collet and a second upset portion outwardly from the first upset portion. A retention clip has a first pair of arms which attach to a portion of the housing and a second pair of arms which attach to the tube outwardly of the second upset portion to further secure the tube within the housing. The end of each of the second pair of arms include a ramped surface. If the tube is not fully inserted within the housing before attaching clip, and thus the first upset portion has not fully actuated the collet, the ramps will cam along the second upset portion, thus pushing the tube into the housing and likewise the first upset portion through the collet.
1. A retention assembly for a fluid tube connection, said assembly comprising:
a housing defining an axial bore;
a tube having a first upset portion and a second upset portion outwardly of said first upset portion, said tube insertable into said bore;
a quick connect coupling disposed within said bore, said coupling being actuated by said first upset portion of said tube to retain said tube within said bore; and
a retention clip having a pair of tube legs and a pair of housing legs for attaching said clip to said tube and a portion of said housing to further secure said tube within said bore wherein said tube legs are received by said tube outwardly of said second upset portion to attach said clip to said tube, and wherein the end of at least one of said tube legs includes an angled ramp such that said ramp will contact said second upset portion as said clip is attached if said tube is not fully inserted within said housing, thereby forcing said tub into said housing and likewise said first upset portion through said coupling.
2. The assembly of claim 1 wherein said housing comprises a channel disposed between two larger housing portions.
3. The assembly of claim 2 wherein said housing legs are received by said channel for attaching said clip to said housing.
4. A retention assembly for a fluid tube connection, said assembly comprising:
a housing defining an axial bore;
a tube having at least a first upset portion, said tube insertable into said bore;
a quick connect coupling disposed within said bore, said coupling being actuated by said first upset portion of said tube to retain said tube within said bore; and
a retention clip having at least one angled ramp such that said ramp will contact a surface on said tube as said clip is attached if said tube is not fully inserted within said housing, thereby forcing said tube into said housing and likewise said first upset portion through said coupling wherein said clip further includes a pair of tube legs and a pair of housing legs for attaching said clip to said tube and a portion of said housing to further secure said tube within said bore, and wherein said tube legs are received outwardly of a second upset portion to attach said clip to said tube, said second upset portion being the surface on said tube which contacts said ramp.
5. The assembly of claim 4 wherein said at least one angled ramp is disposed on at least of one said pair of tube legs.
6. The assembly of claim 4 wherein said housing comprises a channel disposed between two larger housing portions.
7. The assembly of claim 6 wherein said housing legs are received by said channel for attaching said clip to said housing.
8. A retention assembly for a fluid tube connection, said assembly comprising:
a housing defining an axial bore and a channel disposed between two larger housing portions;
a tube having a first upset portion and a second upset portion outwardly of said first upset portion, said tube insertable into said bore;
a quick connect coupling disposed within said bore, said coupling being actuated by said first upset portion of said tube to retain said tube within said bore; and
a retention clip attached to said tube and a portion of said housing to further secure said tube within said bore, said clip including a ramp to contact said second upset portion as said clip is attached if said tube is not fully inserted within said housing, thereby forcing said tube into said housing and likewise said first upset portion through said coupling wherein the clip includes a pair of housing legs, and wherein said housing legs are received by said channel for attaching said clip to said housing.
9. The assembly of claim 8 wherein said clip includes a pair of tube legs, and wherein said tube legs are received by said tube outwardly of said second upset portion to attach said clip to said tube.
10. The assembly of claim 9 wherein the end of at least one of said tube legs includes said ramp, said ramp being angled.
