High pressure quick connector

A high pressure quick connect comprising:

• a tube having an upset adjacent one end thereof;
• a male locking assembly positioned about said tube, said male locking assembly including a cavity enclosing said upset and a contoured outer surface defining first and second grooves spaced axially along said male locking assembly wherein said recessed grooves are separated by a flange means;
• a female member having an internal bore adapted to receive said male locking assembly, said internal bore having a retaining groove;
• an expandable annular locking ring mounted about said contoured outer surface, said locking ring initially being mounted in said first groove and wherein said flange means allows said locking ring to slide from said first groove to said second groove upon axial movement of said male locking assembly into said female member, wherein said flange means is adapted to act upon said locking ring as said tube is attempted to be withdrawn from said female member;
• said second groove being adjacent said retaining groove upon full insertion of said male locking member into said female locking member with said expandable annular locking ring being positioned within said second groove and adjacent said retaining groove such that said locking ring is nested between said adjacent second groove and said retaining groove wherein said flange means is in surface to surface contact with said spring and forces said spring outwardly into engagement with said retainer groove upon attempted withdrawal of said tube from said female member.

A high pressure quick connect comprising:

• a tube having an upset adjacent one end thereof;
• a male locking assembly positioned about said tube, said male locking assembly including a cavity enclosing said upset and a contoured outer surface defining spaced recessed groove wherein said recessed grooves are separated by a flange means;
• an expandable annular locking ring mounted about said contoured outer surface, said flange means allowing said locking ring to slide between said spaced recessed grooves, wherein said flange means is adapted to act upon said annular locking ring as said tube is urged from said female member;
• a female member having an internal bore adapted to receive said male locking assembly, said internal bore of said female member having a retainer groove;
• whereby, one of said recessed grooves is adjacent said retainer groove upon lull insertion of said male locking assembly into said female member with said expandable annular locking ring being operatively trapped between said one recessed groove and said retainer groove to prevent said male locking assembly from being withdrawn from said female member;
• wherein said tube is a preassembled unit including said male locking assembly and sealing means.

• an expandable annular locking ring mounted about said contoured outer surface, said flange means allowing said locking ring to slide between said spaced recessed grooves, wherein said flange means is adapted to act upon said annular locking ring as said tube is urged from said female member;
• a female member having an internal bore adapted to receive said male locking assembly, said internal bore of said female member having a retainer groove;
• whereby, one of said recessed grooves is adjacent said retainer groove upon full insertion of said male locking assembly into said female member with said expandable annular locking ring being operatively trapped between said one recessed groove and said retainer groove to prevent said male locking assembly from being withdraw from said female member;
• wherein said grooves are separated from said flange by inclined surfaces which facilitate the movement of said spring between said first and second recessed grooves.

A high pressure quick connect comprising:

• a tube having an upset adjacent one end thereof;
• a male locking assembly positioned about said tube, said male locking assembly including a cavity enclosing said upset and a contoured outer surface defining first and second grooves spaced axially along said male locking assembly wherein said recessed grooves are separated by a flange means;
• a female member having an internal bore adapted to receive said male locking assembly, said internal bore having a retaining groove;
• an expandable annular locking ring mounted about said contoured outer surface, said locking ring initially being mounted in said first groove and wherein said flange means allows said locking ring to slide from said first groove to said second groove upon axial movement of said male locking assembly into said female member, wherein said flange means is adapted to act upon said locking ring as said tube is attempted to be withdrawn from said female member;
• said second groove being adjacent said retaining groove upon full insertion of said male locking member into said female locking member with said expandable annular locking ring being positioned within said second groove and adjacent said retaining groove such that said locking ring is nested between said adjacent second groove and said retaining groove;
• wherein said tube is a preassembled unit including said male locking assembly and sealing means.
