Abstract

A connector for joining together a pair of fluid carrying hose members in an automotive vehicle is disclosed. The connector includes a tubular body having a first end, a second end, and a shoulder interposed therebetween, the first end including a plurality of angled barbs projecting from an outer surface thereof. The connector also includes a tubular liner press-fit into the first end of the body and a generally cylindrical, cup-shaped collar surrounding the outer surface of the first end of the body. A roll formed beadlock is formed against an interior surface of the collar to prevent axial displacement of the collar along the body of the connector. A method for making such a connector is also disclosed.

Claims

1. A connector for joining together a pair of fluid carrying hose members in an automotive vehicle, comprising:

a generally tubular body having a first end, a radially outward flared second end adapted to matingly engage a quick connect coupling formed on one of said fluid carrying hose members and a shoulder interposed therebetween, said first end including a plurality of angled barbs projecting from an outer surface thereof and being adapted to be inserted into one of said hose members;

a generally tubular liner having a predetermined length press-fit into said first end of said body and being fabricated from a material different from that of said body;

a generally cylindrical, cup-shaped collar surrounding the outer surface of said first end of said body, said collar having an open end and a terminating end, said terminating end abutting said shoulder of said body, said collar being adapted to be crimped over the other of said fluid carrying hose members such that a plurality of axially spaced crimp projections are formed therein to resist axial movement of said hose member; and

means for resisting axial displacement of said collar on said body, said means comprising a roll formed bead formed against an interior surface of said collar terminating end.

2. A connector according to claim 1, wherein said body is fabricated from an aluminum alloy.

3. A hose assembly for joining together a first fluid carrying member and a heat exchanger in a motor vehicle, said assembly comprising:

a first hose member;

a connector interposed between said first hose member and a second hose member fluidly connected to said heat exchanger, said connector comprising;

a generally tubular body having a first end, a radially outward flared second end and a shoulder interposed therebetween, said first end including a plurality of angled barbs projecting from an outer surface thereof and being adapted to be inserted into said first hose member;

a generally tubular liner having a predetermined length press-fit into said first end of said body and being fabricated from a material different from that of said body;

a generally cylindrical, cup-shaped collar surrounding the outer surface of said first hose member when said first hose member is disposed over said first end of said body, said collar having an open end and a terminating end, said terminating end abutting said shoulder of said body, said collar being adapted to be crimped over said first hose member such that a plurality of axially spaced crimp projections are formed therein to resist axial movement of said first hose member; and

a beadlock formed on an outer surface of said body against an interior surface of said collar terminating end and adapted to prevent axial displacement of said collar on said body;

said second hose member including a coupling adapted to matingly engage said second end of said connector, whereby said collar is adapted to be crimped over said first hose member to provide a leak free seal, said coupling comprising;

a cage means forming a chamber mounted against axial displacement on the outer surface of said second hose member near one end thereof and having an aperture facing said second hose member end;

radially expandable garter spring means located within the chamber of said cage means around the outer surface of said second hose member end, for expanding radially over the flared second end of said body of said connector to become located between the outer surface of said flared second end and the inner surface of said cage means thereby preventing axial withdrawal of the flared second end from the second hose member of the heat exchanger.

4. A hose assembly according to claim 3, wherein said connector is fabricated from an aluminum alloy.

5. A hose assembly according to claim 4, wherein said liner is fabricated from a steel alloy.
