Abstract

A hose connection has: a tubular body with a first end and a second end; a shrink sleeve arranged around the first end of the tubular body for crimping and thereby clamping a hose end on the first end of the tubular body; and an adhesive layer arranged on the outer surface of the first end of the tubular body and at least enveloping the first end in tangential direction.

First claim

The invention claimed is:

1. A hose connection, comprising:
a tubular body including a first end and a second end;
a shrink sleeve arranged around the first end of the tubular body configured to clamp a hose end on the first end of the tubular body between the first end of the tubular body and the shrink sleeve;
an adhesive layer arranged on an outer surface of the first end of the tubular body, the adhesive layer at least enveloping the first end in a tangential direction of the tubular body; and
parallel annular ridges, arranged on the outer surface of the first end of the tubular body,
wherein the outer surface of the first end and the parallel ridges together form curved undulations.

2. The connection of claim 1 , wherein the adhesive layer extends on the outer surface along at least a length of the shrink sleeve.

3. The connection of claim 1 , further comprising:
a bushing, arranged against an internal surface of the first end of the tubular body.

4. The connection of claim 1 , wherein the tubular body is injection molded.

5. The connection of claim 1 , further comprising:
an annular groove, arranged at a distance from an outer end of the first end of the tubular body,
wherein the shrink sleeve includes a radial flange extending inwardly and into the annular groove.

6. The connection of claim 1 , wherein a surface strength of the outer surface of the first end of the tubular body is at least 10 −6 Nm (10 dyne·cm) greater than a surface strength of the adhesive layer.

7. A method for manufacturing the hose connection of claim 1 , the method comprising:
providing the tubular body;
plasma treating the outer surface of the first end of the tubular body;
coating the outer surface of the first end with an adhesive so as to provide the adhesive layer; and
arranging the shrink sleeve around the first end of the tubular body.

8. The method of claim 7 , wherein a surface strength of the outer surface of the first end of the tubular body after plasma treatment is at least 10 −6 Nm (10 dyne·cm) greater than a surface strength of the adhesive layer.

9. A hose connection, comprising:
a tubular body including a first end and a second end;
a shrink sleeve arranged around the first end of the tubular body configured to clamp a hose end on the first end of the tubular body;
an adhesive layer arranged on an outer surface of the first end of the tubular body, the adhesive layer at least enveloping the first end in a tangential direction of the tubular body;
parallel annular ridges, arranged on the outer surface of the first end of the tubular body; and
a bushing, arranged against an internal surface of the first end of the tubular body,
wherein the outer surface of the first end and the parallel ridges together form curved undulations.

10. A hose connection, comprising:
a tubular body including a first end and a second end;
a shrink sleeve arranged around the first end of the tubular body configured to clamp a hose end on the first end of the tubular body;
an adhesive layer arranged on an outer surface of the first end of the tubular body, the adhesive layer at least enveloping the first end in a tangential direction of the tubular body;
parallel annular ridges, arranged on the outer surface of the first end of the tubular body; and
an annular groove, arranged at a distance from an outer end of the first end of the tubular body,
wherein the outer surface of the first end and the parallel ridges together form curved undulations, and
wherein the shrink sleeve includes a radial flange extending inwardly and into the annular groove.
