Heated Hose With Angled Connector And Plug-In Coupling

A heated hose for passage of a free-flowing medium, having:

• a flexible heated-hose body having:
• a high-pressure hose, wherein the high-pressure hose has a hose core, for the passage of the free-flowing medium, and a reinforcement surrounding the hose core;
• at least one heat conductor for heating the medium passing in the high-pressure hose;
• a thermal insulation layer made of a thermally insulating material and surrounding the high-pressure hose and the at least one heat conductor;
• an outer sleeve surrounding the thermal insulation layer;
• an attachment piece connected to the high-pressure hose, wherein the attachment piece has a through-channel, which allows the free-flowing medium to pass through the attachment piece, and a coupling connector for producing a fluidic connection between the heated hose and an external apparatus, by coupling the external apparatus along a coupling axis of the coupling connector;
• an end cap, wherein the end cap covers an end portion of the flexible heated-hose body;
• wherein the attachment piece is an angled attachment piece which has a first limb and, angled with respect to the first limb, a second limb, wherein the through-channel of the attachment piece runs through the first limb and the second limb to allow the free-flowing medium to pass through the attachment piece, wherein the first limb is connected to the high-pressure hose, wherein the second limb is formed at least partially in a region surrounded by the end cap, and wherein the coupling connector is formed in the region of the second limb.

A method for producing a heated hose having the following method steps:

• a) producing or providing a flexible heated-hose body of the heated hose, the flexible heated-hose body having:
• a high-pressure hose, wherein the high-pressure hose has a hose core, for passage of a free-flowing medium, and a reinforcement surrounding the hose core;
• at least one heat conductor for heating the medium passing in the high-pressure hose;
• a thermal insulation layer made of a thermally insulating material and surrounding the high-pressure hose and the at least one heat conductor;
• an outer sleeve surrounding the thermal insulation layer;
• b) providing an angled attachment piece, wherein the attachment piece has a first limb and, angled with respect to the first limb, a second limb, wherein the attachment piece has a through-channel which runs through the first limb and the second limb to allow the free-flowing medium to pass through the attachment piece, wherein the first limb is releasably connectable to the high-pressure hose, wherein the second limb has a coupling connector for producing a fluidic connection between the heated hose and an external apparatus, by coupling the external apparatus along a coupling axis of the coupling connector;
• c) producing the releasable connection between the high-pressure hose and the first limb of the attachment piece, wherein method step c) takes place after method steps a) and b);
• d) arranging an end cap on an end portion of the heated-hose body in such a way that the end cap covers the end portion of the flexible heated-hose body, wherein the second limb of the attachment piece is formed at least partially in a region enclosed by the end cap, wherein method step d) takes place after method step c).

A plug coupling system for producing a fluidic connection to a heated hose, wherein the plug coupling system has:

• a heated hose for passage of a free-flowing medium, wherein the heated hose has an attachment piece for producing the fluidic connection to the heated hose, wherein the attachment piece has a through-channel, allowing the free-flowing medium to pass through the attachment piece, and a coupling connector, wherein the coupling connector has a circumferential securing groove on an outer face;
• a coupling socket corresponding to the coupling connector, wherein the coupling connector and the coupling socket form a plug coupling, wherein the coupling connector is insertable into the coupling socket along a coupling axis of the coupling connector to produce a coupled arrangement;
• a closure slide for securing the attachment piece in the coupling socket in the coupled arrangement, wherein the closure slide has two securing limbs, wherein the respective securing limb has a latching recess on an inner face directed toward the other securing limb, wherein the latching recesses result in a formation, between the securing limbs, of a receiving region which is adapted to the coupling connector and has a constriction, wherein the coupling connector overcomes the constriction by the securing limbs deflecting away from each other, wherein the coupling socket has two through-openings for the securing limbs, wherein the through-openings are aligned with the securing groove in the coupled arrangement, such that, in the coupled arrangement, the securing limbs are insertable through the through-openings into the circumferential securing groove to produce a securing position, wherein, in the securing position, the coupling connector is received in a latching engagement in the receiving region and the attachment piece and the coupling socket bear on each other along the coupling axis of the coupling connector, via the securing limbs to secure the attachment piece in the coupling socket, wherein the through-openings and the securing limbs are configured such that, in the securing position, a deflection of the securing limbs away from each other causes a displacement of the attachment piece along the coupling axis of the coupling connector into the coupling socket.
