- Fig. 1 shows in a partially sectioned side view of an embodiment of a fluid line coupling according to the invention, which has a coupling body 1 made of a hard elastic plastic material.
- the coupling body 1 has a substantially 1, which is adapted to receive a plug-in part, not shown in FIG. 1, with which a line of a fluid line arrangement likewise not shown in FIG. 1 can be connected to the fluid line coupling.
- an approximately square socket 3 is formed on the receiving part 2 at the end for an inserted into the socket 3 locking part 4.
- a connecting piece 6 is attached as an attachment to an angle section 5, to which a further, not shown in Fig. 1 line of the fluid conduit assembly can be connected, which then extends over a through the coupling body 1 extending Fluid line cavity 7 is fluidly connected to the line connected to the insertion part inserted into the receiving part 2 line.
- a sleeve-like connecting part 8 is formed on the coupling body 1 on the receiving part 2 opposite side of the angle section 5, which opens on the one hand with a cylindrical mouth portion 9 in the fluid line cavity 7 and on the other by the fluid line tion cavity 7 pointing away outside is open.
- the connecting part 8 has an abutment step 10, which extends at right angles to the longitudinal axis of the connecting part 8 from the mouth section 9 radially outward. From the contact stage 10 extends from the mouth portion 9 pioneering axially outwardly a cylindrical socket portion 11, at the end in the longitudinal direction of the connecting part 8 extending and resilient in the radial direction spring arms 12 are attached.
- the fluid line coupling according to the invention is equipped with a heating element 14, which is made of a, for example, by the addition of carbon particles or metal particles electrically conductive plastic material having a positive temperature coefficient.
- the heating element 14 is inserted in the representation of FIG. 1 in the connecting part 8 and has a front-side first cylinder portion 15 which is arranged flush in the mouth portion 9 and with a receiving part 2 facing front side flat fluid contact surface 16 as a large-area thermodynamic contact area in the area of the angle section 5 forms a wall region of the fluid line cavity 7.
- the heating element 14 has a second cylinder section 17 attached to the side of the first cylinder section 15 facing away from the fluid contact surface 16, which has a larger diameter than the first cylinder section 15, so that between the first cylinder section 15 and the second cylinder section 17 one of the Investment level 10 opposite An horrin 18 is formed.
- the second cylinder portion 17 is flush inserted into the socket portion 11 and is connected to a perpendicular to the longitudinal axis of the connecting part 8 aligned pressure side 19 axially over the spring arms 12 to the outside Ü over.
- two connecting pins 20 are embedded in metal in this embodiment, which extend from the first cylinder portion 15 through the second cylinder portion 17 through the pressure side 19 protruding outward.
- the connecting pins 20 are connected to an electrical power supply, not shown in FIG. 1, with the pins 20, an electric current can be fed to a due to the positive temperature coefficient of the heating element 14 to the Amperage directly proportional heating of the heating element 14 to perform.
- annularly closed sealing ring 21 made of a soft elastic material surrounding the first cylinder portion 15 of the heating element 14 and with its outside on the inner wall of the socket section 11 is applied, wherein the sealing ring 21 is biased in this arrangement in the radial direction.
- the fluid line coupling according to the invention has securing means with a retaining ring 22 made of a heartelasti- see plastic material which surrounds the connecting part 8 on the outside in an assembled arrangement of the fluid line coupling.
- the locking ring 22 is provided on its side facing the receiving part 2 in its assembled arrangement with a locking collar 23 which extends radially inwardly and engages behind the locking lugs 13 in the assembled arrangement according to FIG. 1, so that the securing ring 22 against an axial Moving away from the coupling body 1 is secured away.
- the securing ring 22 has on its side opposite the catch collar 23 a pressure collar 24, which likewise extends radially inward and rests externally on the pressure side 19 of the heating element 14 in an assembled arrangement of the fluid line coupling in this embodiment.
- the dimensions of the heating element 14 and the securing ring 22 are adapted to one another in the longitudinal direction so that the heating element 14 is pressed against the sealing ring 22 with a certain axial pressure force in the assembled arrangement of the fluid line coupling.
- an axial pressure force is exerted on the sealing ring 21, which substantially increases the sealing effect.
- the heating element 14 with increasing heating has a lower mechanical strength, but obtained by the circlip 22 caused by the continuous axial contact pressure of the sealing ring 21 against the contact stage 10 and against the An horrin 18, the high sealing effect substantially remains.
- the heating element 14 is designed to form a thermodynamic contact region with a hollow-cylinder-like fluid contact sleeve 25, which is integrally formed on the side of the first cylinder section 15 facing away from the second cylinder section 17.
- the fluid contact sleeve 25 is located in the region of the angular section 5 on the inner wall of the fluid line cavity 7, so that the radially inwardly facing inner wall 26 of the fluid contact sleeve 25 as an inner wall together with a flat end wall 27 extending between the fluid contact sleeve 25 and at the Fluid line cavity 7 facing the end of the first cylinder portion 15 is formed to form the entire very large-area thermodynamic contact area.
- the fluid contact sleeve 25 is pierced in the connection region of the connection piece 6 to the angle section 5 by a für Bachsaus principleung 28.
- Si chergesch formed on the coupling body 1 and the heating element 14 alignment is Si chergesch that the für Bachsaus Principleung 28 is disposed in the connection region of the connecting piece 6 when the locking ring 22 engages behind the locking lugs 13.
- Fig. 3 shows in a sectional detail view another embodiment of a fluid line coupling according to the invention in the region of the connecting part 8, wherein in the embodiments according to FIG. 1, Fig. 2 and Fig. 3 corresponding elements provided with the same reference numerals and further ren are not explained in detail.
- a thermodynamic contact area of the heating element 14 is provided by a solid cylinder-like fluid contact mandrel 29 arranged centrally at a distance from the inside of the fluid line cavity 7 by an end face of the first cylinder section 15 facing the receiving part 2 and by a fluid contact mandrel 29 outside surrounding flat fluid contact edge surface 30 is formed.
- a very large contact area is also formed.
- the securing ring 22 is attached to the connecting part 8 via a welded connection 31, deviating from the preceding embodiments explained.
- an intermediate member 32 is arranged in the form of a flat plate, which is made of a thermally poorly conductive, hard elastic plastic material to the heating element 14 of the locking ring 22nd thermally isolate and thereby ensure the durability of the axial preload even over very long periods of time with numerous heating cycles.
