A plug coupling with two pluggable tubular coupling parts (1, 2) for connecting two components carrying a fluid has a first annular groove (13) in an insertion section (14) of one coupling part (2) and in a receiving section (6) of the other coupling part (1 ) two diametrically opposite slots (12) and an approximately U-shaped elastic bracket (3). Its legs (15) protrude through the slots (12) and snap into the first annular groove (13) when the coupling parts (1, 2) are plugged together. The plug coupling also has a sealing ring (4) between the plugged coupling parts (1, 2) and a locking ring (5), which together with the one coupling part (1) and a shoulder (31) of this coupling part (1) has a sealing ring (4 ) receiving second annular groove (32) limited. In order to ensure that the plug-in area of the receiving and inserting section (6, 14) is as short as possible axially, the receiving section (6) has a radially outer peripheral wall (10) and a radially inner peripheral wall (11), the inner peripheral wall (11 ) on its radially outer peripheral side, the second annular groove (32) has at least almost in the same radial plane as the first annular groove (13).
The invention relates to a plug-in coupling two pluggable tubular coupling parts for connecting two components carrying a fluid, at which is an insertion section of a coupling part first ring groove and a receiving portion of the other Coupling part two diametrically opposite Slots and an approximately U-shaped elastic bracket has gel, whose legs protrude through the slots and when plugging the coupling parts into which he engage ring groove; with a sealing ring between the put together coupling parts and with a siche ring, which together with the other coupling part and a shoulder of this coupling part one you tring receiving second ring groove limited.
In a known plug-in coupling of this type (EP 0 392 234 A2) the sealing ring and the locking ring are on the inside of an outer peripheral wall of the receiving portion a coupling part angled by 94 ° axially behind the implementation of the bracket slots arranged. The receiving section is therefore relatively long, so that it is sufficient radial support of the insertion section together coupled state guaranteed against angling. In contrast, the length of the receiving section is narrow installation conditions such as those in the engine compartment Motor vehicle are present, often too large. In the uncoupling state is the outside, which acts as a sealing surface side of the insertion section is free. It can therefore easily due to mechanical influences, for example with a Transport, be damaged. The consequence could be an Un tightness of the connection.
DE 27 17 973 C2 is a plug-in coupling with two pluggable tubular coupling parts for Connect a fluid leading components known in the an insertion section of a coupling part Ring groove and a receiving section of the other dome lung part two diametrically opposite Slots and an approximately U-shaped elastic bracket has gel, whose legs protrude through the slots and when plugging the coupling parts into the Snap the ring groove into place. The receiving section has a radi al outer peripheral wall and a radially inner circumference wall, between which the insertion section can be inserted is. The plug-in coupling also contains a sealing ring for mutual sealing of the mated Coupling parts. The sealing ring is on a tube that the one of the two to be connected, carry a fluid the components forms between a truncated cone Head or bead at one end of the tube and a ra dialen end face of the inner peripheral wall arranged. With this arrangement, the sealing ring and the Receiving section having second coupling part before being mounted on the pipe to the coupling parts to be able to put together. This pre-assembly is at ei a relatively long pipe or a pipe in the form a pipe socket, the other end of which already has an egg a third component, for example the radiator of a motor vehicle stuff, connected, difficult or not possible, since at least the second coupling part does not overlap let the head or bead of the pipe slide away, because the inner diameter of the inner peripheral wall of the second coupling part to the outer diameter of the raw res is adjusted and the risk of overstretching the Sealing ring would exist.
The invention has for its object a plug Specify coupling of the type mentioned, whose Mating area is shorter, but still sufficient mutual radial support of the insertion section and receiving section against angling and si mutual mutual sealing of the coupling parts ensures.
According to the invention, this object is achieved in that the receiving portion has a radially outer peripheral wall and has a radially inner peripheral wall between which the insertion section is insertable that the second ring groove in the assembled state of the dome parts radially to the inside of the insertion section at least almost in the same radial plane as the first There is an annular groove and that the radially inner peripheral wall the radially outer peripheral side of the second annular groove having.
The fact that the ring grooves at least almost, in the green in the most extreme case, exactly in the same radial plane, it is possible to change the length of the mating area, that is of both the receiving and the inserting section, train shorter than before. Still arises on due to the double wall of the receiving section adequate mutual radial support and guidance tion of the two mated sections against each other mutual radial angling of the two sections, to ensure the tightness of the connection. There furthermore the second ring groove and thus also the sealing ring in the mated (coupled) state of the Coupling parts radially inside the insertion section lies, one of the two sealing surfaces, which with the Seal ring come in contact or come, both in always radial as well as when disengaged protected from the outside inside the insert section and the other sealing surface within the through form the two peripheral walls of the receiving portion ten annular space protected from the outside, so that the danger damage to the sealing surfaces radially from the outside avoided and accordingly the tightness of the Connection is guaranteed more reliable.
The peripheral walls are preferably integral with their Coupling part shaped. This simplifies their manufacture lung.
Furthermore, the coupling parts from high temperature be made of permanent plastic so that it ins especially withstand the high temperatures like them occur in the engine compartment of a motor vehicle.
If the plastic is a linear, semi-crystalline bottom is lyphenylene sulfide, it can reach temperatures up to Withstand 240 ° C, for a short time even up to 270 ° C. Dar moreover, this material has high flame resistance, very good resistance to chemicals and oxidation high hardness and rigidity as well as low Water absorption and even at elevated temperatures only a slight tendency to creep. By adding ver reinforcing fillers such as glass fibers and glass fiber Mineral blends, can add rigidity and strength as well as the heat resistance further increased the.
Then the one coupling part, preferably that the receiving portion having coupling part, on the En de its mating area be angled. This ver not only shortens the axial length of the coupling concerned to save space between two units built in, but also dispenses with the fact that a given if the hose to be attached is on at the other end nem end be made angled or curved must, which is extremely labor intensive, since such Shaping the hose end mostly manually follows.
The invention and its developments will be next Based on the attached drawing one preferred th embodiment described. Show it:
Fig. 1 is a perspective view of a coupling portion on a coupling part of a plug-in coupling according to the invention and
Fig. 2 is a sectional view of a plug-in coupling according to the invention in the assembled state, in which only the plug-in section of the one coupling part is shown.
The illustrated embodiment of a plug-in coupling according to the Invention consists of two tubular plug-in coupling parts for connecting two fluid-carrying components, for example a radiator of a motor vehicle and the cooling water hose, preferably for carrying out the charge air of a turbocharger, furthermore from a retaining bracket 3 , a sealing ring 4 and a locking ring 5 .
The coupling part 1 has a receiving section 6 and, in contrast, at the end of the receiving section 6 angled by approximately 90 ° connecting section 7 , on which a hose by means of a clamp between a stop collar 8 and a retaining rib 9 can be attached.
The receiving section 6 has a radially outer circumferential wall 10 and a radially inner circumferential wall 11 . In the peripheral wall 10 , two diametrically opposed, radially continuous slots 12 are formed which extend over an arc of the peripheral wall 10 . The slots 12 are aligned with an annular groove 13 in the outer circumferential side of an insertion section 14 formed at the end of the coupling part 2 . The approximately U-shaped retaining bracket 3 engages with its legs 15 in the slots 17 . The bracket 3 is made of Stahlfe derdraht and is therefore elastic. The legs 15 lie gene with central portions radially inside the outer circumferential wall 10 and with their leg 15 ver binding crossbar 17 radially outside the circumferential wall 10th The crosspiece 17 extends between two radially outwardly projecting from the peripheral wall 10 and extending in the circumferential direction of parallel pairs of rip pen and protrudes between the pairs of ribs 18 in a shorter central region radially beyond the pairs of ribs 18 . The free ends of the legs 15 are axially bent in opposite directions Endab cut 19 on the outside of the peripheral wall 10 . Only one of the end sections 19 is visible in FIG. 1.
In order to protect operators from injuries, the end sections 19 in the illustrated operating position were in front of one of two axially aligned projections 20 . Furthermore, at the edge of the slots 12 in the outside of the peripheral wall 10 axial grooves 21 with a radial side wall 22 and an oblique side wall 23 are formed. In the grooves 21 , one of the Endab sections 19 can snap into place when the retaining bracket is pulled out radially, in order to prevent inadvertent complete radial removal of the retaining bracket 3 from the slots 12 , the end portions 19 then striking against one of the radial side walls 22 , since the legs 15 are under a radially inward bias.
The insertion section 14 is provided in the insertion direction in front of the annular groove 13 with radially outer oblique or conical ring surfaces (chamfers) 24 and 25 . When plugging together the coupling parts 1 and 2 in the position shown in Fig. 2, the legs 15 of the bracket 3 slide over the inclined surfaces 24 and 25 , then to snap into the annular groove 13 . Because of the inclined surface 25 , an end portion 27 of a plug-in portion 14 has a smaller wall thickness than the rear part 28 , the annular space between the peripheral walls 10 and 11 to behind the slots 12 having a radial width corresponding to the wall thickness of the part 28 then down to the wall thickness of the Endab to reduce the area of the thinner end portion 27 via a step 29 section 27th The end section 27 then protrudes in the assembled state, lying against the circumferential walls 10 and 11 , in the narrower end section of the annular space.
The radially inner circumferential wall 11 of the receiving portion 6 also has a stepped diameter, but on its radially outer side, wherein the securing ring 5 , the thinner end portion 30 of the inner circumferential wall 11 and a shoulder 31 of the circumferential wall 11 define an annular groove 32 , which at least is almost in the same radial plane as the annular groove 13 . As a result, the plug-in area in which the receiving section 6 and the plug-in section 14 overlap can be designed shorter than in the prior art, even if the annular grooves 13 and 32 are not exactly in the same radial plane. Likewise, the double-walled receiving section 6 and the annular space between the circumferential walls 10 and 11 , which receives the plug-in section 14 closely, in connection with the retaining ring 5 , the outer diameter of which is also almost equal to the inner diameter of the plug-in section 14 , prevents radial mutual angular deflection On receiving section 6 and insertion section 14 with radial loading of one or the other coupling part 1 , 2 or both, for example due to vibrations, so that the tightness of the connection even with such a gene by the applied to the insertion section 14 and the inner peripheral wall 11 Sealing ring 4 is further guaranteed. Furthermore, the sealing surfaces 4 coming into contact with the sealing ring 4 of the plug-in section 14 and the peripheral wall 11 are also protected in the coupled state of the coupling parts 1 , 2 against damage from radially outside.
The circlip 5 has a radially inner circumferential flat rib 33 , the section in a matching annular groove 34 on the radially outer side of the end portion 30 by to put together the circlip 5 and receiving section 6 after insertion of the sealing ring 4 .
The coupling part 1 is made together with the peripheral walls 10 and 11 in one piece from a linear, partially crystalline polyphenylene sulfide with a reinforcing filling made of, for example, glass fibers or glass fiber-mineral mixtures and has a very high temperature resistance of up to 240 ° C, for a short time even up to 270 ° C, an inherent flame resistance, a very good chemical and oxidation resistance, a high hardness and rigidity, a very low water absorption and only a low tendency to creep even at elevated temperatures.
The coupling part 2 and the locking ring 5 are made of the same plastic as the coupling part 1 Herge.
The plug-in coupling is therefore particularly suitable for use at high temperatures of the environment and / or through the plug-in coupling passed fluid and also suitable for aggressive fluids.
For decoupling, the bracket 3 is pulled out of the position shown in Fig. 1 by detecting the radially protruding the central portion of the crosspiece 17 so far from the slots 12 until the end portions 19 each in an axial plane between one of the projections 20 and one of the Grooves 21 lie. In this La ge, the central portions of the legs 15 of the bracket 3 are no longer radially on the inside of the outer circumferential wall 10 , that is, they no longer engage in the annular groove 13 , so that the coupling parts 1 and 2 can be pulled apart largely unhindered nen.
Axial, diametrically opposed grooves 35 in the inside of the outer circumferential wall 10 of the hitch be part 1 serve to accommodate accordingly in the form of adapted (not shown) ribs on the outside of the insertion portion 14 to the coupling parts 1 and 2 only in a predetermined relative To be able to put the angle of rotation together.
