Abstract
Description
- The present invention relates to a coupling unit for connecting a fluid line to another fluid line or a fluid connection.
- In many different application forms, fluid conducting lines, thus fluid lines with other fluid lines or with connections which run to a fluid source or a fluid sink, have to be connected in a communicating manner. For this, various connecting techniques, in particular coupling units, are known. In certain applications, little installation space is available for establishing or detaching such a connection. Furthermore, for a series production it can be desired to keep the assembly of the connection as simple as possible. In particular for motor vehicles it can be required to connect gas-conducting lines in an engine compartment with other gas-conducting lines or with adequate connections.
- The present invention is concerned with the problem to provide for a coupling unit of the above mentioned type, an improved embodiment which is in particular characterized in that coupling for establishing the connection can be implemented in a particularly simple manner even in confined space conditions wherein, in particular, a secured connection is to be implemented. Furthermore, an inexpensive producibility of the coupling unit is desired.
- According to the invention, this problem is solved by the subject matter of the independent claim. Advantageous embodiments are subject matter of the dependent claims.
- The invention is based on the general idea to equip the coupling unit with a casing, at least one tubular section, and at least one detent ring arranged between casing and tubular section, wherein these components are designed and adapted to one another in such a manner that, in a first rotational position, the tubular section can be axially inserted for coupling purposes into the casing and is secured in the inserted state by means of the detent ring against axial withdrawal, wherein the tubular section is released in a second rotational position and can be axially withdrawn from the casing. In other words, the connection is established by axially inserting the tubular section into the casing without the need of a rotational movement. At the same time, an axial locking against withdrawal of the tubular section from the casing is achieved which takes place through interaction between casing, tubular section and detent ring. This locking against withdrawal can be released or unlocked by rotating of casing and tubular section relative to one another so that the tubular section can be withdrawn again from the casing without any problems.
- Within a series assembly, for example of vehicles, thus, lines can be connected to one another or to connections by means of said coupling unit simply by insertion. This can be implemented comparatively quickly even in very confined and/or barely accessible assembly situations. For this purpose, the tubular section is arranged, for example, at a fluid line while the casing is arranged at another fluid line or a fluid connection.
- In a particularly advantageous embodiment, the coupling unit can comprise two tubular sections and two detent rings which interact with a common casing. Here, the one tubular section can be inserted on the one side into the casing and can be secured with the detent ring, while the other tubular section can be inserted on the other side into the casing and can be secured with the other detent ring. For example, in this manner, two fluid lines can each be provided with one such tubular section and can each be fluidically coupled via the casing by axial insertion, thus without rotational movement. For decoupling said connection, the casing has only to be rotated relative to the two tubular sections until both tubular sections are unlocked so that it is possible again to axially withdraw them from the casing. In this manner, also such lines can easily be connected to one another and separated from one another which can not be rotated or only against high resistance.
- Further important features and advantages arise from the sub-claims, from the drawings, and from the associated description of the figures based on the drawings.
- It is to be understood that the above mentioned features and the features yet to be explained hereinafter can be used not only in the respectively mentioned combination but also in other combinations or alone without departing from the scope of the present invention.
- Preferred exemplary embodiments of the invention are illustrated in the drawings and are explained in the following description in more detail, wherein identical reference numbers refer to identical, or similar, or functionally identical components.
- In the figures, schematically,
-
FIG. 1 shows a greatly simplified longitudinal section through a coupling unit, -
FIG. 2 shows a longitudinal section as inFIG. 1 but for a different embodiment, -
FIG. 3 shows a perspective view on a casing of the coupling unit, -
FIG. 4 shows a perspective view with tubular sections inserted into the casing, -
FIG. 5 shows a perspective view of a tubular section. - According to
FIGS. 1 and 2 , acoupling unit 1 comprises at least atubular section 2, acasing 3, and at least adetent ring 4. In the shown embodiments, thecoupling unit 1 has twotubular sections 2 and twodetent rings 4 which interact with acommon casing 3. In another embodiment, thecoupling unit 1 can be configured in such a manner that thecasing 3 has only one singletubular section 2 and only one singledetent ring 4. This simple variant, for example, can be mirrored at a plane which runs perpendicular to alongitudinal center axis 5 of the coupling unit to implement the double variant shown here. Also, configurations having more than twotubular sections 2 and more than twodetent rings 4 are principally also conceivable; for example, thecasing 3 can be configured as Y-shaped housing with three connecting points, or as X-shaped housing with four connecting points, or as star-shaped housing with even more connecting points. - The
coupling unit 1 serves for connecting a line, which is not shown here and which conducts a fluid, in particular a gas or a liquid, thus a fluid line, to another fluid line or to a fluid connection by means of which the respective fluid line is connectable, e.g., to a fluid source or a fluid sink. The respective fluid line or the respective fluid connection is not illustrated here. The respective fluid line is fixedly connected in a suitable manner to the respectivetubular section 2. Also, the respectivetubular section 2 can form an end section integrally formed at the respective fluid line. Also, thecasing 3 can be fixedly connected to the respective fluid line or can form an end section integrally formed thereon. The same applies to the potentially existing fluid connection which is fixedly connected either to thecasing 3 or the respectivetubular section 2 or is equipped therewith in an integral manner. - The respective
tubular section 2 has a cylindricalouter contour 6. Thecasing 3 has a cylindricalinner contour 7 which is designed complementary to the respectiveouter contour 6 in such a manner that the respectivetubular section 2 can be inserted axially into thecasing 3. Except for a certain radial play, theinner contour 7 corresponds substantially to the respectiveouter contour 6. In the shown examples, the cross-sections of the twotubular sections 2 are selected such that they are of the same size. It is clear that for another embodiment, differently dimensioned cross-sections for theouter contours 6 of the twotubular sections 2 can principally also be implemented. In this case, thecasing 3 has, e.g., aninner contour 7 which has different cross-sections at two axial sections. Further, in the shown examples, theouter contour 6 of the respectivetubular section 2 is substantially equipped with a constant cross-section in axial direction. In another embodiment, a cross-sectional profile in axial direction with a single step or multiple steps is also conceivable for the respectiveouter contour 6. In this case, theinner contour 7 or the respective section of theinner contour 7 is then shaped correspondingly. - The respective
detent ring 4 is arranged radially betweencasing 3 and the respectivetubular section 2 once the respectivetubular section 2 is axially inserted into thecasing 3. The radial direction is designated in theFIGS. 1 and 2 by anarrow 8 while the axial direction is designated with anarrow 9. - The
casing 3, the respectivedetent ring 4 and the respectivetubular section 2 are configured and adapted to one another in such a manner that, in a first relative rotational position oftubular section 2 andcasing 3, thetubular section 2 can be axially inserted for coupling purposes into thecasing 3, namely far enough that the respectivetubular section 2 is latched via the associateddetent ring 4 with thecasing 3. Through this latching, the respectivetubular section 2 is secured in the first rotational position by the respectivedetent ring 4 in thecasing 3 against axial withdrawal. It is remarkable that for coupling, thus for establishing the fluidic connection betweencasing 3 andtubular section 2, no rotational movement about thelongitudinal center axis 5 betweencasing 3 andtubular section 2 has to be carried out. Furthermore, thecasing 3, the respectivetubular section 2 and the respectivedetent ring 4 are adapted to one another or configured in such a manner that, in the inserted state, thecasing 3 and the respectivetubular section 2 can be rotated relative to one another about thelongitudinal center axis 5 in such a manner that a second relative rotational position of thecasing 3 and the respectivetubular section 2 can be set which differs from the first rotational position and in which it is possible to axially withdraw the respectivetubular section 2 from thecasing 3. In this manner, the fluidic connection betweencasing 3 andtubular section 2 can thus be decoupled. By means of the rotation betweencasing 3 andtubular section 2, the latching or securing generated by means of the detent ring can be released to allow the axial withdrawal of thetubular section 2. - The respective
detent ring 4 is advantageously inserted into aring groove 10 which is radially open. In the shown examples, therespective ring groove 10 is formed on theinner contour 7 of thecasing 3. In another embodiment, thering groove 10 can also be formed on theouter side 6 of the respectivetubular section 2. Thedetent ring 4 inserted into therespective ring groove 10 is axially supported on agroove wall 11 which axially delimits thering groove 10. Hereby, an intensive force transmission betweendetent ring 4 and therespective groove wall 11 can be achieved. - In the embodiments shown here, the respective
detent ring 4 has a plurality ofdetent elements 12 which, according toFIG. 3 , are arranged adjacent to one another in circumferential direction. Thedetent elements 12 are arranged radially on therespective detent ring 4 in a spring-elastically resilient manner. Furthermore, they are dimensioned in such a manner that they project or protrude radially from therespective ring groove 10. In the inserted state of the respectivetubular section 2 and in the first rotational position betweencasing 3 and the respectivetubular section 2, each of thedetent segments 12 engage with adetent contour 13 and is supported thereon inaxial direction 9. Here too, an intensive force transmission between therespective detent ring 4 and the associateddetent contour 13 can be implemented. In the shown examples, therespective detent contour 13 is formed on theouter side 6 of the respectivetubular section 2. Also conceivable is an embodiment in which therespective detent contour 13 is formed on theinner side 7 of thecasing 3. - In order to be able to withdraw the respective
tubular section 2 again from thecasing 3, thedetent segments 12 have to be moved out of thedetent contours 13. For this purpose,suitable reset contours 14 are provided which, for example, can be formed according toFIG. 5 on the respectivetubular section 2. Alternatively, thereset contours 14 can also be provided on thecasing 3. However, here, they are arranged on the component that also comprises thedetent contours 13. Advantageously, saidreset contours 14 are on the same axial height as thedetent contours 13, thus in the same axial section, wherein in each case onereset contour 14 is located in circumferential direction between twoadjacent detent contours 13. Hereby, in the inserted state, thereset contours 14 are positioned in the first rotational position also in circumferential direction between twoadjacent detent segments 12 of thedetent ring 4. By rotating thecasing 3 andtubular section 2, thereset contours 14 force or push thedetent elements 12 into thering groove 10. Thereset contours 14 are dimensioned in such a manner that they push thedetent segments 12 far enough into thering groove 10 that they are released from therespective detent contour 13 or get out of it. To simplify the transition from the first rotational position into the second rotational position, thereset contours 14 can comprise insertion chamfers or ramps in circumferential direction. Additionally or alternatively, also thedetent segments 12 can be provided in circumferential direction with insertion chamfers or ramps which facilitate a sliding in or sliding under of thereset contours 14 underneath thedetent segments 12. - As soon as the second rotational position is reached by rotating
casing 3 andtubular section 2, thereset contours 14 push thedetent segments 12 far enough into thering groove 10 or out of thedetent contours 13 that thetubular section 2 is released and can be axially withdrawn from thecasing 3. - According to
FIG. 3 , according to a preferred embodiment, therespective detent ring 4 can comprise a plurality ofsupport segments 15 which are arranged on the detent ring's 4 side facing axially away from thedetent segments 12 and which are adjacent to one another in the circumferential direction. Thesupport elements 15 are axially supported within thering groove 10 by thegroove wall 11. In circumferential direction, thedetent ring 4 has, at least between twoadjacent detent elements 12, in each case onerecess 16, respectively. Within thering groove 10,projections 17 can be provided which each engage axially and radially with such arecess 16. Here, therespective projection 17 projects, for example, from agroove wall 18 which delimits thering groove 10 in axial direction. - Through the engagement of the
projections 17 with therecesses 16, a protection against rotation of thedetent ring 4 relative to thering groove 10 is generated, thus relative to thecasing 3. Also, in a corresponding manner, oneaxial recess 19 can be provided in circumferential direction in each case at least between twoadjacent support segments 15. Principally, on thegroove wall 11 which axially supports thesupport segments 15, non-shown projections which engage with therecesses 19 can be provided to secure thedetent ring 4 against rotation within thering groove 10. Furthermore, therecesses 16 generate an increased spring elasticity between thedetent segments 12, and therecesses 19 generate an increased spring elasticity between thesupport segments 15 within thedetent ring 4. Said spring elasticity allows or promotes the assembly of thedetent ring 4 and promotes the spring elasticity or the radial resilience of thedetent segments 12. - According to the
FIGS. 1 to 3 , thecoupling unit 1 can additionally be equipped with at least oneseal 20 which is ring-shaped and acts in radial direction. In the example, twosuch seals 20 are provided which each are assigned to one of thetubular sections 2. In the embodiment shown inFIG. 1 , theseals 20 are positioned before therespective detent ring 4 with respect to aninsertion direction 23 indicated with an arrow. In the embodiment shown inFIG. 2 , theseals 20 are behind therespective detent ring 4 with respect to theinsertion direction 23. For fixation of theseals 20 on the respectivetubular section 2 and on thecasing 3, thecasing 3 as well as the respectivetubular section 2 can be equipped with adequate receivinggrooves respective seals 20 immerges. - According to
FIG. 4 , thecasing 3 and the respectivetubular section 2 can be equipped withmarkers identifiable markers casing 3 and the respectivetubular section 2, respectively, and are, for example, configured as ribs extending in longitudinal oraxial direction 9. They are—as illustrated in FIG. 4—oriented in alignment to one another if thecasing 3 and the respectivetubular section 2 are both in the first relative rotational position. - The respective fluid line can involve a pipe line or a hose line. The respective
tubular section 2 and/or therespective detent ring 4 and/or thecasing 3 can be made of metal or plastic.
