Description

The present invention relates to a connection device for providing a media connection on a component with a fluid channel. Furthermore, the invention relates to an arrangement of a connection device and a component with a fluid channel.

Connection pieces on components with an integrated media channel, for example a cooling channel, are usually sealed by means of an axial seal or a radial seal. Both options take up a lot of space. The axial seal requires this in order to be able to provide the sealing point. The radial seal usually requires an insertion chamfer on the component to protect the seal from damage during the insertion process.

In order to provide a media connection on a component with a fluid channel, different solutions are known from the prior art. For example, from the U.S. 7,857,359 B2 a quick-release coupling for connecting a feed or pressure line to a wall of a collector of a heat exchanger is known. The coupling has a first coupling part and a second coupling part which are dimensioned in such a way that they engage with one another. A sealing device is positioned between the first coupling part and the second coupling part.

From the US 6,481,759 B1 a connection structure is known for connecting tubular elements through which a liquid, for example fuel, flows.

From the U.S. 2,870,794 A a connecting device is known which has the features of the preamble of patent claims 1 to 3. Furthermore, from the U.S. 2,870,794 A an arrangement is known which has the features of the preamble of patent claim 9.

The EP 2 610 947 A2 , the DE 10 2018 222 279 A1 and the DE 10 2010 007 975 A1 disclose further prior art.

The object of the present invention is to create a connection device that can be attached to a component in a particularly simple and wear-free manner for the purpose of providing a media connection for a fluid channel of this component. Furthermore, the object of the invention is to specify an arrangement of a connection device on a component with a fluid channel.

These problems are solved by the subject matter of the independent patent claims.

The connection device is used to provide a media connection on a component with a fluid channel. This media connection can be, for example, a nipple, a screw connection, a plug connection or a coupling piece. The media connection can be used in particular to connect a flexible tube to the media connection for the purpose of establishing a fluid connection between the fluid channel and the tube. In this respect, the connection device serves to enable a fluid connection between the fluid channel and a further component, for example a supply line or discharge line, in particular in the form of a hose. The connection device serves to be connected to the component in order to supply a medium to the fluid channel or to remove medium located in the fluid channel by means of the media connection. The connecting device has a bearing body and a central body which is mounted in the bearing body so that it can be displaced, preferably in the axial direction, between a loose position and a sealed position. The central body has a fluid channel, which serves to conduct the medium through for the purpose of introducing the medium into the fluid channel of the component and/or discharging medium from the fluid channel of the component. The central body has an insertion section which protrudes in relation to the bearing body, preferably in the axial direction, for the purpose of inserting the central body into the fluid channel of the component. The insertion section has a collar section, with an elastically deformable sealing element being arranged between the collar section and the bearing body. A distance between the collar section of the insertion section and the bearing body is smaller in the sealing position than a distance between the collar section of the insertion section and the bearing body in the loose position. Furthermore, the connecting device has a locking means that can be transferred from an open position to a locking position, the locking means in the locking position interacting with the central body and the bearing body in such a way that the central body is prevented from being displaced from the sealed position into the loose position.

This design has the advantage that in the loose position the central body can be inserted very easily into the fluid channel of the component, since the elastically deformable sealing element is not deformed or is only slightly deformed due to the greater distance between the collar section of the insertion section and the bearing body in the loose position. so that the sealing element in the loose position does not, or at least does not, come into contact with a wall of the component that delimits the fluid channel friction between the wall and the sealing element is low, so that the insertion section can be inserted into the fluid channel with little effort. The connecting device is preferably inserted into the component until the bearing body comes to rest against the wall of the component in the axial direction. After insertion, the central body is shifted from the loose position to the sealing position relative to the bearing body, which reduces the distance between the collar section of the insertion section and the bearing body, as a result of which the elastically deformable sealing element is braced and pressed on the inside against the channel wall delimiting the fluid channel. This ensures the sealing effect of the connecting device. Subsequent to the displacement or during the displacement, the locking means is transferred from the open position, in which the central body can be displaced between the sealed position and the release position, into the locked position. In the locking position, when the central body is in the sealing position, the locking means prevents the central body from being displaced relative to the bearing body in the direction of the loose position, as a result of which the sealing element is held in the braced position in which the sealing element is pressed against the duct wall. The connection device is removed from the fluid channel in the reverse order. The locking means must first be transferred from the locking position to the open position and then or during this time the central body must be shifted from the sealed position to the loose position relative to the bearing body, as a result of which the distance between the collar section of the insertion section and the bearing body increases. Accordingly, the sealing element changes from the clamped state, in which it contacts the channel wall, to the unclamped state, in which it does not contact the channel wall without at least less pressure.

The design described above has the advantage that an insertion chamfer or insertion bevel on the component can be omitted and the required installation space is thus reduced. This saves space and material. Installation space, weight and costs can be reduced by eliminating an insertion bevel and the associated machining or by eliminating an axial sealing surface and the associated machining of the components. In addition, the assembly effort is reduced, since the assembly can be carried out particularly easily. In addition, only the connecting device and the component have to be handled during assembly. In addition, damage during the assembly process is avoided, since the sealing element does not or at least hardly interacts mechanically with the component during the process of being inserted into the fluid channel. In addition, assembly can take place without tools, since the seal or the insertion section can be inserted into the fluid channel preferably without force or essentially without force.

It is considered to be particularly advantageous if the collar section protrudes in the radial direction in relation to the sealing element in the loose position. As a result, the collar particularly effectively protects the sealing element from damage during the process of inserting the insertion section into the fluid channel of the component.

The sealing element is preferably a sealing ring.

It is considered particularly advantageous if the central body has a connection section, the connection section protruding from the bearing body on a side of the bearing body facing away from the insertion section, the connection section having the media enclosure. In this respect it is provided that the central body passes through the bearing body.

It is quite conceivable that the central body is angled, for example angled by 45° or 90°. However, the central body is preferably straight.

It is considered particularly advantageous if the connection section has a further collar section, with the locking means being arranged between the bearing body and the further collar section and interacting with the further collar section. Such a design is the subject matter of patent claim 1. The further collar section preferably engages behind the locking means in the locking position on a side facing away from the insertion section.

It is considered particularly advantageous if the locking means can be displaced perpendicularly to the insertion direction of the insertion section, in particular perpendicularly to the axial direction, from the open position to the locking position and vice versa. Such a design is the subject of patent claim 2.

Furthermore, it is considered particularly advantageous if the locking means can be transferred from the locked position to the open position. This allows the connection device to be easily detached from the component.

The locking means can preferably be actuated manually. Under manually is presently understood that the use of a tool to transfer the locking means from the Open position in the locked position is not necessary.

It is considered to be particularly advantageous if the locking means interacts with the bearing body and/or the central body during the transfer of the locking means from the open position into the locking position in such a way that the central body is displaced from the loose position into the sealed position, and the distance between the collar section changes accordingly of the insertion section and the bearing body when transferring the locking means from the open position to the locking position.

In this respect, the locking means not only serves to lock the connecting device in the sealed position, but also to move the central body from the loose position into the sealed position. This makes handling easier, since only the locking means has to be actuated.

It is considered to be particularly advantageous if a restoring force of the sealing element in the sealing position is sufficiently great to move the central body relative to the bearing body into the loose position when the locking means is transferred from the locking position to the open position. As a result, no separate displacement of the central body of the central body from the sealed position into the loose position is necessary, for example in order to remove the connection device from the component. This makes handling easier.

It is considered advantageous if the locking means has a guide contour and the bearing body and/or the central body has a counter-contour that interacts with the guide contour for moving the central body from the release position in the direction of the sealed position when the locking means is transferred from the open position to the locked position. The guiding contour and/or the counter-contour is preferably an inclined surface or inclined edge. Such a design is the subject of patent claim 3.

It is considered to be particularly advantageous if the collar of the insertion section and/or the further collar is designed as a surrounding collar.

In order to secure the connecting device against falling out of the component, it is considered to be particularly advantageous if the locking means has a holding structure, with this holding structure being in engagement with a counter-structure formed on the component in the locking position, preferably in a counter-structure formed as a recess of the component is inserted. It is therefore not necessary to provide an additional component for the purpose of securing the connection device against falling out. Due to the fact that the holding structure is formed on the locking means, no further work step is required either, since the holding structure and the counter-structure are also engaged when the locking means is in the locking position. The two aforementioned structures thus prevent the connecting device from falling out or moving out when pressure is applied to the fluid channel or vibration of the component when the locking means is in the locking position.

The arrangement according to the invention is the subject of patent claim 9 and relates to an arrangement of a connection device for providing a media connection on a component and a component with a fluid channel, the connection device having a bearing body and a central body which is movably mounted in the bearing body between a loose position and a sealed position, wherein the central body has a fluid channel and has an insertion section protruding in relation to the bearing body for insertion into the fluid channel of the component, the insertion section having a collar section, an elastically deformable sealing element being arranged between the collar section and the bearing body, with a distance between the collar section and the insertion section and the bearing body in the sealing position is smaller than a distance between the collar section of the insertion section and the bearing body in the loose position, the connection devices g has a locking means that can be transferred from an open position to a locking position, the locking means in the locking position interacting with the central body and the bearing body in such a way that the central body is prevented from being displaced from the sealed position into the loose position, with the insertion section being arranged in the fluid channel of the component is, wherein the bearing body is in contact with the component, wherein the central body is in the sealing position and the locking means is in the locking state and wherein the sealing element is deformed in such a way due to the reduced distance between the collar of the insertion section and the bearing body compared to the loose position, that the sealing element is pressed on the inside against a wall delimiting the fluid channel, characterized in that the component has a counter-structure, wherein in the locking position the locking means and the counter-structure engage ff are and in the open position the locking means and the counter-structure are disengaged. This prevents the connection device from falling out of the fluid channel secured. The counter-structure can be designed as a recess, for example. The counter-structure preferably engages behind the locking means on a side facing away from the fluid channel.

With regard to the arrangement, it is also considered to be particularly advantageous if the insertion section and/or the component is/are free of an insertion chamfer in the region of the fluid channel.

It is quite conceivable that the counter-structure of the component also serves to fix the connection device with regard to the axial positioning of the connection device to the component. It is also entirely conceivable that when the locking means is transferred from the open position to the locking position, the locking means interacts with the counter-structure in such a way that a force acting in the direction of the component is exerted on the bearing body. For this purpose, the counter-structure and/or the locking means can have a preferably inclined guide surface.

The locking means preferably also serves as a visual indicator of whether the locking means is in the locked position or in the open position. It is quite conceivable that the locking means has a display surface, with this display surface being visible from the outside in the open position and not being visible from the outside in the locking position, for example being covered by a section of the connecting device and/or the component.

The invention is explained in more detail in the following figures using an exemplary embodiment, without being restricted thereto. Show it:

• 1 an embodiment of a connection device in a sectional view,
• 2 a component with a fluid channel in a perspective view,
• 3 according to an arrangement of the connection device 1 in a component with a fluid channel, in a sectional view.

The 1 shows a connection device 1 for providing a media connection 2 on a component 3, this component 3 having a fluid channel 4. The connecting device 1 has a bearing body 5 and a central body 6 which is mounted in the bearing body 5 so that it can be displaced in the X-direction between a loose position and a sealed position, the central body 6 passing through the bearing body 5 in the present case. The central body 6 has a fluid channel 7 and a section 8 which protrudes in the axial direction X relative to the bearing body 5 and can be inserted into the fluid channel 4 of the component 3 . The central body 6 also has a connection section 12 , the connection section 12 protruding from the bearing body 5 on a side of the bearing body 5 facing away from the insertion section 8 , the connection section 12 having the media connection 2 . The media connection can be designed as a thread or nipple, for example.

The insertion section 8 has a collar section 9 , an elastically deformable sealing element 10 being arranged between the collar section 9 and the bearing body 5 . Because the central body 6 can be moved relative to the bearing body 5, a distance between the collar section 9 and the bearing body 5 can be changed, with a distance A2 between the collar section 9 of the insertion section 8 and the bearing body 5 being smaller in the sealing position than a distance A1 between the Collar portion 9 of the insertion portion 8 and the bearing body 5 in the loose position. Depending on the distance A1, A2 between the collar section 9 of the insertion section 8 and the bearing body 5, the elastically deformable sealing element 10 is compressed to a greater or lesser extent in the axial direction X, as a result of which the elastically deformable sealing element 10 can be changed in its radial expansion. In the in the 1 shown state is the center body 6 in the release position. In the in the 3 shown state is the central body 6, however, in the sealing position. In the in the 1 In the state shown, the sealing element 10 is not braced and does not protrude in the radial direction relative to the collar section 9 . In the loose position, the insertion section 8 can therefore be inserted particularly easily into the fluid channel 4 of the component 3 since the sealing element 10 is not compressed in its axial extent and accordingly does not protrude in the radial direction in relation to the collar 9 . In this state, during the insertion process, the sealing element does not come into contact with a wall 15 that delimits the fluid channel 4 of the component 3 . In order to achieve a sealing effect of the sealing element 10 when the insertion section 8 is arranged in the fluid channel 4, the central body 6 is displaced relative to the bearing body 5 after the insertion from the loose position into the sealing position, in which the sealing element 10 is deformed in this way due to the reduction in the distance that the sealing element 10 is pressed on the inside against a wall 16 delimiting the fluid channel 4 . This tense state shows the 3 .

Since the distance between the collar portion 9 and the bearing body 5 is reduced against a restoring force of the sealing element 10, it is necessary to compress the bearing body 5 and the central body 6 in the sealing position in which the sealing element 10 is compressed in the axial direction X is mized and rests against the wall 16 against being pushed back into the loose position in which the sealing element is in the unstressed state. For this purpose, the connecting device 1 has a locking means 11 that can be transferred from an open position to a locking position, with the locking means 11 in the locking position interacting with the central body 6 and the bearing body 5 in such a way that the central body 6 and the bearing body 5 can be displaced from the sealed position is prevented in the loose position, whereas in the open position a displacement of the central body 6 and the bearing body 5 to each other is possible. In the present case, the locking means 11 is a locking element, the locking element being displaceable perpendicular to the direction of insertion X. The connection section 12 has a further collar section 13 , the locking means 11 being arranged between the bearing body 5 and the further collar section 13 and interacting with the further collar section 13 . In the present case, the locking means 11 has a wedge-shaped section, this wedge-shaped section forming a guide contour 14, this guide contour 14 interacting with a counter-contour 15, which is formed here by the further collar section 13, when the locking means 11 is moved from the open position into the locking position . Like that one in particular 1 As can be seen, a transfer of the locking means 11 from the open position to the locked position, which takes place perpendicularly to the axial direction X in the present case, results in the guide contour 14 and the counter-contour 15 interacting in such a way that when transferring from the open position to the locked position the locking means 11 is supported on the bearing body 5 in the axial direction X and moves the central body 6 counter to the X direction with respect to the bearing body 5 in such a way that the distance between the collar section 9 and the bearing body 5 is reduced and the distance is correspondingly increased between the collar portion 13 and the bearing body 5 comes. Thus, when the locking means 11 is transferred from the open position to the locking position, the central body 6 is transferred from the release position to the sealed position. In the locking position, a blocking section, which is rectangular in cross section and adjoins the guide contour 14, is arranged between the bearing body 5 and the collar section 13, on which the bearing body 5 and the collar section 13 rest on opposite sides.

Again 3 As can be seen, the component 3 has a counter-structure 17 in the form of a recess, with the locking means 11 and the counter-structure 17 being engaged in the locking position, as a result of which the component 3 and the connecting device 1 are locked in the axial position relative to one another and the connecting device accordingly 1 is secured against falling out of the component 3. Thus, in the locking position, the connecting device 1 is not only held in the component 3 in a force-fitting manner by means of the tensioned sealing element 10 , but is also held in the component 3 in a form-fitting manner. In the open position of the locking means 11, on the other hand, the locking means 11 and the counter-structure 17 are disengaged, so that the connecting device 1 can be removed from the component 3 in the open position, namely can be pulled out.

Like in particular a comparison of 1 and 3 can be seen, the locking means 11 can also serve as a visual indicator of whether the locking means 11 is in the locked position or in the open position. It is quite conceivable that the locking means 11 has a display surface, this display surface being visible from the outside in the open position and not being visible from the outside in the locking position, for example being covered by the additional collar 13 .
