Abstract
Description
Technical Field
[0001] The invention relates to a device for coding a first connection partner and a second connection partner of a bayonet and a device assembly. Background Art
[0002] In order to transport fluids between different containers of a device (e.g. a cooling unit), fluid lines are used. In this case, these fluid lines can be connected via fluid line adapters, for example to a distributor plate, which supplies the fluids supplied via the fluid lines to a different and applicable plurality of additional fluid lines. If a large number of fluid lines are used, these lines must not be mixed up in order to obtain the functionality of the device and to prevent damage.
[0003] To this end, the fluid line and the corresponding receiving member of the fluid line can be coded with a mark that associates the fluid line with the receiving member. Therefore, before assembling the fluid line, the user must associate the mark on the fluid line with the corresponding mark on the receiving member of the fluid line.
[0004] It is therefore an object of the present invention to provide an improved apparatus for an encoding pipeline which operates in a more efficient manner. Summary of the invention
[0005] The invention is mainly characterized by claims 1 and 8. Claims 2 to 7 as well as claims 9 and 10 are related to embodiments.
[0006] In a device for coding a first connection fitting and a second connection fitting of a bayonet, wherein the first connection fitting has at least two locking arms for locking the connection, and the first connection fitting is arranged on a fluid line adapter, and wherein the second connection fitting has a flange ring, which is used to guide a plurality of grooves through the first locking fitting, wherein the plurality of grooves corresponds to the number of the locking arms for guiding through the locking arms, and the second connection fitting is arranged on an adapter receiving member, according to the invention, the first locking arm has a different geometry than the other locking arms, wherein the first groove associated with the first locking arm has a compatible geometry for positioning the first connection fitting and the second connection fitting in a predetermined position, and the additional groove has a different geometry that is incompatible with the first locking arm, and wherein the device also has a mechanical coding device, wherein the coding device has a first coding fitting on the first connection fitting and a second coding fitting on the second connection fitting, wherein when the first connection fitting and the second connection fitting are arranged in a predetermined position relative to each other and connected by the bayonet, the first coding fitting and the second coding fitting are oriented in a mutually compatible manner.
[0007] With the device according to the invention, using mechanical coding means, a clear association between a first connection fitting and a second connection fitting of a bayonet for connecting a fluid line adapter to an adapter receiving member can be provided. The bayonet in this case has at least two locking arms, which are arranged on the first connection fitting. In addition, the bayonet comprises a flange ring with grooves on the second connection fitting. In this case, the number of the grooves is equal to the number of the locking arms. When viewed in the axial direction of the device, the locking arms are arranged in a star-shaped manner around the end piece of the fluid line adapter. The same applies to the grooves on the flange ring, which have an inner ring diameter that can guide the end piece of the fluid line adapter through. At the location of the grooves, the inner ring diameter of the flange ring increases, wherein the locking arms can be guided through the flange ring at the location of the grooves. In order to connect the bayonet, the first connection fitting is connected to the second connection fitting, wherein the locking arms are guided through the grooves of the flange ring. Since the locking arms and the grooves produce a positioning of the connection fittings relative to each other due to their geometry, the first connection fitting and the second connection fitting can only be connected to each other in one predetermined position. In addition, the mechanical coding device includes a first coding partner, which mechanically cooperates with a second coding partner, wherein the two coding partners are constructed to be compatible with each other. Using the mechanical coding device, when the pin is connected, an automatic association is generated between the first connection partner and the second connection partner. The first connection partner, which is not intended to be associated with the second connection partner, has a first coding partner that is not oriented to be compatible with the second coding partner. In this case, since the first connection partner and the second connection partner are incompatible, the connection between the first connection partner and the second connection partner is impossible because the connection partners can only be oriented relative to each other in a predetermined position. When the first connection partner is intended to be associated with the second connection partner, the first connection partner has a first coding partner oriented in a predetermined position to be compatible with the second coding partner.
[0008] Alternatively or additionally, the first groove can, for example, have a geometry that differs from the standard geometry of the groove, wherein the corresponding first locking arm has a compatible complementary geometry. In this case, for example, either the corresponding locking arm can only be guided through this groove, or, alternatively, the corresponding locking arm cannot be guided through the other groove. Thus, in combination with the mechanical coding device, a mechanical relationship is generated between the two connection partners without significant complexity.
[0009] In this case, when the user wishes to associate the fluid line adapter with the corresponding receiving member, he no longer has to decode the mark and connect it to another mark. Thus, incorrect association of the fluid lines connected to the fluid line adapter and the adapter arm receiving member is prevented. This improves the efficiency of the device handling.
[0010] For example, the first locking arm may have a larger extent in the circumferential direction of the bayonet than the other locking arms, wherein the first groove has a compatible extent in the circumferential direction and the additional groove has a smaller extent in the circumferential direction which is incompatible with the first locking arm.
[0011] In this example, one of the locking arms, the first locking arm, comprises a greater extent in the circumferential direction than the other locking arm and therefore cannot be guided through a groove compatible with the other locking arm. The first locking arm is therefore too large. The first connection fitting can therefore only be connected to the second connection fitting in a position where the first locking arm is aligned with the first groove in order to lock the bayonet. Thus, on the one hand, the first connection fitting is associated with the second connection fitting. On the other hand, a predetermined positioning of the two connection fittings relative to each other is thereby achieved without significant complexity.
[0012] Furthermore, the first coding matching element may be, for example, a protrusion, and the second coding matching element may be a recess.
[0013] In this case, the projection is compatible with the recess, that is, the projection can be introduced into the recess and moved therein when the bayonet is intended to be locked. The projection can be introduced into the recess only at a predetermined position of the first connection fitting relative to the second connection fitting. The first connection fitting is thus associated with the second connection fitting.
[0014] According to one example, the protrusion may extend away from the first connection fitting in the radial direction of the fluid line adapter, wherein the second connection fitting has an edge extending circumferentially of the adapter receiving member, and the edge has a circumferentially extending guide for the protrusion.
[0015] In this example, the protrusion protrudes radially outwards away from the first connection fitting and thus away from the fluid line adapter. In this case, when the first connection fitting is arranged on the second connection fitting and connected thereto, the edge surrounds the first connection fitting. In this case, the protrusion can be arranged in the guide and move circumferentially along the guide when the bayonet is locked.
[0016] In another example, the protrusion may extend away from the fluid line adapter in the axial direction of the fluid line adapter, wherein the second connection fitting has a guide for the protrusion extending in the circumferential direction of the adapter receiving member.
[0017] In this example, in connection of the first connection fitting to the second connection fitting, the protrusion is arranged in a guide arranged in the adapter receiving member. When the bayonet is closed, the protrusion can move in the circumferential direction along the guide.
[0018] In this case, for example, the second coding mating element can have a stop element which, in the locked position of the device, forms a positive locking connection with the projection in the circumferential direction.
[0019] Via the stopper, it is indicated to the user that the first connection fitting and the second connection fitting are installed and locked in the correct position.
[0020] According to another example, the first connection fitting may have three locking arms.
[0021] However, it is not excluded that the first connection fitting may have a greater or lesser number of locking arms.In addition, the second connection fitting accordingly comprises three grooves through which the locking arms may be guided.
[0022] The invention also relates to a device group according to the preceding description comprising a plurality of said devices, wherein each of said plurality of devices has encoding means for clearly identifying the device by being different from said encoding means in other devices of said plurality of devices.
[0023] Due to the difference in the encoding means of each device from the device group, each device has a first connection fitting and a second connection fitting, which cannot be used with each other when they come from different devices. Therefore, the risk of confusion between each device in the plurality of devices can be prevented. In addition, when each device is installed, automatic recognition of the correct pairing between the first connection fitting and the second connection fitting can be provided by enabling the connection between the first connection fitting and the second connection fitting.
[0024] In one example, when the fluid line adapters of a plurality of devices each have a fluid line bend, each of the plurality of devices may have a separate angular relationship between a respective encoding device and a respective fluid line bend.
[0025] Since the fluid line bend in the assembled state must face in a specific direction, the angular relationship specific to the respective arrangement between the encoding device and the fluid line bend results in a correct positioning of the fluid line bend of the fluid line adapter in the connection between the first connection fitting and the second connection fitting. This simplifies the assembly of the device or the fluid line adapter on the adapter receiving component.
[0026] According to another example, a first coded mating component of one of the plurality of devices and a second coded mating component of another of the plurality of devices may be incompatible.
[0027] Due to the incompatibility between the first coding mating element of one of the plurality of devices and the second coding mating element of another of the plurality of devices, mixing up of connection mating elements of different devices in the device group is prevented.

[0060] like Figure 1 As shown, a device according to the present invention is generally indicated by reference numeral 10.
[0061] In this case, the device 10 comprises a fluid line adapter and an adapter receiving member, wherein the fluid line adapter has a first connection fitting 12 and the adapter receiving member has a second connection fitting 14. The first connection fitting 12 and the second connection fitting 14 can be connected to each other to connect the fluid line adapter to the adapter receiving member. This assembled state is as shown in FIG. Figure 1 shown.
[0062] like Figure 2aAs shown, the first connection fitting 12 comprises at least two locking arms 16, 18, 20, which are arranged in a star-shaped manner in the end piece of the fluid line adapter. In this case, the locking arms 16, 18, 20 extend in the radial direction 48 of the fluid line adapter and face away from the fluid line adapter. In this example, three locking arms 16, 18, 20 are provided.
[0063] Furthermore, the locking arms 16, 18, 20 extend along the circumferential direction 46 of the fluid line adapter. In this example, the extension of the locking arm 16 in the circumferential direction 46 is greater than the extensions of the other locking arms 18, 20. The locking arm 16 may be referred to as a first locking arm 16.
[0064] according to Figure 2b , the second connection fitting 14 has a flange ring 22. The flange ring 22 has grooves 24, 26, 28 along its inner circumference, and the grooves 24, 26, 28 are configured to be compatible with the locking arms 16, 18, 20. That is, when the locking arms 16, 18, 20 are aligned with the grooves 24, 26, 28, the locking arms 16, 18, 20 can be guided through at least one of the grooves 24, 26, 28. However, in this case, the extent of the grooves 26 and 28 in the circumferential direction 46 is smaller than that of the first locking arm 16. Therefore, the first locking arm 16 cannot be guided through the grooves 26 and 28. Only the groove 24, which can be called the first groove 24, has a geometric shape in the circumferential direction 46 that can guide the first locking arm 16 through. Therefore, the first locking arm 16 can only be guided through the first groove 24. Therefore, the connection between the first connection fitting 12 and the second connection fitting 14 is possible only in one predetermined position.
[0065] The fluid line adapter may also have a sealing element 38 in the form of an O-ring which seals the connection between the first connection fitting 12 and the second connection fitting 14 when the locking arms 16 , 18 , 20 have been guided through the grooves 24 , 26 , 28 .
[0066] Figure 3 A further view of the device 10 is shown. The mechanical encoding device comprises a projection 30 as a first encoding partner 42 in this example, which extends radially away from the first connection partner 12 .
[0067] The adapter receiving member serving as the second connection fitting 14 includes a guide 34 provided at the edge 32 and serving as the second marking fitting 44. The guide 34 may be formed as a groove of the edge 32 in the circumferential direction.
[0068] Furthermore, the second connection member 14 comprises a stopper 52, which prevents the protrusion 30 from further rotating in the circumferential direction by a positive locking connection in the assembled position of the device 10. When the protrusion 30 is arranged on the stopper 52, it is thereby indicated that a correct connection has been made between the first connection fitting 12 and the second connection fitting 14. The user can refer to the protrusion 30 to recognize whether the first connection fitting 12 and the second connection fitting 14 have been correctly connected and locked to each other.
[0069] Figure 4a Another view shows the first connection fitting 12 of this example. In this case, the first connection fitting 12 also includes three locking arms 16, 18, 20. The protrusion 30 is arranged spaced apart from the end piece of the fluid line adapter in the axial direction 50. The sealing element 38 is arranged between the protrusion 30 and the locking arms 16, 18, 20.
[0070] The fluid line adapter also has a fluid line bend 54 so that the two end pieces of the fluid line adapter are arranged at an angle relative to each other. In this case, the protrusion 30 is arranged between the fluid line bend 54 and the locking arms 16 , 18 , 20 .
[0071] In this case, the connection fitting 12 has a predetermined angular relationship between the projection 30 and the fluid line bend 54, wherein the projection 30 serves as the first coding fitting 42. This angular relationship in this case determines the direction relative to the adapter receiving component on which the second connection fitting 14 is arranged, wherein the fluid line bend 54 extends in the second connection fitting 14 after assembly.
[0072] In this instance, Figure 4b The adapter receiving member of this example is shown. The adapter receiving member, which serves as the second connection fitting 14, also comprises a flange ring 22 with grooves 24, 26, 28. Only the groove 24 is visible in this figure. Due to the cooperation of the first coding fitting 42 and the second coding fitting 44, which is in the form of a guide 34 in the form of an edge 32 and has a predetermined position generated by the locking arms 16, 18, 20 and the grooves 24, 26, 28, a fixed association is provided between the connection fittings 12, 14. Therefore, the orientation of the fluid line bend 34 relative to the adapter receiving member in the assembled position is also determined.
[0073] according to Figure 5a and 5b As another example of the device 10, the device 30 may also be oriented in the axial direction 50. Figure 5a, which shows the first connecting fitting 12 .
[0074] Figure 5b The second connection fitting 14 is shown, which shows a correspondingly configured guide element 34 as a second coding fitting 44. In this example, the guide element 34 is arranged inside the adapter receiving component.
[0075] Figure 6a and 6b A first connection partner 12 of a device 10 of a device group is shown, wherein the device group has a plurality of devices 10. In this case, the devices 10 have mechanical coding means which differ between the various devices 10.
[0076] At this point, Figure 6a In the figure, the first coding matching piece 42 is arranged at the lower right of the figure as a protrusion 30.
[0077] exist Figure 6b In the figure, the first coding matching piece 42 is arranged at the lower left of the figure as a protrusion 30.
[0078] In this regard, Figure 2a A further device 10 of the device set is shown, in which the first coding mating element 42 is arranged at the top in the figure as a protrusion 30 .
[0079] The first connection fitting 12 and the second connection fitting 14 can be clearly associated with each other due to the different first coding fittings 42 of the device 10. Thus, mixing up different connection fittings 12, 14 belonging to different devices 10 is prevented.
[0080] Figure 7 A distributor plate 40 for fluid lines is shown, as well as a fluid line 36 connected to the distributor plate 40 by means of the device 10. In this case, the fluid line 36 is connected to a fluid line adapter, i.e. a first connection fitting 12. The distributor plate 40 has an adapter receiving member, i.e. a second connection fitting 14. The first connection fitting 12 is associated in a clear manner with the second connection fitting 14 by means of corresponding coding means.
[0081] The present invention is not limited to one of the above-described embodiments but can be modified in various ways.
[0082] All features and advantages resulting from the claims, the description and the drawings, including constructional details, spatial arrangements and method steps, may be essential to the invention per se and in many different combinations.
