Abstract
Description
Technical Field
[0001] The invention relates to a contact arrangement for a plug connector part according to the preamble of claim 1 , and to a plug connector part having such a contact arrangement. Background Art
[0002] This contact assembly comprises a contact element, which has a connection section for connecting an electrical conductor and is made as a solid component from a metal material by turning and / or milling. The contact assembly also comprises an electrically conductive conductor rail element having a connection section and a fixing element, the conductor rail element being connected to the contact element via the fixing element.
[0003] Such a contact assembly can be, for example, a component of a plug connector component which is designed as a so-called heavy-duty plug connector, also called an industrial plug connector, and which can be connected to a corresponding mating plug connector component. By combining a plug connector component and a corresponding mating plug connector component, for example, two cables can be connected to one another or a cable can be connected to an electrical device, for example in a switch cabinet or on a switch cabinet, in order to establish an electrical connection between the components in this way. Such a plug connector component can, for example, be designed to be load-bearing and resistant, in particular also to be moisture-proof, so that such a plug connector component can be used in a load-bearing environment, for example an industrial environment, in combination with a corresponding mating plug connector component, in order to establish an electrical connection.
[0004] In such plug connector parts, the contact elements are used, for example, to transmit high currents during operation. For this reason, the contact elements are produced as solid parts from metal material by turning and / or milling and are thus produced in one piece, so that the contact elements can have a relatively high current-carrying capacity. Such contact elements can be connected, for example, by plugging with corresponding mating contact elements of a mating plug connector part and can be insensitive to loads due to their solid design.
[0005] The contact elements of the contact assembly of the plug connector part are mechanically and electrically connected to the electrically conductive conductor rail elements, so that the current can be conducted via the conductor rail elements between the contact elements and another electrical component, for example another contact element. In this case, the conductor rail elements and the contact elements are possibly made of different materials and also by different manufacturing methods, which may make the connection between the conductor rail elements and the contact elements difficult. For example, a material connection between the contact elements and the corresponding conductor rail elements, for example by welding or soldering, may not be easily realized in a load-bearing, stable manner.
[0006] There is therefore a need to establish a reliable connection between a contact element and a corresponding conductor rail element in a contact arrangement.
[0007] Contact arrangements are known from DE 20 2006 003 480 U1 and DE 10 2015 212 898 A1, in which a contact element is connected to a corresponding clamping spring of a spring force connection.
[0008] In the contact arrangement disclosed by DE 20 2017 107 035 U1, a protective contact element formed as a stamped bent part is connected to a corresponding conductor rail element. Summary of the invention
[0009] The object of the present invention is to provide a contact arrangement and a plug-in connector component having such a contact arrangement, which allow a connection of a contact element manufactured as a solid component to a corresponding conductor rail element in a simple and reliable manner.
[0010] This object is achieved by the subject matter having the features of claim 1 .
[0011] Accordingly, the contact element has a fastening section which forms a contact surface on which the connecting section of the busbar element is supported and to which the connecting section of the busbar element is fastened.
[0012] The contact element is mechanically and electrically connected to the corresponding conductor rail element. For this purpose, a fixing section is formed on the contact element, which is formed with a contact surface, on which the conductor rail element is supported by the connecting section. The conductor rail element is thus in contact with the contact surface of the contact element via the connecting section and is thus connected to the contact element both mechanically and electrically.
[0013] In one embodiment, the conductor rail element is formed as a stamped and bent part from a metal sheet. In particular, the conductor rail element can have a base, relative to which the connecting section is bent. The conductor rail element is made, for example, of a material that is softer than the material of the contact element.
[0014] In one embodiment, a first fixing opening is formed on the fixing section, and a second fixing opening is formed on the connecting section. The fixing element passes through the first fixing opening and the second fixing opening in order to connect the conductor rail element to the contact element.
[0015] In this design, the conductor rail element is fixed to the contact element via a fixing element, which passes through a fixing opening on the fixing section of the contact element and a fixing opening of the connecting section of the conductor rail element, and thus fixes the conductor rail element and the contact element to each other. Thus, the conductor rail element is in contact with the contact surface of the contact element via the connecting section, wherein the connecting section is held on the contact element by the fixing element and thus fixed to the contact element.
[0016] In one embodiment, the fixing element is a rivet element. The rivet element passes through the fixing opening at the fixing section of the contact element and the fixing opening at the connecting section of the conductor rail element, and thus fixes the connecting section to the fixing section in a form-fitting manner. This riveted connection can preferably be designed to be airtight, so that no harmful gases can enter the area of the connection point between the contact surface of the connecting section and the fixing section, and thus protect the connection between the contact element and the conductor rail element from corrosion. In addition, the form-fitting connection established by the rivet element is mechanically stable and electrically reliable, so that the contact element and the conductor rail element are mechanically and electrically reliably connected to each other. In addition, this connection can be designed to be space-friendly and therefore does not contribute significantly to the construction space of the contact assembly.
[0017] In another embodiment, the fastening element can be formed by a screw. By means of such a screw, a threaded connection can be established between the contact element and the conductor rail element, wherein the screw, for example, is passed through one of the fastening openings (without an internal thread) and screwed into the other fastening opening (with an internal thread). In another embodiment, the screw can be passed through both fastening openings (without an internal thread) and screwed with an additional mounting element, such as a nut, in order to fasten the contact element and the conductor rail element to each other in this way by means of a threaded connection.
[0018] In addition or as an alternative to fixing the coupling section to the fixing section via fixing elements, for example in the form of rivet elements or screw elements, an engaging element can be formed on the fixing section, which engages into an engaging opening on the coupling section to fix the coupling section to the fixing section. Such an engaging element can be formed, for example, by a projection on the fixing section, which engages with the engaging opening of the coupling section for engagement and is subsequently plastically deformed, in order to provide a preferably positive or non-positive connection between the coupling section and the fixing section in this way, and thus fix the coupling section to the fixing section.
[0019] In one embodiment, the contact surface extends flat along a plane, wherein the connecting section of the busbar element extends flat along a plane. The contact surface is formed flat on the fixing section of the contact element so that the connecting section of the conductor rail element can be flatly contacted. The fixing element presses the contact surface and the connecting section against each other, thereby establishing a mechanically stable and also electrically reliable connection between the contact element and the conductor rail element.
[0020] In one embodiment, the contact assembly has a spring element which is operatively connected to the contact element. The spring element is designed to act in a clamping manner on the electrical conductor in order to connect the electrical conductor to the connecting section of the contact element. Such a spring element can realize a dynamic spring connection for connecting the electrical conductor. When connecting the electrical conductor, the spring element bears against the electrical conductor in an electrically clamping manner and clamps the conductor to the connecting section of the contact element, thereby connecting the electrical conductor to the contact element. By moving the spring element, the clamping effect on the electrical conductor can be released in order to (again) release the electrical conductor from the contact element.
[0021] In one embodiment, the spring element has a supporting leg and a clamping leg. The supporting leg is supported on the contact element. The clamping leg can be elastically deflected relative to the supporting leg for connecting the electrical conductor. This deflection can be achieved by the electrical conductor to be connected itself during the connection. However, the deflection can also be carried out by means of an operating element or a tool, by means of which the clamping leg can be placed in a release position before the electrical conductor is connected, so that the electrical conductor can be placed on the connecting section of the contact element in a substantially forceless manner, so that the clamping leg is subsequently transferred to the clamping position and the conductor is clamped on the connecting section in the case of electrical contact and mechanical locking with the contact element.
[0022] In one embodiment, the contact element has a form-fitting element, via which the spring element is fixed to the contact element. The spring element is thus connected to the contact element in a form-fitting manner and is thus supported directly on the contact element. The form-fitting element can, for example, be inserted into a corresponding fixing opening on the support leg, thereby fixing the support leg on the contact element. The clamping leg can be pivoted relative to the support leg in order to connect the electrical conductor to the connecting section of the contact element.
[0023] In one embodiment, the contact element has a plug-in contact section for plug-in connection with a mating contact portion of a mating plug connector part along a plug-in direction. Such a plug-in contact section can be formed, for example, by a solid contact pin that can be inserted into a contact socket of a mating plug connector part, or by a contact socket into which a contact pin of a mating plug connector part can be inserted. Thus, a plug-in connection with a mating contact portion of a mating plug connector part can be established via the plug-in contact section, in order to establish an electrical connection of the connected electrical conductor in this way.
[0024] In one embodiment, the contact element extends longitudinally along the longitudinal axis. The connecting section is formed on a first side of the fixing section, viewed axially along the longitudinal axis, and the plug-in contact section is formed on a second side of the fixing section facing away from the first side, so that the fixing section (viewed axially along the longitudinal axis) is arranged between the connecting section and the plug-in contact section. The fixing section thus occupies an axial middle position between the plug-in contact section on one side and the connecting section on the other side. Thus, an additional functional section is formed on the elongated contact element between the plug-in contact section on one side and the connecting section on the other side, which realizes the fixing section and via which the conductor rail element is connected to the contact element.
[0025] For example, the contact surface can be formed on a side surface of the fastening section which faces outwards transversely to the longitudinal axis.
[0026] In one embodiment, the contact assembly has a further contact element, which has a further connection section for connecting a further electrical conductor and is produced as a solid component from a metal material by turning and / or milling. The further contact element has a further fixing section, which forms a further contact surface, on which a further connection section of the conductor rail element is supported.
[0027] The contact elements are thus mechanically and electrically connected to one another via the conductor rail elements, so that the contact elements are at the same potential. Here, for example, one of the contact elements can have a plug-in contact section, while the other contact element does not have such a plug-in contact section. An electrical line can be connected to each contact element, so that the electrical lines can be at the same potential via the contact assembly, and one of the contact elements can be connected to a corresponding mating contact of a mating plug connector part via the plug-in contact section.
[0028] The contact elements are each produced as a solid component from a metal material in one piece by turning and / or milling. For example, the conductor rail element, which is produced as a stamped and bent part from a softer sheet metal, establishes the connection between the contact elements and also conducts the current between the contact elements.
[0029] In order to connect the conductor rail element to the further contact element, in one embodiment, a further first fixing opening can be formed on the further fixing section of the further contact element, and a further second fixing opening can be formed on the further connecting section of the conductor rail element. The further fixing element can be passed through the further first fixing opening and the further second fixing opening and thereby also fix the conductor rail element to the further contact element. This can be achieved, for example, by means of rivet elements or by means of screws on the further fixing element.
[0030] Alternatively or additionally, in one embodiment, a further engagement element can be formed on the further fixing section, which engages in a further engagement opening of the further coupling section to fix the further coupling section to the further fixing section. The further engagement element can be formed, for example, by a projection on the further fixing section, which engages with the further engagement opening of the further coupling section for engagement and is subsequently plastically deformed, so as to provide a preferably positive or non-positive connection between the further coupling section and the further fixing section in this way, and thus fix the further coupling section to the further fixing section.
[0031] For example, a plug connector part having a contact assembly of the type described above may include a plug connector housing and a contact insert accommodated in the plug connector housing. The contact assembly is arranged on the contact insert, wherein the arrangement of the contact elements of one or more contact assemblies provides a plug surface on the contact insert and a plug surface on the plug connector part. The contact insert may be designed in a modular manner, so that the plug connector part can be adapted to a given application by being equipped with a contact insert from a plurality of available modular contact inserts.
[0032] In one embodiment, the contact insert has a holding frame and at least one contact module held on the holding frame. The contact assembly is preferably arranged on the at least one contact module. The holding frame can, in particular, surround a holding opening in a frame-shaped manner, wherein one or more contact modules can be arranged and accommodated in the holding opening. By combining modular contact modules on the holding frame, a variably adaptable contact insert can be provided in a modular manner, which contact insert can be accommodated in a plug connector housing of a plug connector part in order to provide a plug surface on the plug connector part for connection with a corresponding mating plug connector part.
[0033] At least one contact module preferably has a plug section for plug connection with a mating plug connector part. The plug contact section of the contact element of one or more contact assemblies is located in the area of the plug section so as to establish electrical contact with the mating contact portion of the mating plug connector part when plugged with the mating plug connector part.

[0047] Figure 1 A schematic diagram of a plug connection device 1 is shown, which includes a plug connector part 2 and a corresponding mating plug connector part 3. The plug connector part 2 and the mating plug connector part 3 can be plug-connected to each other along a plug direction E, so that the plug connector part 2 and the mating plug connector part 3 are connected to each other via the plug surfaces 22, 32, and electrical contact is established between the contact elements of the plug connector part 2 and the mating plug connector part 3.
[0048] In the illustrated embodiment, the plug connector part 2 is connected to an electrical cable 21, which is introduced into the plug connector housing 20 of the plug connector part 2 through a cable outlet 200. In contrast, the mating plug connector part 3 is arranged on a component 31, for example, on a switch cabinet wall, so that the cable 21 can be connected to the component 31 via the plug connection device 1.
[0049] In another embodiment, the plug connector part 2 and the corresponding mating plug connector part can be connected to corresponding cables, for example, respectively, so that electrical cables can be connected to each other via the plug connection device 1 .
[0050] The plug connector part 2 and the corresponding mating plug connector part 3 can in particular be so-called heavy-duty plug connectors, also called industrial plug connectors, which can be used in load environments, in particular industrial environments, and are designed to be correspondingly stable and load-bearing.
[0051] As in accordance with Figure 2 As shown in the schematic diagram of , a contact insert 23 is accommodated in the plug connector housing 20 of the plug connector part 2, which contact insert forms a plug surface 22 and on which a setting of contact elements for plug connection with corresponding mating contact elements of the mating plug connector part 3 is arranged.
[0052] The contact insert 23 can be a so-called fixed-pole contact insert which has a fixed arrangement of the contact elements.
[0053] However, the contact insert 23 may also be a modular contact insert which can be assembled in a modular manner and thus configured in a modular manner in order to provide different plug-in surfaces 22 adapted to a given application.
[0054] exist Figure 2 In the embodiment schematically shown in FIG. 1 , the contact insert 23 has a holding frame 230, on the end faces of which grounding elements 231, 232 (also referred to as grounding strips) are arranged respectively. The protective wire 211 guided in the cable 21 is connected to one or both of the grounding elements 231, 232, and the protective wire is used to transmit a protective potential (grounding potential). The grounding elements 231, 232 have grounding contacts 233, 234, which are designed to contact corresponding grounding contacts of the mating plug connector part 3 in a plug-in manner, so as to transmit the protective potential between the plug connector part 2 and the mating plug connector part 3.
[0055] The holding frame 230 forms a frame-shaped holding opening in which slots are formed, on which contact modules 4 can be accommodated, so as to modularly assemble the contact inserts 23 with the desired combination of contact modules 4. Thus, the contact modules 4 with the contact elements arranged thereon form the plug-in surfaces 22, which can be plug-connected to the corresponding matching, complementary plug-in surfaces 32 of the mating plug connector part 3.
[0056] Figure 3 and Figure 4 An embodiment of such a contact module 4 is shown, which can be arranged on a holding frame 230 and can be connected to the holding frame 230 by snap-locking via snap-locking elements 402 on a module housing 40. Such a contact module 4 can be combined with other (similar or different) contact modules 4 on the holding frame 230, so that a contact insert 23 is constructed by a combination of such contact modules 4.
[0057] In the illustrated embodiment, the housing 40 is composed of housing parts 400, 401, which can be plugged together to complete the module housing and are connected to each other in a latching manner in the assembled position. On the housing part 400, latching elements 402 are formed on both sides on the sides pointing away from each other, so that the contact module 4 can be connected to the holding frame 230 of the contact insert 23 via the module housing 40 in a latching manner.
[0058] In the exemplary embodiment shown, the contact module 4 has a plurality of contact devices, each of which comprises two contact elements 42, 43 and a conductor rail element 48. The contact elements 42, 43 are connected to one another in pairs by the conductor rail element 48 and are thus mechanically and electrically fixed to one another.
[0059] In the embodiment shown, Figure 4 Combination Figure 5 It can be seen that the contact elements 42 each have a connecting section 420 and a fastening section 421 axially connected thereto.
[0060] The contact element 43, similar to the contact element 42, has a connecting section 430 and a fixing section 431 axially connected thereto, such as from Figure 4 Combination Figure 6 In this case, a plug contact section 435 extending longitudinally along the longitudinal axis L in the form of a contact pin is additionally connected to the fixing section 431 and comes into plug contact with a corresponding mating contact of the mating plug connector part 3 when the plug connector part 2 is plugged in.
[0061] Each contact element 42, 43 carries a spring element 46, 47, which is connected to the form-fitting elements 424, 434 on the fixing sections 421, 431 via support legs 460, 470 and is thus fixed to the contact elements 42, 43. The clamping legs 461, 471 can be elastically deflected relative to the support legs 460, 470, and the clamping legs extend into the area of the connecting sections 420, 430 of the corresponding contact elements 42, 43 in such a way that the electrical conductors 210 (see FIG. 211 ) inserted into the connecting sections 420, 430 are clamped via the spring elements 46, 47. Figure 2 ) is clamped to the contact elements 42, 43 and is thus mechanically and electrically connected to the contact elements 42, 43.
[0062] In order to release the conductor 210, the clamping legs 461, 471 can be elastically deflected relative to the support legs 460, 470 via the respectively associated actuating element 41, so that the clamping legs 461, 471 are transferred from the clamping position to a release position, in which the electrical conductor 210 is not (any more) clamped on the connecting sections 420, 430. In addition, the clamping legs 461, 471 can also be deflected into the release position by the actuating element 41, so that the electrical conductor 210 for connection to the corresponding contact element 42, 43 can be inserted essentially forcelessly.
[0063] In the exemplary embodiment shown, the contact elements 42, 43 thus each enable the connection of an electrical line 210, so that a plurality of electrical lines 210 can be connected to the contact module 4. In this case, every two contact elements 42, 43 are electrically and mechanically connected to one another via a corresponding conductor rail element 48, so that the lines 210 connected to the contact elements 42, 43 are placed in pairs at the same potential via the corresponding conductor rail elements 48.
[0064] Via the plug contact sections 435 of the contact elements 43 , the pair of contact elements 42 , 43 can be connected to corresponding mating contacts during a plug connection with the mating plug connector part 3 .
[0065] In the illustrated embodiment, the contact 42 is accommodated in the chamber 406 of the housing part 401. In contrast, the contact element 43 is accommodated in the chamber 407 of the housing part 401 and extends into the region of the plug section 405 on the housing part 401 via the plug contact section 435, so that when the plug connector part 2 is plugged and connected to the corresponding mating plug connector part 3, the plug contact section 435 of the contact element 43 can be plugged and connected to the corresponding mating contact element.
[0066] In the embodiment shown, the contact elements 42, 43 are each formed as a solid component from a piece of metal material by turning and / or milling. Thus, the contact elements 42, 43 are each solidly made from a single piece by a cutting manufacturing method by removing material. Thus, sections such as the fixing sections 421, 431 and the plug-in contact section 435 are solid. The recesses on the connecting sections 420, 430 and non-rotationally symmetrical sections such as the fixing sections 421, 431 are formed, for example, by milling. The plug-in contact section 435 can be formed, for example, by turning.
[0067] An electrical line 210 can be connected to each contact element 42, 43 along a connection direction A, such as, for example, from Figure 8 In the embodiment shown, the connecting section 420, 430 of each contact element 42, 43 has a U-shape in a cross section transverse to the connecting direction A, and a connecting cavity is configured in this way, into which the conductor 210 is introduced when connected to the corresponding contact element 42, 43. The clamping legs 461, 471 of the respective spring elements 46, 47 engage in the connecting cavity in order to clamp the conductor 210 with the contact elements 42, 43 in the connecting cavity of the connecting sections 420, 430.
[0068] In contrast, the conductor rail element 48 is formed as a stamped and bent part from a metal sheet and is made, for example, of a softer material than the contact elements 42, 43. Figure 5 and 6 As can be seen in FIG. 4 , the base 480 is provided, to which the connecting sections 481 , 482 are bent at the axial ends, so that the connecting sections 481 , 482 are each arranged at a right angle to the base 480 . This results in a corresponding U-shaped busbar element 48 .
[0069] On the fastening sections 421 , 431 of the contact elements 42 , 43 , respectively, a flat contact surface 423 , 433 is formed, against which the connecting sections 481 , 482 of the corresponding busbar element 48 respectively lie flat and are thus supported on the contact elements 42 , 43 .
[0070] In the illustrated embodiment, fixing openings 422, 432, 483, 484 are formed at the fixing sections 421, 431 and at the corresponding connecting sections 481, 482, and fixing elements 44, 45 in the form of riveted elements are respectively engaged through the fixing openings, so that each contact element 42, 43 is connected to the corresponding connecting section 481, 482 of the corresponding conductive rail element 48 via a riveted connection.
[0071] like Figure 5 and Figure 6As shown, in the illustrated embodiment, each fixing element 44, 45 has a shank 440, 450 extending axially from a head 441, 451. The rivet element passes through the fixing openings 422, 483; 432, 484 of the corresponding connecting sections 481, 482 on the fixing sections 421, 431 of the corresponding contact elements 42, 43 and on the conductor rail element 48 with the shank 440, 450, wherein the head 441, 451 is located on the outer side of the contact elements 42, 43 facing away from the conductor rail element 48, and the ends 442, 452 of the shanks 440, 450 are plastically deformed in the region of the connecting sections 481, 482 to establish the riveted connection, such as this. Figure 8 As can be seen in .
[0072] By connecting the contact elements 42, 43 in pairs to the corresponding conductor rail elements 48, a fixed mechanical and electrical connection in pairs is established between the contact elements 42, 43. In this case, the connection is preferably gas-tight, so that no harmful gases can reach from the outside in the area of the connection between the fixing sections 421, 431 and the corresponding corresponding connecting sections 481, 482.
[0073] Since the connection between the conductor rail element 48 and the corresponding corresponding contact element 42, 43 is established by a riveted connection in each case, differences in material properties and tolerances can be compensated in a simple manner. In particular, a strong, durable connection can be produced between the conductor rail element 48, which is designed as a stamped bent part, and the corresponding contact element 42, 43, which is formed as a solid part in one piece by turning and / or milling. Such a connection can be mass-produced in particular. In this case, the connection is space-efficient and only takes up insignificant space requirements of the contact device.
[0074] Figures 9 to 12 A further exemplary embodiment of a contacting module 4 is shown, in which the contacting devices each have two contact elements 42 , 43 , which are connected to one another via a busbar element 48 .
[0075] As will be explained below, apart from the connection of the conductor rail elements 48 to the contact elements 42 , 43 , the contact module 4 with the contact arrangement of the contact elements 42 , 43 accommodated between the housing parts 400 , 401 is functionally identical to the previously described exemplary embodiment, so that reference is made to the above-described embodiments in full.
[0076] exist Figures 9 to 12In the illustrated embodiment, coupling elements 426, 436 are molded on the fixing sections 421, 431 of the contact elements 42, 43, i.e., on the abutment surfaces 423, 333, which are engaged in corresponding coupling openings 485, 486 for connection with the connecting sections 481, 482 of the conductor rail element 48, thereby establishing a fixed connection between the contact elements 42, 43 and the conductor rail element 48 in the assembled position.
[0077] In this case, each two contact elements 42, 43 are mechanically and electrically connected to each other via a conductor rail element 48. Engagement elements 426, 436 are respectively formed on the contact surfaces 423, 433 of the fixing sections 421, 431 of the contact elements 42, 43, which protrude as projections relative to the corresponding contact surfaces 423, 433 and engage in engagement openings 485, 486 on the corresponding connection sections 481, 482 of the conductor rail element 48 in the assembled position.
[0078] Here, a form-fitting or force-fitting connection can be achieved in that, after the corresponding joining elements 426, 436 are joined with the corresponding joining openings 485, 486, the joining elements 426, 436 are plastically deformed and thus a non-releasable (at least non-destructively releasable) connection is achieved between the corresponding contact elements 42, 43 and the corresponding conductor rail elements 48.
[0079] In other respects, according to Figures 9 to 12 The embodiment is the same as the previously described embodiment, so reference should also be made to the previous implementation plans and descriptions.
[0080] In accordance with Figures 9 to 12 In the embodiment of the present invention, a mechanical and electrical connection between the contact elements 42, 43 can also be established by connecting the contact elements 42, 43 in pairs to the corresponding conductor rail elements 48. In this case, in this embodiment, the connection is also preferably gas-tight, so that no harmful gases can reach the area of the connection between the fixing sections 421, 431 and the corresponding connecting sections 481, 482 from the outside.
[0081] Since the connection between the conductor rail element 48 and the corresponding corresponding contact element 42, 43 is established by a form-fitting connection or a non-positive form-fitting connection, differences in material properties and tolerances can also be compensated in a simple manner in this embodiment. In particular, a strong, permanent connection can be established between the conductor rail element 48, which is designed as a stamped bent part, and the corresponding contact element 42, 43, which is formed from a single piece by turning and / or milling as a solid part. Such a connection can be produced in series in particular. In this case, the connection is space-efficient and only takes up insignificantly the space requirement of the contact device.
[0082] The concept on which the present invention is based is not limited to the above-described exemplary embodiments but can also be realized in other ways.
[0083] Contact arrangements of the type described can in principle be used in completely different plug connector components for completely different application purposes.
[0084] Such a contact device can include one or more contact elements. In particular, it is also conceivable to connect a (single) contact element to a conductor rail element and via the conductor rail element to further electrical components.
[0085] The connecting section of the contact element can be designed in combination with the spring element to provide a spring-force connection. However, such a connecting section can also be designed, for example, to connect an electrical conductor by a crimping connection or a screw connection.
