Description

Technical Field

[0001] The invention is based on a switching plug connector system of the type according to independent claim 1 .

[0002] Furthermore, the invention is based on an appliance wiring arrangement having a switching plug connector system according to claim 1 and a plurality of cables.

[0003] Such switching plug connector systems are required, for example, in order to electrically connect electrical devices to one another and / or to disconnect them from one another in order to achieve a desired signal flow. Background Art

[0004] Publication DE 195 39 957 A1 discloses a switch connector for electrical plug connections, which has a blade contact strip and a spring contact strip. The switch connector includes a contact device, which connects two selected blade elements to each other when the blade contact strip and the spring contact strip are separated from each other, wherein the contact between the selected blade elements is released when the blade contact strip and the spring contact strip are plugged together.

[0005] EP 702 431 A2 discloses a switch connector for a strip connector at a circuit board, in particular a data bus printed circuit board. The switch connector has a plurality of sockets for accommodating blade contact strips. The socket strip contains contact elements respectively associated with at least two sockets, which form a short-circuit bridge between the sockets as long as no blade contact is inserted. Here, inserting the blade contact strip and thus unfolding the elements accommodating the blade contact causes the short-circuit bridge to be interrupted. The short-circuit bridge is produced by direct contact between the sockets or via a contact plug-in inserted into a basic body carrying the socket strip.

[0006] The disadvantage of this prior art is that the known arrangements do not meet many currently existing requirements. In particular, it is common, for example, in industrial environments, control facilities, digital service stations, in laboratories and research institutions, and in many other facilities and institutions, to arrange electrical devices, for example, in racks and usually to wire them "floating" at the back of their respective devices. For example, for this purpose, a device plug belonging to the electrical device can be arranged, in particular, at the back of the device, and for its part, on the connection side, for example, connected in an electrically conductive manner to a circuit board of the corresponding electrical device. Subsequently, the device plug can be connected in an electrically conductive manner to other electrical devices of the device network via a cable plug connector to which at least one cable is connected on the plug side, for example, for signal transmission. In particular, at least two, in particular exactly two cables can be connected to the cable plug connector. If one of the electrical devices is removed from the network, the wiring must currently also be changed, which is disadvantageous. Rewiring not only results in an undesirably high manual effort, but also in new sources of error, for example due to human errors, for example due to errors of thought, carelessness and / or lack of knowledge, for example due to lack of documentation. In addition, this results in a high level of manpower expenditure, since competent personnel must carry out or at least supervise the rewiring. Summary of the invention

[0007] The object of the present invention is to reduce the manual and / or human effort required for removing electrical devices from an electrically wired device network and / or for inserting them into the device network.

[0008] This object is achieved by the respective subjects of the independent claims.

[0009] The electrical switching plug connector system has at least one device plug connector, which has a connection housing for fastening in or on an electrical device. The device plug connector has a plurality of device terminals on the connection side and a plurality of plug contacts on the plug side that are electrically conductively connected to each device terminal.

[0010] In addition, the electrical switching plug connector system has at least one cable plug connector that can be plugged into the device plug connector in the plug-in direction. The cable plug connector has a cable plug connector housing, which has at least one cable output. In addition, the cable plug connector has a plurality of mating contacts, which can be plugged into a respective plug contact of the device plug connector on the plug-in side, so that they can be electrically connected to the corresponding plug contact of the device plug connector. The mating contacts each have a cable terminal on the connection side.

[0011] The switching plug connector system has at least one electrically conductive switching bridge.

[0012] The at least one switching bridge is at least partially arranged in or on the cable connector housing of the cable connector in order to respectively connect two of the mating contacts of the cable connector to one another in an unplugged state in an electrically conductive manner.

[0013] In this case, the term “plugging direction” in the sense of a mathematical motion vector relates to the direction of the plugging process and not to the orientation of the motion vector.

[0014] A particular advantage of the invention is that the cables connected to the respective cable terminals of two mating contacts which are electrically connected to one another via the switching bridge are electrically conductively connected to one another in the unplugged state.

[0015] A particularly great advantage of the invention is that electrical devices can be removed from the network without subsequently having to change the wiring. In particular, the signals that have already passed through the removed electrical device, in particular according to a prescribed data transmission protocol, can now - depending on the design in terms of signal technology - be simply forwarded in the cable connector from one cable to another and thus to the next device in the chain.

[0016] By cleverly planning the cabling and the routing of switching bridges and cables at once, different functions can be implemented in the manner described using the system network.

[0017] In a preferred embodiment, the electrical switchable plug connector system is configured to disconnect the electrical connection of two mating contacts in each case in the plugged state. The two mating contacts are thus galvanically disconnected in the plugged state.

[0018] In a preferred embodiment, the switching bridge is formed from an electrically conductive material, in particular a metal, such as a metal sheet. Therefore, the switching bridge can be a stamped and bent part.

[0019] The cable connector housing and / or the cable connector housing can consist of an electrically insulating material, for example plastic or ceramic.

[0020] In a preferred design, the cable connector housing has at least two cable openings. Thus, in addition to the first electrical device, the cable terminal connector can be connected to two other electrical devices on the cable terminal side, namely, a second electrical device having a second device connector and a third electrical device having a third device terminal connector, the cable terminal connector being connected to the device connector of the first electrical device on the plug side. The connection can preferably be made via a second cable terminal connector and a third cable terminal connector, which are plugged into the second device terminal connector and the third device terminal connector, respectively. Thus, the device network can also be constructed and changed very flexibly for additional fourth, fifth, sixth, ..., nth devices, and in particular without requiring a large amount of effort to expand.

[0021] In a further preferred embodiment, at least one plug contact of the device plug connector can be a blade contact.

[0022] In another preferred embodiment, the mating contact of the cable plug connector is implemented as a fork contact. Therefore, the mating contact has two elastic insertion tongues, which are particularly configured to electrically and mechanically contact the above-mentioned blade contact on both sides.

[0023] In a preferred embodiment, at least one switching bridge, ie each of the switching bridges, is arranged at least in sections between two insertion tongues of two mating contacts.

[0024] This can mean, for example, that the mating contact is arranged and implemented so that the outer insertion tongue of each insertion tongue pair relative to each other insertion tongue pair contacts the switching bridge in the unplugged state, so that the two mating contacts are automatically connected to each other in an electrically conductive manner in the unplugged state, and are automatically separated from each other in the plugged state. That is, in the plugged state, the two outer insertion tongues are bent outward by introducing corresponding blade contacts. Thus, the two mating contacts are electrically separated from each other. A substantially planar switching bridge is sufficient for this arrangement with respect to its geometry. In the case described, the switching bridge can even be completely - and not just partially - arranged between the two outer insertion tongues.

[0025] However, the above-described embodiment also includes an arrangement in which at least one switching bridge is bent, for example, in a U-shape and arranged with its ends between the two plug-in tongues of a plug-in tongue pair, so that the two plug-in tongues of each of the two plug-in tongue pairs are respectively contacted mechanically and electrically. As a result, the conductive properties of the connection in the unplugged state are improved, i.e. the conductivity of the electrical connection between the two mating contacts can be twice as high in the unplugged state as in the above-described variant, since the actual contact surface is approximately doubled. In this case, the plug-in tongue is only arranged in sections between the two outer plug-in tongues.

[0026] In a preferred development, the cable connector has at least one component that is movable relative to the mating contact, on which at least one switching bridge is held.

[0027] This means that the cable connector can have one such movable part, but also a plurality of such movable parts. At least one of the switching bridges is held at the movable part / each of the movable parts. Thus, this can be one switching bridge or also a plurality of switching bridges, for example 2, 3, 4, 5, 6, ... n switching bridges.

[0028] Furthermore, in a preferred embodiment, a single movable part can be provided in the cable connector housing, wherein only one switching bridge is held at the movable part. This is meaningful, for example, for unipolar signal or energy transmission. The switching bridge can be moved relative to the mating contact and electrically contact the mating contact so that they are electrically connected to each other in the unplugged state or the connection is disconnected in the plugged state. To this end, during the plugging process, the device connector can move the movable part so that the electrical connection between the two corresponding mating contacts is disconnected. If the plug connection is disconnected again, the movable part moves back to the initial position again and the electrical connection between the two mating contacts is established again.

[0029] There may be a single movable component on which a plurality of switching bridges, for example 2, 3, 4, 5, . . . n switching bridges, are held.

[0030] A plurality of movable parts can also be present in the cable connector housing, each of which holds only one switching bridge.

[0031] However, a plurality of movable parts may also be arranged in the cable connector housing, on each of which a plurality of switching bridges, but not all switching bridges, are arranged.

[0032] By means of the plugging process, the movable part and thus also the switching bridge held therein can be removed from the mating contact in a spring-loaded manner, in particular. This can be done in the separation direction. The separation direction can, for example, extend parallel to the plugging direction, for example in that the movable part has a slide. The separation direction can also extend perpendicularly to the plugging direction, for example in that the movable part is implemented in the form of a rocker and / or a lever. Thus, by plugging the cable plug connector with the device plug connector, at least one switching bridge held at the at least one movable part can be removed from the corresponding mating contact in a spring-loaded manner in the separation direction. This can correspond to the above-mentioned process in which the conductive connection of the two mating contacts is removed.

[0033] However, "removable" also means that the distance to the corresponding mating contact is increased by "removing". The device thus also has the advantage that a particularly large air gap can be maintained between the switching bridge and the mating contact, so that the device is particularly suitable for high voltages. Furthermore, hybrid forms are also conceivable, in which, although the electrical separation is achieved via deformation of the mating contact, the desired air gap and / or creepage distance is largely generated by the movement of the movable component.

[0034] In a preferred embodiment, the movable part can have at least one spring element. This can be molded onto the movable part, for example, especially when the movable part is made of a sufficiently elastic plastic. This has the advantage of inexpensive manufacturability. In addition, the spring element can apply a particularly advantageously oriented force vector in the manner described - according to the overall arrangement. Alternatively or in addition, at least one spring element can be provided at the movable part. The latter spring element can be a separate spring element, for example a metal helical spring. This has the advantage that the material of the movable part does not have to have the elasticity required for the spring properties.

[0035] The development can therefore otherwise be completely identical to the above-described embodiment in which at least one switching bridge is arranged at least in sections between two insertion tongues of two mating contacts.

[0036] Finally, the increase in the distance between the switching bridge and the corresponding contact has the advantage that the air gap is particularly large. In addition to the above-mentioned configuration, this can also be advantageous.

[0037] For the flatly constructed construction, it is advantageous that the separation direction extends in the plug-in direction, because then the space present in the cable plug connector housing can be better utilized. This can be important if many device plug connectors are provided in a small space.

[0038] It is advantageous if the disconnection direction runs perpendicularly to the plug-in direction, since the fork contacts are subject to less wear in this way.

[0039] In a further advantageous embodiment, at least one switching bridge can have two contact surfaces which lie opposite one another.

[0040] In an unplugged state, the switching bridge can respectively make electrical and mechanical contact with the two insertion tongues of each of the two mating contacts electrically connected via the switching bridge, in that each of its two mutually opposite contact surfaces makes mechanical and electrical contact with each of the two insertion tongues of each mating contact.

[0041] In particular, the switching bridge can be designed to be essentially flat.

[0042] The switching bridge can be designed as a one-piece stamped or bent stamped part and preferably consists of sheet metal.

[0043] In a preferred embodiment, each of the two plug-in tongues of two mating contacts electrically connected via the switching bridge has a respective switching contact section which is in electrical and mechanical contact with the respective switching bridge in the unplugged state.

[0044] The device wiring device is suitable, for example, for electrically connecting at least three and in particular also more than three electrical devices, namely 4, 5, 6, 7, . . . n electrical devices, but at least as already mentioned, for electrically connecting three devices, namely a first electrical device, a second electrical device and a third electrical device.

[0045] Here, the device wiring device has a plurality of cables and a switching plug connector system of the above type. At least one first device plug connector of the device plug connectors belongs to a first electrical device, i.e., the first device plug connector is fastened in or on the first electrical device, for example, with its connection housing, and is electrically connected to the electrical device with its device terminals, for example, with electrical printed conductors of a circuit board of the electrical device.

[0046] The cable plug connector plugged with the first device plug connector is respectively connected or at least connectable to the second electrical device and the third electrical device via at least one of the cables. This can be done in particular via other device plug connectors and cable terminal plug connectors at the corresponding electrical devices.

[0047] Thus, by means of the connection, in the plugged state, the first electrical device is automatically connected in an electrically conductive manner not only to the second electrical device but also to the third electrical device. In contrast, in the unplugged state, the second electrical device and the third electrical device are automatically connected in an electrically conductive manner to each other and are automatically electrically disconnected from the first electrical device. Finally, in the unplugged state, the switching bridge already electrically connects the two cables connected to the corresponding mating contacts in the cable connector.

[0048] As has already been indicated, the device wiring arrangement described here for only three electrical devices can be expanded to any number of possible electrical devices.

[0049] Advantageous embodiments of the invention are specified in the dependent claims and in the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Several embodiments of the present invention are shown in the drawings and are explained in detail below. The drawings show:

[0056] Figures 6a to 6i The plug connector system is shown in a fifth embodiment. DETAILED DESCRIPTION

[0057] The drawings contain partially simplified schematic diagrams. In some cases, the same reference numerals are used for identical, but possibly unequal, elements. Different views of the same element may be scaled differently. Directional indications, such as "left", "right", "upper" and "lower", are to be understood with reference to the corresponding drawings and may vary in the individual figures relative to the objects shown.

[0058] Figure 1a The device wiring arrangement is shown, which is composed of a plurality of cables 100 and a plurality of cable plug connectors 1, 1', wherein one of the cable plug connectors 1' has a switching bridge 33. In addition, three electrical devices 41, 42, 43 are shown, namely a first electrical device 41, a second electrical device 42 and a third electrical device 43. A device plug connector 2 is provided at each of the devices 41, 42, 43 and is electrically connected to the electronic devices of the corresponding electrical devices 41, 42, 43 on the connection side.

[0059] One cable connector of each of the cable connectors 1 , 1 ′ of the appliance wiring arrangement is plugged into each appliance connector 2 .

[0060] In the cable plug connector 1' shown in the middle, the switching bridge 33 is disconnected. The cable plug connector 1' is connected to each of the two other cable plug connectors 1 via a cable 100. Therefore, the second electrical device 42 is connected to the first electrical device 41 (shown in the middle) via the device wiring device. In addition, the third electrical device 43 is connected to the first electrical device 41 via the device wiring device. However, the second electrical device 42 and the third electrical device 43 are not directly connected to each other, but are connected only via the first electrical device 41 if necessary, if the first electrical device 41 is set to establish a signal flow between the two other electrical devices 42, 43.

[0061] exist Figure 1b 2 shows how the device connector 2 of the first electrical device is separated from the cable connector 1 ′. The switching bridge 33 is automatically closed, so that the two further electrical devices 42 , 43 are automatically connected to one another in an electrically conductive manner via the device wiring arrangement.

[0062] Figure 1c and Figure 1d Show Figure 1a The enlarged portion is shown in the figure and is for overview only.

[0063] Figure 2a to Figure 2e The plug connector system is shown in a first embodiment.

[0064] As in Figure 2a As shown in FIG. 1 , the cable connector 1 ′ has a cable connector housing 14 and can be plugged into a device connector 2 in a plug-in direction S. The device connector 2 has a device connector housing 24 .

[0065] exist Figure 2b In the diagram, the device connector housing 24 is shown transparently and the cable connector housing 14 is removed. This allows for observation of the mating contacts 12 of the cable connector 1 ′, which can be plugged into the plug contacts 21 of the device connector in the plugging direction S. The orientation of the arrow of the plugging direction S is selected here from the subjective perspective of the cable connector, and the reference symbol S represents the direction of movement, but not the orientation of the movement vector.

[0066] Here and in Figure 2c 1 , the cable connector 1 ' can be seen from different perspectives without the housing 14. At least one movable part 3 of the cable connector 1 ' is shown here. The movable part 3 has a slide 34 with an actuating section 341, which interacts with the device connector 2 during the plugging process. The cable connector also has at least one spring element 35, in this case four individual spring elements 35 designed as helical springs.

[0067] In another embodiment clearly belonging to the disclosure of the present invention, the spring element can also be molded onto a movable part, especially a slide. For this reason, the slide can be made of fully elastic plastic, and the elasticity of the spring element can also be realized by its shaping.

[0068] A switching bridge 33 is respectively fastened to the slides 34 .

[0069] In the unplugged state, the switching bridge bears against the switching contact section 123 of the mating contact 12 to be electrically connected / bridged due to the spring force of the spring element.

[0070] Figure 2d and Figure 2e The device connector 2 and the cable connector 1 ' are shown in the plugged state. Here, for example, contact pins 21 that are not required for current transmission abut against the actuating section 341 and push the corresponding slide 34 away from the device connector in the disconnection direction T against the spring force. Here, the switching bridge 33 is disconnected from the switching contact section 123. The bridge is thus automatically removed in the plugged state. Here, the disconnection direction T runs parallel to the plugging direction S.

[0071] exist Figures 3a to 3d A second embodiment of the plug-in system is shown in FIG.

[0072] Each mating contact has two plug-in tongues 121, 122, of which one plug-in tongue 121, 122 (i.e. the two plug-in tongues 121, 122 that are farthest from each other) is electrically conductively connected in the unplugged state via a contact bridge 33 that is designed in a planar manner in this case. For this purpose, the two outer contact tongues 121, 122 each have a switching contact section 123'. The contact bridge 33 is arranged at least in sections between the two plug-in tongues 121, 122, i.e. the switching contact sections of the two plug-in tongues 121, 122.

[0073] During the plugging process, the two outer plug-in tongues 123 ′ are pressed away from each other by the plug contacts 21 of the device plug connector 2 . As a result, the plug-in tongues lose electrical contact with the switching contact section 123 ′ and the electrical bridge is removed.

[0074] The contact pins 21 of the device plug connector 2 are components of the device terminals 20 formed by metal contact elements. The device terminals have a contact pin 21 for welding to the corresponding electrical device 41. Figure 3c Circuit board terminals on the circuit board 60 are shown in FIG.

[0075] exist Figure 3d 1 and 2 show once again the unbridged state in the plugged-in state and the bridged state in the unplugged state. It is particularly evident here that in the unbridged state the distance between the two outer plug-in tongues of the plug-in contact bridge 123 ′ is extremely small.

[0076] Furthermore, a cable terminal 120 with a mating contact 12 is shown here for the first time. The cable terminal has a cage-shaped busbar 10 and a V-shaped clamping spring 11 .

[0077] Figure 4a and Figure 4b A third embodiment is shown, which represents a combination of the first and second embodiments. Here, as in the second embodiment described above, the outer plug-in tongues 121, 122 are also bridged by the plug-in contact bridge 123' in the unplugged state and are moved outwards by the plug-in contact 21 of the device plug connector 2 in the plugged state, so that the bridge is removed.

[0078] However, due to the very small spacing, at least for high voltages, as already mentioned in the above embodiments, the desired air gap cannot be maintained in this way. In order to overcome this problem, as already shown in the first embodiment, the corresponding plug-in contact bridge 123 ′ is fastened to the slide 34. In this case, however, a separate slide 34 is provided for each plug-in contact bridge 123.

[0079] Furthermore, the cable terminal 120 with the cage-shaped busbar 10 and the V-shaped clamping spring 11 can be better seen in this illustration. The disconnection direction T also runs parallel to the plug-in direction S in this case.

[0080] exist Figure 5a to Figure 5d In the fourth embodiment shown in FIG. 3 , the movable part 3 has a rocker 34 ′. By the spring force of the spring element 35 , the plug-in contact bridge 33 held at the rocker 34 ′ is pressed downward in the drawing in the unplugged state, thereby connecting two adjacent mating contacts 12 .

[0081] In contrast, during the plugging process, the sliding bevel 343 of the rocker 34 slides onto the ramp 241 of the device plug connector housing 24, thereby lifting the plug contact bridge 33 upward in the drawing against the spring force, thereby moving the plug contact bridge away from the mating contact portion 12 in the disconnection direction T. Here, the disconnection direction T runs perpendicular to the plugging direction S.

[0082] exist Figures 6a to 6i A fifth embodiment is shown in FIG.

[0083] exist Figure 6a and Figure 6c The device connector 2 and the cable connector 1 ′ and their housings 24 , 14 are shown.

[0084] The device plug connector 2 is soldered to a printed circuit board 60 by means of its device terminals 20 , at the end of which in each case a printed circuit board terminal 26 is located. The device terminals are designed integrally with the plug contacts 21 .

[0085] In the present example, the cable plug connector 1 ′ has four cable openings 140 , through which each cable 100 is guided.

[0086] Figure 6d to Figure 6f The following concept is described, which is different from the second embodiment: Each of the participating insertion tongues 121, 122 has a switching contact section 123". Between the switching contact sections 123" of the insertion tongues 121, 122 of the mating contact part 120, the plug-in contact bridge 33 is electrically contacted on both sides. In addition, as already mentioned in the above example, the plug-in contact bridge 33 is fastened to the slide 34. During the plugging process, the two insertion tongues 121, 122 of the two participating mating contacts 12 are first pressed away from each other by the plug-in contact part 21 of the device plug connector 2, thereby releasing the plug-in contact bridge 33. In addition, the slide 34 is pushed by the plug-in contact part so that the plug-in contact bridge 33 is further away from the mating contact part 12.

[0087] exist Figure 6g to Figure 6i The first separation process is illustrated again in a front view.

[0088] Figure 6g The current 200 is shown through two cables 100 , two mating contacts 12 bridged by the plug-in contact bridge 33 , and through the plug-in contact bridge 33 itself.

[0089] On the cable terminal side, the cable 100 with the insulation stripped off is inserted into the corresponding cable terminal 120 using the so-called “push-in” technique.

[0090] Figure 6h Two mating contacts 12 are shown in the unplugged state, whose plug-in tongues 121 , by means of their switching contact sections 123 ″, make electrical and mechanical contact on both sides with the plug-in contact bridge 33 .

[0091] Figure 6i The plugged state is shown, in which the two insertion tongues 121, 122 press the plug contacts 21 of the device plug connector 2 away from each other. As a result, the two associated switching contact sections 123" lose mechanical and electrical contact with the plug contact bridge 33 and release the plug contact bridge. Figure 6g The current / signal flow 200 shown in FIG. 1 is thus interrupted.
