title

Electrical plug device

The invention relates to an electrical plug-in device with at least one projection, which projects at least partially in the radial direction and is formed along at least part of the circumference. The invention further relates to a connector assembly having a plurality of electrical slots and a plurality of electrical connectors. In addition, the invention relates to an electrical control device arrangement with at least one electrical plug-in device and / or at least one plug connection arrangement.

State of the art

In motor vehicle construction electrical plug devices are often used. In particular, when higher electrical power, higher electrical currents and / or higher electrical voltages are used, sufficient contact protection and / or ensuring or checking a safe plug state is required.

Known in the art connector plates are often provided with locking levers. These have projections which engage behind the connectors in regions and thus ensure a tight fit of the connector. A disadvantage of such connector plates of relatively complex structure and the complex assembly of the plug to the connector plate.

Disclosure of the invention

It is therefore proposed, an electrical plug-in device which projects at least one projection which projects at least in regions in the radial direction and along at least a part of the circumference is formed such that at least parts of the at least one projection are formed asymmetrically. Due to the asymmetrical design, it is possible in a surprisingly simple manner that electrical plug devices can hold or lock each other, or else can be fastened or locked in a simple manner to holding devices. Moreover, it is also possible with the proposed asymmetrical design of the projection that the plug devices can be provided with a certain coding, so that the plug devices (only) can be plugged into suitable places, and in particular can be arranged only in a certain order.

The electrical plug-in devices themselves can be constructed symmetrically or asymmetrically in any desired manner. It is possible, for example, that these circular, oval, rectangular, square, triangular and the like are formed. The electrical plug-in devices can have a single or a plurality of electrical contacts in any desired manner

(For example, 2, 3, 4, 5 or 6 contacts). The electrical plug-in devices can be designed both for small currents (eg for electrical signal lines, measuring signal lines, control power lines, computer signal lines and the like) or else designed for high currents or powers (for example for connecting electric motors, electric generators, accumulators, etc .).

Advantageously, the electrical plug-in devices have a plurality of projections, wherein preferably substantially diametrically opposed to each other and / or at an angle to each other arranged projection pairings are provided. With the proposed embodiment, it is possible, in particular, for electrical plug-in devices to be able to hold or lock one another when they are arranged one behind the other along a row or in another way. Such plug-in connectors arranged along one direction are widespread, in particular in motor vehicle construction, because in this way the slots can be arranged particularly simply along a printed circuit board for electronic components. In addition to a row extending in the longitudinal direction, it is also possible, in particular, to provide a zig-zag row or an arc on electrical plug-in devices arranged one behind the other. The type of arrangement of the electrical plug devices to one another can be based in particular on the space requirements. It can be advantageous if at least two projections and / or at least two projection regions are arranged offset from one another in the axial direction. With such a configuration, a mutual locking of several electrical plug devices can often be realized particularly easily.

It may also be advantageous in particular if a plurality of electrical plug-in devices (at least from their basic structure) are constructed identically. This can in particular make possible simplifications in the production and / or storage of the electrical plug-in devices or their precursor steps. In this context, it should be noted that in many cases an unambiguous assignment of an electrical plug-in device to a corresponding slot often can be done anyway by the special design of the electrical plug-in contact itself.

It can also be meaningful that at least two projections and / or at least two projection regions have at least one fitting element. In this way, it is possible in a particularly simple manner to realize a mechanical coding of the electrical plug-in devices, so that they can be fastened, for example, only on the slot provided and / or can be arranged relative to one another only in a certain permitted order.

A useful embodiment of at least one fitting element may result if it is designed as a recess and / or as a projection, wherein the fitting element is at least partially aligned in the radial and / or axial direction. In this context, it is to think of different geometric shapes, which are formed for example in the form of nose-like projections and / or corresponding recesses. To think here is, for example, circular, triangular, square, square, pentagonal, etc. forms. Also, an appropriate arrangement (for example, longitudinal arrangement) of projections and / or recesses to think, which are designed such that a clear fit may result. For example, protruding pins could be provided at 2, 3, 4 or 5 imaginary coding points each in a different arrangement and / or number. Correspondingly corresponding recesses can be provided on the opposite side. In particular, it is possible - A -

dere to arrange the corresponding fitting elements in the axial direction. In this case, these usually stand out from a plane which is formed by the projection of the electrical plug-in device. It is also possible to provide the corresponding fitting elements in the radial direction, so that the corresponding elements usually on the outside of the corresponding

Projection of the electrical plug device can be located.

It is usually advantageous if the electrical plug-in device is formed with at least one rotation. This makes it possible for the electrical plug-and-socket device to be in one (or possibly several) unique ones

Fix position relative to a corresponding slot or to allow it that the electrical connector can be inserted only in one (or more) defined positions in the electrical slot. As a rule, a better mechanical fit of the electrical plug-in device can thereby be realized, and in particular it is generally possible to realize the operation of the projection (ie in particular the mutual locking of several electrical plug devices with one another) in a clearer, safer and more durable manner. This is especially true when fitting elements are provided.

A particularly useful embodiment may result if the electrical plug-in device has at least one projection which forms a part, preferably a one-piece part, particularly preferably an integral part of an electrical contact protection device for the electrical plug-in device. In this way, a particularly firm and durable seat of the projection can be realized. In addition, the manufacture, storage and manageability of the electrical plug-in device (especially when mounting the electrical plug-in device to a slot) can often be improved. In particular, in the case of a one-piece design of at least one projection with an electrical contact protection, the corresponding part of the electrical

Plug-in device can be produced for example by a plastic injection process, which is usually particularly cost.

Also proposed is a plug connection arrangement which has a plurality of electrical slots and a plurality of electrical plug devices, wherein at least one electrical plug device is provided. is formed according to the structure described above. The connector assembly then has the features and advantages already described in connection with the electrical connector in an analogous manner.

In particular, it may prove advantageous if at least a part of the electrical plug-in device at least partially mechanically block in the connector assembly. In this way, a particularly tight fit of the electrical connector (s) on the slots is possible. In addition, it is possible to prevent individual electrical plug-in devices from being able to be withdrawn, with particular reference to internal electrical plug-in devices. It is also possible, in particular, that the presence of an electrical contact of all plug-in connection arrangements can be realized particularly simply with a single "control instance", namely, in particular when the corresponding "control entity" is located at a suitable end of an electrical plug-in device arrangement. Incidentally, it is also possible for at least one projection of at least one electrical plug connection to also have a corresponding device in connection with at least one electrical slot which holds the plug connection at the electrical plug-in location.

A meaningful development results if at least one mark-up signaling device is provided, which is designed in particular as a switching device and / or signal line plug-in device. For example, a switching head of a switching device can come into mechanical contact with a projection of an electrical plug-in device. Only when the corresponding electrical plug-in device is electrically and mechanically securely seated on the corresponding slot, the switch device closes. Thus, with the help of the switch device via a corresponding control logic, a mechanically fixed seat of the corresponding electrical plug device can be verified. An optionally present mechanical blockage of the electrical plug devices with one another can thereby also be used to verify electrical and / or mechanical secure attachment of at least part of the remaining electrical plug devices. Instead of a switch device, it is also possible that, for example, a signal line plug-in device is formed at the end. If the electrical contact is affected by the corresponding interrupted signal line plug-in device, this is usually a sure indication that the corresponding plug-in device has been removed from the slot. The signal line plug-in device can in any way have a single electrical conductor, or preferably have additional borrowed electrical signal lines, via which corresponding information can be transmitted. For example, the signal line plug-in device may be designed as an electrical multiple plug, such as, for example, as a male connector or as a tab connector known from computer engineering.

Furthermore, an electric control device arrangement is proposed, in particular an electrical control device arrangement for controlling at least one electric motor in electrically operated vehicles and / or hybrid vehicles, in which at least one electrical plug device according to the previous description and / or at least one plug connection arrangement according to the previous description is provided is. The electrical control device arrangement then has the advantages and properties already described in an analogous manner. The electrical control device arrangement may in particular be power electronics. This power electronics can in particular with the appropriate coolant to dissipate the generated

Heat to be provided. In particular, it is also possible to realize a cooling by means of a liquid circulation. For this purpose, in particular in the case of hybrid vehicles, the usually already existing coolant circuit of the hybrid vehicle can be used. Especially with the help of cooling liquid circuits, high heat outputs can be safely dissipated.

Finally, a method for arranging electrical plug-in devices at electrical slots, in particular at an electrical control device arrangement, preferably at an electrical control device arrangement for controlling at least one electric motor in electrically powered vehicles and / or hybrid vehicles, proposed in which at least one first electrical plug-in device at least one second electrical plug device at least partially blocked mechanically. The presently proposed method also has the features and advantages already described above in connection with the electrical plug-in devices, the plug connection arrangement and the electrical control device arrangement in an analogous manner. Of course, it is also possible to further develop the proposed method in the sense of the above description.

In Fig. 1 is a schematic representation of the side seen from a first

Embodiment for an electrical connector 1 shown having two asymmetrically arranged projections 2, 3. FIG. 2 shows the electrical connector 1 shown in FIG. 1 in a schematic view from below.

The projections 2, 3 are integrally formed laterally in one piece on a Berührschutz 4 in the present embodiment. Protrusions 2, 3 and shock protection 4 are made of the same material. For example, the projections 2, 3 and the contact protection 4 may be made of a plastic material, wherein the shaping can be done by a plastic injection molding process.

The shock protection 4 surrounds an electrical connector 5, which is arranged centrally in the shock protection 4. The electrical connector 5 may, as shown in the present case, be designed as a circular connector. However, it is also possible that the electrical connector 5 is formed for example as a flat connector or in any other way. Of course, it is also possible that a plurality of electrical connectors 5 is provided, such as 2, 3, 4, 5, 6 or 7 electrical connectors. The electrical connector 5 is electrically contacted with a cable 6 which leads away from the contact protection 4 in an axial direction A. The cable 6 is surrounded in the presently illustrated embodiment with an electrical protective insulation. Of course, it is also possible that the cable 6 of the e- lektrischen plug 1 is led away at an angle to the axial direction A from the connector portion 7, such as at an angle of 90 °. For this purpose, a deflection device known per se can be used. In particular, in the latter case, the axial direction A then usually refers to the position of the electrical connector 5 in the connector area 7, in other words to the direction in which the electrical connector 1 must be moved to be plugged onto a suitably designed slot , In the present embodiment, however, the cable 6 is connected in the axial direction A to the connector portion 7. In Fig. 1, a strain relief 8 between the cable 6 and shock protection 4 is additionally provided, which ensures a secure and lasting hold of the cable 6 at the connector area 7. Parts of the strain relief 8, in addition to the mechanical support of the electrical

Connector 5 serve.

The two projections 2, 3 are in the illustrated in FIGS. 1 and 2 embodiment of the electrical connector 1 in the axial direction A offset from each other on the contact protection 4. As can be seen in particular Fig. 2, the projections 2, 3, however, otherwise identical. The projections 2 and 3 are arranged on the contact protection 4 so that they protrude from the connector area 7 in mutually diametrically opposite directions. The width b of the projections 2, 3 is usually selected in a range of 5 mm to 10 mm. On the one hand, such a width b proves to be relatively space-saving, on the other hand, the projections 2, 3 can absorb a sufficient mechanical force and, moreover, adequately compensate for bearing tolerances of two adjacently arranged electrical connectors 1 (cf., for example, FIGS. The length l of the projections 2, 3 corresponds approximately to the diameter of the contact protection 4, which surrounds the electrical connector 5. In this way, a plurality of electrical connectors 1 can be arranged in a row one behind the other, without the width of the finished connector row having to increase unnecessarily.

In particular, with special designs, it is of course also possible to use other dimensions. Thus, the width b of the projections 2, 3 may be less than 5 mm, for example, in the case of relatively small plugs 1. Conversely, the width of the projections 2, 3, for example, in power connectors 1, which are formed correspondingly large, quite well be chosen larger than 10 mm.

Furthermore, in the present embodiment, the outer contour 9 of the projections 2, 3 is selected so that a convex outer contour 9 of the connector portion 7 of the electrical connector 1 results. The outer region of the projections 2, 3 runs approximately parallel to the outer contour of the contact protection 4. However, it is also possible for the projections 2, 3 to be an exemplary embodiment. wise rectangular outer contour 9 form. It is also possible that the outer contour 9 of the projections 2, 3 is concave (see, for example, Fig. 11, 12). In this way, the projections 2, 3 can simultaneously serve as a rotation for the electrical connector 1. An advantage of the convex outer contour 9 is that it is relatively space and material-saving.

In addition, the rounded outer contour 9 ensures a lower risk of injury or damage when mounting the electrical connector 1. Also, the selected convex outer contour 9 is relatively tolerant of alignment errors.

In addition to an arrangement of the individual electrical connector 1 in a row one behind the other (see, for example, Figure 9, 10), it is also possible, the individual electrical connector 1, for example, in a zig-zag row 38 (see Figure 11) or along a bend 39th (see Figure 12) to arrange.

For example, to form the zig-zag row 38 shown in FIG. 11, the projections 2, 3 of the individual electrical connectors 1 are arranged at an angle αi 40 relative to one another. The angle αi in the presently illustrated embodiment is αi = 90 ° (the direction of the angle αi alternating).

In contrast, the individual electrical connector 1 in the embodiment shown in FIG. 12 are arranged along a curved line 39. Again, the projections 2, 3 of the individual electrical connector 1 are arranged at an angle Ci ₂ 40 to each other. The size of the angle α ₂ 40, however, is different and, in the exemplary embodiment shown in FIG. 12, is α ₂ = 135 °. Of course, the size of the angle depends in particular on the radius of the arcuate arrangement 39 of the individual electrical connector 1.

In Fig. 3 and Fig. 4 is another embodiment of an electrical

Plug 10 shown. 3 shows the electrical connector 10 in a schematic view from the side. Fig. 4 shows the opposite the electrical connector 10 in a schematic view from below. In this case, in Fig. 4 in Figs. 4a; 4b, 4c each show different Ausgestaltungsmög- possibilities of axially aligned fitting elements (projection 13 and receiving opening 14). The electrical connector 10 shown in FIGS. 3 and 4 is similar in many areas to that shown in FIGS. 1 and 2 electrical connector 1. In contrast to this, however, the projections 1 1, 12, the contact protection of the plug part 7 4th In addition, a projecting pin 13 (or a plurality of protruding pins 13c, see Fig. 4c) and a receiving opening 14 (or a plurality of receiving openings 14c, see Fig. 4c) are provided. The protruding pins 13 and the receiving openings 14 are provided on mutually facing sides of the projections 1 1, 12. This applies in particular to the case in which a receiving opening 14 is formed as a blind hole. However, it is also possible that one or more receiving openings 14 are formed as continuous holes. In principle, however, it is irrelevant on which projection 11, 12 the protruding pin 13 or the receiving opening 14 is provided. The protruding pin 13 can therefore not only - as shown in Fig. 3 - at the, facing away from the plug-in area

Projection 1 1 are provided, but also at the, the plug-in area facing projection 12. The receiving opening 14 is then provided in each case corresponding, other projection 11, 12.

In FIG. 4, 4a, 4b, 4c each have different examples in the subfigures

Training opportunities for the protruding pins 13 and the receiving openings 14 shown.

Thus, in FIG. 4 a, the protruding pin 13 a, which is arranged approximately centrally on the first projection 11, has a circular cross-section. In contrast, the receiving opening 14a, which is formed in the second projection 12 of the electrical connector 10a shown in Fig. 4a, a square cross-section. Due to the different cross-sectional shape of protruding pin 13a and receiving opening 14a, two electrical plugs 10a, which are of similar design (that is, for example, two electrical plugs according to Fig. 4a) are not "contacted" with each other (see Fig. 9, 10) This way, it can be effectively prevented that a plurality of electrical connectors 10a are plugged, for example, in the wrong order on a corresponding connector strip. It is of course also conceivable that the projecting pin 13a and the receiving opening 14a have a similar cross-section. In this case, the corresponding electrical connectors 10a can be contacted with each other as desired. The Vertauschchsicherheit can then - if necessary and / or desired - be realized in different ways, such as by using different shaped electrical connector 5 and / or by using a different number and / or location of the electrical connector 5. Nevertheless, by the provision of protruding pins 13 and / or receiving openings 14, for example, in an advantageous manner an anti-rotation and / or a particularly strong mechanical bond can be realized.

In Fig. 4b, a structure is shown, which is very similar to the structure shown in Fig. 4a. Only the cross-sectional shapes of the projecting pin 13b and the receiving opening 14b are designed differently with respect to the example shown in FIG. 4a. Thus, in the electric plug 10b shown in Fig. 4b, the protruding pin 13b is provided with a square cross section, whereas the receiving opening 14b is provided with a triangular cross section.

By the mutually corresponding configuration of the projecting pin 13b of the electrical connector 10b shown in Fig. 4b and the receiving opening 14a of the electrical connector 10a shown in Fig. 4a, the two electrical connectors 10a, 10b are contacted with each other. A plug arrangement 10a-10b is thus an admissible plug arrangement, whereas, for example, a plug arrangement 10b-10a is not permissible.

FIG. 4c shows a coding option which can be used alternatively or additionally to the coding option illustrated in FIGS. 4a, 4b. In the present case, several areas 15 are provided in the projections 1 1, 12

(In Fig. 4c shown by dashed lines) in which protruding pins 13c and receiving recesses 14c can be provided. By corresponding provision or non-provision of pins 13c or receiving recesses 14c, a specific connector sequence between electrical connectors 10c can be allowed or prevented. FIGS. 5, 6 show a further possible design of an electrical plug 16. This, too, is similar to the electrical plugs 1, 10 already described. In the embodiment of the electrical plug 16 shown in FIGS. 5, 6, an edge toothing 19, 20 is provided in each case in the region of the projections 17, 18. The edge toothing 19, 20 in each case has one or more projecting lugs 20 and one or more groove-like recesses 19. Analogous to the exemplary embodiment shown in FIG. 4c, a plurality of regions 21 are provided (indicated by a dashed line in FIG. 6) in which a respective groove-like recess 19 or a projecting nose 20 can be provided or not. By an appropriate combination of groove-like recesses 19 or protruding lugs 20, an allowable sequence of electrical plugs 16 can be made possible, or a forbidden sequence can be prevented.

Incidentally, the provision of edge toothings 19, 20 can, of course, be realized not only as an alternative but also in addition to the option shown in FIGS. 3 and 4, using protruding pins 13 or receiving recesses 14.

FIG. 8 shows by way of example that an electrical plug 22 within its contact protection 4 can certainly also have a plurality of electrical plug connectors 5. In the embodiment shown in FIG. 8, two electrical connectors 5 are shown, each with a round cross-section. As already mentioned, however, a different number of electrical connectors 5 can be provided. Also, the geometry of the connector 5 may differ from the embodiment shown in Fig. 8. Also, the geometries of the individual electrical connector 5 may well differ at least partially from each other.

The electrical connector 2 shown in Fig. 8, due to its electrical connector 5 and a twist protection. When plugged in electrical connector 22 this can not be twisted. Also, the electrical connector 22 can be plugged only in defined positions on the plug-in area. However, it is possible in the geometry shown in FIG. 8 that the electrical connector 22 can be plugged in a position rotated through 180 ° onto the corresponding plug-in area. This can be, for example be prevented by a suitable number, shape and / or location of the electrical connector 5 also.

In Fig. 7, another electrical connector 23 is shown in a schematic view from below. Also, this electrical connector 23 is similar to the already presented electrical connectors 1, 10, 16, 22. However, the electrical connector 23 shown here is additionally in the field of Berührschutzes 4 with a mechanical rotation 24, which in the present case in the form of a groove-like projection 24 on the inside of the contact protection 4 is provided. The anti-rotation 24 causes not only a rotation of the plugged plug, but also a correct position plugging the electrical connector 23 to a corresponding connector area.

In Fig. 9, a first embodiment of an electrical control device 25 is shown in a schematic plan view from the side. The electrical control unit 25 is widely a housing 26, in which, for example, an electronic control circuit is arranged, which serves to control the electric motor or the control of the electric generator in a hybrid vehicle (depending on driving condition). The electronic control circuit is provided with corresponding power semiconductors for this purpose. The power semiconductors generate at

Operation of the control circuit, a certain waste heat, which is dissipated in the present embodiment via the coolant circuit of the hybrid vehicle. Serve coolant ports 27, which are provided on the electronic control unit 25.

On the lid 28 of the electronic control unit 25, an electrical contact strip 29 is provided. The electrical contact strip 29 has a power connector region 30, on which a plurality of electrical power connectors 32 are plugged. Furthermore, the electrical contact strip 29 has a control plug region 31, to which electrical control lines, electrical signal lines, etc. are supplied to the electrical control device 25. In the embodiment of the electrical control unit 25 shown in FIG. 9, a flat plug 33, which is similar to flat plugs known from its basic construction, serves as for example in the computer field. The electrical power connectors 32 are each provided with two projections 2, 3. Also, the tab 33 has a projection (in the present case, however, only a single projection 2).

The position, the arrangement and the formation of the projections 2, 3 and the electrical power connector 32 and the tab 33 can be carried out according to the training possibilities shown in FIGS. 1 to 8.

As can be seen in FIG. 9, a first one engages in the plugged state of the electrical power connector 32 and the tab 33

Projection 2 the corresponding second projection 3 of the respective adjacent electrical connector 32, 33. In this way, it is not possible in the embodiment shown in FIG. 9 to withdraw one of the electrical power connector 32, without causing the tab 33 is released. In the flat cable 34 of the tab 33, however, a line is provided which is designed as a control line, such that when an interruption of the control line by a suitable control electronics, the electric power connector 32 and / or the power plug contacts 30 of the electrical contact strip 29 are switched dead. In this way, a very high contact security can be realized with simple means. When the projections 2,

3 is additionally formed with a "coding" analogous to the exemplary embodiments of the electrical connector in FIGS. 3 to 6, a correct sequence of the electrical power connectors 32 can also be ensured when plugging them onto the electrical control unit 25. In particular, it is also possible , on the cover 28 and on the electrical contact strip 29 a

Provide end projection 35 having a suitable receiving opening 14 (see Fig. 3, 4). It is also possible, the end projection 35 in such a way that it can cooperate with a peripheral toothing 19, 20 according to the embodiment of an electrical connector 16 shown in Fig. 5, 6. Above all, the correct plugging on of the first electrical power plug 32 can be checked by means of such an end projection 35, without an incorrect attachment occurring, for example, only later when plugging in a later electric power plug 32 and / or only at the very end when plugging in the flat plug 33. However, the end projection 35 may also be omitted, in particular if the projections 2, 3 of the electrical connector

32, 33 have no coding. In Fig. 10, another electrical control device is shown in a schematic view from the side. The electrical control device 36 shown here is similar in its basic structure to the electrical control device 25 shown in FIG. 9.

In the illustrated embodiment of the electrical control unit 36, however, the electrical contact strip 29 on the cover 28 of the housing 26 has only one power plug region 30. On this three electrical power connector 32 are attached in the present case. The electrical power connectors

32 are - analogous to the embodiment shown in FIG. 9 - each provided with projections 2, 3. In order to check the correct fit of the electric power plug 32 (in FIG. 10 on the right side) and also the remaining electrical power plug 32 via the latching of the projections 2, 3, a control switch 37 is provided on the housing cover 28. If the control switch 37 is pressed down by the projection 3 of the right-hand electrical power plug 32, the electronic circuit of the electronic control unit 36 is signaled that the electric power plugs 32 are correctly plugged onto the power plug region 30. The electrical voltage is released accordingly.

The supply of the electrical control signals, measuring signals, etc. takes place in the embodiment of the electrical control unit 36 shown in FIG. 10 via a ribbon cable 34, which is provided with a flat plug 33. The flat plug 33 is placed on a control plug portion 31, which in the present case on the side of the

Housing 26 of the electrical control unit 36 is formed, plugged. However, the position of the control connector portion 31 can be arbitrarily selected, such as at the front, back and / or bottom of the electrical control device 36. Optionally, it is also possible to provide no control connector portion 31.
