Electrical plug element

The present invention relates to an electrical plug ^¬ element for a plug-in module, and the plug-in module itself. Such a plug-in module can be used in conjunction with a motor unit, in particular a Versteilmotor used, for example, for moving windows, doors, flaps or covers.

Modern motor vehicles today have power-operated devices for moving (opening or closing) window panes. Such devices include a motor unit as Versteilmotor which is provided in a motor vehicle door by means of a transmission device and according to cables for moving the window. The assembly process in motor vehicles usually requires a modular design of the individual components, such as those of a power window device. A module is formed by the motor unit, which may have both a motor and a corresponding transmission in a housing, wherein a second module, which may be formed as a plug-in module for power supply and control of the electric motor with the module of the motor unit is connectable. For supplying the engine with electrical energy or with electric current electrical Kon ^¬ clock elements are arranged in the housing or module of the motor unit of the need ^¬ A shear modulus are electrically connected to corresponding contacts of the motor plug-in module at a dumping. If the plug-in module does not have precise guidance, which can only be achieved in practice with great effort, then, due to a corresponding movement play of the plug-in module, an introduction into the housing or module of the motor unit can only be carried out with great difficulty and with repeated attempts if the device is used for electrical contacting Motor contacts of the plug-in module with the electrical contacts of the motor unit a reliable connector should be achieved. Thus, it is the object of the present invention to provide a possibility with which a reliable contact, in particular in the context of a plug connection between a plug-in module and a motor unit to be connected thereto can be produced.

This object is achieved by the subject matter of the independent claims to ^¬. Advantageous embodiments are the subject of the dependent claims.

According to a first aspect of the invention, an electrical plug element for a plug-in module is provided, which is used for connection to a motor unit, in particular a Versteilmotor of a motor vehicle. In this case, the electrical plug element has a fixing section for holding or fixing the plug element. In particular, it can be introduced in a designated carrier element in ver ^¬ application intended use in the insert module. Preferably, the carrier element has a recess into which the electrical plug element is pressed, wherein it is then held on the fixing section. The electric plug member further has a (terminal) contact portion for engaging with a corresponding connector of the motor unit in a mounting direction to make an electrical connection. The contact portion may have a contact portion-side axis which is parallel to the mounting ^¬ direction. Further, the electric plug member has a position alignment portion that connects the fixing portion and the contact portion, and is configured to allow movement of the contact portion in a direction perpendicular to the mounting direction and the contact portion side axis, respectively. Here, the positional alignment portion to ^¬ least two webs that connect the fixing portion with the Kon ^¬ clock section and of which at least one of the webs has a deformable portion which vertically extendable for movement of the contact portion in a direction to Monta ^¬ court tung or together compressible is. In other words, one of the at least two webs is connected to the malleable section changeable in length. In particular, a deformation of the deformable portion can be made such that its length is deformed parallel to the mounting direction. This training of the bearing section of the electric

Plug element has the advantage that the plug element is suitable to ensure a balance of mounting tolerance when used in the plug-in module when connecting to the motor unit, so that even if not properly merge the contact portion with the corresponding connector of the motor unit damage the Kontaktab ^¬ cut and a possible loss of function of the plug-in module is prevented. This is made possible by the adaptability of the position ^¬ alignment section, which allows movement of the contact portion of the electrical connector element in a direction perpendicular to the mounting direction, so

To compensate for misalignment of the corresponding motor unit side connector. Furthermore, the connection of the fixing section to the contact section by at least two webs of the bearing section guarantees a high current carrying capacity of the entire electrical plug element, since the available cross section for the power line despite the movable or deformable design remains large, in particular larger than if only one web would be used for connection.

According to one embodiment of the electrical plug element, the deformable section is meander-shaped on at least one of the webs of the position alignment section and has, for example, an S-shape. Such a configuration of the deformable portion is easy to implement and with little effort and allows good deformability of the ver ^¬ mouldable section. In general, and in particular in this embodiment in a meandering or S-shape, the deformable section may also be formed as an elastically deformable section. The meandering or S-shape allows a spring action, so that misalignment can be compensated reliably during assembly. However, it is also conceivable the deformable portion in a different form than the Form meandering, for example in a zig-zag shape (in the simplest case in a V-shape), so that the geometric dimension or length is expandable and / or reducible. According to a further embodiment of the bearing portion of

Plug member, at least a first of the at least two webs of the bearing portion has a deformable portion, wherein a second of the at least two webs has no such deformable portion. In particular, the second of the at least two webs is aligned in the direction of the mounting direction or the contact-section-side axis. This means that this second of the at least two webs is not deformable in the mounting direction, and thus the electrical connector element, when the plug-in module on or in the motor unit with the motor unit side connectors in contact, entails a certain rigidity. This is important if the motor unit-side connector does not properly meet the contact portion of the electrical connector, as this then an unwanted deformation of the electrical connector occurs.

By contrast, the second of the at least two webs has a Ge ^¬ steering portion, which allows pivoting of the at least one second web and thus the associated contact portion in a direction perpendicular to the mounting direction (and perpendicular to the axis of the contact portion). In this case, the Ge ^¬ steering portion may be provided in particular directly on the fixing of the electrical connector, for example, as an area with a reduced cross-section compared to the further course of the web towards the contact portion. In this way, despite a certain rigidity in Monta ^¬ direction a relatively small force to move the contact portion in the direction perpendicular to the mounting direction required, so that even with misalignment during insertion of the plug-in module in the motor unit or a housing thereof only small forces for assembly needed. According to a further embodiment, the electrical

Plug element formed as a stamped part, in particular as a flat punched part. It may be present as a sheet metal part may be formed at ^¬ play, in a copper-wrought alloy. The ability to form the electrical connector element as a stamped part, the process and device complexity in the production of the connector element, and thus the cost can be kept low. According to a further embodiment, the deformable portion of a web of the position alignment portion, a ge ^¬ ringere flexural strength than the contact portion. In this way, in an alignment error when the contact portion with a corresponding connector of the motor unit, the contact portion is not deformed, but the force causing deformation is directed to the deformable portion of a web of the Lageausrichtungsabschnitts so that it deforms and a movement of the contact ^¬ section causes.

According to a further embodiment, the contact portion has a base web, from which two opposite spring webs (contact webs) go out, the end form a Kon ^¬ contact point, while a respective web is connected at its inner end to the base web. In particular, a respective spring bar has a thickness transverse to the mounting direction, which is less than the thickness of the base web transversely to the mounting ^¬ direction. In this way, a deformation-causing force can be taken in case of improper contact between the contact portion on a corresponding connector of a motor unit of the respective spring bars, so as to prevent unwanted deformation of the entire electrical connector element. Due to the deformation of the Fe ^¬ derelements such alignment errors, however, are compensated again.

In particular, by the formation of the contact section in the form of two spring webs, which thus at two points with the corresponding Speakers can contact the motor unit in order to establish an electrical connection, a high current carrying capacity can be achieved. Furthermore, the particular embodiment of the Lageausrichtungsab- section that allows movement of the contact portion perpendicular to the mounting direction, that in a misalignment of the contact portion can adapt to the "wrong" position of corre sponding ^¬ connector of the motor unit, so that always ensured that both spring bars in conjunction with the corresponding connector of the motor unit in

Stay in contact. According to one embodiment of the contact portion, the contact point is formed by opposing beads projecting from each of the spring bars to each other and the clear distance between the beads in the region of the contact point is less than the extension of Ge ^¬ genkontakts the corresponding connector of the motor unit transverse to the mounting direction , In this way, a reliable and stable electrical contact is made possible. According to a further embodiment of the contact portion, the spring bars between the contact point and its free ends form a contact funnel. Through this funnel ensures that a "wrong" positioned connector of a motor contact hits when striking the spring bars during assembly on the funnel inner side and thus move the spring webs or the contact portion in advancing the contact portion in the mounting direction in a direction perpendicular to the mounting direction or Thus, a "hook" during assembly is avoided.

According to a further aspect of the invention, a plug-in module is provided for connection to a motor unit, in particular with a Versteilmotor. Such a Versteilmotor can be used to move an adjustable element of a motor vehicle, such as Versteilmotor for a power window device. In this case, the plug-in module has a connecting portion for mechanically connecting the plug-in module in a housing with the motor unit. It has further ^

at least one electrical connector element according to the above Erläu ^¬ sion or an embodiment thereof for electrically contacting a corresponding complementary connector of the motor unit. In particular, the plug-in module has an electrical connector according to the above illustration or embodiment thereof.

According to a further aspect of the invention, an adjusting device for a motor vehicle, in particular a window device is provided. In this case, the adjusting device has a motor unit for the power-operated moving of a vehicle-side movable element, such as a window, a flap, a hood or a door, generally for closure elements of openings of the passenger compartment. It also has a plug-in module according to the above illustration or an embodiment thereof for connection to the motor unit in order to supply power to the motor unit and, if necessary, also to control the operation with respect to speed and direction of movement.

In this case, advantageous embodiments of the electrical connector element are applicable to the plug-in module or the Vers ^¬ dividing device as far as to be regarded as an advantageous embodiment of the plug-in module or the adjustment, and vice versa.

Reference is first made to FIGS. 1, in which a perspective view of a plug-in module ESM according to an embodiment of the invention is shown in a perspective view from a viewing direction from above. More specifically, Figure 1A shows the plug-in module ESM substantially from a view from above and behind (with focus on a connector body ASK or a fitting AST), while Figure 1B shows the plug-in module ESM from a view from above and from the front (with focus on a Plug STK or a carrier element TRE of this).

As will be explained in more detail in FIG. 9, the plug-in module ESM is a component which is plugged into a housing MGH of a motor unit ME in order to supply the motor with electrical energy or electrical current. In particular, such adjustment motors are used for moving windowpanes, doors, flaps or covers, generally for closure elements of openings of the passenger compartment.

As main components, the plug-in module comprises a plug STK, which is connected to a connection body ASK. More precisely, a carrier element TRE of the plug and an on ^¬ closing body housing AGH of the connecting body ASK are made of a plastic (preferably injection-molded, and thereby preferably formed in one piece). The production of a one-piece plastic component in the injection molding process is cost-effective and associated with little procedural effort.

The terminal body housing AGH has as a central part a plate-shaped receptacle or a plate-shaped connecting portion VAS, on which fastening bores BBO are formed for fixing the plug-in module ESM in the Motor housing MGH (see Figure 9), preferably a transmission housing of the engine.

From a front side STS of the connecting portion VAS protrudes at a predetermined angle a fitting AST having a substantially rectangular cross-section, which has at its free end a circumferential thin-walled collar BU out. This collar BU surrounds a connection shaft ASS, in which exposed first end sections EA11, EA21 (see FIG. 7) project from electrical contact pins ESK1, ESK2 (and further contact pins) arranged in the connection piece AST or connecting element ASK. These first end portions EA11, EA21 are provided for contacting with a connector, not shown, which is inserted into the connection shaft ASS and while doing, guided by the federal government BU, learns an exact position assignment to the first end portions EA11 and EA21. The connector can be connected to a harness in the vehicle, or emerge from this. In this case, electrical energy or electrical current for operating the motor can be transmitted through this connector on the one hand, as well as control signals, for setting the Bewegungsge ^¬ speed or direction of movement of the motor.

Second end sections EA12 and EA22 of the electrical contact pins ESK1, ESK2 and further contact pins protrude from a front side or second side surface FS2 of the connection section VAS, which are fed in an angled form to contact holes of a printed circuit board LP and are materially contacted (for example soldered) in them it is shown in FIG. The circuit board LP itself is mounted in a manner not shown in the connecting portion VAS and is perpendicular from the second surface or side surface FS2. In this case, the printed circuit board LP fulfills a holding or supporting Function for electronic components EBS, for example a relay RL or a sensor SE.

In a manner not shown, motor contacts or electrical plug elements ESE are also electrically connected to the printed circuit board LP, at least indirectly (see also FIG. 3 in this regard). In particular, these electrical connector elements contact the circuit board by material engagement or are soldered thereto. As will be explained in more detail below, two electrical plug elements ESE are arranged in a respective recess in the carrier element TRE of the plug and fixed in the respective recess via a press connection. As can also be seen in FIG. 3, two exposed contact sections KAB of the electrical plug elements ESE and ESE2 are arranged in the carrier element TRE in such a way that they are offset perpendicularly to a mounting direction RM and from top to bottom in the image plane of FIG are spaced. Electric current or electrical output signals of the push-in module ESM are transmitted to the motor unit ME via these contact sections KAB.

With the insertion of the plug-in module ESM in the motor housing MGH, in which the actual electric motor is rigidly mounted, meet the electrical connector elements ESE, ESE2 on a corresponding complementary, respective stationary mating contact, marked in Figure 9 by the connectors SV1 and SV2. In spite of the dimensional tolerances that are unavoidable in the insertion process over the movement play between the plug-in module ESM and the motor housing MGH to assign a precise location between the electrical connector elements ESE, ESE2 or their contact sections KAB and the complementary mating contacts of the motor unit, the electrical Plug elements designed so that they are in sufficient Perimeter position changes perpendicular to the mounting direction RM of the plug-in module ESM can perform.

To explain this special function of an electrical plug element according to an embodiment of the invention, the electrical plug element ESE is shown in detail in FIGS. In this case, this plug element can be designed in particular as a stamped part made of a metal sheet, for example a copper-wrought alloy.

FIG. 2A shows the electrical plug element ESE in a position in which it is brought into contact with a sheet-like or comb-like counter contact GK in an unloaded state or in a rest position. The counter contact GK should stand for an electrical contact of the motor unit, such as for one of the connector contacts SV1 or SV2 in the housing MGH of the motor unit ME. In the figures 2B and 2C, the electrical connector element is shown in a state in which each movement performs for adjusting an incorrect positioning of the contact GK perpendicular to the mounting ^¬ direction RM, once in one direction in the image plane to the top (Figure 2B) and once down in one direction of the image plane (Figure 2C). The plug element ESE essentially comprises three Hauptbe ^¬ constituents, on the one hand a fixing FAS for holding the male member in the support element TRE, a contact portion KAB for engaging a corresponding plug connector SV1, SV2 of the motor unit, and a position alignment section LAA for connecting the fixing FAS with the contact ^¬ section KAB and the position alignment of the contact portion during the connection of the electrical connector element with a corresponding (incorrectly positioned) mating contact. First of all, the fixing section FAS will be discussed in greater detail. This has a fixing structure TST, which essentially has a Christmas tree structure. In this case, when assembling or assembling the plug-in module, this fixing structure TST, as shown in FIG. 3, is introduced into a holding section HAA of a corresponding recess in the carrier element and pressed with the latter under the action of force. As a result of the pressing operation, the plastic material of the carrier element flows into the interspaces of the projections of the fir-tree-like structure TST, thereby fixing and preventing withdrawal of a plug element ESE from a holding section HAA (upward in the direction in the image plane). The fixing structure TST is (in the image plane in a downward direction) in a Kontaktie- reasoning section LPA, which serves to make electrical contact with the circuit board and the electrical current or electrical energy in the electrical connector element can be ^¬ introduced inserted. In the illustration of FIG. 2 on the respective right side, the electrical plug element ESE has the contact section KAB for contacting a mating contact GK or corresponding plug connector of the motor unit. The contact portion ^¬ KAB comprises a base web 43, at each end, a directed in the mounting direction RM spring bar FEI FE2 and projecting from the. These form between them an (elongated) slot SZ. The webs FEI and FE2, which run parallel to each other initially in the further course (in the direction toward the right in the direction of the free end) in symmetrical arrangement each have an inwardly directed bead W1 and W2. Between these beads a close contact KS is formed. The clear distance between the beads Wl and W2 in the region of the contact point KS is less than the extension E of Ge ^¬ gene contact GK perpendicular to the mounting direction. This feathers the Spring webs FEI and FE2 slightly back (move in a direction perpendicular to the mounting direction away from the mating contact GK) when the mating contact GK passes the contact point KS. For easier feeding of the mating contact GK to the contact point KS, the distance of the two spring webs FEI and FE2 from the contact point KS to the free ends increases again (in the image plane from left to right), so that here a contact funnel KTR is formed.

Now runs, as shown in Figure 2A, the mating contact GK off-center on the contact point KS, so the Ge ^¬ genkontakt off-center hits the contact funnel KTR. In order to allow a secure engagement of the mating contact with the contact point, and to prevent damage to the two components, the electrical connector element ESE has now the position alignment section LAA. This first has a foot FAB, which is connected to the fixing FAS. From the root portion FAB two webs ST1 and ST 2 are provided in a direction from parallel to the mounting direction RM (perpendicular to the orientation of the fixing portion), which ^¬ portion FAS with the contacting portion KAB connect the fixing and of which at least one of the webs, here the web ST1, has a deformable portion VAB. Finally, this deformable section serves to ^permit a movement of the contact section KAB in a direction RU or RD, as shown in ^FIGS . 2B and 2C, perpendicular to the mounting direction. More precisely, the movement or pivoting of the contact section KAB is made possible by the fact that, on the one hand, the second web ST2 has a section between the foot section FAB and the base web BAS in which its cross section occupies a minimum. This section serves as a Ge ^¬ steering section or pivot point GP to achieve a

Swiveling the contact portion KAB around the hinge point GP. On the other hand, the first web ST1 is formed such that it has an area that is expandable or compressible in its length or its dimensions. In particular, it is advantageous if the deformable portion VAB can change its extent in a direction parallel and perpendicular to the mounting direction in order to follow the pivoting movement of the contact portion about the pivot point GP. This is achieved according to the illustration in FIGS. 2 through a meandering, here in particular S-shaped, variable section VAB.

Starting from the example illustrated in FIG. 2A, in which the mating contact GK eccentrically meets the funnel-shaped section KTR, it is now necessary for the contact section KAB to be pivotable in order to achieve a reliable engagement in a direction RU (one image upwards) the counter contact GK can hit the contact point and a contact of the mating contact by both spring bars FEI and FE2 is made possible for a good current carrying capacity. By forming the variable portion VAB in an S-shape, when the contact portion VAB is pivoted in the direction RU, the S-shaped portion is expanded (the curvature of the bulbous portions of the "S" is reduced), so that a connection point VP of the first Stegs STl with the base web BAS due to the pivoting about the hinge point GP a movement to the right in the direction of the arrow LR and upward in the direction of the arrow LU (ie along the mounting direction RM and perpendicular thereto) learns.

Assuming that the pivoting of the contact portion KAB carried out around the hinge point GP is in the AO hezustand or unloaded state of the electrical plug element ESE offset in Figure 2B illustrated example, an axis corresponding to a Ru ^¬ by an angle VI counterclockwise or pivoted so that the plug element ESE after Pivoting in the direction of the arrow RU has a first displaced axis AU, which is said to be rotated by the angle VI of the unloaded axis AO. Referring now to FIG 2C, in which once again a case in which the contact point with the KS he shall purify ^¬ an engaging one eccentrically positioned mating contact GK. In this case, in an initial state analogous to FIG. 2A, the mating contact GK would impinge not on the upper, but on the lower spring web FEI (off-center). In order to allow now an engagement with the contact point, during assembly, ie the movement of the electrical

Plug element ESE in the mounting direction RM of the contact portion KAB along the arrow RD move perpendicular to the mounting direction to allow a position alignment and thus a secure engagement. For this purpose, the contact portion KAB is in turn pivoted about the pivot point GP, whereby the variable VAB is thereby compressed or compressed. More specifically, the connection point VP now moves downward in a direction of the arrow LD and leftward in a direction of the arrow LL toward the foot portion FAB. Thereby, the curvature of the belly-like portions of the S-shape is increased.

Assuming that the pivoting of the contact section KAB takes place about the articulation point GP, in the example shown in FIG. 2C the axis AO is displaced or pivoted by an angle V2 in the clockwise direction in accordance with the idle state or unloaded state of the electric plug element ESE that the plug element ESE, after pivoting in the direction of the arrow RD, has a first shifted axis AD which, as stated, is rotated by the angle V2 from the unloaded axis AO.

In this way, by the special design of the ver ^¬ mouldable portion VAB pivoting of the contact portion KAB be enabled around the pivot point GP of the first bridge. In particular, the provision of two webs ST1 and ST2 for connecting the fixing portion with the contact portion ge ^¬ ensures high current-carrying capacity of the electrical plug element and allows a positional compensation of Kon ^¬ clock section in misalignment.

Reference is now made to Figure 3, in which a sectional view of the front or free end of the support member TRE is shown to illustrate the inclusion of an electrical connector element ESE in the support member. The carrier element TRE has a respective recess for both the electrical plug element ESE and the electrical plug element ESE2. This recess AMM (shown in the example only for the electrical connector element ESE, but analogously apply to ESE2) has an opening OFN, through which a respective electrical connector element ESE is inserted into the recess. In the example of the plug element ESE, the opening is aligned upward in the image, so that the electrical connector ESE during assembly in the direction from top to bottom along the arrow RE is set such that the fixing portion FAS of the electrical connector element in the holding portion HAA of the support element intervenes. As already mentioned, the electrical connector is then pressed by means of the Christmas tree TST in the holding section HAA.

As can be seen in FIG. 3, the opening OFN is aligned such that the electrical plug element ESE (also ESE2) is to be inserted into the corresponding recess ANM perpendicular to the mounting direction. Associated with this, it is possible for the foot section FAB of the electrical plug element ESE to abut against an inner wall or against a stop section AAS of the recess ANM. This direct contact with the perpendicular to the mounting direction extending inner wall stabilizes the electrical connector element ESE when it is in the assembly of the Insert module ESM in the motor housing MGH meets the corresponding connector corresponding. In particular, in the case of an incorrect positioning of the plug connectors SV1 or SV2, the electrical plug element ESE experiences a support through the stop section AAS.

To further improve the stability, the recess ANM is aligned in the carrier element such that the electrical plug element ESE is aligned in the installed state in the mounting direction. In addition, the distance of the inner walls of the recess ANM, which run parallel to the image plane, in the region of the contact portion substantially equal to the width of the electrical connector element, so that a guide of the electrical connector element is given by the inner walls of the recess. As shown in particular for the recess of the second electrical connector element ESE2, a respective recess ANM of the carrier element further comprises an elongate slot ASZ which substantially corresponds to the slot SZ between the spring bars FEI and FE2 of the contact section. This slot ASZ allows a comb-like counter-contact ^¬ GK, as shown for example in Figure 2A, can properly engage with the contact point KS. For position alignment carrier element against a mating contact GK has a respective slot ASZ also the recess ANM advantageously at its free end a recess-side funnel portion TTR to lead the mating contact already from the side of the support member in the direction of the contact point. It should be mentioned that the corresponding receptacle for the second plug element ESE2 is designed such that its opening is also perpendicular to the mounting direction RM and in an opposite direction to the opening OFN. Reference is now made to Figure 4, in which a bottom view of the plug-in module according to the embodiment of the invention, as described above, can be seen. In this figure, the geometric relationships between plug and connector body will now be considered in more detail. As was already apparent from the preceding figures, the plug-in module ESM has a plug STK for insertion into a housing MGH of the motor unit along the mounting direction RM. In this case, the plug has the carrier element TRE with an axis ATR parallel to the mounting direction RM. In the carrier element, a recess ANM can be seen, into which via the opening OFN an electrical

Plug element used and can be pressed in the recess ANM, as shown in Figure 3. As can be seen in the center of Figure 4, the carrier element is TRE from on or off an edge portion of the second RAB of the surface FS2 Verbindungsab ^¬ VAS-section at a right angle. Furthermore, the connection piece AST of the connection body ASK protrudes at an angle W from the connection section VAS. Due to this arrangement of the fitting AST at an angle to the connecting portion VAS it follows that the through-holes DGAbzw. are not aligned parallel to the mounting direction RM through these passing through axes ADG of the through holes. Rather, the axes of the respective passage recesses also have the predetermined angle W to the mounting direction RM, which is smaller than 180 °.

As can be seen in Figure 4 also, the support member TRE is such at the edge portion RAB the second surface FS2 be ^¬ arranged that the outlet openings of the through holes on the second surface FS2 are facing the carrier element TRE or the inside thereof. In other words, the Trä ^¬ gerelement TRE is mounted in such a way on the second side surface such that an imaginary extension of each through hole crosses the axis of the support member ATR TRE. As in the figure 4, the axes ADG of the passage recesses intersect the axis ATR of the support element also at the angle W.

FIG. 5 now shows a view of the plug-in module ESM from the side, in particular from a viewing direction on the outside of the carrier element TRE, ie the second surface FS2 or the side of the carrier element opposite the outlet openings of the passage openings. As can be seen in Figure 5, includes the support member between the portion for receiving the plug elements (the exposed portion of the Trägerele ^¬ ments) and connected to the connecting portion VAS portion a recess OFF. As will be explained in the following figures, this recess serves in particular for inserting or mounting the contact pins ESK1, ESK2 and further contact pins in the connection body ASK.

To explain the assembly of the electrical contact pins in the connector body ASK reference is now made to Figure 6, in turn, a view of the plug-in module ESM is shown from below. Reference is made at the same time to FIG. 7, which shows a section parallel to the image plane of the plug-in module shown in FIG. 6 in order to clarify the geometric relationships within the connection body ASK. After the plug and the terminal body have been produced as an integral component with an injection molding process and, accordingly, the contact pins were preferably produced as stamped parts from a metal sheet, these components must be brought together. In the injection molding process, a plurality of through holes DGA have been formed in the terminal body ASK, which extend from a first side surface FS1 to an opposite second side surface FS2 of the terminal body for receiving therein electrical contact pins. When assembling the plug-in module ESM now the electrical contact pins ESK1 and ESK2 (and possibly more) merged such that the second end portions EA12 and EA22 of the electrical contact pins are inserted into the respective inlet openings of the respective passage recesses on the first side surface FS1. Then, the per ^¬ weiligen contact pins along the axis of the passage ADG ^¬ recesses DGA or along the insertion directions RE1 and RE2 are moved or pushed (in the picture from left to right). More specifically, the electrical contact pins ESK1, ESK2 are pressed into the connector body ASK, such that a respective fir tree-like structure KST1 and KST2 the electrical contact pins into a respective through-hole into ^¬ presses is such that this portion of the passage ^¬ recess in its dimensions expands and begins to flow. In this way, the electrical contact pins are held by the material of the connection body, which has flowed between the extensions of the fir-tree-like structure. Furthermore, a projection VI or V2 is formed on a respective electrical contact pin ESK1 and ESK2, which prevents further movement of the contact pin in a direction RE1 or RE2 after coming into contact with a corresponding shoulder S1 or S2 of the connection body. In this way, an accurate positioning of the electrical contact pins can be ensured.

As can be seen on the right side of Figure 6 or 7, the angled arrangement of the fitting AST relative to the connecting portion VAS, the at least the second end portion EA12 of the first electrical contact pin ESK1 due to its elongated structure (for passing through the through holes during assembly is necessary) would encounter the support element TRE. However, as has already been mentioned with reference to FIG. 5, the carrier element has a recess AUS, which is dimensioned in such a way that in that electrical contact pins, the ends of which protrude from the second side surface FS2, pass through the carrier element

can pass through and do not trigger on this. By providing the recess AUS in the carrier element and a corresponding measurement, it is also possible that a tool for a subsequent processing of the respective second end portion of an electrical contact element can penetrate from the outside through the carrier element to the second end portions in order to process them , In a subsequent processing step, the second sections EA12 and EA22 (and possibly further end sections) are then processed in such a way that they are bent downwards perpendicular to their outlet direction, as can be seen in FIG. Thus, it is then possible that from the bottom (see FIG. 5 and Figure 8) zoom out to the plug-in module circuit board on the one hand with the second Endab ^¬ cut EA1, EA2, and further the electric contact pins can be connected, as well as to the terminals of LPA and LPA2 of electric plug elements ESE or ESE2. If the printed circuit board has now been attached to the plug STK and connected to corresponding electrical connections of the contact pins or the electrical plug elements, a functional plug-in module ESM is produced, as shown in FIG. Now in the process carries the plug has STK both a support member and an associated printed circuit board LP, the electrical contact pins and the elekt ^¬ step plug elements are connected to the egg ^¬ nerseits, and further electronic components EBS, for example, a relay RL, etc. ,

Such a functional plug-in module ESM can now, as can be seen in FIG. 9, be introduced into a housing MGH, a motor unit ME along a mounting direction RM. In this case, provided on the support element TRE electrical Plug elements ESE with the corresponding mating contacts or connectors SVl or SV2 of the motor unit ME engage to supply electrical power or electrical energy via the plug-in module ESM of the motor unit ME. To facilitate insertion of the plug-in module into the housing MGH or for improved alignment of the carrier element and the electrical plug elements held therein, the carrier element has a guide section FUA (see also FIGS. In order to further allow a tolerance compensation between the electrical connector elements and the corresponding mating contacts SVL and SV2, the support element or the electrical plug contacts the measures described in the preceding figures, so that a loss of function of the plug-in module ESM in non-aligned supply of electrical

Plug elements or motor contacts to their mating contacts in the motor housing by damage to the electrical

Plug elements is avoided.
