Description

Technical Field

[0001] The invention relates to an electromechanical assembly for a control device, characterized in that a plug module, in particular in the form of a high-frequency interface, is particularly advantageously arranged in the area of ​​a plug terminal strip of the assembly. The invention also relates to a control device having an electromechanical assembly designed according to the invention. Background Art

[0002] DE 102 56 374 B3 discloses arranging a plug module in the area of ​​a plug terminal strip having a two-part module housing. The two components of the module housing are introduced into a receiving opening of the plug terminal strip from opposite sides and locked together to secure the plug module to the plug terminal strip.

[0003] Furthermore, it is known from DE 10 2017 113 415 A1 to arrange a press-in socket and a supporting sleeve in an adapter housing of a plug module, into which the press-in socket and the supporting sleeve can be pressed.

[0004] It is also known from DE 10 2009 023 292 B4 to form an electrical connector with a contact carrier having a contact carrier composed of two contact carrier units, which can be connected to one another via guide surfaces and positioned relative to one another. Summary of the Invention

[0005] The electromechanical assembly according to the invention for a control unit having the features of claim 1 has the advantage that it is arranged particularly securely or securely in a fixed manner in the receiving opening of the plug terminal strip, a relatively simple assembly process is achieved for forming the assembly, and the assembly comprises a small number of components. Furthermore, not only is a highly precise positioning of the plug module relative to the receiving opening in the plug terminal strip possible, but also a highly precise positioning of the terminal pins of the plug module relative to the printed circuit board arranged in the control unit is achieved, thereby ensuring simple installation or connection between the terminal pins of the plug module and the printed circuit board.

[0006] Against the background of the above explanations, an electromechanical component for a control device having the features of claim 1 is therefore provided, the component having a plug terminal strip made of plastic and a receiving opening formed in the plug terminal strip for accommodating a plug module, wherein the plug module has a module housing that can be introduced into the receiving opening of the plug terminal strip in the direction of the longitudinal axis of the module housing up to an end position, wherein the plug module has at least one terminal pin that is designed to contact a printed circuit board of the control device, wherein the module housing has a guide section with at least two side faces lying opposite each other with respect to the longitudinal axis, which cooperate in a form-fitting manner with mating surfaces formed in the receiving opening of the plug terminal strip, and wherein the module housing has locking sections in the region of the guide section on opposite sides outside the side faces, the locking sections having projections and / or recesses that cooperate with recesses and / or projections formed in the receiving opening outside the mating surfaces to form a force-fit connection in the receiving opening of the plug terminal strip in the end position of the module housing.

[0007] Advantageous developments of the electromechanical assembly according to the invention for a control device are listed in the dependent claims.

[0008] In a preferred structural design scheme of a locking section for minimizing the cross-section of the guide area, it is proposed that the locking section is constructed in the area of ​​a corner area of ​​the module housing that is arranged perpendicularly to the longitudinal axis and perpendicular to the side plane and extends in the direction of the longitudinal axis, and the cross-section of the module housing in the area of ​​the guide section is rectangular except for the corner area.

[0009] A particularly strong and reliable locking or a particularly high pull-out force is achieved if four locking sections are formed at the four corner regions of the guide section.

[0010] It is also preferred that the plug terminal strip has at least one extension on the side facing away from the plug collar, extending from the receiving opening and forming an axial stop, for securing the module housing in the receiving opening. This reliably limits the insertion path of the module housing when mechanically inserting or pressing the module housing into the receiving opening, and thus also precisely positions the terminal pins in the longitudinal direction relative to the circuit board.

[0011] If the module housing and / or the receiving opening are at least partially conical when viewed in the direction of the longitudinal axis, the process of pressing the module housing into the receiving opening can be optimized.

[0012] The module housing preferably has an opening extending in the direction of the longitudinal axis for accommodating the socket insert, wherein at least one terminal pin is accommodated in the socket insert with a force-fitting fit, and wherein the socket insert is pressed into the opening. Furthermore, the socket insert and / or the module housing can have electromagnetic shielding in a known manner, in particular when the plug module is designed as an Ethernet terminal.

[0013] In order to optimize the module housing with regard to easy introduction into the receiving opening and achieving an end position relative to the plug terminal strip, it is proposed that the module housing has two additional sections on both sides of the guide section when viewed in the direction of the longitudinal axis, wherein the additional section facing the plug terminal strip has a smaller cross-section than the guide section and the other additional section has a larger cross-section than the guide section.

[0014] The present invention further comprises a control device, in particular for motor vehicle use, having an electromechanical component designed according to the invention as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Further advantages, features and details of the invention will be found in the following description of preferred embodiments of the invention and with reference to the drawings.

[0019] Figure 4 shows a cross section of a detail of a plug terminal strip with a plug module inserted into a receiving opening,

[0020] Figure 5 Shown is a longitudinal section through the region of a receiving opening in a plug terminal strip in which a plug module is arranged. DETAILED DESCRIPTION

[0021] In the figures, identical elements or elements having the same function are provided with the same reference numerals.

[0022] exist Figure 1 , a control device 100 is shown, which can be used in particular but not exclusively for motor vehicle applications. For example, when used in a partially autonomous or autonomous vehicle, the control device 100 is used to detect sensor data and process it to control drive elements or similar components of the motor vehicle.

[0023] Control unit 100 has a housing 102, which is typically constructed in at least two parts and is made of plastic and / or metal, for example, from uncut and machined sheet metal parts or from die-cast aluminum components. Connector terminal strip 12 is arranged at the end of housing 102 together with housing 102 as an integral part of mechatronic assembly 10. Control unit 100 is electrically connected via mechatronic assembly 10, in particular to a wiring harness of a motor vehicle (not shown).

[0024] Furthermore, at least one printed circuit board 104 (shown only partially) or a similarly designed circuit carrier, which has electronic components or electronic circuits in a known manner, is arranged in the housing 102. The printed circuit board 104 is electrically contacted with the electromechanical component 10 by connecting a plurality of terminal pins 14 arranged in the region of the plug terminal strip 12 to the printed circuit board 104, for example, by means of a soldered or press-fit connection.

[0025] The plug terminal strip 12 is designed as an injection-molded part made of plastic and includes, for example, two circumferential plug collars 16, via which a (not shown) plug (on the wiring harness side) can be connected to the control unit 100. Terminal pins 14 are also arranged in a known manner within the cross section of the plug collar 16 to contact the wiring harness-side plug. Furthermore, a plug module 20 is also arranged within the cross section of the plug collar 16 and connected to the plug terminal strip 12. The plug module 20 serves for data transmission and is designed as a high-frequency interface in the form of an Ethernet terminal 21.

[0026] To accommodate the plug module 20, as best described in accordance with Figure 2 and Figure 4 As can be seen, the plug terminal strip 12 has a receiving opening 22. The plug module 20 comprises a module housing 24 made of plastic and having an opening 25, wherein a socket insert 26 is inserted or pressed into the opening 25 and surrounds the two terminal pins 14 with a force fit. The terminal pins are usually bent at a right angle in this area of ​​the interior of the housing 102 and are connected to the printed circuit board 104.

[0027] Figure 3Module housing 24, shown in detail in FIG, has a longitudinal axis 28 along which module housing 24 or plug module 20 can be introduced, in particular pressed, into receiving opening 22 of plug terminal strip 12 until it reaches an end position. Furthermore, module housing 24 has a guide section 30 approximately in the center region, as viewed in the direction of longitudinal axis 28, with two additional sections 32, 34 being arranged on opposite sides of guide section 30 in the direction of longitudinal axis 28. One additional section 32 is arranged oriented toward the interior of housing 102 and has a larger cross-section or a larger cross-sectional area than guide section 30, while the other additional section 34 is arranged in a region within plug collar 16, that is, on the side facing away from the interior of housing 102, and has a smaller cross-section or a smaller cross-sectional area than guide section 30 and receiving opening 22, so that module housing 24 can be pushed in by introducing the other additional section 34 into receiving opening 22.

[0028] The guide section 30 is designed to be approximately rectangular or square in the direction of its cross section extending perpendicularly to the longitudinal axis 28 and has four side faces 36 to 39 which cooperate in a form-fitting manner with a subsection having mating surfaces 41 to 44 formed in the receiving opening 22 ( Figure 4 In the four corner regions 46 of the cross section of the guide section 30, a cutout 48 of rectangular cross section is arranged, extending in the direction of the longitudinal axis 28. The cutout 48 has a side wall section 50 extending parallel to the side faces 36 and 38, which is at least partially designed as a locking section 52 ( Figure 3 and Figure 5 ).

[0029] Especially from Figure 3 and Figure 5 As can be seen from the overview of FIG, the locking section 52 comprises a plurality of projections 54 and / or recesses 56 arranged one behind the other as viewed in the direction of the longitudinal axis 28. The projections 54 and / or recesses 56 cooperate with opposing recesses 58 and / or projections 60 formed in the receiving opening 22 when the module housing 24 is installed. Figure 5 ) to form a force-fit connection. In addition, according to Figure 5 It can be seen that the width B of the side surfaces 36 to 39 of the module housing 24 is greater than the width b of the seating surfaces 41 to 44 in the region of the receiving opening 22 .

[0030] In addition, it should be mentioned that the projections 54 and / or depressions 56 on the module housing 24 or the depressions 58 and / or projections 60 in the receiving opening 22 can also be designed in the form of barbs or similar geometric shapes. Furthermore, the plastic materials of the module housing 24 and the plug terminal strip 12 can be different, in particular having different hardnesses, so that, for example, the module housing 24 deforms less or not at all when forming a force-locking connection with the plug terminal strip 12. Furthermore, it can be provided that, viewed in the direction of the longitudinal axis 28, the receiving opening 22 and / or the module housing 24 are conically shaped, at least in the region of the locking section 52, so that the cross-section of the aforementioned elements tapers toward the plug collar 16. This can influence the required press-fit force for the module housing 24 into the receiving opening 22, in particular so that (the full) press-fit force only needs to be applied in the receiving opening 22 immediately before the axial end position of the module housing 24 is reached. Furthermore, such a taper can simplify removal of the plug terminal strip 12 or the module housing from the injection molding tool.

[0031] In addition, according to Figure 2 and Figure 5 1. It can also be seen that in the region of the receiving opening 22, on the side facing away from the plug collar 16, four extensions 62 protrude from the receiving opening 22. When the module housing 24 is pressed into the receiving opening 22, the extensions 62 formed in the extension of the recess 58 and the projection 60 of the receiving opening 22 form axial stops for the (axial) end position of the module housing 24 in the plug terminal strip 12 in the following way: the end side 64 of the section 32, which extends perpendicularly to the longitudinal axis 28, rests against the extensions 62. Figure 5 ).

[0032] To install the plug module 20 or the module housing 24, the module housing 24 is pushed or pressed into the receiving opening 22 of the plug terminal strip 12 in the direction of the longitudinal axis 28 until the module housing 24 is inserted into the receiving opening 22 of the plug terminal strip 12. Figure 5 Here, the projection 54 and / or the recess 56 of the locking section 52 abuts against the recess 58 and / or the projection 60 in the receiving opening 22 .

[0033] The electromechanical assembly 10 described above may be modified or changed in various ways and methods without departing from the spirit of the present invention.
