Abstract
Description
Technical Field
[0001] The present invention relates to a connecting element according to the preamble of the independent claim and an electronic device including the connecting element. Background Technology
[0002] Due to legal requirements and for reliable operation, many electronic devices must be grounded via a grounding connection. If the electronic device has an electrically insulating plastic housing, the grounding connection typically passes through the housing. A simple implementation involves a grounding connection point fixed to the circuit carrier of the electronic device having a conductive structure around a recess in the circuit carrier. A screw passes through this recess and makes electrical contact with a pre-installed grounding line in the plastic housing. In this case, the screw, for example, clamps the circuit carrier onto a raised portion of the plastic housing, which also includes the grounding line in electrical contact. The screw head can then abut against the grounding connection point of the circuit carrier. Thus, the screw functions as both an electrical and mechanical connection element. However, a problem arises during operation: due to the different expansion characteristics of the corresponding components of the electronic device, relative movement occurs during temperature changes, threatening the reliable operation of the grounding connection. In particular, this can lead to thermomechanical stress states, which may cause material failure, material fatigue, and ultimately, material fracture within the required conductive structure of the grounding connection. Furthermore, in some designs of electronic devices, tolerance chains can accumulate unfavorably, making it impossible to reliably form electrically defect-free grounding connections during assembly. Tolerance issues, combined with the varying expansion characteristics of components, further exacerbate unreliability. Summary of the Invention
[0003] The purpose of this invention is to reliably realize electrical and mechanical connections in electronic devices, particularly the electrical and mechanical connections of the grounding connection of the electronic device.
[0004] This objective is achieved by a connecting element having the features of the independent claims and an electronic device including at least one such connecting element.
[0005] Therefore, the present invention is based on a connecting element for indirectly connecting two connecting components to each other, the connecting element having a first connecting junction for connecting with a first connecting component and a second connecting junction for connecting with a second connecting component. Thus, in the connected state, the connecting element is designed to bridge the force flow between the two connecting components between the first connecting junction and the second connecting junction. Here, the first connecting junction is formed in a first region, and the second connecting junction is formed in a second region spaced apart from the first region. The first and second regions are connected to each other via a flexible third region. Thus, the force flow acting between the first and second regions is flexibly coupled through the third region. The connecting element is preferably an integral design. Furthermore, the connecting element is designed, particularly as at least part of a grounding connection device, to form a grounding connection line serving as the circuit carrier of the first connecting component. Advantageously, through the flexible third region, the first region, or the first connecting junction, and the second region, or the second connecting junction, are coupled to each other, allowing their respective positions relative to each other to change. This elastic movement capability effectively reduces the stress typically generated in the aforementioned areas or connection joints, caused by the forces resulting from the different expansion characteristics of the two connecting components. Furthermore, assembly tolerances can be conveniently compensated for. Therefore, the geometry of the third region advantageously compensates for existing positional and locating tolerances of the two connecting components arranged relative to each other and to be connected by the connecting element. The flexibility of the third region thus ensures that the first and second regions adapt to the positions of the first and second connecting components without mechanically loading the first and second connection joints due to stress states that would otherwise apply. Therefore, as at least part of the grounding connection device, the connecting element reliably forms a grounding line even under conditions of temperature changes during operation or stringent tolerances of the connecting components during assembly. Of course, the connecting element is conductive at least between the first and second connection joints, and preferably conductive overall. For this purpose, the connecting element is preferably formed of a metallic material, such as copper, aluminum, silver, or alloys thereof. This metallic material can also be applied as a layer on or within the substrate of the connecting element, and the substrate can also be made of an electrically insulating material.
[0006] The contact device according to the invention can be advantageously improved and refined by the measures listed in the dependent claims.
[0007] In an advantageous embodiment of the connecting element, the first and / or second regions are flat, at least in the region of the first or second connection junction, preferably the entire first and / or second regions are flat. This achieves simple assembly conditions for forming particularly low impedance contact, which is especially important for the function of forming a grounding line via the connecting element.
[0008] In another advantageous embodiment of the connecting element, the first connection joint is designed as a brazed, soldered, or adhesive tab. This allows the connecting element designed in this way to be used as an SMD (Surface Mount Device) device, which provides a cost-effective construction and connection technology in the electronics manufacturing industry. In this case, the first connection joint is particularly designed to connect the connecting element to a complementary connection joint on the surface of the circuit carrier, which serves as the first connection participant. Thus, the elastic flexibility of the third region advantageously and effectively protects the construction and connection technology used from mechanical stress conditions.
[0009] Preferably, as an additional option to the aforementioned embodiments of the connecting element, the second connecting joint is also designed as a brazed connecting piece, a welded connecting piece, or an adhesive connecting piece, and has the same advantages already mentioned. An equivalent alternative is that the second connecting joint takes the form of a screw-on tab, which includes a through hole for the connector. This connector is preferably a fastener with a threaded portion, such as a fastening screw or bolt sleeve. In this case, the second connecting joint is particularly designed to connect the connecting element to a complementary connecting joint located in a housing element that serves as a second connecting component. The embodiment with the screw-on tab also facilitates disassembly, for example, during repair or maintenance work on a higher-level device, particularly an electronic device, in which the connecting element is arranged or used, particularly as part of a included grounding connection device.
[0010] In one embodiment, the first region forms at least one meandering section with the elastic third region and / or the second region with the elastic third region, thereby achieving a particularly simple, geometrically induced flexibility within the connecting element. The number of meandering sections, their respective orientations, and their respective cross-sections are designed according to the specific application to achieve the required flexibility. The meandering sections can cover a wide range of achievable flexibility. The correspondingly designed flexibility also determines the possible force transmission between the first and second regions. Direction-dependent flexibility can be achieved by correspondingly arranging at least two or more meandering sections of different designs. A very simple connecting element is obtained by arranging at least one meandering section in the same plane as the first and / or second regions. It is particularly advantageous if the first, second, and third regions are arranged in the same plane. The connecting element can then preferably be formed from a plate-like substrate in the base plane of the plate, for example, by a cutting process. However, in principle, at least one meandering section can also be arranged in a plane parallel to the first and / or second regions. For example, this may be necessary if the connecting components are connected in the same plane and / or staggered from each other at a certain layer angle. The different planes within the connecting elements can be formed, for example, by a stamping process. This also applies, for example, to an alternative implementation where at least one meandering portion is arranged in a plane perpendicular to the first and / or second region. This implementation is similar to, for example, the connection pins of an electrical device soldered via SMD.
[0011] In a preferred embodiment of the connecting element, during the connected state and when a force is introduced to the first and / or second connecting joints, the positions of the first and / or second regions move along the direction of translational and / or rotational movement. This continues until a force balance is achieved between the first and second regions, wherein an elastic third region provides a reaction force to the introduced force. Thus, by means of the elastic and flexible third region, the coupling of the first and second regions allows relative movement caused by temperature within the connecting region without adversely increasing the force acting on the first and / or second connecting joints. By designing for flexibility, the maximum force can be determined very flexibly. Furthermore, this allows for a reliable connection even when assembly tolerances are large and the connection positions vary significantly.
[0012] In a particularly advantageous embodiment of the connecting element, the third region transitions to the first region via a first coupling end and to the second region via a second coupling end. Here, the third region locally has at least one or more elastically flexible compensation structures designed to compensate for changes in the distance between the first and second coupling ends by elongation or shortening of the third region's elastic force when the relative positions of the first and second regions change, for example, due to the force introduced by the connecting element in a connected state. Therefore, the elastic flexibility in the compensation structure region is additionally superimposed on the already mentioned elastic flexibility of the third region itself. However, the elastic flexibility of the compensation structure here allows for adjustment of the length of the third region when the relative positions of the first and second regions change. This length adjustment ensures that no internal stress state is established in the connecting element, which, without such length adjustment, could cause the connecting element as a whole to be stressed, thus exerting adverse forces on the first and second connection junctions.
[0013] In one embodiment of the connecting element, further advantages are achieved, in which at least two or more first connecting joints are formed, each arranged about a connecting axis of a second connecting joint by a rotational angle. In this case, particularly in the rotational arrangement of the first connecting joints, starting from one first connecting joint and proceeding sequentially to the last, all consecutively adjacent first connecting joints about the aforementioned connecting axis have the same rotational angle. The resulting rotational arrangement including the first connecting joints is also preferably rotationally symmetric, point-symmetric, axisymmetric, and / or partially symmetric. By strategically arranging the first connecting joints in this manner, a very specific influence can be applied to locally desired, direction-dependent flexibility, with the aim of introducing forces specifically for the application in the first and / or second regions. This also allows for better distribution of force transmission throughout the connecting element, thereby reducing the load borne by the connecting element itself.
[0014] In a particularly preferred embodiment, the connecting element is a sheet metal, particularly a stamped or laser-cut part. This allows for the very low-cost and high-volume manufacturing of the connecting elements according to the above embodiments. This is especially important when the connecting elements are used in mass-produced electronic devices. Furthermore, the connecting elements are particularly made of spring steel, thus maintaining their elastic flexibility throughout their service life even under drastic load variations.
[0015] The present invention also proposes an electronic device comprising a connection element according to at least one of the foregoing embodiments. Here, a first connection junction is connected to a complementary connection junction on the surface of a circuit carrier of the electronic device. This complementary connection junction is, for example, a contact pad, particularly made of a copper- or silver-containing material. The contact pad preferably makes electrical contact with the conductive structure of the circuit carrier. More preferably, the complementary connection junction is designed as a ground connection point of the circuit carrier. Furthermore, a second connection junction is connected to a complementary connection junction in a housing element of the electronic device. This housing element comprises multiple housing elements, for example, two housing elements, which house the circuit carrier within a formed cavity in a connected or closed state. The circuit carrier is preferably mechanically fixedly connected to one of the housing elements. Furthermore, the circuit carrier is electrically connected to one of the housing elements by means of a connection element that is part of a grounding device of the electronic device.
[0016] In an advantageous embodiment of the electronic device, the housing element is formed of an electrically insulating plastic material. Furthermore, a fastening sleeve for securing the electronic device to its operating environment is embedded in one of the housing elements. This fastening is, for example, performed on a carrier plate. The operating environment can also be, for example, a vehicle body, particularly a motor vehicle body. In this case, the electronic device is designed, for example, as a controller, computer device, or sensor module. Here, one end of the fastening sleeve extends to the exterior of the housing comprising the housing element and at least one other housing element, and the other end extends into the interior of the housing. The fastening sleeve is conductive, and a grounding connection is also provided between the circuit carrier and the operating environment by designing the inwardly extending end of the fastening sleeve into the housing as a connection junction complementary to a second connection junction of the connecting element. In this way, the grounding connection of the electronic device can be designed with very low impedance. Furthermore, due to the aforementioned flexibility of the connecting element within the grounding connection device, the grounding connection can be reliably maintained throughout the entire service life of the electronic device.
[0017] In an advantageous embodiment of the electronic device, the circuit carrier, particularly in its edge region, has at least one notch, wherein the at least one notch is partially or substantially completely bridged by a connecting element. Furthermore, a first region of the connecting element is then arranged adjacent to the edge region of the notch, and second and third regions are arranged within the region of the notch. Because the grounding connection is implemented within the region of the circuit carrier, a compact structure is maintained even if the grounding line design is reliable in operation.
[0018] In an improved embodiment, the connecting element is held clamped between the fastening sleeve and the clamping sleeve. Here, the clamping sleeve is arranged on the opposite side of the connecting element. The clamping sleeve has a shaft region that passes through a recess in another housing element until a radially projecting flange of the clamping sleeve, adjacent to the shaft region, abuts against the other housing element from the outside in the region of the recess. A continuous channel is formed in the clamping sleeve, which protrudes as openings at both ends in the flange or shaft region. Furthermore, the fastening sleeve has at least one screw thread, particularly an internal thread, which effectively connects with the corresponding screw thread of a connector, particularly a screw with external threads, passing through the channel of the clamping sleeve. In this effective connection, a clamping force is thus formed acting on the connecting element between the fastening sleeve and the clamping sleeve. The direction of this clamping force is particularly perpendicular to the second region.

[0021] Figure 1 A portion of an electronic device with cutouts is shown in a perspective view of a grounding connection device including connecting elements;
[0022] Figure 2 A top view is shown. Figure 1 The connecting elements in the diagram also show the edge region around the notch in the circuit carrier of the electronic device;
[0023] Figures 3a to 3e Different embodiments of the connecting element are shown in perspective. Detailed Implementation
[0024] In the accompanying drawings, the same reference numerals are used to denote components with the same function.
[0025] Figure 1 A portion of the electronic device 100 is shown in a perspective view. The electronic device includes a housing 10 formed by a plurality of housing elements. The following embodiment is described using two housing elements 11 and 12, each made of electrically insulating plastic material, but this is merely an example.
[0026] In the assembled state of the housing 10, a cavity 50 is formed, which accommodates at least one circuit carrier 20. An electronic and / or electrical circuit 21 is formed on the circuit carrier 20, which provides defined electrical functions during the operation of the electronic device 100. Figure 1A notch in the housing 10 is also shown, revealing the circuit carrier 20 and other components of the electronic device 100. Specifically, components of a grounding connection device 30 are shown, through which a grounding connection line 30' of the circuit carrier 20 is formed. The grounding connection device 30 includes a connecting element 35 that mechanically and indirectly connects the circuit carrier 20 as a first connection participant to at least one of the housing elements 11, 12 as a second connection participant. Figure 2 It shows Figure 1 The connecting element 35 is located in the region of the ground connection point 25 of the circuit carrier 20 or the electrical and / or electronic circuit 21. In this embodiment, the ground connection point 25 is arranged in the region of the recess 20. The recess 20.1 is arranged at the edge region of the circuit carrier 20 such that the recess 20.1 is open toward the edge edge of the circuit carrier 20. In other embodiments, the recess 20.1 may also be closed. The connecting element 35 is arranged above the recess 20.1 from one side of the circuit carrier 20 such that the connecting element 35 is at least partially, preferably as Figure 2The notch is substantially completely covered or bridging as shown. The connecting element 35 has multiple functional regions. These functional regions include a first region 35.1 disposed in the edge region of the notch 20.1, and at least one second region 35.2 disposed within the notch 20.1, spaced apart from the first region 35.1. The first region 35.1 and the second region 35.2 are interconnected by a flexible third region 35.3. In the current embodiment, three first regions 35.1 are constructed, each connected to the second region 35.2 via a third region 35.3. In the top view, all three first regions 35.1 are arranged here on one side of the circuit carrier 20 and are rotatably arranged about the fastening axis S of the second region 35.2 by a rotation angle α. When the rotation angle is 90°, the three first regions 35.1 substantially cover the region formed along the edge of the notch 20.1. The first region 35.1 has a first connection junction 35.1a on the side facing the circuit carrier 20, through which the connecting element 35 is mechanically and electrically connected to the side surface of the circuit carrier 20. The electrical connection is established via a ground connection point 25 of the circuit carrier 20, which is designed as a connection junction complementary to the first connection junction 35.1a. The ground connection point 25 is connected, for example, to the wiring structure of an electrical and / or electronic circuit 21. Specifically, the first connection junction 35.1a is designed as a brazed tab, solder tab, or adhesive tab. The first region 35.1 and preferably the second region 35.2 are flat or entirely flat, at least in the regions of the first connection junction 35.1a or the second connection junction 35.2a, so that the connecting element 35 can ultimately be connected, preferably by means of brazing contacts, during the assembly of the circuit carrier 20 as an SMD device. The second region 35.2 has a second connection joint 35.2a on the side facing the housing elements 11 and 12 to be connected. The second connection joint 35.2a can also be a brazed connector, a welded connector, or an adhesive connector. As another feasible embodiment, in... Figure 1 , Figure 2 , Figure 3a , Figure 3b , Figure 3c and Figure 3e The second connecting portion 35.2a is shown as a screw tab. This screw tab 35.2a includes a through hole 36.
[0027] Figure 1The fastening of the circuit carrier 20 to the housing 10 is best illustrated. In the first housing element 11, a fastening sleeve 15 is embedded in the plastic material of the first housing element 11, aligned with the fastening axis S of the second region 35.2 of the connecting element 35. The fastening sleeve 15 contains a fastener accessible from the side of the connecting element 35. The fastening sleeve 15 has, for example, internal threads. The shaft region 16.1 of the clamping sleeve 16 passes through a corresponding recess 12.1 in the second housing element 12, which is also aligned with the fastening axis S of the second region 35.2. Here, the flange 16.2 of the clamping sleeve 16, adjacent to the shaft region 16.1, is located from the outside in the edge region of the recess 12.1 on the second housing element. Furthermore, a fastener 37, such as a fastening screw, passes through the clamping sleeve 16 and further through the recess 36 of the screw tab 35.2 to the fastening sleeve 15. By effectively connecting the fastener 37 to the fastening sleeve 15, a clamping connection 40 is formed between the fastening head 37.1 of the fastener 37 and the fastening sleeve 15. In this case, the clamping sleeve 16 physically abuts against the second region 35.2 from the first side and the fastening sleeve 15 from the opposite second side. In this connected state of the connecting element 35, the housing 10 is mechanically and electrically connected to the circuit carrier 20, wherein the connecting element 35 here bridges the force flow between the two connecting components between the first connecting junction 35.1a and the second connecting junction 35.2a, or in other words, couples the effective force flow between the first region 35.1 and the second region 35.2 through the third region 35.3. Due to the elastic flexibility of the third region 35.3, changes in the respective positions of the first region 35.1 and the second region 35.2 can be compensated. The corresponding positional changes here may include movement along the direction of translational movement and / or rotational movement. Positional changes may occur during assembly due to assembly tolerances of the parts to be connected, or during operation due to different expansion characteristics, particularly of the parts being connected. The clamping connection 40 simultaneously forms the aforementioned grounding connection device 24. For this purpose, the components involved are made of a conductive material. The connecting element 35 is preferably integrally formed from a sheet metal, particularly a stamped sheet or a laser-cut piece. To provide the elastic flexibility of the third region 35.3, the connecting element 35 is ideally formed from an elastic sheet metal. To ensure the grounding connection, the electronic device 100 is electrically connected to its operating environment G via the grounding connection device 24. The operating environment G is, for example, a foundation structure, such as the body structure or frame structure of a motor vehicle. The electronic device 100 is fastened to the operating environment G, for example, by means of threads, using another connection junction of the fastening sleeve 15 accessible from the outside of the housing 10. Thus, an electrical path to the operating environment G can be formed via the grounding connection device 24.
[0028] Figure 3aThe aforementioned connecting element 35 is shown again separately in a perspective view. It can be seen that the first region 35.1 and the elastic third region 35.3, and / or the second region 35.2 and the elastic third region 35.3, form at least one meandering portion 35.123. The first region 35.1 and the second region 35.2 are firmly connected to the corresponding connecting elements 10.1, 10.2, 20, while the third region can move within the region of the notch 20.1 of the circuit carrier 20 to adapt to the corresponding positions of the connecting elements 10.1, 10.2, 20. This mobility primarily stems from the ability of the third region 35.3 to pivot around the corresponding pivot axis A within the regions of the first coupling end 35.3a and / or the second coupling end 35.3b, through which the third region 35.3 elastically and flexibly transitions to either the first region 35.1 or the second region 35.2, respectively.
[0029] In principle, the third region 35.3 may include multiple identical or different meandering sections 35.123. Figure 3b and Figure 3c Other embodiments of the connecting element 35 are shown. Figure 3a Three first regions 35.1 are shown, arranged 90° around the fastening axis S; while according to Figure 3b The embodiment has two first regions 35.1 arranged opposite to each other with respect to the through hole 36, and according to Figure 3c The embodiment has four first regions 35.1 arranged by rotating 90° around the fastening axis S. The number of first regions 35.1 and the corresponding rotation angle α around the fastening axis S in the rotational arrangement can be adjusted accordingly according to the application, especially to give the correspondingly formed third region 35.3 orientation-dependent flexibility. The rotational arrangement of the first regions 35.1 is preferably rotationally symmetric, point-symmetric, axisymmetric, and / or partially symmetric.
[0030] Although the embodiments to date show that the first region 35.1, the second region 35.2, and the third region 35.3 are located in the same plane, it is also conceivable that the first region 35.1 and the second region 35.2 are arranged in a manner that is parallel to each other and / or tilted at an angle to each other. The third region 35.3 extends between these different planes.
[0031] At least one additional flexible and resilient compensating structure 35.321 can be formed within the third region 35.3. Figure 3dThe compensation structure 35.321 is shown in enlarged view. This compensation structure is, for example, arranged in the region of the meandering portion 35.123. The compensation structure 35.321 is designed to cause a change in the distance between the first coupling end 35.3a and the second coupling end 35.3b by the elongation or shortening of the third region 35.3 through the elastic action of the third region 35.3 when the relative positions of the first region 35.1 and the second region 35.2 change—for example, when expansion occurs due to temperature changes. The compensation structure 35.321 has, for example, at least one meandering portion. The meandering portion of the compensation structure 35.321 extends in a different plane than the meandering portion 35.123 formed between the first region 35.1 and / or the second region 35.2 and the third region 35.3, particularly in a plane perpendicular to it.
[0032] Figure 3e A final embodiment of the connecting element 35 is shown. Unlike the previously shown embodiments, the meandering portion 35.123 formed between the first region 35.1 and / or the second region 35.2 and the third region 35.3 extends in a plane perpendicular to the first region 35.1 and the second region 35.2. A plurality of such meandering portions 35.123 are arranged around the second region 35.2, making the connecting element 35 resemble an electrical device with connecting pins.
