Description

ELECTRICAL CONNECTION DEVICE

The present invention relates to an electrical connection device for contacting an electronic component module with an electrical line, in particular with a flexible flat line with a plurality of strip conductors extending between the lower and upper cover films.

Electronic system components are becoming increasingly important in the automotive sector. In particular, particular attention should be paid to ensuring a reliable electrical connection between the electronic modules (for example, an electronic transmission control module located in the oil pan for an automotive transmission). The electrical connection between the circuit board with electronic and electromechanical components and the external connection technology (so-called "AVT"), which is usually located within the electronic component module, is variously implemented by a bonding wire, which is inserted into the housing of the module. Electrically connect the connection points of the circuit board to the inserted connection pins. The connecting pin is often connected by laser welding to a lead frame which is "AVT", the web of the lead frame being removed later. The circuit board has the electronic circuit is a printed circuit board that is configured in the upper or so-called "LTCC" (low temperature co-fired ceramic: "L ow- T emperature- C ofired- C eramic") - may be a hybrid.

DE 10 2005 044 482 A1 discloses a flexible flat ribbon line with a plurality of electronic component assemblies spaced evenly spaced thereon. In order to protect the electronic component assembly or to protect the contact area between the electronic component assembly and the flat ribbon line, each electronic component assembly is encapsulated within the housing. However, undesirably in this configuration, after the electronic component assembly is mounted on the flat ribbon line, the functional inspection of the module and / or the preliminary inspection for aging cannot be implemented regardless of cabling.

Electrical connection devices are known for contacting electronic component modules in electrical lines, in particular in flexible flat lines with a plurality of strip conductors extending between the lower and upper cover films, wherein the electronic component modules are embedded in a plastic housing. One or more circuit boards. According to the invention the electronic component module comprises one or more contact plates, in particular one or more flat pins, wherein the contact plates are electrically conductively connected to the circuit board using one or more connection points, the electrical lines being It can be inserted between the one or more contact plates and the housing protrusions with little restraint force and the one or more contact plates can be deformed to form an electrically conductive connection.

The connection device according to the invention is basically a plurality of encapsulated electronic component modules and a plurality of types (eg, cables with one or more electrical conductors, extruded multipole flat ribbon lines, and a plurality of sides covered with (insulated) film). Suitable for forming an electrical connection between flexible (film) flat lines comprising thin strip conductors. However, the following detailed description applies primarily to forming electrical contact between the flexible flat line and the electronic component module, which is resistant to harmful surroundings. Although the connecting region of the flat line to be contacted with the electronic component module can be inserted with almost no restraint force between the housing protrusion used as the support and the contact plate, the contact plate is mechanically deformed through the deformation process to the strip conductors whose exposed side is exposed. They are fixed in contact with them, providing a secure electrical connection. The contact plate can only be deformed after the flat line has been inserted, preferably by bending all the contact plates upwards with a suitable tool until the contact plate is brought into contact with the strip conductor by the defined pressing force inside the recess of the lower film. have. The housing protrusion in this case is used as an upper support for a flat line or for a contact plate pressed from below against the flat line. Therefore, in order to ensure perfect electrical contact, a plurality of recesses must be formed in the lower cover film of the end side connection area of the flat line.

In order to increase the contact pressure formed in the form of dots, small ridges are provided at the ends of the contact plate, which can each be inserted into one or more recesses located in the lower cover film.

Preferably the ridges are connected to the contact plate in a material-bonded and electrically conductive manner by a connection point to further increase contact safety. The material bonded connection point can be formed by a thermal bonding method, for example laser soldering or laser welding. Preferably, in order to simplify the manufacturing process of the electronic component module, each of the plurality of contact plates in the central region is integrated into one contact plate strip by insert injection molding with plastic material. In addition, the contact plate strip may comprise a groove through which one or more edge regions or outer edges of the circuit board may be inserted, preferably by weak pressure bonding. Moreover, the contact plate strip can surround the circuit board in the form of a frame so that the flat line can be connected to the electronic component module at the front face. In the manufacture of electronic component modules, the circuit boards can be adhered to the optional base plate with high thermal conductivity, for example using a thermally conductive adhesive. The base plate is used on the one hand to secure the electronic component module to the motor vehicle and on the other hand to cool the electronic components on the circuit board causing high thermal output losses. Subsequently, one or more contact plate strips are oriented with respect to the circuit board and the contact plates are connected to the connection points on the circuit board by the connection points. Instead of a direct material bonded connection between the contact plate and the connection point on the circuit board, for example, a bonding wire may be provided. The connection point on the circuit board is connected to the electronic and / or electromechanical components on the circuit board by (copper) strip conductors. Electrical contact between the contact plate strip and the circuit board is preferably implemented in a temporary substrate tool. In a subsequent method step, the circuit board, the optional base plate and the electrically contacted contact strips are inserted into a suitable forming tool and insert injection molded at the front face with the electrically insulating plastic compound to form the plastic housing. The two parts are preferably formed of the same plastic material or the same plastic compound in order to integrate the contact plate strips in the plastic housing so as to be mechanically maximally fixed. As the plastic material, in some cases, fiber-reinforced thermoplastics as well as duroplastics are considered. Contact plates or flat pins are formed of a metallic material having an electrically good conductivity, which also has a high mechanical strength. By insert injection molding of the circuit board into the plastic material at the front face, the electronic component module can be sufficiently resistant to extreme environmental conditions.

According to a second embodiment of the electrical connection device, the electronic component module according to the invention comprises at least one elastic contact plate, in particular at least one flat pin, wherein the contact plate is electrically conductive to the circuit board using connection points. Electrical lines can be inserted force-fit between one or more contact plates and the housing protrusions, and electrically conductive connections are formed between the contact plates and the electrical lines. The elastic contact plate provides a reliable electrical contact between the contact plate and the exposed electrical line in the area. If the electrical line is a flexible flat line (“FPC”), the flat line is inserted between the housing protrusion and the one or more elastic contact plates, and then between the strip conductor of the one or more recessed areas of the lower cover film and the contact plate. Electrical contact is formed. Moreover, the spring force of the contact plate already fixes the position by inserting a flat line between the housing protrusion and the strip conductor, which reduces further optional manufacturing steps. In order that the desired contact pressure between the contact plate and the strip conductor can act in the form of a point as maximum, preferably at the end side of the contact plate each is provided with at least one ridge upwardly in the direction of the housing projection, which is one of the lower cover films. It can be inserted into or locked into the recess above. The distance between the contact plate and the housing protrusion is preferably smaller than the material thickness of the flat line in the connection region of the flexible flat line so that a defined insertion force and consequent sufficient contact pressure between the contact plate and the strip conductor are reached. same. In order to further improve the electrical contact safety, one connection point each having electrical conductivity is provided between the ridges of the contact plate and the strip conductor, which connection points are formed using known thermal bonding methods. Corresponding to the first embodiment, the contact plates are insert injection molded from insulating plastic material in the central area to form the contact plate strips.

For mechanical stabilization, an end member can be provided in the connection area of the flat line. The end member has two or more locking members, the locking members snap-in in recesses in the plastic housing formed to complement each other at least with respect to the locking member. In addition, the lower part may be provided under the end member to encapsulate the connecting area in the front face. The two parts can be glued, pressed, clamped or thermally joined, for example. If the connecting device is located in the oil pan of the internal combustion engine, it is not necessary to encapsulate the connecting area with respect to the surrounding oil in a closed manner. Rather, the oil must flow through the area to prevent harmful prolonged precipitation. For this purpose, openings or bores should be provided not only in the end member but also in the lower part, which allow the oil to flow freely, but in metal cutting debris, metal wear, which always occurs when operating in the engine and / or transmission The ingress of water and / or production residues is ensured to a noncritical minimum to prevent short circuits between the contact plates. For example, if the distance between the contact plates is 0.1 mm, the bores of the end member and / or the lower part should be chosen much smaller than 0.1 mm so that a short circuit is reliably prevented. The end member and the lower part of the end bonsai form a short circuit protection in a combined manner while simultaneously exhibiting a flat line tension relief and / or twist prevention. The end member and the lower portion can be formed as an integrated component. In this case, in the region of the lower part, there must be a bore large enough to allow the laser beam, which is generally used to form the connection point between the strip conductor and the contact plate inside the electric flat line, to be guided through. In addition, one or more cavities must be provided such that the ridges of the contact plates penetrate. The end member and the lower part can also be applied to the first embodiment of the connecting device. Moreover, tools can be used to minimize the mechanical forces required for the insertion of the electric flat line. In this case the flat line can be inserted by simultaneously bending all of the participating contact plates by means of a tool, downwardly by a length value at least approximately corresponding to the height of the ridge of the contact plate. The electronic component module herein may be electronic and / or electromechanical circuitry and / or sensors and / or actuators well known in the art. Two embodiments of the electrical connection device according to the invention connect not only an electronic component module to a flexible flat line (so-called "FPC") but also to connect an extruded flat ribbon cable and another multipole electrical cable to said module. Suitable and provided for this purpose.

The connecting device 10 comprises in particular an electronic component module 12 and a flexible flat line 14 inserted into the electronic component module 12. The circuit board 16 is integrated in the plastic housing 18 formed by insert injection molding of the circuit board 16 into the plastic material at the front face. In the plastic housing 18 is integrated a single strip of contact plate 20 with a plurality of contact plates (one of which contact plates 22 are shown) preferably arranged side by side. . Electronic components on the circuit board 16, not shown, are electrically conductively connected to the contact plates 22 inside the plastic housing 18 by connection points 24. The contact plate 22 is here implemented as a so-called flat pin. The internal connection point 24 can be formed for example by laser welding or laser soldering. Between the housing protrusion 26 and the contact plate 22 a connection region 28 of the flexible flat line 14 can be inserted with almost no restraining force, in which case a reliable electrical contact is not yet established at first. The flat line 14 comprises a plurality of strip conductors extending parallel to one another and a strip conductor 30 of one of the strip conductors is shown. The strip conductors are covered by the lower and upper cover films 32 and 34, the lower cover film 32 being provided with a recess 36 and the ridges of the contact plate 22 facing upwards in the recess. (38) is engaged or locked. This allows the flat line 14 to be fixed in position to the electronic component module 12. The strip conductor 30 is exposed in the region of the recess 36. In addition, the contact plate strip 20 has a groove 40 having a rectangular cross-sectional geometry, which allows the contact plate strip 20 to be mounted on the circuit board 16 under the formation of a weak pressure bond. The contact plate strip 20 can be exactly oriented with respect to the circuit board 16. This makes it easy to form a connection point between the contact plate and the circuit board and insert injection molding the entire structure from the plastic material to form the plastic housing 18. The contact plate 22 is preferably formed of an electrically conductive metal alloy that can be easily deformed. Preferably, in order to improve the adhesion, the contact plate 22 is mechanically, chemically and / or physically surface treated, for example by a plasma beam method. Between the ridge 38 and the housing protrusion 26 so that the flat line 14 can be inserted generally without restraint between the housing protrusion 26 and the contact plate 22 or the ridge 38 of the contact plate. The distance (not shown) corresponds approximately to the thickness of the two cover films 32, 34, including the material thickness of the flexible flat line 14, i.e. the thickness of the (copper) strip conductor 30 in the form of a film.

2 shows a sectional view of the connecting device 10 according to FIG. 1 with a flat line in electrical contact.

In order that a reliable electrical contact is formed between the strip conductor 30 and the ridge 38 of the contact plate 22, the contact plate 22 is first deformed in the direction of the white arrow 42 while the prescribed force is used, ie The contact plate is fixed in contact with the flat line 14 and bent upward until the flat line is pressed against the housing protrusion 26 which is a support. In this case, the ridge 38 raises the effective contact point pressure. In addition, the ridge 38 and strip conductor 30 are further optimized to further optimize electrical contact and to prevent the flat line 14 from escaping from the electronic component module 12 (in tension relaxed state). Are provided between them. The connection point 44 is formed by, for example, laser soldering or laser welding.

3 shows a second embodiment of an electrical connection device in which a flat line is inserted into an electronic component module while a force is used.

The connection device 50 includes an electronic component module 52 connected to the flexible flat line 54. The circuit board 56 is integrated in the plastic housing 58. Similarly, the contact plate strip 60 is an integrated component of the plastic housing 58 and has a plurality of contact plates, of which one contact plate 62 is shown. Electrical contact between the circuit board 56 and the contact plate 62 is also performed by the connection point 64 formed by laser welding or laser soldering point. The distance 66 between the contact plate 62 and the housing protrusion 68 corresponds substantially to the material thickness 70 of the flat line 54. The contact plate 62 also has a section beyond the ridge 72 towards the flat line 54 and a displacement 74 connected to the right. In order to insert the connecting region 76 of the flat line 54 in the direction of the arrow 78, the spring-elastic contact plate 62 must be bent downward in the direction of the arrow 80 using mechanical force. The force required for this may be up to 30N. This can be done, for example, using a suitable tool, not shown, which engages in the displacement 74. Flat line 54 includes a plurality of strip conductors, of which one strip conductor 82 is shown. Both sides of the strip conductors are covered with lower and upper cover films 84 and 86. The lower cover film 84 has a recess 88 in the connection region 76, in which the strip conductor 82 is exposed. After the flat line 54 is completely inserted between the housing protrusion 68 and the contact plate 62, the contact plate returns to its original position after the force action ceases (see in particular FIG. 4). This causes a clamping action between the upwardly raised ridge 72 and the housing protrusion 68, thereby establishing a reliable electrical contact between the electronic component module 52 and the flat line 54. The contact plate 62 is formed of a metal alloy having good spring characteristics and at the same time having electrical conductivity. Preferably, the contact plate 62 is suitably surface treated to improve adhesion in the plastic housing 58 or contact plate strip 60.

4 shows an electrical connection device 50 with an inserted flat line and material-coupled connection points.

Since the contact plate 62 returns to the starting position of the contact plate, the ridge 72 is pressed by the mechanical force defined against the strip conductor 82 exposed by the recess 88 in the region. . The housing protrusion 68 is then used as a support for the spring force starting vertically upward from the contact plate 62. As the ridge 72 is locked into the recess 88, the flat line 54 is protected from exiting in an uncontrolled manner from the electronic component module 52 immediately after insertion. In order to further optimize the electrical contact, the region of the ridge 72 is provided with a connection point 90 formed by a known joining method. This further connects the material 72 between the ridge 72 and the strip conductor 82 in a materially coupled manner, indicating reliable electrical contact even under disturbing ambient influences. The thermally bonded connection point 90 prevents the flat line 54 from exiting the electronic component module 52 in an uncontrolled manner even at high force action and / or high acceleration.

5 to 7, which are simultaneously referred to by the following detailed description, show three possible embodiments of the bulge of the contact plate 62 in a heavily enlarged perspective view.

5 shows a view of the ridge 72 according to FIGS. 3 and 4, which has an almost hemispherical geometry. 6 shows a ridge 92 having a shape almost corresponding to the shape of a truncated cone, whereas the ridge 94 of the contact plate 62 according to FIG. 7 is embodied in a waveform. In particular, the truncated conical ridge 92 ensures a large contact area between the contact plate 62 and the strip conductor using an almost flat top surface, while the other two embodiments utilize point contact with high surface pressure. To form.

8 is an enlarged plan view of a flat line 54 with different recesses in the lower cover film.

The recess 88 of the lower cover film 84 of the flat line 54 is formed in a circular shape. The strip conductor 96 extending to the right away from the strip conductor 82 has a rectangular recess 98 and the width of the recess, not shown, is slightly smaller than the width of the strip conductor. Respective rectangular recesses are located in the region of additional strip conductors, not shown, the widths of the recesses almost correspond to the widths of the strip conductors, the recesses being the flat line 54 of the lower cover film 84. Extends to the end of the Based on the exemplary embodiments of the recesses shown in FIG. 8, a number of other geometric configurations of the recesses may also be considered.

9 to 11, which are simultaneously referred to by the following detailed description, show a connecting device 50 having an end member and a corresponding lower portion disposed in the connecting region of the flat line.

Unlike the drawings according to FIGS. 3 and 4, in this embodiment the connection region 76 of the flat line 54 is, among other things, an end member used for mechanical stabilization of the flat line 54 in the connection region 76. Having a 100 and a lower portion 102, upsetting of the very thin flat line 54 is usually prevented, especially when the flat line is inserted into the electronic component module 52. The circuit board 56 is electrically conductively connected to the contact plate 72 by the connection point 64 and together with the contact plate 62 or the contact plate strip not shown in this embodiment, the plastic of the electronic component module 52. It is integrated in the housing 58. The end member 100 has an almost U-shaped cross-sectional geometry with lower and upper legs 104, 106, and preferably the connecting region 76 of the flat line 54 is formed while a weak press fit is formed. It is inserted between the legs. The two legs 104, 106 extend substantially parallel to each other at a distance not shown. The lower leg 106 has a cavity 108 so that the ridge 72 of the contact plate 62 can pass freely. The ridge 72 abuts against the strip conductor 82 which opens downward in the region of the recess 88 due to the spring force of the contact plate 22, and at the same time an electrical contact is formed by this contact. . To further increase electrical contact safety, the ridge 72 is materially connected to the strip conductor 82 using the connection point 90. Lower portion 102 has an almost L-shaped cross-sectional geometry with long legs and short legs 110 and 112, which legs meet each other at an angle of approximately 90 °. In the region of the front section 114 of the lower leg 104, the end member 100 and the lower portion 102 are connected to one another, for example glued, clamped or welded. Alternatively, the end member 100 and the lower portion 102 may be formed of some material. End member 100 and lower portion 102 may be made of the same insulating plastic material, such as plastic housing 58 or contact plate strip 60. End member 100 and its lower portion 102 may be bonded, welded, or sprayed onto flat line 54 in such a way that mechanical stabilization is further enhanced. If the end member 100 and the lower portion 102 are formed in part, the long legs 110 are provided with one or more bores 116, and the laser beam necessary for the formation of the material-bonded connection point 90 is provided. It can penetrate the bore. If the end member 100 and the lower part 102 are implemented in part, preferably they are already fixed on the connection area of the flat line 54 at the time of manufacture. After thermal bonding, the bore 116 may be closed with a plastic material. In this member embodiment there is no need to provide a bore 116 because the lower portion 102 is assembled to the end member 100 only after the connection point 90 is formed. If the end member 100 and the lower portion 102 consist of some material, the displacement portion 74 of the contact plate 62 becomes unnecessary, in which case it is necessary to approach the tool to bend the contact plate down. Because it is not possible. In addition, a plurality of additional bores, not shown in the end member 100 as well as in the lower portion 102, may be provided in addition to the bore 116. This allows the fluid (eg oil) surrounding the connecting device 50 to flow freely, thereby preventing the formation of harmful, in particular conductive deposits inside the end member 100 and the lower part 102 for a long time. In this case, the bores preferably have a diameter selected slightly smaller than the electrically conductive particles (eg metal cutting debris, metal wear or manufacturing residues) that may be contained in the surrounding fluid, so that the electrical connection area 76 is prevented. The particles can reliably fall far from or from the contact plate. If the distance between the contact plates is, for example, 0.1 mm, the bores should have a much smaller diameter so as to reliably block the contaminants. The end member 100 is provided with a tapered portion 117 so that the flat line 54 is easily inserted. 10 shows a plan view of the connecting device 50 cut along the cutting line X-X, but the plastic housing 58 of the electronic component module 52 is not shown. In order to enhance the electrical insulation effect, two ribs 118, 120 are provided between each adjacent two contact plates of the lower portion 102. The number of ribs should always be one more than the number of contact plates provided in the electrical connection device. 11 shows a schematic plan view of a connecting device 50 having a plastic housing 58 of an electronic component module 52 and a flat line 54 inserted according to FIG. 9. In order to implement tension relaxation, the end member 100 preferably has two or more locking members sprayed on both sides in an integrated manner, in which only the upper locking member is shown and indicated by reference numeral 122 in FIG. have. The locking member 122 is snapped in or locked in the recess 124 of the plastic housing 58 of the electronic component module 52. For this purpose the geometry of the recess 124 is at least partially complementary to the geometry of the locking member 122.

The connection devices 10, 50 according to the invention provide, among other things, an electrical and reliable contact between the electronic component module and the electrical line or cable, in particular between the cables in the form of thin flexible flat lines with strip conductors composed of copper film. Provided to form. In both embodiments the connecting devices 10, 50 ensure reliable contact with long term stability even under extreme ambient conditions, which are common for example in oil pans of internal combustion engines or automotive transmissions.
