Definitions
- the invention relates to an arrangement with a circuit board, which is provided with at least one conductor track and a contact element for establishing an electrical connection between an electrical conductor and a predetermined conductor track on this circuit board.
- a predetermined conductor track which is located on a circuit board, with an external electrical conductor mechanically and electrically safely.
- This electrical conductor can, for. B. serve for power supply, and in this case, no interruption of the power supply may occur in the operation of the vehicle.
- This connection can also be used to connect to the electric motor of a safety-relevant application, e.g. B. with a motor that is controlled from the circuit board. That can e.g. B. be an application in which a movement is electrically controlled (x-by-wire).
- a reliable connection is required over the entire service life of the motor vehicle, aircraft, ship or the like.
- the invention provides a reliable mechanical and electrical connection between the printed circuit board and the contact element, since the legs fit into the recesses in the PCB are pressed in (press-in technology). These recesses are electrically connected via their metallization to the conductor tracks of the printed circuit board and the circuit located there, and they are electrically and mechanically connected to the legs of the contact element by being pressed in. The latter in turn enables a reliable connection to the electrical conductor coming from outside.
- the contact element is thus already electrically connected to the specified conductor track by the press-in technique, and in addition a flat solder joint is obtained between it and the conductor track.
- a soldered connection between the contact element and the conductor track is thus established, i. H. when the circuit board is heated in the reflow oven, the solder can get to any desired location.
- these soldered connections also form a secure electrical connection and support the mechanical connection created by the pressing. Despite cost-optimal processes, this provides a high level of functional reliability of the connection between the contact element and the printed circuit board / conductor track, namely electrically and mechanically.
- the focus is on creating a connection that is very secure and reliable and therefore has a certain redundancy.
- FIG. 1 is a plan view of a circuit board on which there is a conductor track and which is provided with holes according to a predetermined pattern
- FIG. 2 shows a top view analogous to FIG. 1, in which a contact element according to a first exemplary embodiment of the invention is fastened on the printed circuit board 20 and is electrically connected to the conductor track,
- FIG. 3 shows a section, seen along the line III-III of FIG. 2
- 4 shows a section, seen along the line IV-IV of FIG. 2nd
- FIG. 5 shows a preferred variant of FIG. 3,
- Fig. 6 is a spatial representation of a simplified contact element according to a second embodiment of the invention.
- FIG. 7 shows a circuit board with the contact element of FIG. 6.
- Fig. 1 shows a circuit board 20 on which there is a conductor track 22, which usually consists of tinned copper.
- a conductor track 22 which usually consists of tinned copper.
- Three bores 24, 26, 28 are provided above the conductor track 22 in FIG. 1, and two bores 30, 32 below it.
- the five legs 34, 36, 38, 40, 42 of a contact element 44 are pressed into these five bores 24 to 32.
- the contact element 44 usually consists of a copper alloy, or of copper, brass or the like.
- the conductor track 22 is largely adapted to the shape of the contact element 44 in order to enable large-area soldering.
- the legs 34, 36, 38 preferably have an identical shape.
- the leg 38 has a free end 37, and it has a reduced width 39 in the region of this free end 37, so that it can be easily inserted and pressed into the opening 28 when the printed circuit board 20 is fitted.
- the leg 38 has a width 41 which is dimensioned such that it has to be pressed into the opening 28, i. H. its width 41 exceeds the diameter D (FIG. 1) of the bore 28, so that a press fit is obtained during assembly, which results in a good mechanical connection.
- the bores 24 to 32 are metallized at least at one end, e.g. B. with copper to get a good press-fit connection and thus a good mechanical and also electrically conductive connection.
- the contact element 44 can have three legs 34, 36, 38 on its upper side in FIG. 2 and two legs 40, 42 on its lower side. All legs are electrically and mechanically connected to a base part 46, which looks like an inverted U in FIG. 2 and has two legs 48, 50 and a base 52 which connects these legs. But it can also be just one or two legs.
- a spring tongue 54 is punched out between the legs 48, 50 and is formed in one piece with the base 52 at its upper end in FIG. 2.
- the spring tongue 54 has on its left part in FIG. 3 a section 56 at which it rises sharply and which merges into a slowly falling section 58, which leads to a contact point 60 and from there slowly rises again at 62, so that in Fig. 3 forms an insertion opening on the right, into which a dash-dotted sheet metal part 66 can be inserted, z. B. for electrical connection to a (not shown) motor, which is to be controlled from the circuit board 20, or for connection to a power supply or to any device.
- the base part 46 has left and right cheek 70 and 72, respectively.
- the cheek 70 is formed on the leg 48, the cheek 72 on the leg 50.
- These cheeks 70, 72 serve as lateral guide members for the sheet metal part 66 during its assembly.
- the printed circuit board 20 is printed with solder paste at the required points. Subsequently, the contact element 44 is pressed into the printed circuit board 20, a portion of the solder paste reaching recesses 49 in the contact element 44 and being stored in these recesses.
- the electronic components SMD components
- the circuit board After pressing in, the electronic components (SMD components) are placed in the usual way on the previously printed solder paste, and after this has been done, the circuit board is transported through a reflow oven, where the soldering of all components takes place.
- the conductor track 22 is adapted to the shape of the contact element 44, as can be seen directly from a comparison of FIGS. 1 and 2. Large-area soldering is thus achieved.
- continuous recesses 49 are provided in the base part 46, into which the solder paste is partially pressed during this press-in process, so that sufficient solder paste to be used in the reflow oven Is available to get a proper solder joint. These recesses 49 thus serve as a reservoir for the solder paste.
- the contact element 44 is soldered in the reflow oven in the usual manner.
- solder 74 flows into the openings 24 to 32 and also flows under the base part 46 by capillary action, as a result of which this is soldered to the conductor track 22 over a large area. This creates an additional mechanical connection to the circuit board 20.
- the connection arrangement 44 is electrically securely connected to the conductor track 22.
- the sheet metal part 66 for the electrical connection can, for. B. have a width of 0.8 cm. It preferably has a recess into which a wart or the like provided on the spring tongue 54 snaps into place in order to enable secure mechanical locking between the spring tongue 54 and the sheet metal part 66, which is also useful during assembly.
- the sheet metal part 66 is attached to two lateral areas, e.g. at points 76, 78, non-contact welded by welding using a laser (so-called laser spots).
- a laser so-called laser spots.
- the welding results in a material connection from the contact element 44 to the sheet metal part 66, that is to say a very safe and reliable electrical and at the same time mechanical connection.
- FIG. 5 shows a variant of FIG. 3. Parts which are the same or have the same effect as in FIG. 3 are therefore designated with the same reference symbols.
- a disadvantage of FIG. 3 may be that a gap is formed between the contact element 44 and the printed circuit board 20 during assembly, which gap could hinder the formation of a secure soldered connection.
- the reason is that the legs 34 to 42 are in the right Angles are bent downwards, whereby inevitably a bending radius arises which can cause the gap described when pressed in.
- the variant according to FIG. 5 enables the contact element 44 to rest on the printed circuit board 20.
- the legs are first bent up and then bent through 180 °. This is illustrated using the example of the legs 34 'and 40'.
- the leg 34 ' is bent upwards at the point 57, then makes a bend by 180 ° at 59, the radius of this bend possibly being chosen to be very small, and from there it goes vertically downward at 61.
- the same shape, but mirror image, is found in the leg 40 '.
- FIG. 6 shows a spatial representation of a contact element 80, approximately on a scale of 10: 1, which is constructed similarly to the contact element 44 of FIGS. 1 to 5, but has only four legs. It has a base part 82 with two longitudinal legs 84, 86 which are connected on one side by a base 87. Two legs 88, 90 are bent from leg 84 and two legs 92, 94 from leg 86.
- a resilient contact tongue 96 is punched out and shaped in the manner shown in order to insert an electrical conductor, for. B. a flat metal part, and to hold this flat metal part securely in the inserted position.
- FIG. 7 shows the fastening of a sheet metal strip 66 serving as an external electrical conductor to the contact element 80.
- the latter is fastened on a printed circuit board 20 in the manner described above, the conductor track 22 (cf. FIG. 1) not being shown here for simplification.
- the contact element 80 with its four legs 88, 90, 92, 94 is in corresponding recesses of the circuit board soldered.
- the sheet metal part 66 is inserted between the base part 82 and the resilient tongue 96.
- the latter has a wart 97 on its side facing sheet metal part 66, the hollow upper side of which is visible in FIG. 7.
- the sheet metal part 66 has a corresponding recess (not shown), and if it is inserted correctly, the wart 97 engages in this recess and thereby holds the sheet metal part 66 captively.
- the sheet metal part 66 is then welded to the base part 82 by laser spot welding in its area designated 100 in FIG. 7. The same happens preferably on the opposite side, not visible in FIG. 7. In this way, an extremely reliable electrical and mechanical connection is obtained, which can be easily automated.
- the attachment to a circuit board 20 is carried out in the same manner as that described for the first embodiment in FIGS. 1 to 5, i. H. by means of a press fit in holes in the printed circuit board, as shown in FIG. 7, and additionally by means of corresponding soldered connections.
- the legs 88, 90, 92, 94 can have a slightly reduced width at their free ends in order to simplify assembly in the holes in the printed circuit board.
- connection from a conductor track of the circuit board to an external electrical conductor has two components: a) The connection from the conductor track to the contact element. b) The connection from the contact element to the external conductor.
- connection component a obtains its security through the combination of a press-in process, which primarily brings about a mechanical but also an electrical connection, with a soldering process in which the low-resistance electrical connection is in the foreground, but also a mechanical connection is produced.
- connection component b) obtains its security by welding the flat conductor to the contact element, the snap-in of the conductor and the spring force on the contact tongue causing additional redundancy and facilitating assembly.
- the invention provides an electrical connection of great security that it enables the conductor track of a circuit board to be safely and reliably connected to an external component in which high currents flow, e.g. B. with an electric motor.
- This secure and reliable connection is made possible by a press-in connection between the printed circuit board and the contact element and by a soldered connection to the conductor track 22, and by the welded connections 76, 78 produced in a contactless manner, as described in FIG. 2.
- the assembly is extremely simple and can be automated without any problems, which is also facilitated by the snapping between the sheet metal part 66 and the spring tongue 54.
