Definitions
- the invention relates to a device for the electrical and mechanical connection of two printed circuit boards with the features specified in the preamble of independent claim 1.
- Such a device is known, for example, from the article “flexibly connecting printed circuit boards” in Feintechnik & Meßtechnik 1991, pages 204-205 and comprises electrically conductive contact pins which are electrically connected to the conductor tracks of a rigid printed circuit board.
- the contact pins are perpendicular to the rigid one
- the end of the contact pins protruding from the rigid circuit board is passed through an opening in each case of an elastically flexible film circuit board and is soldered to the conductor tracks provided on the back of the film circuit board.
- the device advantageously consists of two easy-to-manufacture parts.
- a considerable ease of assembly results from the fact that a first, preferably elastically flexible circuit board can be securely fastened to a second circuit board in a few simple steps by using the clamping part and the contact pin interacting therewith.
- the device is very robust and reliable and advantageously forms a strain relief for the second printed circuit board when the first printed circuit board is subjected to vibrations and shaking due to the elastic flexibility.
- the clamping part and the contact pin can be produced inexpensively using simple techniques.
- a particularly reliable fixing of the clamping part on the contact pin is achieved in that the clamping part has a recess for the implementation of the contact pin, from the inner edge of which claw-like projections extend towards the contact pin and clasp it on all sides.
- the recess is surrounded by an annular section of the clamping part is which section on its outer edge facing away from the recess is bent back towards the recess such that the underside of the bent-back section forms an annular contact area of the clamping part for bearing on the first printed circuit board. Due to the bend, the support area is movable against the ring-shaped area and always lies flat against the conductor track of the first circuit board.
- the clamping part has a circumferential groove and that the clamping part can be fixed in the opening of the first printed circuit board such that the inner edge of the opening engages in the circumferential groove.
- the clamping part can be preassembled on the first printed circuit board, which considerably simplifies assembly.
- the first circuit board can be clamped in the circumferential groove, so that the clamping part is reliably electrically connected to a conductor track surrounding the opening of the first circuit board.
- section bent back towards the recess is bent back again in such a way that a further section bent back extends approximately parallel to the contact area of the clamping part, the section bent back towards the recess and the further section bent back simultaneously the side walls of the circumferential groove form.
- the side of the further bent back section facing away from the circumferential groove advantageously forms a second contact area of the clamping part for contact on the second printed circuit board.
- the contact pin has lateral grooves extending in the axial direction for engaging the elastically flexible projections of the clamping part, which are formed closed at their end facing away from the second circuit board.
- the grooves enable a reliable clasping of the contact pin, the closed ends of the grooves forming latching edges, behind which the elastically flexible projections of the clamping part engage barb-like in the grooves. Accidental detachment or jumping off of the clamping part is advantageously avoided.
- the force-fitting contact of the elastically flexible projections on the contact pin advantageously causes force to be applied to the support area, so that the support area is firmly pressed against the conductor track of the first printed circuit board.
- the clamping part can advantageously be formed in one piece.
- the clamping part is a stamped and bent part made of sheet metal.
- the clamping part is also conceivable to design the clamping part as an elastically flexible plastic part, which is provided with an electrically conductive coating.
- FIG. 1 shows a cross section through the device according to the invention with two printed circuit boards
- FIG. 2 is a top view of FIG. 1.
- Fig. 1 shows the electrical and mechanical connection of two circuit boards by means of the device according to the invention.
- a first circuit board 1 which can be an elastically flexible circuit board, for example a foil circuit board.
- foil circuit boards consist, for example, of a polyimide foil strip on which thin conductor tracks 10 made of copper are applied, which are covered with an insulating material coating.
- the film circuit board 1 has circular openings 5.
- conductor tracks 10 with annular end portions 10 v surround the edge of the opening 5 on the top of the film circuit board 1. Above the annular portion 10 ⁇ of the conductor tracks 10, the insulation is removed, so that this section 10 ⁇ from outside contactable.
- a second rigid circuit board 2 is provided on its top with an electrically conductive contact pin 3 made of metal, for example.
- the contact pin 3 is electrically connected to a conductor track, not shown, of the second circuit board 2. This can be done by soldering, riveting, an electrically conductive adhesive or in another form.
- the contact pin 3 protrudes perpendicularly from the top of the printed circuit board 2 and has a substantially cylindrical shape.
- the diameter of the contact pin 3 is made smaller than the inside diameter of the opening 5 of the first circuit board 1.
- the outer surface of the cylindrical contact pin 3 is provided with four grooves 13 extending in the axial direction, the end of the grooves 13 facing away from the second circuit board 2 being closed is trained.
- the clamping part 4 is formed in this embodiment as an elastically flexible, one-piece stamped and bent part made of metal. However, it is also possible to manufacture the clamping part 4, for example, as an elastically flexible plastic part which is connected to an electrically conductive coating is coated.
- the clamping part 4 has an annular section 17, in the middle of which a recess 20 is made. As shown in FIG. 2, four projections 14 protrude from the inner edge of the essentially circular recess 20 towards the center of the recess 20.
- the projections 14 are formed in a jagged manner with sharp-edged tips protruding towards the center of the circular recess 20. In the exemplary embodiment shown here, the projections on the inner edge of the recess 20 are diametrically opposite.
- the outer edge of the ring-shaped section 17 facing away from the recess 20 is bent back in cross section downward by approximately 180 °, a section 18 extending towards the recess 20 adjoining the bend 21.
- the underside of the annular section 18 forms a support area 15 for support on the first printed circuit board 1.
- the bent-back section 18 is provided at its end facing the recess 20 with a further bend 22 which is followed by an annular section 19 directed away from the recess 20.
- the annular sections 17, 18, 19 connected to one another via the bends 21, 22 form an S-shaped contour.
- the annular sections 18 and 19 connected to one another via the bend 22 furthermore form a circumferential groove 16, in which the edge of the opening 5 of the printed circuit board 1 engages.
- either the elasticity of the foil conductor plate 1 can be used, or else the clamping part 4 is inserted into the opening 5 with the section 19 not yet bent, and then the section 19 around the opening 5 is bent around like a flange. This can be done so that the support 15 of the clamping part 4 is firmly pressed against the annular end 10 v of the conductor 10, so that the clamping part 4 is electrically conductively connected to the conductor 10.
- the procedure is then such that the contact pin 3 of the second circuit board is first pushed through the opening 5 of the first circuit board 1 and then through the recess 20 of the clamping part 4.
- the elastically flexible projections 14 first spread back at the end of the contact pin facing away from the second printed circuit board 2 and finally engage with their pointed ends behind the latching edges 12 of the grooves 13 in a barb-like manner in the grooves
- the second printed circuit board 2 is electrically contacted with the first printed circuit board 1 via the contact pin 3, the projections 14 and the support area 15.
- the projections 14 can only engage behind the locking edges 12 after the annular section 19 of the clamping part 4 has already come into contact with the second printed circuit board 2.
- the projections 14 must then be pressed manually in the direction of the second printed circuit board in order to hook behind the locking edges 12. This can be achieved in that the section 19 is biased against the second printed circuit board 2 and the support area 15 against the conductor track 10 of the first printed circuit board, since the projections 14, which bear against the latching edges 12 under prestress, then bring about a force introduction onto the support area 15.
- the clamping part acts
- the circumferential groove 16 can also be dispensed with.
- the first circuit board 1 then lies directly on the second circuit board 2. In this case, it is then necessary for the support area 15 of the clamping part 4, as described above, to be biased against the conductor track 10 by the elastic force of the elastically flexible projections 14, since otherwise there is no reliable electrical contact.
- the axial grooves 13 formed on the contact pin 3 with the latching edges 12 can also be omitted if the clamping force of the projections 14 is sufficient to press them firmly against the contact pin 3. If the contact pin 3 is made of a softer material than the clamping part 4, the projections 14 can claw into the contact pin with their sharp-edged tips.
