Definitions

  • the invention relates to a contact strip for printed circuit boards arranged in sandwich construction, with an insulating body and a number of contact elements arranged therein at grid spacing x, each of which has a bearing section for fixing it in the insulating body and two to be contacted with the mutually facing conductor tracks of the printed circuit boards Has contact leg.
  • the invention is based on a contact strip, which is not documented in more detail, and which has an insulating body which is held in the lower of the two printed circuit boards with plug pins.
  • the contact piece has a C-like shape in the broadest sense in the side view. The apex of the upper C-curvature rests under the upper circuit board, while the leg emerging from the bottom of the housing represents a soldering foot for SMT ('Surface Mounting Technique).
  • SMT Surface Mounting Technique
  • the object of the invention is to provide a contact strip of the type outlined in the preamble of claim 1, in which the contact elements can be introduced into the insulating body in a relatively simple manner and are held therein.
  • Another object of the invention is to design the contact elements of the contact strip in such a way that, despite considerable miniaturization of the arrangement, in particular up to grid spacings of only about 0.5 mm, they ensure the necessary contact spring forces of the contact legs over long operating times.
  • the present invention is characterized in that the bearing section is designed as a tongue which can be inserted into an insulating housing slot and points in the same direction as the contact legs and is arranged between them.
  • the contact element For the secure reception and fixing of the contact element in the insulating body, only the insulating body slot is provided there. This can be co-generated in the injection molding production of the insulating body for the contact strip.
  • a tongue is formed between the contact legs and can be inserted into the insulating body slot.
  • the contact element which thus essentially has an E-shape in the side view, from the side in the longitudinal direction of the forwardly pointing bearing section into the corresponding receptacle of the insulating body.
  • taped contact elements are supplied to the insulating body and all poles are simultaneously attached to the insulating body at least in a pre-fixed manner.
  • a particularly advantageous further embodiment consists in that the bearing section is arranged laterally by a grid spacing x next to the plane defined by the contact legs. This configuration makes it possible to cut out the two contact legs and the tongue-like bearing section from a flat material and to deform them into the specific spatial shape.
  • the contact legs which also have a tongue shape, and the bearing section start from a central one Area of the contact body and all extend in the same direction, but the bearing portion is adjacent to the plane that is defined by the contact legs lying in the same plane.
  • the feature according to the invention of the arrangement of the bearing section by a grid spacing x to the side next to the contact limbs leads, in connection with a further embodiment, which is characterized by the arrangement of the contact elements in the insulating body in opposite directions from pole to pole, in that the bearing section of a contact element at one location in the insulating body anchored can be located in the plane of the contact leg of the immediately adjacent contact element.
  • the contact strip can also be designed such that at least one of the two contact legs of the contact elements is designed as SMT solder pins, with which the entire contact strip would be anchored to the conductor tracks of one circuit board by soldering the solder pins, whereas the second circuit board to the opposite one resilient contact leg of the contact elements would be pressed.
  • a contact strip can also be used without soldering contact legs by simply being placed between two mutually parallel printed circuit boards and being held there essentially purely by pressure.
  • flanking alignment means in order to always, e.g. under the influence of vibrations, to safely avoid that the relative position of the contact elements to the conductor tracks could involuntarily change.
  • the alignment means can also serve as spacers for the printed circuit boards by e.g. in the form of strips or frames, are attached to the side of the contact strip or surround it and hold the circuit boards connected to one another by clamping or fastening means at an exact distance.
  • the contact elements are held with their tongues self-anchoring in the insulator body slots, for which purpose these tongues e.g. may have barbed or claw-like edge notches.
  • the insulating body is preferably designed as a one-piece injection molded part.
  • FIGS. 1 and 5 only the outline of the insulating body 11 and the mutually opposite sides of the insulating body 11 projecting beyond the outline of contact legs 12, 13 and 12 ', 13' are shown in FIGS. 1 and 5.
  • These contact legs are under an outwardly directed spring tension, so that they engage between two circuit boards 15 and 16 arranged parallel at a distance 14 in a force-fitting or pressure-locking manner on their associated conductor tracks 17 and 18.
  • the two printed circuit boards 15 and 16 which in the functional state have, for example, a clear distance of only 3 mm or less, are held in parallel in a sandwich-like manner by means not shown.
  • spacers 19 are shown schematically, due to their tightly flanking the contact strip 10 as a support body, ensure that the contact strip, which is only held in a pressure-locking manner via its contact elements 12, 13, 12 ', 13' between the plates, reliably maintains its intended position with respect to the conductor tracks.
  • the contact legs designated by 12 and 13 in FIG. 4 belong to a different contact element than those designated by 12 'and 13'. This is easy to understand on the basis of the illustration in FIG. 6.
  • the view shows that a contact element 20 essentially has the shape of the letter E.
  • the two outer legs of the E are the contact legs 12 and 13.
  • a third, rectilinear leg as the bearing section 21.
  • This bearing section 21 is punched out of the same flat sheet of contact metal, in particular beryllium bronze, and is only bent over, as are the contact legs 12 and 13.
  • the bearing section 21 is connected to the material strip 23 via a short transition section 22 connected, from which the two legs 12 and 13 are punched out and deformed.
  • the bearing section 21 comes into a plane that lies laterally next to the plane of the contact legs 12 and 13, namely by a distance x that corresponds to the grid or pole distance of the contact strip.
  • the insulating body 11 is an injection molded component made of a very dimensionally stable material that has practically no shrinkage.
  • the insulator has a number of thin webs 24 which are integrally connected to one another by means of core sections 25 which are smaller in outline.
  • core sections 25 which are smaller in outline.
  • two such core sections 25 lie close together to form a slot 26.
  • This slot 26 is thus an insulating body slot into which a contact element 20 with its bearing section 21 is inserted from one of the two possible sides and then held firmly therein.
  • this bearing section 21 is located laterally next to the contact sections 12, 13 of the same contact element 20. Consequently, in FIG. 4, the contact element with 20 'arranged in the same plane as the bearing section 21 of the contact element 20 and its contact leg with 12' and 13 ' designated.
  • This contact element 20 ' is inserted with its bearing section, which is not visible in FIG. 4, from the other side into the adjacent insertion space.
  • This comb-like intermeshing of bearing sections 21 of one contact element 20 between the contact legs 12 'and 13' of the respectively adjacent contact element 20 ' enables a very high packing density or number of poles per unit length to be achieved.
  • the contact strip 10 which is shown in FIG. 5, differs from the previously described contact strip 10 essentially only with regard to its contact legs 13 or 13 ', which emerge downwards in the drawing and which are designed as SMT soldering feet aligned parallel to the conductor track 18 are. 5, the upper circuit board 15 is still shown at a distance. In the operational state, however, it is so close to the lower circuit board 16 that the contact legs 12 and 12 'of the relevant contact elements 20 and 20' bear on the conductor tracks 17 under their own spring pressure.
  • the tongue-shaped bearing sections 21 are each self-anchored in the insulating body slots 26.
  • the tongues 21 have edge edge formations 27 of approximately the type recognizable in FIG. 6, which can claw into the plastic material of the insulating body 10.
  • an alternative is also within the scope of the invention, which in turn uses the basic E-shape in the view of a contact element 20, but in which, for example by folding, the bearing section 21 would lie in the same plane as the contact legs 12 and 13 4 shows that it would then also be possible to anchor a contact element in an insulating body slot 26 with its central bearing section. In this case could, should however, the contact elements cannot be connected to the insulating body 11 from different sides.
  • contact legs 12 and 13 project freely, because only the central tongue is held on the insulating body. This ensures excellent spring properties and contact forces.
  • the contact strip 10 can be made in very small dimensions, for example with grid spacing x of approximately 0.5 mm and for a printed circuit board spacing 14 of less than 3 mm.
