Definitions

  • the innovation relates to a contact element for the electrical connection of a conductor to at least one printed circuit board.
  • Contact elements for connecting a conductor to contact pads are known in a large number of embodiments.
  • a tap that has two lugs on each side into which a circuit board can be inserted.
  • a screw contact is provided on a third side, so that the inner conductor of a cable can be inserted into the tap and can be fastened with the screw contact.
  • the approaches are soldered to the associated contact pads of the circuit board in a soldering process.
  • This tap has the disadvantage that it is relatively complex to assemble and requires additional screw connections.
  • a contact element is also known (DE-OS 33 01 361), which consists of a tulip-shaped contact spring with diametrically arranged holding legs.
  • the contact element is connected electrically and mechanically to a printed circuit board by soldering using the holding legs.
  • the known contact element has the disadvantage that the holding legs have to be soldered and that there is no guidance of the contact element when it is applied to the printed circuit board.
  • the innovation is based on the task of creating a contact element for the electrical connection of a conductor with at least one contact pad on a printed circuit board, which has small dimensions, is easy to assemble and is also suitable for solderless connections.
  • the contact element has a sleeve-shaped base body with a square cross-section, which at one end merges into at least two spring arms opposite one another with a predetermined distance and at its other end into at least two contact tabs provided with constrictions, it can on the one hand with the spring arms onto the circuit board can be pushed, with the circuit board between the spring arms, and on the other hand, the Inner conductor of a cable are inserted into the tabs, the necessary voltage for the electrical connection being predetermined by the constrictions of the contact tabs. Since no screw connections are necessary, the contact element can be made very small, the short connection between the contact points of the spring arms with the contact surfaces and the cable giving only small inductances. Since no soldering has to be provided due to the spring arms, the contact element cannot be contaminated by flux, for example during wave soldering, as a result of which the electrical connection would be impaired, but it is possible to push the contact element onto the printed circuit board later.
  • the contact element 1 according to FIGS. 1 to 3 has a sleeve-shaped base body 2, which has a rectangular cross section.
  • the base body 2 merges into spring arms 3 which face each other and form a distance between them which is approximately smaller than the printed circuit board with the corresponding contact pads 15 (Fig. 4).
  • the spring arms have teeth that help improve contacting.
  • the spring arms 3 are provided with incisions 5, as a result of which each spring arm 3 is divided into two partial arms 6. This improves the spring action of the spring arms and gives the possibility of a larger number of contact points.
  • the base body 2 is slotted at the four corners, so that there are four tabs. According to FIG.
  • two opposite tabs each serve as contact tabs 7 and as guide tabs 8.
  • the contact tabs are first bent inwards and then obliquely outwards, so that a constriction 9 results.
  • the guide tabs 8 are also bent outwards.
  • FIG. 3b the base body 2 has four contact tabs 7, the constrictions 9, 9a of which are axially one behind the other in pairs.
  • the contact element is bent from rolled sheet metal, so that a longitudinal slot 11 is present due to the manufacturing process.
  • This longitudinal slot is arranged such that it divides a contact tab 7 in the middle, so that two partial tabs 12 result. This measure will Contacting the contact tab 7 with the inner conductor of the cable improved, since three contact points are available.
  • FIG. 4 shows a contact element 1 provided with a cable 13, which is pushed onto a printed circuit board 14 with contact spots 15.
  • a slot 16 is provided in the circuit board, with the contact pads 15 beginning near the end of the slot.
  • the width of the slot 16 in the printed circuit board corresponds approximately to the width of the contact element 1, while the thickness of the printed circuit board 14 corresponds approximately to the distance between the projections 10. In this way, lateral guidance as well as guidance in height is made possible.
  • the slot widens somewhat, so that the guide tabs 8 can also serve to guide the contact element 1.
  • the teeth 4 of the spring arms 3 claw into the contact spots 15, so that a good electrical connection is given.
  • the inner conductor 16 of the cable 13 is merely inserted into the contact element, the contact tabs 7 pressing apart somewhat and the constrictions 9 lying on the inner conductor under tension.
