Definitions

  • the invention relates to an electrical connector with contact elements arranged in contact chambers, spring legs of the contact elements provided with an embossed contour being arranged in mirror image.
  • Such connectors are used as circuit board connectors.
  • the aim is to increase the number of contact elements of a connector more and more, but to reduce the size of the connector itself. So that two-leg spring contact elements can be produced economically even with small grid spacings of ⁇ 2 mm, it is necessary to punch them out of a continuous metal strip in the respective mounting grid. Due to the resulting narrowness of the distances, however, it becomes difficult to make the contact on both sides, since the handling no longer fits into a small stamping grid in conventional contact elements with a U-shaped or folded contact body. This is particularly true for connector designs for surface mounted technology (SMT), in which the size of the surface mount device (SMD) is kept very flat and very small and the number of contacts can hardly be reduced. In addition, the plug force of the connector increases with an increasing number of contacts.
  • SMT surface mounted technology
  • a connector for printed circuits which has spring legs arranged in mirror image in its contact chambers with an embossed contour, the contact elements or whose spring legs are designed such that they are supported on the contact turns in the idle state.
  • the invention has for its object to provide a connector of the type mentioned in such a way that the insertion forces are reduced in spite of constant contact forces and the same number of contacts compared to conventional connectors, wherein when inserting the knife contacts into the contact elements of the contact chambers, first a low contact pressure of the spring legs on the knife contacts is exercised so that a soft insertion of the mating connector is achieved - but at the same time an immediate secure contact is guaranteed - and that the maximum contact forces only act when the knife contacts are fully inserted.
  • the spring legs are designed such that they are at a distance from the contact chamber walls when the contact elements are inserted into the contact chambers, and the spring legs are deflected when inserting a contact pin into the contact elements in such a way that they are supported on the contact chamber walls .
  • the advantages achieved with the invention consist in particular in that the insertion forces of the connector according to the invention are lower than conventional connectors. This is achieved in that the spring legs, due to a longer effective spring length and a narrow spring root, during the insertion of a mating connector (male connector), be deflected with little force. The spring legs are then supported on the contact chamber walls by an appropriately designed contour and, due to a shorter active spring length in connection with the wider contact legs, generate an increased spring force which is necessary for reliable contacting.
  • the plug connection contains a mating connector 2 designed as a male connector, which is soldered to the printed circuit board 4, and a plug connector 1 designed as a female connector which is connected to the printed circuit board 3.
  • one or more row signal contacts (knife contacts) 5 are connected, which are designed as pins and protrude upwards through the bottom 6 of the insulating body 7 of the mating connector 2 (the further configuration of the mating connector 2 is not described in more detail here) interact with a corresponding number of resilient contact elements 8, which are located in recesses of an insulating body 9, with corresponding contact chambers 10.
  • the contact element 8 has a fixed area, the so-called tight fit 11, with which the contact elements 8 are firmly anchored in the contact chambers 10 of the connector 1.
  • a circuit board connection 12 can be seen on the circuit board 3. As shown, this can be carried out using surface-mounted technology (SMT) or using conventional press-fit technology.
  • SMT surface-mounted technology
  • the contact element 8 shown in Figs. 2-5 is provided as a one-piece, two-legged contact spring with a spring leg connection 14 and with mirror-inverted opposite contact tips 15 and is, as shown in Fig. 2, first by continuous punching from a metal band with a narrowed spring root 16 and widened spring legs 13 made. The contact element is then brought into the shape shown in FIGS. 3-5 by embossing.
  • FIG. 6 shows a plug connection in which the knife contacts 5 of the mating connector 2 have not yet been inserted into the contact elements 8 of the connector 1. It can be seen that between the contact chamber walls 18 and the contact legs 13 due to a corresponding contour 17 there is a small distance (B). At the moment of inserting the knife contacts 5 of the mating connector 2 into the contact inlet (KE) of the contact elements 8, the spring legs 13 are deflected laterally with little force, 16 low insertion forces being achieved by the combination of a long effective spring length (l) and a narrow spring root.
  • the plug force curve of the plug connector is plotted over the insertion path in a diagram in FIG. 8. It can be seen that the plug-in force (SH) of a conventional connector has a much steeper course and also greater height than the plug-in force (SN) of a connector according to the invention.
  • Fig. 9 the spring forces of the spring legs of a contact element of conventional design and a contact element / connector according to the invention are shown in a further diagram.
  • the spring force (FH) of the spring legs increases linearly in conventional connectors
  • the spring force (FN) of the spring legs of the contact element / connector according to the invention initially increases with a slight slope and rises steeply when the spring legs rest against the contact chamber walls.
