Definitions

  • the present invention relates to a device according to the Preamble of claim 1, i.e. a PCB zero force connector with one through an actuator actuatable swivel mechanism, the actuation of which PCB zero-force plug-in connector from one plugging in or removing a printed circuit board Installation position in a properly contacting the circuit board Connection position and / or vice versa is.
  • PCB zero force connectors serve two Printed circuit boards essentially power-free, electrically and mechanically connect with each other; they will among other things used to make a first circuit board easy and gentle essentially perpendicular to a second circuit board (for example a so-called backplane circuit board) to be able to do it electrically and mechanically to connect firmly and reliably with it.

  • the printed circuit board zero-force connector known from this publication is firmly connected to one of the other PCBs to be brought in and designed to that the other of those to be connected Printed circuit boards can be inserted into these. It is built that it operates on a swivel mechanism acting actuator in a plugging or removing a printed circuit board assembly position, and by inserting a circuit board in the connection position is feasible.
  • the actuator is a Rod that is parallel next to a circuit board guide runs, with the help of which with the PCB zero force connector to be connected or connected to this circuit board to this or can be led away from it.
  • the said rod must be so it can serve its purpose through the in-board zero force connectors inserted circuit board, more precisely said about the rear edge with respect to the insertion direction they protrude so far that they (the pole) always is freely accessible and operable. It must for this reason have a considerable length, making them prone to damage and deforms, especially since it is actuated of the swivel mechanism to be transmitted via the rod Forces can become remarkably large at least for a short time. If you wanted to damage and deform the rod reliably exclude, you could be stable accordingly form. This would make the arrangement disproportionate become expensive and unwieldy.
  • the present invention is therefore based on the object the PCB zero force connector according to the preamble of claim 1 so that its Actuator even with a mechanically relative weak training of the same reliably under all circumstances is protected from damage and deformation.

  • the PCBs through this PCB zero force connector 1 to be connected are one first circuit board 3 and a second circuit board 4, wherein the first circuit board 3 substantially perpendicular to the second circuit board 4 should be pluggable.
  • Circuit boards in the manner of the second circuit board 4 are, for example so-called backplane circuit boards; the attachable on it Printed circuit boards like the first printed circuit board 3 are common referred to as plug-in cards according to their assembly.
  • the PCB zero force connector 1 is in use a mounting plate 2 fixed on the second circuit board 4 mounted.
  • the PCB zero force connector 1 and the second circuit board 4 both mechanically as well as electrically and reliably connected.

  • the actuator is essentially one in the example considered rod-like element (a push and pull rod), which in a printed circuit board guide device is integrated with Help which defines the first circuit board 3 in the or from the slot 13 between the connector halves 11 and 12 is feasible.

  • the actuator 8 has in the middle part 81, i.e. except for its two end portions 82 and 83 one essentially U-shaped cross section.
  • the middle part 81 is dimensioned so that it is in the circuit board guide 5, more precisely said a designated free space of the same way can be used that the actuator 8 is freely displaceable in the longitudinal direction, otherwise but pretty little freedom of movement within the Has PCB guide 5; the circuit board guide 5 and / or the actuator 8 and / or the mounting plates 6, 7 are designed so that the Actuator 8 against falling out and / or Pull out of the PCB guide 5 is or can be secured.
  • the assembled zero-force connector 1 facing end section i.e. the one with the Reference numeral 82 designates end portions of the actuator 8 comes, as will be described in detail when used as intended with the Swivel mechanism 14 engages that by actuation, i.e. a movement of the actuator 8 in the longitudinal direction opening and closing the connector halves 11 and 12 of the Printed circuit board zero force connector 1 is effected.
  • the assembled from the PCB zero force connector 1 opposite end section, i.e. the one with the Reference numeral 83 designates end portions of the actuator 8 protrudes over a in the PCB zero force connector 1 inserted circuit board, more precisely on the with respect to the insertion direction of the rear edge thereof and is in the example considered with a two-armed Provide lever-like folding part 85.
  • This in the present Folding part 85 serves to move it to facilitate the actuator 8 and / or with inserting / removing a circuit board (the circuit board 3) coordinate. Moving the actuator 8 can, however, also without the aid of the folding part 85 or the like can be performed.
  • the displacement of the actuator 8, i.e. a pushing or pushing it to the PCB zero force connector 1 or pulling it away from the PCB zero force connector 1 must be done when the PCB zero force connector 1 from the Installation position in the connection position or vice versa to be brought.

  • the actuator 8 of this be pulled away.
  • the guide devices of the swivel mechanism 14 exist in the example under consideration from groove-like depressions 142 and 147, which are on freely accessible side surfaces of two independently movable swivel mechanism parts 141 and 146 are provided and away from the edge thereof, for example run inward as shown in the figures; the guide devices of the actuator 8 exist in the example under consideration from two in the end section 82 of the same provided pins 821, which consist of opposite one another Protruding surfaces.
  • the groove-like depressions 142 and 147 as well as the pins 821 are arranged and designed so that they are against each other or are feasible.
  • the actuator 8 and to be moved by this Swivel mechanism parts 141 and 146 are separate, i.e. parts not firmly connected; they are designed that they are in the assembly position of the PCB zero force connector 1 are detached from each other.
  • the Actuator 8 can be completely independent of the circuit board zero force connector 1 at any time together with the circuit board guiding device 5 or inserted or removed from the assembly without them will.
  • the pivot mechanism 14 and the actuator 8 more precisely said the groove-like recesses 142 and 147 of the pivot mechanism parts 141 and 146 and the pins 821 of the actuator 8 are arranged and designed so that the Pins 821 upon reaching swivel mechanism parts 141 and 146 by the actuator 8 on the edge of the Swivel mechanism parts 141 and 146 ending portions of the groove-like depressions 142 and 147 and automatically run into them automatically.
  • the pins 821 can namely neither the course of the groove-like depressions 142 and 147 follow (the actuator 8 and thus also the pins 821 are only in the longitudinal direction of the actuator displaceable), the groove-like depressions 142 and 147 leave, so that it inevitably the groove-like depressions 142 and 147 and the swivel mechanism parts containing them 141 and 146 are those of the movement of the Pins 821 must follow.
