Definitions

  • the present invention relates to a circuit board zero force connector according to the preamble of Claim 1.
  • 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 simple 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.
  • PCB zero force connectors have long been in a variety of performance forms are known; a PCB zero force connector the in the preamble of the claim 1 claimed type is for example in US-PS 3 853 379.
  • the 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 by actuating an actuator in a allowing the insertion or removal of a circuit board Installation position, and by inserting a circuit board can be brought into the connecting position.
  • the actuator is a rod that runs parallel next to a circuit board guide with the help of which with the PCB zero force connectors to be connected or connected to this circuit board to this or can be led away from it.
  • the pole protrudes with one Swivel lever over the rear one with regard to the insertion direction Edge of the same so far that they are always freely accessible and is operable, together with the circuit board guiding device firmly mounted on the exception circuit board is.
  • the present invention is therefore based on the object the PCB zero force connector according to the preamble of claim 1 so that the actuator even with a mechanically relative weak training of the same reliably under all circumstances is protected from damage and deformation.
  • the actuator can thereby directly on parts of the Circuit board guide device and / or the circuit board to be carried close. This provides the actuator on the one hand, a smaller contact surface for external forces on this, and on the other hand it is through the Circuit board guide device and / or the circuit board supported laterally.
  • the integration of the actuator in the circuit board guide device also has the positive effect that the actuator has a (swivel) mechanism of the Printed circuit board zero force connector that is available to the PCB zero force connector from the mounting position in the connection position and / or vice versa bring, reached at a central location, whereby this can be formed symmetrically.
  • a symmetrical one Structure of the swivel mechanism allows it to move from this forces exerted on the actuator partially cancel and / or that asymmetrical loads on the actuator be avoided, causing the on the actuator acting forces or at least their negative ones Side effects can be reduced to a minimum.
  • the actuator of the circuit board zero force connector according to the invention is therefore mechanical even with one relatively weak training of the same reliably Damage and deformation protected.
  • the trained as claimed and arranged actuator due to its integration in the PCB guiding device that is normally present anyway no longer an obstacle for the Airflow for PCB cooling. This is particularly so for printed circuit boards attached to backplane circuit boards of considerable importance, because the attached circuit boards are sometimes so close together that a sufficient Cooling is becoming more and more complex and difficult anyway becomes.
  • the zero force plug connector described in more detail below is designed to be essentially vertical to be arranged in relation to each other PCBs electrically and mechanically with each other connect to.
  • the application of the invention PCB zero force connector is not on, however limited such applications; the circuit boards that go through PCB zero force connectors of the type described can be connected, basically any relative positions take in.
  • the zero force plug connector described in more detail below is denoted in the figures by the reference number 1.

  • PCBs 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 according to their assembly referred to as plug-in cards.
  • the PCB zero force connector 1 is in use a mounting plate 2 fixed on the second circuit board 4 mounted. Thereby the PCB zero force connector 1 and the second circuit board 4 both mechanically as well as electrically firmly and reliably connected.
  • the circuit board zero force connector 1 contains in his Inside two connector halves 11 (hidden in the figures) and 12 separated by an elongated slot 13 are.
  • the first connector half 11 and the second connector half 12 (even on the second circuit board 4 assembled state of the PCB zero force connector 1) by actuating one on the side of the PCB zero force connector 1 provided, but not in the present case pivot mechanism 14 to each other and described can be pivoted or folded away from each other.
  • circuit board guiding devices 5 On two opposite sides of the PCB zero force connector 1 are circuit board guiding devices 5 provided, with the help of which (between which) the first circuit board 3 defines in or out of the slot 13 of the PCB zero force connector 1 is feasible; in the Figures is just one of the PCB guiding devices 5 shown.
  • This circuit board guide device, designated by reference number 5 is by means of mounting plates 6 and 7 on the housing accommodating the arrangement shown or Frame mountable, with the housing or the frame in the Figures is not shown.
  • an element designated as an actuator 8 used in this which also serves as a guide element the PCB guide device 5 and as an actuator to actuate the pivot mechanism 14 of the PCB zero force connector 1 is used; although this is not the case in the example considered here each of the circuit board guiding devices with one or similar actuator 8 may be equipped.

  • 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 along when used as intended the pivot 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 circuit board zero force connector 1 caused becomes.
  • the engagement between the end portion 82 of the actuator 8 and the swivel mechanism 14 is designed that these elements at least either in the assembled position or in the connection position of the PCB zero force connector 1 not connected stand (detached from each other); the actuator 8 can be completely independent of the PCB zero force connector 1 at any time together with the PCB guide device 5 or without this in the Arrangement used or removed from this.
  • 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 of the actuator 8 in the longitudinal direction facilitate and / or by inserting / removing one Coordinate circuit board (the circuit board 3).
  • the move of the actuator 8 can also without Using the folding part 85 or the like performed become.
  • 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 mounting position brought into the connection position or vice versa shall be.
