Definitions

  • the present invention relates to a device according to the Preamble of claim 1, i.e. a PCB zero force connector with one case and two in this housed, pivotable towards and away from each other Connector halves, the connector halves in one the assembly position swung away from each other one of the circuit boards to be connected allow and in a swiveled towards each other Contact the inserted circuit board in the connection position.
  • a device i.e. a PCB zero force connector with one case and two in this housed, pivotable towards and away from each other Connector halves, the connector halves in one the assembly position swung away from each other one of the circuit boards to be connected allow and in a swiveled towards each other Contact the inserted circuit board in the connection position.
  • circuit board zero force connectors are, for example known from US 3 130 351 and serve two Printed circuit boards essentially power-free, electrically and mechanically connect with each other; they become one of them used to make a first circuit board easy and gentle in the essentially perpendicular to a second circuit board (for example a so-called backplane circuit board) to be able to and they are electrically and mechanically firm and to connect reliably with it.
  • a second circuit board for example a so-called backplane circuit board
  • circuit board zero-force connectors should come from this Reason are offered in different lengths, the different lengths, preferably an integer multiple correspond to a base length (for example 25 mm).
  • PCB zero force connectors of different lengths is, however, with a relatively high Effort connected because (preferably on one and the same Equipment) manufactured different sized parts and need to be assembled.
  • the present invention is therefore based on the object the PCB zero force connector according to the preamble of claim 1 so that This is both easy to manufacture and easy to process even if the PCB zero force connector its dimensions can be varied should.
  • each of the connector halves a large number of connector half modules consists.
  • the connector half modules are designed so that they are independent of their location within the PCB zero force connector are constructed identically, so the PCB zero force connector from a minimal Number of different components, namely a varying one Number of identical connector half modules, the housing and a swivel mechanism for swiveling the connector halves apart and together, where it is solely the relatively easy to vary Housing that is worth mentioning to the respective length of the PCB zero force connector must be adjusted.
  • the circuit board zero force connector according to the invention is therefore even with varying dimensions very easy to manufacture.
  • circuit board zero force connector because it is a coherent unit, which in a minimal number of operations and without increased Precision requirements on one of the connected Printed circuit boards can be mounted.
  • the zero force plug connector described in more detail below is designed to be two essentially vertical to be arranged in relation to each other PCBs electrically and mechanically with each other connect to.
  • the application of the circuit board zero force connector according to the invention is not on such Limited applications; the printed circuit boards that are made by circuit board zero force connectors connectable of the type described are, in principle, 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.
  • the PCBs through this PCB zero force connector 1 to be connected are one first circuit board 2 and a second circuit board 3, wherein the first circuit board 2 substantially perpendicular to the second circuit board 3 should be pluggable.
  • Circuit boards in the manner of the second circuit board 3 are, for example so-called backplane circuit boards; the attachable on it Printed circuit boards like the first printed circuit board 2 are common referred to as plug-in cards according to their assembly.
  • FIGS. 1 and 4 there is the PCB zero force connector from a housing 10, a first connector half 11, a second connector half 12 and a swivel mechanism 13, the Connector halves 11 and 12 in turn each from a wide range of connector half modules 110-1 or 110-2 exist.
  • the connector half modules 110-1 and 110-2 are as in FIG Figure 1 shown from the one shown in Figure 1 below Bottom of the housing 10 can be used in this.
  • the completely assembled PCB zero force connector 1 (only the housing 10 of the same in the example considered) is firmly mounted on the second circuit board 3; the first circuit board 2 can then, as in particular from the Figure 4 can be seen through an elongated opening 100 the top of the housing 10 through between the connector halves 11 and 12 are inserted.
  • the elongated opening 100 is dimensioned so that only such Printed circuit boards can be pushed through, at least from their dimensions - no damage to the PCB zero-force connector let fear.
  • the first connector half 11 and the second connector half 12 are (even in the mounted on the second circuit board 3 State of the PCB zero force connector 1) the actuation of the pivot mechanism 13 to a later described in more detail synchronous to each other and swiveling or folding away from each other.
  • This goes in The example considered here is particularly simple and easy because - as already mentioned and more precisely will be described - the connector half modules 110-1 and 110-2 and the second circuit board 3 are not attached to each other are.
  • All connector half modules i.e. both the connector half modules 110-1 of the first connector half 11 as also the connector half modules 110-2 of the second connector half 12 have exactly the same in the example considered Construction.
  • the connector halves have modules a multi-part structure; they exist from an insulating outer part 111, a layer 112 juxtaposed, held together by insulating elements Contact elements 117, an insulating middle part 113, another layer 114 of juxtaposed, contact elements held together by insulating elements 118, an insulating inner part 115 and a Holding part 116.
  • the individual parts mentioned are by a just putting them together and through the holding part 116 held together.
  • the contact elements 117 of the contact element layer 112 and the Contact elements 118 of the contact element layer 114 are elongated electrically conductive elements, about which, how can be seen in particular from Figure 4, contact points the first circuit board 2 and contact points of the second circuit board 3 can be connected to each other; it deals are elastic elements that are relaxed Condition with both ends from the connector half modules 110-1 and 110-2 stand out, with the outstanding ones End sections in the considered example for contacting Surface contacts are designed.
  • PCBs can be connected of which both the one and the other surface contacts have as contact elements to be connected.
  • the conventional PCB zero force connectors and other connectors to be observed at the contact points Signal reflections can be reduced to a minimum be reduced.
  • this also includes assembly of the PCB zero force connector to the second circuit board 3 considerably simplified: it must namely as already mentioned above, only the housing 10 of the PCB zero force connector on the second PCB 3 are attached. Beyond that arise through the use of surface contacts as PCB contact points also in the arrangement and density same more freedoms.
  • Each of the contact elements 117 and 118 passes through the respective one Connector half module in a closed on all sides Channel 119, which is properly in the two circuit boards connecting state of the circuit board zero force connector continuous from the surface of one circuit board extends to the surface of the second circuit board. Thereby can the contact elements 117 and 118 over their entire Length must be completely shielded.
  • the contact elements 117 and 118 can however, do not move along channels 119 because they are by (electrically insulating) connecting parts, which the contact elements of the contact element layers already mentioned Hold 112 and 114 together, or with spacers or by injection molded noses or the like in the longitudinal direction fixed immovably.
  • the contact elements 117 and 118 rather, when it is brought into the connection position bent elastically, but the freedom of movement of the Contact elements due to their structure, shape and their arrangement is so limited that only such movements can take place in which the distance between the contact elements and one or more of the impedance of the connection determining channel walls essentially unchanged remains. This ensures that under all circumstances, i.e. even if the PCB zero force connector and / or the circuit boards to be connected are subject to certain tolerances, always equally high quality connections between those to be connected Printed circuit boards can be produced.
  • the connector half modules designed as described are in the orientation shown in Figures 1 and 4 inserted into the housing 10 from below.
  • the housing 10 is of intermediate length 101 divided into several chambers of the same size. These chambers are dimensioned so that there is a pair of each other opposite connector half modules can be used and that in relation to the longitudinal direction adjacent connector half modules, i.e. the connector half modules forming a connector half can be strung together almost without gaps.
  • the inner parts 115 face each other.
  • the length of the chambers and thus also the length of the connector half modules preferably corresponds to the unit of length, in Steps from which the length of the PCB zero force connector should be variable if necessary.
  • the toggle levers are in the state shown in FIG in a stable (self-locking) position, which they can only leave if the hinge points marked G be moved upwards.
  • the one with her part (Arm) on the housing 10 abutting rods and press by their other arm against the upper sections of the connector halves modules, which turns them into one around the Pins 120 are held pivoted towards each other position.
  • the connection position of the PCB zero-force connector is the one in these inserted first circuit board more or less firmly between the connector halves clamped and properly contacted.
  • the connector halves modules pressed against the second circuit board 3.
  • the said contact elements are namely in the connection position shown in Figure 4 elastically pushed back into the channels 119 and strive in their relaxed position, in which they protrude from channels 119 to return.
  • the connector half modules become - although no connection between them and rods 131 and 132 - automatically to the extent that it is the position change the respective rod allowed to move away from each other pivoted.
  • the rods do not stand with the connector half modules Time in connection; they are separate parts.
  • the manufacture of the housing 10 in different lengths is a relative because of the simple construction of the housing easy task.
  • the production also varies long rods 131 and 132 are very simple and straightforward; they just have to be made long enough and can then easily be cut to any length become.
  • circuit board zero force connector described can also very easy to different thicknesses of those to be inserted into them (First) circuit board to be adjusted. For this only the housing 10 needs to be changed: it must be widened so far that the space between each other opposite connector half modules in their connecting position roughly the thickness of the one to be used in between PCB corresponds. The connector halves require modules in this case, too, no modification whatsoever.
  • the components of the described zero-force circuit board connector can be regardless of its length and Assemble the width into a coherent whole, see above that when processing the PCB zero force connector only one part has to be handled; the Processing is therefore always quick and easy.
