Definitions

  • the present invention relates to a connector for Backplane wiring consisting of one that is open on one side right-angled housing trained male connector for Attach to the knives of a backplane and one insertable into the male connector with receiving chambers provided and firmly connected to an assembly circuit board Female connector, with the knives and contact springs parallel in several rows are arranged, the individual contact springs are surrounded by electrically conductive shield plates, which in the intermediate grid both on the back side and contacts on the assembly side are connected, that have a corresponding potential applied to them.
  • From US-A-5 162 001 is a connector with knives and contact springs known in which the contact springs are arranged in receiving chambers of a metal block are. There they are switched centered in sleeve-like plastic housings.
  • the connector has a complicated manufacture Building on.
  • the object of the present invention is to specify a connector of the type mentioned at the beginning, whose high-frequency properties meet the requirements suffice, and which is characterized by a relatively simple Structure distinguished.
  • This task is for a connector of the type mentioned Art solved in that the female connector housing continuous receiving chambers exist in the metallic Pipes are inserted, and that in the pipes with plastic overmolded contact springs are inserted in such a way that their center conductors is mounted centrally to the pipe, the extrusion coating begins on the assembly side and ends in the rear spring area.
  • the connector according to the invention offers connector passages, which are much smaller and cheaper than conventional mini-COAX connectors and regarding the transmission properties meet all today's requirements.
  • the connector is characterized in that the contacts from both in the backplane wiring board as well as in the assembly circuit board using press-fit technology firmly anchored contact pins exist in the inserted state each pressed into a wire mesh are in the recesses provided between the hands of the tubes is appropriate. That way is a very good one Screen derivation guaranteed in the intermediate grid.
  • Another expedient embodiment is characterized in that that the ends of the tubes at four diagonally opposite Places cut out essentially in a circular arc are, the uncut sections of the Serve shield contacting.
  • the cutouts will Flow behavior of the stream improves, it becomes a vortex formation and thus largely avoided additional resistance.
  • the female connector 1 is shown in the main.
  • the female connector 1 is located between a backplane 2 a subrack and a subassembly board 3 an assembly.
  • the female connector is only indicated in Fig. 1.
  • the male connector 1 consists essentially of a Plastic body with a large number of receiving chambers. The individual chambers go from side to side and are separated from each other by plastic partition walls 6 Cut.
  • Metallic tubes 4 can be inserted into the receiving chambers. into which contact springs 5 overmolded with plastic 12 in such a way are inserted that the center conductor is mounted centrally to the tube 4 is.
  • the encapsulation begins on the assembly side and ends in the rear spring area, to the spring properties of the contact spring 5 fully receive.
  • the receiving chamber can avoid the contact spring with the pipe on the back a spring leg stop 7 for the Have contact spring. This spring leg stop 7 serves at the same time as an inlet funnel 8 for the contact blades 14.
  • the metallic tubes can be round as well have a square cross section.
  • the contacting of the metallic pipes 4 with an earth or shielding potential takes place via contacts in the diagonal, i.e. in the grid. With conventional connectors this grid is 1.25 mm.
  • the earth or shield potential contacts are in the housing on the module side firmly anchored and are in the assembly circuit board in the already known press-in technology. In the backplane is also an appropriate contact intended. As shown in Fig. 3, the contacting done with the tubes 4 in three different ways.
  • a first way of contacting is that a tuft connector 9 using press-fit technology in the circuit board is firmly anchored and protrudes into the recess 13.
  • Another type of contacting is that in the Recess introduced a wire mesh or contact wool is and firmly anchored in each of the plates contact pins 10 are. When plugged in, these contact pins 10 protrude in the wire mesh 11 or in the contact wool.
  • Another way of contacting is that a wire mesh or one introduced into the recesses Contact wool is made directly on the contact surfaces of the printed circuit boards. This solution saves one press-in process.
  • Fig. 5 shows schematically a top view of an assembly circuit board 3, the openings 15 for the contact springs 5 and the openings 16 for the shield contact pins are recognizable.
  • 4 is a rear view from above shown on a female connector 1 and several partially Cuts in section planes A, B and C.
  • the tailpipes essentially at four diagonally opposite points cut out in a circular arc, such that the non-cut ones Sections form the boundary of the recess, i.e. serve as shield contact.
  • This will, according to the Fluid dynamics improves the flow behavior of the current. Through this constructive measure a vortex formation and thus largely avoiding additional resistance.
