Definitions

  • the invention relates to a connector comprising a first connector element with a plurality of signal pins and a second connector element with a plurality of counter-signal pins, which are designed such that in the plugged state the signal pins are inserted into the counter-signal pins, wherein the first connector element has a first shielding means and the second connector element has a second shielding means, which make electrical contact with one another in the plugged state.
  • a connector is understood to be a shielded plug connection with a shielded socket and a shielded plug.
  • the plug has signal pins that can engage in contact forks, the mating contact pins of the socket.
  • a generic connector is, for example, from the DE 10 2005 059 990 B4 known.
  • Such connectors have two plug-in connection elements that can be brought into mutual engagement. They have a large number of electrically conductive contacts for establishing electrically conductive connections.
  • Such connectors are used in particular for SMD connectors ("surface-mounted device") and are attached to circuit boards.
  • SMD connectors surface-mounted device
  • One of the two plug-in connection elements is attached to one circuit board and the other of the two plug-in connection elements is attached to another circuit board.
  • the plug connections are used in this way to electrically connect different circuit boards.
  • the EP 2 351 163 B1 shows an angle connector with a shield and a method for producing the shield of the angle connector.
  • the first shielding means comprises a first sheet metal stamping from which a plurality of shielding springs are machined and each shielding spring is divided into a first shielding spring and a second shielding spring, which extend longitudinally to a plug-in direction, wherein the first shielding spring has a first contact point bent into the first shielding spring and the second shielding spring has a second contact point bent into the second shielding spring, wherein the second shielding spring is designed to be shorter than the first shielding spring and as a result the contact points contact the second shielding means at different points in the plug-in direction.
  • This type of connector shielding ensures that a very low-impedance ground connection is created between the components connected by the connectors.
  • a ground connection that is optimized in terms of interference can be achieved by combining a certain ratio of signal pins to ground pins in conjunction with the shielding or the optimized ground connection in the connector. Both the inherent interference immunity and the external interference immunity are improved because the shielding plates also serve as a ground connection.
  • Another advantage of this arrangement is that a contact sequence can be maintained, because the now split shield spring and the special design of the shielding contact between plug and socket not only achieves a very low shielding inductance or coupling inductance, but at the same time a defined contact sequence is maintained, so that the shielding or ground contacts first and only then the signals.
  • the new type of shielding contact with split shield springs creates contact on two levels. First the contact is made via the shielding, i.e. a ground contact, only then does the signal pins contact. This sequence must be maintained, otherwise the connected electronic components could be destroyed.
  • the first plug connection element has a first housing part in which the plurality of signal pins and the first shielding means are arranged, the first shielding means having the first sheet metal stamping part and a further second sheet metal stamping part, wherein the sheet metal stamping parts are arranged in an edge region of the first housing part parallel to the plugging direction and have a soldering side for a circuit board and a contact side for contacting the second shielding means, wherein the sheet metal stamping part is designed on the soldering side with soldering feet for soldering onto the circuit board and the respective first contact point is arranged closer to the contact side and the respective second contact point is arranged closer to the soldering side.
  • the contact position of the shield spring was moved towards the soldering points. This makes the path from the contact point of the shield to the circuit board as short as possible.
  • the upper half makes the first contact. Only then do the signal pins make contact.
  • the lower half realizes the short signal path with which the low shield inductance is achieved.
  • the improved "shield inductance" was demonstrated by measurements. compared to the connectors according to the state of the art.
  • the connector or transition contacts are further optimized by having a recess in the first and/or second curved contact point.
  • the recess creates a defined "elevation" with which a point contact is achieved. Since the springs are always slightly twisted due to manufacturing tolerances, without a recess there would be a continuous, wide, uniform shape. Then you cannot say exactly where the actual contact point is. However, if you deliberately create a "elevation", the contact point will also be at the "elevation”.
  • first shield spring and the second shield spring are bent out of the plane of the stamped sheet metal part. This creates a spring force and improves contact.
  • the second plug connection element has a second housing part in which the plurality of counter-signal pins and the second shielding means are arranged, the second shielding means is essentially flat and arranged parallel to the plugging direction such that the first shielding means can be pushed over the second shielding means.
  • the first shielding means has an expansion-bending, which is realized by the end of the contact side of the sheet metal stamping being angled by an opening angle of approximately 45 degrees.
  • the connector according to the invention enables the realization of high-quality shielding.
  • a homogeneous and very low inductance coating is achieved within the connector.
  • This connector particularly suitable for the transmission of high-frequency signals.
  • a digital signal can be transmitted with a data rate of up to 10 gigabits with high quality, while at the same time ensuring a high level of signal integrity.
  • the connector is therefore particularly suitable for signal processing arrangements in which, for example, circuit boards are to be connected to a backplane.
  • a plug connector 10 comprising a first plug connection element 1 with a plurality of signal pins 3 and a second plug connection element 2 with a plurality of counter signal pins 4, which are designed such that in the plugged state the signal pins 3 are inserted into the counter signal pins 4, wherein the first plug connection element 1 has a first shielding means 1SM (see also FIG 3 ) and the second plug connection element 2 has a second shielding means 2SM, which electrically contact each other in the plugged state.
  • the first plug connection element 1 has a first housing part 11, in which the first shielding means 1SM is arranged in an edge region RB in such a way that soldering feet LF protrude on the upper side.
  • the second shielding means 2SM are arranged in a second housing part 12; here too, soldering pins protrude downwards for fastening to a circuit board.
  • the first shielding means 1SM comprises a first sheet metal stamping part 5 and a second sheet metal stamping part 5'.
  • FIG 3 shows the connector 10 from FIG 1 without the first housing part 11 and without the second housing part 12.
  • the arrangement of the first shielding means 1SM above the second shielding means 2SM is now clear.
  • the second shielding means 2SM comprises a third sheet metal stamping part 6 and a fourth sheet metal stamping part 6'.
  • FIG 4 once again shows how the first sheet metal stamping 5 rests on the second sheet metal stamping 6 for ground contact.
  • a plurality of shield springs SF are machined out of the first sheet metal stamping 5 and each shield spring SF is divided into a first shield spring SF1 and a second shield spring SF2.
  • FIG 5 a detailed representation of the first sheet metal stamping 5 is shown.
  • the first and second shield springs SF1, SF2 extend lengthwise to a plug-in direction SR.
  • the first shield spring SF1 has a first contact point K1 bent into the first shield spring SF1 and the second shield spring SF2 has a second contact point K2 bent into the second shield spring SF2, wherein the second shield spring SF2 is designed to be shorter than the first shield spring SF1 and as a result the contact points K1, K2 contact the second shielding means 2SM at different points in the plug-in direction SR.
  • the contact position of the second contact point of the second shield spring SF2 was moved in the direction of the soldering points for the soldering feet LF. This makes the path from the contact point of the shield to the circuit board as short as possible.
  • the first shield spring SF1 or the first contact point K1 makes the first contact to ground during a plugging process in the plugging direction. Only then do the signal pins 3 make contact with the counter-signal pins 4.
  • the second shield spring SF2 creates a short signal path, with which the low coupling inductance is achieved because the second contact point K2 is arranged closer to the soldering side LS.
  • a recess A is arranged in the first and second curved contact points K1, K2.
  • the recess A creates a defined "elevation" with which a point contact is achieved. Since the springs are always slightly twisted due to manufacturing tolerances, without a recess you would have a continuous, wide, uniform shape. Then you can't say exactly where the actual contact point is. But if you deliberately add a "raised area", the contact point will also be at the "raised area”.
  • FIG 6 shows the first sheet metal stamping 5 in a side view and the first shield spring SF1 and the second shield spring SF2 are bent out of the plane of the sheet metal stamping 5 by a bending angle ⁇ .
  • An expansion offset AK is realized in that the end of the contact side KS of the sheet metal stamping 5 is angled by an opening angle ⁇ of approximately 45 degrees.
  • the FIG 7 shows the connector 10 without housing parts 11,12 in a sectional view.
  • the first and second sheet metal stampings 5,5' are each arranged with their soldering feet LF on a first circuit board 21.
  • the third and fourth sheet metal stampings 6,6' are each arranged with their associated soldering feet on a second circuit board 22.
  • a contact sequence is also maintained. This is because the now split shield spring SF and the special design of the contact of the shield between plug and socket not only achieves a very low shield inductance, but at the same time a defined contact sequence is maintained, so that first the shield or the ground and only then the signal pins 3 contact their counter-signal pins 4.
  • the new type of contact of the shield with split shield springs creates contact on two levels. First the contact is made via the shield, i.e. a ground contact, only then does the contact of the signal pins occur. This order must be followed, otherwise the connected electronic components may be destroyed.
