Definitions

  • the present invention relates to a connector with board.
  • D-sub filter connectors which have a housing in which a plurality of plug contact pins are arranged.
  • the housing In the housing there is a circuit board.
  • the board is provided with holes through which the plug pins extend.
  • the plug pins are soldered to the board.
  • On the board a capacitor is provided for each plug contact pin, which is to filter the guided by plug pins electrical signals.
  • the board is mechanically and electrically connected to the housing by means of a solder joint. Since the housing is connected to ground, this solder joint forms the ground connection for the board.
  • Such filter plug have been proven in practice, as they can be filtered with interference signals.
  • the integration of a circuit board in such a miniaturized connector is problematic because such a board is sensitive to mechanical stress. When plugging a significant proportion of the insertion forces is absorbed by the board. These insertion forces lead to damage to the board and damage to the solder joints between the Plug contact pins and the board or between the board and the housing. The life of these connectors is therefore limited.
  • the plug contact pins are surrounded by a strip body.
  • the strip body is designed as a filter element. It consists of a mixture of insulating material and ferrite material. This strip body forms an electrical inductance for filtering unwanted high frequency signals. This generates EMC protection.

  • the US 4,950,185 discloses another connector having a housing, a receiving body for receiving contact pins.
  • the contact pins extend through the plate-shaped ceramic capacitor arrays. These arrays are formed of a plate-shaped ceramic material in which electrically conductive electrodes are embedded.
  • the contact pins are electrically connected to the electrodes by means of contact springs.
  • These capacitor plates are surrounded by a ground electrode. This grounding electrode may be electrically connected to the grounded housing by means of contact springs.
  • the DE 199 44 909 A1 shows an electrical connection unit with contact pins, which are elastically and electrically coupled by means of a spring to a printed circuit board. At the side facing away from the contact pins of the circuit board is soldered to a mating terminal for crimping a ribbon cable.
  • the US 4,494,092 shows a connector with multiple plug pins.
  • the plug contact pins store in a cylindrical housing. Transverse to the longitudinal extent of the cylindrical housing different disk-shaped elements are provided.
  • the plug contact pins have shoulders which each store in a recess in a rigid plastic disc. Adjacent to this plastic disc another rigid plastic disc is arranged to retain the plug contact pins in the axial direction.
  • this connector has filter elements in the form of disk capacitors.
  • a filter connector with shielding has a shielding metal housing.
  • a plurality of arranged in a small grid contact elements in the form of plug contact pins are provided.
  • the plug contact pins extend through a strip body and an insulating plate.
  • the insulating plate has a number of the contact elements corresponding number of metallized feedthroughs.
  • the metallized bushing merges into a contact element conductor at the top side of the insulating plate.

  • embossed spring plates are cut on the shield, which serve to fix the insulating plate.
  • the invention is therefore based on the object to provide a connector which has a long life and also allows an electrical interconnection, which has precise electrical properties.
  • the connector according to the invention comprises a plurality of plug contact pins, a housing in which the plug contact pins are arranged, and a circuit board, which is arranged in the housing and is electrically connected to at least one of the plug contact pins.

  • the plug contact pins are fixed without tilting in the housing by means of two spaced apart insulating body.
  • the board has discrete electrical components, e.g. Capacitors and / or coils and is mounted in the housing so that it is mechanically decoupled to the plug contact pins and / or to the housing, so that relative movements between the plug contact pins and the housing cause no tension on the board.
  • the plug contact pins By providing a board with discrete electronic components in the connector, it is possible to connect the plug contact pins with any electrical circuits.
  • the variety of circuits is limited solely by the limited area of the board.
  • the inductance is much more precise than the inductance of plugged on the plug pins ferrite.
  • the plug contact pins are mechanically fixed in the housing by means of the insulating body.
  • These insulators are usually made of injection molded plastic parts. These injection molded parts have mechanical tolerances, which are usually greater than the mechanical tolerances of the housing formed of metal. As a result, a game between the insulating bodies and the housing and thus between the plug contact pins and the housing can not always be completely avoided. Due to the inventive mechanical decoupling of the relative movements between the plug contact pins and the housing of the board this game causes no problems.
  • the mechanical decoupling of the board with respect to the plug contact pins and / or the housing can be effected by a resilient electrical connection between the board and the plug contact pins and / or the housing.

  • the hollow body formed by the two inner insulating bodies 4/5 and 4/6 has two narrow side surfaces 45 and two longitudinal side surfaces 46 (FIG. FIG. 9 ).
  • the upper longitudinal side surface has a shallow recess 47 (FIG. FIG. 9 ).
  • the board is a small piece with an edge portion. This edge portion is a part of the ground trace 44.
  • a Leitkissen 48 is arranged, which is a piece of foam, which is covered with an electrically conductive tissue.
  • the Leitkissen 48 touches with one side of the front edge of the circuit board of the board and is with its other side with the housing 2 in contact and thus establishes an electrical connection between the grounding track 44 and the housing 2 ago. In FIG. 9 the Leitkissen is partially cut away to make the recess 47 visible.
  • pockets 49 are again provided for receiving the electrical components 39, 43 of the board 5. These pockets 49 may be lined with an elastic material.
  • the board 5 is arranged with clearance between the two inner insulators 4/5 and 4/6, wherein it is acted upon on both sides by the sub-pins 32, 33 with little force due to the spring action of the sub-pins 32, 33 spring elements.
  • the insertion forces are introduced to the shoulders 16 of the sub-pins 32 in the inner Frontteilisolier emotions 4/5 and derived via the arranged in the corner spacers on the other inner remindteilisolier emotions 4/6 and on the adjacent thereto the outer remindisolier emotions 4/7 on the housing 2.
  • the insertion forces of the connector 1 are thus not transmitted to the circuit board 5.
  • the board 5 is thus encapsulated by the inner insulator of the external mechanical loads.
  • FIGS. 14a to 14d show by way of example some filter circuits that can be realized with the connectors according to the invention.
  • Ze denotes the input impedance and Za the output impedance. Between the input impedance Ze and the output impedance Za is the connector.
  • Figure 14a shows a C-filter, in each case a capacitor C is connected in parallel to a plug pin 3.
  • FIG. 14b shows an L-filter in which an inductance in series with the plug contact pin and a capacitance is arranged parallel to the plug contact pin.
  • the series-arranged inductance can be realized in a connector with continuous plug contact pins 3 by means of a ferrite body.
  • the inductance may also be formed by a coil.
  • the inductance of a coil is much more precise than that of a ferrite body, so that such a filter is much more precise than a filter formed with a ferrite body. This is a significant advantage, because in the design of the filter whose tolerances must be considered. If the tolerances are lower, the frequency band to be passed by the filter can be defined much narrower and less spurious frequencies can pass through the filter.
  • FIG. 14c shows a Pi filter.
  • the pi filter has an inductance L arranged in series with the plug contact pin and two capacitors C1 and C2 connected in parallel therewith.
  • the third embodiment has such a pi-filter, which consists of the coil 39 connected in series to the sub-pins 32, 33 and the corresponding capacitors 43.
  • such a pi filter can be realized in that two boards are provided in the connector, which have a capacitor for each plug pin and between the two boards a ferrite body is arranged, which forms the inductance.
  • a ferrite body is arranged, which forms the inductance.
  • such an embodiment can only be produced with large tolerances.
  • Figure 14d shows a T-filter with two series-connected coils and a capacitor connected in parallel to the plug pin.
  • the C-filter has an attenuation of about 20 dB
  • the L-filter has an attenuation of about 40 dB
  • the pi-filter and the T-filter each have an attenuation of about 60 dB. It can be seen from this that the attenuation of the filters is stronger, the more complex they are formed.
  • a board integrated in the connector it is basically possible to provide filters of any desired complexity.
  • several boards are provided in the connector in a stacked arrangement, so that there is sufficient space for the individual components.
  • the filters discussed above are passive filters.
  • an active filter in the connector.
  • a supply voltage is to be supplied via a plug contact pin of the filter circuit.
  • the filter then includes active elements, such as electrical amplifiers and control devices.
