Definitions

  • the invention relates to a housing for receiving a circuit board with a electrical connection zone and with an insulation displacement device according to claim 1.
  • Insulation displacement devices are, for example, in the prior art known from DE-4 343 444 and each have a base body arranged metal cutting to cut the insulation of the Head, after which the cutting simultaneously the head on the one hand Clamp and on the other hand establish an electrical connection.
  • DE 35 45 305 C2 is a terminal for connecting one or more Insulated conductor having ribbon cable known in the case of the housing the terminal is provided with metal contacts with cutting edges. The However, the clamp with its housing is mounted directly on the circuit board and fed the ribbon cable accordingly.
  • From DE 34 22 607 C2 an arrangement of several insulation displacement devices, for example from FIG for a ribbon cable and an associated one Holding clamp device that presses the ladder into the cutting edges and on the other hand locked the ladder.
  • US 5,492,485 shows, for example, in FIG. 16 a housing with a PCB connected to a contact pin at a connection zone, which passed through the housing into a socket and there with an outer connector is connected.
  • the outer connector has one Bending spring for contacting the contact pin, the bending spring for on the other hand connected to a conductor via an insulation displacement connection is.
  • This housing thus has an elaborate plug - socket - Connection on which the connector is first connected to the conductors must become.
  • the object of the invention is to show a housing which is the circuit board and their electronic components very reliably against external influences protects and at the same time is very easy to connect with electrical conductors. This object is solved by the features of claim 1.
  • the insulation displacement device By arranging the insulation displacement device outside the housing, there are no openings in the housing for inserting the electrical conductors more is required, through which outdoor air, moisture and other chemical substances penetrate and on the circuit board with their electronic components caused damage.
  • the insulation displacement device is therefore with its basic body on the surface of the The outside of the housing is mounted or inserted into it or injected with it, an electrically conductive contact pin on the base body
  • the inside of the housing is provided through the housing. While thus the conductors outside the housing by means of the insulation displacement connection be contacted, is the contact pin inside the housing connected to the circuit board.
  • the housing is made of plastic and the Contact pin is integrated into the housing during manufacture, especially when spraying the plastic mass from this is enclosed.
  • the circuit board in the electrical Connection zone an opening.
  • the contact pin is by means of an interference fit between the outer surface of the contact pin and the inner surface of the opening and / or locked by a solder connection and electrically connected.
  • solder connection By a press fit can also be achieved by soldering the contact pins to the Connection zones of the circuit board can be dispensed with, which in considerable Scope of manufacturing costs can be saved.
  • the insulated conductor is made using additional holding clamps without cutting locked without damaging the insulation.
  • the housing preferably has an indentation, in which the insulation displacement devices are arranged and the one Has stop to which the conductors can only be applied such that these then refer to the respectively assigned insulation displacement devices are aligned.
  • the indentation is preferably protected by a cover which is preferably identical to the holder-clamping device.
  • the cover can be locked onto the housing by means of a snap-in device.
  • Such a housing can particularly preferably be used to connect Printed circuit boards in protective housings use the particularly high insulation requirements be placed, in particular on watertightness or Pressure stability.
  • the single figure shows a housing 1 for receiving a circuit board 2 and an insulation displacement device 4 for electrically connecting an insulated Conductor 5 with a connection zone 3 on the circuit board.
  • the an insulation displacement device in detail shows, of which, however, a large number in parallel one behind the other arranged for contacting with a flat conductor cable are provided.
  • the housing 1 has the circuit board 2 and on the inside on the outside 1.2 an indentation 13 in which the insulation displacement device 4 is arranged.
  • the insulation displacement device 4 consists in this embodiment of two pairs of cutting edges 4.2 as well two pairs of holding clamps 4.1 without cutting, all of them together the base body 4.3 are arranged.
  • the base body 4.3 of the insulation displacement device 4 is with its underside on the surface of the Housing outside 1.2 arranged.
  • the outside of the housing 1.2 can Area of the base body 4.3 also a recess for the Have base body 4.3, so that this in the housing outside 1.2 can be lowered.
  • Other uses up to Injection of the base body 4.3 into the plastic material is also conceivable.
  • the contact pin 4.4 is preferably already in the manufacture of the Plastic housing injected with the plastic compound. Basically is however, a subsequent insertion of the contact pin 4.4 into the housing 1 possible. However, the tightness of the arrangement would be adversely affected.
  • a cover 6 is provided above the indentation 13, which means a plastic film hinge 7 is movably connected to the housing 1 and is locked by the latching means 9 and 10 on the housing 1.
  • the locking means 9 and 10 each have a hook on the cover 6 and one Snap on the outside of the housing 1.2.
  • the locking means 9 is used in particular to relieve the plastic film hinge 7. Also points the cover 6 support webs 8, which the conductor 5 in the terminals 4.1 and Press in cutting 4.2 and then prevent it from sliding off.
  • the leader 5 consists of an electrically conductive core 5.1 and insulation 5.2.
  • the conductor 5 is inserted into the opening 11 of the cover 6 introduced and then when closing the cover 6 in one operation at the same time by means of the support webs 8 in the cutting edges 4.2 and clamps 4.1 pressed in.
  • the cutting edges 4.2 as indicated in the figure, the insulation 5.2 of the conductor 5 so that it becomes an electrically conductive Connection between the electrically conductive core 5.1 of the conductor 5 via the metallic cutting edges 4.2, the base body 4.3 and the contact pin 4.4 of the Insulation displacement device 4 to the electrical connection zone 3 of the PCB is coming.
  • the symmetrical arrangement of the cutting edges 4.2 and terminals 4.1 with respect of the contact pin 4.4 is mechanically advantageous, but not mandatory required.
  • the terminals 4.1 serve to relieve the strain on the conductor 5.
