Definitions

  • the invention relates to an electrical insulation displacement tone clock element made of a stamped sheet metal part and a plastic connector housing equipped with the insulation displacement contact elements.
  • the known insulation displacement contact element essentially has a plug contact area with relatively easily bendable spring arms for mating plug contact elements and a insulation displacement contact area for receiving an electrical conductor wire and for contacting the metallic wire core of the conductor wire provided with an insulation sleeve.
  • the insulation displacement area has two insulation displacement jaws which are arranged at a distance and parallel to one another and are angled at right angles from a base plate.
  • An insulation displacement slot is made in each of the insulation displacement jaws, which opens opposite to the plug contact area and into which an electrical conductor wire can be squeezed at right angles to the longitudinal axis of the conductor wire, the edges of the slot cutting through the insulation of the conductor wire and making electrical contact with the metallic wire core.
  • the insulation displacement contact elements are placed in the chambers of a connector housing. The housing is designed so that the insulation displacement slots a insulation displacement contact elements seated in a housing chamber are open to the outside, so that the conductor wires can be pressed into the insulation displacement slots with a separate mounting device.
  • the known insulation displacement contact element also has a latching tongue which interacts with a latching edge in the housing chamber in a manner known per se. It is also provided that the free end edges of the insulation displacement jaws are bent at right angles to one another, so that retaining webs are formed which find corresponding counter-bearing surfaces in the respective housing chamber.
  • a disadvantage of this prior art is in particular that the conductor wire must be pressed into the insulation displacement slots and then a clamping bracket or a wire hold-down device must be bent over the conductor wire, the clamping bracket not being able to ensure adequate position fixation.
  • the object of the invention is to provide a very rigid insulation displacement contact element which can be inserted into the chamber of a connector housing, the insulation displacement contact being made when inserted and no additional steps required for fixing the position being required during assembly.
  • the insulation displacement contact element 1 which is essentially rectangular in cross section, consists approximately half of the plug contact area 2 and the insulation displacement area 3.
  • the insulation displacement region 3 has a rectangular insulation displacement jaw base plate 4, from the longitudinal side edges 6 of which an insulation displacement jaw 7 is bent at right angles, which is preferably the same Length as the base plate 4.
  • a contact spring arm base plate 10 of the same length is connected to the transverse edge 5 of the insulation-piercing jaw base plate 4 facing away from the plug-in contact area and is, for example, about half or more wider than the insulation-displacement jaw base plate 4 and which is struck by 180 ° on the insulation-displacement jaw base plate 4, expediently a short clamping tab 11 is connected to the transverse edge of the contact spring arm base plate 10 facing the plug contact area 2, which is pressed by rolling against the corresponding transverse edge of the insulation displacement jaw base plate 4 and is resiliently supported there, so that the double fold, consisting of the two base plates 4 and 10, is fixed pressed together.
  • the contact spring arm base plate 10 preferably has, starting at the transverse edge connected to the connecting web 9 and extending to approximately half its length, a longitudinal edge on which a row of teeth 13 with laterally projecting barb-like teeth 12 is arranged, the function of which is explained below.
  • a support jaw 14 is connected to the other half of the longitudinal edge of the contact spring arm base plate 10 and bent at right angles, so that the support jaw 14 extends parallel to and at a distance from the associated insulation displacement jaw 7.
  • the support jaw is somewhat wider than the insulation displacement jaw 7, the free longitudinal edge of the support jaw 14 being equipped with a further row of teeth 16 having barb-like teeth 15.
  • the function of the teeth 15 is also explained below.
  • the special arrangement of the support jaw 14 results in the transverse edge 19 of the support jaw 14 facing the row of teeth 13 practically forming the slot base of the insulation displacement slot 8 because the slot 8 is longer than the row of teeth 13 is long.
  • a spring arm 20 which is rectangular in cross section, is arranged in one piece with a support jaw web 21 and a base plate web 22, which are arranged at right angles to one another.
  • a short arcuate contact web 23 is bent at right angles, which extends approximately parallel to the support jaw web 21.
  • the two arcuate contact webs 23 of the spring arms 20 form the contact points for a mating contact (not shown). Due to its special spatial shape, each spring arm 20 is relatively rigid, but ensures a good spring characteristic.
  • the insulation displacement contact element 1 according to the invention can be plugged into a housing 24 which, as shown, is preferably equipped with an angular shape with a chamber body 25 and a conductor wire bearing body 26.
  • a chamber 27 with a rectangular cross section in the chamber body 25 for receiving an insulation displacement contact element 1 corresponds in size to the insulation displacement contact element 1. It has an insertion opening 28 and a bottom 29 opposite it. On the bottom 29 there are arranged in a row in the direction of the bearing body 26 conductor wire support blocks 30, 31, 32, a slot 33 being provided between the blocks 30 and 31 and a slot 34 being provided between the blocks 31 and 32.
  • the surface 40 of the lugs 30, 31, 32 is preferably in the form of a trough profile (in the form of a concave arc in cross section) and is adapted to the radius of curvature of a conductor wire 35 which is intended to lie on the lugs.
  • a cylindrical conductor wire insertion channel 36 is introduced into the conductor wire bearing body 26 per chamber 27 in the direction of the chamber body 25, each of which opens into a chamber 27 in the area of the lugs 32, the groove of the row of lugs being aligned with the bottom of the associated channel 36.
  • the invention shows that the insulation displacement device functions differently than in the prior art and can be ensured in a simple manner.
  • a conductor wire 35 is pushed from the channel opening 37 through a channel 36 into the chamber 27 until its end region rests on the blocks 30, 31, 32. Then an insulation displacement contact element 1 with the insulation displacement area 3 is inserted through the insertion opening 28 into the chamber 27 until the front end areas of the jaws 7 protrude into the slots 33 and 34 between the lugs.
  • the cutting edges of the jaws 7 delimiting the insulation displacement slots 8 have cut through the insulation 38 of the conductor wire 35 and contact the conductor wire core 39 (Fig. 2, right side).
  • the teeth 15 and — if present — the teeth 12 also get caught in the corresponding wall of the chamber 27.
  • the conductor wire 35 is thereby placed on the lugs 30 with the edge 19 of the support jaws 14, 31, 32 pressed (see Fig. 4).
  • the teeth 15 and 12 interlock so firmly in the wall material of the chamber housing that the contacted conductor wire end is held immovably.
  • the support jaws 14 also ensure strain relief because they can be supported against the corresponding chamber wall (see FIG. 4).
  • the jamming of the conductor wire 35 is so strong that even shortly before the lug 32, the conductor wire 35a can be bent out of the housing 24 or the conductor wire bearing body 26 at a right angle (see FIG. 4, dash-dot line wire 35a).
  • the chambers 27 of the housing 24 can be equipped with insulation displacement contact elements 1 with a pre-locking position (see FIGS. 3 and 2, left side), the insulation displacement area 3 being located just above the channel mouth 41 and only the end regions of the spring arms 20 protrude from the housing, the insulation displacement contact element 1 being held in this position by the clawing of the teeth 15 and 12 in the corresponding side wall of a housing chamber.
  • the conductor wires 35 can then be inserted freely into the housing thus equipped; Thereafter, the insulation displacement contact elements 1 can be depressed individually or together to produce the insulation displacement contact.
  • the insulation displacement contact according to the invention is electrically safer than the known Kon cycles of this type due to the special anchoring of the insulation displacement contact element 1 in a chamber 27 caused by the teeth 15 and 12. It should be emphasized that the assembly is extremely simple and that it is within the scope of the invention, the teeth 12 and / or 15 omit and only provide protruding longitudinal edges that cut into the wall of the chamber and thereby ensure a sufficient tight fit, either by hooking their corners. Instead of a row of teeth, a single tooth can also suffice.
