Definitions

  • the present invention relates to an insulation displacement device with a terminal housing and an insulation displacement terminal which is arranged in the terminal housing and can be actuated by means of an actuating element and by means of which a non-stripped conductor can be clamped.
  • Such an insulation displacement device is, for. B. known from DE 197 32 182 Cl.
  • the insulation piercing z. B compressible via levers that are pivoted. This requires both a comparatively large actuation space and comparatively high actuation forces. Furthermore, with the insulation displacement devices of the prior art, as a rule only a single conductor can be clamped. If several conductors are to be clamped, several insulation displacement devices connected to one another are required.
  • the object of the present invention is to provide a compact insulation displacement device which can be actuated with little force and by means of which several conductors can nevertheless be clamped.
  • the actuating element is designed as a screw and that by means of the screw additionally or alternatively, at least one further conductor can be clamped.
  • both conductors can be clamped without being cut to length and stripped.
  • the insulation displacement device according to the invention is particularly flexible.
  • the stripping of the stripped conductor is particularly reliable. This is especially true when the roof window is V-shaped. If the counter bearing is arranged between the screw head and the insulation displacement terminal, a particularly compact construction results.
  • the insulation displacement device is particularly simple in construction.
  • the screw has a screw neck with a screw neck thickness and the connecting web width is approximately equal to the screw head thickness, there is no restriction with regard to the conductor cross sections of the conductors inserted or insertable into the screw terminal due to the connecting web.
  • the screw can alternatively be axially displaceable or - at least essentially - axially non-displaceably mounted in the terminal housing.
  • the insulation displacement device When the screw is axially immovable, the insulation displacement device has an axially displaceably mounted frame body in the terminal housing, into which the screw can be screwed.
  • the insulation displacement clamp is actuated in this case by means of an actuating element which engages axially immovably in a recess in the frame body and is rigidly connected to the insulation displacement clamp, preferably in one piece.
  • FIG. 1 shows an insulation displacement device in section from the front
  • FIG. 2 shows the insulation displacement device of FIG. 1 from the side
  • FIG. 3 shows another insulation displacement device from the front
  • 4 shows the insulation displacement device of FIG. 3 from the side
  • FIG. 5 shows the insulation displacement device of FIG. 3 from above.
  • an insulation displacement device has a terminal housing 1.
  • a screw 2 is arranged in the terminal housing 1 and can be screwed into a counter bearing 3.
  • the counter bearing 3 is fixed to the housing according to FIGS. 1 and 2.
  • the screw 2 has a screw head 4 and a screw neck 5.
  • the screw neck 5 has a screw neck thickness d.
  • the screw head 4 and the counter bearing 3 define a screw terminal space 6 in which up to two stripped individual conductors 7, 8, z. B. stripped cable wires 7, 8, can be clamped.
  • the clamping takes place via a V-shaped roof washer 9, which is arranged between the stripped conductors 7, 8 and the screw head 4.
  • An insulation displacement space 10 with an insulation displacement clamp 11 is arranged in the terminal housing 1 below the counter bearing 3.
  • the insulation displacement terminal 11 can also be actuated by means of the screw 2.
  • the screw 2 interacts with the insulation displacement terminal 11 via a connecting web 12.
  • the connecting web 12 has a connecting web width b.
  • the connecting web width b is approximately equal to the screw head thickness d.
  • the permissible cross sections of the stripped conductors 7, 8 are thus - as in the case of a conventional screw terminal - determined by the dimensions of the terminal housing 1 and the screw head thickness d, but not restricted by the connecting web width b.
  • An insulation-stripped individual conductor 13 can be clamped and thus also contacted by means of the insulation displacement terminal 11, as the word “insulation displacement terminal” means.
  • the clamping of the non-stripped conductor 13 can additionally or alternatively to the clamping of the stripped conductor 7 or 8 or the stripped conductor managerial ter 7 and 8 take place. It is therefore optionally possible to clamp one, two or all three of the conductors 7, 8, 13.
  • the screw 2 is axially displaceably mounted in the terminal housing 1.
  • it can also, as shown in FIGS. 3 and 4, be axially immovable, at least essentially.
  • the terminal housing 1 has bearing points 14, 15 which suppress the axial displacement of the screw 2.
  • insulation displacement device has a frame body 16 into which the screw 2 can be screwed.
  • the frame body 16 is axially displaceably mounted in the terminal housing 1. When moving the frame body 16, it presses the stripped conductors 7, 8 against a contact tongue 17 and thus clamps it.
  • the frame body 16 also has a recess 18.
  • the recess 18 is widened - at least slightly - in its lower region.
  • An actuating element 19 engages in the recess 18, which is thereby axially immovably mounted in the recess 18.
  • the actuating element 19 is in one piece and thus in particular rigidly connected to the insulation displacement terminal 11. Together with the displacement of the frame body 16, the insulation displacement terminal 11 is thus also actuated. In the embodiment according to FIGS. 3 and 4 - see also FIG. 5 - this is designed as a pipe contact.
  • the insulation displacement device according to FIGS. 3 to 5 essentially corresponds to the insulation displacement device according to FIGS. 1 and 2. It only has, in addition to the screw terminal space 6 and the insulation displacement space 10, a further insulation displacement space 10 'in which a further insulation displacement terminal 11' is arranged. By means of the further insulation displacement terminal 11 ', a further non-stripped individual conductor 13' can be clamped and thus also contacted. By means of the insulation displacement Direction according to Figures 3 and 4, up to four individual conductors 7, 8, 13 and 13 'can be clamped in any combination.
  • the insulation displacement device according to the invention has a number of advantages.
  • a large cross-sectional area of the conductors 7, 8 can be covered by the screw-type clamp connection.
  • up to three or four conductors 7, 8, 13, 13 ' can be clamped.
