Definitions
- the invention relates to a cable connection element of the type specified in the preamble of claims 1 and 5.
- Such cable connection elements which are fixed or pluggable with electrical devices serve to releasably connect the electrical connection points of such a device to the individual wires of an electrical cable in an electrically conductive manner.
- a cable connector of this type is known from US-A-3 980 380.
- the main disadvantage of this is that the support body, which is provided with insulation displacement terminals, is equipped with recesses into which the cable cores of a multi-core electrical cable have to be inserted, which presupposes that they have to be brought into a corresponding geometric arrangement before being inserted.
- Another disadvantage is the fact that the pressing of the cable wires into the insulation displacement connectors for the purpose of contacting with the aid of spring clips through the jacket body requires considerable effort.
- the invention has for its object to take advantage of the basic advantages of an insulation displacement connection, especially in the case of connecting elements with multiple electrodes, in such a way that the time and effort required to establish the cable connection can be reduced to a minimum without impairing operational reliability.
- the pressing-in process can be designed by evenly exerting pressure on the cable ends to be pressed in so that even relatively thin stranded wires can be pressed into the insulation-piercing terminals without risk of kinking.
- the cylindrical cable connection element shown in Fig. 1 is formed from a screw-like support body 1 with a rectangular thread 2 and a sleeve-shaped union nut 3 made of insulating material with a corresponding internal thread for screwing onto the support body 1 and with the sealing and strain relief rings 4 made of elastic material arranged between the two.
- the union nut 3 has the shape of a sleeve open on one side and is dimensioned such that it completely covers the supporting body 1 in the cut state and axially projects beyond the insertion side by such an amount that a cavity for accommodating the rings 4 for cable strain relief and sealing is created.
- the closed end face of the union nut 3 facing away from the support body 1 is provided with a bead 5 which closes the union nut 3 except for an opening 6 for the passage of the cable 7 (FIG. 2).
- the support body 1 is fixedly connected to a device 8 at its end opposite the insertion side.
- the support body 1 has, from its insertion-side end face to the device-side end, axially extending, symmetrically arranged, outwardly open groove-shaped recesses 9, 10, 11, 12 with a rectangular cross section for receiving insulation displacement clamps 13, 14, 15, 16.
- These recesses are designed such that one of their walls is arranged in a plane of diameter and the opposite wall of the recess in question, which extends parallel to the former, is radially offset at a distance from the insulation displacement connector.
- the insulation displacement connectors 13, 14, 15, 16 electrically connected to the respective device connection are arranged, as shown in FIG. 3, in the recesses 9, 10, 11, 12 respectively assigned to them in such a way that their broad sides extending transversely to the clamping notch, in cross-sectional planes axially offset with respect to the thread pitch lying in the middle, between the entry-side end face and the device-side end of the support body 1 with its apex surface, protrude into the thread crest.
- the cable core located in the respective recess is first placed on the fanned-out outer edge of the cutting notch of the relevant insulation piercing terminal.
- the cable core thus laid is pressed into the cutting notch with the aid of the union nut 3.
- the thread as can be seen in FIG. 2, is designed in such a way that the effective thread height, which corresponds approximately to the maximum diameter of the cable core, at the end of the device, starting from the thread base, gradually increasing to the height of the thread comb during the first threads.
- the resulting force Pd must now point at least approximately in the direction of the cutting notch, so that the cable core cannot be sheared off on the front edge of the respective cutting terminal , but slides into the cutting notch.
- This is achieved in the simplest way in that the recesses and thus also the insulation displacement clamps are arranged radially offset with respect to the diameter axes with the cutting notches parallel to these but in the direction of rotation of the union nut by half the width of the recess.
- the seal 4 for strain relief of the cable 7 and for protection against the ingress of dust and moisture into the connecting element in the cable-side cavity of the union nut is screwed on the union nut 3 on the support body 1, as shown in FIG. 2, by the bead 5 the union nut 3 in the insertion area of the cable 7 against its surface and against the end face of the support body 1.
- the union nut 3 rests dust and moisture-tight on an O-ring 21 made of elastic material and inserted into a groove of the supporting body 1 on the device.
- the cable connection element according to the invention is designed as a cable sleeve for connecting two cable ends or as a T-piece for connecting two cables to one device.
- the corresponding cable connection element described above is also made of a screw-like support body 22 with the thread 23, which can be a normal metric thread, for example M14, and the sleeve-shaped cap nut 3 with a corresponding internal thread for screwing onto the support body 22 and with formed between the two pressure body 24 made of elastic material.
- the union nut 3 has the shape already described of a sleeve open on one side and is in turn dimensioned such that it completely covers the supporting body 22 in the screwed-on state and projects axially on the insertion side by an amount such that a cavity for accommodating the pressure body 24 instead of the rings 4 (Fig. 1) arises.
- the support body 22 is fixedly connected to the device 8 at its end opposite the insertion side.
- the support body 22 has from its insertion-side end face to the device-side end axially extending, symmetrically arranged, outwardly open groove-shaped recesses 25, 26, 27 with an approximately rectangular cross-section for receiving the insulation displacement clamps 28, 29, 30. These recesses are coaxially symmetrical in the support body 22 embedded.
- the insulation displacement connectors 28, 29, 30, which are electrically connected to the respective device connection, are arranged in the recesses 25, 26, 27 assigned to them in accordance with the illustration in FIG finally extend radially outwards in the middle between the entry-side end face and the device-side end of the support body 22 with the threaded foot.
- the pressure body 24 is annular so that its outer diameter approximately corresponds to the inner diameter of the union nut 3 and its inner diameter approximately corresponds to the outer diameter of the cable 7 to be inserted.
- the pressure body At its end facing away from the support body 22, the pressure body is feathered, so that after the union nut 3 has been screwed on, its inner wall, which tapers conically towards the cable entry side, can be compressed by such an amount that it presses the elastic ring 31 against the cable and relieves it of strain .
- the pressure body 24 Towards the support body, the pressure body 24 is provided with fingers 32, 33, 34 which are elastic in the radial direction and are of such a length that they are in the abutting state of the pressure body 24 on the end face of the support body 1 above the insulation displacement terminals 28, 29, 30, the ends the fingers 32, 33, 34 are shaped so that they can be pressed in elastically by a certain amount.
- the thread of the union nut 3 as shown in FIGS.
- the union nut 3 rests on the device side on the elastic 0-ring 36 embedded in the support body 22 and on the insertion side on the elastic 0-ring 37 inserted in the pressure body 24, so that the interior of the connecting element prevents the ingress of dust and moisture is protected.
- the special design of the pressure body 24 ensures that even very flexible cable cores are pressed perfectly into the clamping notches by its fingers 32, 33, 34, so that excellent electrical contacting can also be produced in this case.
