Definitions

  • the invention relates to a device for holding cables, lines, hoses or the like with a hollow cylindrical mounting piece for the passage of the cable or the like and with a pressure screw which can be screwed onto the mounting piece and has an arched inner surface, the pressure screw on the mounting piece Clamping tongues are arranged on the facing side, and an elastic seal is arranged within the clamping tongues, and the clamping tongues lying on the curved inner surface of the pressure screw can be pressed together by screwing the pressure screw onto the assembly connection piece, and thereby the seal on the cable or the ⁇ same can be pressed.
  • the inner surface of the pressure screw is conical or spherical, that is to say circularly curved in a radial cross-sectional view, so that the clamping tongues are evenly pressed together when the pressure screw is screwed onto the assembly connection piece.
  • the conically or spherically curved inner surface of the pressure screw is provided with a grooving, toothing or the like, which comes into engagement with the clamping tongues and acts as a rotation lock for the pressure screw. Due to the conical-spherical design of the pressure screw inner surface and the associated uniform Compression of the clamping tongues may mean that the pressure to be exerted on the cable does not reach the height required to prevent rotation.
  • the object is achieved in that the inner surface of the pressure screw is oval in a radial cross-sectional view and as a result the clamping tongues can be pressed together unevenly.
  • Figure 1 is a front view of a Montagestut ⁇ zens
  • FIG. 2 shows a partially sectioned side view of the assembly socket from FIG. 1;
  • FIG. 3 shows a front view of a pressure screw
  • FIG. 4 shows a partially sectioned side view of the pressure screw in the direction of arrow A from FIG. 3; 5 shows a partially sectioned side view of the pressure screw in the direction of arrow B from FIG. 3 and
  • FIGS. 1 to 5 shows a sectional view of the assembled parts from FIGS. 1 to 5.
  • a hollow cylindrical mounting stub 1 shown in FIGS. 1 and 2 consists of tough elastic plastic, in particular polyamide.
  • the socket 1 has on its left side in FIG. 2 an outer connecting thread 2 and one for mounting on the wall . 14 of a housing or the like (see FIG. 6) required pressure collar 3 in the form of a hexagon.
  • An external thread 4 adjoins the collar 3 for applying a pressure screw 9 (FIGS. 3, 4 and 5).
  • a plurality of clamping tongues 6 are integrally and coaxially formed on the mounting piece 1, which extend up to the external thread 4 and are separated from one another by obliquely running slots 5.
  • the clamping tongues 6 and the slots 5 follow one another alternately and together form a tension collar 7, into which a hollow cylindrical seal 8 made of elastic material is inserted coaxially.
  • the mounting socket 1 has an undercut at the attachment point of the terminals 6, in which the seal 8 engages in a form-fitting manner. As a result, and through the clamping tongues 6, the seal 8 is held captive.
  • the cap nut-shaped pressure screw 9 shown in FIGS. 3 and 4 comprises an attack by a wrench Serving hexagon 10 and an internal thread 11, with which the pressure screw 9 can be screwed onto the external thread 4 of the mounting piece 1.
  • the inner surface 15 of the pressure screw 9 facing away from the Secbiskant 10 is curved or frustoconical and cooperates with the free ends of the clamping tongues 6, as will be described in the following.
  • FIG. 6 shows the hollow-cylindrical assembly connector 1 as it is fastened to the wall 14 of a housing by means of the connecting thread 2, wherein it is supported on the wall with the pressure collar 3 and is secured with a lock nut 17.
  • this socket 1 and the screw 9 are connected to one another in such a way that the clamping tongues 6 are supported on the inclined or curved inner surface 15 of the pressure screw 9 forming a support bearing and when screwing on the pressure screw 9, gradually move it in a fan shape towards the central axis of the cable gland.
  • the inner surface 15 of the pressure screw 9 is not spherical (spherical), but rather is curved in a cross-sectional view that deviates from the circular shape, in particular oval or elliptical, with the expression “curvature” also a frustoconical formation of the inner surface 15 should fall.
  • the oval 18 deviating from the circular shape can be clearly seen in FIG. 3. This oval shape means that in FIG. 4 the wall thickness of the pressure screw 9 increases in the area of the inner surface 15 than in Figure 5.
  • the oval curvature of the inner surface 15 leads to the fact that when the pressure screw 9 is screwed onto the mounting piece 1, the clamping tongues move unevenly towards the central axis of the cable screw and the cable 16 is consequently compressed unevenly (via the seal 8).
  • the clamping tongues 6 are pressed together more than in the area of the long axis of the oval 18 (FIG. 5).
  • the stronger compression of the clamping tongues 6 in the region of the short axis of the oval 18 achieves a fixation of the cable 16 in the cable gland, which is considerably stronger than in the case of a radial cross-sectional view of the spherical curvature of the inner surface 15.
  • the clamping tongues 6 are alternately bent more or less towards the central axis of the cable screw connection.
  • the clamping tongues which are bent more inwards, exert a greater frictional pressure on the inner surface 15. It has been found that this increased frictional pressure of the clamping tongues 6 on the inner surface 15 (in the region of the short axis of the oval 18) ensures, as a rule, that the pressure screw 9 on the fitting 1 is sufficiently secured against rotation, even if this curved inner surface is smooth.
  • the effect of the anti-rotation device can be increased even further if a grooving or toothing 13 (FIG. 3) is provided on the inner surface 15, which can come into positive engagement with the ends of the clamping tongues 6.
  • a grooving or toothing 13 FIG. 3
  • the clamping tongues 6 are separated from one another by relatively wide slots 5 which run obliquely to the radial direction. Instead of these slots, notches or narrow cuts could also be provided, as a result of which the clamping tongues 6 would slide over one another earlier when the pressure screw 9 was applied than in the embodiment shown in FIGS. 1 and 2.
  • the ends of the clamping tongues 6 forming the clamping collar 7 could also have a frustoconical contour in another embodiment of the invention. As can be seen from FIG. 6, the ends of the clamping tongues 6 can also engage directly on the cable 16.
  • the pressure screw 9 could alternatively also be designed as a non-screwable pressure part, which can be clamped together with the assembly connection 1, for example, like a bayonet lock or the like. This does not change the effect of the device described.
  • the main advantages achieved by the invention are that, on the one hand, because of the uneven compression of the clamping tongues 6 due to the oval inner curvature of the pressure screw 9, the cable is partially fixed, and on the other hand, the oval-curved inner surface 15 of the pressure screw is simultaneously secured against rotation delivers that works regardless of fatigue of the clamping tongues 6.

Abstract

Un dispositif de retenue de câbles, conduits, tuyaux ou similaires comprend une tubulure cylindrique creuse de montage, traversée par le câble ou similaire, et une vis de serrage (9) vissable sur la tubulure de montage et pourvue d'une surface intérieure courbe (15). Des languettes de serrage (6) sont agencées sur le côté de la tubulure de montage qui fait face à la vis de serrage. Une rondelle élastique d'étanchéité (8) est insérée dans les languettes de serrage. Lorsque l'on visse la vis de serrage sur la tubulure de montage, les languettes de serrage (6) qui s'appuient sur la surface intérieure courbe (15) de la vis de serrage (9) sont comprimées, sollicitant la rondelle d'étanchéité contre le câble (16) ou similiare. La surface intérieure (15) de la vis de serrage (9) a une section transversale radiale ovale (18), de façon à comprimer de manière irrégulière les languettes de serrage (6), ce qui permet d'obtenir une plus forte fixation du câble dans le dispositif et d'empêcher en même temps la vis de serrage de tourner.
