Cable coupling

FIELD OF THE INVENTION The invention relates to a cable sleeve for fastening cables, in particular telecommunication cables or extensions 5 of electrical wires, comprising two half-shells, each of which has at least one cable passage at each end of the sleeve, including seals fitted between the half shells placed in the grooves at the edges of the half-shells facing each other 10, and sealing rings of elastic raw material disposed in the cable passages.

The sleeve known from EP 531 276 A has external sealing rings at the end surfaces in the region of the cable penetration openings which are pressed by the cable entry supports against the thickened ends of the seals in the area of the end faces which are between the half shells of the known cable sleeves.

The cable sleeve known from EP 531 276 A has been satisfactorily solved externally by the use of sealing rings resting against the end faces of the cable sleeve. However, the manufacture of the seal requires extra care since the surfaces of the seals and especially the ends of the seals running in the longitudinal direction must not be contaminated. In addition, putting on tires is not always ____: it is not easy to hold on until; the cable entry brackets are screwed on.

The Y-seals known from CH 566 658 A or DE 20 50 536 A do provide a good seal, but the known seals from the above-mentioned publications are complicated to handle. Also, placing these seals in the half-shell of known cable glands:, · / · is not always simple.

::: US 3,796,823 A is known according to the preamble of independent claim 1 *. Cable coupling. In this cable sleeve, the sealing rings located in the penetrations are radially loaded so that they press in the region of the penetrations against the smooth ends of the ribbon-like seals between the half-shells.

It is an object of the invention to provide a cable gland which is simply made and easy to install.

According to the invention, this object is substantially achieved by providing the sealing heads in the region of the penetration openings with angled end faces aligned with the inner surface staggered from the inner end of the penetration openings, the sealing rings having a staggered outer contour, in the axial direction of the passage opening, and that one step of the stairs is located in the passage opening and the angular end faces of the seals and the other step in the portion projecting into the passage opening 15 of the press section.

Preferred embodiments of the cable sleeve according to the invention are claimed.

The seal according to the invention retains the advantages of EP 531 276 A, but simplifies the manufacture of the seal. There is also no risk of contamination of the ends of the seals as they are well protected from contamination by placing them inside the cable entry holes.

Other advantages of the invention will be apparent from the following description of an exemplary embodiment of a cable sleeve according to the invention, shown in the drawing, wherein: and its upper half shell is partially cut.

The cable sleeve of the invention, in the embodiment shown herein, »· · I« · ;;; In the 30 exemplary embodiments, it comprises a half shell 2 and a second half shell 3, which is primarily identical in design, and both half shell 2 and 3 are joined to one another by screws inserted through the holes 5 along their edges.

'·, · · In the exemplary embodiment shown, the cable sleeves 35 1 each have two cable > penetration openings 4, bounded together by half-shells 2 and 3.

. For sealing the cable sleeve 1, there are seals 10 and 11 which are inserted into the grooves in the narrow sides 6 and longitudinal sides 7 of the cable sleeve 1. In this embodiment, the seals 10 and the narrow sides are separated 6. In the region 6, the ends 13 of the seals 10 and 11 are free in the region of the cable sleeve penetration openings, whereby the ends 13 of the seals 10 and 11 are angled when viewed from above (in the viewing direction of the drawing). 4, complementing it so that the surfaces 14 are in alignment with the inner surface 15 10 of the passage openings.

It should be noted here that the cable sleeve, which in each case has only one passage opening 4 on the narrow sides, omits the seals 11 and thus has only two seals 10. Thus, for more than two passage openings 4 there are 15 This means that the invention is applicable to a cable sleeve having a different number of passage openings on the narrow sides 6 (for example, one passage opening 4 on the narrow side 6 and 20 two opening openings 4 on the other narrow side 6).

The gaskets 10 and 11 have a desired cross-sectional shape and may be rectangular, square, rectangular with rounded angles, elliptical or circular, but one can also consider the .Y: 25 cross-sectional shape proposed for EP-531 276 surrounded by star:, ·. cross-sectional shape.

A sealing ring 20, which is an elastic, deformable raw material, is inserted into the cable penetration opening 4 in each case: ;;;; 30 (eg rubber elastic plastic). The sealing ring 20 has a stepped outer contour and a step 22 facing the inner part of its cable sleeve 1 rests against the angled end faces 14 of the seals 10 and 11. In use, the outwardly facing step 21 of the sealing Y ring 20 engages the clamping member 25.

35, the clamping member 25 is provided with an external thread 26 which can be threaded into a corresponding internal thread 27 of the passage opening 4. The clamping portion 25 'is pressed against the surface 28 of the sealing ring 20 when it is screwed into the opening 4, its inner surface rests sealing against the pushed cable of the clamping member 25 and the sealing ring 20. The outer surface of the sealing ring 20 further rests against the inner surface 15 of the through hole 4 and against the end faces 14 5 of the ends 13 of the seals 10 and 11.

Both the sealing ring 20 and the clamping portion 25 may have at least a simple slot for ease of installation on the cable. In this case, the gap of the sealing ring 20 may be staggered as shown in the exemplary embodiment 10 so as to ensure secure sealing also in the area of the gap.

Opposite the slot 30 in the clamping member 25 may be a hinge (not shown) such that the clamping member 25 can be opened and closed. The enclosed space shown in the drawing can be secured by a ballast 31.

15 As an alternative to the coupling device 31, the clamping member 25 may be held in a closed position by means of screws. However, it is also conceivable to have an embodiment in which the clamping member 25 is divided into two halves of the ring and which are held together by two diametrically opposed screws 20 when the clamping member is mounted on the cable.

Another embodiment of the clamping member 25 may be contemplated having a smooth wall (without thread 26) which slides into the passage opening 4 (having no thread 27 on its inner surface 15). This type of clamping member 25 can be. : 25 presses sealing ring 20 towards cable sleeve 1 narrow ·; · Screws into the screw holes on page 6.

their outer surface rests sealing against the end faces of the seals 10, 11 and against the inner surface 15 of the through hole 4.

The invention may be summarized as follows:

The cable sleeve 15, consisting of two half-shells 2 and 3, is sealed in its circumferential region with seals 10, 11. The seals 10, 11 terminate in the area of the cable penetration openings 4 in the cable sleeve 1 which lead to a joint.

To seal the housing halves 2 and 3 against each other, they are joined with screws so that the seals 10 and 11 placed in the grooves seal the sleeve 1 over its peripheral area. Sealing holes 20 are provided in the passage openings 4, the outer surface of which is resting against the end surfaces 14 at the ends 13 of the seals 10, 11. The inner surface of the sealing ring 20 rests against the outer periphery of the cable 15 introduced. It further has clamping portions 25 to be screwed into the through holes 4 which elastically shape the sealing ring 20 so that its outer surface rests against the inner surface 15 of the through opening 4, including the end faces 14 of the seals 10, 11, and its inner surface clamps against the outer periphery.
