Description

Strain Relief Device at Joining Apparatus for Cables
Field of the invention
The invention relates to a strain relief device arranged at a joining apparatus, having a high tensile strength, for cables. More particularly the invention relates to a strain relief device of the kind as set forth in the preamble of claim 1. The invention relates also to a joining apparatus provided with strain relief devices according to claim 7.
Back ground of the invention
By SE 503 964 C2 a strain relief device provided at a joining apparatus for sea cables is known. Cables to be laid down in open sea, lakes or watercourses, will be exposed to various strong tensile forces at the time of laying down the cable, for instance, but also when an anchor by mistake is dropped into the cable. These forces may be in. the order of 400 kN. In the cable, the tensile forces are taken up by an external reinforcement sheath, which generally comprises a plurality of reinforcement wires having high tensile strength, and through the joining apparatus the tensile forces are transferred from the reinforcement wires of one cable to the reinforcement wires of the following cable. More particularly, the joining apparatus is provided at its ends with a cable connector which also functions as a strain relief device, to which the
reinforcement wires of respective end of the cable is attached in a way so as to provide high tensile strength. In the description below the cable connection will be named strain relief device. Depending on the size and field of application of the cable the diameter, the number and the material and hardness of reinforcement wires of the cable will be different. This means in principal that the joining apparatus, or at least the strain relief devices with associated clamping rings, must be adapted thereafter. Since these joining apparatuses and strain relief devices with associated clamping rings preferably are manufactured of stainless steel, which has high tensile strength and which is salt water resistant, this results in that they are expensive and difficult ,to manufacture, since it is difficult to machine this type of stainless steel.
To be able to minimize the number of joining
apparatuses/strain relief devices with associated clamping rings, and thereby the stock-keeping of the same, preferably one type of joining apparatus is used, although different strain relief devices may be used depending upon the diameter of the inner sheath and also depending on the reinforcement wires of the cable to be joined, which reinforcement wires can be formed in one, two or several layers and having different diameters. This in turn means that the clamping rings, which are used together with the strain relief devices for attaching the reinforcement wires of the cable to the joining apparatus, must be adapted to the diameter of the reinforcement wires etc., and more particularly to diameter of the conical holes of the clamping rings which are adapted to cooperate with the double conical surfaces of the strain relief device. This involves a problem since it is of outmost importance that clamping rings with correct diameter of the conical hole are chosen dependent upon the diameter of the reinforcement wires so that the anchorage/fastening of the same to the strain relief device is made correctly. With joining apparatuses of today a unique strain relief device with associated clamping ring kit is enclosed, the clamping ring kit being specific for each cable. This means that may types of joining apparatuses, or more particularly many types of joining apparatus kits must be kept in stock, which is expensive.
Summary of the invention
The object of the invention is to enable that the same clamping rings can be used at one and the same strain relief device for cables with reinforcement wires having different diameters and with at least one layer of reinforcement wires.
According to the invention this object is obtained by a strain relief device arranged at an joining apparatus, having high tensile strength, for cables, said cables comprise an internal sheath comprising a plurality of inner conductors/optical fibres adapted to be joined in the joining apparatus and surrounded by a reinforcement sheath consisting of
reinforcement wires having high tensile strength, said strain relief device comprises at one end, opposite to the joining apparatus, double conical surfaces having counter-directed conicity and least two clamping rings displaceable in the axial direction of the strain relief device, respective clamping ring having a hole with mirror-inverted conical surface which is essentially complimentary to the conical surfaces of the strain relief device, said clamping rings are adapted, when displaced towards each other, to clamp the reinforcement wires between the double conical surfaces formed between the strain relief device and respective mirror- inverted conical surface of respective clamping ring,
characterized in that the hole in respective clamping ring has double conical surfaces with counter directed conicity and the generix of which has different length.
Preferred embodiments of the invention are set forth in the dependent claims .

Description of preferred eir-bod irients
The expression cable in the description and claims below refers to, but not limited to, high voltage cables, communication cables , in particularly opto-cables, and similar.
With the expression generatrix in the description and claims below is meant the length of the surface of the hole of
5 respective clamping ring between which the reinforcement wires are actively attached and the strain relief device. In Fig. 5 respective generatrix of an external clamping ring 10 is denoted by LI and L2.
Fig. 1 illustrates a strain relief device 1 arranged at an 10 joining apparatus 2, having high tensile strength, for
communication cables, in particular opto-cables, which can be placed in open sea. Such cables comprise i.a. an inner sheath 4 comprising a plurality of internal optical fibres/
conductors adapted to be joined in the joining device. The i§ inner sheath is surrounded by a reinforcement sheath
comprising reinforcement wires 5 having high tensile strength. The strain relief device 1 has at an end opposite to the end fixed to the joining apparatus 2 double conical external surfaces Kl, K2 having counter-directed conicity and provided
:2D. with at least two clamping rings 10, 11 displaceable in the axial direction of the strain relief device, a hole in
respective clamping ring having together with an external conical surface of the strain relief device at least one essentially complementary, mirror-inverted conical surface.
25. The clamping rings 10, 11 are adapted to be pulled towards
each other by suitable means such as threaded bolts 12, for example, whereby the reinforcement wires 3 will be
fixed/clamped between the double conical surfaces of the strain relief device and respective conical surface of the
30 hole of respective clamping ring. As can be seen in greater detail in Fig. 2, the hole in the external clamping ring 10 has, according to the invention, as seen from the joining apparatus 2, double conical surfaces K3, K4, and the internal clamping ring 11 has double conical surfaces Κ3', K4' . These conical surfaces K3, K4, K3f , K4' have counter directed conicity and are mirror-inverted
relatively to the conical surfaces Kl, K2 of the strain relief device 1. The length of the generatrix of respective cone, which is formed in the hole of respective ring 11, 12, has however different length.
As well known, the strain relief device 1 has at a first end a suitable cable gland 20 having a cable gland nut 21 so as to form a sealing against the inner sheath 4 of the cable. As well known, the second end of the strain relief device has a suitable sealing device for sealing the strain relief device to the joining apparatus 2. Since the cable gland and the sealing device are known they will not be further described.
In the first embodiment, shown in Fig. 2, the external and internal clamping rings 10, 11 are shown directed towards each other in such away that the conical surfaces K3,K3', having the same length of the generatrixes, are facing each other, i.e. the bases of the cones with same length of generatrixes are facing each other. Thus, in this embodiment it is between the conical surface K3 of the clamping ring 10 and the conical surface Kl of the strain relief device 1 and between the conical surface K3' of the clamping ring 11 and the conical surface K2 of the strain relief device 1 that the
reinforcement res 5 are clamped.
As can be seen in Fig. 2, the cooperating conical surfaces Kl and K3, respective K2 and K3' are preferably parallel to each other, but this is not necessary. The conical surfaces K3, K4, K3' , K4' of the clamping rings 10, 11 respective the conical surfaces Kl, 2 of the strain relief device which will come into contact with the
reinforcement wires 5 have a suitable coarseness so as to increase the friction between the conical surfaces and the reinforcement wires.
At the passage between the double conical surfaces K3, K4, K3' , K4' of respective clamping rings 10, 11 there is a straight or curved portion 22, 22', as seen in Figs. 2-5.
Fig. 3 shows a second embodiment having a view similar to one shown in Fig. 2, however the internal clamping ring 11 is facing the external clamping ring 10 in such way that the conical surface K4' of the internal clamping ring 11 is facing the conical surface K3 of the external clamping ring 10. This results in that the play formed between the conical surfaces, which are parallel or essentially parallel to each other will be larger, which results in that a cable having larger diameter reinforcement wires 5 than the one used in the first embodiment can be joined by the same joining apparatus 2 with the same strain relief device 1. However, it should be noted that in this embodiment the dividing line between the clamping rings 10, 11 is slightly displaced to the left, as seen in relation to the meeting point between the conical surfaces Kl and K2 of the strain relief device 1.
Fig. 4 shows a third embodiment in a view similar to the one shown in Fig. 2 and 3, however, both the internal clamping ring 11 and the external clamping ring 10 are facing each other in such a way that the conical surface K4' of the internal clamping ring 11 is facing the conical surface K4 of the external clamping ring 10. This results in that the play formed between the conical surfaces which are parallel or essentially parallel to each other, will be larger compared to the play shown in Figs. 2 and 3, which results in that a cable having reinforcement wires 5 with a diameter even larger than the one in the first and second embodiments can be joined by the same joining apparatus 2 with the same strain relief device 1.
In the above embodiments a cone angle a, as defined in Fig. 5, between respective conical surfaces, which are parallel or essentially parallel to each other and is principally the same, and a centre axis of the strain relief device is between 4 to 12 degrees, preferably about 8 degrees.
In a further embodiment, not shown, it is possible to place one or several shims/washers between the surfaces of the clamping rings 10, 11 facing each other so as to obtain an even larger play between the conical surfaces which are
parallel to each other. These shims can be formed either as only one large shim having the same diameter as the clamping rings 10, 11 and provided with holes for the bolts 12, or as a . discreet shim placed around each bolt 12.
Fig. 6 is a perspective view of the joining apparatus 2, having high tensile strength, for cables shown without
protecting housing and provided with a strain relief device according to the invention at respective end.
From the above stated it can thus be inferred that it is possible by a strain relief device having at least two
clamping rings according to the invention to attach the ends of cables having different Lhickness of Lhe reinforcement wires. This results in that the number of joining apparatus having different dimension of the strain relief device and/or the clamping rings of the strain relief devices can be 3 reduced, and therefore the stock-keeping of said joining apparatus and said strain relief devices with suitable clamping rings can be simplified.
