Each holder half (5, 6) has two rounded parts (1) having a semi-circular cross section. The rounded parts (1) of each holder half (5, 6) are connected by a flat intermediate part (2). A number of grooves (7) are formed on the outside of the rounded parts (1).

Description

CABLE HOLDER
Technical Field
The present invention concerns a junction box cable sealing. Expressed differently it is a cable holder, for a cable to be received in a junction box, cable cabinet etc.
Prior Art
The cable holder of the present invention may be used with cables for electricity, communication, computers etc. The cables may be any kind of cable including optical fibre cables.
Today it exists a large number of different devices to hold and seal cables received in a junction box, cable cabinet etc. Normally, the known devices are designed for only one dimension of the cable to be received. Thus, a number of such devices must be kept in stock if cables of different diameters are to be used.
A holder or sealing device for cables should protect against dust, moisture etc., at the same time as it should hold the cable in a secure way.
Summary of the Invention
One object of the present invention is to have a holder adaptable to cables of different diameters. Another object is to have a simple and, thus, inexpensive cable holder but that gives a reliable and tight seal. Thus, it should be simple both to produce and use and at the same time be reliable. A further object is that the holder should be held in place in the junction box without the use of any adhesive, weld or other fastening means. The form of the cable holder is adapted to the form of a junction box in which it is to be received. The expressions "upper", "lower" and corresponding expressions refer to the directions as shown in the drawings. A person skilled in the art realises that the holder in use may have any orientation. As used in this descrip- tion the expressions "axial", "radial" and similar expressions are in relation to a cable received inside the cable holder .
Even though the invention has been developed for cables received in junction boxes, a person skilled in the art realises that the same technique may be used in many circumstances, e.g. for wires, pipes in any type of transition through a wall or the like. For ease of description normally only the expressions "cable" and "junction box" are used in this description.
Brief Description of the Drawings
The invention will be described more closely below by way of an example and with reference to the enclosed drawings. In the drawings: Fig. 1 is a perspective view of a cable holder according to the present invention;
Fig. 2 is a side view of the holder of Fig. 1 ;
Fig. 3 is an end view of the holder of Figs. 1 and 2 ;
Fig. 4 is a perspective view of a part of the holder of the previous Figs.
Detailed Description of a Preferred Embodiment In the shown embodiment the holder has two rounded parts 1 and a cable, wire or pipe is to be received inside each rounded part 1. The holder is formed of two identical parts forming an upper half 5 and a lower half 6 of the holder .
The holder halves 5, 6 are normally moulded in a flexible or elastic material, preferably rubber, such as EPDM, or plastic. A person skilled in the art realises that any flexible material giving a tight seal and an appropriate holding effect on the cable may be used.
Each holder half 5, 6 has two rounded parts 1, which are semicircular in cross section. The two rounded parts 1 are connected by a flat intermediate part 2. On the outside of the rounded parts 1 outer flanges 4 are formed. The semicircular, rounded parts 1, the intermediate parts 2 and flanges 4 of each holder half 5, 6 are arranged so that when the holder halves 5, 6 are brought together with the rounded parts 1, intermediate parts 2 and flanges 4 of each holder half 5, 6 abutting each other, a holder is formed having two rounded parts 1 with circular cross section. In the formed holder the intermediate parts 2 and flanges 4 are placed in line at the middle of the holder. Peelable sheets 3 are arranged on the inside of the rounded parts 1. The peelable sheets 3 are adhered to each other strong enough to hold the sheets 3 together but weak or loose enough for the sheets 3 to be peeled off by hand. The sheets 3 are press fitted inside the rounded parts 1. By peeling off a suitable number of sheets the inner diameter of a rounded part 1 is adapted to the outer diameter of a cable, wire or pipe to be received in the rounded part 1. The number of sheets 3 peeled off should be such that the inner diameter of the opening formed inside a rounded part 1 should be slightly smaller than the outer diameter of the actual cable received inside said opening of the rounded part 1. Thereby, the elastic holder will be pressed against the cable when the junction box is assembled. If no cable is to be received in one of the rounded parts 1 of the holder a blind in the form of a round centre core is placed in that rounded part 1.
On the outside of the rounded parts 1 circular grooves 7 and ridges 8 are formed. In the shown embodiment there are four grooves 7. A person skilled in the art real- ises that the number of grooves 7 may vary, depending on the dimensions of the holder etc. The form and number of the grooves 7 of the holder as well as the form of the intermediate part 2 and the flanges 4 are adapted to the junction box in which the holder is to be received. Two parts of the junction box that are to be brought together have co-operating recesses to receive the holder halves 5, 6 forming the holder. The form of the recesses is adapted to the form of the holder. Thus, the recess of the junction box has a number of grooves to receive the grooves 7 of the holder.
The holder is kept in place by being squeezed between an upper part and lower part of the junction box, i.e. without the use of any adhesive or other means of attachment. A radial sealing pressure is accomplished when the upper and lower parts of the junction box are assembled, e.g. by means of screws or clamps. The dimensions of the grooves of the junction box and the grooves 7 of the holder are such that an axial sealing pressure is given. The axial sealing pressure could be given in that the width of the grooves of the junction box is somewhat smaller than the width of the grooves 7 of the holder. As an alternative or a combination the outer diameter of the grooves 7 of the holder may be slightly larger than the inner diameter of the grooves of the recess of the junction box, to give the axial sealing pressure.
In use one holder half 5, 6 is placed in a recess in each of two parts of a junction box or the like that is to be assembled. The appropriate number of sheets 3 for the actual cables are peeled off from the centre of the rounded parts 1 of each holder half 5, 6. The peeling off is made either before the holder halves 5, 6 are placed in the junction box or after the placement in the junction box. Then a separate cable is placed in each of the rounded parts 1 of one of the holder halves 5, 6. If only one cable is to be received a centre core is normally placed in the centre of the rounded part 1 not receiving a cable. Finally, the parts of the junction box are brought together, whereby also the holder halves 5, 6 are brought together, and then the parts of the junction box are drawn together by means of screws, clamps or the like. As the parts of the junction box are drawn together a sealing pressure is accomplished between the holder and the junction box and the holder is pressed against the cable or cables received.
