Abstract
A cable closure comprises first and second parts 10,20 arranged to fit together about a cable joint. The two parts 10,20 form a main enclosure for receiving the cable joint and a chamber 18, 19 adjacent each end of the closure. The main enclosure contains a sealant composition E which is expelled into the chambers 18, 19 upon fitting the two parts of the closure together around the cable joint. In applying a cable closure around a cable joint, the sealant composition provides a seal against the environment. Any excess composition is expelled into the chambers 18, 19, thereby avoiding contamination of the operator's hands.
Description
2358293 Cable closure The present invention relates to a cable closure,
particularly for telecommunications cables (including coaxial cables, wire cables and optical fibre cables).
In applying a cable closure around a cable joint, it is 5 a requirement to seal the closure against the environment. Often a gel or other sealing composition is used to provide an effective seal, but generally excess composition is expelled and contaminates the operator's hands.
We have now devised a cable closure which alleviates the problem outlined above.
In accordance with the present invention, there is provided a cable closure which comprises first and second parts arranged to fit together about a cable joint, the two parts being arranged to form a main enclosure for receiving the cable joint and a chamber adjacent at least one end of the closure, and at least one part of the closure containing a sealant composition which is expelled from the main enclosure, upon fitting the two parts of the closure together around the cable joint, to flow into said chamber.
Preferably each part of the closure is formed, at the or each end, with an end wall and, inwardly therefrom, with a partition wall, to define the end chamber which is to receive sealant composition as the two parts of the closure are fitted together. The end wall and partition wall are formed with recesses to accommodate the cable or bundle of cables extending through the end of the closure. As the two parts of the closure are closed together, the excess composition is forced out through the or each end of the main enclosure and into the respective end chamber.
Preferably the two parts of the closure are arranged to prevent the sealant composition being expelled through the sides of the closure. Preferably one part of the closure is 2 arranged to fit between opposed side walls of the other l4rt, preferably as a sliding fit.
Preferably the two parts of the closure are arranged t snap-engage together.
Preferably the cable closure is generally rectanc:4i-a in cross-section.
An embodiment of the present invention will no.w. b described by way of example only and with reference tc [i,th accompanying drawings, in which:
FIGURE 1 is a schematic isometric view of a c.
abl si closure of plastics material in accordance with the prc-4.en invention; FIGURE 2 is a view of the jointed cables pri(--)r: t application of the closure of Figure 1; i i i 1 FIGURE 3 is a view of a portion of one of the bundl,:4, 0 jointed cables; FIGURE 4 is a view of the top of the cover part of:
closure; FIGURE 5 is a side view of the cover part of lthe closure; FIGURE 6 is an underside view of the cover part c)fi th closure; FIGURE 7 is a plan view of the base part of th closure; FIGURE 8 is a side view of the base part ol: th closure; FIGURE 9 is an underside view of the base part of closure; FIGURE 10 is a cross-section through the base pa r 0 the closure; and FIGURE 11 is a longitudinal sectional view through!Ith cover and base parts of the closure.
Referring to Figures 1 and 2 of the drawings, a clei,Jur 3 comprising a cover part 10 and a base part 20 is applied to enclose a joint between two bundles of cables A,B. The cover part 10 and base part 20 are pre-filled with an encapsulating composition and are applied from opposite sides of the run of cables, to interfit together: as the two parts of the closure are brought together, the encapsulating composition is forced or extruded out of the opposite ends of a main enclosure section of the closure (as indicated by the arrows in Figure 2) to flow into respective end chambers and surround the cable bundles over zones a, b. As shown in Figure 3, each bundle of cables is held together by a cable tie T in the zone in question, which is upstream of the ends of the cut-back sheaths of the cables.
Referring to Figures 4 to 6, the cover part 10 of the closure comprises a generally rectangular- section trough having a generally flat top wall 11, two depending side walls 12,13 and depending end walls 14, 15. Inwardly of the end walls 14, 15, the cover part is formed with transverse partition walls 16, 17 to form chambers 18, 19 adjacent the opposite ends of the cover part. The end walls, 14,15 and partition walls 16, 17 are formed with arcuate recesses R1, extending from their lower edges to accommodate the cables.
Referring to Figures 7 to 9 of the drawings, the base part 20 of the closure comprises a generally rectangular section trough having a generally flat bottom wall 21, upstanding side walls 22,23 and upstanding end walls 24, 25.
Inwardly of the end walls 24,25 the base part is formed with transverse partition walls 26,27 to form chambers 28,29 adjacent the opposite ends of the base part. The end walls 24,25 and the partition walls 26,27 are formed with arcuate recesses R2, extending from their upper edges, to accommodate the cables.
It will be noted that the upstanding side walls 22,23 4 of the base part 20 are of a greater height, over the n ai section between the two partition walls, than over the sec,t;jons between the partition walls and respective end walls. In fitting the two parts of the closure together, the cover part fits between the upper portions of the side walls 22,23 c)', the base part, these upper portions of the side walls 22, 23 c)j' the base part engaging into complementary-shaped recesses e.c., 3 in the outer surfaces of the side walls 12 13 of the 1; c ver part 10. When the two parts of the closure are fully en.cfEgei together, the lower edges of the end walls 14,15 and partiition walls 16, 17 of the cover part seat onto the upper edges of th corresponding end walls 24,25 and partition walls 26,27 of' th base part: also, the lower edges of the side walls 12, 13 c)Jl:th cover part, between the end walls 14,15 and respec!tiv partition walls 16,17 seat onto the upper edges of. th corresponding sections of the side walls 22,23 of the tas part. The top edges of the side walls 22,23 of the basepar are formed with in-turned lugs e.g. 22a, 23a (see Figure 10): f o: engagement into recesses 12a,13a in the opposite sides of lth( cover part 10, such that the two parts of the closure ap engage together.
It will be noted that the top wall of the cover,pri and the bottom wall of the base part are formed, adjacent t:
ends, with slots S through which cable ties may be threadc-i,',, to retain the cables, and with holes H for use in mounting ei;thei part onto a wall or panel etc. One part of the closure is he,lci in position relative to the cable joint, using cable 't ie, passed around the cable bundles and through the correspon.d'LnSf slots S, before the other part of the closure is applied.
: 11 1 i the embodiment shown, the base part 20 is formed with tangsi ?0 a for engagement by the joint connector, to position the joint.
centrally.
Referring to Figure 11, the section of each part of h closure, between its partition walls, is pre-filled with a quantity E of an encapsulating composition such as a gel: each part is filled with this composition generally to a level of its end walls. A blank e.g. 30 is inserted into the recess of each partition wall, the edge of the blank engaging into a groove G in the edge of the respective recess, to contain the composition within the section between the two partition walls. The blanks are removed before the two parts of the closure are fitted together about the cable joint.
In fitting the two parts of the closure together about the cable joint, the composition will be expelled from the central, main enclosure section of the closure via the partition walls and into the end chambers: the composition is prevented from being expelled sideways by the upstanding side is walls of the base part. The composition accordingly fills the main enclosure between the two partition walls avoiding the presence of voids around the joint, and sealing the ends of the main enclosure. Preferably the end chambers become filled with sealant composition, so completely surround and encapsulating the cable bundles over the corresponding zones a,b with little or no composition exuding through the extreme ends of the closure.
