Abstract
A telecom cable cold shrinkage interconnection sleeve is provided, which belongs to a airtight sealing device for the interconnection protection of cable, which is characterized in that: a interconnection section bushed to a telecom cable (1) is arranged in tube shape and is composed of a section A and a section B; the shell of each branch tube is arranged as a cold shrinkage sleeve (2) made of elastic material; the cold shrinkage sleeve (2) realizes pre-expansion via a built-in helical plastic support tube (4); the helical plastic support tube (4) is made by coiling a self-buckling support reglet (5). During installation, pull out the helical plastic support tube, the cold shrinkage sleeve shrinks due to its own elasticity and wraps on the cable, so as to complete the wrapping and sealing for the interconnection section of cable. Therefore, the utility model has the advantages of convenient engineering, excellent adaptability and excellent seal effect.
Description
" technical field "
The utility model relates to a kind of gas-tight sealing device that is used for the cable splice protection, particularly belongs to a kind of shrinkage sleeve pipe that telecommunication cable continues and protects that is used for.
" background technology "
At present, be used for the continue method of protection of telecommunication cable and mainly contain two kinds: the one, the thermal contraction method is promptly assured to cover with thermal contraction in cable splice part and is wrapped up in, and then to its heated baking, makes it fusing and shrinks, thereby finish parcel and sealing to the part that continues.Another kind method is the cold bonding method of twining, and promptly the cable splice part is twined with the adhesive waterproof tape overlap joint, and achieving a butt joint continues swathing of part.Because the thermal contraction method needs burning things which may cause a fire disaster baking, and often environment is comparatively complicated in the job site that telecommunication cable continues, and therefore construction is very inconvenient at the scene, and needs the workman to have certain skilled technical ability, therefore is difficult to guarantee construction quality.And twine the cold bonding method, though construction method is simple, efficient is very low, and the tightness degree of twining is difficult to grasp, and causes construction quality can't be guaranteed equally thus.
" summary of the invention "
The purpose of this utility model promptly is to provide a kind of novel telecommunication cable shrinkage joint coupling, to simplify construction procedure, reaches the raising operating efficiency, guarantees the purpose of construction quality.
Telecommunication cable shrinkage joint coupling disclosed in the utility model, in a tubular form, be set in the continual-connecting-part of telecommunication cable (1), it is characterized in that, be in charge of for two sections by A, B and be socketed to form, every section crust of being in charge of is the shrinkage sleeve pipe (2) that utilizes elastomeric material to make, and shrinkage sleeve pipe (2) is realized predilation by the spiral plastic support pipe (4) that is provided with in it; Described spiral plastic support pipe (4) utilizes auto-buckled type plastic support riglet (5) to be entwined.
Telecommunication cable shrinkage joint coupling disclosed in the utility model when making production, adopts mechanical means that the shrinkage sleeve pipe (2) of moulding is strutted in its elastic range in advance, and the spiral plastic support pipe (4) that winds in advance of packing into then gets final product.When installation, the utility model is set in the telecommunication cable position of continuing, take out the spiral plastic support pipe of separating its inside then.Separate with taking out of spiral plastic support pipe, the shrinkage sleeve pipe shrinks under himself elastic reaction, promptly attached being rolled on the cable, thus finished parcel and sealing to the cable splice position.This shows that the utility model adopts cold-shrink technology, need not to get angry and special tool(s) that easy construction is easily gone; Owing to adopt the predilation technology, the utility model product of same specification is applicable to the cable in multiple line footpath again; Shrinkage sleeve pipe of the present utility model adopts elastomeric material to make, and can provide the constant lasting power of radially holding tightly to the cable splice position, has good gas-tight, sealing, dampproof effect.In a word, the utlity model has the characteristics of the strong and good sealing effect of easy construction, applicability.
" description of drawings "
Accompanying drawing discloses specific embodiment of the utility model, wherein:
Fig. 1, the A section is in charge of structural representation;
Fig. 2, the B section is in charge of structural representation;
Fig. 3, the view of taking out uncoiling formula plastic support pipe in the work progress;
Fig. 4, the utility model view after construction finishes.
" specific embodiment " as shown in Figure 1 and Figure 2, telecommunication cable shrinkage joint coupling disclosed in the utility model is in charge of for two sections by A, B and is socketed to form.Be in charge of all in a tubular form for every section, its crust is the shrinkage sleeve pipe (2) that utilizes elastomeric material to make.So-called elastomeric material can be any one of silicon rubber, latex, fluorubber, ethylene-propylene diene copolymer.The utility model adopts mechanical means that shrinkage sleeve pipe (2) is strutted in its elastic range in advance when making production, and the spiral plastic support pipe (4) of packing into then and winding is in advance realized predilation.Described spiral plastic support pipe (4) utilizes auto-buckled type plastic support riglet (5) to twine after ultrasonic bonding forms.Described auto-buckled type plastic support riglet and the spiral plastic support pipe that processes thereof all have sale in market, belong to public technology, so do not do too much explanation.
As shown in Figure 3, when installation, A of the present utility model, B be in charge of for two sections be set with in the communication cable-end two ends, cable joint is continued finish then, again the A section is in charge of and is moved to the cable splice position, take out the spiral plastic support pipe of separating its inside then.Separate with taking out of spiral plastic support pipe, the shrinkage sleeve pipe that the A section is in charge of shrinks attached being rolled on the cable under himself elastic reaction.Then, the B section is in charge of moves to the cable splice position, overlapping, the overlap joint in the end that its end and A section are in charge of, and then take out the spiral plastic support pipe of separating its inside, separate with taking out of spiral plastic support pipe, the shrinkage sleeve pipe that the B section is in charge of also shrinks attached being rolled on the cable under himself elastic reaction, and also combination is tight for two sections overlapping overlapping parts of being in charge of of A, B, thereby has finished parcel and sealing to the cable splice position.
For strengthening the protection to the cable splice position, the best and supporting use of protective core pipe (3) of the utility model is promptly placed a protective core pipe, to strengthen the resistance to compression effect at this position between cable (1) and spiral plastic support pipe (4).Described protective core pipe (3) can adopt metal tubes such as aluminum pipe, copper pipe, also can utilize non-metallic pipes such as glass reinforced plastic pipe, rubber tube, earthenware.
