Abstract

The utility model discloses a connecting sleeve for a communication cable, belonging to the technology of cable communication cable. The aim of the utility model is to alter the bygone way of nested one time sleeve splice, providing a waterproof connecting sleeve with side mount structure maintained conveniently. Two metallic support strips 6 are arranged symmetrically on the both sides of the cable joint outside a butyl rubber snap ring 12 for supporting, locked through a screw bolt 8, and inserted into chelating clips 7 and 9 in one side opening sheathing 3, composing side mount structure. The utility model has the advantages of convenient maintenance and low cost.

Description

The communication cable cover that continues

The utility model belongs to the wire communication cable technology.

At present, in wire communication cable joint joint, generally adopt the sleeve splice way of totally-enclosed suit.For example metal sleeve or memory plastic bushing, two kinds of sleeve pipes all need to tighten up with the on-the-spot baking of blowtorch and seal, and it is tight to add the plastic adhesive tape envelope then, and its I﹠M is inconvenience all.Though the memory plastics are the new materials of meeting thermal contraction, but still are suit, very fast sometimes generation drainage after the installation, breakdown maintenance also must be taken recast apart.

The disposable sleeve that the utility model purpose is the to change suit in the past way that continues proposes the cover that continues of not only waterproof but also side assembling structure easy to maintenance.

The utility model purpose is achieved in that

A kind of communication cable cover that continues, it is characterized in that cable 12 joint bilateral symmetry be installed on have two strip metal support bars 6 to support outside the butyl rubber snap ring 11 and with bolt 8 lockings after be plugged in the side assembling structure of chelating negative and positive geometrical clamp 7,9 formations in the side opening sheath 3; Described sheath 3 is used waterproof stripping 2 jam-packs at the side opening place, having inside and outside two layers of different materials adhesive tape 1 to tightly wrap with cable external tapping place, outside with shell 4 parcels at sheath 3, sheath 3 has 2 point covers, the taper small apical sleeve is made backup branch cable channel outlet, the big sharp interplanting leader cable channel outlet of taper.

Described shell 4 has several stress predeformation fin reinforcements 41 for ease of the side opening of installing and the port has anticreep to protect along 42, and takes out tightly with the unidirectional bundle tape wrap 5 of taking out tight pawl.

On the described chelating folder 7,9 tapping screw hole 10 is arranged, to connect ground wire.

In conjunction with the accompanying drawings, further specify the utility model content.

Fig. 1 the utility model assembling assembling stereogram;

Fig. 2 the utility model profile.

Identifier is as follows among the figure:

1 inside and outside two layers of different materials adhesive tape, 2 waterproof strippings, 3 side opening sheaths

4 side opening shells, 41 fin reinforcements, 42 anticreeps protect the edge

5 bundle tape wraps, 6 metallic support bars, 7 chelatings sun geometrical clamp

Edge, 8 chelating geometrical clamp bolts, 9 chelatings cloudy geometrical clamp 91 chelating geometrical clamps location

10 shielding tapping screw hole 11 butyl rubber bar snap rings, 12 cables

Fig. 1 is the utility model installation diagram. The utility model connecting sleeve left-right symmetry, left-hand component is connecing of assembling among the figure Continuous cover outline drawing, right-hand component is the split part drawing. From the appearance, shell 4 wrap jacket 3, sheath 3 is wrapping cable 12, Cable and sheath 3 external tapping places tightly wrap with inside and outside two layers of different materials adhesive tape 1. Be plugged with the waterproof stripping in protecting band 3 open lower side 2. From the split part drawing, cable 12 is tied with butyl rubber bar snap ring 11, and snap ring is other to have chelating negative and positive geometrical clamp 7,9 to clamp Cable, about two chelating negative and positive geometrical clamps tighten with bolt 8, and be inserted into after linking to each other with two metallic support bars 6 and protect In the cover 3, the two is by chelating folder positioned edge 91 location. Shell 4 parcels are arranged outside the sheath 3. The side opening sheath has been characterised in that 2 point covers, the ox horn small apical sleeve of sealing are made backup branch line channel outlet, the big point cover of the tapered opening sheath cable passage of deciding Outlet. In addition, shielding tapping screw hole 10 is arranged, to connect earth connection on one of them chelating folder; There are several to answer on the shell 4 Power predeformation fin reinforcement 42, close two muscle also have bundle tape wrap 5 skid-resistant functions; To be that pawl is unidirectional take out bundle tape wrap 5 Taut band can bind shell; Outside metallic support bar 6 and bolt 8, material generally all is ambroin.

By the way, the screw of locking chelating negative and positive geometrical clamp bolt is locked on the chelating sun geometrical clamp with a steel spring sheet, When aerial work is installed or keeped in repair, avoid toner screw.

As follows in the Specific construction process:

Cable connector both sides earlier symmetrical the subsides twine butyl rubber bar snap ring 11, make the cable axial restraint; Again with 2 strip metal supports 6 are arranged The chelating negative and positive geometrical clamp 7,9 that supports is radially fixing. Chelating folder is with bolt 8 lockings, respectively is inserted into a side about then to open In the mouth sheath 3. Sheath 3 opening parts are with water-tight stripping 2 jam-packs, again with butyl rubber band and PVC tape with sheath 3 with The cable external tapping divides ectonexine to tightly wrap. Last sheath is wrapped with side opening shell 4, and takes out tightly with bundle tape wrap 5.

Fig. 2 is the utility model profile. The left side is only to cut shell 4 open, exposes the complete profile of sheath, and is fixing at the chelating sun Shielding tapping screw hole 10 on the folder 7 has revealed. The right is to cut shell 4 open, cuts again sheath 3 open, has shown sheath 3 And the assembly relation between the cloudy geometrical clamp 9 of chelating and the waterproof stripping 2. As can be seen from this figure, the chelating geometrical clamp is plugged in and protects In the cover 3, waterproof stripping 2 plugs are on the side opening of sheath 3. Chelating geometrical clamp 7,9 and sheath 3 between protect along 42 by anticreep The location. Fin on the shell 4 is stress predeformation reinforcement 41, the crack of two paired reinforcements, and just bundle is put to tie and is twined Be with 5, make about it and do not slide.

The utility model advantage:

1, side plug-in mounting does not need the blowtorch heating, installs and keep in repair all to make things convenient for, and can be repeatedly used.

2, mechanical fasteners, and have that butyl rubber band and PVC tape are double-deck to be twined, and the sheath side opening is plugged with the waterproof stripping, so good water-proof effect.

3, mainly adopt plastics, cost is low, good insulation preformance.

Embodiment

Except metallic support bar and bolt, shell 4, sheath 3, geometrical clamp 7,9, waterproof stripping 2 is all made of plastic, presses Fig. 1 assembling, and water-tight adopts 40 * 150mm butyl rubber band and 20 * 30mmPVC adhesive tape to be divided into inside and outside two layers and twines sheath 3 and cable external tapping.Unidirectional 5 three of the tight bundle tape wraps of taking out of shell 4 fastening usefulness 10 * 2500mm are tied up tightly.Logical 200 pairs of telephone wires of big point cover of sheath 3, the logical 10 pairs of telephone wires of small apical sleeve are to dividing the user.Through using, respond well.
