Abstract

The utility model relates to a novel optical cable casing, the tube wall of which is a compound structure consisting of an inner layer and an outer layer. The inner layer is made of silica gel and the outer layer is made of polyethylene or other plastics. The outer tube wall is axially provided with two groups of wing-shaped clamping frames which are integrated into a whole with the outer layer of the tube wall, the openings of the clamping frames are in opposite direction; or the outer tube wall is axially provided with two groups of mushroom-shaped plugs which are integrated into a whole with the outer layer of the tube wall, the plugs are in opposite direction and matched with the wing-shaped clamping frame on the neighboring optical cable casing. The utility model is convenient in installation and can avoid mutually wringing of optical cable casing in the laying of optical cable, thereby being convenient in construction, enhancing construction quality and speed and being convenient in maintenance.

Description

A kind of novel cable sleeve

Affiliated technical field

The utility model relates to a kind of cable sleeve.

Background technology

Cable sleeve widespread use in communication cable is laid; it is to the protection cable line; guarantee that the unimpeded of communication signal has great significance; the cable sleeve that uses is normally by tygon or other plastics at present; utilize the inwall of two extruders coextrusion method moulding to scribble the round complex pipe of silica gel; this complex pipe inwall friction factor is little; so intensity is big; good bending property; thereby be subjected to people's favor deeply, however in construction, be circle owing to managing, thereby when many cable sleeves; occur twisting muscle between the cable sleeve easily, optical crosstalk cable and every cable line of identification bring difficulty when giving construction.Quality, speed and the maintenance of construction have been influenced.

Summary of the invention

The purpose of this utility model is to provide a kind of and avoids twisting mutually between the cable sleeve muscle, thereby but convenient construction improves speed of application, quality and a kind of novel cable sleeve easy to maintenance.

The utility model is that the technical scheme that its technical matters of solution is adopted is: a kind of novel cable sleeve, its tube wall is the composite structure that inside and outside layer is formed, inner layer material is a silica gel, cladding material is tygon or other plastics, outer tube wall is axially arranged with two groups of aliform decks that are connected as a single entity with the tube wall skin, and deck bayonet socket direction is opposite; Perhaps outer tube wall is axially arranged with two groups of mushroom plugs that are connected as a single entity with the tube wall skin, and plug direction is opposite, matches with aliform deck on the adjacent cable sleeve; Described deck inner chamber is a mushroom, and bayonet socket has tapering.

The beneficial effects of the utility model are: because the utility model is axially arranged with two groups of opposite aliform decks of opening direction that are connected as a single entity with the tube wall skin at the cable sleeve outer tube wall, perhaps be axially arranged with two groups of opposite mushroom plugs of direction that are connected as a single entity with the tube wall skin at the cable sleeve outer tube wall, and the aliform deck on plug and the adjacent cable sleeve matches, thereby can try first plug with cable sleeve in optical cable laying inserts respectively in the deck of the sleeve pipe that is adjacent, after weaving into multiple combination as required, optical cable once is inserted in gets final product, thereby it is not only easy for installation, and avoided between the cable sleeve twisting mutually muscle, the quality and the speed of construction have been improved, improve tensile strength simultaneously, and kept good performances such as the inwall friction of original sleeve pipe is little.

Embodiment

By Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of novel cable sleeve, tube wall is made up of internal layer 1 and outer 2, the material of internal layer 1 is a silica gel, outer 2 material is a tygon, and outer tube wall is axially arranged with the two groups of aliform decks 3,4 that are connected as a single entity with tube wall skin 2, and bayonet socket 5 directions of deck 3,4 are opposite, inner chamber 6 is a mushroom, and bayonet socket 5 has tapering; Or be axially arranged with the two groups of mushroom plugs 7,8 that are connected as a single entity with tube wall skin 2 along outer tube wall, plug 7,8 matches with the deck 3,4 of adjacent cable sleeve respectively, and the cable sleeve that cable sleeve can not waited by even number equal diameters such as 4,6 or 8 or diameter is independent assortment as required.Can be when the utility model is produced with two extruders with by the novel cable sleeve that scribbles silica gel after the co-extruding machine head coextrusion of pipe section configuration manufacturing by the one step completed inwall of cooling and shaping.

Claims

1, a kind of novel cable sleeve, its tube wall is the composite structure that inside and outside layer is formed, and inner layer material is a silica gel, and cladding material is tygon or other plastics, it is characterized in that outer tube wall is axially arranged with two groups of aliform decks that are connected as a single entity with the tube wall skin, deck bayonet socket direction is opposite; Perhaps outer tube wall is axially arranged with two groups of mushroom plugs that are connected as a single entity with the tube wall skin, and plug direction is opposite, matches with aliform deck on the adjacent cable sleeve.

2, novel cable sleeve according to claim 1 is characterized in that described deck inner chamber is a mushroom, and bayonet socket has tapering.
