Is formed by twisting more than one pair of mutually insulated wires. Compared with an overhead open wire, the communication cable has the advantages of large communication capacity, high transmission stability, good confidentiality, less influence of natural conditions and external interference and the like.
The existing communication cable generally has a plurality of protective layers, and the cable core is well protected, but the material mainly depends on the protective layers and can not meet the use requirement for protecting the cable core, if the cable core is easily extruded, although the protective sleeve of the cable can be made of hard materials, the problem of laying needs to be considered, only a rubber material with high hardness can be selected, the cable core is tightly contacted with the rubber material, and when the cable core is extruded, the rubber material is still extruded to the cable core due to deformation, so that the cable core is damaged.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an aim at just lies in being poor in order to solve above-mentioned communication cable compressive capacity, and the problem of fragile sinle silk provides a communication cable subassembly, has through pressurized expansion mechanism and interior sleeve pipe matched with mode, carries out all-round protection to the sinle silk, improves compressive capacity, extension sinle silk life's advantage.
The utility model discloses a following technical scheme realizes above-mentioned purpose, a communication cable subassembly includes sinle silk, shielding layer and lag from inside to outside in proper order, a serial communication port, the sinle silk with install resistance to compression mechanism between the shielding layer, resistance to compression mechanism include outer tube and interior sleeve pipe and the outer tube with pressurized expansion mechanism between the interior sleeve pipe, pressurized expansion mechanism is used for the outer tube receive towards the inner tube transversely expands during pipe pressure, the sinle silk divide into two sets ofly, a set of place with pressurized expansion mechanism, another group place in interior sheathed tube inside.
Preferably, the pressure resisting mechanisms are distributed at equal intervals on the cable assembly.
Preferably, the compression expansion mechanism comprises an oval structure consisting of two symmetrically attached elastic sheets, the wire core is clamped between the two elastic sheets, and the top and the bottom of the structure are connected with the outer sleeve and the inner sleeve.
Preferably, the shielding layer is an aluminum foil jacket.
Preferably, the protective sleeve is a polyethylene insulating sleeve.
Compared with the prior art, the beneficial effects of the utility model are that: through dividing into the sinle silk two sets of places including in the sleeve pipe, interior sleeve pipe can be protected by outer tube and pressurized expansion mechanism, and another a set of placing is in pressurized expansion mechanism, in case when this cable assembly receives the extrusion, the inner chamber of pressurized expansion mechanism transversely expands and can not produce the extrusion to the sinle silk, protects the sinle silk through interior sleeve pipe and the cooperation of pressurized expansion mechanism each other, has improved the life of cable greatly, has also reduced the damage that the cable caused because of the external reason.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and fig. 2, a communication cable subassembly, from inside to outside include sinle silk 1 in proper order, shielding layer 3 and lag 4, install resistance to compression mechanism 2 between sinle silk 1 and the shielding layer 3, resistance to compression mechanism 2 includes outer tube 5 and interior sleeve pipe 6 and the pressurized expansion mechanism 7 between outer tube 5 and the interior sleeve pipe 6, pressurized expansion mechanism 7 is used for the inner chamber lateral expansion when outer tube 5 receives towards interior sleeve pipe 6 pressure, sinle silk 1 divide into two sets ofly, a set of placing and pressurized expansion mechanism 7, another set is placed in the inside of interior sleeve pipe 6, protect sinle silk 1 through resistance to compression mechanism 2, resistance to compression protection principle is: divide into two sets ofly with sinle silk 1, a set of placing in interior sleeve pipe 6, still separate outer tube 5 and pressurized expansion mechanism 7 between interior sleeve pipe 6 and the shielding layer 3, consequently be difficult to produce deformation extrusion inside sinle silk 1, another a set of placing is in pressurized expansion mechanism 7, pressurized expansion mechanism 7 has when receiving the pressure towards interior sleeve pipe 6, the cavity transversely expands, can not extrude sinle silk 1 because of outer tube 5 deformation like this, consequently, mutually support through interior sleeve pipe 6 and pressurized expansion mechanism 7 and protect sinle silk 1 effectively.
2 equidistance distributions of resistance to compression mechanism are at the cable subassembly, and resistance to compression mechanism 2 is not continuous structure, can practice thrift the cost like this, also need not worry that continuous resistance to compression mechanism 2 influences the cable and bends, makes things convenient for cable laying work.
As shown in fig. 3, the compression expansion mechanism 7 includes an oval structure composed of two symmetrically attached elastic sheets, the wire core 1 is clamped between the two elastic sheets, the top and the bottom of the structure are connected with the outer sleeve 5 and the inner sleeve 6, and the cross section of the cable is a circular structure, so that when the outer sleeve 5 receives extrusion, the stress direction faces the inner sleeve 6, the top and the bottom of the oval structure composed of the compression elastic sheets are changed back, the oval structure is transversely expanded, and the wire core 1 has enough space to be not extruded, thereby protecting the wire core 1 in the compression expansion mechanism 7.
The shielding layer 3 is an aluminum foil outer sleeve which has a good signal shielding effect and enhances the anti-interference performance of the cable, and the protective sleeve 4 is a polyethylene insulating sleeve and has the advantages of high compressive strength and good machining performance.
