Description

A kind of novel photoelectric composite cable

Technical field

The utility model relates to field of telecommunications cables more particularly to a kind of novel photoelectric composite cables.

Background technique

The photoelectric mixed cable produced at present have the following deficiencies: it is outer it is abnormal be unfavorable for construction, the unreasonable conductor of internal structure Heat dissipation effect is poor, cumbersome the production cost increases for structure.

Therefore, it is necessary to provide a kind of novel photoelectric composite cable, it is not required to SZ stranding, structure is simple, good heat dissipation effect.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of novel photoelectric composite cable.

The utility model provides a kind of novel photoelectric composite cable, adopts the following technical scheme that

A kind of novel photoelectric composite cable, the novel photoelectric composite cable include fiber cores 1, are bonded 1 appearance of fiber cores The casing 2 of face setting, is not bonded the unit piece 3 being arranged in outside described sleeve pipe 2, and unit piece 3, the skeleton set outside casing 2 is arranged in 4, the outer jacket 5 outside skeleton set 4 is set；The unit piece 3 is not less than 2mm at a distance from casing 2；The skeleton set 4 is by interior The casing that the ring skeleton set 41 of wall fitting 3 outer surface of unit piece setting and the center in section are overlapped with the center of circle in 2 section of casing 42 composition of skeleton set；The ring skeleton set 41 is connected with casing skeleton set 42.

It is described to there is 3-5 unit piece 3 not to be bonded setting outside described sleeve pipe 2.

The skeleton set 4 is made of elastic abrasion-proof material.

The skeleton set 4 is made of high density polyethylene (HDPE).

The outer jacket 5 is made of fire proofing.

The fiber number of the fiber cores 1 is 2-144 core.

Unit piece 3 is single strand of copper wire cable.

Compared with the relevant technologies, the utility model is had the following technical effect that

The utility model can be not required to SZ stranding, only need sheath process 2 times moldings, and structure is simple, good heat dissipation effect.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model embodiment 1；

Fig. 2 is the structural schematic diagram of the utility model embodiment 2.

Specific embodiment

Below in conjunction with drawings and embodiments, the utility model is described in further detail.

A kind of novel photoelectric composite cable of the utility model, the novel photoelectric composite cable include fiber cores 1, fitting The casing 2 of 1 outer surface of fiber cores setting, is not bonded the unit piece 3 being arranged in outside described sleeve pipe 2, is arranged in unit piece 3, casing 2 Outer skeleton set 4, is arranged in the outer jacket 5 outside skeleton set 4；The unit piece 3 is not less than 2mm at a distance from casing 2；The bone Frame set 4 is covered the center of circle weight at the center and 2 section of casing in 41 and section by the ring skeleton of inner wall fitting 3 outer surface of unit piece setting 42 composition of casing skeleton set of conjunction；The ring skeleton set 41 is connected with casing skeleton set 42.

There are not less than at a distance from 2mm between casing 2 for unit piece 3, it is ensured that heat dissipation, and meanwhile it is inclined by being carried out when external force Heart becomes, and energy protection sleeve pipe 2 is not damaged.

The ring skeleton set 41 of skeleton set 4 can guarantee that unit piece 3 is not damaged, while make to begin between unit piece 3 and casing 2 There are distances eventually, guarantee heat dissipation, and casing skeleton set 42 can guarantee that casing 2 is not damaged.

Embodiment 1

In the present embodiment, described to have 4 unit pieces 3 not to be bonded setting outside described sleeve pipe 2, the skeleton set 4 is by bullet Property wear-resistant material be made, the outer jacket 5 is made of fire proofing, and the fiber numbers of the fiber cores 1 is 2-144 core, unit Part 3 is single strand of copper wire cable.

Different number of unit piece 3 is set, it can be made to be not easy to cause fiber cores impaired due to by external force.

Embodiment 2

In the present embodiment, described to have 5 unit pieces 3 not to be bonded setting outside described sleeve pipe 2, the skeleton set 4 is by height Density polyethylene is made, and the outer jacket 5 is made of fire proofing, and the fiber number of the fiber cores 1 is 2-144 core, unit Part 3 is single strand of copper wire cable.

At the same time it can also preparing outer jacket 5 using different materials according to different requirements, make it have different anti- Protect effect.

In the preparation, casing 2 and unit piece 3 enter sheath head extrusion molding to the utility model simultaneously, and skeleton covers 4 frameworks Using, at circular optical cable, being not required to SZ stranding after secondary sheath.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other relevant technical fields, are also included in the patent protection scope of the utility model.
