Abstract

The utility model discloses a S type strippable sheath self-supporting butterfly cable relates to butterfly cable technical field, and main aim at easily peels off of oversheath and takes out of butterfly inner sheath. The technical scheme is that the two butterfly-shaped optical cables are arranged in an up-down parallel mode; the outer sheaths are respectively wrapped outside the two butterfly-shaped optical cables in an S-shaped structure; and the first reinforcing piece is arranged between the two butterfly-shaped optical cables and embedded in the central position of the S-shaped structure of the outer sheath.

Description

S-shaped strippable sheath self-supporting butterfly cable
Technical Field
The utility model relates to a butterfly cable technical field especially relates to a S type strippable sheath self-supporting butterfly cable.
Background
As is well known, YD/T1997.1 part 1 of the drop cable for communications: the butterfly-shaped optical cable industry standard is distinguished according to the construction and application scenarios of the optical cable, and there are three general types: the butterfly-shaped optical cable for indoor introduction, the self-supporting butterfly-shaped optical cable for outdoor overhead introduction and the butterfly-shaped optical cable for outdoor pipeline introduction are adopted. Optical cables of three kinds of different structures are applicable to different application scenarios respectively, but the butterfly cable of prior art has the following problem: (1) The indoor butterfly cable is small in size and low in mechanical performance requirement, and the outdoor butterfly cable is large in size and high in mechanical performance requirement. And (2) the self-supporting butterfly cable can be used for outdoor overhead at a short distance. (3) The outer sheath of the conventional self-supporting butterfly cable is difficult to peel off, and a rubber thread in the butterfly cable is difficult to take out. Therefore, with the continuous deepening of the network construction in China, the research and development of novel optical cables are promoted, and the novel optical cables need to be provided so as to meet the requirements of the market on the characteristics of environmental requirements, line safety, convenience in maintenance and the like.
Disclosure of Invention
In view of this, the utility model provides a sheath self-supporting butterfly cable is peelably to S type, main aim at easy the peeling off of oversheath and taking out of butterfly inner sheath.
In order to achieve the above object, the utility model mainly provides the following technical scheme:
an embodiment of the utility model provides a S type strippable sheath self-supporting butterfly cable. It includes:
the two butterfly-shaped optical cables are arranged in an up-down parallel mode;
the outer sheaths are respectively wrapped outside the two butterfly-shaped optical cables in an S-shaped structure;
and the first reinforcing piece is arranged between the two butterfly-shaped optical cables and embedded in the central position of the S-shaped structure of the outer sheath.
As described above, each of the two butterfly-shaped optical cables includes an optical fiber ribbon, two second reinforcements disposed on two sides of the optical fiber ribbon, and a butterfly-shaped inner sheath wrapped outside the optical fiber ribbon and the two second reinforcements.
As previously mentioned, the second reinforcement is a non-metallic reinforcement.
As mentioned above, the outer sheath is made of black HDPE material.
As mentioned above, the portion of the butterfly-shaped optical cable wrapped by the outer sheath is in a rectangular structure with one side open.
As mentioned previously, the first reinforcement comprises two steel wires arranged side by side.
As mentioned above, the two wires are adhesively connected to the outer sheath.
Borrow by above-mentioned technical scheme, the utility model discloses a S type strippable sheath self-supporting butterfly cable has following advantage at least:
the S-shaped strippable sheath self-supporting butterfly cable is in an S-shaped structure by arranging the outer sheath and is respectively wrapped outside the two butterfly cables, so that 2 butterfly inner sheaths are wrapped and embedded in the S-shaped outer sheath, the S-shaped outer sheath is difficult to strip compared with the conventional self-supporting butterfly cable outer sheath, the S-shaped outer sheath is embedded, the wrapped and embedded butterfly inner sheaths can be more easily separated, and the butterfly cables are internally provided with optical fiber ribbons, so that a plurality of optical signals can be transmitted; and the utility model discloses improve the production efficiency of optical cable greatly, simplify the lectotype of optical cable, can carry out multichannel light signal transmission through an optical cable, also can reduce the degree of difficulty and the production and the construction cost of construction.
The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.

Fig. 1 is a schematic structural view of the S-shaped peelable sheath self-supporting butterfly cable of the present invention.
Detailed Description
To further explain the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.
As shown in fig. 1, an embodiment of the present invention provides an S-shaped peelable sheath self-supporting butterfly cable, which includes: two butterfly cables 1, an outer jacket 2 and a first strength member 3.
The two butterfly-shaped optical cables 1 are arranged in an up-down parallel mode; specifically, two butterfly-shaped optical cables 1 all include optic fibre area 11, set up two second reinforcements 12, the parcel of optic fibre area 11 both sides is in the butterfly inner sheath 13 of optic fibre area 11 and two second reinforcements 12 outsides the utility model discloses in, second reinforcement 12 is nonmetal reinforcement. The outer sheaths 2 are respectively wrapped outside the two butterfly-shaped optical cables 1 in an S-shaped structure; the utility model discloses in, oversheath 2 adopts black HDPE material to make, can satisfy outdoor built on stilts etc. adverse circumstances. The outer sheath 2 wraps the butterfly-shaped optical cable 1 and is of a rectangular structure with an opening at one side. The first reinforcing piece 3 is arranged between the two butterfly-shaped optical cables 1 and embedded in the central position of the S-shaped structure of the outer sheath 2. The utility model discloses in, first reinforcement 3 includes two steel wires 31 that set up side by side, and its modulus of emergence of steel wire for non-metallic member is many, and under the circumstances that provides the same pulling force, the external diameter of steel wire is littleer, so the external diameter of optical cable also can obtain minimum optimal design. The two steel wires 31 are connected with the outer sheath 2 in an adhesive mode, so that the bending resistance of the optical cable in overhead laying can be effectively improved, and the shrinkage of the optical cable sheath can be effectively prevented.
