Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following examples with reference to the accompanying drawings:

as shown in fig. 1-3, a composite cable, includes many cable conductor 1, is equipped with around band 2 along the heliciform winding in the periphery of cable conductor 1, is the knitting form interlude winding from many cable conductor 1 around band 2, and the material around band 2 has good compliance and tensile strength, is suitable for high-speed winding, can select for use common fibrous tapes such as mica tape, alkali-free glass fiber area or non-woven fabric area.

According to the mode of the wrapping tape 2, a plurality of cable core wires 1 are regularly connected in series, so that the cable core wires 1 and the cable core wires 1 are mutually associated, and the cable core wires 1 and the wrapping tape 2 are mutually associated, each cable core wire 1 cannot be independently displaced, the integrity among the cable core wires 1 is improved, and the inside of a cable is not easy to loose and deform;

moreover, because the wrapping tape 2 does not completely wrap the cable core 1, the periphery of each cable core 1 still has a part which is not wrapped, so that the integrity of the cable cores is ensured, and the original flexibility of the cable cores is less affected, so that the cable can have excellent bending performance.

Because the wrapping tape 2 is not completely wound, in order to ensure the integrity of the cable, the wrapping angle of the wrapping tape 2 is less than or equal to 45 degrees, and the wrapping area of the wrapping tape 2 is improved as much as possible while the wrapping tape 2 is ensured not to interfere with each other.

For the tensile strength of improvement cable, improve the inside compactness of cable, the periphery cavity department of cable conductor 1 is filled with filling area 3, and this filling area 3 should have good compliance and tensile strength, and is the same with around band 2, can choose for use common fibrous tape such as mica tape, alkali-free glass fiber area or non-woven fabrics area.

In order to improve the tensile strength of the cable and ensure the bending performance of the cable, the peripheries of the cable core wire 1 and the filling belt 3 are coated with a thin steel wire armor 4 with the weaving density of more than or equal to 90 percent;

meanwhile, the outer sheath 5 is sleeved on the periphery of the armor 4, so that the cable is prevented from being corroded by environmental factors, and the mechanical strength, chemical corrosion resistance, moisture resistance, water and immersion resistance, cable combustion resistance and other capabilities of the wire and the cable are improved.

In the production process, a plurality of cable cores 1 enter a stranding device 7 through a wire distributing plate 6, wherein the rotating speed of the wire distributing plate 6 is v1, the rotating speed of the stranding device 7 is v2, v2 is greater than v1, and the cable cores 1 are stranded through the stranding device 7 and become in a spiral winding state;

the wrapping tape roll of the wrapping tape 2 is positioned between the distributing terminal plate 6 and the stranding device 7 and close to the distributing terminal plate 6, the cable cores 1 are still separated, the wrapping tape 2 firstly winds the two cable cores 1 from the inner side, then the wrapping tape 2 penetrates into the inner side from between the two cable cores 1, after one cable core 1 is wound, the two cable cores 1 are wound from the inner side, and the wrapping process is repeated;

in some embodiments, another wrapping method may also be used, as shown in fig. 4, the wrapping tape 2 firstly wraps around two cable cores 1 from the outside, then wraps around two cable cores 1 from the inside, then the wrapping tape 2 penetrates into the inside from between the two cable cores 1, after one cable core 1 is wrapped, wraps around two cable cores 1 from the inside, and then wraps around two cable cores 1 from the outside, and the wrapping process is repeated, a cross-sectional view of the wrapped cable is shown in fig. 5, in order to increase the compactness of the cable, a filling tape 3 may be filled in a cavity of a middle portion of the plurality of cable cores 1, and of course, other wrapping methods are not described herein;

because the cable core 1 is integrally rotated, the wrapping tape roll only needs to move along a specific circular arc track at the side edge of the cable core 1, the wrapping tape 2 is simultaneously tightened under the driving of the integral rotation motion of the cable core 1, and the cable core 1 wound around the wrapping tape 2 is twisted by the wire twisting device 7;

the filling process of the filling belt 3 is not different from the prior art, and the working process is not described in detail.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
