Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 to 2, the present invention provides a hybrid cable, including:

at least one set of cable units including a first power line 110 and a second power line 120;

the butterfly cable unit 200 is provided with an optical fiber 210 inside the butterfly cable unit 200;

the thin-wall outer sheath 300 is wrapped on the outer sides of the butterfly cable unit 200 and the cable unit;

the connecting part 400 is used for connecting the butterfly cable unit 200 and the thin-wall outer sheath 300;

wherein, the butterfly cable unit 200, the thin-wall outer sheath 300 and the connecting part 400 are integrally formed; two ends of the butterfly cable unit 200 are connected with the inner wall of the thin-wall outer sheath 300 through the connecting part 400 respectively; in the connecting part 400, at least one first gap 500 is arranged at the position where the connecting part 400 is connected with the butterfly cable unit 200; the connecting part 400 and the thin-wall outer sheath 300 are torn along the connecting part 400 and the butterfly cable unit 200; the outer shape of the photoelectric hybrid cable is oval.

Specifically, the photoelectric hybrid cable adopts the butterfly cable unit 200 and the thin-wall outer sheath 300 which are integrally formed, so that the butterfly cable unit 200 and the thin-wall outer sheath 300 are simultaneously prepared by one process, the working hours are saved, and the manufacturing cost is reduced. In addition, the butterfly cable unit 200 and the thin-walled outer sheath 300 can be torn at the position of the connection part so as not to affect the separation of the butterfly cable unit 200 and the thin-walled outer sheath 300 during use.

In conclusion, on the premise that the installation and use functions are not affected, the butterfly cable unit 200 and the thin-wall outer sheath 300 are integrally formed, so that the working time is saved, the manufacturing efficiency is improved, and the manufacturing cost is reduced.

Further, the butterfly cable unit 200 and the thin-wall outer sheath 300 are integrally formed by using the same material, and the butterfly cable unit 200 and the cable unit are made of different materials.

Specifically, in the use process of the photoelectric hybrid cable, after the cable is laid, the head of the cable is connected with the equipment to be installed, at the moment, the thin-wall outer sheath 300 with the length of 10-20 cm of the head of the cable needs to be peeled off, so that the butterfly cable unit 200 and the cable unit wrapped inside the thin-wall outer sheath 300 are exposed, and finally, the exposed butterfly cable unit 200 and the exposed cable unit are independently connected with the power supply part and the optical fiber part of the equipment to be installed. It can be seen that the butterfly cable unit 200 and the cable unit need to be separately installed when they are separately connected with the device to be installed, so they cannot be adhered together. In some embodiments, in order to avoid the adhesion between the butterfly cable unit 200 and the cable unit, between the thin-wall outer sheath 300 and the butterfly cable unit 200, and between the thin-wall outer sheath 300 and the cable unit, an isolation layer is often disposed therebetween, which substantially increases the manufacturing cost. In the hybrid cable, the butterfly cable unit 200 and the thin-walled outer sheath 300 are integrally formed during preparation, so that the butterfly cable unit 200 and the thin-walled outer sheath 300 can be manually separated at the position of the connecting part 400 before the butterfly cable unit 200 is connected with equipment to be installed, and the butterfly cable unit 200 and the thin-walled outer sheath 300 cannot be adhered to each other. The butterfly cable unit 200 and the cable unit are made of different materials, so that the adhesion of the butterfly cable unit and the cable unit is avoided (the butterfly cable unit and the cable unit are easily adhered to each other by the same material). In the same way, the cable unit and the thin-wall outer sheath 300 are not adhered to each other.

Further, the first gap 500 is provided on the side wall of the connection part 400; the first gap 500 comprises a first side surface 510 and a second side surface 520 which are connected with each other, the first side surface 510 is connected with the side wall of the butterfly cable unit 200, the second side surface 520 is connected with the side wall of the connecting part 400, and the first side surface 510 and the second side surface 520 form a preset included angle alpha; the side wall of the butterfly cable unit 200 connected to the first side surface 510 is the first side wall 220, and the first side surface 510 and the first side wall 220 are in the same plane. The side wall of the connecting portion 400 connected to the second side surface 520 is the second side wall 410, and the second side surface 520 is disposed at an angle (referred to as a first angle β) with respect to the second side wall 410.

Specifically, the first notch 500 is designed to facilitate tearing and peeling of the connecting part 400, so that the butterfly cable unit 200 is separated from the thin-wall outer sheath 300; in addition, the first side surface 510 of the first gap 500 is coplanar with the first side wall 220 of the butterfly cable unit 200, so that the fracture left on the end surface of the butterfly cable unit 200 after the connecting part 400 is stripped tends to be coplanar with the first side wall 220. I.e., such that the discontinuity and the first sidewall 220 smoothly transition to form a flat surface. The shape of the butterfly cable unit 200 is further ensured, so that the butterfly cable unit is convenient to mount with equipment to be mounted by using standard parts subsequently.

Further, the number of the first gaps 500 is two, the two first gaps 500 are symmetrically arranged along the width direction of the butterfly cable unit 200, and the shortest distance between the two first gaps 500 along the width direction of the butterfly cable unit 200 is 0.2-0.3 mm.

Specifically, two first slits 500 are provided, so that the installer does not need to perform any direction when tearing and peeling. In addition, the design of the two first gaps 500 is more convenient for tearing the connecting part 400 from the first gap 500, so that a flat fracture is further formed on the end face of the butterfly cable unit 200 after the connecting part 400 is peeled off, and the butterfly cable unit 200 and the equipment to be installed are further convenient to install by using a standard component.

Further, at least one second tooth-shaped notch 310 is formed in the outer wall of the thin-wall outer sheath 300 along the circumferential direction of the outer wall, and the second notch 310 extends in parallel to the axial direction of the thin-wall outer sheath 300. For example, four second openings 310 may be disposed on the outer wall of the thin-walled outer sheath 300, and the four second openings 310 are disposed symmetrically along the axis center of the thin-walled outer sheath 300.

Specifically, the thin-wall outer sheath 300 can be torn and peeled off at the second notch 310 in the using process, so that the thin-wall outer sheath 300 can be further conveniently and rapidly peeled off manually, the construction time is saved, and the construction efficiency is improved.

Further, the wall thickness of the thin-wall outer sheath 300 is 0.3-0.4 mm. For example, the thin-walled outer sheath 300 is made of an anti-UV low-smoke halogen-free material, and when the thickness of the thin-walled outer sheath 300 is in the range of 0.3-0.4 mm, the tearing force is less than or equal to 13N.

Specifically, the wall thickness of the thin-wall outer sheath 300 ranges from 0.3mm to 0.4mm, so that the weight of the hybrid cable is reduced, and the hybrid cable is convenient to lay; on the other hand, the butterfly cable unit can be conveniently and manually torn and stripped quickly, the thin-wall outer sheath 300 does not need to be torn and stripped by means of tools, damage to the butterfly cable unit 200 and the cable unit 100 caused by the fact that the butterfly cable unit is torn and stripped by means of tools such as a blade is avoided, and construction efficiency is improved.

Further, the butterfly cable unit 200 is disposed along a minor axis of the elliptical hybrid cable, and the first power line 110 and the second power line 120 are symmetrically distributed on two sides of the butterfly cable unit 200 along a major axis of the hybrid cable.

Specifically, the butterfly cable unit 200 is vertically disposed, and the first power line 110 and the second power line 120 are symmetrically disposed on both sides of the butterfly cable unit 200. On one hand, the photoelectric hybrid cable is attractive, on the other hand, the internal arrangement of the photoelectric hybrid cable is more compact according to the appearance of the oval photoelectric hybrid cable, and the sectional area of the photoelectric hybrid cable is reduced.

Further, the butterfly cable unit 200 includes a cable body 230, both sides of the cable body 230 are opened with tearing openings 231, and the first power line 110 and the second power line 120 are respectively disposed at the tearing openings 231 at both sides of the cable body 230.

Specifically, the design of the tear opening 231 facilitates the stripping of the cable body 230, thereby exposing the optical fiber 210 for connection with the installation device; on the other hand, the first power supply line 110 and the second power supply line 120 are installed at the tear 231, so that the present hybrid cable is more highly integrated, further reducing the diameter of the present hybrid cable.

Further, two reinforcing members 240 are provided, the two reinforcing members 240 are respectively disposed on two sides of the optical fiber 210, and the cable body 230 is covered outside the optical fiber 210 and the reinforcing members 240.

In particular, the further butterfly cable unit 200 of the reinforcement 240 increases the strength of the butterfly cable unit 200.

Further, the reinforcing member 240 is made of a non-metallic material.

In particular, non-metallic strength members 240 may reduce the impact on the optical fiber 210 communication and cable unit power.

Further, the outer sides of the first power line 110 and the second power line 120 are wrapped by an insulating layer 600, and the colors of the insulating layers 600 of the first power line 110 and the second power line 120 are different. For example, the first power source is a live wire, and the insulating layer 600 wrapped around the outside thereof is colored red. The second power source is the neutral wire and the insulation 600 wrapped around its outside is blue.

Specifically, in the process of connecting the first power line 110 and the second power line 120 to the device to be installed, it is convenient for a constructor to quickly distinguish the first power line 110 from the second power line 120.

Further, the insulating layer 600 is made of PVC; the butterfly cable unit 200, the thin-wall outer sheath 300 and the connecting portion 400 are made of anti-UV low-smoke halogen-free materials.

Specifically, the butterfly cable unit 200, the thin-wall outer sheath 300 and the connecting portion 400 are integrally formed, and the three are made of the same material, for example, low smoke and zero halogen material is adopted. Thus, the device can be used indoors and outdoors. And the insulating layer 600 is made of PVC. In this way, the insulating layer 600 is made of a different material from other components (the butterfly cable unit 200, the thin-walled outer sheath 300 and the connecting portion 400), and the butterfly cable unit 200 is further prevented from being adhered to the insulating layer 600 in the process of manually peeling off the thin-walled outer sheath 300.
