Abstract

An outdoor self-sustaining armor wire, including a core wire and a first outer sheath, characterized in that two first self-sustaining armor wires are symmetrically arranged inside the outer sheath, and a metal flexible wire is arranged in the center of the first outer sheath. The core wire is arranged in the metal hose, the second outer sheath is connected to the second outer sheath through the connecting part on one side of the first outer sheath, and the second self-holding armor wire is fixed inside the second outer sheath. The feature of this structure is that the core wire is mainly protected by the first outer sheath and the inner metal hose, and the rigidity of the overall cable is further increased by the second outer sheath and the second self-holding armor wire. and toughness. It has a very high self-sustaining force, and can be threaded and advanced in various small holes and pipes conveniently. The high toughness also ensures that the inner core wire will not be damaged when the threading advance encounters obstacles, making it more suitable For the vertical deployment of high-rise buildings, the final stripping and switching is also very convenient.

Description

Outdoor self-sustaining armor wire

technical field

The utility model relates to a cable, in particular to an outdoor self-supporting armored cable.

Background technique

In today's cities, all kinds of cables are as complex and dense as spider webs, and finally connect power, signals, etc. from the backbone network to end users, and the cables need to go through various bends. In existing cables, the inner transmission core wire is generally protected by an outer protective rubber sheath. This kind of protection can only provide a small anti-bending protection, and it will yield when encountering a large bending angle, which directly leads to the breaking of the internal cable. In general, it has been unable to adapt to the needs of today's society. On the other hand, due to the different indoor and outdoor environments, generally the indoor space is smaller and the corners are more, which requires the cable to have greater bendability, while the outdoor space is larger and the environment is relatively harsh, so the used cable It is relatively hard, and the protective rubber sleeve is also thicker. The two different usage environments make it impossible for the existing cables to be directly pushed from the outdoors to the indoors. They need to go through a certain branch line to get off the car and transfer, which increases the labor cost of wiring and also affects the transmission quality under certain circumstances.

Utility model content

In order to solve the above problems, the utility model provides an outdoor self-sustaining armor wire with strong bending and tensile resistance, good self-sustaining force, and can be directly pushed into indoor use after simple treatment.

In order to achieve the above object, an outdoor self-holding armor wire is designed, including a core wire and a first outer sheath, and it is characterized in that the inside of the outer sheath is symmetrically provided with two first self-holding armor wires. A metal hose is arranged in the center of the metal hose, and a core wire is arranged in the metal hose, and a second outer sheath is connected to one side of the first outer sheath through a connecting part, and a second self-holding armor wire is fixed inside the second outer sheath. The feature of this structure is that the core wire is mainly protected by the first outer sheath and the inner metal hose, and the rigidity of the overall cable is further increased by the second outer sheath and the second self-holding armor wire. and toughness.

In order to further clarify the functions of each part, the first outer sheath is rectangular, the second outer sheath is circular, the diameter of the second self-sustaining armor wire is larger than the first self-sustaining armor wire, and the thickness of the connecting part is smaller than the first The width of the outer sheath. The thinner connection also facilitates separation of the first outer sheath and the second outer sheath.

In order to facilitate stripping, a V-shaped stripping opening is provided between the first self-sustaining armor wire and the metal hose on the side of the first outer sheath away from the connection part.

A further solution is that the core wire is an optical fiber.

The outdoor self-sustaining armor wire designed by the utility model has the following characteristics: 1. Good mechanical toughness and strong protection ability for the core wire; 2. Easy to strip; 3. Good self-sustaining force; 4. Long service life; 5. The first outer sheath and the second outer sheath are easily separable. To sum up, the outdoor self-sustaining armored cable obtained in this utility model is used in the last two kilometers of the network layout, and the structure contained in the second outer sheath is particularly suitable for wiring in the air in the community, and when the cable needs to be pushed into the room , then the first outer sheath and the second outer sheath can be separated, and only the first outer sheath and its internal structure are reserved. Since the first outer sheath also has two symmetrical first self-sustaining armor wires inside, there are The extremely high self-sustaining force can facilitate the threading and advancing in various small holes and pipes, and the high toughness also ensures that the inner core wire will not be damaged when the threading advance encounters obstacles, which is more suitable for The vertical deployment of high-rise buildings and the final use of stripping and switching are also very convenient.
