Problems solved by technology

However, the arrangement of digital cables and coaxial cables requires a large amount of filling materials, which directly increases the manufacturing cost of the cables; in addition, the cables are only considered to be used in normal temperature or high temperature environments, not in cold environments. , when it is used in a cold area, it is very prone to freezing and cracking, and there is no anti-interference shielding layer outside the digital communication cable, resulting in mutual interference with the external cable, which is difficult for installation and subsequent application. bring many adverse effects

Embodiment Construction

[0017] refer to figure 1 and figure 2 : The present invention includes one coaxial cable A and ten digital cables B. Among them, the coaxial cable A is composed of an inner conductor 1, an insulating layer 2, an outer conductor and a sheath layer 5 from the inside to the outside; the inner conductor 1 is a high-quality bare copper wire; the insulating layer 2 is a physical foamed polyethylene (physical Foaming is an existing conventional technology); the outer conductor is composed of an inner layer of longitudinally wrapped aluminum foil layer 3 and an outer tinned copper wire braid layer 4 (it can also be replaced by an alloy wire braid layer); the sheath layer 5 is low temperature resistant Material. Each digital cable B is composed of a conductor 6 and an insulating layer 7 covering the conductor 6; the conductor 6 is twisted by multiple high-quality bare copper wires (tinned copper wires can also be used instead); the insulating layer 7 is Low temperature resistant ma...

Abstract

The invention discloses a coaxial data composite cable which comprises a coaxial cable and a plurality of digital cables. The digital cables are distributed on an outer wall face of the coaxial cable through a belting layer, a ring is formed with the coaxial cable serving as the centre of a circle, and a shielding layer and a protective sleeve layer are sequentially wrapped on the outside of the belting layer. The coaxial data composite cable enables the coaxial cable and the digital cables to be effectively compounded to form a complex integrated structure, one cable has two transmission functions which are mutually independent and free of interference, mutual interference between the cable and an outside cable is avoided, and the coaxial data composite cable greatly brings convenience to wiring installation and follow-up management, avoids line pipe waste, reduces manufacture cost, installation cost and worker labor intensity, and improves wiring and installation efficiency. Simultaneously, the coaxial data composite cable has good resistance to low temperature, does not dare cold, effectively expands service environment, is favorable to application and dissemination in cold areas, and is strong in practical applicability and high in reliability, and the lowest temperature resistance can reach -60 DEG C.

Description

technical field [0001] The invention relates to cables, in particular to a coaxial data composite cable, which combines a coaxial cable for transmitting video images and a digital cable for digital communication into an integral structure. It is especially suitable for monitoring equipment, and also suitable for other electrical equipment, such as TV, computer, videophone and so on. Background technique [0002] With the rapid development of science and technology, in recent years, monitoring equipment has been widely used in commercial and civil buildings such as shopping malls, shops, financial offices, residential buildings, real estate villas, etc., and has played an escort role in social security management. The monitoring equipment is mainly composed of a front-end part (camera, monitor, etc.), a transmission part and a back-end part (central control equipment, sub-control equipment, etc.), among which, the transmission part is usually composed of two transmission cabl...
