Abstract
The utility model relates to the field of communication, and provides an integrated cable used for a video camera. The integrated cable used for the video camera is composed of a video line and a power line. The video line is composed of four twisted pair video lines, an aluminium foil mylar and a fixing sleeve. The aluminium foil mylar winds around the twisted pair video lines. The four twisted pair video lines are distributed in a delta-shaped mode. The four twisted pair video lines are embedded in the fixing sleeve. The fixing sleeve is a TPE elastomer plastic cement layer which wraps the four twisted pair video lines in a plastic extrusion mode. The power line is composed of a two-core power line and an insulation sleeve. The insulation sleeve is a TPE elastomer plastic cement layer which wraps the two-core power line in a plastic extrusion mode. The integrated cable also comprises an external layer integral body sheath, of which a cross section is elliptical. The external layer integral body sheath is a hard rubber layer which wraps the two-core power line and the two-core power line in a plastic extrusion mode. The twisted pair video lines and the two-core power line are parallel to each other.
Description
Technical field
The utility model relates to the communications field, and concrete is the cable after a kind of integration.
Background technology
At present in the time of the picture pick-up device of arranging in the systems such as CHINA RFTCOM Co Ltd and video monitoring, video line and power line are all independent wiring, this not only needs to take very large depositing and installing space, simultaneously because circuit is numerous and diverse, entangled to each other, make workload multiplication, and for the dollying head on the equipment such as elevator and lift, complicated wiring can make accident occurrence frequency raise.In addition, traditional side signal transmission case is to use video coaxial cable, but in engineering reality, use video line signal transmission often to have many unsatisfactory places: various supervision scene is all certainly existing strong or weak electromagnetic interference, because having determined it, the characteristic of coaxial cable is easy to be interfered, thereby affected final picture quality, the various performances of system equipment can not get performance; More than transmission range to 200 meter, especially three, when more than 400 meters, the signal attenuation especially decay of high-frequency signal is serious, and picture quality further declines, and must adopt more high-grade coaxial cable, causes transmission cost significantly to rise; The monitoring point of transmission range between 600-1500 rice, even if disregard into the local cable that adopts high volume, thick core, installs various same y axis amplifier ies additional, is also difficult to obtain good effect; Because coaxial line is harder, and engineering project that distance longer many for monitoring point, poling cable wiring manufacture difficulty, central monitoring position has become electric wire stockyard, affects attractive in appearance; In mobile environments for use such as elevators, if use common video coaxial line, video core easy fracture, be generally 3～5 months service time, needs the frequent cable of changing, use cost is high; The power line of video monitoring system routine lays separately, causes system wiring to come and go repeatedly, and total system cost height is uneconomical.
Utility model content
Technical problem to be solved in the utility model is exactly, for the existing deficiency of prior art, and the cable that provides a kind of power line and twisted-pair visual frequency line to integrate, this cable has not only alleviated the workload of wiring, having saved line takes up space, and the fail safe that has improved whole system, can also meet the requirement of different operating distance simultaneously.
The utility model solves its technical problem underlying and realizes by the following technical solutions.This novel a kind of video camera providing is with integrating cable, formed by video line and power line, video line is by four twisted-pair visual frequency lines, aluminium foil wheat is drawn with fixed cover and forms, aluminium foil wheat is drawn and is wound around twisted-pair visual frequency line, article four, twisted-pair visual frequency line is isosceles triangle distribution, article four, twisted-pair visual frequency line embeds in fixed cover, fixed cover is the TPE elastomer plastic layer of four twisted-pair visual frequency lines of extrusion molding parcel, power line is made up of two core power lines and insulating case, insulating case is the TPE elastomer plastic layer that extrusion molding wraps up two core power lines, it is oval-shaped outer Integral shield sleeve that integration cable also includes cross section, outer Integral shield sleeve is the vulcanie layer of extrusion molding parcel twisted-pair visual frequency line and two core power lines, twisted-pair visual frequency line and two core power lines are arranged parallel to each other, outer Integral shield sleeve and separate is stretched out near junction in the two ends of twisted-pair visual frequency line and two core power lines.
Better, the extension elongation of above-mentioned twisted-pair visual frequency line is greater than the extension elongation of two core power lines.
Integrate the resistance to overturning of cable in order to improve, twisted-pair visual frequency line and two core power lines are mutually stranded, and under the very stable condition of cable environment for use, twisted-pair visual frequency line and two core power lines also can be arranged in parallel.The two ends of twisted-pair visual frequency line and two core power lines are all provided with the jointing with relevant device separately, in the part near joint, twisted-pair visual frequency line and two core power lines stretch out outer Integral shield sleeve and separate, so in use, can be according to the needs of distance, outer Integral shield sleeve is cutd open and cut, make the extension elongation of twisted-pair visual frequency line and two core power lines meet required distance, generally, because video equipment has motility, the extension elongation of twisted-pair visual frequency line all will be longer than the extension elongation of two core power lines.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to having adopted twisted-pair visual frequency line and the relatively independent integrated measures of two core power lines in this scheme, make a novel integration cable providing alleviate the workload of wiring, saving line takes up space, when improving security of system, can meet the requirement of different operating distance, and maximum functional distance is 1000 meters of left and right, compared with traditional coaxial line video line, improve nearly 100% the useful life in elevator monitoring, simultaneously, the technical program adopts the cooperatively interacting of rubber of flexible TPE plastics and hard, improve the impact resistance of cable, intensity and the toughness of cable are increased, aluminium foil wheat is drawn the effectiveness that provides good, play the effect that keeps long range signals transmission fidelity.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
