Abstract
The invention relates to a multiplex type combined cable applied to security and protection monitoring and relates to the technical field of cables for security and protection monitoring, in particular to the aspect of the structural improvement of a combined cable used for being connected with a video camera to transmit video signals and supply power to the video camera. The multiplex type combined cable overcomes the technical defects that when an existing coaxial cable comprising a shielding layer and a power line are used in combination, resources are wasted, consumable items are many, and cost is high. The multiplex type combined cable comprises a coaxial cable and is characterized by further comprising a positive power line fixedly connected with the coaxial cable side by side. A negative supply lead electrically connected with the shielding layer of the coaxial cable is further arranged at the part away from the end of the coaxial cable by 10-30 cm. The shielding layer in the coaxial cable is used in a multiplex mode, the shielding layer is used for the purpose of shielding signals and meanwhile is further used in cooperation with the positive power line to serve as a power line, one negative power line is omitted compared with an existing combined cable, resources are fully used, and cost is saved.
Description
Technical field
The present invention relates to safety monitoring technical field of cables, refer more particularly to the assemble line cable structure improvement aspect of carrying out video signal transmission for connecting video camera and powering for video camera.
Background technology
Existingly carry out video signal transmission and the cable of powering for video camera has two kinds of structures for connecting video camera: the 1st kind is BNC video line and DC power wire combination; 2nd kind as shown in fig. 1, adopts a coaxial line 1 and positive and negative two power lines 2 to combinationally use.
The shortcoming of the 1st kind of combination cable existence is: main line is 3 very thin holding wires, is not 75 ohm line of standard, does not mate (CCTV is the supervisory control system of 75 ohm) with whole CCTV supervisory control system, there is decay large, can not be used for HD-SDI supervisory control system; Can use in CVI, TVI, AHD and novel C CTV system, but have interference, distance can not be grown and use.
The shortcoming of the 2nd kind of combination cable existence is: coaxial line 1 and power line 2 work alone, and there is the wasting of resources, consumptive material is many, and cost is high; Can only be used in HD-SDI and simulated monitoring system, as in CVI, TVI, AHD system, have interference when multichannel uses and produce.
Summary of the invention
In sum, the object of the invention is to solve when the existing coaxial line comprising screen uses with power wire combination and there is the wasting of resources, consumptive material is many, the technical deficiency that cost is high, and proposes a kind of multiplexing type being applied to safety monitoring and combine cable and connection thereof.
For solving technical problem proposed by the invention, the technical scheme adopted is: a kind of multiplexing type combination cable being applied to safety monitoring, described assemble line cable includes coaxial cable, it is characterized in that: also comprise a positive power line be fixedly connected with side by side with coaxial cable.
Described coaxial cable is also provided with a negative supply be electrically connected with described coaxial cable screen apart from 10 ~ 30cm place, end and goes between; Described coaxial cable end is connected with BNC connector; Described positive power line is connected positive terminal and the negative terminal of DC joint respectively with negative supply lead-in wire.
Described coaxial cable includes inner wire, isolated insulation layer, screen and serving from inside to outside successively; The insulating barrier that positive power line includes metal core and is located at outside metal core; Described serving is connected by dowel with between insulating barrier.
Described serving, insulating barrier and dowel are same material integrated formed structure.
A kind of multiplexing type combination cable connection being applied to safety monitoring, it is characterized in that described connection is: a coaxial cable and a positive power line are combined into one and combine cable, wherein coaxial cable is used as video signal transmission, is coordinated by the screen of coaxial cable be used as to power with positive power line.
Connect BNC connector in the end of described coaxial cable, the end of positive power line is connected with the positive terminal of a DC joint, and the negative terminal of DC joint is electrically connected with coaxial cable screen by a negative supply lead-in wire.
The length of described negative supply lead-in wire is: 10 ~ 30cm.
Beneficial effect of the present invention is: the present invention carries out multiplexing to the screen in coaxial cable, screen is except for except signal shielding purposes, also use with the use of as power line with positive power line simultaneously, relative to existing assemble line, save a negative power line, make full use of resource, provide cost savings, and there are 75 ohm that mate in CCTV system, noiseless generation in CVI, TVI, AHD system simultaneously, simulation, CVI, TVI, AHD, HD-SDI supervisory control system, i.e. joint use can be used in.
