Abstract
Be applied to a multiplexing type combination cable for safety monitoring, relate 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.Solve existing comprise screen coaxial line and power wire combination there is the wasting of resources when using, consumptive material is many, the technical deficiency that cost is high, 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.Carry out multiplexing to the screen in coaxial cable, screen, except for except signal shielding purposes, also uses with the use of as power line with positive power line simultaneously, relative to existing assemble line, saves a negative power line, makes full use of resource, provide cost savings.
Description
Technical field
The utility model relates to safety monitoring technical field of cables, refers 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
As shown in fig. 1, existingly carry out video signal transmission and the combination cable of powering for video camera is generally that employing coaxial line 1 combinationally uses with positive and negative two power lines 2 for connecting video camera, coaxial line 1 and power line 2 work alone, and there is the wasting of resources, consumptive material is many, and cost is high.
Summary of the invention
In sum, the purpose of this utility model is to solve when the existing coaxial line comprising screen uses with power wire combination exists the wasting of resources, and 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.
For solving the technical problem that the utility model proposes, 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.
The beneficial effects of the utility model are: the utility model 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.
Accompanying drawing explanation
Fig. 1 is traditional combination cable cross section structure schematic diagram;
Fig. 2 is cross section structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and the preferred specific embodiment of the utility model, structure of the present utility model is further described.
With reference to shown in Fig. 2, the utility model includes coaxial cable 4 and positive power line 5; Described coaxial cable 4 includes inner wire 41, isolated insulation layer 42, screen 43 and serving 44 from inside to outside successively; Positive power line 5 includes metal core 51 and is located at the insulating barrier 52 outside metal core 51; Described serving 44 is connected by dowel 3 with between insulating barrier 52.Described serving 44, insulating barrier 52 and dowel 3 can be same material integrated formed structures.
Conveniently be connected with camera power supply interface and power, end of the present utility model is connected with negative supply lead-in wire, and one end of negative supply lead-in wire is electrically connected with the cable screen 43 of coaxial cable 4; Negative supply lead-in wire is preferably connected to apart from 10 ~ 30cm place, coaxial cable 4 end.Described coaxial cable 4 end is connected with BNC connector, by BNC connector can easily with the grafting of camera video output interface; Described positive power line 5 end and the other end that negative supply goes between are connected positive terminal and the negative terminal of DC joint respectively, the convenient and camera power supply input interface grafting by DC joint.
