Abstract
The utility model relates to a cable television subscriber line, and particularly relates to a lightning protection environmental-friendly cable high-definition digital television subscriber line, which comprises a subscriber line body which is composed of a core wire and a shielding net, and a connector arranged at the tail end of the subscriber line body. The utility model is characterized in that the subscriber line body is divided into two sections, the core wires of the two sections of the line body are connected through two pins of a high-voltage capacitor electronic component, the shielding net in one section of the line body is surrounded and connected by a copper coil, the copper wire is connected with one pin of the high-voltage capacitor electronic component through a copper fixing clamp, and the shielding net of the other section of the subscriber line body is connected with the other pin of the high-voltage capacitor electronic component. According to the utility model, the core wire and the shielding net of the television subscriber line are both provided with the high-voltage capacitor electronic component. When voltage passing through the subscriber line is too high and exceeds the capacity of the capacitor, the capacitor is broken down and short circuit occurs, thereby effectively preventing damages imposed on a television and potential injuries for people by high voltage current.
Description
Technical field
The utility model relates to a kind of wired television subscriber line, particularly the wired digital TV in high resolution subscribers feeder of a kind of lightning protection environment-friendly type.
Background technology
In recent years, the particularly frequent appearance of Thunderstorm Weather of appearance along with exceedingly odious weather causes heavy losses to people's domestic electric appliance, particularly to the destruction of domestic television set.Because thunder and lightning passes to domestic television set by being arranged at outdoor wired television subscriber line easily, the final damage that causes domestic television set, and wired television subscriber line in the market all directly is connected with digital TV set-top box and directly is connected with television set, lightning protection device is not set, therefore exists potential safety hazard.
In order to address this problem, to invent a kind of simple in structurely, the wired digital TV in high resolution subscribers feeder of practical function lightning protection environment-friendly type just seems very meaningful.
Summary of the invention
The utility model provides a kind of simple in structure for the deficiencies in the prior art, the wired digital TV in high resolution subscribers feeder of practical function lightning protection environment-friendly type.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The wired digital TV in high resolution subscribers feeder of lightning protection environment-friendly type comprises heart yearn and gauze screen the subscribers feeder line body that consists of and the joint of being located at subscribers feeder line body end; Its design feature is that described subscribers feeder line body is divided into two sections, and the heart yearn between two sections line bodies is connected by high-voltage capacitance electronic component bipod; The described subscribers feeder line body wherein gauze screen in one section line body is surrounded by copper coil and connects, and copper cash is connected with a pin of high-voltage capacitance electronic component by copper geometrical clamp; Gauze screen in another section of subscribers feeder line body line body connects another pin of high-voltage capacitance electronic component.
The utility model lightning protection device has mainly used the puncture principle of high-voltage capacitance: heart yearn and gauze screen at wired digital TV in high resolution subscribers feeder have been installed respectively the high-voltage capacitance electronic component, when the overtension by subscribers feeder, the capacity that has exceeded electric capacity, electric capacity will open circuit in breakdown generation, thereby effectively stops high-tension current to the infringement of digital TV set-top box, television set and to personnel's potential injury.In addition because the capacitance structure of this utility model inside plays certain filter action when transmitting data information, Effective Raise information quality, realize that the high definition viewing needs.
Described geometrical clamp outside is provided with the injection moulding protective of bulge-structure, further strengthens the steadiness of connecting portion.
The shell of described subscribers feeder line body, injection moulding protective are environment-friendly polyvinyl chloride (PVC); Described joint material is environmental protection brass, and processes through the non-formaldehyde chemical plating nickel technology of environment-friendly type.Environment-friendly polyvinyl chloride (PVC) effectively prevents the wasting of resources and environmental pollution as the main raw material(s) of main this product, and copper nickel plating adopts the non-formaldehyde chemistry of environment-friendly type brass nickel-plating technology effectively to avoid environmental pollution and to the injury of human body.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Embodiment, the wired digital TV in high resolution subscribers feeder of lightning protection environment-friendly type as shown in Figure 1, is made of heart yearn 8 and gauze screen 6 the subscribers feeder line body 1 that consists of and joint 5 two parts of being located at subscribers feeder line body 1 end.
Subscribers feeder line body 1 is divided into two sections, and the heart yearn 8 of two sections line bodies is connected with high-voltage capacitance electronic component 9 bipods respectively; The subscribers feeder line body 1 wherein gauze screen 6 in one section line body is surrounded by copper cash 7 circles and connects, and copper cash 7 is connected with a pin of high-voltage capacitance electronic component 4 by copper geometrical clamp 3 again; Gauze screen 6 in subscribers feeder line body 1 another section line body connects another pin of high-voltage capacitance electronic component 4.By the way, can realize the purpose that heart yearn and gauze screen are connected by a high-voltage capacitance electronic component respectively, when the overtension by subscribers feeder, the capacity that has exceeded electric capacity, electric capacity will open circuit in breakdown generation, thereby effectively stops high-tension current to the infringement of digital TV set-top box, television set and to personnel's potential injury.
Geometrical clamp 3 outsides are provided with the injection moulding protective 2 of bulge-structure, adopt the injection moulding mode can play sealing, waterproof and dustproof effect, and more sturdy and durable.
The shell of subscribers feeder line body 1, injection moulding protective 2 are environment-friendly polyvinyl chloride PVC; Described joint 5 is processed for environmental protection brass and through the non-formaldehyde chemical plating nickel technology of environment-friendly type.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
