Abstract
The utility model relates to a cable for transmitting telephone and television data to subscribers, which integrally transmits the data of a television and a telephone. A cable is provided with a radio-frequency conductor and an acoustic-frequency conductor which are mutually insulated; therefore, two sets of networks are replaced by one cable. The transmission quality of the telephone data is ensured, and simultaneously, the transmission quality of television signals is improved; the utility model avoids the overlapping investment and overlapping construction of countries, enterprises and individuals, and the raw materials and the funds are saved. The utility model has positive meanings for quickening the starting of the television and telephone market of villages and improving the popularization rate of broadcast televisions and telephones. The utility model has the advantages of easy fabrication, low cost and good performance and is a practical and ideal cable product.
Description
The utility model relates to the basic components and parts of electricity, particularly a kind of cable that belongs to TV, telephone transmission network.
At present, TV, the telephone transmission network of China establish one's own system basically, and overlapping investment such as electric pole, cable, repeated construction cause the waste of national raw material, fund, form network simultaneously in the city disorderly as spider web; Take up an area of road occupying in the rural area, have a strong impact on and be unfavorable for traffic safety.Although it is the stored-program control exchange that has has been developed the CATV function, still unresolved with can transmitting television signals take on the telephone the again problem at family of same cable.If the laying information superhighway accomplishes that Fiber to the home, realize the transmission of voice, data, image " Trinity ", then need sizable investment, this is unpractical concerning vast rural area and small and medium-sized cities at present.
The purpose of this utility model is to take into account the specification requirement of TV, phone transmission, develop a kind of can be on same cable the speech reading service cable of TV transmission, phone simultaneously.
The purpose of this utility model solves by following technical solution:
A kind of speech reading service cable outwards is made up of cable core, coupling core insulation layer, separator, netted shielding layer, oversheath successively from the lining, is provided with radio frequency conductor insulated from each other, audio frequency conductor at coupling core insulation layer center; Its center is the radio frequency conductor of a tape insulation sheath, is provided with the audio frequency conductor of two pairs of tape insulation sheaths all around, and these two pairs of audio frequency conductors are the diagonal angle and distribute.
This speech reading service cable collection TV transmission, phone, data are one, accomplish not disturb mutually, when guaranteeing phone and data transmission quality, have improved the TV signal transmission quality, have improved stability and reliability; But the utility model and speech reading main cable in the city, the rural area flexible networking, replace two cover networks by cable, avoided country, enterprise, individual overlapping investment, repeated construction, saved raw material and fund, also made things convenient for the maintenance and management of network; Open up the rural market to accelerating, the popularity rate that improves radio and television and phone has positive meaning, be a kind of easily manufactured, cost is low, performance good and practical ideal replacement cable product.
Fig. 1 is the utility model structural representation;
Fig. 2 is a cutaway view of the present utility model.
According to accompanying drawing the utility model is further described below.
As shown in Figure 1, 2, a kind of speech reading service cable, form cable core by radio frequency conductor insulated from each other, audio frequency conductor, outside radio frequency conductor 8, be provided with insulating sleeve 7, there are two pairs around the radio frequency conductor 8 and are the audio frequency conductor 5 that the diagonal angle distributes, respectively surround insulating sleeve 6 outside it, the space between radio frequency conductor and the audio frequency conductor is a polyethylene inserts 9, surrounds poly coupling core insulation layer 4, the aluminium pool netted shielding layer 2 of separator 3 copper wires and polyethylene oversheath 1 outside this cable core successively.In use, the speech reading service cable is five cores, and each household can connect a telephone set, a computer, multiple TV set, the specification of used cable, capacity are identical with the ordinary audio cable, its price is not higher than the price of existing cable, and its view reception effect reaches similar fiber-to-the-home effect.
