Abstract
The utility model relates to a lightning protection and anti-interference telephone socket which is characterized in that a lightning protection circuit is arranged in a casing. A line inlet end of a telephone line is connected in parallel with a recoverable fuse and a varistor. The other end of the varistor is connected with the line inlet end of the telephone line and the recoverable fuse. The other end of the recoverable fuse is connected in parallel with an inductor and a gas discharge tube. The other end of the recoverable fuse is connected with an inductor and the other gas discharge tube, and two gas discharge tubes are connected with each other. The other end of the inductor is connected in parallel with one output end of the telephone and a transient killer tube sum capacitor which is connected in parallel with the other output ends of the inductor and the telephone. The utility model has the advantages that the telephone and other communication devices can be protected from lightning strike damage, and a high-frequency interference signal of the telephone line can be suppressed.
Description
The utility model relates to a kind of telephone socket, the anti-interference telephone socket of particularly a kind of lightning protection.
General telephone socket is not considered the lightning protection interference protection measure mostly at present, and telephone set subjects to be struck by lightning impaired, is disturbed and changing down when transfer of data.
The purpose of this utility model provides the anti-lightning strike jamproof phone Thunder preventing socket of a kind of energy.
The technical solution of the utility model is the anti-interference telephone socket of a kind of lightning protection of design, comprise housing, it is characterized in that: a lightning protection circuit is arranged in the housing, this circuit is by the telephone wire end of incoming cables, the upper end of end of incoming cables also connects one and can recover fuse and piezo-resistance, the answer the call lower end of line end of incoming cables and another of the piezo-resistance other end can recover fuse, the upper end can be recovered the other end of fuse and be connect a upper end inductance and a gas discharge tube, the lower end can be recovered the other end of fuse and be connect a lower end inductance and a gas discharge tube, the other end of two gas discharge tubes is connected, the other end extension telephone output of upper end inductance and the negative terminal and an electric capacity of transient state suppressing pipe, the anode of transient state suppressing pipe and the electric capacity other end and lower end inductance and the phone output other end also connect.
The utility model has the advantages that communication devices such as can protecting telephone set is not struck by lightning, suppress the high-frequency interferencing signal on the telephone line.
Below in conjunction with accompanying drawing the utility model is elaborated,
Accompanying drawing is a circuit theory schematic diagram of the present utility model,
Comprise among the figure lightning protection circuit is arranged in the housing, this circuit is by the telephone wire end of incoming cables, the upper end 1 of end of incoming cables also connects a upper end and can recover fuse 2 and piezo-resistance 3, fuse 5 can be recovered in answer the call lower end 4 and another lower end of line end of incoming cables of piezo-resistance 3 other ends, the upper end can be recovered the other end of fuse 2 and be connect a upper end inductance 6 and a gas discharge tube 7, the lower end can be recovered the other end of fuse 5 and be connect a lower end inductance 8 and a gas discharge tube 9, two gas discharge tubes 7,9 the other end is connected, the other end extension telephone output 10 of upper end inductance 6 and the negative terminal and an electric capacity 12 of transient state suppressing pipe 11, the anode of transient state suppressing pipe 11 and electric capacity 12 other ends and lower end inductance 8 and the phone output other end 13 also connect.When telephone wire is run into when having 220V voltage, fuse 2 can be recovered in the upper end, and the lower end can be recovered fuse 5 and can be cut off automatically, and only putting, personnel and equipment are injured, after thunderbolt takes place, at first short circuit of piezo-resistance 3, in order to avoid connect equipment after breaking, when lightning strike signals is big slightly, two gas discharge tubes 7,9 are with the lightning strike signals short circuit, as the signal that is struck by lightning is stronger, and transient state suppressing pipe 11 guarantees so that with the lightning strike signals short circuit external lightning strike signals does not damage communication devices such as telephone set.
