Summary of the invention
The utility model is to insert big, the unsettled defective of data of loss in order to overcome existing communication signal lighting protection electricity, surge protector, and provide a kind of simple in structure, insert loss little, make stable signal transmission and in same housing, realize the anti-thunder and lightning of signal of communication, the surge protector of two pairs of signal circuits of protection
The technical measures that the utility model is taked are: signal of communication is prevented thunder and lightning, surge protector, comprise a fire retardant insulating plastic casing, be located at housing bottom base, be located at the housing both sides a plurality of supports, be located at signal terminal on each support and be located at lightning protection circuit in the housing; Be characterized in, comprise that also one is located at the total earth terminal on the base; Described lightning protection circuit comprises and two protection loops that are connected with two pairs of holding wires respectively that each protection loop comprises that the resistance inductance parallel circuits, that is serially connected in respectively on a pair of signal transmssion line is connected this gas discharge tube between input of signal transmssion line, one is connected this to the Transient Voltage Suppressor between the output of signal transmssion line; Two gas discharge tubes in described two protection loops are by total earth terminal ground connection.
Above-mentioned signal of communication is prevented thunder and lightning, surge protector, and wherein, the resistance in described each resistance inductance parallel circuits and the span of inductance are respectively: resistance is that 0.1 Ω～100 Ω, inductance are 0.1 μ H～1mH.
Above-mentioned signal of communication is prevented thunder and lightning, surge protector; wherein, described binding post has two pairs * 2 groups, wherein every group two centerings; a pair of for connecting input, the output wiring terminal of protection loop one holding wire, another is to input, output wiring terminal for another holding wire of connection protection loop.
Because the utility model has adopted above technical scheme, when Lightning Electromagnetic Pulse entering signal line, make Transient Voltage Suppressor TVS start in time at 1nS, prevention is because of the sudden change corrupt data communication equipment of thunderbolt energy, increase the transmission data stability, reach the purpose of having protected electronic information communication equipment; And,, help the integrality of communication signal because the effect of the stopping direct current of inductance, logical interchange reduces the amplitude loss of transmission signals owing to be connected in series resistance inductance parallel circuits in the line.Because a protector can be protected two pairs of signal circuits simultaneously, installation volume is dwindled greatly again.
