One end is connected with pedestal, and multiple anode contacts are that the center of circle surround distribution using positive terminal.Make transient current when thunder and lightning hits power transmission line
Rapidly increase, electric current flows to fuse along metal column, and fuse crosses the insurance that fuses conference produces huge heat because of electric current at this time
Silk, disconnects circuit, so as to play anti-lightning strike effect.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model mobile phone signal amplifier；
Fig. 2 is the sectional drawing of the utility model mobile phone signal amplifier；
Fig. 3 is the utility model mobile phone signal amplifier A areas enlarged drawing.
Embodiment
The utility model is further elaborated and illustrated with reference to specific embodiment and Figure of description：It refer to figure
1 and Fig. 2, a kind of mobile phone signal amplifier, including mainboard 10, housing 20, input port 31, delivery outlet 32 and power interface.
Mainboard 10 is wrapped in inside housing 20, and input port 31, delivery outlet 32 and power interface both pass through housing 20 and mainboard
10 connections.
Please refer to Fig.3, power interface includes pedestal 41, positive terminal 42 and a plurality of anode contact 43.Pedestal 41 and mainboard 10
It is electrically connected.
Positive terminal 42 includes insulation sleeve 421, metal column 422 and fuse 423, and 421 one end of insulation sleeve is connected with pedestal 41,
421 other end coated metal column of insulation sleeve, 422 one end, forms with cylinder.421 inner surface of insulation sleeve is equipped with ceramic inner walls 50, protects
Dangerous silk 423 passes through the insulation sleeve 421 equipped with ceramic inner walls 50, and 423 both ends of fuse connect pedestal 41 respectively and insulation sleeve 421 wraps
422 one end of metal column is wrapped up in, forms a path.
A plurality of 43 one end of anode contact is connected with pedestal 41, and a plurality of anode contact 43 is surround with positive terminal 42 for the center of circle to be divided
Cloth, and a plurality of anode contact 43 is equipped with protrusion 431 away from pedestal one end side wall, protrusion 431 is directed to positive terminal 42.
Transient current is set rapidly to increase when thunder and lightning hits power transmission line, electric current flows to fuse 423 along metal column 422, at this time
