Utility model content
Technical problem to be solved in the utility model is to provide a kind of signal receiving device of line finder, having solved cable can exist various undesired signals to cause severe jamming to the signal receiving device of line finder around, also there is the weak phenomenon of signal in the signal receiving device of existing line finder simultaneously, cause the signal receiving device of line finder can not accurately reflect the problem of the position of target cable, the utlity model has strong interference immunity, the feature that signal intensity is large.
To this, the utility model provides a kind of signal receiving device of line finder, comprising: signal receiving module, comprises an outstanding detecting head in tip that is arranged at the signal receiving device top of described line finder, for receiving the voice signal of tested cord loop; Frequency selection circuit module, is connected with described signal receiving module, for the interference component of filtering sound signal; Amplifying circuit module, is connected with described frequency selection circuit module, for filtered voice signal is amplified; Receive indicating module, be connected with described amplifying circuit module, be used to indicate the voice signal amplifying through described amplifying circuit module; Receive power module, be connected with described signal receiving module, for power supply being provided to described modules.
Preferably, described amplifying circuit module comprises one stage signal amplifying unit, is connected with described frequency selection circuit module, for voice signal is amplified, with second signal amplifying unit, be connected with described one stage signal amplifying unit, for voice signal is further amplified.
Preferably, described reception indicating module adopts LED light emitting diode, hummer or earphone.
Adopt technique scheme, the detecting head of described signal receiving module, be arranged to most advanced and sophisticated outstanding shape, contribute to the voice signal detecting to be gathered on a point, voice signal intensity is superimposed upon on a point, contributes to strengthen receiving the intensity of signal, then pass through the interference component in described frequency selection circuit module filtering sound signal, through two-stage amplifying circuit, voice signal is amplified, last described reception indicating module indicates testing result again.The working site existing at a large amount of cables, the signal receiving device of described line finder is pointed to tested cable, if the signal receiving device of described line finder sends that buzzerphone, LED light emitting diode are lighted or earphone is sounded signal, tested cable is target cable.
Through repeatedly facts have proved, the signal receiving device of the line finder that employing frequency selection circuit module and amplifying circuit module combine, has significant interference free performance, has also effectively overcome the weak problem of detection signal simultaneously.
Compared with prior art, the utility model has the advantage of, the utlity model has strong interference immunity, signal intensity is large, the sound signal of output feature clearly.
