Embodiment Construction

[0026] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. As mentioned above, the present invention provides a high-sensitivity non-contact line-hunting device and line-hunting method, which can reduce noise and improve line-hunting sensitivity, thereby improving work efficiency and anti-interference ability of the detection device, and reducing detection work intensity .

[0027] Figure 1 to Figure 5 An embodiment of a high-sensitivity non-contact line-finding device of the present invention is shown. Please refer to figure 1 , the high-sensitivity contactless line hunting device 10 includes a transmitter 100 and a receiver 200 . The transmitter 100 is connected to the port of the target cable through a common interface, so that a surrounding signal field is generated around the loop of the target cable, and the receiver 200 uses its probe to identify the transmitter 100 alon...

Abstract

The invention discloses a high-sensitivity non-contact line haunting device comprising a transmitter and a receiver. The transmitter comprises a generating circuit, a frequency dividing circuit and an amplifying circuit; the master frequency signal generated by the generating circuit is subjected to the frequency dividing by the frequency dividing circuit and is formed into the divided-frequency signal, and then the divided-frequency signal is amplified into the amplified signal by the amplifying circuit; the amplifying circuit is connected with a lead and is used for transmitting the amplified signal through the lead; the receiver comprises a receiving circuit, a frequency-selecting amplifying circuit and a complex frequency dividing circuit; the receiving circuit comprises a carbon rod coil and is used for receiving the amplified signal and delivering the received amplified signal to the frequency-selecting amplifying circuit for further amplification and to the complex frequency dividing circuit for frequency dividing; and the output end of the complex frequency dividing circuit is connected with an indicator. The high-sensitivity non-contact line haunting device is more sensitive and can reduce the noise, improve the work efficiency and the anti-interference capacity of a detecting device and lower the detection intensity. The invention also discloses a high-sensitivity non-contact line haunting method.

Description

technical field [0001] The invention relates to a circuit testing instrument, more specifically to a high-sensitivity non-contact line-finding device for communication and computer networks. Background technique [0002] With the rapid development of the network and communication industry, the communication and network capacity has increased geometrically, and the difficulty of wiring has further increased. The cable finder has become an essential tool for finding cables during the construction and daily maintenance of various metal lines such as network cables and communication cables. It can quickly and efficiently find the required cable from a large number of wire harness cables. [0003] At present, there are two kinds of known wire finders: one is a contact type: a metal probe is used to directly contact the metal part of the wire core, and then combined with a multimeter to judge. This method needs to peel off the insulation sheath of the metal wire, which is less u...
