Abstract
Disclosed is a quick search electroprobe for breakage of telephone wires. An electroprobe power source is mounted in an inner cavity of the front end of the electroprobe, the front end of the electroprobe light source is connected with an electroprobe rod and a metal probe respectively, a transmission line, a circuit board, a circuit sensor, a telephone wire breakage display, a switch, a telephone wire normal-state display and circuits are arranged at the rear end of the electroprobe light source and are connected one another, three triode transistors are connected with the telephone wire breakage display and the telephone wire normal-state display respectively, one ends of the triode transistors are connected with the electroprobe light source, and the other ends of the triode transistors are docked with the circuit sensor. A battery is arranged on one side of the triode transistors and fixed on the upper side of the electroprobe by a plug cover.
Description
Technical field
The present invention relates to a kind of fast finding electroprobe, particularly a kind of telephone wire broken string fast finding electroprobe, belongs to maintenance electroprobe technical field.
Background technology
In telephone wire disconnection fault process, often can run into the situation of circuit breaking, generally searching circuit, to form power-off be wherein cumbersome thing, especially when circuit more complicated, circuit have insulating coating; At present, the main tool of searching circuit breaking adopts universal electric meter, due to universal electric meter costly, amateur department or personnel are not generally equipped with, and meanwhile, also more professional when universal electric meter uses, general librarian use usually has the sensation of inconvenience; In addition, multimeter is merely able to judge whether whole circuit breaks, but, but can not give clear and definite judgement as breaking wherein, so, existing multimeter also exist complex structure, detection time long, power-off accurate location cannot be judged, use trouble, defect that accuracy of detection is low.
Summary of the invention
The object of the invention is to: provide a kind of structure simple, detect rapidly, detect and judge that broken position is accurate, convenient and swift, accuracy of detection is high, the time of searching is short a kind of telephone wire breaks fast finding electroprobe, overcomes the above-mentioned defect existing for existing lookup tool.
The technical solution adopted for the present invention to solve the technical problems is: a kind of telephone wire broken string fast finding electroprobe, it is made up of metal probe pen head, electroprobe bar, electroprobe body, electroprobe light source, transmission line, wiring board, line sensor, electric wire broken string display, switch, electric wire normal displays, transistor, battery, blanking cover, described outage detection electroprobe is provided with an electroprobe light source in the inner chamber of electroprobe body front end, is connected to electroprobe bar and metal probe pen head in the front end of electroprobe light source; Be respectively arranged with transmission line, wiring board, line sensor, electric wire broken string display, switch, electric wire normal displays in the rear end of electroprobe light source, circuit is also interconnected; Wherein on electric wire broken string display and electric wire normal displays, be connected to three transistors, three transistor one end are connected with electroprobe light source, and one end and line sensor connect in addition; In the side of transistor, be provided with a battery, battery is fixed on above electroprobe body by blanking cover.
Beneficial effect of the present invention: owing to present invention employs such scheme, when line interrupted is broken down, only need by electroprobe probe along the route of line alignment through out-of-date, if the route of process be have curtage, then curtage will give off magnetic field, magnetic field will produce electromagnetic induction signal to electroprobe probe, this electromagnetic induction signal is formed after amplifying circuit amplification through three transistors, light source is made to send light, electricity normal display screen display energising is normal, when electroprobe probe crosses disconnecting place, owing to there is no corresponding voltage or electric current, so, light source just transfers non-light emitting state to from luminance, power-off display screen display energising is abnormal, the accurate location of electroprobe probe and lockable power-off, same reason, if transfer luminance to from non-light emitting state, can judge herein as disconnecting place equally, so, it is simple that the present invention has structure, detect rapidly, detect and judge that broken position is accurate, easy to use, the advantage that accuracy of detection is high, effectively overcome the complex structure existing for existing multimeter, detection time is long, the accurate location that breaks cannot be judged, use trouble, the defect that accuracy of detection is low.
