Description
Technical field
The present invention relates to a kind of power-off and search electroprobe, particularly electroprobe is searched in a kind of wiring board power-off, belongs to maintenance electroprobe technical field.
Background technology
In electrical maintenance and installation process, often can run into the situation of circuit disconnecting, generally searching circuit, to form disconnecting be wherein cumbersome thing, especially when circuit more complicated, circuit have insulating coating; At present, the main tool of searching circuit disconnecting 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 the whether disconnecting of whole circuit, but, but can not give clear and definite judgement, so existing multimeter also exists the defect that clearly can not detect judgement to broken string place as disconnecting wherein.
Summary of the invention
The object of the invention is to: provide a kind of structure simple, search rapidly, a kind of wiring board power-off of searching de-energized accurate, convenient to use searches 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: electroprobe is searched in a kind of wiring board power-off, it is made up of electroprobe probe, electroprobe bar, electroprobe body, transmission line, electroprobe light source, wiring board, circuit normal displays, wiring board power-off display, electroprobe switch, line electrode sensor, transistor, battery, blanking cover, described power-off is searched electroprobe in the inner chamber of electroprobe body front end, is provided with an electroprobe light source, is connected to transmission line, electroprobe bar and electroprobe pops one's head in the side of electroprobe light source; Wiring board, circuit normal displays, wiring board power-off display, electroprobe switch and line electrode sensor is respectively arranged with and mutual connection at the opposite side of electroprobe light source; Wherein on wiring board power-off display, circuit normal displays and line electrode sensor, be connected to three transistors, three transistor one end are connected with electroprobe light source, and one end is connected with wiring board in addition; In the side of transistor, be provided with a battery, battery is fixed by blanking cover.
Beneficial effect of the present invention: owing to present invention employs such scheme, when 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 metal probe, this electromagnetic induction signal is formed after amplifying circuit amplification through three transistors, light source is made to send light, electric wire regular link display screen occurs that normal netting twine shows, 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, electric wire broken string display screen then shows the display of abnormal netting twine, 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 accurately, conveniently advantage, effectively overcome the defect that clearly can not detect judgement to broken string place existing for existing multimeter.
