Abstract
The utility model relates to an LED line testing device independently operated by single person. The host machine of the utility model comprises a power supply, a switch, a plurality of diodes which are connected in series and are connected with the positive pole of the power supply, and a plurality of connecting terminals which are communicated with the negative poles of the diodes, and both ends of the switch are connected in papallel with auxiliary display circuits which are formed by the connection of a limiting resistor and an LED in series; the auxiliary machine comprises a plurality of light-emitting diodes whose positive poles are respectively connected with a connecting terminal, and after connecting together, the negative poles are connected with a potentiometer in series and then a scouting line is led out. The utility model is compact and portable and can be independently carried out the detection for line correcting, line testing, short circuit, broken circuit, and other items by single person, having a bright development prospect.
Description
The utility model relates to the correcting line machine of single independent operation, it belong to electric equipment, circuit or element carry out short circuit, open circuit, the proving installation of leakage or incorrect connection.
Traditional school line adopts instruments such as multimeter, school fire lamp, megger or telephone receiver, and needs usually by two people's compounding practices, take a lot of work many, work efficiency is low, demands improvement urgently.
The purpose of this utility model is a kind of simple in structure, easy to maintenance, small and exquisite and single correcting line machine of operating of design.
Technical essential of the present utility model can describe with reference to accompanying drawing.As shown in the figure, the LED correcting line machine of single independent operation contains the host A and the secondary machine B of separation, and described host A comprises power supply E and that join with the positive pole of power supply E, mutual diode in series D

N-2Negative electrode respectively with described connection terminal 3,4 ... N links to each other, light emitting diode and current-limiting resistance R
1Be connected in parallel on the two ends of described K switch after the series connection, link to each other with above-mentioned connection terminal 1 with the negative pole of above-mentioned power supply E respectively, above-mentioned connection terminal 2 then links to each other with the positive pole of above-mentioned power supply E; Described secondary machine B contains N light emitting diode and N connection terminal in parallel, and the anode of light emitting diode is continuous with corresponding connection terminal respectively, and the negative electrode of light emitting diode joins back series connection potentiometer R altogether
2Draw again and survey line M.
During the school line, can as shown in the figure the heart yearn among the cable under test C be joined with major and minor machine of the present utility model respectively, and supposition heart yearn numbering is identical with main frame connection terminal sequence number, all not luminous as LED in the wiring process, can confirm that cable does not have short trouble.K closes a switch after connecting, touch the connection terminal that is connected to heart yearn one by one with the detection line M on the secondary machine, until certain lumination of light emitting diode is arranged, then the heart yearn that links to each other with this tube anode promptly is No. 2 lines (communicating with No. 2 terminals and the positive source of host A), promptly is Line 1 (communicating with No. 1 terminal and the power cathode of host A) and survey heart yearn that line M touches this moment.At this moment, to survey line M is fixed on the secondary machine B1 line institute connecting terminal, and corresponding sign is pulled down and put to No. 2 lines from respective terminal, the LED that link to each other with this terminal this moment extinguishes, there is a light-emitting component luminous again on the secondary machine, what link to each other with this emissive element anode waits that looking into heart yearn promptly is No. 3 lines ..., single in this way working continuously can be rapidly and accurately to good line.
The utility model also can be used for supply socket and installs and detect, can disconnect building source box power supply this moment earlier, live wire, zero line and ground wire are connected with 1,2, No. 3 terminal of host A respectively, after closing a switch, arrive in each room with secondary machine B school line, its method of operating is the same, and gets final product wiring behind the intact line in school, not only soon but also accurate.
In addition, the utility model also can be used for the short circuit or the open circuit fault of detection line, both can detect with host A separately, also host A, secondary machine B can be used, and the result is very reliable.
