The cable connecting terminal that the utility model is convenient to plug and unplug by use and cable checking terminal, between the two, adopt two LED designs school line circuits that tube voltage drop is different, make when same cable connection, two different light emitting diodes of tube voltage drop become and are connected in parallel, thereby make light emitting diode both end voltage that tube voltage drop is large lower than trigger voltage, and the little light emitting diode both end voltage of tube voltage drop is not less than its trigger voltage, and then two lumination of light emitting diode states are changed, make operating personnel can be fast, accurately, efficient school line.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is circuit diagram of the present utility model.
Embodiment
An instrument, comprises housing 302 as shown in Figure 1, on described housing 302, is provided with handle 301.One side of housing 302 is provided with a plurality of cable connecting terminals 1,2 ... N, opposite side is provided with a plurality of cable checking terminals 11,12^1N, and described cable connecting terminal is corresponding one by one with cable checking terminal, is 1 correspondence 11,2 correspondences 12 ..., the corresponding 1N of N.Every group is mutually provided with school line circuit between corresponding cable connecting terminal and cable checking terminal, and because school line circuit structure, principle are identical, below to take school line circuit between the cable connecting terminal 1 cable checking terminal 11 corresponding with it be example explanation:
As shown in Figure 2, between the described cable connecting terminal 1 cable checking terminal 11 corresponding with it, school line circuit comprises the first light emitting diode D1, the second light emitting diode D11, resistance R 1, power switch K and power supply, the positive pole of the first described light emitting diode D1 connects the positive pole of power supply by power switch K, the negative pole of the first light emitting diode D1 connects the negative pole of power supply by resistance R 1, the positive pole of the first described light emitting diode D1 is gone back stube cable connection terminal 1, the negative pole of the first light emitting diode D1 connects the negative pole of the second light emitting diode D11, the anodal stube cable school line terminals 11 of the second light emitting diode D11, the tube voltage drop of the first described light emitting diode D1 is greater than the tube voltage drop of the second light emitting diode D11.The first light emitting diode described in the present embodiment is green LED, and its voltage is reduced to 3.0V ~ 3.2V.The second described light emitting diode is that its voltage of red light emitting diodes is reduced to 2.0V ~ 2.2V.
The principle of school described in the utility model line circuit is: when turning on the power switch K, due to the first light emitting diode forward conduction, green light, represents that instrument normally uses, cable under test.When the one end at the interior insertion cable of cable connecting terminal 1, during the other end of the interior insertion cable of cable checking terminal 11, due to cable conducting effect, the first light emitting diode D1 and the second light emitting diode D11 are the relation of being connected in parallel, and because the dividing potential drop at light emitting diode two ends after parallel connection reduces, so the first luminous light emitting diode D1 is because tube voltage drop is extinguished greatly at the beginning, the second light emitting diode D11 is due to the little conducting of tube voltage drop, so staff can observe directly the bright phenomenon of going out, show that the cable between cable connecting terminal 1 and cable checking terminal 11 is same cable.The principle of the school line circuit between other terminal is equally not repeated.
During actual school line, turn on the power switch K, if find the first light emitting diode D1, the second light emitting diode D11 ... all luminous, show that instrument can normally use (if having not luminous, show that Na Yi road, for damaging, does not re-use this road during the line of school). Cable connecting terminal 1,2 is inserted respectively in one end of many cables to be measured ... N, and then manually by the take other end of cable to be measured of root, insert successively cable checking terminal 11,12^1N, if find the above-mentioned one bright phenomenon of going out, show that now two cables to be measured are same, after mark, can carry out next root detection.
Every group described in the utility model is mutually horizontal direction corresponding setting one by one between corresponding cable connecting terminal and cable checking terminal jacks, the operating personnel's observed and recorded of being more convenient for; Described cable connecting terminal and cable checking terminal are cable insert row, the plugging and unplugging of the cable of being more convenient for like this.
