1 is also connected in series with resistance 4 and battery pack 5.
Preferably, described diode 3 adopts resistance identical diode.
Advantage of the present utility model and good effect are：
1st, the utility model has been played in the more project of cable quickly, accurately and reliably act on, time saving and energy saving, originally
Need the line inspection work that many people coordinate, it is only necessary to which a people can complete.
Description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
In figure：1st, terminal block；2nd, wiring hole；3rd, diode；4th, resistance；5th, battery pack.
Specific embodiment
The utility model embodiment is further described below in conjunction with accompanying drawing：
As shown in figure 1, a kind of diode testing device, including terminal block 1, the terminal block 1 is fixed on one piece of insulation board,
The terminal block 1 is connected at least three wiring holes 2 below, and the terminal block 1 is connected at least two diodes 3 above, and adjacent two
The identical Series connection welding of 3 polarity of individual diode in terminal block 1, below a correspondence diode above between any two wiring hole 2
3, the terminal block 1 is also connected in series with resistance 4 and battery pack 5.Described diode 3 adopts resistance identical diode.
The characteristics of the utility model mainly utilizes diode forward tube voltage drop makes.
As shown in figure 1, concrete manufacturing process, is fixed to a terminal block 1 on one piece of insulation board, the terminal block first
Seven wiring holes 2 are connected under 1, and the terminal block 1 is connected to six 2CP12 diodes 3, and two neighboring 2CP12 diodes 3 above
In terminal block 1, six 2CP12 diodes 3 pass through the current-limiting resistance 4 of one 250 Ω of series connection to the identical Series connection welding of polarity
It is connected in 4.5V battery packs 5, seven corresponding positions of wiring hole 2 are followed successively by a, b, c, d, e, f, g point from left to right, thus
One group of stage voltage is formed for a points in b, c, d, e, f, g point, and we are connected on cable to be checked respectively a, b, c, d, e, f, g
On seven heart yearns of one end, then just easily measure this group of stepped-up voltage in the other end of cable to be checked, according to voltage
Size, it is possible to accurately determine the numbering of seven heart yearns.
If there is a heart yearn recognize in seven cores cable to be checked, the corresponding wiring hole 2 of a points is connected to, that is, is set to 1
Number heart yearn, other six roots of sensation heart yearns are arbitrarily connected on remaining wiring hole 2, it is possible to which the other end to cable to be checked removes measurement electricity
Pressure.It is No. 2 heart yearn if measuring 0.63V, it is exactly other five to measure 1.26V, 1.69V ... 3.78V by that analogy respectively
The numbering of heart yearn.In the measurements if it find that the voltage of two heart yearns is the same, such as the 3rd line is so known that for 1.26V
With the short circuit of other line, exclusion is should give.If heart yearn there is no voltage to Line 1, then determine that the open circuit of this heart yearn.
If cable core to be checked is without any mark, can arbitrarily connect cable one end to be checked heart yearn to diode testing device
Terminal block lower end wiring hole on, then remove the cable other end to be checked, fix a certain heart yearn with the red pen of digital multimeter, with
The black pen of universal meter is surveyed and the magnitude of voltage between other heart yearns respectively, wherein has magnitude of voltage and one group of maximum line of numerical value, can
To be defined as Line 1, a points are positioned.Then other b, c, d, e, f, g points are measured by voltage ascending order successively based on a points, electricity
The numbering of core can just be completed.
Described diode is further connected with concatenation line；Described concatenation line series connection is connected to prolongation structure；Described prolongation structure
Including being welded with expansion wiring hole and expanding the expansion terminal block of diode, the both sides of the expansion terminal block are connected to concatenation line,
When the wiring hole failure of original diode testing device, can be connected by concatenating line, using the expansion wiring hole of prolongation structure
Substituted；Or original diode testing device wiring number of perforations it is inadequate when, by concatenate line be connected, using prolongation structure
Expanding wiring hole carries out increase-volume.
Digital multimeter is preferably used in measurement voltage course, and input resistance is high, and the loss of voltage is little, can also be easily
Distinguish polarity of voltage.
Described diode adopts resistance identical diode, is easy to the quickly and accurately line inspection.
The utility model has been played in the more project of cable quickly, accurately and reliably act on, time saving and energy saving, is originally needed
Want the line inspection work that many people coordinate, it is only necessary to which a people can complete.
It is emphasized that embodiment described in the utility model is illustrative, rather than it is determinate, therefore this reality
With the new embodiment being not limited to described in specific embodiment, it is every by those skilled in the art according to of the present utility model
The other embodiment that technical scheme draws, also belongs to the scope of the utility model protection.
