Detailed description of the invention
Fig. 1 is the structure chart of a specific embodiment of the verifying unit of the multi-core cable wire of the utility model；
Fig. 2 is the internal circuit diagram of the verifying unit of multi-core cable wire in a specific embodiment of the utility model.
Specific embodiment
To enable the above and other objects, features and advantages of the utility model to be clearer and more comprehensible, it is cited below particularly out preferably
Embodiment, and cooperate shown in attached drawing, it is described in detail below.
As shown in FIG. 1, FIG. 1 is the structure charts of the verifying unit of the multi-core cable wire of the utility model.The multi-core cable wire
Verifying unit be made of common line crimping end 1, fixed value resistance rapid presser thread end 2, shell 3 and crimping mouth 5.
Common line crimping end 1 is connected to one end of public connecting line, and the other end of the public connecting line is connected to multimeter,
Diode is inscribed in common line crimping end 1, using its individual event electric conductivity, is reversely not turned on subsequent resistance.
Fixed value resistance rapid presser thread end 2 has multiple pressure line terminals, to be connected to the multiple of cable to be detected
One end of the end of a thread, the other end of the multiple the end of a thread are connected to multimeter, fixed value resistance rapid presser thread end 2 is inscribed be sequentially connected in series it is more
The resistance of a 1K Ω, the multiple resistance and Diode series.In one embodiment, as shown in Fig. 2, fixed value resistance rapid presser thread
21 1K Ω resistance being sequentially connected in series are inscribed in end 2, diode D are placed in head end, using its individual event electric conductivity, with subsequent electricity
Resistance is reversely not turned on；Thereafter it is sequentially connected in series the resistance of 21 1K Ω, the characteristic successively increased using resistance value after resistor coupled in parallel, each
Terminal increases the resistance value of 1K Ω, and the pressure line terminal connect by resistance each in this way has different resistance values, for example No. 1 pressure line terminal
Resistance value be exactly the resistance values of 1K ohm, No. 15 pressure line terminals be exactly that the resistance values of 15K ohm, No. 21 pressure line terminals is exactly
21K ohm；The different resistance value of line segment is just imparted after connecting upper route on pressure line terminal, in this way in the other end of line segment with ten thousand
Corresponding line segment can be measured with table.
Shell 3 covers on the outside of the verifying unit of the multi-core cable wire, to protect internal circuit.Corresponding on shell 3
Terminal position put on each terminal resistance value and eye-catching diode mark, in order to know every line assign resistance value.
Crimping mouth 5 is located at the outside at fixed value resistance rapid presser thread end 2, with fixation cable to be detected.
When in use, the end of a thread of cable one end of broken string is peeled off for the verifying unit of the multi-core cable wire of the utility model,
By with being crimped on each terminal, thus having given the different resistance value of every route.Then the other end for arriving cable uses ten thousand
It is measured with table, multimeter is got into the connecting line that the unilateral conduction on Ω shelves using diode finds out common terminal, to make
For common line use, then be connected with this root common line with the black test pencil line of multimeter, red test pencil line and other cables by
Root connection, and read on multimeter, when the resistance value shown on multimeter is 1K Ω, illustrate that this root line is exactly route 1, shows 2K
When Ω, illustrate that this root line is exactly route 2, when showing 20K Ω, illustrates to be exactly route 20, be carried out on the route measured at every
Label, each cable can offer a clear explanation in this way.
