Brief description
Fig. 1 is the structural representation of conducting wire to be measured；
Fig. 2 is the structural representation of testing circuit.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in more detail.
As shown in Figure 1, some conducting wires are arranged side by side, if the testing circuit in the present embodiment is used for being arranged side by side
Dry bar conducting wire is detected.
As shown in Figure 2, the testing circuit in the present embodiment includes one first detection part of path and several second detection lines
Section, first detection part of path and several second detection part of paths be arranged in parallel, first detection part of path and several second
One end of detection part of path is all electrically connected with positive source, and the first detection part of path is another with several the second detection part of paths
End is all electrically connected with power cathode, and on the first detection part of path and several the second detection part of paths, all concatenations are provided with an instruction
It is provided with two junction points (junction point a and junction points on lamp, the first detection part of path and several the second detection part of paths
B), all open a way between two junction points on the first detection part of path and several the second detection part of paths；
On several the second detection part of paths, all concatenations are provided with a switch.
Preferably, all concatenations are provided with an electricity on the first described detection part of path and several the second detection part of paths
Resistance.So, when the first detection part of path and the second detection part of path switch on power, resistance is permissible
The present embodiment also discloses a kind of detection method, and described detection method is used for some conductions being arranged side by side
Circuit is detected, described detection method includes:
(1), during original state, the switch on several the second detection part of paths all disconnects, by some conducting wires one
One corresponding be connected on the first detection part of path and several the second detection part of paths, the two ends of conducting wire respectively with right
Two junction point electrical connections on the first detection part of path answered or the second detection part of path；
(2) if the display lamp on the first detection part of path does not work, judge to be connected to leading on the first detection part of path
Electric line open circuit or shorted to earth；If the display lamp on the first detection part of path is bright, and on certain second detection part of path
Display lamp is bright, then judge the conducting wire that is connected on the first detection part of path with the second detection part of path that is connected to this on leading
The mutual short circuit of electric line；If the display lamp on the first detection part of path is bright, and the instruction on several the second detection part of paths
Lamp does not all work, then judge that the conducting wire being connected on the first detection part of path is normal；
One by one by second detect part of path on switch closure, when by certain second detection part of path on switch closure
When, if the display lamp on this second detection part of path does not work, judge to connect the conducting wire on this second detection part of path
Open circuit or shorted to earth；If this second detection part of path on display lamp bright, and in addition certain second detection part of path on
Display lamp is bright, then judge the mutual short circuit of conducting wire being connected on this two second detection part of paths；If this second detection
Display lamp on part of path is bright, and the display lamp on other the second detection part of paths does not all work, then judge to be connected to this second inspection
Conducting wire on survey line section is normal.
It is provided with a resistance due to all concatenating on the first detection part of path and several the second detection part of paths, so, when
Have conducting wire over the ground short circuit when, resistance can prevent power supply to be burned.
Below only explanation is made that with regard to this utility model application preferably example, but is not to be construed as to claim
Limit, structure of the present utility model can have other changes, is not limited to said structure.In a word, all of the present utility model solely
The various change made in vertical scope of the claims is all in protection domain of the present utility model.
