Below with reference to accompanying drawing, the utility model will be further described, it is necessary to which explanation, the present embodiment is with this skill
Premised on art scheme, detailed embodiment and specific operating process are given, but the scope of protection of the utility model is not
It is limited to the present embodiment.
Fig. 1 is a kind of structure chart of cable core detection means of embodiment of the present utility model, as shown in figure 1, this practicality
New structure, including cable to be detected 1, the first core 11 to be detected whether turned on and public affairs are enclosed with cable 1 to be detected
Conllinear core 10, the utility model also include being used for the first indicator lamp 2 and direct current supply electricity for indicating the testing result of the first core 11
Source 4, wherein DC power supply 4 are dry cell, and one end of the first indicator lamp 2 is connected with the positive pole of DC power supply 4, first
The other end of indicator lamp 2 is connected by public core 10 with one end of the first core 11, the other end and direct current of the first core 11
The negative pole of power supply 4 is connected, by setting DC power supply 4, the first indicator lamp 2 and public core 10 and to be detected first
Core 11 formed loop, it is simple in construction, can cable 1 efficiently to be detected whether turn on.Also parcel removes First Line in cable 1 to be detected
The second core 12 beyond core 11, i.e. the first core 11 are the core to be detected whether turned in cable, and the second core 12 is electricity
Other cores in cable in addition to core to be detected, the second core 12 and for indicating between the first core 11 and the second core 12
Whether one end of the second indicator lamp 3 of short circuit is connected, and the another of the second indicator lamp 3 terminates at the first indicator lamp 2 and direct current supply
Between the positive pole of power supply 4, power switch is also serially connected between the positive pole of the second indicator lamp 3 and the positive pole of DC power supply 4, together
When be connected by the second indicator lamp 3 with the second core 12 in cable, and be connected among loop, to be detected whether lead can be detected simultaneously
It is whether short-circuit between other cores in logical core and cable, so as to improve the degree of accuracy of cable detection result.If electricity to be detected
Screen layer and steel armour are provided with cable 1, the one end of screen layer and steel armour with the second indicator lamp 3 is connected, the second indicator lamp 3 it is another
Terminate between the first indicator lamp 2 and the positive pole of DC power supply 4, the equally detectable core to be detected that whether turns on is with shielding
With the presence or absence of short circuit between layer or steel armour.First indicator lamp 2 is the green LED that glow color is green, and second indicates
Lamp 3 is that glow color is red red light emitting diodes, that is, the positive pole of green LED and direct current supply electricity when connecting
The positive pole in source 4 is connected, and the first core 11 that the negative pole of dc source connects cable one end is connected, and the negative pole connection of green diode is public
One end of conllinear core 10, the other end of public core 10 are identical with the wire size of the first core 11 to be detected with the cable other end again
Core connection, while the positive pole of red light emitting diodes is connected on the positive pole and green LED of DC power supply 4
Between positive pole, the negative pole of red light emitting diodes is connected with one end of the second core 12, forms DC power supply 4 positive pole, green
Color light emitting diode positive pole, green LED negative pole, public core 10, the first core 11, the negative pole of DC power supply 4 return
Road, so as to detect the first core 11 whether turn on and the first core 11 and the second core 12 between whether short circuit, that is, work as green
Then judge that the first core 11 turns on during lumination of light emitting diode, otherwise the first core 11 ends, if while red light emitting diodes
It is luminous, then judge short-circuit between the first core 11 and the second core 12, otherwise not short circuit.
It is as follows according to the structure of cable core detection means, its workflow：
In use, carry out connection first, i.e., by electric iron and solder stick by the positive pole of DC power supply 4 and
The positive pole welding of one indicator lamp 2, one end of the negative pole of the first indicator lamp 2 and public core 10 are welded, public core 10 it is another
