In order to achieve the above object, the utility model adopts the following technical solutions: a cable detection device, which is characterized in that: it includes a controller, the controller is connected in series with the power supply module, the current limiting resistor, and the main switch in sequence, and the other part of the controller is One end is respectively connected to the first to nth current detection modules, the first to nth current detection modules are respectively connected to the first to nth LED lamps, and the first to nth LED lamps are respectively connected to the first to nth toggle The other end of the main switch is respectively connected to the other end of the first to n toggle switches, and both ends of the first to n toggle switches are provided with wires for connecting the cables. Core terminal, where n is a positive integer.

Further, an alarm module is also included, and the alarm module is connected with the controller.

Further, the alarm module is a buzzer.

Further, it also includes a box body, the first to nth LED lamps are arranged on one side of the front of the box body from top to bottom, and the first to nth toggle switches are arranged in the middle of the front of the box body and connected to the The first to nth LED lamps correspond one by one, and the connecting terminals are correspondingly arranged on both sides of the first to nth toggle switches.

Compared with the prior art, the utility model has the following beneficial effects: when the utility model detects that a certain wire core is disconnected, the corresponding indicator light is off, and the buzzer sounds to give an acousto-optic alarm; and the utility model The new type can realize self-test through the toggle switch, avoiding the deviation of the test result caused by the damage of the circuit of the device itself.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Please refer to Figure 1. This embodiment provides a cable detection device, including a controller, the controller is connected in series with the power supply module, the current limiting resistor, and the main switch in sequence, and the other end of the controller is respectively connected to the first to nth The current detection module is connected, the first to nth current detection modules are respectively connected to the first to nth LED lamps, the first to nth LED lamps are respectively connected to the first to nth toggle switches, and the main switch The other ends are respectively connected to the other ends of the 1st to nth toggle switches, and both ends of the 1st to nth toggle switches are provided with terminals for connecting the wire cores in the cable, where n is positive integer, n=4 in this embodiment.

In this embodiment, an alarm module is also included, and the alarm module is connected to the controller; the alarm module is a buzzer.

Please refer to FIG. 2 , it also includes a box body 1, the first to fourth LED lamps 11 are arranged on one side of the front side of the box body from top to bottom, and the first to fourth toggle switches 12 are arranged on the front side of the box body 1 and corresponding to the first to fourth LED lamps 11 one by one, and the connecting terminals 13 are correspondingly arranged on both sides of the first to fourth toggle switches 12; the connecting terminals arranged in sequence in each row in Fig. 2 13. The toggle switch 12, the connection terminal, and the LED lamp 11 are electrically connected to form a detection unit to realize the detection of a wire core.

In order to allow ordinary technical personnel to better understand the technical solution of the utility model, the utility model will be introduced in detail below in conjunction with the schematic diagram of the utility model in use.

Please refer to Figure 2. When testing a cable with 3 wire cores, first turn off the main switch and the 1st to 4th toggle switches to perform self-testing. When the circuit is normal, all LED lights are on and the buzzer does not sound ring. When the self-test is normal, three toggle switches are selected to be disconnected, and the remaining toggle switch is still closed, such as the 2nd to 4th toggle switches in the figure, and the 3 cores of the cable are connected to the On the terminals corresponding to the 2nd to 4th toggle switches, if the 3 cores are normal, the 1st to 4th current detection modules receive the corresponding current signals, the 1st to 4th LED lights are on and the buzzer is off. Sound; when any wire core is disconnected, the corresponding LED light is out of power and the corresponding current detection module cannot detect the current signal, the controller controls the buzzer to sound, prompting the detection personnel to carry out post-processing. That is, only when all current detection modules detect current signals, the controller controls the buzzer not to sound.

The above descriptions are only preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
