detailed description

Below, in conjunction with accompanying drawing and specific embodiment, the utility model is described further:

Referring to Fig. 1, this embodiment provides a cable detection device, which includes a plurality of voltage detection modules, a controller, a first connector, a second connector, a power supply module, an alarm module, and a plurality of voltage detection modules equal in number to The LED lamp is used for detecting the cable, and thus also includes the cable to be detected. In order to better integrate the above-mentioned devices, a casing can be included. The LED lamp is arranged on the surface of the casing for easy viewing by the staff. On the casing, preferably outside the casing. The alarm module is preferably a buzzer, which can give an alarm when a disconnection of the cable is detected.

Wherein, the cable to be detected has multiple wire cores, one end of the first connector has multiple conductive ends, one end of the wire cores is electrically connected to the conductive ends one by one, and the other end of the wire cores is respectively connected to the LED lights. One corresponding electrical connection, the LED lamp is also connected to the voltage detection module one by one, the voltage detection module is connected to the second connector, the first connector and the controller are connected to the power module, the second The two connectors and the alarm module are both connected with the controller.

Both the first connector and the second connector have the function of conducting electricity. When testing, the number of conductive ends of the first connector is equal to the core of the cable, and the number of LED lights is the same as the number of conductive ends. However, in actual preparation, the number of conductive ends The quantity is preferably more than the quantity of conventional cable cores, in case it is not enough.

In this embodiment, a cable with four cores is taken as an example, and the first connector has four conductive ends for matching with the cores of the cable, and at the same time, four LED lights correspond to the cores respectively. For the convenience of description, the four cores are named as the first core, the second core, the third core, and the fourth core, and also include the first voltage detection module, the second voltage detection module, the third voltage detection module and the fourth In the voltage detection module, the LED lamps are respectively named as LED lamp 1, LED lamp 2, LED lamp 3 and LED lamp 4. The first wire core corresponds to LED lamp 1, the second wire core corresponds to LED lamp 2, and the third wire core corresponds to LED lamp 2. The lamp 3 corresponds, the fourth wire core corresponds to the LED lamp 4, and the first voltage detection module corresponds to the LED lamp 1, and so on. After the connection between all devices is completed, if the wire core is not broken, each wire core, that is, its corresponding LED lamp will form a current loop with the power module and alarm module, so that the LED lamp will work and light up. When the four wire cores are disconnected, the voltage detection module respectively detects that the corresponding LED lights have a voltage signal, and sends the voltage signal to the controller, so that the controller controls the alarm module to not work. When any one of the four cores is broken, take the first core as an example, if the first core is broken, the first core cannot form a circuit loop during detection, and the LED light 1 will not light up. , the corresponding first voltage detection module detects no voltage, and thus sends a signal to the controller, and the controller controls the alarm module to issue an alarm. When the staff hears the alarm, they can judge that there is a disconnection fault in the cable, and can specifically determine which core wire is broken according to the off LED light, which is convenient for maintenance.
