Description

Efficient Cable Detector

technical field

Background technique

The work of cable detection is very important, and the workload is very heavy. In particular, it is relatively difficult to detect some cables with plugs. If it is directly connected to the device for testing, it is easy to burn the device. If there is a complete machine failure, there will be problems such as not easy to find the cause.

Most of the existing low-cost cable detectors have a single function and a single interface form, and can only detect whether the cable is on or off, such as a network cable detector. However, short-circuit detection is essential in the cable production and testing process, and the workload of short-circuit detection is very large, which is several times, dozens of times or even hundreds of times that of continuity detection. Now the method of manual detection is usually adopted. However, manual detection has disadvantages such as low efficiency and easy misjudgment. Taking a four-core cable as an example, there are 8 points for on-off detection and 9 points for short-circuit detection. One cable needs to detect 17 points, 40,000 wires are 680,000 points, and two people need to operate together. The cost is high, the efficiency is low, and human error is inevitable.

After retrieval, there is no report on high-efficiency cable continuity and short-circuit detection equipment at home and abroad.

Connect to the negative pole of the power supply 14.

Figure 4 is a schematic diagram of the common terminal circuit in the utility model, wherein the common terminal 8-3 of the non-resetting toggle switch 8 is connected to the positive pole of the power supply 14; The positive connection of the first on-off indicator light 1, the second on-off indicator light 2, the third on-off indicator light 3, and the fourth on-off indicator light 4 in the test circuit; The terminal 8-2 is connected to the anodes of the first short-circuit indicator light 5, the second short-circuit indicator light 6, and the third short-circuit indicator light 7 in the short-circuit test circuit.

In this embodiment, the non-resetting toggle switch 8 is a single-pole toggle switch; the first reset toggle switch 9 , the second reset toggle switch 10 and the third reset toggle switch 11 are all double-pole toggle switches.

The switching of the on-off detection and the short-circuit detection of the utility model is controlled by a non-resetting toggle switch 8; the on-off and short-circuit state detection is realized by controlling three reset toggle switches. The first reset toggle switch 9 controls the on-off detection, and the second reset toggle switch 10 and the third reset toggle switch 11 control the short circuit detection. The specific working process is:

Put the non-resetting toggle switch 8 in the on-off position, supply power to the first on-off indicator light 1, the second on-off indicator light 2, the third on-off indicator light 3, and the fourth on-off indicator light 4, and push up the first on-off indicator light A reset toggle switch 9, the first on-off indicator light 1 and the second on-off indicator light 2 are on; push down the first reset toggle switch 9, the third on-off indicator light 3 and the fourth on-off indicator light 4 are on , at this time, it means that the corresponding pins of the cable are connected. If any indicator light is off, it means that the cable of the corresponding pin is not connected.

Put the non-resetting toggle switch 8 in the short-circuit position, and supply power to the first short-circuit indicator light 5, the second short-circuit indicator light 6, and the third short-circuit indicator light 7. The second reset toggle switch 10 detects whether the pin 1 is short-circuited with other pins: the second reset toggle switch 10 is pushed up or down, and the first short-circuit indicator light 5 is not on. If the first short-circuit indicator light 5 is on, then the 1 pin 12-1 is short-circuited with other pins. When the third reset toggle switch 11 is pushed up, the second short-circuit indicator light 6 is off; if the second short-circuit indicator light 6 is on, there is a short circuit between pin 2 and other pins other than pin 1. When the third reset toggle switch 11 is pushed down, the third short-circuit indicator light 7 is off; if the third short-circuit indicator light 7 is on, the pin 3 and the pin 4 are short-circuited.

After testing, the cable detector of this embodiment improves the detection efficiency of the four-core cable by more than 10 times compared with manual detection.

If each toggle switch uses a toggle switch with three or more contacts, the number of toggle switches can be reduced, the operation is simpler, and the efficiency is higher. Especially for the detection effect of cables with more than four cores is particularly obvious.

On this basis, other linear detectors can be made, such as seven-core cable detectors, ten-core cable detectors, etc. At this time, it is only necessary to replace the corresponding number of LED lights and connectors and make corresponding connections. Among them, the ten-core cable can increase the efficiency by more than 50 times.

Of course, the equivalent transformation or replacement of each component, positional relationship and connection mode of the present invention without changing its function also falls within the scope of protection of the present invention.

The technologies not disclosed in the description of the utility model belong to the known technologies in the art.
