[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a portable multi-core cable fault detector, which has the following advantages:

[0014] This portable multi-core cable fault detector works by placing the detector body inside a placement slot. A first servo motor is then activated to rotate a worm gear, which in turn drives a transmission shaft and a drive bevel gear. The driven bevel gear then drives a first threaded rod to rotate. During rotation, the first threaded rod causes two moving blocks and two clamping plates to move relative to each other until two first rubber pads are tightly fitted against the left and right sides of the detector body, thus clamping and fixing it in place. Next, two second servo motors are activated to rotate two drive gears, which in turn drive two second threaded rods to rotate. During rotation, the two second threaded rods cause two pressure blocks to move downwards until both second rubber pads are tightly fitted against the top of the detector body, further pressing and fixing it in place. This process secures the detector, preventing it from shaking or being bumped during transport, thus protecting it. Attached Figure Description

A second threaded hole, which is adapted to the two second threaded rods 15, is opened at the bottom of each of the two pressure blocks 16. A second rubber pad 17 is fixedly installed at the bottom of each of the two pressure blocks 16.

[0025] A second drive assembly 18 is fixedly installed on the top of the opposite sides of each of the two moving blocks 9, with one end fixedly connected to the outside of each of the two second threaded rods 15. The second drive assembly 18 includes a second servo motor 181. The second servo motor 181 is fixedly installed on the top of the opposite sides of each of the two moving blocks 9. The model of the second servo motor 181 can be YB2-315S-6-70. The output shafts of the two second servo motors 181 are fixedly mounted with drive gears 182. The outside of each of the two second threaded rods 15 is fixedly mounted with a driven gear 183 located above the moving block 9, with one end meshing with the two drive gears 182 respectively. All electrical components mentioned in the text are electrically connected to the controller and the battery.

[0026] Working principle: By placing the fault detector body 6 inside the placement slot 5, the controller starts the first servo motor 131 to drive the worm gear 133 to rotate, which in turn drives the transmission shaft 121 and the drive bevel gear 122 to rotate via the worm wheel 134. The driven bevel gear 123 then drives the first threaded rod 8 to rotate. During the rotation of the first threaded rod 8, the two moving blocks 9 and the two clamping plates 10 move relative to each other until the two first rubber pads 11 are tightly attached to the left and right sides of the fault detector body 6, thereby clamping and fixing the fault detector body 6. Next, the controller starts two second servo motors 181 to drive the two drive gears 182 to rotate, which in turn drives the two second threaded rods 15 to rotate via the two driven gears 183. During the rotation of the two second threaded rods 15, the two pressure blocks 16 move downward. Until both second rubber pads 17 are tightly fitted to the top of the fault detector body 6, the fault detector body 6 is further pressed and fixed to prevent it from shaking or bumping in the carrying case during transport, thus protecting the fault detector. Then, close the case cover 2, and the case 1 and the fault detector body 6 can be carried by the handle 3. When the fault detector body 6 needs to be used, open the case cover 2, and then start the two second servo motors 181 through the controller to make them rotate in opposite directions, thereby driving the two pressure blocks 16 to move upward. Then, start the first servo motor 131 to rotate in opposite directions, thereby driving the two moving blocks 9 and the two clamping plates 10 to move in opposite directions, thereby releasing the fixation of the fault detector body 6. At this time, the fault detector body 6 can be taken out from the inside of the case 1 to perform fault detection work on multi-core cables.

[0027] In summary, this portable multi-core cable fault detector, by placing the fault detector body 6 inside the placement slot 5, activates the first servo motor 131 to drive the worm gear 133 to rotate, which in turn drives the transmission shaft 121 and the drive bevel gear 122 to rotate via the worm wheel 134. The driven bevel gear 123 then drives the first threaded rod 8 to rotate. During rotation, the first threaded rod 8 causes the two moving blocks 9 and the two clamping plates 10 to move relative to each other until the two first rubber pads 11 are tightly fitted against the left and right sides of the fault detector body 6, thus clamping and fixing the fault detector body 6. Next, two second servo motors 181 can be activated to drive the two drive gears 182 to rotate, which in turn drives the two second threaded rods 121 to rotate via the two driven gears 183. As the threaded rod 15 rotates, the two second threaded rods 15 drive the two pressure blocks 16 to move downwards until the two second rubber pads 17 are tightly pressed against the top of the fault detector body 6. This further presses and fixes the fault detector body 6, ultimately achieving the purpose of fixing the fault detector and preventing it from shaking or bumping in the carrying case. This protects the fault detector and solves the problem that existing multi-core cable fault detectors are prone to shaking or even bumping against the case in actual use because the carrying cases are usually simple in structure and do not have the function of fixing the fault detector. This can cause the fault detector to shake or even bump against the case, which can damage the fault detector and make it unusable.
