[0034] In order to better understand the purpose, structure and function of the utility model, the portable cable fault tester of the utility model is further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 9 As shown, the embodiment of the utility model provides a portable cable fault tester, including a test box 100 for installing a protection test device, and a detection cavity 200 installed inside the test box 100 for detection, and the detection cavity 200 is embedded inside the test box 100.

[0036] A voltage unit 210 for detecting the cable is arranged at the upper end of the detection cavity 200, an electric ball gap adjustment unit 220 is arranged on one side of the voltage unit 210, a control button 230 for controlling the device is arranged on one side of the detection cavity 200, an output unit 240 for connection is provided on one side of the detection cavity 200, and a connecting wire 241 of the output unit 240 is received and wound by a receiving unit 250 provided inside a notch on one side of the lower end.

[0037] The storage portion 250 includes a mounting rod 252 fixedly installed inside the slot and a sliding sleeve rod 251 movably mounted on the upper end of the mounting rod 252 and slidable. The sliding sleeve rod 251 is slidably mounted on one side of the mounting rod 252. A rotating frame 253 for storing and winding the connecting wire 241 of the output portion 240 is rotatably mounted on one side of the sliding sleeve rod 251. The connecting wire 241 of the output portion 240 is rotatably wound around the upper end of the rotating frame 253. The rotating frame 253 is rotatably mounted on the inner side of the sliding sleeve rod 251 through the mounting shafts on both sides.

[0038] When using the detection chamber 200 to detect the cable, it is necessary to connect the connecting wire 241 of the output part 240 to the cable detection component. The sliding sleeve 251 can be pulled out to the outside, and then the rotating frame 253 is rotated to rotate it out. The connecting wire 241 wrapped around the upper end can be removed for use to avoid line entanglement. At the same time, it is also convenient to store the connecting wire 241 to facilitate cable detection. The entire device is lightweight and small in size, easy to carry and move, and suitable for rapid testing on site.

[0039] Both sides of the upper end of the rotating frame 253 are evenly provided with engaging grooves 254 for positioning the connecting wire 241 . The connecting wire 241 can be wound and stored through the engaging grooves 254 , so that the connecting wire 241 can be evenly wound and arranged and positioned.

[0040] A protective cover 270 for protecting each group of equipment and circuit boards is provided at the lower end of the detection chamber 200. Heat dissipation holes 271 for dissipating heat from the internal equipment of the protective cover 270 are provided on both sides of the protective cover 270. A rotating threaded barrel 260 for adjusting the height of the detection chamber 200 is movably installed inside the detection chamber 200 and the protective cover 270. A positioning screw 110 for adjusting the height is fixedly installed at the bottom of the test box 100. The rotating threaded barrel 260 is threadedly mounted on the upper end of the positioning screw 110. When using the detection chamber 200, the rotating threaded barrel 260 at the upper end of the detection chamber 200 can be rotated by rotating the handle of the rotating threaded barrel 260 to drive the rotating threaded barrel 260 to rotate and then push the detection chamber 200 out of the test box 100, so that the heat dissipation holes 271 opened on the side of the protective cover 270 at the lower end are exposed, so as to facilitate the heat dissipation of the protective cover 270 and at the same time elevate the operating position of the detection chamber 200 for easy operation.

[0041] There are three groups of heat dissipation holes 271. The inner side of the heat dissipation holes 271 is arranged with a first exhaust fan 273 and a second exhaust fan 274 for assisting in evacuating the heat of the protective cover 270. The first exhaust fan 273 is positioned to blow air inwardly, and the second exhaust fan 274 is positioned to exhaust air outwardly. The first exhaust fan 273 can increase the air flow rate inside the protective cover 270, and then the second exhaust fan 274 transports the hot air to the outside, thereby facilitating the heat dissipation inside the protective cover 270.

[0042] The first row of fans 273 and the second row of fans 274 are embedded in the disassembly and assembly slot 272 opened at the lower end of the protective cover 270 and are installed and fastened by screws, so that the first row of fans 273 and the second row of fans 274 can be easily disassembled and repaired.

[0043] A swivel leg 120 for supporting the test box 100 is rotatably installed at the lower end of the test box 100. The swivel leg 120 is arranged in a U shape and is embedded in a slot opened at the lower end of the test box 100. During operation, the swivel leg 120 can be rotated out to prop up the test box 100, which is convenient for the operator's detection operation.

[0044] A baffle door is rotatably installed outside the installation slot of the storage section 250 . The baffle door matches the size of the slot and is installed and connected via a torsion spring to protect the internal connecting wire 241 and the storage section 250 , preventing dust and other impurities from entering the storage section 250 .

[0045] Considering that the equipment has DC high voltage and poses a high voltage hazard to people operating the equipment, the tester adopts a design that can be started remotely and the boost stops and automatically discharges.

[0046] The body of the test box 100 is made of PP material, which has excellent insulation properties. The material hardly absorbs water, so its insulation properties will not be affected by humidity. In addition, PP material has a high dielectric constant and can withstand high voltages. It is suitable for making heated electrical insulation products. Its breakdown voltage is very high, making it suitable for use as electrical accessories.

[0047] Working principle of the portable cable fault tester: When using the detection chamber 200 to detect the cable, it is necessary to connect the connecting wire 241 of the output part 240 to the cable detection component, the sliding sleeve 251 can be pulled out to the outside, and then the rotating frame 253 is rotated to rotate it out, and the connecting wire 241 wrapped around the upper end can be removed for use to avoid line entanglement. At the same time, it is also convenient to store the connecting wire 241, which is convenient for cable detection. The whole device is designed to be lightweight and small in size, easy to carry and move, and suitable for rapid testing on site.
