A jack 9 is installed on the top of one of the upper box covers 3, and the other upper box cover 3 is slidably connected with an L-shaped plug rod 10, and the tops of the two spring pieces 7 are slidably connected with plug pieces 11. The cable fault location detector 1 has a design that is easy to carry and quickly deploy, so that it can be put into use quickly when a distribution network fault occurs. The base 2 is made of insulating material to ensure safety during use. A sealing gasket is provided between the upper box cover 3 and the bottom groove 4 of the base 2 to enhance the stability of cable fixation and waterproof performance.

[0029] See also Figure 3 and Figure 4 The limiting mechanism 8 includes: a movable block 84, an installation groove 81 is equidistantly provided at the bottom end of the base 2, and the inner wall of the installation groove 81 is provided with a movable groove 82, and a spring 83 is fixedly connected to the inner wall of the movable groove 82, and a movable block 84 is slidably connected to the inner wall of the movable groove 82, one side of the movable block 84 is fixedly connected to one end of the spring 83, and a first locking tooth 85 is fixedly connected to the side of the movable block 84 not close to the spring 83, and a second locking tooth 86 is fixedly connected to the side of the extension block 5 close to the movable groove 82, and the first locking tooth 85 is meshed with the second locking tooth 86. When the extension block 5 is rotated, the second locking tooth 86 rotates accordingly, and the first locking tooth 85 is squeezed to make it slide into the movable groove 82, and the spring 83 is compressed. The meshing part of the first locking tooth 85 and the second locking tooth 86 is made of wear-resistant material to ensure stability under long-term use.

[0030] The working principle of the distribution network fault locating device provided by the utility model is as follows: First, the distribution network fault locating device is mainly composed of a cable fault locating detector 1, a base 2, an upper box cover 3, an extension block 5, a placement slot 6, a spring piece 7 and a limit mechanism 8.

[0031] When a fault occurs in the distribution network, the operator first places the cable on the base 2, and fixes the two ends of the cable in the upper box cover 3 and the bottom groove 4. At this time, the sealing gasket between the upper box cover 3 and the bottom groove 4 of the base 2 can ensure the stability and waterproof performance of the cable fixation, ensuring that the cable will not loosen or be affected by the external environment during the detection process.

[0032] Next, the operator places several cables in the cable in the placement slots 6 on the extension block 5. Two semicircular springs 7 are symmetrically fixedly connected to the top of each placement slot 6, and the two springs 7 can easily realize the rapid disassembly and assembly of the cables. When the cables are placed between the springs 7, the springs 7 will use their elasticity to fix the cables to prevent the cables from sliding or falling off during the detection process.

[0033] Then, the operator starts the cable fault location detector 1 to locate the cable fault. The cable fault location detector 1 is designed to be easy to carry and quickly deployed, so when a distribution network fault occurs, it can be quickly put into use to improve the efficiency of fault handling.

[0034] After locating the faulty cable, the operator can mark the faulty cable by operating the limiting mechanism 8. The limiting mechanism 8 is mainly composed of a movable block 84, a mounting slot 81, a movable slot 82, a spring 83, a first locking tooth 85, and a second locking tooth 86. When the operator rotates the extension block 5, the second locking tooth 86 will rotate accordingly and squeeze the first locking tooth 85, causing it to slide into the movable slot 82 and compress the spring 83. In this way, the meshing relationship between the first locking tooth 85 and the second locking tooth 86 will change, causing the extension block 5 to rotate relative to the base 2, thereby driving the placement slot 6 and the cable therein to bend. This bending can serve as an obvious mark to help operators quickly identify faulty cables.

[0035] In addition, the device is also designed with a socket 9 and an L-shaped plug rod 10, as well as an insert 11 at the top of the spring 7. These designs are all for the convenience of operators to operate when fixing and removing cables, and improve the convenience and efficiency of operation.

[0036] In summary, the distribution network fault locating device, through its unique design and mechanism coordination, realizes the rapid positioning, fixation and marking of faulty cables in the distribution network, providing an effective solution for fault handling in the distribution network.
