Description
Technical Field
[0001] This utility model relates to the field of cable branch box technology, and in particular to a cable grounding tool for a cable branch box. Background Technology
[0002] Cable grounding tools are specialized safety devices adapted to cable branch boxes, used for cable line branching, switching, and fault isolation of core power equipment. With the upgrading of urban power distribution networks and industrial park power supply networks, medium-voltage cable lines are gradually replacing overhead lines as the mainstream due to their advantages of small footprint, reliability, and immunity to weather conditions. As a node hub of cable lines, cable branch boxes have expanded their application scenarios from urban main roads and residential areas to new energy power plants and key areas of data centers. The frequency of operation and maintenance and safety requirements have increased significantly, providing a core demand scenario for the development of cable grounding tools. During cable operation and insertion / removal, static electricity easily accumulates due to friction between the conductor and the insulation layer. Grounding tools can conduct static electricity away in real time, preventing electrostatic discharge from breaking down the insulation layer and igniting inside the cabinet, thus ensuring the stable insulation performance of the equipment.
[0003] The cable grounding tool in the cable branch box is the core device for establishing a reliable connection between the cable conductor and the grounding system. Currently, most existing devices adopt a rigid connection design, with the clamp and operating rod connected by fixing screw holes and welding. The flat-mouth spiral grounding wire is completely fixed in the insulated operating rod, and the angle cannot be adjusted according to the operation requirements. This structure means that a single tool can only be adapted to a specific specification of cable. The replacement process is cumbersome and relies on auxiliary tools, resulting in a significant reduction in operation efficiency, an increase in accident risk, a significant reduction in the overall life of the tool, an increase in maintenance costs, a high degree of difficulty in operation, reliance on manual adjustment, inability to adapt to multiple specifications of components, and high tool inventory costs. Utility Model Content

[0018] Please see the appendix Figure 1 , attached Figure 2 and attached Figure 3 A cable grounding tool for a cable branch box includes a clamp body 1. A fixing pin 3 is slidably connected to the top of the clamp body 1. A connecting plate 4 is slidably connected to the outer wall of the fixing pin 3.

A support plate 9 is fixedly connected to the top of the rotating column 8. A handle 10 is fixedly connected to the middle of the outer wall of the support plate 9. Fixing pins 11 are slidably connected to the front and rear ends of the outer wall of the support plate 9. A telescopic mechanism 2 is provided on the right side of the clamp body 1. The telescopic mechanism 2 is used to adapt to complex working spaces, has strong operational flexibility, simplifies the operation process, reduces manual dependence, ensures safe distance, reduces accident risk, reduces maintenance costs, and is suitable for multi-scenario operations. Specifically, the top of the clamp 1 is slidably connected to a fixing pin 3. The outer wall of the fixing pin 3 is slidably connected to the connecting plate 4, allowing the connecting plate 4 to slide on the outer wall of the fixing pin 3. The right side of the outer wall of the connecting plate 4 is fixedly connected to a rotating shaft 5. Limiting blocks 6 are fixedly connected to both ends of the rotating shaft 5. A support block 7 is fixedly connected to the outer wall of the limiting block 6, allowing the support block 7 to be stably fixed on the limiting block 6.

[0019] Please see the appendix Figure 1 and attached Figure 4The telescopic mechanism 2 includes a protective shell 201. A rotating shaft 202 is rotatably connected to the inner wall of the protective shell 201. A roller 203 is fixedly connected to the outer wall of the rotating shaft 202.

A slider 206 is slidably connected to the bottom of the outer wall of the roller 203. A limit post 207 is fixedly connected to the top of the outer wall of the slider 206. A groove 208 is slidably connected to the bottom of the outer wall of the slider 206. Specifically, the protective shell 201 provides overall protection and support. The inner wall rotating shaft 202 allows the roller 203 to rotate flexibly. By turning the arc-shaped handle 204, the roller 203 rotates accordingly. Through contact with the outer wall, it pushes the slider 206 to slide linearly along the slide groove 208, realizing the length extension and retraction adjustment. After the adjustment is in place, the pin 205 slides along the arc-shaped handle 204 and inserts into the positioning hole to lock the roller 203. The top limiting post 207 of the slider 206 is embedded in the groove of the slide groove 208 to limit lateral displacement. Together with the friction between the roller 203 and the slider 206, a double self-locking effect is formed to ensure that the structure is stable and does not loosen after extension and retraction, adapting to different working space requirements.
[0020] Please see the appendix Figure 1 and attached Figure 5 A connecting block 12 is fixedly connected to the right side of the outer wall of the clamp 1. A telescopic rod 13 is slidably connected to the right side of the outer wall of the connecting block 12. An insulating rod 14 is fixedly connected to the right side of the outer wall of the telescopic rod 13. A rubber handle 15 is fixedly connected to the outer wall of the insulating rod 14. A screw 16 is connected to the top of the telescopic rod 13. A movable clamping block 17 is threadedly connected to the outer wall of the screw 16. Specifically, the clamp body 1 serves as the load-bearing base. The connecting block 12 on the right side of the outer wall slides in conjunction with the telescopic rod 13. The telescopic rod 13 is telescopic and adjustable to accommodate different working distances of the cable branch box. The insulating rod 14 on the right side of the telescopic rod 13 provides insulation protection to prevent electric shock during operation. The rubber handle 15 on the outer wall increases grip friction to prevent hand slippage. The screw 16 at the top of the telescopic rod 13 is threadedly connected to the movable clamping block 17. Rotating the screw 16 can drive the movable clamping block 17 to move up and down, cooperating with the clamp body 1 to clamp it tightly, ensuring stable conductor contact during grounding and forming a reliable grounding circuit.
[0021] Please see the appendix Figure 1 and attached Figure 3 A gasket 18 is fixedly connected to the top of the outer wall of the clamp 1. A bolt 19 is threadedly connected to the outer wall of the clamp 1. A nut 20 is fixedly connected to the top of the bolt 19. A connecting block 12 is fixedly connected to the right side of the clamp 1. A telescopic rod 13 is fixedly connected to the outer wall of the connecting block 12. A support block 7 is fixedly connected to the bottom of the telescopic rod 13. Connecting holes 21 are fixedly connected to the front and rear sides of the top of the support block 7. Specifically, the gasket 18 on the top of the outer wall of the clamp 1 can prevent damage to the cable insulation layer during clamping, while enhancing the fit with the cable. The bolt 19 on the outer wall of the clamp 1 is threaded with the top nut 20. After tightening, it can lock the cable conductor and ensure stable conductivity.

The connecting holes 21 on the front and rear sides of its top can be used to connect the grounding flexible wire terminal to build a complete grounding circuit.
[0022] Working principle: The clamp body 1 is the basic support. The fixing pin 1 3 is slidably connected to the connecting plate 4, providing a fixed connection for the connecting plate 4. The rotating shaft 2 5 on the right side of the outer wall of the connecting plate 4 and the limiting blocks 6 at both ends form the first locking. The rotating column 8 and the support block 7 are fixedly connected. Through the handle 10, the support plate 9 fixed to the top of the rotating column 8 will be driven to rotate, so that the rotating column 8 can rotate in the support block 7 to achieve adjustment. When replacing parts, the fixing pin 2 11 at the front and rear ends of the outer wall of the support plate 9 can unlock the components. The connecting plate 4 is unlocked by sliding the fixing pin 1 3 on the clamp body 1, which is coordinated with the rotation of the rotating column 8. The protective shell 201 provides support, and the rotating shaft 202 on the inner wall provides a fulcrum for the roller 203. During operation, the arc-shaped handle 204 is pushed to rotate the roller 203 around the rotating shaft 202. The roller 203 pushes the slider 206 to slide along the slide groove 208 through the contact of the outer wall, realizing the extension and retraction adjustment. After the adjustment is in place, the pin 205 is slid into the positioning hole of the arc-shaped handle 204 to lock the roller 203. At the same time, the limiting post 207 on the top of the slider 206 restricts its lateral displacement. The friction between the roller 203 and the slider 206 maintains the position, forming a double self-locking.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
