[0026] like Figure 1-3 As shown, this utility model provides a wiring clamp for a lightning protection device detector, comprising: a pair of split clamp blocks 1; a fixed base 2, one end of which is provided with a sliding groove 3 adapted to the split clamp blocks 1, the pair of split clamp blocks 1 being slidably connected to the two inner sides of the sliding groove 3 respectively, and the other end of the fixed base 2 being provided with a screw hole 4; a screw tube 5, one end of which extends through the screw hole 4 into the sliding groove 3; and an adjusting mechanism, disposed within the screw tube 5 and movably connected to the pair of split clamp blocks 1, the adjusting mechanism being used to adjust the distance between the pair of split clamp blocks 1 and the screw tube 5. Figure 1-3As shown, a wiring clamp of a lightning protection device tester is first adjusted according to the wiring head to be tested, so that the gap between a pair of split clamps 1 is sufficient for the wiring head to be tested. Then, the clamping and releasing mechanism is used to clamp and release each wiring head to be tested, facilitating the testing of each wiring head. The split clamps 1 can be made of metals such as aluminum and copper. A pair of split clamps 1 are directly connected to a grounding resistance testing instrument via wires. The grounding resistance testing instrument is commercially available. The position of the screw tube 5 relative to the fixed seat 2 is adjusted by screwing the screw tube 5 and the screw hole 4. The distance between the split clamps 1 and the screw tube 5 can be adjusted by the adjustment mechanism. During the adjustment process, the clamping and releasing of each wiring head to be tested is completed, allowing the testing of each wiring head to be tested to be completed quickly through the adjustment mechanism.

[0027] Specifically, the two separate clamping blocks 1 have clamping surfaces on their sides that are close to each other, and inclined surfaces 6 are provided on their sides that are far apart from each other. The two separate clamping blocks 1 are slidably connected through the inclined surfaces 6 and the two inner sides of the sliding groove 3, respectively. Figure 1-3 As shown, the clamping surface is polished, and its surface roughness meets the process requirements for clamping connectors. This ensures effective clamping of connectors while avoiding scratches or damage to the surface of the clamped items. The split clamping blocks 1 are slidably connected through their own inclined surfaces 6 and the two inner sides of the slide groove 3. This sliding connection allows the split clamping blocks 1 to move smoothly and steadily within the slide groove 3. By sliding the split clamping blocks 1 on the two inner sides of the slide groove 3, the relative gap between a pair of split sliders can be adjusted, making it easy to clamp connectors of different specifications. This allows for quick testing of each connector of the same specification by simply adjusting the mechanism.

[0028] Specifically, a sliding block 7 is provided at one end of the screw tube 5 that extends into the sliding groove 3, and the sliding block 7 is slidably connected to the bottom of the sliding groove 3. A first handle 8 is provided at the other end of the screw tube 5. Figure 1-3 As shown, the shape of the sliding block 7 is adapted to the screw tube 5, both being circular. During the screwing process between the screw tube 5 and the fixed seat 2, the outer side of the sliding block 7 abuts against the bottom of the slide groove 3. When the screw tube 5 rotates, the sliding block 7 slides at the bottom of the slide groove 3, which can keep the direction of the screw stable. The screw can be easily adjusted by the first handle 8. The extension rod set on the first handle 8 increases the length of the lever arm, making it easier to operate the screw.

[0029] Specifically, each of the two separate clamping blocks 1 has a movable groove 9 at one end near the screw hole 4, and the two movable grooves 9 are interconnected. A stop portion 10 is provided at the edge of the movable groove 9 at one end of each of the two separate clamping blocks 1 near the screw hole. The adjusting mechanism and the stop portion 10 are slidably connected. Figure 1-3 As shown, the movable groove 9 of the split clamp 1 provides adjustment space for the adjustment mechanism. After adjusting the specifications of the connector to be tested using the solenoid 5, the adjustment mechanism is used to move its position within the movable groove 9, thereby cooperating to complete the clamping and releasing of the connector to be tested.

[0030] In some embodiments, the adjusting mechanism includes: an adjusting rod 11 and a sliding sleeve 12. The adjusting rod 11 is disposed inside the screw tube 5 and slidably passes through both ends of the screw tube 5. The sliding sleeve 12 slidably passes through the abutment 10 and extends into the movable groove 9. One end of the sliding sleeve 12 located in the movable groove 9 is provided with an edge 13, and a gap is provided between the edge 13 and the abutment 10. A gap is also left between the sliding sleeve 12 and the sliding block 7. A sliding hole is provided at the center of one end of the sliding sleeve 12 near the screw tube 5. The adjusting rod 11 slidably passes through the sliding hole and extends into the sliding sleeve 12. A sliding block 14 is provided at one end of the adjusting rod 11 located inside the sliding sleeve 12. The sliding block 14 is slidably connected to the inner side of the sliding sleeve 12. A spring 15 is also provided on the adjusting rod 11 located between the sliding block 14 and the sliding sleeve 12. Figure 1-3 As shown, after adjusting the solenoid 5, for a batch of test connectors of the same specification, the adjusting rod 11 is operated to move the sliding block 14 towards the end of the sliding sleeve 12 with the sliding hole. During this process, the spring 15 is compressed. Then, the adjusting rod 11 is pulled until the edge 13 of the sliding sleeve 12 abuts against the stop part 10. Then, a pair of split sliders are driven to continue moving until the sliding sleeve 12 abuts against the sliding plate. During this process, a pair of split sliders slide on the two inner sides of the slide groove 3, completing the adjustment of the gap between the pair of split sliders, thereby achieving quick clamping of the test connector. The release process is as follows: first, the adjusting rod 11 is pulled to remove the test connector, and then another connector is clamped. The setting of the spring 15 can help restore the distance between the sliding block 14 and the adjusting sleeve to the initial state after the adjusting rod 11 is released.

[0031] Specifically, a second handle 16 is provided at the end of the adjusting rod 11 away from the sliding sleeve 12. For example... Figure 1-3 As shown, the second handle 16 facilitates the operation of the adjusting rod 11. When adjusting the adjusting rod 11, the operator holds the first handle 8 and the second handle 16 with both hands, so that the adjusting rod 11 can be pulled out quickly.

[0032] Specifically, a fixing block 17 is provided at the edge 13 of both sides of the fixing base 2 near the slide groove 3, and a pair of split clamping blocks 1 are slidably connected to the fixing block 17 respectively. Figure 1-3 As shown, the fixing block 17 limits the split clamping block 1 within the slide groove 3 to prevent it from detaching during sliding. The connection method can be welding or bolt connection.

[0033] Specifically, each of the two separate clamping blocks 1 is further provided with a centering groove 18 at the end furthest from the movable groove 9. For example... Figure 1-3 As shown, the center slot 18 is located at the center of a pair of split clamps 1. Its combined shape is conical, which guides the wire to be tested during insertion and prevents the split clamps 1 from being clamped crookedly.
