Description

Technical Field

[0001] The utility model relates to the technical field of cable grounding tools, in particular to a cable grounding tool for a cable branch box. Background Art

[0002] Cable grounding tools for cable branch boxes are primarily used to limit induced voltages and fault overvoltages on the metal sheath of power cables, as well as to prevent the formation of circulating currents within the sheath. The grounding tool is designed to better penetrate the conductive rod into the grounding box, ensuring a good ground connection and preventing leakage in the cable branch box.

[0003] According to a cable grounding tool for a cable branch box disclosed on the patent website (authorization publication CN 212695349U), "A cable grounding tool for a cable branch box includes a wire clamping column, a grounding terminal copper ring is clamped on the wire clamping column, a grounding wire connection assembly is fixedly provided on the grounding terminal copper ring via a grounding terminal copper sheet, and a copper sleeve is fixedly provided at the bottom of the wire clamping column, and the copper sleeve is fixedly engaged with the cable terminal connector assembly."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use, the utility model clamps the external grounding wire in the grounding wire connecting assembly through the clamping force between the roller and the inclined shell, the copper sleeve is inserted into the inside of the copper inner tube, and the three copper clamping pieces are clamped and separated by the up and down movement of the arc ring plate, and the wire clamping column rod is conveniently fixed to the cable terminal through the cable terminal connector assembly. However, in actual use, the device fixes the grounding wire on the device through the clamping force between the roller and the shell. Since the clamping distance between the roller and the shell is consistent, it is impossible to ensure that the grounding wire is completely fixed on the device when clamping grounding wires of different thicknesses, and thus it is impossible to adjust the appropriate clamping force, making it difficult to prevent the grounding wire from loosening due to external force after clamping, thereby making the overall connection between the grounding wire and the device poor. Therefore, it is necessary to improve a cable grounding tool for a cable branch box. Utility Model Content

[0010] Preferably, grooves are provided at corresponding positions of the pressing roller and the roller frame, and the pressing roller is slidably connected in the groove, so that the pressing roller can fix the grounding wire and the grounding terminal copper sheet.

[0011] Preferably, the limiting plate is slidably connected to the interior of the sliding frame, and the clamping block is inserted into the bottom of the clamping strip, so that the clamping block is always in contact with the clamping strip.

[0012] Preferably, the clamping assembly includes a positioning block, which is slidably connected to the inside of the sliding frame, a pull plate is fixedly connected to the bottom of the positioning block, and a second spring is fixedly connected between the positioning block and the sliding frame to facilitate fixing the pressure rod.

[0016] Compared with the prior art, the present invention provides a cable grounding tool for a cable branch box, which has the following beneficial effects:

[0017] 1. The cable grounding tool of the cable branch box fixes the pressure roller according to the thickness and size of the grounding wire through the fixed clamping mechanism, so that the device can adjust the appropriate clamping position and distance according to the thickness and size of different grounding wires, thereby ensuring that the grounding wire can be completely fixed on the device, preventing the grounding wire from loosening after being fixed, thereby further improving the overall connection effect of the device.

[0030] The fixing and clamping mechanism 6 includes a fixing component 61 and a clamping component 62. The clamping component 62 is arranged inside the fixing component 61.

[0031] The fixing assembly 61 includes a roller frame 611, which is fixedly connected to the outside of the grounding terminal copper sheet 5. The front of the roller frame 611 is slidably connected to the sliding frame 612, and the inside of the sliding frame 612 is slidably connected to the pressure rod 613. The backs of all the pressure rods 613 are fixedly connected to the limiting column 614, and the limiting column 614 is movably connected to the limiting plate 615 on the outside. The top of the limiting plate 615 is fixedly connected to a clamping block 616, and a spring 617 is fixedly connected between the limiting plate 615 and the sliding frame 612. The front of the roller frame 611 is fixedly connected to a clamping strip 618, and the back of the sliding frame 612 is fixedly connected to a pressure roller 619, which is convenient for quickly fixing and clamping the connecting line, thereby improving the connection effect between the device and the connecting line.

[0032] Furthermore, grooves are provided at corresponding positions of the pressure roller 619 and the roller frame 611 , and the pressure roller 619 is slidably connected in the grooves, so that the pressure roller 619 can fix the grounding wire and the grounding terminal copper sheet 5 .

[0033] Furthermore, the limiting plate 615 is slidably connected to the interior of the sliding frame 612 , and the clamping block 616 is inserted into the bottom of the clamping strip 618 , so that the clamping block 616 is always in contact with the clamping strip 618 .

[0034] Furthermore, the clamping assembly 62 includes a positioning block 621, which is slidably connected to the inside of the sliding frame 612. A pull plate 623 is fixedly connected to the bottom of the positioning block 621, and a spring 2 622 is fixedly connected between the positioning block 621 and the sliding frame 612 to facilitate fixing the pressure rod 613.

[0035] Furthermore, a groove is provided at the corresponding position of the positioning block 621 and the pressure rod 613, and the positioning block 621 is inserted into the groove, so that the inclined block can be inserted into the corresponding groove of the pressure rod 613 to fix it.

[0036] Example 2:

[0037] See also Figure 5 , and combined with Example 1, it is further obtained that the cable connector connection mechanism 8 includes a copper tube connection sleeve 81, the copper tube connection sleeve 81 is sleeved on the outside of the copper tube, the copper tube is connected to the internal rotation connection with a bidirectional screw 82, the bidirectional screw 82 is externally screwed with a threaded block 83, and the back of the threaded block 83 is fixedly connected with a splint 84, which is convenient for quickly fixing and connecting the copper sleeve 7.

The movement causes the pressure roller 619 to gradually approach the ground wire, so that it completes the contact with the ground wire. When it moves to the appropriate position, by pressing the pressure rod 613 to the right, it drives the limit plate 615 to move upward, and then synchronously drives the card block 616 to be stuck in the bottom of the card strip 618. When the pressure rod 613 enters the interior of the slide frame 612, its positioning block 621 corresponds to the groove corresponding to the pressure rod 613, and under the elastic force of the spring 2 622, the positioning block 621 is inserted into the groove corresponding to the pressure rod 613, thereby completing the fixation of its pressure rod 613, so that the card block 616 is always stuck in the bottom of the card strip 618, thereby completing the fixation of its pressure roller 619.
