Description

Technical Field

[0001] This utility model relates to the field of puncture wire clamp technology, specifically to a puncture wire clamp with good sealing effect. Background Technology

[0002] An insulating piercing clamp is a tool used to connect electrical wires. Its design allows for wire connections without disconnecting or stripping the wire insulation. It mainly consists of an insulating shell, a piercing blade, waterproof gaskets, and a torque bolt. When a cable needs to be branched or spliced, the branch cable terminal is inserted into the waterproof terminal cap. After determining the branch position, the torque nut on the clamp is tightened with a socket wrench. During this process, the contact blade pierces the cable insulation layer and comes into contact with the conductor. However, the contact area between the two waterproof gaskets in existing insulating piercing clamps is relatively limited, resulting in poor sealing and allowing rainwater to easily enter, thus compromising safety.

[0003] To solve the above-mentioned technical problems, the prior art Chinese patent with publication number CN222146690U discloses an insulating piercing clamp with good sealing performance, including an upper insulating shell and a lower insulating shell, with a bolt passing through between the upper and lower insulating shells, and piercing blades installed on both the upper and lower insulating shells. An upper waterproof rubber pad is installed on one side of the upper insulating shell, and a lower waterproof rubber pad is installed on one side of the lower insulating shell.

[0004] While the aforementioned existing technical solutions can increase the sealing performance at the point of contact with the wire, the sealing protrusions that contact the wire are directly fixed to the upper and lower waterproof gaskets. When the sealing protrusions show signs of aging or damage, it will directly affect the sealing effect at the point of contact with the wire. Furthermore, it is difficult for workers to separate, maintain, or directly replace these sealing protrusions fixed to the upper and lower waterproof gaskets, which in turn affects the sealing effect at the point of contact with the wire during subsequent use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0024] A piercing clamp with good sealing performance includes two sets of insulating shells 1, with a bolt 2 passing through between them. Piercing blades 3 are installed at both ends of the opposite sides of the two sets of insulating shells 1. A bracket 4 is installed around the piercing blades 3 on the opposite sides of the two sets of insulating shells 1. A water-blocking plate 6 is installed on the top of one set of insulating shells 1, and a fixing plate is installed on one side of the other set of insulating shells 1. A pull rope is installed at one end of the fixing plate, and a waterproof cap 20 is installed at the other end of the pull rope. A torque nut 7 is threaded to one end of the bolt 2. A sealing fitting is installed on the bracket 4. The fitting and sealing mechanism includes a connecting component and a sealing component. The connecting component is used to position the sealing component, and the sealing component is used to increase the sealing effect at the fitting point with the wire. When in use, the sealing component can be positioned by the connecting component, and the sealing component increases the sealing effect at the fitting point with the wire. The structure is simple and easy to operate. When the fitting cover 8 is damaged or aged, it can be quickly disassembled and replaced in time to ensure the sealing performance at the fitting point between the piercing clamp and the wire. When the piercing blade 3 squeezes the wire, the sealing plate 21 will also close the sides of the two sets of insulating shells 1, further increasing the sealing effect.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the sealing assembly includes a bonding cover 8 that overlaps the top two ends of the bracket 4. A side plate 22 is installed on one side of the bonding cover 8. The height of the bonding cover 8 is higher than the tips of the two sides of the piercing blade 3. First, the torque nut 7 on the twisting bolt 2 can cause the water blocking plate 6 to move the upper insulating shell 1 downward, so that the bonding covers 8 on the two sets of brackets 4 are pressed against the upper and lower ends of the outer wall of the line. During the compression process, a certain degree of deformation can be performed, so that the piercing blade 3 can approach the outer wall of the line and achieve the piercing effect.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a sealing plate 21 is installed at the other end of the side plate 22. The side plate 22, the sealing plate 21, and the bonding cover 8 are all made of rubber. Then, as the two sets of insulating shells 1 approach each other, the upper insulating shell 1 will gradually contact and squeeze the sealing plate 21 to retract, so that one end of the sealing plate 21 is tightly attached to the outer wall of the upper insulating shell 1, achieving the effect of sealing the side. The bonding covers 8 at the upper and lower ends further enhance the overall sealing effect of the wire clamp.

[0027] In this embodiment, as Figure 3 , Figure 4 and Figure 5As shown, the connecting assembly includes an overlap groove at one end of the outer wall of the bracket 4. An overlap plate 23 is slidably connected to the inside of the overlap groove. One side of the overlap plate 23 is fixedly connected to the outer wall of the fitting cover 8. A pressure groove is provided on one side of the inner wall of the overlap groove. A pressure block 9 is slidably connected to the inside of the pressure groove. Reset grooves are provided on both sides of the pressure groove inside the bracket 4. A reset block 10 is slidably connected to the inside of the reset groove. The inside of the reset groove communicates with the inside of the pressure groove. Corresponding inclined surfaces are provided on opposite ends of the reset block 10 and the pressure block 9. A movable rod is rotatably connected to the inner wall of the linkage groove between the connecting frame 12 and the first rack 13. The outer wall of the movable rod... One section is fixedly fitted with a gear 14. The side height of the gear 14 is higher than the height of the first rack 13 and the connecting frame 12. A torsion spring 15 is installed between one end of the movable rod and the inner wall of the linkage groove. Limit grooves are opened on both sides of the linkage groove inside the bracket 4. Limit blocks 16 are slidably connected inside the limit grooves. A connecting plate 17 is installed on the other end of the limit block 16. A second rack 18 is installed on the opposite ends of the two sets of connecting plates 17. The second rack 18 meshes with the end of the gear 14 that is higher than the surface of the first rack 13. An extension rod 19 is installed at the bottom end of the connecting plate 17. 9 is slidably connected to bracket 4. A groove is provided inside bracket 4 on one side of the reset groove, and the inner side of the groove communicates with the inner side of the reset groove. Extension rod 19 is slidably connected to the groove, and one end of extension rod 19 extending into the reset groove is fixedly connected to one end of reset block 10. Furthermore, when replacing and assembling the fitting cover 8 and sealing plate 21, the overlapping plate 23 can be inserted into the overlapping groove, causing the pressure block 9 to slide into the pressure groove and contact the reset block 10, so that their inclined surfaces fit together. This pushes the reset block 10 back into the repositioning groove. When the reset block 10 moves, it can drive the extension rod 19 in the groove. The inward movement causes the two sets of connecting plates 17 to move the second rack 18 horizontally, which in turn causes the gear 14 between the two sets of second racks 18 to rotate the movable rod. As the movable rod rotates, it can also cause the torsion spring 15 to retract. After the pressure block 9 is fully pushed in, the reset block 10 is no longer obstructed, and the pressure on the torsion spring 15 also disappears. The torsion spring 15 can then drive the movable rod to reset, causing the gear 14 to rotate together and drive the second rack 18 to move back, allowing the extension rod 19 to drive the reset block 10 to abut against the two ends of the top surface of the pressure block 9. This completes the combination of the sealing plate 21 and the bonding cover 8.

[0028] In this embodiment, as Figure 3 , Figure 4 and Figure 5As shown, a push-pull groove is provided inside the bracket 4 on the other side of the pressure groove. A push-pull column 11 is slidably connected inside the push-pull groove. A linkage groove is provided inside the bracket 4 on one side of the push-pull groove. A connecting frame 12 is installed at one end of the push-pull column 11 extending into the linkage groove. A first rack 13 is installed at one end of the inner wall of the connecting frame 12. One end of the outer wall of the gear 14 is meshed with the first rack 13. A latching groove 5 is provided at the other end of the push-pull column 11. Furthermore, when the fitting cover 8 and the sealing plate 21 are damaged or aged, causing a decrease in sealing effect and requiring maintenance, repair, or replacement, the latching groove 5 at the top of the push-pull column 11 can be used to move it upward. This causes the connecting frame 12 to move the first rack 13 upward, causing the gear 14 to rotate and retract the torsion spring 15 and the movable rod, causing the two sets of second racks 18 meshing on the other end of the outer wall of the gear 14 to rotate, causing the connecting plate 17 and the extension rod 19 to move again. When the extension rod 19 moves, it can cause the reset block 10 to retract back to the inside of the reset groove. At this time, the reset block 10 no longer abuts against the two ends of the pressure block 9, so the bonding cover 8, together with the sealing plate 21 and the side plate 22, can be lifted upward, allowing the overlapping plate 23 to detach from the inside of the overlapping groove. Then, the staff can perform timely maintenance and repair on the removed sealing components or directly replace them with new sealing components.

[0029] The implementation principle of the piercing clamp with good sealing effect in this embodiment is as follows: the torque nut 7 on the torsion bolt 2 causes the water-blocking plate 6 to move the upper insulating shell 1 downward, so that the fitting covers 8 on the two sets of brackets 4 press against the upper and lower ends of the outer wall of the wire. During the compression process, a certain degree of deformation can be performed, allowing the piercing blade 3 to approach the outer wall of the wire and achieve the piercing effect. As the two sets of insulating shells 1 approach each other, the upper insulating shell 1 will also gradually contact and compress the sealing plate 21 to retract, so that one end of the sealing plate 21 is tightly attached to the outer wall of the upper insulating shell 1, thereby achieving a side seal. The effect, combined with the upper and lower end fitting covers 8, further enhances the overall sealing effect of the wire clamp. When replacing and assembling the fitting cover 8 and the sealing plate 21, the overlapping plate 23 can be inserted into the overlapping groove, allowing the pressure block 9 to slide into the pressure groove and contact the reset block 10, so that the two beveled surfaces fit together, causing the reset block 10 to be pushed back into the repositioning groove. When the reset block 10 moves, it can drive the extension rod 19 to move inside the pull groove, causing the two sets of connecting plates 17 to drive the second rack 18 to translate, causing the gear 14 between the two sets of second racks 18 to drive the movable rod to rotate. While the movable rod rotates, it can drive the torsion... Spring 15 retracts, and after the pressure block 9 is fully pushed in, the reset block 10 is no longer obstructed, and the pressure on the torsion spring 15 also disappears. The torsion spring 15 can then drive the movable rod to reset, causing the gear 14 to rotate and drive the second rack 18 to move back, allowing the extension rod 19 to drive the reset block 10 to abut against the two ends of the top surface of the pressure block 9. This completes the combination of the sealing plate 21 and the bonding cover 8. When the bonding cover 8 and the sealing plate 21 are damaged or aged, causing a decrease in sealing effect and requiring maintenance, repair, or replacement, the latching groove 5 at the top of the push-pull column 11 can be used to move it upward, causing the connecting frame 12 to move. The first rack 13 moves upward, causing the gear 14 to rotate and retract the torsion spring 15 and the movable rod, causing the two sets of second racks 18 meshing on the other end of the outer wall of the gear 14 to rotate, driving the connecting plate 17 and the extension rod 19 to move again. When the extension rod 19 moves, it can drive the reset block 10 to retract back into the reset groove. At this time, the reset block 10 no longer abuts against the two ends of the pressure block 9, so the bonding cover 8, together with the sealing plate 21 and the side plate 22, can be lifted upward, allowing the overlapping plate 23 to detach from the inside of the overlapping groove. Then, the staff can perform timely maintenance and repair on the removed sealing components or directly replace them with new sealing components.
