Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to a quick clamping tool for flexible cable heads. Background Technology

[0002] The core value of live-line splicing leads lies in "uninterrupted power supply work," and they are widely used in scenarios such as power equipment maintenance, line renovation, load adjustment, and emergency repairs. Live-line splicing leads can significantly reduce power outage time, improve power supply reliability, and reduce the impact on social production and residents' lives.

[0003] Currently, when connecting live conductors, workers hold the cable to be connected in one hand and the live conductor in the other. At this time, one hand is at ground potential and the other hand is at 10kV potential, which poses a risk of the worker being drawn into the electric field. Utility Model Content

[0004] The technical problem this invention aims to solve is that when performing live-line splicing of lead wires, there is a potential difference between the cable and the conductor, which poses a risk of workers being drawn into the electric field. The purpose is to provide a flexible cable head quick clamping tool that ensures the cable and conductor are at the same potential when performing live-line splicing of lead wires, thereby preventing workers from being drawn into the electric field and ensuring their safety.

[0005] This utility model is achieved through the following technical solution:

[0006] A flexible cable head quick clamping tool includes a cable clamp, a wire clamp, and a base. The cable clamp includes a fixed cable clamp plate and a movable cable clamp plate, with a return spring disposed between the fixed and movable cable clamp plates. A rotatable first locking handle is disposed on the side of the movable cable clamp plate away from the fixed cable clamp plate. The wire clamp includes a fixed wire clamp plate and a movable wire clamp plate, with a return spring disposed between the fixed and movable wire clamp plates. A rotatable second locking handle is disposed on the side of the movable wire clamp plate away from the fixed wire clamp plate. The cable clamp and the wire clamp are respectively adjustablely connected to both sides of the base.

[0007] The beneficial effects of this utility model are that by adjusting the openings of the cable clamp and the wire clamp to connect to both sides of the base, it is convenient to rotate the first locking handle during operation to drive the movable cable clamp to slide, so that the movable cable clamp and the fixed cable clamp hold the cable clamp, and the movable cable clamp is kept in position under the action of the first locking handle, thereby connecting the head of the cable to the base; and by rotating the second locking handle to drive the movable wire clamp to slide, so that the movable wire clamp and the fixed wire clamp hold the wire clamp, and the movable wire clamp is kept in position under the action of the second locking handle, thereby positioning and connecting the base to the wire, so that the cable (drain wire) and the wire form the same potential. At this time, the operator can touch the wire and cable with both hands to carry out the operation, avoiding the operator being introduced into the electric field and ensuring the safety of the operator.

[0008] In some embodiments, the base is rectangular, the fixed cable clamp is fixedly connected to one end of the base, and the movable cable clamp is slidably connected to the base. The rectangular frame shape of the base provides support and positioning for the cable clamp.

[0009] In some embodiments, the base is provided with a first guide rod and an adjusting screw. The two ends of the first guide rod are respectively connected to the two side walls of the base. Both the movable cable clamp and the fixed cable clamp are slidably connected to the first guide rod. The adjusting screw is sequentially screwed into one side wall of the base, the fixed cable clamp, and the other side wall of the base. By providing the adjusting screw to support and position the fixed cable clamp, and by rotating the adjusting screw to adjust the position of the fixed cable clamp on the adjusting screw, the versatility of the cable clamp is expanded. The first guide rod supports and guides the movable cable clamp, ensuring that it can cooperate with the fixed cable clamp to hold the cable.

[0010] In some embodiments, a second guide rod is further included, with its two ends connected to the two side walls of the base, respectively. The second guide rod, the first guide rod, and the adjusting screw are all parallel. A return spring is fitted on both the first and second guide rods, with its two ends abutting against the clamping sides of the movable cable clamp and the fixed cable clamp, respectively. By making the second guide rod, the first guide rod, and the adjusting screw parallel, the running trajectory of the movable cable clamp is further limited to ensure it can cooperate with the fixed cable clamp to hold the cable. The return springs on both the first and second guide rods facilitate the movement of the movable cable clamp towards the first locking handle under the action of the return spring when the cable is removed, allowing the clamp's jaws to automatically unfold for easier future use and improved cable clamping efficiency.

[0011] In some embodiments, the first locking handle is connected to the side wall of the base by a rivet. The first locking handle includes a circular portion and a handle portion, and the rivet is eccentrically connected to the circular portion. By eccentrically connecting the circular portion of the first locking handle to the rivet, it is convenient to rotate the first locking handle during operation to drive the cable clamp to slide, thereby clamping the cable and maintaining the clamping position under the resistance of the circular portion.

[0012] In some embodiments, the movable cable clamp is provided with a through hole for the adjusting screw to pass through. By providing a through hole for the adjusting screw to pass through in the movable cable clamp, it is easier to prevent the movable cable clamp from sliding when the screw rotates.

[0013] In some embodiments, the fixed conductor clamp is fixedly connected to one end of the base, and the movable conductor clamp is slidably connected to the base. Fixing the fixed conductor clamp to one end of the base facilitates its cooperation with the movable conductor clamp to hold the conductor.

[0014] In some embodiments, a third guide rod is provided on the base, with its two ends respectively connected to the side walls at both ends of the base. The movable wire clamp is slidably connected to the third guide rod. By providing the third guide rod to support and guide the movable wire clamp, it is ensured that it can cooperate with the fixed wire clamp to hold the wire.

[0015] In some embodiments, a vertical plate is connected to the base, and the second locking handle is connected to the vertical plate by a rivet. The second locking handle includes a circular portion, and the rivet and the circular portion form an eccentric connection. By setting the vertical plate to support and position the second locking handle, and by forming an eccentric connection between the circular portion of the second locking handle and the rivet, it is convenient that during operation, rotating the second locking handle will drive the moving wire clamp plate to slide, thereby clamping the wire and maintaining the clamping position under the action of the circular portion.

[0016] In some embodiments, a fourth guide rod is further included, with its two ends connected to the two side walls of the base, and the third guide rod parallel to the fourth guide rod. Both the third and fourth guide rods are fitted with return springs, the two ends of which abut against the clamping sides of the moving conductor clamp and the fixed conductor clamp, respectively. The parallelism of the third and fourth guide rods further limits the movement trajectory of the moving conductor clamp, ensuring it can cooperate with the fixed conductor clamp to hold the conductor. The return springs on both the third and fourth guide rods allow the moving conductor clamp to slide towards the second locking handle under the action of the return springs when the conductor is removed, abutting against the second locking handle, causing the conductor clamp's jaws to open automatically for future use and improving conductor clamping efficiency.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] 1. When connecting live conductors, use cable clamps to hold the cable and conductor clamps to hold the conductor, so that the cable and conductor are at the same potential, to prevent workers from being drawn into the electric field and to ensure the safety of workers.

[0019] 2. The second guide rod, the first guide rod, and the adjusting screw are all parallel to further limit the running trajectory of the moving cable clamp, ensuring that it can cooperate with the fixed cable clamp to hold the cable. A return spring is fitted on both the first guide rod and the second guide rod, so that when the cable is removed, the moving cable clamp can slide towards the first locking handle under the action of the return spring and abut against the first locking handle, so that the clamp jaws of the cable clamp automatically unfold, making it convenient for the next use and improving the efficiency of clamping the cable.

[0020] 3. The third guide rod is parallel to the fourth guide rod, further limiting the running trajectory of the moving wire clamp to ensure that it can cooperate with the fixed wire clamp to hold the wire. Both the third and fourth guide rods are fitted with return springs, so that when the wire is removed, the moving wire clamp can slide towards the second locking handle under the action of the return spring and abut against the second locking handle, so that the clamp jaws of the wire clamp open automatically, making it convenient for the next use and improving the efficiency of clamping the wire.

[0032] Example

[0033] like Figures 1-4As shown, this embodiment provides a quick-clamping tool for flexible cable heads, including a cable clamp, a wire clamp, and a base 30. The cable clamp includes a fixed cable clamp plate 10 and a movable cable clamp plate 11, with a return spring 50 between the fixed cable clamp plate 10 and the movable cable clamp plate 11. A rotatable first locking handle 13 is provided on the side of the movable cable clamp plate 11 away from the fixed cable clamp plate 10. The wire clamp includes a fixed wire clamp plate 20 and a movable wire clamp plate 21, with a return spring 50 between the fixed wire clamp plate 20 and the movable wire clamp plate 21. A rotatable second locking handle 22 is provided on the side of the movable wire clamp plate 21 away from the fixed wire clamp plate 20. The cable clamp and the wire clamp are respectively adjustablely connected to both sides of the base 30. This ensures that the cable (drain wire) and the wire are at the same potential, preventing the operator from being drawn into the electric field when touching the wire and cable with both hands, thus ensuring the operator's safety.

[0034] See Figure 3 and Figure 4 The base 30 is rectangular in shape, the fixed cable clamp 10 is fixedly connected to one end of the base 30, and the movable cable clamp 11 is slidably connected to the base 30. The base 30 is set in a rectangular frame shape to support and position the cable clamp.

[0035] See Figure 3 and Figure 4 The base 30 is provided with a first guide rod 14 and an adjusting screw 40.

The adjusting screw 40 supports and positions the fixed cable clamp 10, and its position can be adjusted by rotating the adjusting screw 40, thus expanding the versatility of the cable clamp. The first guide rod 14 supports and guides the movable cable clamp 11, ensuring it can cooperate with the fixed cable clamp 10 to hold the cable.

[0036] See Figure 3 and Figure 4The system also includes a second guide rod 15, with its two ends connected to the two side walls of the base 30. The second guide rod 15, the first guide rod 14, and the adjusting screw 40 are all parallel. A return spring 50 is fitted onto both the first guide rod 14 and the second guide rod 15, with its two ends abutting against the clamping sides of the moving cable clamp 11 and the fixed cable clamp 10, respectively. By ensuring that the second guide rod 15, the first guide rod 14, and the adjusting screw 40 are all parallel, the running trajectory of the moving cable clamp 11 is further limited to ensure that it can cooperate with the fixed cable clamp 10 to clamp the cable. The return spring 50 fitted onto both the first guide rod 14 and the second guide rod 15 allows the moving cable clamp 11 to slide towards the first locking handle 13 under the action of the return spring 50 when the cable is removed, and to abut against the first locking handle 13, causing the cable clamp's jaws to automatically unfold for easier next use and improving the efficiency of clamping the cable.

[0037] See Figure 3 and Figure 4 The first locking handle 13 is connected to the side wall of the base 30 by rivets. The first locking handle 13 includes a circular portion and a handle portion, and the rivet is eccentrically connected to the circular portion. By eccentrically connecting the circular portion of the first locking handle 13 to the rivet, it is convenient to rotate the first locking handle 13 during operation to drive the cable clamp 11 to slide, thereby clamping the cable and maintaining the clamping position under the resistance of the circular portion.

[0038] See Figure 3 and Figure 4 The moving cable clamp 11 is provided with a through hole for the adjusting screw 40 to pass through. By providing a through hole for the adjusting screw 40 to pass through on the moving cable clamp 11, it is easy to prevent the moving cable clamp 11 from sliding when the screw rotates.

[0039] See Figure 1 and Figure 2 The fixed conductor clamp 20 is fixedly connected to one end of the base 30, and the movable conductor clamp 21 is slidably connected to the base 30. Fixing the fixed conductor clamp 20 to one end of the base 30 facilitates its cooperation with the movable conductor clamp 21 to clamp the conductor.

[0040] See Figure 1 and Figure 2 A third guide rod 23 is provided on the base 30, and the two ends of the third guide rod 23 are respectively connected to the side walls at both ends of the base 30. The movable wire clamp 21 is slidably connected to the third guide rod 23. By setting the third guide rod 23, the movable wire clamp is supported and guided, ensuring that it can cooperate with the fixed wire clamp 20 to clamp the wire.

[0041] See Figure 1 and Figure 2 A vertical plate is connected to the base 30, and the second locking handle 22 is connected to the vertical plate by rivets. The second locking handle 22 includes a circular portion, and the rivet and the circular portion form an eccentric connection. By setting the vertical plate to support and position the second locking handle 22, and by forming an eccentric connection between the circular portion of the second locking handle 22 and the rivet, it is convenient to rotate the second locking handle 22 during operation to drive the moving wire clamp 21 to slide, thereby clamping the wire and maintaining the clamping position under the action of the circular portion.

[0042] See Figure 1 and Figure 2 The system also includes a fourth guide rod 24, with both ends connected to the two side walls of the base 30. A third guide rod 23 is parallel to the fourth guide rod 24. Both the third guide rod 23 and the fourth guide rod 24 are fitted with return springs 50, with both ends of the return springs 50 abutting against the clamping sides of the moving conductor clamp 21 and the fixed conductor clamp 20, respectively. The parallelism of the third guide rod 23 and the fourth guide rod 24 further limits the movement trajectory of the moving conductor clamp 21, ensuring it can cooperate with the fixed conductor clamp 20 to clamp the conductor. The return springs 50 on both the third guide rod 23 and the fourth guide rod 24 allow the moving conductor clamp 21 to slide towards the second locking handle 22 under the action of the return springs 50 when the conductor is removed, abutting against the second locking handle 22, causing the conductor clamp's jaws to open automatically for future use and improving the efficiency of conductor clamping.
