Description

Technical Field

[0001] This invention relates to the field of power equipment maintenance tools, and in particular to a piercing wiring tool. Background Technology

[0002] Temporary power connections during on-site construction are very common. Currently, these temporary power connections present the following problems: traditional methods, such as stripping wires, require power outages, which is time-consuming and labor-intensive; during temporary connections, the connection points can easily damage the wire cores, creating potential electrical safety hazards on the construction site; after connection, the newly connected lines lack protection against electric shock. While many connectors now have terminals for easy wiring, not all electrical equipment has these terminals. For example, when a user's electricity meter malfunctions, on-site replacement is often required. The standard replacement procedure requires power outages when removing the old meter, which disrupts the customer's normal electricity supply.

[0021] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0022] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0023] Example 1, referring to Figures 1-4 This embodiment provides a piercing and splicing tool. This tool needs to automatically position and clamp the wires to be connected during splicing, facilitate wire piercing and connection for workers, and provide insulation protection for workers. The invention includes an outer sleeve component 1, which is the main load-bearing structure of the device; a positioning component 2 disposed inside the outer sleeve component 1, which clamps and positions the wires to be connected; a piercing needle component 4 disposed inside the positioning component 2; and an inner sleeve component 3 disposed inside the outer sleeve component 1. Figure 1 As shown, the puncture needle component 4 can quickly pass through the outer sheath of the wire to be connected and connect with the conductive metal inside the wire. The inner sleeve component 3 can drive the puncture needle component 4 to puncture the wire. The inner sleeve component 3 needs to be made of insulating material. The positioning component 2 realizes automatic clamping and positioning of the wire to be connected. The inner sleeve component 3 drives the puncture needle component 4 to complete the puncture. There is no need for manual additional fixing of the wire, and the operation process is simplified. The puncture connection does not require stripping the wire. The puncture needle directly penetrates the outer sheath and connects with the internal conductive metal, which greatly reduces the complexity of operation and improves the wiring efficiency. The outer sleeve component 1 includes a load-bearing sleeve 11, which is the main load-bearing structure of this device. The load-bearing sleeve 11 is hollow inside, and a side opening 13 is provided at the bottom of the load-bearing sleeve 11. Figure 2As shown, the side opening 13 facilitates the insertion of the wire into the bottom of the bearing sleeve 11 for clamping and piercing. A V-shaped support 14 is provided at the bottom of the side opening 13. When clamping the wire, the wire to be connected is placed on the V-shaped support 14 for easy positioning, clamping, and piercing. The bearing sleeve 11 needs to be made of insulating material. Both the outer sleeve component 1 (bearing sleeve 11) and the inner sleeve component 3 are made of insulating material, forming an insulating protection system from the operating carrier to the driving component, effectively isolating the current, avoiding the risk of electric shock to the staff, and ensuring operational safety.

[0024] Usage: When connecting wires, hook the bearing sleeve 11 at the bottom of the device to the bottom of the wire through the side opening 13, place the wire on the V-shaped support 14, and then the positioning component 2 will automatically clamp and position the wire on the V-shaped support 14. At this time, rotating the inner sleeve component 3 will push the piercing needle component 4 downward to pierce the outer sheath of the wire to be connected and connect with the conductive metal inside the wire, thus completing the connection. The entire connection method does not require stripping the wire to be connected, making it easy to operate. When maintenance is completed and the connection needs to be disconnected and the device removed, simply rotate the inner sleeve component 3 in the opposite direction to remove the piercing needle component 4 from the inside of the wire, and the device can be removed. Rotating the inner sleeve component 3 in the opposite direction will remove the piercing needle from the wire. The disassembly process and the piercing operation are linked in reverse. The structural design is simple and the operation is reversible. The device is reusable and suitable for multiple wiring and maintenance scenarios.

[0025] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment will specifically describe the positioning method of the positioning component 2 and the puncture method of the puncture needle component 4. The side of the supporting sleeve 11 is provided with a sliding groove 12, and the top of the supporting sleeve 11 is provided with a threaded groove 15, such as... Figure 2 As shown, the groove 12 penetrates the bearing sleeve 11, and the groove 12 is provided on both sides of the bearing sleeve 11.

[0026] The positioning component 2 includes a clamping rod 21 disposed inside the bearing sleeve 11. The clamping rod 21 can slide up and down inside the bearing sleeve 11. The clamping rod 21 can be made of insulating material. A V-shaped clamping groove 22 is provided at the bottom of the clamping rod 21. When it is necessary to clamp and fix the wire to be connected, the V-shaped clamping groove 22 presses the wire under the V-shaped clamping groove 22. The interior of the clamping rod 21 is hollow, and an observation hole 23 is provided on the side of the clamping rod 21. The puncture needle component 4 includes a needle bar 42 disposed inside the clamping rod 21, such as... Figure 4As shown, the needle rod 42 can slide up and down inside the clamping rod 21. The status of the puncture needle can be observed at any time through the observation window. After the puncture needle is inserted into the wire and connected to the circuit, the connection between the needle rod 42 and the wire will inevitably generate heat. If the heat is too high, it may damage the invention. The observation window here can also maintain air circulation and dissipate heat. The observation hole 23 is opened on the side of the clamping rod 21, which can not only observe the puncture status of the puncture needle in real time (such as whether it penetrates the outer skin or whether it contacts the conductive metal), but also facilitate the operator to adjust the operation in time; it can also realize air circulation, quickly dissipate the heat generated when the puncture needle connects with the conductive metal, avoid damage to the device due to overheating, and extend its service life.

[0027] A side support plate 24 is provided on the top of the clamping rod 21. The side support plate 24 is fixedly connected to the clamping rod 21. The side of the side support plate 24 protrudes from the inside of the slide groove 12. A spring 25 is provided on the top of the clamping rod 21. The operator can hold the side support plate 24 from the outside of the bearing sleeve 11 and then drive the clamping rod 21 to rise or fall by manipulating the side support plate 24 to rise or fall.

[0028] The bottom of the needle bar 42 is provided with a pointed needle 41, which extends from the bottom of the V-shaped clamping groove 22, such as... Figure 4 As shown, the needle bar 42 is fixedly connected to the needle tip 41. When the wire is clamped together by the V-shaped clamping groove 22 and the V-shaped support 14, the needle tip 41 will move downward to pierce the outer sheath of the wire and contact the conductive metal inside the wire. The bottom of the clamping rod 21 is provided with a needle sleeve 31V-shaped clamping groove, which forms a "V-shaped clamping" needle sleeve 31 structure with the needle sleeve 31V-shaped support of the bearing sleeve 11. Through the cooperation of the side support plate 24 and the slide groove 12, the operator can manually control the lifting and lowering of the clamping rod 21 to achieve adaptive clamping of wires of different specifications, and the clamping stability is stronger. The setting of the spring 25 enables the clamping rod 21 to have the ability to automatically reset and clamp, simplifying the operation steps while ensuring the clamping force.

[0029] The inner sleeve component 3 includes a needle sleeve 31 disposed on the top of the supporting sleeve 11. The outer wall of the needle sleeve 31 is provided with friction ribs 32, which prevent slippage when the operator rotates the needle sleeve 31. The needle sleeve 31 is the structure for operating the puncture needle component 4 for puncture. A threaded cylinder 33 is disposed at the bottom of the needle sleeve 31, which mates with a threaded groove 15. A wiring cylinder 34 is disposed inside the needle sleeve 31, rotatably connected to the needle sleeve 31. The wiring cylinder 34 can rotate horizontally relative to the needle sleeve 31. The wiring cylinder 34 is hollow inside, and a conductive cylinder 35 is disposed at the bottom of the wiring cylinder 34. A wire is disposed inside the wiring cylinder 34, and the bottom of the wire is connected to the conductive cylinder 35. The conductive cylinder 35 is hollow inside and fixedly connected to the wiring cylinder 34. The conductive cylinder 35 is also hollow inside. The pressure rod 36 and the guide cylinder are made of conductive material. The bottom of the pressure rod 36 is in contact with the spring 25, which is in a compressed state. The bottom of the spring 25 is fixedly connected to the inner wall of the clamping rod 21. The bottom of the pressure rod 36 is fixedly connected to the needle bar 42. The bottom of the conductive cylinder 35 is fixedly connected to the pressure rod 36. The wire is connected to the pressure rod 36 through the conductive cylinder 35. The outer wall of the needle sleeve 31 is provided with friction ridges 32 to increase the friction during rotation, prevent slippage, and improve the torque transmission efficiency during operation. The threaded cylinder 33 and the threaded groove 15 on the top of the bearing sleeve 11 cooperate to convert the rotational motion into the linear lifting motion of the needle sleeve 31. The driving accuracy is high, ensuring the stable downward puncture of the puncture needle. The rotating connection design of the connecting tube 34 and the needle sleeve 31 ensures that the connecting tube 34 remains stationary when the needle sleeve 31 rotates, avoiding the internal wires from getting tangled and ensuring the stability of the circuit connection.

[0030] Usage: When wiring is required, slide the side support plate 24 upwards, causing the clamping rod 21 to slide upwards. Then, hook the device onto the outside of the wire to be connected, with the wire positioned above the V-shaped support 14. Release the side support plate 24, and under the action of the spring 25, the clamping rod 21 will move downwards, pressing the wire onto the V-shaped support 14. The V-shaped clamping groove 22 and the V-shaped support 14 clamp the wire, completing the clamping and positioning of the wire. At this time, rotating the needle sleeve 31 will cause it to slide downwards, driving the conductive cylinder... 35 slides downwards, causing the pressure rod 36 to slide downwards and push the puncture needle downwards, piercing the outer sheath of the wire to be connected. The puncture needle connects with the conductive metal inside the wire, completing the circuit connection. When it is necessary to remove this device, simply rotate the needle sleeve 31 in the opposite direction, causing the needle sleeve 31 to slide upwards, which in turn causes the conductive cylinder 35 to slide upwards. Then, the pressure rod 36 will pull the puncture needle out of the wire. At this time, operate the side support plate 24 to move upwards, causing the clamping rod 21 to move upwards and detach from the wire. At this time, the device can be detached from the wire.

[0031] Example 3, referring to Figures 1-4This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment describes the process of using this device to replace an electricity meter. An indicator light 37 is provided on the outer wall of the wiring sleeve 34. The inside of the indicator light 37 is connected to the wire. When the device is connected to the circuit, the indicator light 37 will light up to remind the staff that the circuit has been connected. The indicator light 37 passes through the needle sleeve 31. The indicator light 37 needs to pass through the needle sleeve 31 to the outer wall of the needle sleeve 31 to remind the staff. The outer wall of the wiring sleeve 34 is provided with an indicator light 37 that passes through the needle sleeve 31, and the indicator light 37 is connected to the internal wire. When the device completes the piercing connection and connects to the circuit, the indicator light 37 will light up automatically. The staff can intuitively judge whether the circuit is successfully connected, avoiding maintenance errors caused by the needle sleeve 31 being "falsely connected", and improving the accuracy of operation.

[0032] Usage: When replacing an electricity meter, the conventional process of removing the old meter requires a power outage. However, this device can be directly connected to the power line to short-circuit the meter, thus maintaining circuit continuity and not affecting the customer's power supply. A temporary meter can also be connected to the wire for power consumption monitoring. This not only avoids disrupting the customer's power supply but also allows for the recording of the customer's power consumption during the replacement process. Utilizing the device's puncture short-circuit function, a temporary short circuit can be achieved without power interruption during meter replacement, ensuring uninterrupted power supply and solving the pain point of traditional meter replacement requiring a power outage. It also supports connecting an external temporary meter for power consumption monitoring during the replacement process, balancing power supply continuity and metering accuracy, expanding the device's application scenarios and enhancing its practical value.

[0033] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
