Description

Technical Field

[0001] This utility model relates to the field of high and low voltage cable technology, specifically to an auxiliary tool for making high and low voltage cable joints. Background Technology

[0002] Power engineering involves a series of processes, from initial technical briefings and civil foundation construction to the installation of high and low voltage equipment, power cable laying, cable termination and splicing, electrical testing, and power supply. Among these processes, the termination and splicing of power cables is a crucial step. The quality of the cable terminations directly affects the accuracy and reliability of power supply to various high and low voltage equipment, and is also closely related to the safety of personnel and equipment.

[0003] Currently, the cables we use are mostly YJV-22. The three-phase cores inside are tightly wound due to the outer sheath and steel armor, especially in 150-300 series cables where the cores are thicker, making manual splicing difficult. In the cable splicing process, firstly, the dimensional requirements are extremely strict, directly affecting power supply quality; secondly, the steps of crimping the ends with copper tubing, installing cold-shrinkage stress-relief tubing, and wrapping with insulating tape are time-consuming and labor-intensive, requiring a significant number of personnel.

[0004] Patent document CN217508124U discloses an auxiliary bending tool for high and low voltage cable heads. This tool features multi-faceted bending and adjustable bending angles, allowing for precise control of the bending angle based on site conditions to ensure the cable insulation is not damaged during bending. It is effectively used in connecting high and low voltage cable terminals to circuit breakers, load switches, and other equipment in power stations, switching stations, distribution rooms, meter boxes, and similar locations.

[0005] However, when using this high and low voltage cable head auxiliary bending tool, there is no suitable separating mechanism for separating the intersecting wire ends of high and low voltage cables, which may lead to a decrease in work efficiency. Therefore, it is necessary to propose an auxiliary tool for making high and low voltage cable intermediate joints. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary tool for making high and low voltage cable joints, so as to solve the problem mentioned in the background art that it is impossible to manually separate large cables and phase-misaligned conductors.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary tool for making high and low voltage cable joints, comprising a housing and a handle fixedly connected to the bottom of the housing, wherein an opening and closing mechanism is provided on one side of the housing, and a transmission mechanism is provided inside the handle;

[0008] The opening and closing mechanism includes a pin base, a first support rod, a second support rod, and an end buckle. The pin base is fixedly connected to one side of the outer casing, the first support rod is fixedly connected to one side of the pin base, the second support rod is rotatably connected to one side of the first support rod, and the end buckle is located at one end of the first support rod. This buckle-type cable fixing mechanism is suitable for fixing various cable models. Depending on the cable model, three types of clamps are available: 25-50, 70-120, and 150-240.

[0009] Preferably, the upper and lower ends of the pin base are provided with retractable pins, and the first support rod is fixedly connected to one side of the pin. When the first support rod moves, the pin slides on one side of the pin base, thereby increasing the distance between the two first support rods.

[0010] Preferably, the transmission mechanism includes an electric actuator, a battery, an on / off button, and a wire. The electric actuator is disposed inside the housing, the battery is disposed inside the handle, the on / off button is disposed outside the handle, and the wire is disposed inside the handle.

[0011] Preferably, one end of the second support rod is rotatably connected to one side of the first support rod, and the other end is rotatably connected to one end of the electric actuator. When the electric actuator extends, the two second support rods will rotate at one end of the electric actuator, thereby increasing the included angle between the two second support rods.

[0012] Preferably, the electric actuator, battery, and open / close button are electrically connected via wires. The open / close button controls the circuit's on / off state, providing convenience and easy control of the opening / closing mechanism. The battery is rechargeable, allowing for extended use, and is economical, environmentally friendly, and provides sufficient power for high-power motors. The hand-held handle offers a comfortable grip, facilitates operation, and reduces operational difficulty.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This auxiliary tool for making high and low voltage cable joints uses a splitting mechanism to open the cable phases by opening and closing the support rod. This provides more space for operation, shortens the time required to make cable joints, and allows for the separation of the cable phase cores. This facilitates tasks such as crimping copper tubes at both ends of the cable, installing cold-shrinkage stress-reducing straight tubes, and wrapping insulating tape. The tool also allows for the marking of cable joint dimensions, making the process more intuitive and accurate, reducing cable joint quality defects, and is compatible with various cable models.

[0015] 2. This auxiliary tool for making high and low voltage cable joints can be operated by a single person holding the handle through a transmission mechanism. It is powered by a battery and controls the electric actuator to open and close the support rod by using the open / close button. The hand-held handle is comfortable to use and easy to operate, reducing the difficulty of operation. The rechargeable battery can be used for a long time, is economical and environmentally friendly, and has sufficient power to suit high-power motors. Attached Figure Description

[0018] Please see Figure 1 This utility model provides a technical solution: Example

[0019] An auxiliary tool for making high and low voltage cable joints includes a housing 1 and a handle 3 fixedly connected to the bottom of the housing 1. An opening and closing mechanism is provided on one side of the housing 1.

[0020] The opening and closing mechanism includes a pin base 6, a first support rod 7, a second support rod 8, and an end buckle 9. The pin base 6 is fixedly connected to one side of the outer casing 1. Retractable pins are provided at both the upper and lower ends of the pin base 6. The first support rod 7 is fixedly connected to one side of the pins. When the first support rod 7 moves, the pins slide on one side of the pin base 6, increasing the distance between the two support rods 7. The first support rod 7 is fixedly connected to one side of the pin base 6, and the second support rod 8 is rotatably connected to one side of the first support rod 7. The end buckle 9 is located at one end of the first support rod 7. This buckle-type cable fixing is suitable for fixing various cable types. Depending on the cable type, three types of clamps are available: 25-50, 70-120, and 150-240. The electric actuator 2 is controlled by the opening and closing button 5 to open and close the support rod 7, so that the support can open and close. There are two end clips 9 at the ends of the two sets of support rods 7. After the end clips 9 fix the cable, the cable phases are spread apart by the opening and closing of the support rods 7. After the cable phases are spread apart, there is more space to facilitate the operation and shorten the time for making cable heads. Example

[0021] Based on Embodiment 1, a transmission mechanism is provided inside the handle 3. This mechanism includes an electric actuator 2, a battery 4, an on / off button 5, and a wire 10. The electric actuator 2 is located inside the outer casing 1. One end of a second support rod 8 is rotatably connected to one side of a first support rod 7, and the other end is rotatably connected to one end of the electric actuator 2. When the electric actuator 2 extends, the two second support rods 8 rotate at one end, increasing the angle between them. The battery 4 is located inside the handle 3, the on / off button 5 is located on the outside of the handle 3, and the wire 10 is located inside the handle 3. The electric actuator 2, battery 4, and on / off button 5 are electrically connected via the wire 10. The on / off button 5 controls the circuit's on / off state, providing convenience and easy control of the opening and closing mechanism. The battery 4 is rechargeable, allowing for long-term use, and is economical, environmentally friendly, and has sufficient power for high-power motors. The hand-held handle 3 provides a comfortable grip, is easy to operate, and reduces operational difficulty. Separating the phase conductors of the cable facilitates the crimping of copper tubes at both ends of the cable, the installation of cold-shrink stress straight tubes, and the wrapping of insulating tape.

[0022] Working principle:

[0023] This auxiliary tool is portable and can be operated by a single person holding the handle 3. It is powered by the battery 4, and the opening / closing button 5 controls the electric actuator 2 to open and close the support rods 7. The two sets of support rods 7 have two end clips 9 at their ends. After the end clips 9 secure the cable, the opening and closing of the support rods 7 spreads the cable phases apart, providing more space for easier work and reducing the time required to make cable ends. It can separate the cable phase cores, facilitating copper tube crimping at both ends of the cable, cold-shrinkage stress straight tube installation, and insulating tape wrapping. Furthermore, the dimensions for making cable ends can be marked on the auxiliary tool, making it more intuitive and accurate, and reducing the number of cable end quality defects.
