[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figure 1 - Figure 5This utility model provides an embodiment of a portable cable auxiliary wiring device, including a main junction box housing 2 with a wiring port 1. A protective cover 3 is provided at the upper end of the main junction box housing 2 via a detachable connection mechanism. A transparent observation window 4 is provided on the inner side of the protective cover 3. An insulating support base 5 is fixedly provided in the central area of the bottom of the inner cavity of the main junction box housing 2. A conductor 6 is mounted on the insulating support base 5. A sleeve-type guide structure 7 extending axially is provided on both opposite axial end faces of the conductor 6, and multiple conductors are arranged in an array on each end face of the conductor 6. A puncture needle 8, a conductive puncture needle 8, is located in the inner cavity of the corresponding sleeve-type guide structure 7 and is used to puncture the end of the cable placed in the sleeve-type guide structure 7 to establish a conductive connection. A movable cable fixing unit is provided at the wiring port 1 of the main junction box housing 2. The movable cable fixing unit is used to adjust the clamping and fixing force on the outer periphery of the cable extending into the wiring port 1. A groove 9 is also provided at the bottom of the inner cavity of the main junction box housing 2. A cable locking mechanism and a linear guide mechanism linked to the cable locking mechanism are provided in the groove 9. The cable locking mechanism includes approximately [missing information - likely related to the linear guide mechanism]. The drive unit, which moves downwards, and the clamping unit, which moves along with the drive unit, are used to clamp and lock or unlock the cables placed inside the main junction box housing 2. The main junction box housing 2 serves as the main structure of the entire wiring device. The wiring port 1 on it is used for cable connection. The transparent observation window 4 inside the protective cover 3 is made of high-transparency polycarbonate (PC) or plexiglass, with a light transmittance of over 90%, allowing operators to observe the connection status of the internal cables during device operation without opening the protective cover 3. The insulating support base 5, fixedly installed in the central area of the bottom, is made of engineering plastics with good insulation properties, such as nylon 66 or polytetrafluoroethylene (PTFE). Its insulation resistance can reach more than 10^12Ω, which can effectively isolate the conductor 6 from the main junction box housing 2, prevent leakage and short circuit, and ensure the electrical safety of the device. The conductor 6 installed on the insulating support base 5 is made of metal materials with good conductivity, such as copper or copper alloy, and its resistivity is generally around 1.7×10^-8Ω·m. It is used to realize the conductive connection between cables.A sleeve-type guide structure 7 extending axially on opposite axial end faces of the conductor 6 is used to guide and position the inserted cable, ensuring that the cable can accurately enter the position of the conductive piercing needle 8. Multiple conductive piercing needles 8, arranged in an array on each end face of the conductor 6, adopt a sharp conical structure with a needle tip diameter between 0.5-1.5mm. When the cable is placed inside the sleeve-type guide structure 7, the conductive piercing needle 8 can pierce into the conductor at the cable head, establishing a reliable conductive connection and ensuring smooth current flow. A movable cable fixing unit is used to adjust the clamping and fixing force on the outer periphery of the cable extending into the connection port 1; the clamping force can be adjusted within the range of 5-30N. To accommodate cables of different diameters and materials, ensuring that the cables do not loosen or fall off during wiring and guaranteeing connection stability, the linear guide mechanism constrains and guides the drive unit of the cable locking mechanism, preventing the drive unit from deviating during movement. The drive unit moves linearly by manual operation. When the drive unit moves the clamping part towards the cable, the clamping part applies pressure to the cable placed inside the main junction box housing 2, pressing and locking the cable to prevent displacement or loosening of the cable within the device. When it is necessary to release the lock, the drive unit moves in the opposite direction, moving the clamping part away from the cable, releasing the pressure lock on the cable, facilitating cable installation and removal operations.
[0022] Please see Figure 4 - Figure 5In this embodiment, the fixing unit includes a protrusion 10 integrally formed on the outer wall of the wiring port 1. The protrusion 10 has an internal threaded hole, and a screw 11 is threaded into the internal threaded hole. A knob 12 is fixedly connected to the end of the screw 11. The driving unit includes a bearing seat 13 disposed on the inner wall of the groove 9. A bidirectional lead screw 14 is rotatably connected to the bearing seat 13. The end of the bidirectional lead screw 14 extends to the outside of the main junction box housing 2 and is fixedly connected to a knob 15. A movable seat 16 is threadedly connected to the outer wall of the bidirectional lead screw 14. The clamping unit includes a support rod 17 fixedly connected to the upper surface of the movable seat 16. A clamping block 18 is fixedly connected to the end of the support rod 17 facing the cable. An arc-shaped positioning groove 19 is formed in the clamping block 18. The surface is textured with anti-slip patterns. The linear guide mechanism includes a slide rail 20 mounted on the inner wall of the long side of the groove 9. A slider 21 is slidably connected to the slide rail 20. The end face of the slider 21 is fixedly connected to the side end of the moving seat 16. The protrusion 10 provides an installation base for the screw 11, ensuring the stability of the screw 11 installation and the integrity of the structure. The internal threaded hole in the protrusion 10 can be designed according to actual needs, such as using a metric M6 thread. The depth of the internal threaded hole is generally 15-25mm, used for threaded connection with the screw 11 to realize the adjustment function of the fixing unit. The screw 11 can be axially moved in the internal threaded hole by rotating it. A knob 12 is fixedly attached to the end of the screw 11 for easy manual rotation by the operator. When it is necessary to fix the cable, the operator rotates knob 12 to move screw 11 towards the cable. The end of screw 11 can press against the cable, applying pressure to achieve initial fixation. The clamping force of screw 11 on the cable can generally be adjusted within the range of 5-20N to accommodate cables of different diameters and materials. Bearing seat 13 provides rotational support for the bidirectional lead screw 14, allowing it to rotate stably within the bearing seat 13. The outer wall of the bidirectional lead screw 14 has two different helical threads. When the operator rotates knob 15, it drives the bidirectional lead screw 14 to rotate. According to the thread transmission principle of the bidirectional lead screw 14, when the bidirectional lead screw 14 rotates, the two moving seats 16... The moving base 16 can move synchronously in opposite directions to achieve precise position adjustment and provide power for the movement of the clamping part. The support rod 17 connects and supports the clamping block 18, allowing the clamping block 18 to move together with the moving base 16. The support rod 17 is made of stainless steel. The clamping block 18 is fixed to the end of the support rod 17 facing the cable for final clamping and fixing of the cable. The arc-shaped positioning groove 19 opened in the clamping block 18 can be designed according to the diameter of common cables, for example, the arc is 120°-150°, which can better fit the shape of the cable and improve the stability of clamping. The surface of the arc-shaped positioning groove 19 is provided with anti-slip texture, which adopts cross stripe or dot anti-slip texture, and the depth of the anti-slip texture is 0.The 5-1mm gap increases the friction between the clamping block 18 and the cable, preventing slippage during clamping. The clamping force of the clamping block 18 can reach 20-50N, ensuring the cable is firmly held. The slide rail 20 is made of stainless steel with a smooth surface and low friction coefficient. The slider 21, slidably connected to the slide rail 20, can slide smoothly along the linear direction on the slide rail 20. Through the cooperation of the slide rail 20 and the slider 21, the movement direction of the moving seat 16 is constrained and guided, ensuring that the moving seat 16 can only move linearly along the direction of the slide rail 20, ensuring that the clamping part can accurately clamp the cable, improving clamping accuracy and stability.
[0023] Please see Figure 2 In this embodiment, the connecting mechanism includes a plug 22 integrally fixed to the lower end face of the protective cover 3. The upper end face of the main junction box housing 2 has a slot 23 adapted to the plug 22. The plug 22 is inserted into the slot 23. A magnet is provided on the contact surface between the plug 22 and the slot 23, and the plug 22 and slot 23 are magnetically connected. The cooperation between the plug 22 and the slot 23 achieves the initial positioning and connection between the protective cover 3 and the main junction box housing 2. Generally, the clearance between the plug 22 and the slot 23 is 0.1-0.3mm to ensure the plug 22... 2. The plug 22 can be smoothly inserted into the slot 23 and the connection is tight. The magnet on the contact surface between the plug 22 and the slot 23 can be set as a neodymium iron boron magnet, which has a strong magnetic force of 5-15N. The magnetic connection allows the plug 22 to be stably attracted in the slot 23, preventing the protective cover 3 from easily falling off without human operation, and ensuring the reliability of the connection between the protective cover 3 and the main junction box housing 2. When it is necessary to open the protective cover 3, only a certain external force needs to be applied to overcome the magnetic force, and the plug 22 can be pulled out from the slot 23. The operation is convenient and quick.
[0024] Working principle: When performing cable connection operation, insert the cable to be connected into the connection port 1 of the main junction box housing 2. At this time, the operator manually rotates the first knob 12 to make the screw 11 move axially in the internal thread hole. The screw 11 is pushed towards the cable and abuts against the cable to achieve the initial fixation of the cable.
[0025] After the cable is initially fixed, the cable is guided and positioned by the sleeve-type guide structure 7 on the opposite axial end faces of the conductor 6, ensuring that the cable accurately enters the position of the conductive puncture needle 8. The multiple conductive puncture needles 8 arranged in an array on each end face of the conductor 6 adopt a sharp conical structure. When the cable is placed in the sleeve-type guide structure 7, the conductive puncture needle 8 pierces into the conductor at the head of the cable, establishing a reliable conductive connection and ensuring that the current passes through smoothly.
[0026] Next, the final clamping and locking operation of the cable is carried out. The operator rotates the second knob 15, which drives the bidirectional lead screw 14 to rotate stably in the bearing seat 13. According to the thread transmission principle of the bidirectional lead screw 14, when the bidirectional lead screw 14 rotates, the two moving seats 16 will move synchronously in opposite directions. During the movement of the moving seats 16, the slide rail 20 and the slider 21 cooperate to constrain and guide the movement direction of the moving seats 16, ensuring that the moving seats 16 move in a straight line along the slide rail 20. The moving seats 16 drive the support rod 17 to move, and the clamping block 18 on the support rod 17 moves accordingly. The arc-shaped positioning groove 19 in the clamping block 18 fits the shape of the cable and applies clamping force to the cable, firmly clamping and locking the cable to prevent the cable from shifting or loosening in the device.
[0027] After completing the wiring, cover the protective cover 3 and insert the plug 22 into the slot 23. A tight connection is achieved through magnetic attraction. If it is necessary to release the cable lock for cable disassembly later, rotate the second knob 15 in the opposite direction. The drive unit moves the clamping part away from the cable, releasing the cable clamping lock. Then rotate the first knob 12 in the opposite direction to loosen the screw 11 from fixing the cable, and the cable can be pulled out from the wiring port 1.
[0028] Through the above steps, the conductive puncture needle 8 can accurately pierce into the cable through its sharp conical structure, establishing a stable conductive connection in a convenient and quick manner. At the same time, the movable cable fixing unit can adapt to different cables, solving the problems of traditional wiring relying on tedious manual stripping of wires, low efficiency, and the need for tools to strip the rubber head, which increases the electrician's load and makes operation inconvenient.
