Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cable branch boxes, and specifically relates to a quick wiring connection device for cable branch boxes. Background Technology
[0002] In power transmission and distribution systems, cables serve as an important carrier for power transmission. The proper branching and efficient transfer of their lines are one of the key links to ensure the stable operation of the power network. Against this background, cable branch boxes, as a type of power equipment specifically designed for cable branching, have emerged.
[0003] For example, Chinese patent CN222601971U discloses a quick-connection device for cable branch boxes, belonging to the field of cable branch box technology. It includes a box body, with a circuit board fixedly installed inside. Multiple connectors are fixedly installed on the surface of the circuit board. A movable plate is slidably connected inside the box body, and multiple cables are movably connected inside the movable plate. The cables and connectors are in contact with each other. During connection, the cable is inserted into the upper protective cover through the inlet. The cooperation of the movable clamp and the fixed clamp secures the cable. Rotating the turntable causes the threaded rod to rotate, thereby moving the movable plate downwards and allowing the cable inside the upper protective cover to contact the connector, thus completing the connection. This improves the stability of the cable-connection connection and prevents the joint from shifting or falling off under external force, affecting its use.
[0004] The device has some shortcomings that need to be improved. The cable passes through the inlet on the box and then through the through hole on the moving plate. The moving plate is then moved by the rotation of the screw rod driven by the turntable. This process can cause the cable to deviate, the connection is not precise enough, and it is not easy to connect with the terminal. Moreover, once the cable is connected to the terminal, if it becomes loose, it is difficult to detect in time, which affects the safety of the power system operation. Utility Model Content

The insert pins 11 are movably connected to the slots 10. A prompt component 9 is provided on one side of the base box 1, and a fixing component 12 is provided on one side of the guide tube 3.
[0014] refer to Figure 4The adjusting assembly 7 includes a motor 71, which is fixedly connected to the lower side of a fixed plate 8. A lead screw 74 is rotatably connected inside the fixed plate 8, and a screw block 75 is threaded onto the outer surface of the lead screw 74. One side of the screw block 75 is fixedly connected to one side of the top box 2. A drive gear 72 is fixedly connected to the output end of the motor 71, and a driven gear 73 is meshed with one side of the drive gear 72. The driven gear 73 is fixedly connected to the lead screw 74. First limiting grooves 76 are provided on both sides of the interior of the fixed plate 8, and both sides of the screw block 75 are slidably connected to the first limiting grooves 76. The adjusting assembly 7 is configured to... Component 7, motor 71 drives drive gear 72 to rotate, drive gear 72 meshes with driven gear 73, thereby driving lead screw 74 to rotate inside fixed plate 8. Screw block 75 on the outer surface of lead screw 74 is threaded to lead screw 74 and moves axially along lead screw 74 as lead screw 74 rotates. At the same time, the two sides of screw block 75 slide in the first limiting groove 76 of fixed plate 8, thereby driving top box 2 to slide smoothly along fixed plate 8, realizing the adjustment of the position of top box 2, so that the cable on top box 2 is connected to terminal 6 in bottom box 1, ensuring that the cable does not deviate during movement, improving the accuracy of cable and terminal 6 connection, and reducing the difficulty of connection operation.
[0015] refer to Figure 5 The indicator component 9 includes an indicator light 91, which is fixedly connected to both sides of the base box 1. A transmission rod 95 is movably connected inside the slot 10. A slider 94 is fixedly connected to the bottom end of the transmission rod 95. The slider 94 is slidably connected inside the base box 1. A spring is fixedly connected between the slider 94 and the inside of the base box 1. A touch rod 93 is fixedly connected to the bottom end of the slider 94, which is located inside the spring. A touch switch 92 is fixedly connected inside the base box 1. One side of the touch rod 93 movably abuts against one side of the touch switch 92. The touch switch 92 is electrically connected to the indicator light 91. Second limits are provided on both sides of the inside of the base box 1. The slider 94 is slidably connected to the second limiting groove 96 on both sides. By setting the prompt component 9, when the cable connection becomes loose, the position of the top box 2 will change, the insertion post 11 at the bottom of the top box 2 will move in the slot 10 of the bottom box 1, the transmission rod 95 will no longer be compressed, and the slider 94 will slide upward under the action of the spring, thereby driving the touch rod 93 to move away from the touch switch 92, realizing timely warning of loose connection. By setting the second limiting groove 96, the slider 94 moves along the second limiting groove 96 inside the bottom box 1 on both sides, avoiding the slider 94 from deviating or getting stuck during the sliding process, and ensuring the accuracy of the contact between the touch rod 93 and the touch switch 92.
[0016] refer to Figure 2The fixing component 12 includes a screw 121, which is threadedly connected to both sides of the guide tube 3. A torsion wheel 123 is fixedly connected to one side of the screw 121, and an abutment pad 122 is fixedly connected to the side of the screw 121 away from the torsion wheel 123. The abutment pad 122 is movably connected inside the guide tube 3. By setting the fixing component 12, when the cable passes through the guide tube 3, rotating the torsion wheel 123 causes the screw 121 to rotate on both sides of the guide tube 3. Since the screw 121 is threadedly connected to the guide tube 3, the screw 121 will move into the guide tube 3, pushing the abutment pad 122 to make tight contact with the surface of the cable, thereby fixing the cable inside the guide tube 3.
[0017] Operating principle and advantages: First, the cable passes through multiple guide tubes 3 on one side of the top box 2. At this time, the guide tubes 3 can play a preliminary role in organizing and guiding the cable, avoiding multiple cables from becoming tangled and messy, and providing convenience for the subsequent connection terminal 6 work. Next, rotating the torsion wheel 123 drives the screw 121 to move into the guide tube 3, so that the contact pad 122 is in close contact with the cable surface, and the cable is firmly fixed in the guide tube 3, preventing the cable from shaking or shifting during subsequent movement. Then, the motor 71 in the adjustment assembly 7 is started. The output end of the motor 71 drives the drive gear 72 to rotate. The drive gear 72 meshes with the driven gear 73, causing the lead screw 74 to rotate inside the fixed plate 8. The screw block 75 on the outer surface of the lead screw 74 moves along the axial direction of the lead screw 74 due to the threaded connection. At the same time, the two sides of the screw block 75 slide in the first limit groove 76, driving the top box 2 to slide. The automated operation can ensure that the cable moves smoothly. The process is non-displaced, which greatly improves the accuracy of the connection between the cable and the terminal 6 inside the bottom box 1 and reduces the difficulty of the connection operation. During the movement of the top box 2, the bottom post 11 is inserted into the slot 10 at the top of the bottom box 1 to achieve the initial positioning of the top box 2 and the bottom box 1. At the same time, the upper protective cover 4 on the top box 2 is movably connected to the lower protective cover 5 inside the bottom box 1 to form effective protection for the interface and prevent the connection part from being affected by external dust and other factors. After the cable and the terminal 6 are connected, if the top box 2 changes position due to loosening, the post 11 moves in the slot 10, the transmission rod 95 is no longer compressed, and the slider 94 slides upward along the second limit groove 96 under the action of the spring, driving the touch rod 93 away from the touch switch 92, so that the indicator light 91 emits a warning signal, which makes it convenient for the staff to quickly find and deal with the loosening problem and avoid the power system safety hazards caused by the difficulty in detecting loosening in traditional devices.
