Description

Technical Field

[0001] The invention relates to the technical field of distribution boxes, in particular to a distribution box that is convenient for replacing wiring modules. Background Art

[0002] The wiring module is the core connection component inside the distribution box. It adopts a modular design to integrate multiple electrical connection components to form a fully functional electrical connection unit. This design not only simplifies the wiring process inside the distribution box and improves the wiring efficiency, but also enhances the reliability and maintainability of the circuit. The wiring module usually contains multiple wiring terminals and other electrical connection components. The transparent design of components makes the signal transmission and power supply cleverly integrated, thereby simplifying the wiring process inside the panel.

[0003] When installing wiring terminals in existing distribution boxes, they need to slide multiple groups of wiring terminals one by one from the ends of the terminal row inside the distribution box to the track of the terminal row. After all the wiring terminals are installed, the installers need to firmly install locking pieces at both ends of the wiring module to ensure that the wiring module on the terminal row is firmly fixed. However, due to the large friction between the wiring terminals and the terminal row, it is more difficult for the installers to push the wiring terminals to slide along the terminal row. Secondly, when it is necessary to replace a specific wiring terminal in the wiring module, the installers must first remove the locking piece that fixes the wiring module, and then remove the wiring terminals on one side of the damaged terminal one by one, and finally take out the damaged terminal. This series of steps not only increases the difficulty of operation, but also prolongs the maintenance time. To this end, the present invention provides a distribution box that is convenient for replacing wiring modules. Summary of the invention

The telescopic end is fixedly connected with a connecting plate, and the connecting plate is fixedly connected to the side wall of the clamping plate, the top of the flip assembly is symmetrically fixedly connected with a vertical plate, and a transmission assembly 2 meshing with a threaded assembly is rotatably connected between the two groups of vertical plates, and a mounting frame is fixedly connected to the side wall of the mounting plate, and a fan-shaped gear ring meshing with the second transmission assembly is fixedly connected to the mounting frame. A limiting groove is provided on the side wall of the pressure rod, and a limiting assembly is slidably provided on the side wall of the outer shell, and the fixed end of the limiting assembly abuts against the side wall of the pressure rod. First, align the plug rod at the bottom of the terminal with the slot at the top of the outer shell, and then push the terminal to move it toward the outer shell; in this process, the pressure rod at the top of the outer shell is pushed and naturally slides into the inner cavity of the outer shell. At the same time, the bottom of the pressure rod slides smoothly in the preset sleeve, and the built-in return spring is gradually compressed by the pressure; in addition, the movement of the pressure rod synchronously drives the sliding rod to move downward. During the downward movement of the sliding rod, the sliding rod slides along the track in the preset curved groove. Due to the force generated by the downward movement of the sliding rod, the cylinder rotates accordingly, and the rotation of the cylinder further drives the gear one to rotate. The rotation of the gear one is transmitted through the linkage component, so that the arc block can rotate. As the arc block rotates, the fixing component is pushed and slides into the installation cylinder, thereby realizing the stable fixation of the plug rod and the terminal in the horizontal direction; in this process, the four groups of fixing components cooperate to perform a contraction movement to form a fixed clamping of the plug rod, thereby realizing the stable installation of the terminal;In addition, the downward movement of the pressure rod synchronously drives the support rod to move downward in the vertical direction, and the downward movement of the support rod prompts the rack to move downward accordingly.

Since the transmission component two is meshed with the fan-shaped gear ring, the transmission component two will drive itself to rotate while performing a circular motion. The rotating transmission component two further drives the threaded component to rotate, and the threaded component drives the clamping plate to descend, so that the clamping plate abuts against the top of the L-shaped bracket at the bottom of the terminal. Through this action of the clamping plate, the L-shaped bracket and the terminal are firmly fixed in the vertical direction; wait until the limit groove on the side wall of the pressure rod moves to the same position as the limit groove When the terminal block is in a horizontal position, the pre-set limit assembly is inserted into the limit groove under the action of its inherent elastic force, which is intended to effectively limit and constrain the pressure rod through the limit assembly, thereby preventing the pressure rod from rebounding under the elastic force of the reset spring; when it is necessary to remove the terminal block, it is only necessary to pull the limit assembly to slide it toward the outside of the outer shell, which will cause the limit end of the limit assembly to disengage from the limit groove, thereby releasing the limit constraint on the pressure rod; subsequently, the pressure rod will move upward under the elastic force of the reset spring, pushing the terminal block up, thereby realizing convenient removal of the terminal block; compared with the existing device, the device of the present invention does not need to rely on additional locking members during the installation of the terminal block, and can realize the stable connection of the terminal block. In addition, when removing the terminal block, it is not necessary to remove the terminal block that is still working normally on the side of the damaged terminal block one by one, thereby effectively simplifying the removal process, shortening the time required for removal to a certain extent, and thus improving work efficiency. ;

At the same time, the fixing rod and the fixing clamp are connected to each other. Under the guidance of the fixing rod, the fixing clamp moves into the mounting tube and abuts against the outer surface of the plug rod, so as to achieve the stable fixation of the plug rod and the wiring terminal in the horizontal direction; in this process, the four groups of fixing assemblies cooperate to perform a contraction movement to form a fixed clamping of the plug rod, so as to achieve the stable installation of the wiring terminal; in addition, the non-rigid connection between the fixing clamp and the plug rod is achieved by the provision of the spring 2, which effectively reduces the risk of wear of the fixing clamp on the plug rod.

Since the sixth gear 303 is meshedly connected with the sector gear ring 32, the sixth gear 303 will drive itself to perform a rotational motion while performing a circular motion. The rotating gear 6 303 drives the transmission rod 2 301 to rotate, and the rotating transmission rod 2 301 drives the second bevel gear 302 to rotate.

[0025] Furthermore, the threaded assembly 25 includes a threaded rod 251 rotatably connected to the top of the flip frame 231, a first bevel gear 252 is fixedly connected to the top of the threaded rod 251, an internal threaded tube 253 is threadedly connected to the bottom of the threaded rod 251, and the clamping plate 26 is fixedly connected to the bottom of the internal threaded tube 253, and the rotating second bevel gear 302 drives the first bevel gear 252 to rotate, and the first bevel gear 252 drives the threaded rod 251 to rotate, and the rotating threaded rod 251 drives the internal threaded tube 253 to descend, and the internal threaded tube 253 drives the clamping plate 26 to descend, so that the clamping plate 26 abuts against the top of the L-shaped tripod 5 at the bottom of the terminal 2. Through this action of the clamping plate 26, the L-shaped tripod 5 and the terminal 2 are firmly fixed in the vertical direction. In this process, the telescopic rod 27 is set to limit the descending clamping plate 26.

[0026] Furthermore, the limiting assembly 34 includes a limiting rod 341 slidably arranged on the side wall of the outer shell 4, the limiting rod 341 is fixedly connected to the rod body of the limiting rod 341 with a second circular plate 342, a limiting spring 343 is wound around the rod body of the limiting rod 341, and the limiting spring 343 is connected between the second circular plate 342 and the inner cavity side wall of the outer shell 4. When the limiting groove 33 on the side wall of the waiting pressure rod 7 moves to the same horizontal position as the limiting rod 341, the pre-set limiting rod 341 is inserted into the limiting groove 33 under the elastic force of the limiting spring 343. The purpose is to effectively limit and constrain the pressure rod 7 through the limit rod 341, so as to prevent the pressure rod 7 from rebounding under the elastic force of the reset spring 9; when the terminal 2 needs to be removed, it is only necessary to pull the limit rod 341 to make it slide toward the outside of the outer shell 4, which will cause the limit end of the limit rod 341 to disengage from the limit groove 33, thereby releasing the limit constraint on the pressure rod 7; then, the pressure rod 7 will move upward under the elastic force of the reset spring 9, pushing the terminal 2 up, thereby realizing the convenient disassembly of the terminal 2.

[0027] Working principle: the rotational movement of the flip frame 231 causes the gear six 303 to perform a circular motion. Since the gear six 303 is meshed with the sector gear ring 32, the gear six 303 will drive itself to perform a rotational movement while performing a circular motion. The rotating gear six 303 drives the transmission rod two 301 to rotate, and the rotating transmission rod two 301 drives the second bevel gear 302 to rotate. The rotating second bevel gear 302 drives the first bevel gear 252 to perform a rotational movement. The first bevel gear 252 drives the threaded rod 251 to rotate, and the rotating threaded rod 251 drives the internal threaded cylinder 253 to descend, and the internal threaded cylinder 253 drives the clamping plate 26 to descend, so that the clamping plate 26 abuts against the top of the L-shaped tripod 5 at the bottom of the terminal 2. Through this action of the clamping plate 26, the L-shaped tripod 5 and the terminal 2 are firmly fixed in the vertical direction. In this process, the telescopic rod 27 is provided to limit the descending clamping plate 26. When the limiting groove 33 on the side wall of the pressing rod 7 moves to the same horizontal position as the limiting rod 341, the pre-set limiting rod 341 is inserted into the limiting groove 33 under the elastic force of the limiting spring 343, which is intended to effectively limit and constrain the pressing rod 7 through the limiting rod 341, thereby preventing the pressing rod 7 from rebounding under the elastic force of the reset spring 9; when it is necessary to remove the terminal 2, it is only necessary to pull the limiting rod 341 to slide it toward the outside of the outer shell 4, which will cause the limiting end of the limiting rod 341 to disengage from the limiting groove 33, thereby releasing the limiting constraint on the pressing rod 7; then, the pressing rod 7 will move upward under the elastic force of the reset spring 9, pushing the terminal 2 up, thereby realizing the convenient removal of the terminal 2; Compared with the existing devices, the device in the present invention can achieve a stable connection of the terminal 2 without relying on additional locking parts during the installation of the terminal 2. In addition, when disassembling the terminal 2, there is no need to disassemble the terminal 2 on the side of the damaged terminal 2 that is still working normally one by one, thereby effectively simplifying the disassembly process, shortening the time required for disassembly to a certain extent, and thus improving work efficiency.
