[0002] Distribution cabinets are core equipment in power systems used for power distribution, control, protection, and monitoring, and are widely used in industry, commerce, construction, and infrastructure. Their core function is to achieve rational distribution and safe management of electrical energy by integrating switching equipment, protection devices, and measuring instruments. Distribution cabinets contain wiring terminals, which are electrical conductive components that provide fixed electrical connections to external circuits, facilitating the connection, disconnection, and maintenance of wires.

[0003] The wiring terminal structure of existing power distribution cabinets has the following defects in actual use:

[0004] In existing power distribution cabinets, the wiring terminal structure typically uses screwdrivers and threaded screws to fix the wires, and the same screws are required for disassembly. This makes it difficult to quickly insert or remove the wires, resulting in slow efficiency for wire connection and / or disconnection maintenance. Utility Model Content

[0005] To address the technical problem that existing power distribution cabinet terminal structures typically use screwdrivers and threaded screws to fix wires, and also require screwdrivers and threaded screws to remove wires, resulting in slow wire connection and / or disassembly / removal efficiency, this invention provides a quick-plug terminal structure for power distribution cabinets.

[0006] The technical solution adopted by this utility model is: a quick-plug terminal block structure for a power distribution cabinet, including a power distribution cabinet body and a terminal block body. The power distribution cabinet body has an internal mounting frame, and the terminal block body is mounted on the mounting frame. Insertion holes are provided on the top and bottom outer walls of the terminal block body. Quick-plug components are provided on the top and bottom outer walls of the terminal block body. Each quick-plug component includes a quick-plug fixing ring, a movable plug, and a rotating locking block. The movable plug is slidably connected inside the quick-plug fixing ring, and a pull ring extending to the outside of the quick-plug fixing ring is provided on the outer wall of the movable plug. A spring connected to the movable plug is provided on the inner wall of the quick-plug fixing ring. A top rod is provided on one side of the outer wall of the movable plug. A round rod is provided on the inner wall of the quick-plug fixing ring. The rotating locking block is rotatably connected inside the quick-plug fixing ring via a bearing, and the rotating locking block is sleeved on the outside of the round rod. A torsion spring connected to the rotating locking block is provided on the outer wall of the round rod.

[0007] Furthermore, a fixing component is provided at the top and bottom of the outer wall on one side of the terminal block body. The fixing component includes a fixing box, a rotating block, a cavity, and a slot. The fixing box is fixedly installed on the outer wall on one side of the terminal block body.

[0008] Furthermore, the rotating block is rotatably connected inside the fixed box, and connecting rods are provided on the outer walls of two adjacent rotating blocks.

[0009] Furthermore, a second torsion spring is provided on the inner wall of the fixed box, and the other end of the second torsion spring away from the inner wall of the fixed box is connected to the rotating block.

[0010] Furthermore, the cavity is formed inside the rotating block, and a fixed insert is slidably connected inside the cavity, the fixed insert extending to the outside of the rotating block.

[0011] Furthermore, the slot is formed on the outer wall of the mounting bracket, and the fixing block is inserted into the inside of the slot.

[0012] Furthermore, a pull block extending to the outside of the rotating block is provided on the outer wall of one side of the fixed insert, and a spring connected to the fixed insert is provided on the inner wall of the cavity.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a quick-plug component to eliminate the need for screwdrivers or threaded screws to secure wires, enabling rapid insertion and fixation of wires. This also facilitates easy removal and unplugging of wires, thus improving the efficiency of wire connection, removal, and maintenance.

[0015] Secondly, this utility model uses a fixing component. After the rotating block rotates, the elastic force of the spring can push the fixing block, causing the fixing block to be inserted into the mounting bracket, thus achieving the function of quickly fixing the wiring terminals.

[0016] Secondly, this invention utilizes a torsion spring two in the fixing component. The torsional force of the torsion spring two enables the rotating blocks to rotate and adhere to the rear side of the mounting frame. Several rotating blocks can be hung on the mounting frame, which guides the wiring terminals as they slide on the mounting frame. Attached Figure Description

Insertion holes 6 are provided on the top and bottom outer walls of the terminal block body 3. Quick-plug components 4 are provided on the top and bottom outer walls of the terminal block body 3. The quick-plug component 4 includes a quick-plug fixing ring 41, a movable plug block 42, and a rotating locking block 45. The movable plug block 42 is slidably connected to the inner surface of the quick-plug fixing ring 41. The movable insert 42 has a pull ring 43 extending to the outside of the quick-release fixing ring 41 on its outer wall. The quick-release fixing ring 41 has a spring 44 connected to the movable insert 42 on its inner wall. The movable insert 42 has a push rod 48 on one side of its outer wall. The quick-release fixing ring 41 has a round rod 46 on its inner wall. The rotating block 45 is rotatably connected to the inside of the quick-release fixing ring 41 through a bearing. The rotating block 45 is sleeved on the outside of the round rod 46. The round rod 46 has a torsion spring 47 connected to the rotating block 45 on its outer wall.

[0028] In specific implementations, such as Figure 4 and Figure 5 As shown, a fixing component 5 is provided on the top and bottom of the outer wall of one side of the terminal block body 3. The fixing component 5 includes a fixing box 51, a rotating block 52, a cavity 54 and a slot 59. The fixing box 51 is fixedly installed on the outer wall of one side of the terminal block body 3. The fixing component 5 is used to fix the terminal block body 3 on the mounting bracket 2.

[0029] Furthermore, the rotating block 52 is rotatably connected to the inside of the fixed box 51, and connecting rods 53 are provided on the outer walls of two adjacent rotating blocks 52, through which the fixed box 51 can be rotated.

[0030] Furthermore, a second torsion spring 56 is provided on the inner wall of the fixed box 51, and the other end of the second torsion spring 56 away from the inner wall of the fixed box 51 is connected to the rotating block 52. The torsional force of the second torsion spring 56 can drive the rotating block 52 to rotate.

[0031] Furthermore, the cavity 54 is formed inside the rotating block 52, and a fixed insert 55 is slidably connected inside the cavity 54. The fixed insert 55 extends to the outside of the rotating block 52, and the cavity 54 can play a guiding role.

[0032] Furthermore, the slot 59 is located on the outer wall of the mounting bracket 2, and the fixing block 55 is inserted into the inside of the slot 59 to fix the terminal block body 3.

The elastic force of the second spring 58 can push the fixed plug 55 to move.

[0034] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0035] In use, align the rear wall of the terminal block 3 with the mounting bracket 2, release the rotating block 52, and the torsional force of the second torsion spring 56 will cause the rotating block 52 to rotate, making the rotating block 52 adhere to the rear wall of the mounting bracket 2. This allows the terminal block 3 to slide on the mounting bracket 2, facilitating subsequent repositioning of the terminal block. After moving it to the desired installation position, release the pull block 57, and the elastic force of the second spring 58 will push the fixing plug 55 to move, allowing the fixing plug 55 to insert into the slot 59 on the mounting bracket 2, thus fixing the terminal block 3 to the mounting bracket 2. After passing the wire through the quick-release retaining ring 41, insert it into the socket 6. Release the pull ring 43, and the elastic force of the spring 44 can push the movable plug 42 to move and insert into the wire housing. At the same time, when the movable plug 42 moves, it can push the rotating locking block 45 to rotate, so that the rotating locking block 45 is locked into the wire housing. There is no need to use a screwdriver or threaded screw to fix the wire, realizing the function of quick insertion and fixing of the wire. Therefore, it is also more convenient to pull out and remove the wire. This realizes the quick insertion and removal function of the terminal block, which can improve the efficiency of wire insertion and fixing and disassembly and maintenance.
