[0002] With the development of the cable distribution network, cable branch boxes have been widely used to connect multiple cable branches when independent loads with small capacity are distributed more concentratedly. Because the branch box cannot directly operate each line and is only used as a cable branch, the main function of the cable branch box is to split or transfer the cables.

[0003] Most cable branch boxes are composed of a box body and a cover body. There is only a simple terminal block in the box body, which is then fixed by the terminal screws on the terminal block. When the terminal block is damaged and needs to be disassembled and replaced, the screws need to be tightened one by one before it can be disassembled and replaced, which reduces the efficiency of replacing the terminal block and the practicality of the device. The present application proposes another technical solution to solve this technical problem. Utility Model Content

[0022] The wiring board 2 is provided with cable connection terminals. Meanwhile, the incoming and outgoing cables can adopt independent wiring boards 2. In addition, the incoming and outgoing cables do not need to be crimped with the connection terminals, but can be directly connected to the connection terminals on the wiring board 2.

[0023] The fixing assembly includes a first mounting block 3 and a second mounting block 4 fixedly installed inside the box body 1, a rotating rod 5 is rotatably installed inside the first mounting block 3, a mounting groove is opened inside the first mounting block 3, the rotating rod 5 is rotatably connected to the first mounting block 3 through the mounting groove, the rotating rod 5 rotates with the first mounting block 3 through a bearing, and a connecting plate 6 is fixedly installed on the top of the rotating rod 5. By rotating the rotating rod 5, the connecting plate 6 is driven to rotate synchronously, so that the connecting plate 6 moves to the top of the terminal block 2, which is convenient for limiting and fixing the terminal block 2. When it is moved out from above the connecting plate 6, it is convenient to disassemble the terminal block 2.

[0024] A telescopic spring 7 is fixedly installed at the bottom of the connecting plate 6, a fixed plate 8 is fixedly installed at the bottom of the telescopic spring 7, a clamping block 9 is fixedly installed at the bottom of the fixed plate 8, a clamping groove is provided at the top of the terminal block 2, and the clamping block 9 is clamped with the terminal block 2 through the clamping groove, so that the terminal block 2 can be fixed inside the first mounting block 3, so that the incoming and outgoing cables do not need to be crimped with the terminal terminals, and can be directly connected to the connecting terminals on the terminal block 2.

[0025] A T-shaped pull rod 10 is fixedly installed on the top of the clamping block 9, and an extension hole is opened inside the connecting plate 6. The T-shaped pull rod 10 extends to the outside of the connecting plate 6 through the extension hole, so that the user can pull the T-shaped pull rod 10 to move, thereby achieving the purpose of adjusting the clamping block 9. When the terminal block 2 is damaged, it is convenient to disassemble and replace the terminal block 2, thereby simplifying the disassembly process. There is no need to use tools to remove the bolts one by one and then replace the terminal block 2, thereby simplifying the efficiency of disassembling the terminal block 2.

[0026] It should be noted that the modular low-voltage cable branch box with an input and output line connection mechanism is equipped with a fixed component. When the terminal board 2 is damaged or needs to be replaced, there is no need to use tools to remove the bolts one by one and then replace the terminal board 2, which simplifies the efficiency of disassembling the terminal board 2 and improves the practicality of the device.

[0027] Specifically, when the modular low-voltage cable branch box with an input and output line connection mechanism needs to disassemble and replace the terminal board 2, the T-shaped pull rod 10 is pulled to drive the telescopic spring 7, and the fixed plate 8 is simultaneously driven to move, so that the clamping block 9 moves upward, and the clamping block 9 and the terminal board 2 are released. Then, the connecting plate 6 is driven to rotate by the rotating rod 5, and the connecting plate 6 is moved out from above the terminal board 2, and then the plug-in block 15 and the second mounting block 4 are released. Then, the single damaged terminal board 2 is disassembled from the box body 1 for replacement.

[0028] The moisture-proof component includes two vertical blocks 11 fixedly installed at the bottom of the box body 1, and slide grooves are provided on the opposite sides of the two vertical blocks 11. The slider 13 is slidably connected to the vertical blocks 11 through the slide grooves, and the opposite sides of the two vertical blocks 11 are slidably connected to the mesh frames 12. After the moisture-proof agent in the mesh frame 12 is used for a long time, the internal moisture-proof agent is just replaced to facilitate better moisture-proof treatment of the box body 1, which is beneficial to improve the protection of the device and increase the service life of the internal connecting wires of the device.

[0029] Sliders 13 are fixedly installed on both sides of the mesh frame 12, a box cover 14 is clamped on the top of the mesh frame 12, a plug-in block 15 is fixedly installed on the bottom of the terminal block 2, and a plug-in hole is opened inside the second mounting block 4. The plug-in block 15 is plugged with the second mounting block 4 through the plug-in hole, which is convenient for initially fixing the terminal block 2 on the second mounting block 4 and for subsequently fixing the terminal block 2. There is no need to remove the bolts one by one with the help of tools to replace the terminal block 2, which simplifies the efficiency of disassembling the terminal block 2 and improves the practicability of the device.

[0030] It should be noted that the modular low-voltage cable branch box with an inlet and outlet line connection mechanism can perform moisture-proof treatment on the inside of the box 1 by installing a moisture-proof component, which is beneficial to improving the protection of the device and increasing the service life of the internal connecting wires of the device.

[0031] Specifically, when using the modular low-voltage cable branch box with an inlet and outlet line connection mechanism, the box cover 14 is taken out from the mesh frame 12, and then the moisture-proof agent is poured into the mesh frame 12, and then the box cover 14 is re-covered on the mesh frame 12, and the mesh frame 12 is slid to the inside of the vertical block 11 through the slider 13, and then stably placed inside the box body 1, which can perform moisture-proof treatment on the inside of the box body 1, which is beneficial to improve the protectiveness of the device.

[0032] The working principle of the above embodiment is:

[0033] (1) When the modular low-voltage cable branch box with an inlet and outlet line connection mechanism needs to disassemble and replace the terminal block 2, the T-shaped pull rod 10 is pulled to drive the telescopic spring 7, and the fixed plate 8 is simultaneously driven to move, so that the clamping block 9 moves upward, and the clamping connection between the clamping block 9 and the terminal block 2 is released. Then, the connecting plate 6 is driven to rotate by the rotating rod 5 to move the connecting plate 6 out from above the terminal block 2, and then the plug-in block 15 and the second mounting block 4 are released. Then, the single damaged terminal block 2 is disassembled from the box body 1 for replacement.

[0034] (2) When using the modular low-voltage cable branch box with an inlet and outlet line connection mechanism, the box cover 14 is taken out from the mesh frame 12, and then the moisture-proof agent is poured into the mesh frame 12, and then the box cover 14 is re-covered on the mesh frame 12, and the mesh frame 12 is slid into the inside of the vertical block 11 by the slider 13, and then stably placed in the box body 1, so that the inside of the box body 1 can be treated to be moisture-proof, which is beneficial to improving the protectiveness of the device.
