[0002] In fields such as power, communications, data centers, and industrial automation, cable branching is a critical aspect of system cabling. Traditional cable branching methods mainly include piercing clamps, insulated piercing connectors (IPCs), junction boxes, or field-made branch joints. However, the number and specifications of interfaces in traditional junction boxes or patch panels are usually fixed, making it difficult to flexibly adjust to actual needs. When the system requires adding branches or expansion, the entire connection device often needs to be replaced, leading to increased costs and complex construction. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular and scalable branch cable connection box.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a modular expandable branch cable connection box, including a box body, a cover plate slidably connected to the top surface of the box body, a fixing member slidably passing through the outer side of the box body, the fixing member being inserted into the cover plate, two mounting plates symmetrically fixed inside the box body, multiple mutually aligned slots being formed on the opposite surfaces of the two mounting plates, multiple equidistant connectors being snapped between the two mounting plates, a locking block being fixed on each side of the connector, the locking block being snapped into the slot, multiple grooves aligned with the slots being formed on the mounting plates, a limiting member slidably passing through the groove, the limiting member being inserted into the locking block.

[0005] As a further description of the above technical solution: the fixing component includes a pull block that abuts against the outside of the box body. Two T-shaped grooves are symmetrically opened on the top surface of the box body. T-shaped blocks are slidably connected in the T-shaped grooves. The T-shaped blocks are symmetrically fixed to the bottom surface of the cover plate. The inner wall of the T-shaped groove passes through a countersunk hole. A connecting rod is slidably inserted in the countersunk hole. One end of the connecting rod is fixedly connected to the pull block, and the other end is fixedly connected to a positioning pin. A second spring is sleeved on the outer edge of the connecting rod. A blind hole adapted to the positioning pin is opened on the side of the T-shaped block.

[0006] As a further description of the above technical solution: an upwardly inclined groove is formed on the bottom surface of the card block, a positioning groove is formed on the side of the card block, and the fixing member is inserted into the positioning groove.

[0007] As a further description of the above technical solution: the limiting member includes a support plate slidably connected in the groove, a positioning block is horizontally fixed on the side of the support plate, the positioning block slides through the groove and is inserted into the positioning slot, the top surface of the end of the positioning block is provided with a downward inclined slope, a guide plate is fixedly connected to the top surface of the support plate, and a lever is fixedly connected to the top surface of the guide plate.

[0008] As a further description of the above technical solution: two sliding grooves are symmetrically opened on the inner wall of the groove, a slider is slidably connected in the sliding groove, the slider is fixedly connected to the support plate, and a first spring is fixed between the slider and the inner wall of the sliding groove.

[0011] This utility model has the following beneficial effects:

[0012] 1. Compared with existing technologies, this modular expandable branch cable junction box, through its detachable connectors and mounting plate slot structure, allows users to freely increase or decrease the number of branch connectors according to actual needs without replacing the entire junction box, significantly reducing expansion costs and construction complexity. The connector's locking block engages with the slot via a slanted groove, automatically guiding and aligning upon insertion. Combined with the locking of the positioning block by the limiting component, it achieves locking upon insertion, avoiding manual adjustment. The guide wheel and ramp design reduce friction, making the locking block slide more smoothly and improving assembly efficiency. The positioning block and the positioning slot of the locking block are rigidly inserted, and with the preload of the first spring, it prevents the connector from loosening and ensures the stability of the electrical connection.

[0013] 2. Compared with existing technologies, this modular and expandable branch cable junction box has a cover plate that is double-fixed by T-slots and positioning pins, which has strong sealing performance and prevents dust and moisture from entering. The exposed lever design allows manual operation of the limit component, and the connector can be disassembled without tools, which is convenient for maintenance or replacement.

[0025] The fasteners include a pull block 19 that abuts against the outside of the box body 2. Two T-shaped grooves 3 are symmetrically opened on the top surface of the box body 2. T-shaped blocks 6 are slidably connected in the T-shaped grooves 3. The T-shaped blocks 6 are symmetrically fixed on the bottom surface of the cover plate 1. The inner wall of the T-shaped groove 3 passes through a countersunk hole 21. A connecting rod 20 is slidably inserted in the countersunk hole 21.
