[0002] With the development of cable distribution networks, when independent loads with small capacity are concentrated, cable branch boxes can be used to connect multiple branches of cables. This is because branch boxes cannot be directly operated on each branch. Cable branch boxes are only used as cable branches. The main function of cable branch boxes is to split or transfer cables, mainly serving as cable splitting and transfer functions.

[0003] Currently, Chinese patent CN205846678U discloses a high-safety cable branch box, which includes a branch box housing. A main molded case switch and branch molded case switches are installed inside the housing. The main molded case switch is fixed to a main switch mounting bracket, and the branch molded case switches are fixed to branch switch mounting brackets. The upper terminal of the main molded case switch is connected to the incoming copper busbar, and the lower terminal is connected to the outgoing copper busbar. The lower ends of the outgoing copper busbars are connected to the busbars. The upper terminals of the branch molded case switches are connected to the corresponding busbars via branch busbars. An upper layer of plexiglass protective plate covers the front of the incoming copper busbar, and a lower layer of plexiglass protective plate covers the front of the outgoing copper busbar, busbar, and branch busbar. The left and right sides of the upper and lower plexiglass protective plates are fixed to protective plate mounting brackets, which are then fixed to the branch box housing.

[0004] The aforementioned "cable branch box" can prevent operators from accidentally touching live copper busbars and avoid accidents by installing an acrylic glass protective plate. However, the acrylic glass protective plate is fixedly connected to the protective plate mounting bracket, making it difficult for workers to install, connect, and maintain the copper busbars.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 As shown, an embodiment of the present invention provides a cable branch box for preventing misoperation, comprising a box body 1, a cavity 10 formed within the box body 1, a door 11 hinged to the front side of the box body 1, and a mounting bracket 12 disposed within the cavity 10. The mounting bracket 12 is provided with a connecting copper busbar 13, a main switch 14, and a branch switch 15. Two connecting brackets 2 are correspondingly installed at the front opening end of the cavity 10. Several positioning seats 3 are slidably disposed on the connecting brackets 2. The positioning seats 3 of the left and right connecting brackets 2 are paired and connected to protective glass plates 4. The positioning seats 3 have a locking mechanism for limiting their position.

[0023] In use, two connecting brackets 2 are set up on the left and right sides respectively. Each connecting bracket 2 on both sides is slidably set with a corresponding number of positioning seats 3. A protective glass plate 4 is connected between every two corresponding positioning seats 3 on the left and right sides. In daily use, the protective glass plate 4 can be freely adjusted in position by sliding the positioning seats 3 on both sides in cooperation with the connecting bracket 2. This allows the connecting copper busbar 13, main switch 14 or branch switch 15 to be displayed without removing the protective glass. This makes it convenient for staff to install, wire, and maintain the copper busbar, main switch 14 or branch switch 15, thereby improving the flexibility and practicality of the equipment.

[0024] Both connecting brackets 2 have sliding grooves 20 on their opposite sides. Two baffles 21 are formed at the opening end of the sliding grooves 20. The two baffles 21 and the inner wall of the sliding grooves 20 form a limiting range 22. The positioning seat 3 slides with the connecting brackets 2 and has a limiting block 30 on its inner side that matches the limiting range 22.

[0025] In use, the sliding path of the positioning seat 3 is limited by the cooperation between the limiting interval 22 and the limiting block 30 to prevent the positioning seat 3 from detaching from the connecting bracket 2 during the sliding process;

[0026] Among them, there is a notch between the upper end of the two baffles 21 and the slide groove 20. In daily use, the positioning seat 3 can be slid to the top of the connecting bracket 2 to separate the positioning seat 3 from the connecting bracket 2, which facilitates the daily maintenance and replacement of the positioning seat 3.

[0027] Furthermore, a rotating roller is embedded in the outer wall of the portion of the limiting block 30 located inside the slide groove 20. By setting the rotating roller, the sliding engagement between the limiting block 30 and the slide groove 20 becomes smoother.

[0028] The positioning seat 3 has a U-shaped structure, and an inner side of one of the vertical parts is formed with a receiving hole 31. A locking block 32 is telescopically installed in the receiving hole 31. The outer wall of the connecting bracket 2 is provided with a number of locking holes 23 that are adapted to the locking block 32 at the corresponding position of the receiving hole 31. A sliding hole 33 that communicates with the outer side of the positioning seat 3 is provided in the inner bottom wall of the receiving hole 31. The inner end of the locking block 32 has a sliding rod 34 that extends through to the outside of the through hole. A spring member 35 is sleeved on the outer ring of the sliding rod 34 between the inner bottom wall of the receiving hole 31 and the locking block 32. A toggle member 36 is connected to one end of the sliding rod 34 that extends to the outside of the through hole.

[0029] In use, initially, the locking block 32 extends out of the receiving hole 31 and enters the lock hole 23 due to the force of the spring 35. The locking block 32 and the lock hole 23 lock the position of the positioning seat 3 and the corresponding protective glass plate 4. When it is necessary to adjust the position of the protective glass plate 4, the positioning seat 3 is unlocked. Specifically, the actuating member 36 is rotated upward. As the actuating member 36 rotates upward, it is connected to the slide rod 34, which controls the locking block 32 to retract into the receiving hole 31 against the force of the spring 35. At this time, the limiting lock between the locking block 32 and the lock hole 23 disappears, and the positioning seat 3 is unlocked.

[0030] The positioning seat 3 is fixedly connected to the protective glass plate 4 via connecting rods 40; each positioning seat 3 has two connecting rods 40 and the connecting rods 40 have a first fastening hole 41. The rear side of the protective glass plate 4 is formed with an assembly groove 42 at the corresponding position of each connecting rod 40 and the assembly groove 42 has a second fastening hole 43.

[0031] When using the protective glass plate 4, align the mounting slots 42 on its rear side with the corresponding connecting rods 40 of the positioning seat 3, and then pass the external fasteners (bolts, screws) through the first fastening hole 41 and the second fastening hole 43 to complete the installation and fixing of the protective glass plate 4.

[0032] The assembly slot 42 facilitates the pre-positioning of the protective glass panel 4 during installation, making the assembly of the protective glass panel 4 more convenient.
