[0003] In actual use, cable branch boxes are mostly used outdoors. Due to long-term outdoor use and lack of real-time supervision, it is easy to cause internal heat accumulation or cold air to enter under different temperature conditions, which can easily damage the circuit components and cause aging of the cable sheath, affecting normal use. In addition, cable branch boxes are mostly produced in a standardized manner, and the use of internal space lacks freedom. It is not possible to reallocate space according to actual use, which affects effective use. For this reason, we propose a modular cable branch box. Summary of the invention

[0021] As a preferred technical solution of the present application, a filter is provided at the ventilation holes on the outside of the branch box to filter external dust, water vapor, etc., thereby ensuring ventilation effect while reducing the entry of water vapor and dust into the branch box and protecting the effective use of circuit components.

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figure 1-8 , a combined cable branch box, comprising:

[0039] The branch box 1 has an opening on its front side, and a cabinet door 2 is rotatably arranged at the opening. A plurality of vents are evenly arranged on the side of the branch box 1 to facilitate heat exchange.

[0040] The round table 3 is buckled and provided with four groups, and is fixedly installed on one side of the branch box 1;

[0041] The regulating connection component 4 is passed through the other side of the branch box 1, and one end of the regulating connection component 4 is provided with a claw component adapted to the buckled round table 3, which is used for stable connection when adjacent boxes are combined. The end of the regulating connection component 4 extending into the branch box 1 is a T-shaped structure, and both sides of the part of the regulating connection component 4 extending into the branch box 1 are connected with T-shaped blocking plates 9, which are used to control the opening and closing degree of the vents on the side of the branch box 1, thereby realizing the rate of air exchange between the inside of the branch box 1 and the outside;

[0042] A plurality of groups of vertical threading holes are evenly arranged on the back of the branch box 1, and cable threading posts 10 are evenly arranged at the threading holes to facilitate the effective threading of the wire harness during actual use;

[0043] The cable passing column 10 is cylindrical and is provided with a threading hole for threading the wire harness. In actual use, the cable passing column 10 is rotated as needed so that the threading hole faces the inside of the branch box 1. If it is not needed, the direction of the threading hole is adjusted according to the actual temperature conditions, which can assist in regulating the temperature inside the branch box 1.

[0044] A filter screen 5 is provided at the ventilation hole on the outside of the branch box 1 to filter external dust and water vapor, thereby ensuring ventilation effect and reducing water vapor and dust from entering the branch box 1 to protect the effective use of circuit components.

[0045] Reference Figure 5-Figure 6 The regulating connection assembly 4 includes a T-shaped gas storage pipe 41. The T-shaped gas storage pipe 41 is a T-shaped structure and is filled with SF 6 The T-shaped ends of the T-shaped gas storage pipe 41 are both provided with push rods 48 connected to the T-shaped blocking plate 9, so that the T-shaped gas storage pipe 41 is partially located outside the branch box 1 to sense the external temperature change, thereby 6Due to the obvious expansion of gas volume when the temperature rises, the push rod 48 pushes the T-shaped sealing plates 9 on both sides to move, thereby controlling the change in the opening size of the ventilating openings on the sides of the branch box 1. According to the change in external temperature, the rate of ventilation exchange between the inside and outside of the branch box 1 is achieved, thereby achieving the purpose of better temperature control, avoiding internal heat accumulation in summer, difficulty in heat dissipation, and excessive cooling in winter that affects the use of internal circuit components.

[0046] The upper side of the T-shaped gas storage pipe 41 located outside the branch box 1 is connected to an air inlet valve 42, which is convenient for SF inside the T-shaped gas storage pipe 41. 6 The supplement ensures that the connection assembly 4 effectively pushes the T-shaped sealing plate 9 under different temperature environments.

[0047] One end of the T-shaped gas storage tube 41 is fixedly connected to a fixing rod 43, and the end of the fixing rod 43 is connected to a clasp mechanism, which includes a fixing plate 49 coaxially connected to the fixing rod 43, and a plurality of clasp claws 44 are evenly hingedly provided at the outer edge of the fixing plate 49;

[0048] The outer sliding sleeve of the fixed rod 43 is provided with a sliding ring 46, and the outer sleeve of the fixed rod 43 is provided with a spring Ⅰ47 fixedly connected to the T-shaped air storage tube 41, one end of the spring Ⅰ47 is connected to the sliding ring 46, and a hinged push rod 45 is hingedly provided between the sliding ring 46 and each group of buckle claws 44, so that under the action of the spring Ⅰ47 and the hinged push rod 45, the buckle claws 44 can be effectively fastened, so that the buckling table 3 can be stably clamped on the inner side of the buckle claw assembly during the clamping process of the adjacent box bodies, thereby ensuring a stable connection when the box bodies are assembled.

[0049] Reference Figure 1 The buckling table 3 is in the shape of a cone, and the end of the buckling table 3 away from the branch box 1 has a smaller diameter, so it can be easily pushed into the buckling claw mechanism during the splicing process, and it is not easy to fall off after buckling, which effectively facilitates the assembly process and ensures a stable connection.

[0050] Reference Figure 4 A partition plate 8 is fixedly installed on one side of the inner side of the branch box 1 close to the regulating connection component 4, and holes are evenly arranged on the partition plate 8, which effectively facilitates the heat inside the branch box 1 to be conducted out at the holes and dissipated at the vents;

[0051] The inner wall of the branch box 1 on one side close to the buckled truncated table 3 is evenly provided with insertion grooves corresponding to the holes on the partition plate 8, and a telescopic rod assembly 6 is inserted in the insertion groove and the holes, and a frame plate 7 is clamped at the top of the telescopic rod assembly 6, so as to facilitate the adjustment of the internal space during actual use, effectively facilitate the space control of different electrical equipment, and reasonably utilize the internal space.

[0052] Reference Figure 8The telescopic rod assembly 6 includes a main rod body 61, and grooves are provided at both ends of the main rod body 61, and a clamping rod 63 is inserted in the groove. One end of the clamping rod 63 located inside the main rod body 61 is connected to a spring II 62 connected to the inner side of the main rod body 61, thereby effectively ensuring that the entire telescopic rod assembly 6 is in a telescopic state, which is convenient for disassembly and assembly, and greatly facilitates the internal space regulation of the branch box 1;

[0053] A toggle block 64 is fixedly mounted on the side of the clamping rod 63 to facilitate control of the telescopic state of the clamping rod 63 and provide effective convenience for actual adjustment.

[0054] Workflow: In actual use, when splicing and assembly are required, two groups of boxes are spliced ​​adjacent to each other. In the splicing process, the buckling truncated table 3 on the side of one group of boxes is directly plugged into the regulating and connecting component 4 on the other group of boxes. Since the buckling truncated table 3 is truncated, and the diameter of the end close to the regulating and connecting component 4 on the adjacent box is smaller, in the actual plugging process, the curved surface of the buckling truncated table 3 continuously pushes the buckling claw mechanism on the regulating and connecting component 4, so that the buckling claw 44 expands until the buckling truncated table 3 as a whole is inserted into the range of the buckling claw 44. At this time, the buckling claw 44 effectively clamps the buckling truncated table 3 under the action of the spring I 47, the sliding ring 46 and the hinged push rod 45, so as to achieve a stable connection between the two groups of boxes.

[0055] In actual use, when the external temperature changes, the T-shaped gas storage pipe 41 located outside the box body conducts the temperature change, causing the internal SF 6 According to the temperature change, the volume changes accordingly. When the temperature rises, the volume expands, so that the two sets of push rods 48 on the T-shaped gas storage pipe 41 are pushed, and the T-shaped blocking plate 9 connected thereto is pushed, so that the vent is expanded, which effectively facilitates the internal heat dissipation. In hot weather, the internal heat accumulation phenomenon occurs. On the contrary, in cold climates, the gas volume shrinks, and the push rod 48 retracts under the action of air pressure, so that the T-shaped blocking plate 9 covers the vent, preventing excessive cold air from entering the box body, and protecting the effective use of circuit components;

[0056] During the use of the internal space, the adjustable telescopic rod assembly 6 is used in conjunction with the shelf 7 to realize free adjustment of the internal space, so that different components can be placed according to actual needs and the internal space can be reasonably used;

[0057] In actual use, the provision of multiple groups of cable threading columns 10 effectively facilitates the threading of cables and ensures that the threading is carried out in an orderly manner. In addition, the provision of the cable threading columns 10 can also effectively and auxiliaryally adjust the temperature inside the branch box 1.

[0058] Finally, it should be noted that in the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
