Description

Technical Field

[0001] The present application relates to the technical field of distribution boxes, and in particular to a distribution box with a cable wear protection function. Background Art

[0002] As an indispensable key component in the power system, the distribution box is responsible for receiving and distributing electric energy. It is compact in design, easy to install, and has unique technical performance and fixed position layout. It can flexibly adapt to various environmental requirements and is widely used in various power facilities. The distribution box integrates complex electrical parameters and wiring systems, and cleverly encapsulates components such as switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet, forming a complete low-voltage distribution system.

[0003] The design of a traditional distribution box usually includes a box body and a door. One side of the door is connected to the edge of the box opening by a hinge, and the other side relies on a conventional lock to achieve a detachable connection with the box body. Inside the box, multiple functional installation chambers are cleverly divided by fixed partitions. These boxes and partitions are mostly made of iron materials through screw connection or welding technology to ensure the stability of the structure. At the same time, wiring holes are carefully opened on the side walls of the box body and partitions to facilitate the smooth connection of external cables and internal cables.

[0004] However, in practical applications, one problem that cannot be ignored is that the box and partition are made of iron materials with high hardness, while the insulation skin on the outer layer of the cable is relatively soft. As time goes by, the insulation skin is easily worn out due to long-term contact with the inner edge of the wiring hole, which may not only affect the electrical performance of the cable, but also cause safety hazards such as short circuit and leakage. There is room for improvement. Summary of the invention

[0005] The purpose of the present application is to provide a distribution box with cable anti-wear function to solve the wear problem of the cable insulation and the inner edge of the wiring hole in the above-mentioned related technology.

[0007] By adopting the above technical solution, when the cable is connected to the electrical equipment installed in the two chambers, the cable is passed through the corresponding elastic protective sleeve. Due to the installation of the elastic rubber plate and the partition plate, the elastic protective sleeve is used to protect the cable, thereby reducing the possibility of the insulation skin on the outer periphery of the cable being worn by the box and the partition plate, and at the same time extending the corresponding service life and reducing the corresponding safety hazards.

[0008] Optionally, a limiting convex plate which is inserted into the communicating opening is fixedly provided on one side of the insulating rubber plate.

[0009] By adopting the above technical solution, due to the installation setting of the limiting protrusion, during the installation process of the insulating rubber plate, the limiting protrusion on the insulating rubber plate is inserted into the connecting opening on the partition plate, and then the insulating rubber plate and the partition plate are detachably fixed, thereby enhancing the installation stability of the insulating rubber plate.

[0010] Optionally, a heat dissipation opening is provided on a vertical side wall of the box body, and a protective cover with an opening downward is fixedly provided on an outer surface of the box body around an edge of the heat dissipation opening.

[0011] By adopting the above technical solution, when the distribution box is used, the combined arrangement of the heat dissipation port and the protective cover not only improves the heat dissipation performance of the distribution box, but also reduces the possibility of external rainwater entering the box.

[0012] Optionally, a guide hole is provided on the insulating rubber plate, a support plate is arranged on one side of the insulating rubber plate, a mounting hole coinciding with the guide hole and a clearance hole coinciding with the wiring hole are provided on the support plate, and a guide fan is embedded on the inner wall of the mounting hole.

[0013] By adopting the above technical solution, due to the combined setting of the support plate and the guide fan, the staff can start the guide fan to accelerate the circulation of gas in the two cavities through the installation holes and the give way holes, thereby improving the circulation of air inside the box and reducing the possibility of high temperature in a certain area inside.

[0017] By adopting the above technical solution, due to the installation arrangement of the sealing plate, the first control component and the second control component, the staff can slide and adjust the sealing plate to make the sealing hole and the vent hole coincide or misaligned, so that the staff can choose whether to block the vent hole according to actual needs and adjust the corresponding heat dissipation performance.

[0018] Optionally, the lower part of the support plate is rotatably connected to the side of the insulating rubber plate, and the upper part of the support plate is detachably connected to the insulating rubber plate, and the guide fan on the support plate can be rotated to the top of the blocking plate; the first control component includes an adjusting rod fixedly arranged on the side of the support plate away from the insulating rubber plate, and a positioning block fixedly arranged on the blocking plate, and a guide slope is arranged on the end edge of the positioning block; as the support plate rotates to a horizontal state, the adjusting rod abuts against the guide slope and pushes the blocking plate to slide, so that the blocking hole and the vent hole coincide with each other.

[0019] By adopting the above technical solution, when the support plate rotates to a horizontal state, the adjusting rod abuts against the guide slope on the positioning block and pushes the sealing plate to slide away from the partition plate, so that the sealing hole and the vent hole overlap. In this state, the guide fan can be started, accelerating the gas outside the box to enter the interior of the box through the vent holes and the sealing holes, thereby further enhancing the heat dissipation performance of the distribution box.

[0021] By adopting the above technical solution, a guide block is used to limit the sliding of the blocking plate. Due to the combination of the limit block and the first compression spring, the blocking plate can slide toward the partition plate under the compression of the first compression spring until the blocking hole and the vent hole are misaligned.

[0024] Optionally, a guiding slope is provided on the edge of the lower end of the vertical rod, and the third control member includes a control rod hinged on the side of the sealing plate away from the partition plate, and the control rod can be rotated and adjusted and fixed; the rotating surface of the control rod is parallel to the bottom side of the box body, and after the control rod is rotated and adjusted, it can slide along the guiding slope with the sealing plate to a state of abutting the lower end surface of the vertical rod.

[0025] By adopting the above technical solution, when the control rod is adjusted to a certain state, the control rod slides along the guide slope with the blocking plate to a state of abutting against the lower end surface of the vertical rod. During this process, the vertical rod moves upward in the vertical direction, thereby causing the locking block to disengage from the locking groove.

Due to the installation of the elastic rubber plate and the partition plate, the elastic protective sleeve is used to protect the cable, thereby reducing the possibility of the insulation skin on the outer periphery of the cable being worn by the box and the partition plate, and at the same time extending the corresponding service life and reducing the corresponding safety hazards.
