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-proof function. Background Art

[0002] As an essential component in power systems, distribution boxes shoulder the heavy responsibility of receiving and distributing electrical energy. Their compact design, easy installation, unique technical features, and fixed-position layout allow them to flexibly adapt to diverse environmental requirements and are widely used in various power facilities. Distribution boxes integrate complex electrical parameters and wiring systems, cleverly enclosing switchgear, measuring instruments, protective devices, and auxiliary equipment within a closed or semi-enclosed metal cabinet, forming a complete low-voltage power distribution system.

[0003] Traditional distribution boxes typically consist of a main body and a door. One side of the door is hinged to the edge of the main body opening, while the other side relies on a conventional lock for removable connection to the main body. Inside the box, fixed partitions cleverly divide the box into multiple functional installation compartments. These boxes and partitions are often constructed of sheet metal, connected by screws or welding, ensuring structural stability. Furthermore, wiring holes are carefully designed on the side walls of the box and partitions to facilitate the smooth connection of external cables and internal cables.

[0004] However, in practical applications, a significant issue is that the box and dividers are made of relatively hard iron, while the cable insulation is relatively soft. Over time, the insulation wears away from prolonged contact with the inner edges of the wiring holes. This can not only affect the cable's electrical performance but also pose safety risks such as short circuits and leakage, leaving room for improvement. Summary of the Invention

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

[0006] The present application provides a distribution box with cable wear protection function, which adopts the following technical solutions:

[0007] A distribution box with cable wear protection function includes a box body and two box doors. A partition plate is fixedly provided in the middle part of the box body in the vertical direction. One side of the box door is hinged to the box body, and the other side of the box body is detachably connected to the partition plate. A connecting opening is provided on the partition plate. An insulating rubber plate for sealing the connecting opening is fixedly provided inside the box body. A plurality of wiring holes are provided on the insulating rubber plate, and an elastic protective sleeve is embedded on the inner wall of the wiring hole.

[0008] 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 on the outer periphery of the cable being worn by the box and the partition plate, while also extending the corresponding service life and reducing the corresponding safety hazards.

[0009] Optionally, a limiting protrusion that is snapped into the communicating opening is fixedly provided on one side of the insulating rubber plate.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] Optionally, a guide hole is provided on the insulating rubber plate, a support plate is provided 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.

[0014] 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.

[0015] Optionally, a plurality of support blocks are fixedly provided on the bottom side of the exterior of the box body, and a plurality of ventilation holes are opened on the bottom side of the box body.

[0016] By adopting the above technical solution, due to the combined arrangement of the support block and the vent hole, the gas outside the box can enter the interior from the bottom side of the box through the vent hole, thereby further enhancing the heat dissipation performance of the distribution box.

[0017] Optionally, a blocking plate is slidably provided on the bottom side of the interior of the box body, and a blocking hole that can overlap with the vent hole is opened on the blocking plate; a first control member that makes the blocking hole and the vent hole overlap and a second offset control member are provided inside the box body.

[0018] By adopting the above technical solution, due to the installation arrangement of the blocking plate, the first control component and the second control component, the staff can slide and adjust the blocking plate so that the blocking hole and the vent hole coincide or are misaligned, so that the staff can choose whether to block the vent hole according to actual needs and adjust the corresponding heat dissipation performance.

[0019] 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, so that 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 fixed on the side of the support plate away from the insulating rubber plate, and a positioning block fixed on the blocking plate, and a guide slope is provided 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.

[0020] 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 blocking plate to slide away from the partition plate, so that the blocking hole and the vent hole coincide with each other. 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 hole and the blocking hole, further enhancing the heat dissipation performance of the distribution box.

[0021] Optionally, a guide block is symmetrically fixed on the bottom side of the interior of the box body, and a guide notch is provided on the guide block for sliding and inserting the blocking plate; the second control component includes a first compression spring in a compressed state and a limit block fixed on the side of the blocking plate, the limit block is located on the side of the guide block away from the partition plate, and the two ends of the first compression spring are fixedly connected to the limit block and the guide block respectively.

[0022] 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.

[0023] Optionally, a horizontal bar for fixing the electrical equipment is detachably installed on the inner wall of the box body away from the door, and a vertical bar is slidably installed in the vertical direction; a locking plate is fixed on the outer periphery of the vertical bar and is located above the horizontal bar, and a locking block is provided on the side of the locking plate facing the horizontal bar, and a locking groove for inserting the locking block is provided on the horizontal bar; a third control part is provided on the blocking plate to drive the vertical bar to move up and down.

[0024] By adopting the above technical solution, when the electrical equipment installed on the cross bar needs to be disassembled and inspected, due to the application setting of the third control component, when the blocking plate is slid, the vertical rod is driven to slide upward by the third control component, and then the locking block is disengaged from the locking groove on the cross bar, thereby releasing the locking state of the cross bar, making it easier to remove the cross bar and the electrical equipment installed on the cross bar as a whole, thereby reducing the difficulty of disassembly and inspection.

[0025] Optionally, a guide 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, 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 guide slope with the sealing plate to a state of abutting the lower end surface of the vertical rod.

[0026] 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 the lower end face 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.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] When the cable is connecting 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 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.

[0047] Example 2:

[0048] Reference Figure 5 and Figure 6 The embodiment of the present application differs from the embodiment 1 in that a guide hole 34 is formed on the insulating rubber plate 3, a support plate 4 is provided on one side of the insulating rubber plate 3, a mounting hole 41 coinciding with the guide hole 34, and a clearance hole 42 coinciding with the wiring hole 32 are formed on the support plate 4, and a guide fan 43 with a small motor is embedded in the inner wall of the mounting hole 41;

[0049] During the operation of the distribution box, the staff can start the guide fan 43 to improve the circulation of air inside the box body 1 and reduce the possibility of a high temperature in a certain area inside.

[0050] Reference Figure 5 and Figure 6 Four support blocks 14 are fixed at the four corners of the bottom side of the outer body 1, and a plurality of ventilation holes 15 are opened on the bottom side of the outer body 1; a blocking plate 5 is slidably provided on the bottom side of the inner body 1, wherein the blocking plate 5 is provided with blocking holes 51 that can overlap with the ventilation holes 15;

[0051] A first control member 16 and a second offset control member 17 are provided inside the box body 1 to make the blocking hole 51 and the vent hole 15 coincide with each other. The staff can choose whether to block the vent hole 15 according to actual needs and adjust the corresponding heat dissipation performance.

[0052] Reference Figure 6 The lower part of the support plate 4 is rotatably connected to the side of the insulating rubber plate 3, and the upper part of the support plate 4 is detachably connected to the insulating rubber plate 3 by a butterfly bolt, and the guide fan 43 on the support plate 4 can be rotated to a horizontal state and is located above the blocking plate 5; the first control component 16 includes an adjustment rod 161 fixedly provided on the side of the support plate 4 away from the insulating rubber plate 3, and a positioning block 162 fixedly provided on the blocking plate 5, and a guide slope 1621 is provided on the end edge of the positioning block 162;

[0053] During the process of the support plate 4 rotating to the horizontal state, the adjusting rod 161 abuts against the guide slope 1621 on the positioning block 162, and pushes the blocking plate 5 to slide away from the partition plate 11, so that the blocking hole 51 and the vent hole 15 coincide with each other. In this state, the guide fan 43 can be started to accelerate the external gas to enter the interior of the box body 1 through the vent hole 15 and the blocking hole 51.

[0054] Reference Figure 6 A guide block 18 is symmetrically fixed on the bottom side of the box body 1, and a guide notch 181 is provided on the guide block 18 for the sliding insertion of the blocking plate 5, so as to limit the sliding process of the blocking plate 5; the second control component 17 includes a first compression spring 171 in a compressed state and a limit block 172 fixed on the side of the blocking plate 5, and the two ends of the first compression spring 171 are fixedly connected to the limit block 172 and the guide block 18 respectively. With this arrangement, under the extrusion of the first compression spring 171, the blocking plate 5 can slide toward the direction close to the partition plate 11.

[0056] Reference Figure 7 , a guiding slope 73 is provided on the edge of the lower end of the vertical rod 7, a locking plate 74 is fixed on the outer periphery of the vertical rod 7 and is located above the cross bar 6, a locking block 75 is provided on the side of the locking plate 74 facing the cross bar 6, and a locking groove 62 for inserting the locking block 75 is provided on the cross bar 6, and a third control member 8 is provided on the blocking plate 5 to drive the vertical rod 7 to move up and down;

[0057] A guide plate 13 for guiding and limiting the vertical rod 7 is fixedly provided on the inner wall of the box body 1, and a receiving plate 71 located below the guide plate 13 is fixedly provided on the outer peripheral surface of the vertical rod 7. A second compression spring 72 is provided in the box body 1 with its two ends fixedly connected to the guide plate 13 and the receiving plate 71 respectively, which is used to squeeze the guide plate 13 and thereby drive the vertical rod 7 to move downward, so that the locking block 75 is inserted into the locking groove 62.

[0058] Reference Figure 7 and Figure 8 The third control member 8 includes a control rod 81 hingedly connected to the side of the blocking plate 5 away from the partition plate 11.

[0059] When the control rod 81 is rotated and adjusted to abut against the second magnetic block 52, the control rod 81 slides along the guide slope 73 with the blocking plate 5 to abut against the lower end surface of the vertical rod 7, thereby causing the vertical rod 7 to move upward in the vertical direction, thereby causing the locking block 75 to disengage from the locking groove 62.

[0060] When the control rod 81 is rotated and adjusted to abut against the third magnetic block 53, the sliding of the blocking plate 5 will not drive the control rod 81 to squeeze the vertical rod 7. In this state, the locking block 75 at the upper end of the vertical rod 7 is inserted into the locking groove 62 on the cross bar 6 under the pressure of gravity and the second compression spring 72.

[0061] The implementation principle of the embodiment of this application is:

In this state, the blocking hole 51 on the blocking plate 5 is offset from the vent hole 15, and the vertical rod 7 slides downward, so that the locking block 75 is inserted into the locking groove 62 on the cross bar 6;

[0063] When the support plate 4 is rotated downward to a horizontal state, the adjustment rod 161 contacts the guide slope 1621 on the positioning block 162, and pushes the blocking plate 5 to slide away from the partition plate 11, so that the blocking hole 51 and the vent hole 15 overlap. In this state, the guide fan 43 can be started to accelerate the external air to enter the interior of the box body 1 through the vent hole 15 and the blocking hole 51;

[0064] When the support plate 4 is in a horizontal state, the control rod 81 is rotated and adjusted to a state of abutment with the second magnetic block 52. The control rod 81 slides along the guide slope 73 with the blocking plate 5 to a state of abutment with the lower end surface of the vertical rod 7. In this process, the vertical rod 7 moves upward in the vertical direction, and the locking block 75 is disengaged from the locking groove 62; thereby, the cross bar 6 can be unlocked.
