Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology for special vehicles, specifically a distribution box for special vehicles that facilitates cable management. Background Technology

[0002] During the operation of special vehicles (such as emergency rescue vehicles and communication command vehicles), the distribution box, as a core component of power distribution, directly affects the reliability of the equipment due to the standardized arrangement of its internal cables. Because special vehicles operate under complex conditions (such as frequent vibration and limited space), a disorganized cable arrangement not only increases the difficulty of maintenance during distribution box inspection but also leads to problems such as increased risk of short circuits due to cable wear and increased electromagnetic interference affecting the operation of precision equipment. Therefore, the standardized arrangement of cables within the distribution box is extremely important.

[0003] In order to organize cables, existing distribution boxes have a mounting backplate inside the box. Multiple fixed limiting mounting seats are fixed on the mounting backplate, and mounting support frames with cable routing grooves are fixed on the limiting mounting seats. By classifying and inserting the cables into the limiting slots of the limiting mounting seats and guiding the cable path through the cable routing grooves of the mounting support frames, relatively neat cable arrangement can be achieved.

[0004] However, in existing power distribution boxes, the position and direction of the limit cable slots are completely fixed, and the limit position and installation direction of the limit slots cannot be flexibly adjusted according to the actual cable routing. In the complex working environment of special vehicles, the cable routing is often diverse, and the fixed limit slots cannot meet the needs of flexible wiring.

[0005] Therefore, there is an urgent need for a special vehicle electrical distribution box that facilitates cable management. The limits and routes of cables can be flexibly adjusted according to the actual space size of the distribution box and the cable routing requirements, making cable management more flexible and convenient. Utility Model Content

[0006] The purpose of this utility model is to provide a special vehicle power distribution box that facilitates cable management, so as to solve the problems mentioned in the background art and achieve the purpose of adjusting the cable arrangement and flexibly managing the cables.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A special vehicle electrical distribution box for easy cable management includes a box body. An installation plate is fixedly provided on the inner side wall of the box body. Multiple snap-fit ​​slots are evenly arranged in an array on the installation plate. A cable management assembly is snapped into the snap-fit ​​slots. The cable management assembly includes a base plate and a wire clamp fixed on the front side of the base plate. Two snap-fit ​​plates that move towards or away from each other are movably provided on the back side of the base plate.

[0009] As a further embodiment of this utility model: in order to enable the snap-fit ​​plate to snap into the snap-fit ​​slot, a guide groove is provided on the back of the substrate, and a slide rod is provided in the guide groove along its axial direction. The snap-fit ​​plate is embedded in the guide groove and slidably connected to the slide rod. A spring is sleeved between the two snap-fit ​​plates.

[0010] As a further embodiment of this utility model: to facilitate the removal of the cable management assembly from the snap-fit ​​slot, a pressing block is provided at each end of the guide slot. The first end of the pressing block extends into the guide slot and is fixedly connected to the snap-fit ​​plate, and the second end of the pressing block extends to the outside of the substrate and forms a pressing end.

[0011] As a further embodiment of this utility model: to prevent the cables inside the wire clamp from interfering with the assembly and disassembly of the cable management components, the axial direction of the guide groove is perpendicular to the axial direction of the wire groove of the wire clamp.

[0012] As a further embodiment of this utility model: in order to enable the cable clamp of the cable management component to meet the cable management needs in both the horizontal and vertical directions, the opening contours of the guide groove and the snap-fit ​​groove are the same and both are square.

[0013] As a further embodiment of this utility model: to ensure that the snap-fit ​​plate can be stably snapped into the snap-fit ​​groove, the spring is a compression spring, and its natural length is greater than the axial length of the guide groove.

[0014] As a further embodiment of this utility model: to facilitate the installation of the mounting plate inside the box, multiple ear plates are vertically fixed to the edge of the mounting plate, and the ear plates are fastened to the inner side wall of the box by bolts.

[0015] As a further embodiment of this utility model: to facilitate the maintenance of the distribution box and the installation of cable management components and mounting plates, the box body is provided with a door that can be rotated on the side opposite to the mounting plate.

[0016] As a further embodiment of this utility model: In order to install the distribution box on a special vehicle, the box body has side plates vertically fixed on two opposite outer side walls, the side plates have mounting holes, and the side plates are fastened to the special vehicle by bolts threaded to the mounting holes.

[0017] As a further embodiment of this utility model: to facilitate the installation of electrical equipment inside the enclosure, a back plate is fixedly connected to the back of the mounting plate by a support rod. The back plate has a plurality of threaded holes arranged in an array, and the threaded holes correspond to the positions of the snap-fit ​​slots.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model features a novel structure. Because the snap-fit ​​plates of the cable management assembly can move towards or away from each other within the guide groove, the cable management assembly can snap into or detach from the snap-fit ​​slot. Therefore, the position of the cable management assembly on the mounting plate can be adjusted according to the actual wiring needs, allowing for flexible adjustment of the cable routing. Since the mounting plate is equipped with pressing blocks that fix the snap-fit ​​plates, pressing operations to drive the snap-fit ​​plates to move towards each other are more convenient, allowing for quick assembly and disassembly of the cable management assembly on the mounting plate. Because the guide groove and the snap-fit ​​slot have the same square opening contour, the direction in which the cable management assembly snaps into the snap-fit ​​slot can be adjusted (e.g., rotated 90 degrees), allowing the cable clamp to meet horizontal or vertical cable management requirements.

[0031] Please see Figure 1-7 In this embodiment of the utility model, the special vehicle power distribution box for easy cable management includes a box body 1, such as... Figure 7 As shown, a door 5 is rotatably connected to one side edge of the box body 1. The side of the box body 1 with the door 5 is defined as the front of the box body 1. A side plate 4 is welded on each of the two outer side walls of the box body 1 adjacent to the door 5. The side plate 4 is perpendicular to the surface of the box body 1. Mounting holes 41 are provided at the top and bottom of the side plate 4. Bolts are threaded into the mounting holes 41. The bolts pass through and are threaded into the mounting holes and then threaded into the bolt holes on the special vehicle, so that the box body 1 is securely connected to the special vehicle.

[0032] like Figure 1 and Figure 2 As shown, a mounting plate 2 is fixedly installed on the inner side wall of the enclosure 1 opposite to the enclosure door 5. Two ear plates 22 are provided on each of the vertical edges of the mounting plate 2. Screw holes are provided on the ear plates 22, and bolts are threaded into these holes. These bolts pass through the ear plates 22 and are threaded onto the inner side wall of the enclosure 1, thus fixing the mounting plate 2 to the inner side wall of the enclosure 1. The mounting plate 2 has multiple evenly arranged slots 21 for engaging the cable management assembly 3 and facilitating changes in the installation position of the cable management assembly 3, providing more cable routing options.

[0033] like Figure 2 and Figure 3As shown, the cable management assembly 3 is detachably snapped into the snap-in slot 21. The cable management assembly 3 includes a base plate 31, and the side of the base plate 31 facing the door 5 is defined as its front side. A wire clip 32 is welded to the front side of the base plate 31, and a guide groove 34 is provided on the back side of the base plate 31. The axial direction of the guide groove 34 is perpendicular to the axial direction of the wire groove of the wire clip 32, so that when the pressing block 37 is pressed to drive the snap-in plate 33 to move, the cable in the wire clip 32 will not interfere with the pressing operation.

[0034] A slide rod 35 is welded and fixed inside the guide groove 34. The length direction of the slide rod 35 is consistent with the axial direction of the guide groove 34. The two ends of the slide rod 35 are welded to the two ends inside the guide groove 34, respectively. Two snap-fit ​​plates 33 are slidably connected to the slide rod 35, so that the two snap-fit ​​plates 33 can move relative to each other or away from each other along the length direction of the slide rod 35. The snap-fit ​​end of the snap-fit ​​plate 33 is hook-shaped, and the end of the snap-fit ​​plate 33 away from the snap-fit ​​end is the tail end. The tail end of the snap-fit ​​plate 33 is embedded in the guide groove 34 and the height of the tail end is consistent with the height of the guide groove 34. This allows the snap-fit ​​plate 33 to move only along the length direction of the slide rod 35 in the guide groove 34 without rotating around the axis. The length of the snap-fit ​​section (straight section) of the snap-fit ​​plate 33 extending out of the guide groove 34 is consistent with the groove depth of the snap-fit ​​through groove 21, ensuring that the cable management assembly 3 can be firmly snapped into the snap-fit ​​through groove 21 and preventing loosening.

[0035] A spring 36 is fitted onto the slide rod 35, located between the two snap-fit ​​plates 33. Specifically, the spring 36 is a compression spring, and its natural length is greater than the axial length of the guide groove 34, providing elastic force to cause the two snap-fit ​​plates 33 to move in opposite directions, thus allowing the snap-fit ​​plates 33 to snap into the snap-fit ​​through groove 21. The guide groove 34 has through grooves at both axial ends, with pressing blocks 37 embedded and slidably connected within each through groove. The length of the pressing block 37 in the axial direction of the guide groove 34 is greater than the depth of the through groove, causing the second end of the pressing block 37 to extend beyond the base plate 31 and form a pressing end. The first end of the pressing block 37 extends into the guide groove 34 and is welded to the snap-fit ​​plate 33, allowing the two snap-fit ​​plates 33 to move in opposite directions by pressing the pressing end of the pressing block 37.

[0036] like Figure 6 As shown, four support rods 23 are welded between the back of the mounting plate 2 and the front of the back plate 24. The four support rods 23 are located at the four top corners of the front of the back plate 24. The back plate 24 has a plurality of threaded holes 241 arranged in an array. The threaded holes 241 correspond to the positions of the snap-fit ​​slots 21 on the mounting plate 2, so that the electrical equipment in the distribution box can be installed on the front of the mounting plate 2 through bolts that are threaded to the threaded holes 241 on the back plate 24.

[0037] This utility model features a novel structure and stable operation. In use, the housing 1 is first secured to the special vehicle using bolts that pass through and threadedly connect to the mounting holes 41. Then, the mounting plate 2 is fixed inside the housing 1 using bolts that pass through and threadedly connect to the screw holes on the ear plate 22. Next, the electrical equipment is secured to the front of the mounting plate 2 using bolts threaded to the threaded holes 241, completing the installation and fixing of the electrical equipment. Based on actual wiring and cable management needs, at locations where cables need to be fixed, the pressing blocks 37 on both sides of the cable management assembly 3 are pressed simultaneously, causing the two snap-fit ​​plates 33 to move towards each other along the axial direction of the slide rod 35, thereby securing the cable management assembly 3. When the snap-fit ​​end of the snap-fit ​​plate 33 is inserted into the snap-fit ​​slot 21, and the pressing block 37 is released, the spring force of the spring 36 causes the two snap-fit ​​plates 33 to move in opposite directions, thereby snapping the cable management component 3 into the snap-fit ​​slot 21. At this time, the direction in which the cable management component 3 is snapped into the snap-fit ​​slot 21 can be adjusted according to the cable routing direction, so that the cable management component 3 can meet the cable routing requirements in the horizontal or vertical direction. If there are new requirements for adjusting the cable routing in the future, the cable management component 3 can be removed from the snap-fit ​​slot 21 by pressing the pressing block 37, and the position of the cable management component 3 on the mounting plate 2 can be re-determined and installed according to the requirements, so as to realize flexible adjustment of cable management.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0039] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
