Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figure 1 The diagram shows the structure of a cable protection box according to this application. Figure 1 ;reference Figure 2 The diagram shows the structure of a cable protection box according to this application. Figure 2 The cable protection box is located between the mounting base and the high-voltage wire harness connector 200, and the cable protection box includes: a cable protection box body 100; The mounting part 101 is disposed at one end of the cable protection box body 100 and is fixedly connected to the mounting base; The snap-fit ​​part 102 is disposed at the other end of the cable protection box body 100 and snaps into the high-voltage wire harness connector 200.

[0019] The cable guard box, as a critical connection and protection component, is located between the vehicle's mounting base (such as the body sheet metal or battery pack casing) and the high-voltage wiring harness connector 200. The cable guard box includes a cable guard box body 100, which adopts a slot-shaped structure design, comprising a bottom 103 and two sidewalls 104 extending upward along the bottom 103 in a first direction; the first direction is the direction in which the high-voltage wiring harness extends, and the second direction is perpendicular to the first direction. In one specific implementation, such as... Figure 3 As shown, the bottom 103 of the cable protection box body 100 can be approximated as a rectangle, with a pair of opposing long sides and a pair of opposing short sides. The first direction is parallel to the long side of the cable protection box body 100; the second direction is parallel to the short side of the cable protection box body 100. A mounting portion 101 is provided at one end of the cable protection box body 100. This mounting portion 101 is typically designed as a fixed bracket structure with mounting holes 107. There can be one or more mounting holes 107. A secure mechanical connection is achieved with the mounting base via external connectors such as bolts. The mounting portion 101 and the side wall 104 of the cable protection box body 100 are located on the same plane. The mounting portion 101 is fixedly connected to the mounting base, forming a first fixing point, which provides the basic support for the entire structure. A snap-fit ​​portion 102 is provided at the other end of the cable protection box body 100. This snap-fit ​​portion is specifically designed to... Matching the shape of the high-voltage wire harness connector 200, it typically has a specific female snap 108 that can quickly engage with the corresponding male snap 201 on the high-voltage wire harness connector 200. The snap-fit ​​part 102 engages with the high-voltage wire harness connector 200 to form a second fixing point. In this way, the cable protection box body 100, the mounting base, and the high-voltage wire harness connector 200 form an integrated structure. The cable protection box body 100 is also provided with multiple fixing holes 105 for using external connectors, such as cable ties 300, to firmly fix the high-voltage wire harness to the cable protection box body 100, further enhancing vibration uniformity. The bottom 103 and the outer side wall 104 of the cable protection box body 100 are also designed with reinforcing ribs 106, which significantly improves the overall rigidity of the cable protection box body 100.

[0020] In this embodiment, the cable guard box is located between the mounting base and the high-voltage wiring harness connector 200. The cable guard box includes a cable guard box body 100; a mounting part 101, disposed at one end of the cable guard box body 100 and fixedly connected to the mounting base; and a snap-fit ​​part 102, disposed at the other end of the cable guard box body 100 and snap-fitted to the high-voltage wiring harness connector 200. One end of the cable guard box body 100 is connected to the mounting base, and the other end is connected to the high-voltage wiring harness connector 200, forming a two-point fixed integrated structure. This two-point fixed integrated design ensures that the high-voltage wiring harness connector 200 and the cable guard box body 100 maintain consistent amplitude during vehicle operation, effectively eliminating the stress concentration problem caused by asynchronous vibration. This solves the problem of easy damage to the terminals of the high-voltage wiring harness connector 200.

[0021] In another type of cable protection box of this application, the cable protection box is located between the mounting base and the high-voltage wire harness connector 200, and the cable protection box includes: a cable protection box body 100; The mounting part 101 is disposed at one end of the cable protection box body 100 and is fixedly connected to the mounting base; The snap-fit ​​part 102 is disposed at the other end of the cable protection box body 100 and snaps into the high-voltage wire harness connector 200.

[0022] The cable tray body 100 is located between the vehicle mounting base (such as the body sheet metal or battery pack casing) and the high-voltage wiring harness connector 200. The cable tray body 100 adopts a channel-shaped structure design, consisting of a bottom 103 and two side walls 104 extending upwards along a first direction from the bottom 103, forming a complete cable receiving channel. A mounting portion 101 is provided at one end of the cable tray body 100. This mounting portion 101 adopts a fixed bracket structure, and one or more mounting holes 107 are provided through it, allowing for a reliable mechanical connection to the mounting base using fasteners such as bolts. The mounting portion 101 and the side walls 104 of the cable tray body 100 are on the same plane, ensuring effective force transmission and thus forming the basic support point of the entire structure, i.e., the first fixing point. A snap-fit ​​portion 102 is provided at the other end of the cable tray body 100. The snap-fit ​​part 102 adopts a female snap-fit ​​108 structure that matches the shape of the high-voltage wire harness connector 200, enabling a quick and reliable snap-fit ​​connection with the corresponding male snap-fit ​​201 on the high-voltage wire harness connector 200, thereby establishing a second fixing point. Through the synergistic effect of these two fixing points, the cable protection box body 100, the mounting base, and the high-voltage wire harness connector 200 form an integrated structure. To further improve system performance, the cable protection box body 100 is also provided with multiple optimized fixing holes 105. These fixing holes 105 can be used to install fastening devices such as cable ties 300, reliably fixing the high-voltage wire harness to the cable protection box body 100 and ensuring consistent vibration transmission. In addition, reinforcing ribs 106 structures are provided on the exterior of key parts of the bottom 103 and side walls 104 of the cable protection box body 100, significantly improving the overall rigidity of the cable protection box body 100.

[0023] Bolted connections, as a classic type of detachable mechanical connection, primarily consist of a head and a threaded shank. In practical applications, the bolt passes through a pre-drilled hole in the connected parts, and by screwing it onto the nut, a significant axial clamping force is generated between the connected components. This clamping force is then converted into friction between the contact surfaces of the parts, effectively resisting external loads, including vibration, impact, and separation forces. Its detachable nature provides significant convenience for equipment maintenance, commissioning, and component replacement, making it an indispensable basic connection solution in the industrial field.

[0024] In this embodiment, the cable guard box is located between the mounting base and the high-voltage wiring harness connector 200. The cable guard box includes a cable guard box body 100; a mounting part 101, disposed at one end of the cable guard box body 100 and fixedly connected to the mounting base; and a snap-fit ​​part 102, disposed at the other end of the cable guard box body 100 and snap-fitted with the high-voltage wiring harness connector 200. One end of the cable guard box body 100 is connected to the mounting base, and the other end is connected to the high-voltage wiring harness connector 200, forming a two-point fixed integrated structure. This two-point fixed integrated structure ensures that the amplitude of the high-voltage wiring harness connector 200 and the cable guard box body 100 is consistent during vehicle operation, thereby solving the problem of easy damage to the terminals of the high-voltage wiring harness connector 200.

[0025] Reference Figure 3 The diagram shows the structure of a cable protection box according to this application. Figure 3 ;reference Figure 4 The diagram shows the structure of a cable protection box according to this application. Figure 4 In an optional embodiment of this application, the cable protection box body 100 includes a bottom 103 and two sidewalls 104 extending along a first direction of the bottom 103. The bottom 103 and the sidewalls 104 form a groove structure. One end of the groove structure is connected to the high-voltage wire harness connector 200, and the other end is connected to the mounting base.

[0026] The main structure of the cable tray body 100 includes a bottom 103 and two sidewalls 104 extending from the bottom 103 in a first direction, which together form a groove-shaped structure with a continuous, smooth inner surface. This groove-shaped structure provides ample space for the high-voltage wire harness and reliable radial protection. At one end of the groove-shaped structure, namely the mounting portion 101 of the cable tray body 100, the mounting portion 101 is mechanically connected to the mounting base through a fixed bracket structure, forming the first fixed support point. At the other end of the groove-shaped structure, namely the snap-fit ​​portion 102 of the cable tray body 100, a female snap-fit ​​108 is quickly engaged with the male snap-fit ​​201 of the high-voltage wire harness connector 200, forming the second fixed support point. These two fixed points are located at opposite ends of the groove-shaped structure and are interconnected by the rigid structure of the cable tray body 100, forming a stable two-point fixed integrated structure. This design ensures that vibration loads are evenly distributed throughout the system, effectively avoiding stress concentration.

[0027] The cable protection box body 100 of this application embodiment includes a bottom 103 and two sidewalls 104 extending along a first direction of the bottom 103. The bottom 103 and the sidewalls 104 together form a groove structure. One end of the groove structure is connected to the high-voltage wiring harness connector 200, and the other end is connected to the mounting base. The cable protection box body 100 adopts a groove structure formed by the bottom 103 and the two sidewalls 104, and connects the high-voltage wiring harness connector 200 and the mounting base at both ends, thereby forming a stable two-point fixed rigid system. This structure not only significantly improves space utilization and adapts to the layout requirements of narrow spaces such as around the battery pack, but also ensures that the high-voltage wiring harness connector 200 and the cable protection box body 100 move as a whole in the vehicle vibration environment through the two-point fixed integrated structure. This fundamentally eliminates the risk of terminal fretting wear, increased contact resistance, and overheating caused by asynchronous vibration. At the same time, its integrated groove structure also provides a carrier for the wiring harness, greatly improving the connection reliability and durability of the high-voltage wiring harness system.

[0028] In an optional embodiment of this application, the bottom 103 of the cable protection box body 100 is provided with a set of fixing holes for external connectors to pass through to secure the cable harness.

[0029] A set of fixing holes is provided through the bottom 103 of the cable protection box body 100. Each set of fixing holes preferably includes two symmetrically arranged fixing holes 105. These fixing holes 105 are arranged at intervals along the length direction of the bottom 103 and are used for external connectors such as cable ties 300 to pass through, thereby firmly binding and fixing the high-voltage cable harness within the groove-shaped structure of the cable protection box body 100.

[0030] Cable ties, also known as wire ties, cable bundles, or locking straps, are high-efficiency fasteners specifically designed for bundling, securing, and managing cables. Their core feature is a one-way anti-reverse function, ensuring that the binding can only tighten in one direction, preventing backflow and guaranteeing a secure bundle. In addition, releasable cable ties with more flexible designs are also available on the market. In terms of materials, they are mainly divided into metal cable ties (such as stainless steel), suitable for high-temperature, high-strength, or corrosion-resistant environments; and plastic cable ties (such as nylon), widely used due to their good insulation, flexibility, and economy. In the electromechanical, electronics, and automotive manufacturing industries, cable ties are widely used for the organization, securing, and protection of cables and wire harnesses, serving as a key component in ensuring the safety, neatness, and reliability of electrical wiring.

[0031] In this embodiment, the bottom 103 of the cable tray body 100 is provided with a group of fixing holes for external connectors to pass through and secure the wire harness. By using a multi-point fixing method to connect the high-voltage wire harness to the cable tray body 100, it is ensured that the wire harness and the cable tray body 100 maintain synchronous movement in a vibration environment, effectively eliminating relative displacement. Secondly, the symmetrically arranged fixing holes 105 allow the cable ties 300 to apply uniform constraint force, avoiding excessive local stress on the wire harness that could damage the insulation layer. Furthermore, the arrangement of the fixing holes along the first direction of the bottom 103 allows for flexible selection of fixing positions according to the wire harness routing, significantly improving the adaptability and practicality of the product design.

[0032] In an optional embodiment of this application, the fixing hole group is multiple groups, arranged along the first direction of the bottom 103.

[0033] Multiple sets of fixing holes are provided on the bottom 103, and these fixing hole sets are spaced apart along a first direction of the bottom 103. Each set of fixing holes preferably includes two symmetrically arranged fixing holes 105, forming a standard cable tie 300 mounting position. This arrangement along the first direction of the bottom 103 allows for flexible selection of the most suitable fixing position according to the actual routing of the high-voltage wire harness. This design constrains the high-voltage wire harness within the cable box body 100 through multiple fixing points.

[0034] In this embodiment, multiple sets of fixing holes are arranged along a first direction of the bottom 103. These fixing hole sets arranged along the first direction of the bottom 103 are integrally formed with the cable tray body 100. The diameter of the fixing holes 105 matches the size of the standard cable ties 300, ensuring that the cable ties 300 can pass through smoothly and provide reliable fastening force. This arrangement of multiple sets of fixing holes 105 along the first direction of the bottom 103 not only enhances the flexibility of wire harness fixing, but also ensures that the wire harness and the cable tray body 100 can maintain complete vibration consistency in a vibration environment.

[0035] Reference Figure 3 The diagram shows the structure of a cable protection box according to this application. Figure 3 ;reference Figure 5 The diagram shows the structure of a cable protection box according to this application. Figure 5 In an optional embodiment of this application, each group of fixing holes includes two fixing holes 105 disposed along a second direction of the bottom 103.

[0036] Multiple sets of fixing holes are provided on the bottom 103, each set including two fixing holes 105 symmetrically arranged along a second direction of the bottom 103. This symmetrical arrangement of fixing holes 105 allows a single cable tie 300 to pass through both fixing holes 105 simultaneously in a loop, thus forming a complete constraint loop above the wire harness. Compared with single-hole fixing, this double-hole structure provides a more uniform force distribution, preventing the wire harness from twisting or shifting in a vibration environment, and ensuring that the wire harness is always stably constrained at the center of the slot structure.

[0037] Each set of fixing holes in this embodiment includes two fixing holes 105 arranged along the second direction of the bottom 103. The diameter and spacing of the fixing holes 105 are calculated to match the size of the standard cable tie 300, ensuring that the cable tie 300 can pass through smoothly while ensuring sufficient structural strength. This structure of double fixing holes 105 symmetrically arranged along the second direction of the bottom 103 not only enhances the stability of the wire harness fixing, but more importantly, by cooperating with the groove structure of the cable protection box body 100, it ensures that the wire harness can be effectively constrained in all directions, thereby providing an important structural guarantee for achieving the amplitude consistency between the high-voltage wire harness connector 200 and the cable protection box body 100.

[0038] In an optional embodiment of this application, the center line connecting the two fixing holes 105 in each group is perpendicular to the first direction of the cable protection box body 100.

[0039] Each set of fixing holes on the bottom 103 includes two fixing holes 105. The center line connecting these two fixing holes 105 is arranged perpendicular to the first direction of the cable tray body 100, so that the constraint direction of the cable tie 300 is perpendicular to the first direction of the cable tray body 100. When the high-voltage wire harness is subjected to vibration and impact along its axial direction (i.e., the first direction of the cable tray body 100), this arrangement ensures that the constraint force generated by the cable tie 300 is perpendicular to the vibration direction, forming an optimal damping effect and maximally limiting the axial movement of the wire harness within the cable tray. Simultaneously, this perpendicular arrangement ensures that the line connecting the two fixing holes 105 in the same set is perpendicular to the central axis of the channel structure, allowing the cable tie 300 to apply constraint force symmetrically, avoiding wire harness skewing or twisting caused by asymmetrical fixing. This symmetrical constraint method ensures that the wire harness is stably confined to the center position of the channel structure, preventing frictional wear between the wire harness and the side wall 104.

[0040] In this embodiment, the center line connecting the two fixing holes 105 in each group is perpendicular to the first direction of the cable tray body 100. By setting the center line connecting the fixing holes 105 in each group to be perpendicular to the first direction of the cable tray body 100, the direction of the constraint force generated by the cable tie 300 is perpendicular to the axial vibration direction of the wire harness. When the high-voltage wire harness is subjected to vibration excitation along its axial direction, the cable tie 300 can generate the maximum damping effect, effectively suppressing the axial displacement of the wire harness within the cable tray body 100. Simultaneously, this vertical arrangement ensures a symmetrical distribution of constraint force. The symmetrical layout of the two fixing holes 105 relative to the central axis of the channel structure allows the cable tie 300 to apply uniform constraint force to both sides of the wire harness, avoiding wire harness skewing or torsional deformation that may result from asymmetrical fixing. This symmetrical constraint mechanism ensures that the wire harness is always in the center position of the channel structure, preventing frictional wear between the wire harness and the sidewall 104, and ensuring uniform transmission of vibration energy in the system. Furthermore, this arrangement also optimizes stress distribution. By aligning the constraint force perpendicular to the vibration direction, stress concentration at the 300mm fixing point of the cable tie is reduced, improving reliability over long-term use. The symmetrical force distribution also avoids potential damage to the wire harness insulation layer caused by excessive local stress, further ensuring the safety of the high-voltage wire harness system.

[0041] Reference Figure 6 The diagram shows the structure of a cable protection box according to this application. Figure 6 ;reference Figure 7 The diagram shows the structure of a cable protection box according to this application. Figure 7 In an optional embodiment of this application, the outer side of the cable protection box body 100 is provided with reinforcing ribs 106.

[0042] The bottom 103 and the outer surface of the side wall 104 of the cable protection box body 100 are provided with reinforcing ribs 106. These reinforcing ribs 106 are arranged in a grid pattern and are mainly distributed in key stress areas such as the lower surface of the bottom 103 and the outer surface of the side wall 104. The reinforcing ribs 106 and the cable protection box body 100 are integrally molded to form a complete integral structure.

[0043] In this embodiment, the outer side of the cable protection box body 100 is provided with reinforcing ribs 106. First, the reinforcing ribs 106 effectively improve the bending stiffness and torsional stiffness of the cable protection box body 100 by increasing the moment of inertia of the structural section, enabling it to withstand greater external loads. Second, the reasonable layout of the reinforcing ribs 106 evenly disperses local stress, avoids stress concentration, and significantly improves the fatigue life of the cable protection box body 100 under long-term vibration environment. The reinforcing rib structure 106 not only enhances the overall mechanical properties of the cable protection box body 100, but also ensures the consistency of vibration between the high-voltage wire harness connector 200 and the cable protection box body 100 by increasing the structural stiffness.

[0044] In an optional embodiment of this application, the mounting part 101 is provided with a mounting hole 107, which is located in the mounting area of ​​the mounting part 101 near the side wall 104, for an external connector to pass through so as to connect the cable protection box to the mounting base through the external connector.

[0045] At least one mounting hole 107 is provided on the mounting part 101, and these mounting holes 107 are located in the mounting area of ​​the mounting part 101 near the side wall 104. The diameter of the mounting hole 107 is designed to ensure that the bolt can pass through smoothly while providing sufficient contact area to ensure connection stability. The design of the mounting hole 107 not only provides a reliable mechanical connection function, but also ensures the stability of the entire cable box body 100 under vibration environment through its position. The connection point formed by the mounting hole 107 and the bolt serves as the first fixing point.

[0046] In this embodiment, the mounting part 101 is provided with a mounting hole 107, located in the mounting area near the side wall 104. This hole allows an external connector to pass through, connecting the cable guard box to the mounting base. The diameter of the mounting hole 107 is calculated to ensure smooth bolt passage while providing optimal contact area. This design allows the bolt to apply sufficient preload, reliably resisting vibration loads through friction, while avoiding the risk of loosening due to excessive clearance. The optimized placement of the mounting hole 107 enables it to efficiently transmit and disperse mechanical stress, significantly improving the stability and reliability of the overall structure in vibration environments.

[0047] Reference Figure 1 The diagram shows the structure of a cable protection box according to this application. Figure 1 In an optional embodiment of this application, the snap-fit ​​part 102 is provided with a female buckle 108, and the high-voltage wire harness connector 200 is provided with a male buckle 201, and the female buckle 108 and the male buckle 201 are snap-fitted together.

[0048] A female snap-fit ​​108 structure is provided on the snap-fit ​​part 102, and correspondingly, a male snap-fit ​​201 matching the female snap-fit ​​108 is formed on the housing of the high-voltage wire harness connector 200. During assembly, the female snap-fit ​​108 and the male snap-fit ​​201 form a mechanical interlock. This snap-fit ​​structure design creates a rigid connection between the cable protection box body 100 and the high-voltage wire harness connector 200, working in conjunction with the first fixing point at the mounting part 101 as a second fixing point to jointly construct a complete two-point fixing system. This snap-fit ​​method not only provides a reliable mechanical connection but also significantly improves assembly efficiency, allowing for quick installation and fixing of the connector without tools.

[0049] In this embodiment, the snap-fit ​​part 102 is provided with a female snap-fit ​​108, and the high-voltage wire harness connector 200 is provided with a male snap-fit ​​201. The female snap-fit ​​108 and the male snap-fit ​​201 are snapped together. The female snap-fit ​​108 and the male snap-fit ​​201 cooperate to form a reliable mechanical interlocking connection. This connection method ensures that vibration energy can be transmitted synchronously between the cable box body 100 and the high-voltage wire harness connector 200, effectively avoiding terminal wear problems caused by asynchronous vibration. This snap-fit ​​structure adopts a snap-fit ​​design, which significantly improves assembly efficiency. While maintaining excellent vibration performance, this structure also provides appropriate holding force, ensuring connection reliability and taking into account the disassembly during subsequent maintenance. This snap-fit ​​connection serves as the second fixing point of the cable box body, working in conjunction with the first fixing point at the mounting part 101 to form a complete two-point fixing system. This dual fixing design not only enhances the stability of the overall structure but also achieves effective dissipation of vibration energy.
