[0040] Example
[0041] The integrated low-voltage wire harness modular wiring device provided in this embodiment, such as Figures 1-5 As shown, the device includes two sets of longitudinally arranged housings 1; wiring assemblies 2 and isolation mechanisms 3 disposed on the sides of the two sets of housings 1 that are close to each other; the wiring assembly 2 includes several partitions 22 that are laterally fixed inside the housing 1, and wiring grooves 21 formed by adjacent partitions 22; the isolation mechanism 3 includes several through holes 31 opened on the housing 1, insert rods 32 that are movably inserted into the through holes 31, and baffles 33 that are fixedly connected to the ends of the insert rods 32; Velcro 60 is provided on both sides of the housing 1.
[0042] The integrated low-voltage wire harness modular wiring device using the above technical solution separates the wiring slots 21 by partition 22 to achieve classified arrangement of wire harnesses; the wire harnesses are fixed by baffle 33 and plug rod 32 to prevent them from being scattered; the set snap-fit component 4 and clamping mechanism 5 realize modular assembly; the set Velcro 60 enhances expandability and neatness.
[0043] Specifically, in this embodiment, snap-fit components 4 are symmetrically arranged on both sides of the housing 1. The snap-fit components 4 include mating plates 41 fixed on both sides of the housing 1 and slots 42 formed inside the mating plates 41. The mating plates 41 and slots 42 provide a basic structure for modular connection, ensuring quick alignment and fixation of the housing 1.
[0044] Specifically, in this embodiment, the snap-fit assembly 4 is equipped with a snap-fit mechanism 5, which includes a U-shaped insert plate 51 that can be inserted laterally. The inner side of the U-shaped insert plate 51 is fixed with an insertion plate 52 that is adapted to the slot 42. The end of the insertion plate 52 is provided with a snap-fit block 53 extending to both sides. The snap-fit block 53 and the slot 42 of the docking plate 41 form a movable snap-fit engagement. The U-shaped insert plate 51 drives the snap-fit block 53 to be snapped into the slot 42 through the elastic insertion plate 52, so as to achieve a stable connection of the housing 1 and prevent it from falling off.
[0045] Specifically, in this embodiment, the outer surface of the U-shaped insert 51 is fixedly connected to the Velcro 60, and the opening direction of the U-shaped insert 51 is perpendicular to the longitudinal axis of the housing 1. The Velcro 60 allows multiple U-shaped inserts 51 to be glued together, supporting multi-module expansion and reducing space occupation.
[0046] Specifically, in this embodiment, the insertion rod 32 is made of an elastic material, and its outer diameter forms an interference fit with the inner diameter of the through hole 31. The baffle 33 is configured with an arc-shaped structure to cover the wire harness. The elastic insertion rod 32 ensures that the baffle 33 tightly fixes the wire harness, and the arc-shaped baffle 33 prevents the wire harness from wearing.
[0047] Specifically, in this embodiment, the partitions 22 are arranged at equal intervals to form standardized wiring channels 21, with the spacing between adjacent wiring channels 21 being 5-15mm. This standardized spacing design can accommodate different wire diameters, improving compatibility and wiring efficiency.
[0048] Specifically, in this embodiment, the surfaces of the housing 1 and the partition 22 are covered with a polyurethane insulating coating with a thickness of 0.2-0.5 mm. The insulating coating prevents interference between wire harnesses and improves the safety and durability of the device.
[0049] Specifically, in this embodiment, the top of the U-shaped insert plate 51 is provided with anti-slip texture, and the bottom is provided with a guide slope that cooperates with the docking plate 41. The anti-slip texture facilitates operation, and the guide slope ensures smooth insertion and reduces assembly resistance.
[0050] Specifically, in this embodiment, the two sets of housings 1 adopt a symmetrical detachable structure, and their docking points are provided with anti-misalignment protrusions and matching grooves. The protrusions and matching grooves prevent the housings 1 from being misaligned, which can ensure the accuracy of modular assembly.
[0051] Specifically, in this embodiment, the Velcro 60 is a double-sided adhesive structure, and its width is adapted to the outer surface of the U-shaped insert 51. The double-sided adhesive design enhances the connection strength between modules, and the adapted width ensures uniform force distribution.
[0052] In summary, the working principle of the integrated low-voltage wire harness modular wiring device provided in this embodiment is as follows:
[0053] 1. Wire harness arrangement and separation
[0054] Low-voltage wire harnesses are classified by type and placed in the wiring grooves 21 of housing 1 respectively. The horizontal partitions 22 achieve physical isolation of different wire groups to avoid cross-connection.
[0055] 2. Wire harness fixing and sealing
[0056] After the wiring is completed, align the insert 32 of the baffle 33 with the through hole 31 on the housing 1, insert and press the wire harness, and use the interference fit between the insert 32 and the through hole 31 to fix the baffle 33 and prevent the wire harness from becoming tangled.
[0057] 3. Housing alignment and snap-fit
[0058] Align the two sets of housings 1 longitudinally to ensure that the mating plates 41 are vertically fitted;
[0059] The U-shaped insert plate 51 is pushed to slide along the docking plate 41. The insert plate 52 is squeezed by the docking plate 41 and undergoes elastic deformation, which drives the end block 53 to be embedded in the slot 42, so as to achieve a stable connection of the shell 1 and prevent separation.
[0060] 4. Modular Expansion and Integration
[0061] The outer surfaces of adjacent U-shaped inserts 51 are glued together by Velcro 60, supporting the lateral expansion of multiple devices to form an integrated cabling system;
[0062] Similar wire harnesses are grouped together in the same wiring tray 21, which further improves the neatness of the wiring and maintenance efficiency.
[0063] Process characteristics
[0064] Modular assembly: The snap-fit component 4 and the clamping mechanism 5 enable quick assembly and disassembly to adapt to different scenario requirements;
[0065] Anti-scattering design: Isolation mechanism 3 and baffle 33 ensure that the wire harness is fixed in an orderly manner;
[0066] Expanded flexibility: The Velcro 60 supports seamless connection of multiple modules, reducing space occupation.
[0067] Technological advantages
[0068] Solve the problems of messy and inefficient wire harnesses in traditional cabling;
[0069] Enhance safety and compatibility through standardized structures (wiring channel spacing, insulating coating);
[0070] The maintenance process has been simplified, and the efficiency of troubleshooting has been greatly improved.
[0071] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
