A wire harness fixing structure on a backplate

Abstract

This utility model relates to a wire harness fixing structure on a back plate, including a back plate and several wire tubes through which wire harnesses are threaded. A wiring groove is provided on the back of the back plate, and the wire tubes are housed in the wiring groove. The wiring groove is located along the circumferential edge of the back plate. Limiting plates are evenly distributed on the opening of the wiring groove. One end of each limiting plate is a fixed end fixedly connected to the back plate, and the other end is a cantilevered free end. The limiting plates are elastic, and the wire tubes are constrained between the limiting plates and the bottom of the wiring groove. Using the above technical solution, this utility model, through the cooperation of the cantilevered limiting plates and the wiring groove, allows the wire tubes to be directly pressed and embedded into the groove. Simultaneously, the elastic deformation of the limiting plates achieves a snap-fit ​​fixation, eliminating the need for additional tools and bolts. The wire tubes are constrained between the limiting plates and the bottom of the wiring groove, forming a bidirectional limiting and fixing mechanism that can resist vibration or external pulling forces.

Description

Technical Field

[0001] This utility model belongs to the field of furniture decoration technology, and in particular relates to a wire harness fixing structure on a back panel. Background Technology

[0002] In home renovation, securing wiring harnesses is a crucial step in concealed wiring, directly impacting electrical safety, wiring lifespan, ease of future maintenance, and aesthetics. The primary method is to bury the wiring harnesses in conduits within the walls. These conduits protect the wire insulation from scratches and wear from hard, rough materials like bricks and cement inside the walls. The wiring harnesses are then routed to sockets or switches via wall grooves, and the conduits are secured to the wall using clips and screws. This concealed installation method results in a pleasing overall appearance.

[0003] However, due to the difficulty of modifying the route after slotting, and the fact that the plastic conduit may not have enough gripping force on walls with poor strength such as lightweight bricks, hollow bricks, aerated concrete blocks, and old and loose mortar layers, the screws are prone to slipping, loosening, or even breaking and failing to fix the conduit. Fixing by anchors or adhesives is more dependent on material properties and construction precision, and its long-term reliability is insufficient. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a wire harness fixing structure on the back plate, which solves the problem that it is not easy to fix the wires with pipe clips and screws in walls with insufficient strength, and that the fixing by anchor bolts or adhesive is not reliable enough.

[0005] The technical solution of this utility model is as follows: A wire harness fixing structure on a back plate includes a back plate and several wire tubes through which wire harnesses are passed. A wiring groove is provided on the back of the back plate, and the wire tubes are housed in the wiring groove. The wiring groove is provided along the circumferential edge of the back plate. Limiting plates are evenly distributed on the opening of the wiring groove. One end of the limiting plate is a fixed end that is fixedly connected to the back plate, and the other end is a cantilevered free end. The limiting plate is elastic, and the wire tubes are constrained between the limiting plate and the bottom of the wiring groove.

[0006] Using the above technical solution, the conduit can be directly pressed into the groove by the cantilevered limiting plate in conjunction with the wiring groove. At the same time, the elastic deformation of the limiting plate is used to achieve a snap-fit ​​fixation, without the need for additional tools and bolts. The conduit is constrained between the limiting plate and the bottom of the wiring groove, forming a bidirectional limiting fixation of the conduit, which can resist vibration or external pulling force. Moreover, this structure only requires the limiting plate to have a certain degree of elasticity, and it is suitable for various types of conduits, including PVC or metal conduits.

[0007] A further feature of this invention is that the wall surface of the wiring groove opposite the free end of the limiting plate has a recessed structure, and the bottom of the groove corresponding to the limiting plate has an observation hole that connects to the front of the back plate.

[0008] With the above-mentioned further configuration, the aging and wear of the conduit can be checked through the observation hole without flipping the back plate, reducing maintenance costs. The recessed structure serves as a side opening, increasing the gap between the conduit and the free end of the limiting plate, allowing the conduit to be squeezed or squeezed out from the side of the free end of the limiting plate. It can also serve as an operating window for the operator to insert their fingers to squeeze the conduit or assist in removing the conduit. At the same time, the conduit can be pushed to the side through the observation hole to assist in squeezing the limiting plate for removal and maintenance.

[0009] A further feature of this invention is that the corner of the wiring trough has an arc-shaped transition structure, and the contour of the trough cavity is adapted to the outer diameter of the bent conduit.

[0010] With the above-mentioned further design, the arc-shaped transition can eliminate stress concentration at bends and reduce the risk of conduit bending and breaking.

[0011] A further feature of this invention is that the free end edge of the limiting plate and the edge of the recessed structure are both provided with rounded chamfers.

[0012] With the above-mentioned further design, the rounded chamfer can prevent scratches on the surface of the conduit or on the operators.

[0013] Further features of this invention include at least one set of limiting plate units. Each limiting plate unit consists of two limiting plates arranged symmetrically and positioned at the opening of the wiring trough. The free ends of the two limiting plates of the limiting plate unit extend in opposite directions, and their fixed ends are integrally connected to the bottom of the wiring trough via a connecting straight plate.

[0014] With the above further configuration, the conduits can be split and arranged on both sides of the connecting plate, and two symmetrically arranged limiting plates can constrain and limit the conduits on both sides respectively.

[0015] A further feature of this invention is that a diversion block is provided at the corner of the wiring trough. The diversion block has a semi-cylindrical structure with its cylindrical axis parallel to the back plate surface. The diversion block includes a convex arc-shaped guide surface extending outward toward the corner of the wiring trough. The conduit is laid on the upper or lower side of the diversion block.

[0016] With the above-mentioned further configuration, a semi-cylindrical diverter block is set at the corner of the wiring trough to guide the parallel conduits into layers, allowing them to be distributed along different wiring trough routes. Its convex arc-shaped guide surface provides support for the upper conduits, and the arc-shaped structure reduces wear on the conduits.

[0017] A further feature of this invention is that a soft padding layer is added to the front of the back panel.

[0018] With the above-mentioned further design, the front of the back panel is padded to cover the exposed conduit at the observation hole, making the overall appearance more aesthetically pleasing. Attached Figure Description

[0028] like Figure 1-3 As shown, a wire harness fixing structure on a back plate includes a back plate 1 and several conduits 2 through which wire harnesses are threaded. A wiring groove 3 is provided on the back of the back plate 1, and the conduits 2 are accommodated in the wiring groove 3. The wiring groove 3 is arranged along the circumferential edge of the back plate 1. Limiting plates 4 are evenly distributed on the opening of the wiring groove 3. One end of the limiting plate 4 is a fixed end that is fixedly connected to the back plate 1, and the other end is a cantilevered free end. The fixed end of the limiting plate 4 is integrally connected to the side wall of the wiring groove 3, and the edge of the free end of the limiting plate 4 is rounded. The limiting plate 4 is elastic and preferably made of plastic. The conduits 2 are constrained between the limiting plate 4 and the bottom of the wiring groove 3.

[0029] The wall surface of the wiring groove 3 opposite the free end of the limiting plate 4 is provided with a recessed structure 7 to increase the gap between the recessed structure 7 and the free end of the limiting plate 4. The recessed structure 7 and the inner wall of the wiring groove 3 are rounded to make the whole smooth and prevent sharp parts from scratching the surface of the wire tube 2 or the operator. The recessed structure 7 serves as a side opening, increasing the gap between the recessed structure 7 and the free end of the limiting plate 4, allowing the wire tube 2 to be squeezed or squeezed out from the side of the free end of the limiting plate 4. It can also serve as an operating window for the operator to insert their fingers to squeeze the wire tube 2 or assist in removing the wire tube 2.

[0030] The bottom of the groove corresponding to the limiting plate 4 is provided with an observation hole 5 that connects to the front of the back plate 1. Through the observation hole 5, it is possible to check whether the conduit 2 is aging or worn without flipping the back plate 1, thus reducing maintenance costs. At the same time, the conduit 2 can be pushed to the side through the observation hole 5 to help the conduit 2 squeeze the limiting plate 4 to be removed for maintenance. In addition, a soft covering layer can be added to the front of the back plate 1 to cover the conduit 2 exposed at the observation hole 5, making the overall appearance more aesthetically pleasing.

[0031] In this embodiment, a limiting plate unit 6 is provided on the wiring trough 3 to divert multiple conduits 2, as shown in the attached figure. Figure 4 As shown, each limiting plate unit 6 is composed of two limiting plates 4 symmetrically arranged and set at the opening of the wiring groove 3. The free ends of the two limiting plates 4 of the limiting plate unit 6 extend back to back, and the fixed ends of both are integrally connected to the bottom of the wiring groove 3 through the connecting straight plate 9. The conduit 2 can be split and set through the connecting straight plate 9, and is respectively arranged on both sides of the connecting straight plate 9. The two symmetrically arranged limiting plates 4 respectively constrain and limit the conduit 2 on both sides.

[0032] Similarly, the recessed structure 7 facing outward on the wall of the wiring groove 3 opposite the free end of each limiting plate 4 of the limiting plate unit 6, and the observation hole 5 connected to the front of the back plate 1 are provided on the bottom of the groove corresponding to each limiting plate 4 of the limiting plate unit 6.

[0033] A diversion block 8 can also be set at the corner of the wiring trough 3. The diversion block 8 is preferably a semi-cylindrical structure with its cylindrical axis parallel to the back plate 1. The diversion block 8 includes a convex arc-shaped guide surface 81 extending outward toward the corner of the wiring trough 3. The conduit 2 is arranged on the upper or lower side of the diversion block 8.

[0034] By setting a semi-cylindrical diverter block 8 at the corner of the wiring trough 3, the parallel conduits 2 are further guided to be layered, which can distribute them along different wiring trough 3 routes, and its convex arc-shaped guide surface 81 provides support for the upper conduit 2. The arc structure reduces wear on the conduit 2.

[0035] Furthermore, the corner of the wiring trough 3 is an arc-shaped transition structure, and its cavity contour is adapted to the outer diameter of the bending of the conduit 2. The arc-shaped transition can eliminate stress concentration at the bend and reduce the risk of the conduit 2 bending and breaking. Any bend of the cable on the wiring trough 3 is an arc-shaped transition structure.

[0036] Specifically, in this embodiment, the back plate 1 can be placed at the edge of the wall, and the upper and lower ends of the back plate 1 can be connected to the ceiling or the ground. There is no need to connect to the fragile wall or dig a groove in the wall. The cantilevered limiting plate 4 cooperates with the wiring groove 3, and the conduit 2 can be directly pressed into the wiring groove 3. At the same time, the elastic deformation of the limiting plate 4 is used to achieve a snap-fit ​​fixation. No additional tools or bolts are needed. The conduit 2 is constrained between the limiting plate 4 and the bottom of the wiring groove 3, forming a two-way limiting fixation of the conduit 2, which can resist vibration or external pulling force. Moreover, this structure only requires the limiting plate 4 to have a certain degree of elasticity, which is suitable for various types of conduits 2, including PVC or metal conduits. Compared with the method of fixing the conduit 2 by pipe buckles, screws, anchors or adhesives, this embodiment has strong applicability and reliable installation.
