Description

Technical Field

[0001] This utility model relates to the field of automotive internal electrical connection wiring harness technology, and in particular to a flat wiring harness for automotive internal electrical connection. Background Technology

[0002] With the rapid development of the automotive industry, the number of electrical devices inside automobiles is increasing and their functions are becoming more complex. Flat wire harnesses used for electrical connections in automobiles are key components for realizing power transmission and signal interaction among various electrical components, and their performance directly affects the stability and reliability of the automotive electrical system.

[0003] In existing technologies, automotive flat wiring harnesses are prone to loosening, displacement, or even detachment during vehicle operation due to vehicle vibration and relative movement of components. This is especially true in scenarios involving components that require frequent adjustments, such as power seats and doors. When a wiring harness detaches, it can cause electrical equipment to malfunction and, in severe cases, pose a safety hazard. Furthermore, existing wiring harness fixing methods often employ simple cable ties or clips. These fixing structures lack effective control over wiring harness displacement under different operating conditions and cannot meet the requirements for preventing detachment of wiring harnesses in dynamic environments.

[0004] To address this, a flat wiring harness for connecting electrical components in automobiles is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a flat wiring harness for electrical connections in automobiles, which can solve the problem that existing flat wiring harnesses in automobiles are prone to loosening, displacement, or even falling off during vehicle operation due to vehicle vibration and relative movement of components.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flat wiring harness for connecting electrical components in an automobile, comprising a wiring harness body, both ends of which are fixedly connected to end caps, and an anti-detachment mechanism provided in the middle of the wiring harness body, the anti-detachment mechanism comprising a fixing component and a supporting component, the fixing component comprising a U-shaped placement bracket;

[0007] The support assembly includes a connecting block, which is fixedly connected to the end near the side of the U-shaped placement frame. Fixing blocks are fixedly connected to both the front and rear sides of the U-shaped placement frame. A support rod is rotatably connected to the surface of the fixing block, and the other end of the support rod is rotatably connected to the outside of the connecting block.

[0008] Preferably, the top of the U-shaped placement rack has grooves on the front and rear sides, and a metal cover plate is rotatably connected inside the front groove.

[0009] Preferably, a rubber pad is fixedly connected to the bottom of the metal cover plate, and the side of the rubber pad closest to the wire harness body is in close contact with the wire harness body.

[0010] Preferably, a magnetic block is fixedly connected to the bottom of the inner wall of the rear groove, and the magnetic block is used in conjunction with the metal cover plate.

[0011] Preferably, a positioning rod runs through the inside of the support rod, and a positioning groove is provided on the side of the fixing block near the positioning rod, and the positioning groove is distributed in a ring. The positioning groove is used in conjunction with the positioning rod.

[0012] Preferably, a pull ring is fixedly connected to the outside of the positioning rod, and a tension spring is sleeved on the surface of the positioning rod, with both ends of the tension spring being fixedly connected to the pull ring and the support rod, respectively.

[0013] Preferably, a protective layer is fixedly sleeved on the surface of the main body of the wire harness, and the protective layer is made of low-density polyethylene.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application sets up a support component, which, through the cooperation of connecting blocks, support rods, and fixing blocks, and the engagement of positioning rods and positioning slots, can form a mechanical locking structure. When the main body of the wire harness is subjected to abnormal tension, the positioning rods are embedded in the positioning slots, restricting the rotation of the support rods, thereby preventing the main body of the wire harness from falling off due to excessive pulling. Compared with traditional fixing methods, the reliability of anti-detachment is significantly improved.

[0016] 2. By setting a fixing component, this application can enclose the main body of the wire harness within the placement frame. This not only limits the position of the main body of the wire harness but also prevents external impurities such as dust and moisture from entering, providing good protection for the main body of the wire harness, avoiding damage to the main body of the wire harness due to external corrosion, and extending its service life.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 The present invention provides the following technical solution:

[0026] A flat wiring harness for connecting electrical components in an automotive vehicle includes a wiring harness body 1, with end caps 2 fixedly connected to both ends of the wiring harness body 1. An anti-detachment mechanism 3 is provided in the middle of the wiring harness body 1. The anti-detachment mechanism 3 includes a fixing component 31 and a support component 32. The fixing component 31 includes a U-shaped placement bracket 311.

[0027] The support assembly 32 includes a connecting block 321, which is fixedly connected to the end 2 on the side near the U-shaped placement frame 311. Fixing blocks 322 are fixedly connected to the front and rear sides of the U-shaped placement frame 311. A support rod 323 is rotatably connected to the surface of the fixing block 322, and the other end of the support rod 323 is rotatably connected to the outside of the connecting block 321.

[0028] In this embodiment: by setting a support component 32, the connecting block 321 is the connection node between the support component 32 and the wire harness end 2, which can transmit the tension of the support rod 323 to the wire harness body 1. The fixing block 322 is the rotation fulcrum of the support rod 323, which can be rigidly connected to the U-shaped placement frame 311 to transmit the support force to the middle fixing structure of the wire harness body 1. The support rod 323 can connect the connecting block 321 and the fixing block 322 to form a rotatable linkage mechanism. Under normal conditions, the wire harness body 1 is allowed to swing slightly with the end 2. When subjected to abnormal tension, the positioning rod 4 and the positioning groove 5 lock the angle, which can prevent the wire harness body 1 from moving further, thereby achieving the anti-detachment effect.

[0029] Specifically, such as Figure 3 As shown, the top of the U-shaped placement rack 311 has grooves 312 on the front and rear sides, and a metal cover plate 313 is rotatably connected inside the front groove 312.

[0030] Specifically, such as Figure 3 As shown, a rubber pad 314 is fixedly connected to the bottom of the metal cover plate 313, and the side of the rubber pad 314 near the wire harness body 1 is in close contact with the wire harness body 1.

[0031] Specifically, such as Figure 3 As shown, a magnetic block 315 is fixedly connected to the bottom of the inner wall of the rear groove 312, and the magnetic block 315 is used in conjunction with the metal cover plate 313.

[0032] In this embodiment: Through the above settings, the groove 312 can provide installation positions for components such as the metal cover plate 313 and the magnetic block 315, ensuring that the layout of each component on the U-shaped placement frame 311 is accurate. After the metal cover plate 313 is closed, it can form a complete wrapping structure with the U-shaped placement frame 311, restricting the wire harness body 1 in the internal space and preventing the wire harness body 1 from loosening or falling out. In addition, the rotating connection design of the metal cover plate 313 facilitates installation and maintenance. During installation, the cover plate is opened and the wire harness body 1 is placed in. During maintenance, the wire harness body 1 can be quickly disassembled for inspection or replacement. The elasticity of the rubber pad 314 allows it to fit tightly with the wire harness body 1, and the friction further fixes the wire harness body 1, preventing it from shaking up and down. At the same time, the soft rubber material can reduce the direct rigid contact between the metal cover plate 313 and the wire harness body 1, avoiding the edge of the cover plate from scratching the outer skin of the wire harness body 1. The magnetic block 315 can be magnetically attracted to the metal cover plate 313 to achieve automatic locking after the cover plate is closed, without the need for additional screws or buckles, simplifying the operation process.

[0033] Specifically, such as Figure 6 As shown, a positioning rod 4 runs through the inside of the support rod 323, and a positioning groove 5 is provided on the side of the fixing block 322 near the positioning rod 4. The positioning groove 5 is distributed in a ring and is used in conjunction with the positioning rod 4.

[0034] Specifically, such as Figure 6 As shown, a pull ring 6 is fixedly connected to the outside of the positioning rod 4, and a tension spring 7 is sleeved on the surface of the positioning rod 4, with both ends of the tension spring 7 being fixedly connected to the pull ring 6 and the support rod 323 respectively.

[0035] In this embodiment: Through the above settings, the positioning rod 4, by inserting into the positioning groove 5 on the fixing block 322, can restrict the rotational freedom of the support rod 323, fixing the wire harness body 1 at a preset angle. When the wire harness body 1 and the end 2 are subjected to vibration or external force pulling, the positioning rod 4 can withstand shear force, preventing the support rod 323 from loosening and ensuring the stability of the end 2 connection. The annularly distributed grooves allow the support rod 323 to achieve multi-angle locking within a 360-degree range, which can adapt to the wiring needs of different vehicle models or installation positions. The pull ring 6 allows the user to manually pull the positioning rod 4 out of the positioning groove 5 to achieve angle adjustment, improving ease of use. The elastic force of the tension spring 7 can keep the positioning rod 4 always inserted into the positioning groove 5, ensuring the reliability of the locking state.

[0036] Specifically, such as Figure 5 As shown, a protective layer 8 is fixedly sleeved on the surface of the main body 1 of the wire harness. The protective layer 8 is made of low-density polyethylene.

[0037] In this embodiment: Through the above settings, low-density polyethylene has the characteristics of being soft and elastic, which can buffer the wear of the wire harness body 1 caused by vibration, compression or friction inside the car, avoid damage or breakage of the internal wire insulation layer, and extend the service life of the wire harness body 1.

[0038] Working principle: First, rotate the metal cover plate 313 so that the magnetic block 315 tightly adheres to the metal cover plate 313, preventing the metal cover plate 313 from opening due to vibration. The rubber pad 314 will fit tightly against the surface of the protective layer 8, thereby fixing and limiting the main body 1 of the wire harness, preventing it from sliding in the U-shaped placement bracket 311. Then, align the ends 2 of the main body 1 of the wire harness with the interface of the automotive electrical equipment to ensure the accuracy of the electrical connection. Next, according to the direction of the main body 1 of the wire harness in the vehicle and the installation space, pull the pull ring 6 outward to separate the positioning rod 4 from the positioning groove 5. Then, manually rotate the support rod 323 to adjust the tilt angle or position of the U-shaped placement bracket 311 so that the main body 1 of the wire harness can adapt to different installation paths. After adjusting to the appropriate angle, release the pull ring 6. The restoring force of the tension spring 7 will push the positioning rod 4 into the corresponding positioning groove 5, thereby locking the angle of the support rod 323 and achieving the anti-detachment effect.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
