Description

Technical Field

[0001] This utility model belongs to the field of automotive wiring harness fixing technology, and specifically relates to an automotive wiring harness that is easy to fix. Background Technology

[0002] Automotive wiring harnesses are a core component of automotive circuits, often referred to as the "neural network" of a car. They are responsible for the power supply and signal transmission of the entire vehicle's electrical equipment. They mainly consist of wires, connectors, protective components, and fixing accessories. The wires are the conductive core, with different specifications of copper core wire selected according to their application. Connectors enable detachable connections between the wiring harness and electrical equipment and must meet requirements for waterproofing, dustproofing, and vibration resistance. Protective components include corrugated tubing, braided sleeves, and tape, used to resist environmental influences such as high temperatures, oil stains, and abrasion. Fixing accessories, such as cable ties, brackets, and clips, ensure that the wiring harness is neatly arranged and reliably fixed within the vehicle body. Wiring harnesses require customized design based on the vehicle's electrical system layout, running through areas such as the engine compartment, passenger compartment, and chassis, connecting all electrical components such as the engine, instruments, lights, and sensors. They directly affect the normal operation of the car's power, safety, and comfort functions, and are a key carrier for ensuring the stable operation of the automotive electrical system.

[0003] Traditional automotive wiring harnesses are usually fixed with tape. However, the adhesiveness of the tape gradually decreases with the car's operating environment (high temperature, oil stains, vibration). If the wiring harness is fixed with tape alone for a long time, it is easy for it to loosen and shift. Therefore, a better way to fix the wiring harness is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient way to fix automotive wiring harnesses, which has the advantage of improving the fixation effect of automotive wiring harnesses.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a conveniently fixed automotive wiring harness, including a mounting shell, rectangular holes on both sides of the mounting shell, a wedge block slidably connected inside the rectangular holes, a stop block welded to one end of the wedge block, a fixing plate welded to one side of the wedge block, a limit rod slidably connected inside the fixing plate, a return spring sleeved on the surface of the limit rod, and the two ends of the return spring being connected between the mounting shell and the fixing plate respectively through spring fixing parts, an anti-slip plate welded to one side of the wedge block, and a limit plate welded to one side of the wedge block.

[0006] The above technical solution involves the following steps: During the movement of the moving plate, the push plate pushes and presses the inclined surface of the inclined block. Since the inclined surface of the inclined block is made of tempered glass, its surface is relatively smooth. When the inclined block is pressed by the push plate, it moves into the rectangular hole. The stop block is used to prevent the push plate from moving out of the inclined surface of the inclined block. When the inclined block moves, it drives the fixing plate to slide on the surface of the limiting rod, thus limiting the movement of the inclined block and preventing it from moving freely. The fixing plate also compresses the return spring. When two sets of inclined blocks inside a mounting housing move in opposite directions at the same time, they drive two sets of anti-slip plates to clamp the surface of the automotive wiring harness, thereby fixing the vehicle speed limit. Since the inclined blocks are adjustable, they can clamp and fix various specifications of automotive wiring harnesses. The anti-slip plate design prevents slippage while fixing the automotive wiring harness.

[0007] The present invention is further configured such that a connecting plate is welded to one side of the mounting shell, and sliding shells are welded to both sides of the mounting shell.

[0008] The above technical solution is adopted: the sliding shell is used to limit the movement of the plate.

[0009] The present invention is further configured such that a movable plate is slidably connected inside both sets of sliding shells, and a second screw is threaded inside one set of sliding shells, and the second screw is used to press the movable plate against the sliding shell.

[0010] The above technical solution is adopted: the second screw is turned so that it moves inside the sliding shell and abuts against the surface of the moving plate, thereby fixing the position of the moving plate.

[0011] The present invention is further configured such that push plates are welded to both sides of the movable plate, and the push plates are slidably connected to the inclined block.

[0012] The above technical solution utilizes a reset spring, which allows the inclined block to be pushed outward and reset when it is not being squeezed by the push plate.

[0013] The present invention is further configured such that a fixing ring is welded to one side of the connecting plate, and a first half-corrugated pipe is welded between the two sets of fixing rings.

[0014] The above technical solution is adopted: the fixing ring is used for the installation and fixing of the first half of the corrugated pipe.

[0015] The present invention is further configured such that a rotating ring is rotatably connected to the surface of the fixed ring, and a second half-corrugated pipe is welded between the two sets of rotating rings. A first screw is threadedly connected inside one set of rotating rings, and the first screw is used to abut against the surface of the fixed ring.

[0016] Using the above technical solution: When fixing the automotive wiring harness, the wiring harness is covered by the first and second half-corrugated tubes, thus protecting it. After prolonged use, dust, insects, etc., may enter the space formed by the first and second half-corrugated tubes from the mounting housing. At this time, the first screw can be loosened to disengage it from the retaining ring. Then, the rotating ring on the surface of the retaining ring will rotate the second half-corrugated tube to the other side of the first half-corrugated tube (from...). Figure 1 It can be seen that the overall size of the second half-corrugated pipe is slightly larger than that of the first half-corrugated pipe. This allows the dust in the space formed by the first and second half-corrugated pipes to be removed without disassembling the fixing structure.

[0017] In summary, this utility model has the following beneficial effects: 1. The design of the inclined blocks allows for the positioning of automotive wiring harnesses of various specifications. 2. The design of the second half-corrugated pipe, the first half-corrugated pipe, the fixing ring, and the swivel ring facilitates the cleaning of dust in the space formed by the second half-corrugated pipe and the first half-corrugated pipe.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example 1: refer to Figures 1-3A conveniently fixed automotive wiring harness includes a mounting housing 7. Rectangular holes 8 are provided on both sides of the mounting housing 7. An inclined block 13 is slidably connected inside the rectangular holes 8. A stop block 14 is welded to one end of the inclined block 13. A fixing plate 17 is welded to one side of the inclined block 13. A limit rod 15 is slidably connected inside the fixing plate 17. A return spring 16 is sleeved on the surface of the limit rod 15. The two ends of the return spring 16 are respectively connected between the mounting housing 7 and the fixing plate 17 through spring fixing parts. An anti-slip plate 18 is welded to one side of the inclined block 13. A limit plate 19 is welded to one side of the inclined block 13. The design of the inclined block 13 and the anti-slip plate 18 can clamp and fix automotive wiring harnesses of various specifications. refer to Figure 1 , Figure 2 , Figure 4 A connecting plate 6 is welded to one side of the mounting shell 7, and sliding shells 9 are welded to both sides of the mounting shell 7. The sliding shells 9 are used to limit the movement of the moving plate 11. refer to Figure 1 and Figure 2 The two sets of sliding shells 9 are slidably connected to a movable plate 11 inside. One set of sliding shells 9 is threaded with a second screw 10 inside, and the second screw 10 is used to press the movable plate 11 against the sliding plate 11 and to fix the movable plate 11 inside the sliding shell 9. refer to Figures 1-3 Push plates 12 are welded on both sides of the movable plate 11, and the push plates 12 are slidably connected to the inclined block 13. The push plates 12 are used to push the inclined block 13 into the mounting housing 7 and fix the automotive wiring harness.

[0022] Brief description of usage: During use, both ends of the automotive wiring harness are inserted into the two sets of mounting housings 7 respectively. At this time, one end of the automotive wiring harness is located between the corresponding two sets of inclined blocks 13. Then, the second screw 10 is turned to move the second screw 10 outward and release it from the clamping of the moving plate 11. Next, the moving plate 11 is pushed to move. During the movement of the moving plate 11, it will drive the push plate 12 to push and squeeze the inclined surface of the inclined block 13. Since the inclined surface of the inclined block 13 is made of tempered glass, the surface is relatively smooth. When the inclined block 13 is squeezed by the push plate 12, it will move into the rectangular hole 8. The stop block 14 is used to prevent the push plate 12 from moving out of the inclined surface of the inclined block 13. When the inclined block 13 moves, it will drive the fixing plate 17 to slide on the surface of the limiting rod 15, so that the limiting rod 15 is pressed against the inclined block 13. The movement of 3 is limited to prevent the inclined block 13 from moving freely, and the fixing plate 17 will compress the return spring 16. When the two sets of inclined blocks 13 inside a mounting housing 7 move towards each other at the same time, they will drive the two sets of anti-slip plates 18 to clamp the surface of the car wiring harness at the same time, thereby fixing the car speed limit. Since the inclined block 13 is adjustable, it can clamp and fix car wiring harnesses of various specifications. The design of the anti-slip plate 18 can prevent slippage while fixing the car wiring harness. Finally, the second screw 10 is turned again, so that the second screw 10 moves inside the sliding housing 9 and abuts against the surface of the moving plate 11, thereby fixing the position of the moving plate 11. However, the use of the return spring 16 can push the inclined block 13 to move outward and reset when the inclined block 13 is not squeezed by the push plate 12.

[0023] Example 2: refer to Figure 1 , Figure 2 , Figure 4 A fixing ring 1 is welded to one side of the connecting plate 6, and a first half-corrugated pipe 2 is welded between the two sets of fixing rings 1. The fixing ring 1 is used to fix the first half-corrugated pipe 2. refer to Figure 1 , Figure 4 A rotating ring 4 is rotatably connected to the surface of the fixed ring 1. A second half-corrugated pipe 3 is welded between the two sets of rotating rings 4. A first screw 5 is threaded inside one set of rotating rings 4 and is used to press against the surface of the fixed ring 1. The first screw 5 is used to fix the position of the second half-corrugated pipe 3.

[0024] Brief description of usage: When fixing the automotive wiring harness, the harness is covered by the first half-corrugated tube 2 and the second half-corrugated tube 3, thus protecting it. After prolonged use, dust, insects, etc., may enter the space formed by the first half-corrugated tube 2 and the second half-corrugated tube 3 through the mounting shell 7. At this time, the first screw 5 can be loosened to release it from the fixing ring 1. Then, the rotating ring 4 on the surface of the fixing ring 1 is rotated. The rotating ring 4 will drive the second half-corrugated tube 3 to rotate to the other side of the first half-corrugated tube 2 (from...). Figure 1 It can be seen that the overall size of the second half-corrugated pipe 3 is slightly larger than that of the first half-corrugated pipe 2. In this way, the dust in the space formed by the first half-corrugated pipe 2 and the second half-corrugated pipe 3 can be removed without disassembling the fixing structure.

[0025] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
