Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts, and more particularly to automotive wiring harnesses. Background Technology
[0002] Automotive wiring harnesses are the main network of automotive circuits. Without wiring harnesses, there would be no automotive circuits. A wiring harness is a group of metal wires and cables bundled together. It is the connection of signals and power between the equipment in the vehicle. It is the wiring component that connects various electrical devices in the automotive circuit. It combines the wires of different specifications and colors used by various electrical devices in the whole vehicle into a whole through reasonable arrangement and bundles the wires together with insulating material. This makes it both complete and reliable.
[0003] However, in actual use, wiring harnesses face many challenges. For example, the constant vibrations generated during vehicle operation can easily cause the wires in the harness to shake or shift, potentially leading to friction, wear, or even short circuits between the wires, which seriously affects the stability and safety of the vehicle's electrical system. At the same time, the ease of installation and removal of wiring harnesses also has a significant impact on work efficiency during the production, repair, and maintenance of automobiles.
[0004] Traditional automotive wiring harnesses may have design shortcomings. To ensure safety, they typically securely connect the wires to protective sleeves, making installation and removal cumbersome and time-consuming. This is especially true when replacing damaged wires, as the complex structure increases repair difficulty and time, hindering automotive maintenance. Furthermore, the complex installation and removal process can cause unnecessary damage to the wiring harness itself, further affecting its performance and lifespan. Utility Model Content
[0005] The purpose of this utility model is to provide an automotive wiring harness that improves upon the traditional automotive wiring harness, which fixes the harness to the protective sleeve, resulting in cumbersome installation and disassembly processes, increasing maintenance difficulty and time.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automotive wiring harness, comprising an upper protective sleeve and a lower protective sleeve, wherein a male connector is provided inside the upper and lower protective sleeves, and a wire is provided inside the male connector, one end of the wire being fixedly connected to a female connector; a guide rod is fixedly connected to the upper surface of the lower protective sleeve; a connecting plate is fixedly connected inside both the upper and lower protective sleeves; a clamping assembly is fixedly connected inside the connecting plate, the clamping assembly being used to fix the wire; a snap-fit assembly is provided inside the upper protective sleeve, the snap-fit assembly being used to fix the guide rod; the clamping assembly includes a second spring, one end of the second spring being fixedly connected inside the connecting plate, and the other end of the second spring being fixedly connected to an arc-shaped clamping plate, the arc-shaped clamping plate being fixedly connected to a limit ring.
[0007] Optionally, the snap-fit assembly includes a spring, one end of which is fixedly connected to the inside of the upper protective sleeve, and the other end of which is fixedly connected to a card.
[0008] Optionally, the outer wall of the conductor is provided with a tightening box, and the tightening box has a groove inside.
[0009] Optionally, a spring three is fixedly connected inside the tightening box, and a push plate is fixedly connected to one end of the spring three.
[0010] Optionally, a slide bar is fixedly connected to the upper surface of the push plate, and a slide groove is provided inside the tightening box.
[0011] Optionally, the outer wall of the slide bar is slidably connected to the inner wall of the slide groove.
[0012] Optionally, the guide rod has a slot inside, which is used to engage with a card.
[0013] Optionally, a pull rod is fixedly connected to the upper surface of the card.
[0014] The automotive wiring harness provided in this embodiment of the present invention has at least one of the following technical effects:
[0015] 1. In this utility model, the arc-shaped clamping plate compresses the wire under the elastic action of the second spring, and the limiting ring further clamps and fixes the wire, effectively preventing the wire from shaking or shifting inside the protective sleeve. The guide rod compresses and moves the card during the closing process, compressing the first spring. The elastic action of the first spring causes the card to be inserted into the slot inside the guide rod, thus enabling convenient installation and removal of the protective sleeve. This makes the maintenance and replacement of the wire harness much easier, greatly reducing the difficulty and time of wire harness maintenance.
[0016] 2. In this utility model, by inserting the wire harness into the tightening box, the wire harness will squeeze the push plate. Then, through the setting of the slide bar, the push plate can slide stably along the inside of the slide groove. During the movement of the push plate, the spring three will be squeezed and contracted. Then, through the reverse elastic action of the spring three, the push plate further tightens the wire, avoiding the situation where the wire is too long and causes mess or affects other components.

[0029] Reference Figure 1 - Figure 4This utility model provides an embodiment of an automotive wiring harness, including an upper protective sleeve 1 and a lower protective sleeve 2. Male connectors 4 are installed inside the upper and lower protective sleeves 1 and 2, and wires 3 are installed inside the male connectors 4. When a damaged wire 3 needs to be replaced, the protective sleeves must first be removed. Pulling the lever 10 to the left causes the lever 10 to disengage the clip 9 from the slot 11 inside the guide rod 8. Simultaneously, the spring 7 is compressed until the clip 9 is completely disengaged from the slot 11, thus releasing the lock on the guide rod 8. At this point, the upper protective sleeve 1 can be pulled upwards along the guide rod 8. After the upper and lower protective sleeves 1 and 2 are separated, the wire 3 that needs to be replaced can be located... The replacement wire 3 is removed, and then the new wire 3 is placed in the arc-shaped clamp 13 of the lower protective sleeve 2. One end of the wire 3 is fixedly connected to a female head 5. A guide rod 8 is fixedly connected to the upper surface of the lower protective sleeve 2. A connecting plate 12 is fixedly connected inside both the upper protective sleeve 1 and the lower protective sleeve 2. A clamping assembly is fixedly connected inside the connecting plate 12. The clamping assembly is used to fix the wire 3. A snap-fit assembly is provided inside the upper protective sleeve 1. The snap-fit assembly is used to fix the guide rod 8. The clamping assembly includes a second spring 15. One end of the second spring 15 is fixedly connected inside the connecting plate 12. The other end of the second spring 15 is fixedly connected to the arc-shaped clamp 13. A limit ring 14 is fixedly connected inside the arc-shaped clamp 13.
[0030] The snap-fit assembly includes a spring 7, one end of which is fixedly connected to the inside of the upper protective sleeve 1, and the other end of which is fixedly connected to a card 9. After placement, the upper protective sleeve 1 and the lower protective sleeve 2 can be merged. As the protective sleeves are merged, the arc-shaped clamp 13 inside will squeeze the wire 3 under the elastic action of the spring 15. Furthermore, the limiting ring 14 inside the arc-shaped clamp 13 can further clamp and fix the wire 3, effectively preventing the wire 3 from shaking or shifting inside the protective sleeve. At the same time, during the merging process of the protective sleeves, the upper protective sleeve 1 will be aligned and inserted along the guide rod 8 on the lower protective sleeve 2. During the insertion process, the guide rod 8 will push the card 9 to the left. At this time, the spring 7 is compressed. When the guide rod 8 is inserted to a certain depth, the card 9 will be snapped into the slot 11 inside the guide rod 8 under the elastic force of the spring 7, thereby realizing the connection and fixation of the upper protective sleeve 1 and the lower protective sleeve 2, thus ensuring the stability of the entire wire harness structure.
[0031] Reference Figure 1 and Figure 5A tightening box 6 is provided on the outer wall of the wire 3. A groove 20 is opened inside the tightening box 6. A spring 18 is fixedly connected inside the tightening box 6. A push plate 16 is fixedly connected to one end of the spring 18. When the tightening box 6 is needed to process the wire 3, the wire harness is passed through the tightening box 6 before use. At this time, the wire harness will squeeze the push plate 16 inside the tightening box 6, causing it to move into the groove 20. Then, through the setting of the sliding groove 17, the push plate 16 can slide stably along the sliding groove 17 through the sliding strip 19. The sliding strip 19 is fixedly connected to the upper surface of the push plate 16. The sliding groove 17 is opened inside the tightening box 6. The outer wall of the sliding strip 19 is slidably connected to the inner wall of the sliding groove 17. During the movement of the push plate 16, the spring 18 will also be squeezed and contracted. At this time, through the reverse elastic action of the spring 18, the push plate 16 can be driven to further tighten the wire 3, avoiding the wire 3 being too long and causing mess or affecting other components.
[0032] Working principle: When the damaged wire 3 in the wire harness needs to be replaced, the protective cover needs to be removed first. Pull the lever 10 to the left so that the lever 10 can drive the card 9 to disengage from the slot 11 inside the guide rod 8. At the same time, the spring 7 will also be squeezed and contracted until the card 9 is completely disengaged from the slot 11, thereby releasing the lock on the guide rod 8. At this time, the upper protective cover 1 can be pulled up along the guide rod 8.
[0033] After the upper protective sleeve 1 and the lower protective sleeve 2 are separated, the wire 3 that needs to be replaced is located and taken out. Then, the new wire 3 is placed in the arc-shaped clamp 13 of the lower protective sleeve 2. After placement, the upper protective sleeve 1 and the lower protective sleeve 2 can be merged. As the protective sleeves are merged, the arc-shaped clamp 13 inside will squeeze the wire 3 under the elastic action of the second spring 15. And through the setting of the limiting ring 14 inside the arc-shaped clamp 13, the wire 3 can be further clamped and fixed, effectively preventing the wire 3 from shaking or shifting inside the protective sleeve. At the same time, during the merging process of the protective sleeves, the upper protective sleeve 1 will be aligned and inserted along the guide rod 8 on the lower protective sleeve 2. During the insertion process, the guide rod 8 will push the card 9 to move to the left. At this time, the first spring 7 is compressed. When the guide rod 8 is inserted to a certain depth, the card 9 will be inserted into the card slot 11 inside the guide rod 8 under the elastic action of the first spring 7, thereby realizing the connection and fixation of the upper protective sleeve 1 and the lower protective sleeve 2, thus ensuring the stability of the entire wire harness structure.
[0034] When the tightening box 6 is needed to process the wire 3, the wire harness is passed through the tightening box 6 before use. At this time, the wire harness will squeeze the push plate 16 inside the tightening box 6, causing it to move into the groove 20. Then, through the setting of the slide groove 17, the push plate 16 can slide stably along the slide groove 17 through the slide bar 19. During the movement of the push plate 16, the spring 3 18 will also be squeezed and contracted. At this time, through the reverse elastic action of the spring 3 18, the push plate 16 can be driven to further tighten the wire 3, avoiding the situation where the wire 3 is too long and causes mess or affects other components.
[0035] The above description is only a preferred embodiment of the present utility model and is 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.
