Description

Technical Field

[0001] This utility model relates to the field of high-voltage wiring harnesses, specifically a protective high-voltage wiring harness for vans. Background Technology

[0002] New energy minivans, powered by electricity, require a large number of high-voltage wiring harnesses. The thin insulation of these harnesses alone is insufficient to achieve adequate insulation between adjacent wires. Therefore, during manufacturing, the insulation layer is intentionally thickened to enhance insulation performance. However, this not only consumes more raw materials for the insulation layer but also significantly increases the overall weight of the harness, making subsequent installation difficult and resulting in a less than ideal overall performance.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a protective high-voltage wiring harness for vans, which can improve the protection effect of the wiring harness.

[0005] To solve the above problems, the technical solution of this utility model is as follows: a protective high-voltage wiring harness for vans, comprising a wiring harness body, wherein a protective collar one and a protective collar two are sleeved on the surface of the wiring harness body, both the protective collar one and the protective collar two are semi-circular, the protective collar one is provided with a connecting plate one at both ends, the protective collar two is provided with a connecting plate two at both ends, a connecting rod is provided at the ends of the connecting plate one and the connecting plate two that are far apart from each other, a slot is provided at the other ends of the connecting plate one and the connecting plate two that are far apart from each other, and a ball is provided at the other end of the connecting rod;

[0006] Dovetail blocks are fixedly connected to the lower end of the connecting plate. There are multiple sets of dovetail blocks, and a limiting block is slidably provided at one end of each dovetail block.

[0007] Dovetail groove, the dovetail groove is formed at the upper end of the connecting plate two, and the dovetail groove is correspondingly set with the dovetail block;

[0008] A square groove is formed at the upper end of the connecting plate 2. The square groove is located on one side of the dovetail groove and is connected to the dovetail groove.

[0009] A limiting structure is located inside the slot.

[0010] Furthermore, the limiting structure includes a vertical plate, a rotating shaft inside the vertical plate, an arc-shaped plate sleeved on the surface of the rotating shaft, two sets of arc-shaped plates, each set of arc-shaped plates being independently rotatably connected to the rotating shaft, a short plate at the outer end of the arc-shaped plate, a spring at one end of the short plate, and the other end of the spring being fixedly connected to the vertical plate, with the sphere located between the two arc-shaped plates.

[0011] Furthermore, the dovetail block has a cavity inside, and a second spring is installed inside the cavity. A telescopic rod is installed inside the second spring. One end of the telescopic rod is fixedly connected to the inner wall of the cavity, and the other end is fixedly connected to the limiting block.

[0012] Furthermore, the dovetail block matches the dovetail groove, the dovetail block can be placed inside the square groove, and one end of the limiting block is an inclined surface.

[0013] Furthermore, the outer side of the arc of the first and second protective collars is provided with a wear-resistant layer.

[0014] The advantages of this invention compared to existing technologies are as follows:

[0015] (1) In this utility model, the connecting plate one and the connecting plate two are aligned, and then the dovetail block is placed into the square groove. At this time, the connecting plate two presses the limiting block, and the limiting block slides into the cavity, thereby compressing the spring two and the telescopic rod. After the dovetail block is completely inserted into the square groove, the spring two returns to its original state. The elastic force of the spring two causes the dovetail block to move into the dovetail groove, so that the dovetail block is limited by the dovetail groove and cannot be directly taken out from the dovetail groove. At the same time, without the action of external force, the setting of the spring two can make the dovetail block located inside the dovetail groove, and the setting of the telescopic rod can ensure the smooth movement of the limiting block. Thus, the above operation can conveniently and quickly fix the connecting protective collar one and the protective collar two, thereby protecting the high voltage wire harness.

[0016] (2) This utility model moves the connecting rod and the ball into the slot, so that the ball squeezes the two arc plates outward, thereby driving the short plate to move, so that the spring one deforms until the ball enters the two arc plates. The spring one returns to its original shape, and the arc plates fix the ball. Without the action of external force, the ball can be prevented from moving freely, thereby completing the splicing of protective collar one and protective collar two. Multiple sets of protective collar one and protective collar two can be spliced ​​together to extend the use and make it more flexible. Attached Figure Description

[0027] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figures 1 to 7As shown, a protective high-voltage wiring harness for a van includes a wiring harness body 1. A protective collar 2 and a protective collar 3 are fitted onto the surface of the wiring harness body 1. Both the protective collar 2 and the protective collar 3 are semi-circular. The protective collar 2 and the protective collar 3 combine to form a circular sleeve that fits over the surface of the high-voltage wiring harness body 1, thereby protecting the high-voltage wiring harness body 1 and ensuring its wear resistance and insulation, thus guaranteeing the normal operation of the high-voltage cable. A wear-resistant layer is installed on the outer arc of the protective collar 2 and the protective collar 3 to improve protective performance.

[0030] Connecting plates 8 are installed at both ends of the protective collar 2, and connecting plates 9 are installed at both ends of the protective collar 3. Dovetail blocks 4 are fixedly installed at the lower end of connecting plate 8. There are multiple sets of dovetail blocks 4. A limit block 5 is slidably installed at one end of the dovetail block 4. A dovetail groove 6 is opened at the upper end of the connecting plate 9. The dovetail groove 6 and the dovetail block 4 are set one-to-one. A square groove 7 is opened at the upper end of the connecting plate 9. The square groove 7 is located on one side of the dovetail groove 6 and is connected to the dovetail groove 6. The dovetail block 4 matches the dovetail groove 6 and can be placed inside the square groove 7.

[0031] A cavity is opened inside the dovetail block 4, and a spring 19 is installed inside the cavity. A telescopic rod 20 is installed inside the spring 19. One end of the telescopic rod 20 is fixedly connected to the inner wall of the cavity, and the other end is fixedly connected to the limiting block 5. One end of the limiting block 5 is an inclined surface.

[0032] When it is necessary to splice protective collar 12 and protective collar 23, align connecting plate 18 and connecting plate 29, and then insert dovetail block 4 into square groove 7. At this time, connecting plate 29 presses against limiting block 5, and limiting block 5 slides into the cavity, thereby compressing spring 219 and telescopic rod 20 until dovetail block 4 is completely inside square groove 7. Then spring 219 returns to its original state, and the elasticity of spring 219 causes dovetail block 4 to move into dovetail groove 6. Thus, dovetail block 4 is limited by dovetail groove 6 and cannot be directly removed from inside dovetail groove 6. At the same time, without external force, the setting of spring 219 can keep dovetail block 4 inside dovetail groove 6, and the setting of telescopic rod 20 can ensure the smooth movement of limiting block 5. Thus, the above operation can fix and connect protective collar 12 and protective collar 23.

[0033] Connecting rods 10 are installed at the ends of connecting plate 1 8 and connecting plate 2 9 that are far apart from each other. Slots 12 are opened at the other ends of connecting plate 1 8 and connecting plate 2 9 that are far apart from each other. A ball 11 is installed at the other end of the connecting rod 10. The limiting structure 13 is located inside the slot 12. When multiple sets of protective collars 1 2 and protective collars 2 3 need to be spliced ​​to achieve extension, it can be achieved through the limiting structure 13, connecting rods 10, and ball 11.

[0034] The limiting structure 13 includes a vertical plate 17, a rotating shaft 18 is installed inside the vertical plate 17, and an arc plate 14 is sleeved on the surface of the rotating shaft 18. There are two sets of arc plates 14, and the two sets of arc plates 14 are independently rotatably connected to the rotating shaft 18. A short plate 15 is installed at the outer end of the arc plate 14, and a spring 16 is installed at one end of the short plate 15. The other end of the spring 16 is fixedly connected to the vertical plate 17.

[0035] Specifically, during assembly, the connecting rod 10 and the ball 11 are moved into the slot 12, causing the ball 11 to press the two arc plates 14 outwards, thereby moving the short plate 15 and deforming the spring 16 until the ball 11 enters the two arc plates 14. The spring 16 then returns to its original shape, and the arc plates 14 fix the ball 11, preventing it from moving freely without external force. This completes the assembly of the protective collar 2 and the protective collar 3. When separation is required, the ball 11 presses the arc plates 14 at both ends, causing the two arc plates 14 to rotate around the pivot 18. At the same time, the two short plates 15 rotate outwards, causing the two springs 16 to deform. The springs 16 can bend due to their properties. When the ball 11 detaches from the arc plates 14, the springs 16 return to their original shape, thus enabling separation.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
