Description

Technical Field

[0001] This utility model relates to the field of wire harness clip technology, specifically a wire harness clip with a built-in protective structure. Background Technology

[0002] A wire harness clip is a device used to secure wire harnesses. It is widely used in various scenarios involving wire harnesses, especially in the automotive and electronic equipment industries. In automobiles, wire harnesses are like the neural network of the human body, connecting various electrical modules to achieve power distribution and signal transmission. Effective securing of the wire harness is crucial for the normal operation of automotive electronic and electrical functions.

[0003] Traditional wire harness clips with built-in protection structures often use a single clip or tape for fixation, lacking multi-dimensional positioning and buffer design. This makes the wire harness prone to displacement or wear in vibration environments, especially in high-frequency vibration scenarios such as automobiles. This can lead to safety hazards such as damage to the wire harness sheath and poor circuit contact. Traditional clips cannot be easily cascaded and expanded. When multiple sets of wire harnesses need to be fixed, multiple independent structures need to be installed separately, resulting in a cumbersome installation process, high cost, and inconvenient operation. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a wire harness clip with a built-in protective structure to solve the problems mentioned in the background.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wire harness clip with a built-in protective structure, comprising a clip and a wire harness protective sleeve one and a wire harness protective sleeve two adapted and installed with the clip. The clip has recessed portions on both sides, with the top of each recessed portion having an arc-shaped structure. The inner diameter surfaces of both the wire harness protective sleeve one and the wire harness protective sleeve two are fixedly provided with several rubber strips distributed in a "C" shape. The outer sides of both the wire harness protective sleeve one and the wire harness protective sleeve two are fixedly provided with lower hook rings, which are inserted into the recessed portions. The inner sides of both the wire harness protective sleeve one and the wire harness protective sleeve two together wrap around the wire harness that passes through the clip. The main body of the wire harness is in contact with the rubber strip. A first alignment rod is fixedly provided on the outer side of the first wire harness protective sleeve, and a second alignment rod is fixedly provided on the outer side of the second wire harness protective sleeve. A hook block is provided at the connection between the first and second alignment rods. The first and second alignment rods are hooked to each other by the hook block. The wire clip has a first adaptation groove that matches the first alignment rod on the side near the first wire harness protective sleeve, and a second adaptation groove that matches the second alignment rod on the side near the second wire harness protective sleeve. Both the first and second wire harness protective sleeves have an upper through hole on their inner diameter surfaces.

[0008] Through the above technical solution, the first wire harness protective sleeve and the second wire harness protective sleeve can fit tightly into the internal space of the wire clip, avoiding wire harness shaking or displacement caused by the width gap, and ensuring the stability and vibration resistance of the wire harness fixation.

[0009] Preferably, one end of the wire clip is fixedly provided with a snap-fit ​​strip, and the other end is provided with a snap-fit ​​groove adapted to the snap-fit ​​strip. A rotating shaft is provided at the opening at the top of the wire clip, and a pressure plate is rotatably installed through the rotating shaft. A hook plate is fixedly provided on the side of the pressure plate facing the wire clip. A hook groove is provided at the position corresponding to the hook plate on the wire clip. A lower through hole is provided at the bottom of the inner side of the wire clip, and a locking bolt is threaded into the lower through hole.

[0010] Through the above technical solution, multiple sets of wire clips can be quickly spliced ​​together through the clip strip and clip slot, meeting the needs of different wire harness layouts and improving installation efficiency.

[0011] Preferably, the rubber strip is made of elastic rubber with a semi-circular cross-section, and the spacing between adjacent rubber strips is 2mm to 5mm. When the wire harness body comes into contact with the rubber strip, the rubber strip is compressed by 0.5mm to 1.5mm to enhance friction and provide cushioning.

[0012] Through the above technical solution, the semi-circular rubber strip made of elastic rubber deforms under pressure and tightly wraps the wire harness body with a compression amount of 0.5mm to 1.5mm. This not only increases friction to prevent the wire harness from shifting, but also reduces vibration damage to the wire harness through elastic buffering.

[0013] Preferably, the hook block has a shark tooth structure with serrated edges or multiple sharp tooth protrusions; the hook block is provided at the ends of both the first alignment rod and the second alignment rod.

[0014] Through the above technical solution, the shark tooth structure hook block uses the meshing action of serrated sharp teeth to form a mechanical self-locking effect, ensuring the precise docking of the first alignment rod and the second alignment rod, and effectively preventing the wire harness protective sleeve from lateral displacement after installation.

[0015] Preferably, the depth of the concave portion is 80% to 90% of the height of the lower hook ring, and the lower hook ring has a "C" shaped structure, with its opening direction consistent with the arc direction of the concave portion.

[0016] Through the above technical solution, the interference fit between the lower hook ring and the concave part forms an elastic snap-fit, and the 80% to 90% depth matching ensures the stability of the insertion. The C-shaped opening direction and the matching design of the arc structure make it difficult for the wire harness protective sleeve 2 and wire harness protective sleeve 1 to fall off after being snapped into the wire clip, thus improving the reliability of the structure.

[0017] Preferably, the top of the pressure plate adopts a concave arc-shaped structure, the C-shaped opening of the upper through hole faces the inside of the wire clip, and the radii of the upper through hole and the lower through hole are consistent.

[0018] Through the above technical solution, the concave arc structure of the pressure plate can evenly press the wire harness body, and the rubber strip will be compressed by 0.5mm to 1.5mm, which can ensure the fixing force and avoid excessive compression of the wire harness. The design of keeping the radius of the upper through hole and the lower through hole consistent will not affect the installation.

[0019] Preferably, the overall width of the assembled wire harness protective sleeve one and wire harness protective sleeve two is equal to the width inside the wire clip.

[0020] The above technical solution makes it less likely for the second wire harness protective sleeve and the first wire harness protective sleeve to fall off after being secured inside the wire clip, thus improving structural reliability.

[0021] Compared with the prior art, this utility model provides a wire harness clip with a built-in protective structure, which has the following beneficial effects:

[0022] 1. The wire harness clip with built-in protective structure, wire harness protective sleeve one and wire harness protective sleeve two are connected by a hook block with a shark tooth structure and a precise insertion of the alignment rod and the adapter groove. With the interference fit between the inner concave part of the clip and the lower hook ring, the wire harness is fixed without deviation. With the elastic compression of the rubber strip, it can suppress axial movement through friction and buffer vibration energy to reduce wire harness wear.

[0023] 2. The wire harness clip with built-in protection structure can be quickly cascaded and assembled through the cooperation of the clip strip and the clip slot, which can meet the needs of fixing multiple wire harnesses in parallel without the need for additional tools or complicated operations. At the same time, disassembly only requires loosening the bolts and pressure plate, which facilitates later maintenance or wire harness replacement and reduces operation and maintenance costs.

[0036] 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.

[0037] Example 1:

[0038] like Figure 1 — Figure 11 As shown, this utility model provides a wire harness clip with a built-in protective structure, including a wire harness clip 1 and wire harness protective sleeves 1-9 and 2-10 that are adapted and installed with the wire harness clip 1. The wire harness clip 1 has recessed portions 2 on both sides, with the top of the recessed portion 2 having an arc-shaped structure. Several rubber strips 13 arranged in a "C" shape are fixedly provided on the inner diameter surfaces of both the wire harness protective sleeves 1-9 and 2-10. Lower hook rings 20 are fixedly provided on the outer sides of both the wire harness protective sleeves 1-9 and 2-10, and are inserted into the recessed portions 2. The inner sides of the wire harness protective sleeves 1-9 and 2-10 together wrap around the wire harness body 18 that penetrates the wire harness clip 1. The wire harness body 18 and the rubber strips 13 are connected to the recessed portion 2. The adhesive strip 13 engages in contact with the wire harness protective sleeve 9. A first alignment rod 11 is fixedly provided on the outer side of the wire harness protective sleeve 10, and a second alignment rod 12 is fixedly provided on the outer side of the wire harness protective sleeve 20. A hook block 21 is provided at the connection between the first alignment rod 11 and the second alignment rod 12. The first alignment rod 11 and the second alignment rod 12 are hooked together by the hook block 21. A first adaptation groove 14 that matches the first alignment rod 11 is opened on the side of the wire harness protective sleeve 10 near the wire harness protective sleeve 9, and a second adaptation groove 15 that matches the second alignment rod 12 is opened on the side of the wire harness protective sleeve 20. An upper through hole 19 is opened on the inner diameter surface of both the wire harness protective sleeve 10 and the wire harness protective sleeve 20.

[0039] The advantage is that the wire harness protective sleeve 19 and the wire harness protective sleeve 20 can fit tightly into the internal space of the wire clip 1, avoiding the wire harness shaking or shifting due to the width gap, and ensuring the stability and vibration resistance of the wire harness fixation.

[0040] Example 2:

[0041] like Figure 2 — Figure 11As shown, as an improvement on the previous embodiment, one end of the wire clip 1 is fixedly provided with a snap-fit ​​strip 17, and the other end is provided with a snap-fit ​​groove 16 adapted to the snap-fit ​​strip 17. A rotating shaft 3 is provided at the opening at the top of the wire clip 1, and a pressure plate 4 is rotatably installed through the rotating shaft 3. A hook plate 6 is fixedly provided on the side of the pressure plate 4 facing the wire clip 1. A hook groove 5 is provided at the corresponding position of the wire clip 1 and the hook plate 6. A lower through hole 7 is provided at the bottom of the inner side of the wire clip 1, and a locking bolt 8 is threadedly connected inside the lower through hole 7. The advantage is that multiple sets of wire clips 1 can be quickly spliced ​​through the snap-fit ​​strip 17 and the snap-fit ​​groove 16 to meet the needs of different wire harness layouts and improve installation efficiency.

[0042] Example 3:

[0043] like Figure 2 — Figure 11 As shown, as an improvement over the previous embodiment, to better protect the wire harness body 18, the rubber strip 13 is made of elastic rubber with a semi-circular cross-section. The spacing between adjacent rubber strips 13 is 2mm to 5mm. When the wire harness body 18 comes into contact with the rubber strip 13, the rubber strip 13 is compressed by 0.5mm to 1.5mm to enhance friction and provide cushioning. The advantage is that the semi-circular rubber strip 13, made of elastic rubber, deforms under pressure, tightly wrapping the wire harness body 18 with a compression of 0.5mm to 1.5mm. This increases friction to prevent the wire harness from shifting and reduces vibration damage to the wire harness through elastic cushioning.

[0044] Example 4:

[0045] like Figure 2 — Figure 11 As shown, as an improvement on the previous embodiment, to facilitate the assembly of the wire harness protective sleeve 9, the wire harness protective sleeve 10, and the wire clip 1 together, the hook block 21 has a shark tooth structure with serrated edges or multiple sharp tooth protrusions; hook blocks 21 are provided at the ends of the first alignment rod 11 and the second alignment rod 12. The advantage is that the shark tooth structure of the hook block 21 utilizes the meshing action of the serrated sharp teeth to form a mechanical self-locking effect, ensuring precise alignment between the first alignment rod 11 and the second alignment rod 12, effectively preventing lateral displacement of the wire harness protective sleeve after installation.

[0046] Specifically, the depth of the recess 2 is 80% to 90% of the height of the lower hook ring 20. The lower hook ring 20 has a "C" shape, and its opening direction is consistent with the arc direction of the recess 2. The advantages are that the interference fit between the lower hook ring 20 and the recess 2 forms an elastic snap-fit, the 80% to 90% depth matching ensures insertion stability, and the C-shaped opening direction matching the arc structure design makes it less likely for the wire harness protective sleeve 2 10 and wire harness protective sleeve 1 9 to fall off after being secured inside the wire clip 1, thus improving structural reliability.

[0047] Specifically, the overall width of the assembled wire harness protective sleeve 9 and wire harness protective sleeve 10 is equal to the internal width of the wire clip 1. This has the advantage of preventing the wire harness protective sleeve 10 and wire harness protective sleeve 9 from easily falling off after being secured inside the wire clip 1, thus improving structural reliability.

[0048] Example 5:

[0049] like Figure 2 — Figure 11 As shown, as an improvement over the previous embodiment, to better compress the wire harness body 18, the top of the pressure plate 4 adopts a concave arc-shaped structure, and the C-shaped opening of the upper through hole 19 faces the inside of the wire clip 1. The radii of the upper through hole 19 and the lower through hole 7 are consistent. The advantage is that the concave arc-shaped structure of the pressure plate 4 can evenly compress the wire harness body 18, and the rubber strip 13 will experience a compression of 0.5mm to 1.5mm, which ensures the fixing force while avoiding excessive compression of the wire harness. The design of keeping the radii of the upper through hole 19 and the lower through hole 7 consistent does not affect the installation of the locking bolt 8.

[0050] Working principle: In use, firstly, align the first alignment rod 11 on the outside of the wire harness protective sleeve 19 with the first adapter slot 14 and insert it. Then, align the second alignment rod 12 on the outside of the wire harness protective sleeve 20 with the second adapter slot 15 and insert it. Press the wire harness protective sleeve 19 and the wire harness protective sleeve 20 respectively, so that the hook blocks 21 with the shark tooth structure at the ends of the first alignment rod 11 and the second alignment rod 12 engage with each other to achieve hooking. Insert the lower hook ring 20 into the concave parts on both sides of the wire clip 1 and ensure that the insertion depth is equal to the height of the lower hook ring 20. When the wire harness is at 80% to 90% of its maximum capacity, the installation of wire harness protection sleeve 1, 9, and 10 can be completed. Then, use the locking bolt 8 to fix the wire clip 1 in the required installation position. Then, rotate the pivot 3 to open the pressure plate 4 and insert the wire harness body 18 into the inside of the wire harness protection sleeve 1, 9, and 10. The assembly is now complete. If expansion is required, the snap-fit ​​strip 17 of another wire clip 1 can be inserted into the snap-fit ​​slot 16 of the current wire clip 1 to achieve multi-unit assembly. The overall design is reasonable and the assembly is convenient.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
