Description

Technical Field

[0001] The present application relates to the technical field of wire harness fixing, and in particular to a staggered fir-tree type fastener structure. Background Art

[0002] In the automotive industry, the fixation of wire harnesses is a crucial technology. As a core component of the internal electrical system of a car, the direction, fixed position and stability of the wire harness are directly related to the safety and functionality of the car. Therefore, the fixing direction of the automotive wire harness has become an issue that must be seriously considered. The correct fixing direction can ensure the fastening effect and fixing performance of the wire harness, prevent interference and damage between the wire harness and surrounding parts, and prevent noise caused by back and forth movement. In practical applications, cable ties in horizontal, vertical, oblique, loop and cross directions are widely used in the fixation of automotive wire harnesses.

[0003] In the related technology, the existing automotive wiring harness fixing technology has achieved certain results, but there are still some problems in practical application; for example, some traditional fastener structures may require a large insertion force when fixing the wiring harness, which not only increases the difficulty of installation, but may also cause damage to the wiring harness or the fastener itself, so it needs to be improved. Utility Model Content

[0004] In order to solve the problem that traditional fasteners are difficult to install, the present application provides a staggered fir tree type fastener structure.

[0005] The present application provides a staggered fir-tree type fastener structure that adopts the following technical solution:

[0006] A staggered fir tree type fastener structure comprises a tie portion and an undercut portion, wherein the undercut portion is connected to the bottom of the tie portion, the undercut portion is in a fir tree-shaped structure, a plurality of undercut units are arranged on the undercut portion, and the plurality of undercut units are arranged in a staggered manner along the central axis direction of the undercut portion, a connecting component is arranged between the tie portion and the undercut portion, the connecting component comprises a dustproof disc and a connecting block, the dustproof disc is arranged at one end of the undercut portion close to the tie portion, the dustproof disc is in an umbrella-shaped structure, the undercut portion is connected to one end of the dustproof disc, the connecting block is connected to the other end of the dustproof disc, and the tie portion is connected to the connecting block.

[0007] Since some traditional fastener structures may require a large insertion force when fixing the wiring harness, this not only increases the difficulty of installation, but may also cause damage to the wiring harness or the fastener itself; by adopting the above technical solution, including a tie portion and a buckle portion, a plurality of buckle units are integrally formed on the buckle portion, and the buckle units are staggered and arranged on the buckle portion, and at the same time, a connecting component is installed between the tie portion and the buckle portion, and the connecting component includes a dustproof disc and a connecting block; when the wiring harness needs to be fixed, the tie portion is first placed in an appropriate position, and then the buckle portion is aligned and pressed into a predetermined hole or fixing point by some means (possibly finger push or other installation tools). Since the buckle units are staggered, the insertion force is reduced, and the buckle units are staggered. The fir-tree-shaped structure of the buckle helps to increase the friction between the fastener and the fixing point, making it more difficult to pull out; through the settings of the undercut portion, undercut unit and connecting assembly, the fir-tree-shaped structure of the undercut portion increases the friction between the fastener and the fixing point, making the fastener more difficult to pull out, thereby improving the stability of the fixation, and the staggered arrangement design of the undercut unit helps to reduce the insertion force, making the installation of the fastener easier, while also reducing potential damage to the wiring harness or the fastener itself. At the same time, the dustproof disc and connecting block in the connecting assembly play a role in strengthening the connection and dustproofing, and can effectively prevent dust or debris from entering the gap between the fastener and the fixing point, thereby maintaining the long-term stability and reliability of the fastener.

[0008] Optionally, a tip unit for facilitating insertion is provided at the end of the undercut portion, and the tip unit is arranged at an end of the undercut portion away from the cable tie portion.

[0009] By adopting the above technical solution, the tip unit is integrally formed on the undercut portion; through the setting of the tip unit, the design of the tip unit enables the undercut portion to have better guidance during insertion, and since the tip unit is relatively thin, it can pass through the hole or fixed point more easily, thereby reducing the difficulty of insertion.

[0010] Optionally, an adjustment notch for improving anti-rotation capability is provided on the undercut portion, and the adjustment notch is provided along the length direction of the undercut portion.

[0011] By adopting the above technical solution, an adjustment notch is opened on the undercut part; by adjusting the setting of the notch, it helps to improve the anti-rotation ability of the undercut part when subjected to external force. In some application scenarios that need to withstand torsion or rotational force, it can effectively reduce the risk of the fastener loosening or falling off. At the same time, the adjustment notch makes the undercut part have a certain elasticity, which makes it easier to insert or pull out the undercut part from the fixed point when installing or removing the fastener, thereby improving the convenience of installation and disassembly.

[0012] Optionally, the tie portion includes a tie head and a tie body, the tie head is arranged on one side of the connecting block, the connecting block is provided with a connecting groove for the tie body to pass through, the tie head is provided with a through groove, one end of the tie body is connected to the tie head, and the other end of the tie body passes through the inner wall of the connecting groove and the inner wall of the through groove in sequence, the tie body is provided with a plurality of locking grooves along the length direction, and a locking block for cooperating with the inner wall of the locking groove is provided in the through groove of the tie head.

[0013] By adopting the above technical solution, the cable tie portion includes a cable tie head and a cable tie body; when the wire harness needs to be fixed, the wire harness is placed at the position to be fixed, the unconnected end of the cable tie body passes through the connecting groove and the through groove until its end is exposed, and the unconnected end of the cable tie body is pulled to make it tight and surround the wire harness. At this time, the unconnected end of the cable tie body is pulled to the locking block position, and the locking block will cooperate with one of the inner walls of the locking grooves to fix the position of the cable tie and complete the fixation of the wire harness; the arrangement of the cable tie head and the cable tie body helps to facilitate the fixation of the wire harness, without the need for additional tools or complicated operating steps, greatly improving the convenience of fixing the wire harness, and ensuring reliable fixation to ensure that the wire harness will not loosen or fall off when subjected to external force. At the same time, the length of the cable tie body can be adjusted as needed, with good practicality and can meet various fixing needs.

[0014] Optionally, a protrusion is provided at one end of the cable tie head, and a recessed groove for fixing the protrusion is provided at one side of the connecting block.

[0015] By adopting the above technical solution, the protrusion is integrally formed on the cable tie head, and a recessed groove is provided on the connecting block, and the protrusion is matched with the inner wall of the recessed groove; by setting the protrusion and the recessed groove, the position of the cable tie head is ensured to be accurate, which not only simplifies the installation process but also improves the stability of the installation.

[0016] Optionally, a plane portion for supporting the wiring harness is provided on the connection block, and the plane portion is connected to an end of the connection block away from the dustproof disc.

[0017] By adopting the above technical solution, the planar portion is integrally formed on the top of the connecting block; through the setting of the planar portion, the design of the planar portion allows the wiring harness to be stably placed thereon, thereby reducing the possibility of shaking or moving the wiring harness, helping to keep the wiring harness neatly arranged, and at the same time providing a certain degree of protection for the wiring harness, thereby extending the service life of the wiring harness.

[0018] Optionally, a through hole is formed through the planar portion of the connecting block, and an inner wall of the through hole is connected to an inner wall of the connecting groove.

[0019] By adopting the above technical solution, a through hole is opened through the plane part; through the provision of the through hole, in the scenario where the cable tie is fixed, the possibility of the cable tie body getting stuck when passing through the connecting groove can be reduced, and the cable tie body can be moved to achieve more flexible operation.

[0020] Optionally, a trapezoidal rib plate for enhancing structural strength is provided between the undercut portion and the dustproof disc, and the trapezoidal rib plate is connected between the undercut portion and the dustproof disc.

[0021] By adopting the above technical solution, the trapezoidal rib plate is welded and fixed between the undercut part and the dustproof disc; through the setting of the trapezoidal rib plate, the overall rigidity and strength of the structure can be increased, the stress can be effectively dispersed, and the structure can be prevented from being cracked or damaged in the stress concentration area, so that it can withstand greater external forces and pressures, thereby improving the service life and safety of the product.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] Through the arrangement of the undercut part, undercut unit and connection assembly, the fir-tree-shaped structure of the undercut part increases the friction between the fastener and the fixing point, making it more difficult to pull out the fastener, thereby improving the stability of the fixation. The staggered arrangement design of the undercut unit helps to reduce the insertion force, making the installation of the fastener easier, while also reducing the potential damage to the wiring harness or the fastener itself. At the same time, the dustproof disc and the connection block in the connection assembly play a role in strengthening the connection and dustproofing, and can effectively prevent dust or debris from entering the gap between the fastener and the fixing point, thereby maintaining the long-term stability and reliability of the fastener.

[0024] By setting the tip unit, the design of the tip unit makes the undercut part have better guidance during insertion. Since the tip unit is relatively thin, it can pass through the hole or the fixing point more easily, thereby reducing the difficulty of insertion;

[0025] The arrangement of the cable tie head and the cable tie body facilitates the fixing of the wire harness without the need for additional tools or complicated operating steps, greatly improving the convenience of fixing the wire harness. The fixation is reliable, ensuring that the wire harness will not loosen or fall off when subjected to external force. At the same time, the length of the cable tie body can be adjusted as needed, which is practical and can meet various fixing needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Reference Figure 1 and Figure 3 The tie portion 1 includes a tie head 6 and a tie body 7. The tie head 6 is installed on one side of the connecting block 5. A connecting groove 51 is penetrated on the connecting block 5. A through groove 61 is penetrated on the tie head 6. One end of the tie body 7 is installed and fixed on the tie head 6, and the other end of the tie body 7 passes through the inner walls of the connecting groove 51 and the through groove 61 in sequence.

[0035] Reference Figure 1 and Figure 3A plurality of locking grooves 71 are formed on the cable tie body 7, and the plurality of locking grooves 71 are formed in sequence along the length direction of the cable tie body 7. A locking block 62 is installed in the through groove 61 of the cable tie head 6. The wiring harness is placed at the position where it needs to be fixed, and the unconnected end of the cable tie body 7 passes through the connecting groove 51 and the through groove 61 until its end is exposed. The unconnected end of the cable tie body 7 is pulled to tighten it and surround the wiring harness. At this time, the unconnected end of the cable tie body 7 is pulled to the position of the locking block 62, and the locking block 62 cooperates with the inner wall of one of the locking grooves 71 to fix the position of the cable tie and complete the fixation of the wiring harness to ensure that the wiring harness will not loosen or fall off when subjected to external force. At the same time, the length of the cable tie body 7 can be adjusted as needed, which has good practicality and can meet various fixing requirements.

[0036] Reference Figure 2 A protrusion 63 is integrally formed at one end of the cable tie head 6, and a recessed groove 52 is provided on one side of the connecting block 5. In this embodiment, the protrusion 63 is matched with the inner wall of the recessed groove 52 to ensure that the position of the cable tie head 6 is accurate, which not only simplifies the installation process but also improves the stability of the installation.

[0037] Reference Figure 3 A flat portion 53 is integrally formed on the top of the connecting block 5, and the flat portion 53 is a disc-shaped structure. The design of the flat portion 53 allows the wire harness to be stably placed thereon, thereby reducing the possibility of shaking or moving the wire harness, helping to keep the wire harness neatly arranged, and at the same time providing a certain degree of protection for the wire harness, thereby extending the service life of the wire harness.

In some application scenarios that need to withstand torsion or rotational force, the risk of the fastener loosening or falling off can be effectively reduced. At the same time, the adjustment slot 23 makes the undercut portion 2 have a certain elasticity, which makes it easier to insert or pull out the undercut portion 2 from the fixed point when installing or removing the fastener, thereby improving the convenience of installation and removal.

[0042] The implementation principle of the staggered fir-tree type fastener structure of the embodiment of the present application is as follows: when the wire harness needs to be fixed, the tie portion 1 is first placed in an appropriate position, and then the undercut portion 2 is aligned and pressed into a predetermined hole or fixing point by some means (possibly finger push or other installation tools), the wire harness is placed in the position to be fixed, the unconnected end of the tie body 7 passes through the connecting groove 51 and the through groove 61 until its end is exposed, and the unconnected end of the tie body 7 is pulled to tighten and surround the wire harness. At this time, the unconnected end of the tie body 7 is pulled to the position of the locking block 62, and the locking block 62 will cooperate with the inner wall of one of the locking grooves 71, thereby fixing the position of the tie , completing the fixation of the wiring harness; through the settings of the undercut portion 2, the undercut unit 21 and the connecting component 3, the fir-tree-shaped structure of the undercut portion 2 increases the friction between the fastener and the fixing point, making the fastener more difficult to be pulled out, thereby improving the stability of the fixation, and the staggered arrangement design of the undercut unit 21 helps to reduce the insertion force, making the installation of the fastener easier, while also reducing the potential damage to the wiring harness or the fastener itself, while the dustproof disc 4 and the connecting block 5 in the connecting component 3 play a role in strengthening the connection and dustproofing, and can effectively prevent dust or debris from entering the gap between the fastener and the fixing point, thereby maintaining the long-term stability and reliability of the fastener.
