[0002] In the design and assembly of modern air conditioning units and other equipment, a large number of screws are often required for fixing due to limited internal space. These screws are not only used to fix the outer sheet metal parts and electrical boxes, but also widely used to fix internal circuit boards and components. However, during installation, especially when routing wiring, due to the flexible nature of the wiring, even if it is required to tighten and fix it at every point, it is difficult to ensure consistency during production operations. Inevitably, the problem of wires touching screws will occur, resulting in the wires being cut or severed by the screws, affecting the normal operation of the equipment, and may even cause safety hazards.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0047] like Figures 1-8 As shown, the main structure of the wire securing device provided in this application embodiment includes a wire tie 100 and a protective part 200. The wire tie 100 includes a tie body 110 and a tightening part 120. One end of the tie body 110 is connected to the tightening part 120. The tightening part 120 is configured to allow the free end of the tie body 110 to pass through and tighten the bundled object. The protective part 200 is connected to the tightening part 120. The protective part 200 has a protective hole 210, which is configured to be fitted onto a screw 800.

[0048] The wire protection device of this embodiment aims to solve the problem of interference and wire cutting between screws 800 and electrical cables 900 during the assembly of equipment such as air conditioning units, thereby improving the reliability and safety of the equipment. The main structure of the wire protection device includes cable ties 100 and a protective part 200.

[0049] The main components of the cable tie 100 are the tie body 110 and the tightening part 120. One end of the cable tie 100 is fixedly connected to the tightening part 120, and the other end is a free end for operators to use when bundling cables 900. The tightening part 120 is designed as an adjustable locking device, which can wrap the free end of the tie body 110 around the electrical wiring and adjust it to a suitable tightness, thereby effectively bundling the wiring. The tightening part 120, through its groove or other locking design, ensures that the free end of the tie body 110 is stably fixed after passing through. The specific locking method of the tightening part 120 to the tie body 110 can refer to existing technology and will not be elaborated further. The material of the tie body 110 can be a flexible plastic or durable material such as nylon, capable of withstanding long-term tensile force and use. The length and width of the tie body 110 are determined according to the wiring requirements of the equipment and can accommodate cables 900 of different specifications.

[0050] During the assembly of the air conditioning unit, operators need to route the electrical wiring inside the casing 700. During this process, cable ties 100 are first used to bundle the tangled electrical cables 900 together. By passing the free end of the ties 110 through the tightening part 120 and adjusting it to the appropriate tightness, the cable ties 100 effectively tighten and secure the electrical wiring. The protective holes 210 on the protective part 200 are fitted onto the pre-installed screws 800 on the casing 700, specifically onto the tip and threaded section of the screws 800. This design of the protective part 200 effectively avoids interference between the screws 800 and the wiring, ensuring that there is no collision or cutting between the screws 800 and the wiring. In this process, the protective part 200 not only isolates the screws 800 from the electrical wiring but also provides additional securing effect through its cooperation with the screws 800, preventing the wiring from shaking or loosening inside the equipment and ensuring the stability and safety of the internal wiring.

[0051] The cable protection device provided in this embodiment effectively solves the problem of wire cutting caused by screw 800 interference between cable 900 and screw 800 during the assembly of equipment such as air conditioning units. The cable tie 100 effectively secures the wiring and frees up internal space within the housing 700. The protective part 200, by being fitted onto the screw 800, forms a physical barrier, ensuring that the wiring will not collide with the screw 800 and preventing wire cutting. The protective part 200 also further secures the wiring, reducing its movement within the unit, thereby improving the safety and reliability of the equipment.

[0052] In some implementations, such as Figure 1 As shown, the protective part 200 has a columnar structure, the cable tie 100 is disposed at one end of the protective part 200 in the axial direction, and the protective hole 210 includes a first protective hole 211 opened at the other end of the protective part 200 in the axial direction and extending along the axial direction of the protective part 200.

[0053] The protective part 200 adopts a columnar structure, which provides greater adaptability and stability. In this embodiment, the columnar shape of the protective part 200 facilitates insertion into the fixing holes of the housing 700. This allows the protective part 200 to assist in securing the wiring even without screws 800, through the cooperation between the columnar structure and the hole structure. This design is particularly suitable for areas of the housing 700 without screws 800, providing additional support, preventing the cable 800 from shifting or loosening in space, and improving flexibility during assembly.

[0054] Another significant feature of the protective part 200 is the axial extension design of the first protective hole 211. The first protective hole 211 extends along the axial direction of the protective part 200, effectively increasing its length and the contact area with the screw 800. This ensures a more stable physical isolation between the screw 800 and the electrical cable 900 during internal wiring. By increasing the length of the first protective hole 211, the protective part 200 provides stronger support between the screw 800 and the wiring, ensuring the stability of the wiring within the machine and preventing the cable 900 from shaking or loosening, effectively improving the long-term operational stability and safety of the equipment. (See also: Application scenarios where the columnar protective part 200 mates with the fixing holes on the housing 700, or where the first protective hole 211 mates with the screw 800 on the housing 700.) Figure 8 The fixed line protection device in the lower right corner.

[0055] In some implementations, such as Figures 1-5 and Figure 7 As shown, the outer surface of the protective part 200 is provided with a plurality of first locking parts 220 distributed along its axial direction. Each first locking part 220 is a protrusion circumferentially surrounding the protective part 200. The purpose of the first locking parts 220 is to enhance the fixing effect between the protective part 200 and the fixing hole after the columnar protective part 200 is inserted into the fixing hole, preventing the fixing part from coming out of the fixing hole. Specifically, the protruding structure of the first locking parts 220 will be squeezed and deformed when the protective part 200 is inserted into the fixing hole, thereby firmly fixing the connection between the protective part 200 and the fixing hole.

[0056] Preferred, such as Figure 4 As shown, the side of the first locking portion 220 facing the cable tie 100 has a first plane 221 perpendicular to the axial direction of the protective portion 200, while the side of the first locking portion 220 away from the cable tie 100 has an inclined second plane 222. As the second plane 222 extends radially outward along the protective portion 200, it gradually approaches the first plane 221, thus forming a wedge-shaped surface. During the insertion of the protective portion 200 into the fixing hole, the wedge-shaped design of the second plane 222 allows the protective portion 200 to be inserted into the fixing hole relatively easily, while the first plane 221 effectively prevents the protective portion 200 from coming out of the fixing hole. The wedge-shaped design of the second plane 222 makes the insertion of the protective portion 200 into the fixing hole smoother, reducing resistance during installation and improving installation efficiency; it also effectively locks the position of the protective portion 200 through the flat structure of the first plane 221, preventing loosening of the protective portion 200 due to vibration, external force, or prolonged use, ensuring a secure fixation effect.

[0057] In some implementations, such as Figures 1-7As shown, the protective part 200 has a plurality of slits 230 in the circumferential direction. Each slit 230 extends from the free end of the protective part 200 along the axial direction of the protective part 200, and each slit 230 penetrates radially to the first protective hole 211. These slits 230 divide the protective part 200 into a plurality of petal-shaped structures in the circumferential direction.

[0058] The design of the slit 230 enables the protective part 200 to have sufficient elastic deformation capacity, allowing the protective part 200 to elastically deform according to the actual situation during installation, adapting to fixing holes or screws 800 of different sizes, improving the fault tolerance of installation, and avoiding problems of insecure fixing caused by mismatched hole diameters or installation errors.

[0059] For example, when the protective part 200 is inserted into the fixing hole, it is squeezed by the wall of the fixing hole, causing it to deform radially inward. This enhances the connection between the protective part 200 and the fixing hole, preventing it from falling off or loosening. This design improves adaptability during installation; even if there is a certain error in the size of the fixing hole, the protective part 200 can still be reliably fixed.

[0060] For example, when the first protective hole 211 of the protective part 200 is fitted onto the pre-installed screw 800 inside the machine, the protective part 200 is compressed by the screw 800, causing it to deform radially outward. This radial outward deformation allows the protective part 200 to make better contact with the screw 800. The radial deformation enhances the friction between the contact surfaces of the protective part 200 and the screw 800, improving the connection between them. This design not only effectively isolates the cable 900 from direct contact with the screw 800, avoiding wire cutting issues, but also ensures a tight connection between the protective part 200 and the screw 800, improving the stability of the equipment.

[0061] In some implementations, such as Figure 1 As shown, the first protective hole 211 has a plurality of second locking portions 240 distributed along its axial direction on its wall surface. The second locking portions 240 are circumferentially surrounding protrusions. The protruding structure of the second locking portions 240 cooperates with the slit 230 structure of the protective portion 200, providing a more stable connection after the screw 800 is inserted into the protective portion 200. When the first protective hole 211 of the protective portion 200 is fitted onto the screw 800, the screw 800, through cooperation with the second locking portions 240, forms a stronger physical contact between the protective portion 200 and the screw 800, thereby enhancing the friction and connection stability between the protective portion 200 and the screw 800, preventing the protective portion 200 from falling off due to vibration or external force, thus maintaining effective isolation between the screw 800 and the cable 900, and avoiding the risk of the screw 800 cutting the cable.

[0062] In some implementations, such as Figure 1 , Figures 3-5 and Figure 7 As shown, the protective hole 210 further includes a second protective hole 212 formed on the circumferential surface of the protective part 200 and extending radially along the protective part 200. The first protective hole 211 and the second protective hole 212 can respectively form a protective effect in two directions, enhancing the adaptability of the wire protection device. Specifically, the first protective hole 211 extends axially along the protective part 200 and is configured to be sleeved on the screw 800 along the axial direction of the protective part 200, completely covering the tip and threaded section of the screw 800, preventing the screw 800 from directly contacting the wiring. During installation, it is suitable for situations where the exposed end of the screw 800 is perpendicular to the wiring. The second protective hole 212 extends radially along the protective part 200 and is formed on the circumferential surface of the protective part 200. It is configured to be sleeved on the screw 800 radially along the protective part 200, laterally covering the screw 800. During installation, it is suitable for situations where the exposed end of the screw 800 is parallel to the wiring. Application scenarios where the second protective hole 212 mates with the screw 800 on the housing 700. Figure 8 The fixed line protection device in the upper left corner.

[0063] Users can choose to use either the first protective hole 211 or the second protective hole 212 based on the specific positional relationship between the screw 800 and the wiring inside the device. When the screw 800 is arranged roughly parallel to the wiring direction, the second protective hole 212 of the protective part 200 can be fitted onto the screw 800 for protection; when the screw 800 is arranged roughly perpendicular to the wiring, the first protective hole 211 can be fitted onto the screw 800 for protection. The combined design of the first protective hole 211 and the second protective hole 212 can adapt to different arrangements of the screw 800 and the wiring, significantly improving the applicability of the wire protection device. Users can quickly select the appropriate protective hole 210 according to the actual installation environment, reducing adjustment steps during assembly and improving assembly efficiency.

[0064] In some embodiments, the second protective hole 212 of the wire protection device penetrates the protective portion 200 radially, meaning that the second protective hole 212 forms openings at both radial ends of the protective portion 200. This embodiment further optimizes the adaptability of the wire protection device by proposing a design for a second protective hole 212 that radially penetrates the protective portion 200, thereby improving the flexibility of the device in different installation environments and enabling users to complete the installation more conveniently. In this embodiment, the protective portion 200 is still a columnar structure, but compared to the aforementioned embodiments, the second protective hole 212 penetrates the protective portion 200 radially, forming openings at both radial ends of the protective portion 200. This allows users to select the opening closer to the screw 800 for fitting based on spatial location, improving installation convenience. When the screw 800 is substantially perpendicular to the wiring, the first protective hole 211 is used for axial fitting, and the screw 800 is completely enclosed within the protective portion 200. When screw 800 is roughly parallel to the wiring, radial fitting is performed using the second protective hole 212, and the end closer to screw 800 is selected for installation. Users are not limited to a single direction and can choose the most convenient end for installation based on the spatial layout. This is suitable for situations where the positions of screw 800 and cable 900 are limited, especially in confined spaces, thus improving the device's compatibility.

[0065] In some implementations, such as Figures 3-4As shown, the second protective hole 212 has a plurality of convex ribs 250 spaced apart circumferentially along the hole wall, and the convex ribs 250 extend axially along the second protective hole 212. The spaced convex ribs 250 deform when pressed by the screw 800, which can improve the connection effect between the screw 800 and the protective part 200. In the preceding embodiments, a plurality of second locking portions 240 distributed axially are provided on the wall surface of the first protective hole 211. The second locking portions 240 are circumferentially arranged protrusions. The interference effect between the circumferentially arranged protrusions and the threads of the screw 800 is too strong, resulting in great resistance during assembly and making assembly difficult. However, since a plurality of slits 230 are distributed circumferentially in the first protective hole 211, when the first protective hole 211 is fitted onto the screw 800, the circumferential protective portion 200 of the first protective hole 211 will deform outward, which can balance the obstructive effect of the protruding structure of the second locking portions 240. With the synergistic effect of the second locking portions 240 and the slits 230, sufficient connection firmness can be obtained, and the assembly process of the first protective hole 211 and the screw 800 can be made easier. However, in this embodiment, since the second protective hole 212 is radially opened on the columnar protective part 200, it is impossible to set a structure similar to the crack 230 around the second protective hole 212. Otherwise, the strength of the protective part 200 cannot be guaranteed, which makes the deformation capacity of the protective part 200 around the second protective hole 212 weak. If a circumferential protrusion is set on the wall surface of the second protective hole 212, it will cause excessive interference with the thread of the screw 800, resulting in greater assembly resistance. Therefore, in this embodiment, the protrusion 250 extends along the axial direction of the second protective hole 212 (i.e., the radial direction of the protective part 200). During the process of fitting the second protective hole 212 onto the screw 800, the protrusion 250 extending along the axial direction of the second protective hole 212 helps to reduce the resistance during the assembly process, and the deformation of the protrusion 250 after being squeezed can increase the connection firmness between the screw 800 and the protective part 200.

[0066] This embodiment addresses the assembly resistance issue of the second protective hole 212 by proposing an axially distributed ridge 250 structure, cleverly avoiding the problem that the slit 230 structure is unsuitable for the second protective hole 212. Furthermore, it also reduces assembly resistance and enhances the fixing effect of the screw 800.

[0067] In wire protection devices, the connection method between the cable tie 100 and the protective part 200 needs to be flexible to adapt to different installation environments. For example, when the position or orientation of the screw 800 is different, the orientation of the second protective hole 212 on the protective part 200 needs to be adjusted to better fit onto the screw 800. Based on this, in some embodiments, such as Figures 1-8As shown, the wire securing and protection device further includes a first connector 300 connected to the cable tie 100 and a second connector 400 connected to the protective part 200. The first connector 300 and the second connector 400 are rotatably engaged. A first locking member 310 is provided on the first connector 300, and a second locking member 410 is provided on the second connector 400. The wire securing and protection device has a locked state and an unlocked state. In the locked state, the first locking member 310 and the second locking member 410 are locked together to restrict the relative rotation of the first connector 300 and the second connector 400. In the unlocked state, the first locking member 310 and the second locking member 410 are unlocked, and the first connector 300 and the second connector 400 can rotate relative to each other. This embodiment allows the cable tie 100 and the protective part 200 to be rotatably engaged and has locking and unlocking functions, making it convenient for users to adjust the orientation of the protective part 200 according to actual installation needs.

[0068] The axis of rotation of the rotational fit formed between the first connector 300 and the second connector 400 is preferably parallel to the axial direction of the protective part 200, which facilitates the adjustment of the angle of the second protective hole 212 on the protective part 200. The first locking member 310 provided on the first connector 300 and the second locking member 410 provided on the second connector 400 can lock or unlock each other, thereby restricting or allowing relative rotation between the first connector 300 and the second connector 400. This wire-fixing protection device can switch between two states. In the locked state, the first locking member 310 and the second locking member 410 are locked together to prevent relative rotation between the first connector 300 and the second connector 400, thereby fixing the angle of the protective part 200. This is suitable for situations where a stable connection needs to be maintained after the direction of the protective part 200 has been determined. In the unlocked state, the first locking member 310 and the second locking member 410 are unlocked, and the first connector 300 and the second connector 400 can rotate freely relative to each other. The user can adjust the orientation of the second protective hole 212 on the protective part 200 to accommodate screws 800 in different directions.

[0069] This embodiment provides a more flexible wire protection device through the rotatable connection between the cable tie 100 and the protective part 200, combined with a lockable / unlockable design. This design allows the user to freely adjust the orientation of the second protective hole 212 during installation, thereby accommodating screws 800 in different directions, improving installation flexibility and ease of use.

[0070] In some embodiments, both the first connector 300 and the second connector 400 are cylindrical sleeve structures. The second connector 400 is coaxially sleeved on the outside of the first connector 300. The second locking member 410 consists of locking holes circumferentially distributed on the second connector 400, and the first locking member 310 is a locking protrusion protruding from the outer wall of the first connector 300. The first connector 300 is made of a material with a certain degree of elasticity, such as plastic or rubber. During use, pressing the locking protrusion can deform the first connector 300 and cause it to recess towards the center. After releasing the locking protrusion, the first connector 300 causes the locking protrusion to spring back to its original position.

[0071] The cable tie protection device employs a coaxial cylindrical sleeve structure combined with an elastic locking mechanism. The locking protrusion and locking hole work together to achieve convenient rotational adjustment and locking, ensuring that the connection between the cable tie 100 and the protective part 200 can be rotated and adjusted while also being stably locked in a set position. The first connecting member 300 is made of elastic material, giving it deformable properties. During unlocking, the user presses the locking protrusion, causing the first connecting member 300 to deform inwards towards the center, thus disengaging the locking protrusion from the locking hole and allowing the second connecting member 400 to rotate relative to it. During locking, after releasing the pressure, the first connecting member 300 automatically springs back to its original position due to the material's elasticity, causing the locking protrusion to re-embed into the locking hole, thereby completing the locking process.

[0072] By pressing the locking protrusion, users can freely rotate and adjust the angle of the protective part 200° to adapt to the orientation of the screws 800° in different installation environments. The press-to-unlock and release-to-lock design allows for easy adjustment and fixation without additional tools. The coaxial sleeve structure ensures smooth rotation without loosening, balancing stability and ease of operation for an enhanced user experience.

[0073] In some embodiments, the first connector 300 has a perforated portion 320, which is distributed on both sides of the locking protrusion. In the rotational adjustment design of the wire protection device, ease of unlocking is crucial. This embodiment, by providing perforated portions 320 on both sides of the locking protrusion of the first connector 300, further reduces the operating force required for pressing to unlock, making rotational adjustment smoother.

[0074] The shape and size of the cutout 320 can be optimized according to material properties and deformation requirements. Common forms include elongated, elliptical, or other open structures. Because the cutouts 320 are provided on both sides of the locking protrusion, the first connector 300 part where the locking protrusion is located is more likely to deform when pressed, and is more likely to deform inward towards the center, causing the locking protrusion to disengage from the locking hole, thereby unlocking smoothly and reducing the force required to unlock by pressing.

[0075] In some implementations, such as Figures 1-8 As shown, a baffle plate 500 is provided between the protective part 200 and the second connecting member 400. The baffle plate 500 is arranged perpendicular to the axial direction of the protective part 200. When the protective part 200 is inserted into the fixing hole or the first protective hole 211 is fitted onto the screw 800, the baffle plate 500 is parallel to the housing where the fixing hole or screw 800 is located. At this time, the baffle plate 500 can separate the cable fixed by the cable tie 100 from other screws 800 or metal structures on the housing 700, avoiding problems such as wear, short circuit or electromagnetic interference caused by contact. Preferably, the baffle plate 500 forms a cutting part 510 on the side where the second protective hole 212 is opened. The cutting part 510 is flush with the outer edge of the second connecting member 400. The setting of the second cutting part 510 ensures that when the second protective hole 212 is fitted onto the screw 800, the baffle plate 500 will not interfere with the housing 700 and will not affect the fitting of the second protective hole 212 onto the screw 800.
