Description

Technical Field

[0001] This disclosure relates to the field of electrical technology, and in particular to a screw-in assembly, a wire fixing device, and an electrical device. Background Technology

[0002] Currently, electrical appliances such as air conditioners on the market often involve wiring paths, and there are often sheet metal parts or PCB boards (circuit boards) that need to be fixed with screws. When there are wires near these screws, in order to avoid the wires passing through the top of the screws (such as screw heads or bolt heads) and rubbing against the burrs on them, causing insulation damage, a fixation is usually added at a certain distance from the screws so that the wires do not pass through the location of the screws. However, this method increases the wiring path, resulting in increased wiring length and cost, and it also makes it impossible to freely choose the direction of the wires, leading to inconvenience in use.

The mounting platform is mounted at the location of the screw-in device, and the wire-fixing structure is mounted on the mounting platform and used to fix the wire. In the axial direction of the screw-in device, the wire-fixing position of the wire-fixing structure is spaced apart from the screw-in device. This arrangement can prevent the wire fixed on the wire-fixing structure from contacting the screw-in device, thereby preventing the wire at the location of the screw-in device from contacting the top of the screw-in device, thus preventing burrs on the top of the screw-in device from causing damage to the wire. It also avoids increasing the number of wiring paths, reducing wire length and cost. Furthermore, the wire-fixing structure and the mounting platform are movably connected, allowing the wire-fixing structure to move relative to the mounting platform.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] The following disclosure provides numerous different embodiments or examples for implementing various aspects of the present invention.

Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0051] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0052] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application.

[0053] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0054] To address the technical problem of inconvenient wiring at the location of screw-in devices in the prior art, this disclosure provides a screw-in assembly, a wire fixing device, and an electrical device.

[0055] In this disclosure, the screw-in assembly may include a screw-in device and a wire-fixing device. The wire-fixing device may include a mounting platform and a wire-fixing structure. The mounting platform is positioned at the location of the screw-in device, and the wire-fixing structure is mounted on the mounting platform and used to fix the wire. Along the axial direction of the screw-in device, the wire-fixing positions of the wire-fixing structure are spaced apart from the screw-in device. This arrangement avoids contact between the wire fixed on the wire-fixing structure and the screw-in device, thereby preventing contact between the wire at the location of the screw-in device and the top of the screw-in device. This prevents damage to the wire caused by burrs on the top of the screw-in device and avoids adding excessive wiring paths, reducing wire length and cost. Furthermore, the wire-fixing structure and the mounting platform are movably connected, allowing the wire-fixing structure to move relative to the mounting platform. This movement of the wire-fixing structure relative to the mounting platform can change the routing direction of the wire fixed on the wire-fixing structure, further facilitating wire placement and providing convenience for wiring. In other words, this disclosure can not only protect the line from damage caused by the burrs of the screw connection device, but also avoid increasing the number of wiring paths, reduce the length and cost of the line, and make it easier to adjust the wiring direction, making the wiring more convenient and improving the ease of wiring.

[0056] In one exemplary embodiment, a wire securing device and a screw assembly having the wire securing device provided are provided. (See reference...) Figure 1 , Figure 2 and Figure 5 As shown, the screw assembly 10 may include a screwing device 2 in addition to the wire fixing device 1. The screwing device 2 may include a screw and nut, or a bolt and nut, or other devices that can achieve screwing, without limitation.

[0057] The cable fixing device 1 includes a mounting platform 12 and a cable fixing structure 11. The mounting platform 12 is mounted at the location of the screw connection device 2, and the cable fixing structure 11 is mounted on the mounting platform 12. The cable fixing structure 11 is used to fix the line 20. Based on this, the cable can be arranged at the location of the screw connection device 2.

[0058] In this screw-connection assembly 10, the fixing position of the wire fixing structure 11 is spaced apart from the screw-connection device 2 along the axial direction of the screw-connection device 2. Based on this, the wire 20 located at the screw-connection device 2 can be separated from the screw-connection device 2, thereby avoiding damage to the wire 20 caused by burrs on the top of the screw-connection device 2, and also avoiding increasing the diameter of the wire 20 excessively, thus reducing the length and cost of the wire 20.

[0059] The fixed structure 11 is movably connected to the mounting platform 12 to allow the fixed structure 11 to move relative to the mounting platform 12. This relative movement of the fixed structure 11 and the mounting platform 12 changes the routing direction of the line 20. In other words, in this screw-connection assembly 10, the routing direction of the line 20 at the location of the screw-connection device 2 can be adjusted by the relative movement of the fixed structure 11 and the mounting platform 12, thereby further facilitating the installation of the line 20 and providing convenience for its routing.

[0060] In this embodiment, the fixing position of the wire fixing structure 11 and the screw connection device 2 are axially spaced apart. The wire 20 is fixed on the wire fixing structure 11, and a safe distance is maintained between it and the burrs on the top of the screw connection device 2, avoiding damage to the insulation layer of the wire 20 due to long-term friction. This significantly improves the safety and reliability of the wire 20. Moreover, there is no need to increase the length and cost of the wire 20 by routing the wire around the screw connection device 2. In other words, this embodiment can reduce the length and cost of the wire 20. In addition, this embodiment can adjust the routing direction by moving the wire fixing structure 11 on the mounting platform 12, thereby better optimizing the path of the wire 20, making the layout of the wire 20 easier, and further shortening the wire diameter, further reducing the wiring length, and reducing the cost of wire materials and installation time. Furthermore, since the routing direction can be adjusted, if it is necessary to change the layout of the wire 20 during equipment maintenance, in some cases the wire fixing structure 11 can be moved relative to the mounting platform 12 to adjust the wire 20, making maintenance easier.

[0061] In one exemplary embodiment, a wire securing device and a screw-on assembly having the wire securing device described above are provided. (See reference...) Figures 1 to 5 As shown, in this embodiment, the wire fixing structure 11 may include a wire fixing part 111 and a movable part 112 connected to each other. The wire fixing part 111 is used to fix the line 20, and the movable part 112 is used to be movably connected to the mounting platform 12.

[0062] The placement platform 12 includes a mating part 121 that cooperates with the movable part 112. The movable part 112 and the mating part 121 cooperate to achieve a movable connection between the fixed structure 11 and the placement platform 12. It should be noted that the relative movement between the movable part 112 and the mating part 121 can be relative sliding, relative rolling, or other forms of relative movement, and is not limited thereto.

[0063] In this configuration, one component of the movable part 112 and the mating part 121 includes a sphere, and the other component of the movable part 112 and the mating part 121 includes a groove 100. For example, the movable part 112 may include a sphere, and the mating part 121 may include a groove 100. As another example, the movable part 112 may include a groove 100, and the mating part 121 may include a sphere.

[0064] The ball is inserted into the slide groove 100 to slide within it. This embodiment allows for better movement of the fixed structure 11 relative to the mounting platform 12 by sliding the ball in the slide groove 100. Furthermore, the cooperation between the ball and the slide groove 100 can better reduce friction between them, ensuring convenient relative movement.

[0065] The cross-section of the slide groove 100 can be adapted to fit the sphere. For example, the cross-section of the slide groove 100 can be circular, with a diameter slightly larger than the diameter of the sphere, to facilitate the sliding of the sphere within the slide groove 100. Additionally, the slide groove 100 may include an inlet 300 for engaging the sphere. When the wire-fixing structure 11 needs to be installed on the mounting platform 12, the sphere can be engaged into the slide groove 100 through the inlet 300, and then the sphere can be slid within the slide groove 100 to achieve a movable connection between the sphere and the slide groove 100.

[0066] In some implementations...

[0067] The movable part 112 may include a sphere. The sphere and the wire fixing part 111 may be integrally formed or fixedly connected by welding, bonding or other means, which is not limited. The mating part 121 includes a groove 100. The cross-section of the groove 100 is adapted to the sphere, and the size of its groove opening is smaller than the diameter of the sphere. Based on this, the sphere can slide stably in the groove 100 without falling off. In addition, in order to facilitate the sphere to be inserted into the groove 100, an inlet 300 for the sphere is provided on the groove 100. The inlet 300 may be a circular opening, and the vertical drop of the circular opening may be slightly larger than the diameter of the sphere, so as to facilitate the sphere to be inserted into the groove 100. The sphere can be inserted into or detached from the groove 100 through the aforementioned circular opening. In this embodiment, the wire fixing device 1 can realize the movement of the wire fixing structure 11 relative to the mounting platform 12 through the cooperation of the sphere and the groove 100, thereby realizing the adjustment of the wire routing direction.

[0068] The mounting platform 12 can be constructed as a ring platform, and the movable connection between the wire fixing structure 11 and the mounting platform 12 allows the wire fixing structure 11 to rotate 360° along the ring platform. For example, a slide 100 can be provided on the ring platform, and the slide 100 extends circumferentially along the ring platform to form a ring-shaped slide 100. The sphere of the wire fixing structure 11 can then slide along the ring-shaped slide 100, thereby achieving a 360° rotation of the wire fixing structure 11 relative to the mounting platform 12, and thus achieving a 360° adjustment of the wiring direction.

[0069] This embodiment, through the movable connection between the ball and the slide 100, can greatly improve the flexibility of wiring, structural reliability, and ease of installation, effectively solving the problems of difficult wiring and high cost in the area 2 of traditional screw-connected devices.

[0070] It should be noted that, in addition to the movable connection between the wire fixing structure 11 and the mounting platform 12 achieved through the cooperation of the sphere and the groove 100, other methods can also be used, and there is no limitation on this. For example, when the mounting platform 12 is an annular platform, a cylindrical strip extending circumferentially along the annular platform can be provided on the annular platform, and a matching groove adapted to the cylindrical strip can be provided on the wire fixing structure 11. The wire fixing structure 11 can achieve 360° rotation relative to the mounting platform 12 through the sliding of the matching groove relative to the cylindrical strip, thereby achieving 360° adjustment of the wire routing direction.

[0071] In one exemplary embodiment, a wire securing device and a screw assembly having the wire securing device provided are provided. (See reference...) Figures 1 to 5 As shown, in this embodiment, the wire fixing part 111 includes a wire fixing frame 1111 with an opening, and a first wire fixing rib 1112 and a second wire fixing rib 1113 are provided inside the wire fixing frame 1111. The first wire fixing rib 1112 and the second wire fixing rib 1113 cooperate to fix the line 20.

[0072] In this embodiment, the first wire-fixing rib 1112 is connected to the first side frame of the wire-fixing frame 1111, with its free end facing the second side frame; the second wire-fixing rib 1113 is connected to the second side frame of the wire-fixing frame 1111, with its free end facing the first side frame. The first and second side frames are side frames that are arranged opposite to each other in the wire-fixing frame 1111. In this embodiment, the first wire-fixing rib 1112 and the second wire-fixing rib 1113 are respectively arranged on both sides inside the wire-fixing frame 1111, and their free ends face opposite each other, which makes it easier to place and fix the line 20.

[0073] In this configuration, the first wire-fixing rib 1112 and the second wire-fixing rib 1113 are staggered in the direction from the top frame of the wire-fixing frame 1111 towards the bottom frame. That is, the first wire-fixing rib 1112 and the second wire-fixing rib 1113 are spaced apart in their stacking direction, providing sufficient space for the placement and removal of the wire 20, thus facilitating its installation and removal. For example, the first wire-fixing rib 1112 may be located below the second wire-fixing rib 1113, meaning the first wire-fixing rib 1112 is closer to the bottom frame.

[0074] The first wire-fixing rib 1112 is constructed as an elastic structure. In its free state, the first wire-fixing rib 1112 tilts towards the bottom frame of the wire-fixing frame 1111 from the side where the opening is located. Similarly, the second wire-fixing rib 1113 can also be constructed as an elastic structure, tilting towards the bottom frame of the wire-fixing frame 1111 from the side where the opening is located in its free state. In other words, after the wire 20 is fixed, both the first wire-fixing rib 1112 and the second wire-fixing rib 1113 tilt towards the location of the wire 20, thereby better securing the wire 20 and better preventing the wire 20 from detaching from the fixing frame. Furthermore, the elasticity of the first wire-fixing rib 1112 and the second wire-fixing rib 1113 facilitates the placement of the wire 20 and ensures that after the wire 20 is placed, the first wire-fixing rib 1112 and the second wire-fixing rib 1113 return to their free state, thus guaranteeing reliable fixation of the wire 20.

[0075] In the arrangement direction of the first side frame and the second side frame, the free end of the first wire fixing rib 1112 is closer to the second side frame than the free end of the second wire fixing rib 1113, and the free end of the second wire fixing rib 1113 is closer to the first side frame than the free end of the first wire fixing rib 1112. That is, the first wire fixing rib 1112 and the second wire fixing rib 1113 are arranged in an alternating manner, thereby improving the fixing effect on the line 20 and better preventing the line 20 from detaching freely from the wire fixing frame 1111.

[0076] The opening of the wire-fixing frame 1111 is located in its top frame, dividing the top frame into two parts. The part of the top frame connected to the first side frame is referred to as the first part, and the part of the top frame connected to the second side frame is referred to as the second part. The free end of the first part can be inclined towards the bottom frame of the wire-fixing frame 1111, and the free end of the second part can also be inclined towards the bottom frame of the wire-fixing frame 1111. Thus, the opening of the wire-fixing frame 1111 can be funnel-shaped, with the smaller side of the funnel-shaped opening facing the bottom frame and the larger side of the funnel-shaped opening facing away from the bottom frame. This facilitates the entry of the wire 20 into the wire-fixing frame 1111, improving the efficiency of wire fixing, and also better prevents the fixed wire 20 from freely detaching from the opening, thus improving the reliability of wire fixing.

[0077] The wire frame 1111, the first wire rib 1112, and the second wire rib 1113 can be integrally formed or they can be fixedly connected together by welding, bonding, or other methods. There is no limitation on this.

[0078] In this embodiment, after the wire 20 is inserted into the wire fixing frame 1111, it is adjusted and fixed by the elastic first wire fixing rib 1112 and the second wire fixing rib 1113. It should be noted that even without the ribs, the wire fixing frame 1111 itself has the effect of fixing the wire 20, and the ribs can better ensure that the wire 20 is not easily loosened after being inserted. The ribs are elastic structures, and the wire 20 can be better inserted after passing through the ribs. When the wire 20 is inserted, the rib near the bottom frame will spring up towards the gold bar near the top frame due to the force. The interaction between the two ribs can ensure that the wire 20 will not pop out, so as to ensure that the embedded wire 20 can be effectively fixed.

[0079] It should be noted that the wire fixing structure 11 in this disclosure can be in other forms besides those described above, and there is no limitation on this. For example, the wire fixing structure 11 can consist of a fixed base and an openable and closable buckle, which can be closed by elastic or magnetic means. After the wire 20 is embedded in the groove of the fixed base, the buckle presses the wire 20 tightly, and the wire 20 is fixed by the friction force generated by the elastic deformation. Anti-detachment hooks can also be provided on the buckle.

[0080] In one exemplary embodiment, a wire securing device and a screw assembly having the wire securing device provided are provided. (See reference...) Figures 1 to 5 As shown, in this embodiment, the screw connection device 2 may include a nut portion 22 and a stud portion 21. The stud portion 21 may be a screw or a bolt, and the nut portion 22 may be a conventional nut or an improved nut.

[0081] The mounting platform 12 can be an annular platform, with the stud portion 21 located in the hollow part of the annular platform to facilitate screwing the stud portion 21 and the nut portion 22. The bottom of the annular platform has a protrusion 122 extending towards the nut portion 22. The nut portion 22 can have a snap-fit ​​groove 221 that mates with the protrusion 122; that is, a conventional nut has a snap-fit ​​groove 221 to form an improved nut (i.e., the nut portion 22). The protrusion 122 snaps into the snap-fit ​​groove 221 to achieve a fixed connection between the annular platform and the nut portion 22. Alternatively, the nut portion 22 can be a conventional nut, with the bottom of the annular platform directly welded to the sidewall of the conventional nut, also achieving a fixed connection between the annular platform and the nut portion 22.

[0082] It should be noted that, in addition to being placed at the location of the bolted device 2 in the manner described above, the ring platform can also be placed at the location of the bolted device 2 in other ways, and there is no limitation on this.

[0083] The hollow portion of the annular platform is a cylindrical cavity 200. The radial dimension of the cylindrical cavity 200 is larger than the maximum radial dimension of the stud portion 21, for example, forming a radial gap of 0.5-2mm. This not only allows the stud portion 21 to be freely inserted into the cavity, but also enables quick initial screwing with the nut portion 22 without precise alignment, improving the ease of assembly between the stud portion 21 and the nut portion 22. It should be noted that the dimensions of the cylindrical cavity 200 can be adapted to the dimensions of the stud portion 21, and its specific dimensions are not limited.

[0084] In addition, after the stud part 21 and the nut part 22 are assembled, and after the wire fixing structure 11 and the mounting platform 12 are assembled, the bottom of the wire fixing structure 11 and the top of the stud part 21 are spaced apart in the axial direction of the screw connection device 2, for example, maintaining an axial gap of 5-10 mm, so as to avoid interference from the stud part 21 when the wire fixing structure 11 moves relative to the mounting platform 12.

[0085] The snap-fit ​​groove 221 is an annular groove that extends circumferentially along the nut portion 22. The protrusion 122 is an annular protrusion that snaps into the annular groove. The engagement of the annular protrusion and the annular groove increases the connection area between the annular platform and the nut portion 22, thereby improving the reliability of their fixed connection. It should be noted that after the two parts are snapped together by the annular protrusion and the annular groove, welding or bonding can be used at the snap-fit ​​location to further enhance the reliability of the fixed connection.

[0086] In this embodiment, the annular platform and nut portion 22 can be assembled first, then the assembled components can be placed in the required position, and then the stud portion 21 can be installed so that the stud portion 21 and nut portion 22 are screwed together and fixed. Finally, the wire fixing structure 11 can be installed onto the annular platform. Of course, since the wire fixing structure 11 can be rotated along the annular platform to adjust its position, the wire fixing structure 11 can also be installed first, and then the stud portion 21 can be installed. If it is convenient to assemble the annular platform and nut portion 22, the wire fixing structure 11 can also be installed onto the annular platform first, and then the annular platform and nut portion 22 can be assembled. There is no limitation on this.

[0087] In this embodiment, a certain gap is reserved between the hollow cylindrical cavity 200 of the annular platform and the stud portion 21, so that the stud portion 21 can be quickly inserted into the nut portion 22 without precise alignment, improving assembly efficiency. Simultaneously, the annular platform and the nut portion 22 can be pre-assembled to form a modular component. During installation, the component is directly fitted onto the stud and tightened, reducing step-by-step operations and further improving assembly line efficiency. Furthermore, when an annular protrusion is used, the 360° full-circumferential engagement between the annular protrusion and the annular groove significantly improves the reliability of the engagement compared to traditional single-point connections. After engagement, a composite fixing method of welding or bonding provides dual protection of mechanical locking and chemical bonding, better ensuring the stability and reliability of the wiring device 1 in complex environments. Moreover, the movable connection design between the wiring structure 11 and the annular platform allows for 360° free rotation. Combined with the axial gap between the top of the wiring structure 11 and the stud portion 21, this completely eliminates wiring interference, allowing the line 20 to flexibly turn in confined spaces, improving wiring efficiency. Furthermore, the dimensions of the hollow cylindrical cavity 200 in this embodiment can be flexibly adjusted according to different specifications of the stud portion 21. The snap-fit ​​structure between the annular platform and the nut is compatible with conventional nut modifications and customized nut designs, thus expanding its applicability. At the same time, the diverse installation sequence options (installing the fixing structure 11 first or the stud first) can be flexibly adjusted according to the actual production process, improving the product's production adaptability.

[0088] That is, this embodiment, through the ring-shaped snap-fit ​​structure and hollow platform design, can greatly improve assembly efficiency, connection reliability, and space utilization, and better solve the problems of difficult wiring and easy loosening in traditional screw-fit areas.

[0089] It should be noted that the wire fixing device disclosed herein can be applied not only to the location of the screw connection device 2, but also to other wiring locations to improve the convenience of wiring. For example, in other locations with sharp edges or burrs, this wire fixing device can also be installed to fix the line 20, which can protect the line 20 from damage caused by friction, avoid increasing the diameter of the line 20, reduce the length and cost of the line 20, and facilitate the adjustment of the wiring direction, making wiring easier and improving the convenience of wiring.

[0090] Furthermore, the mounting platform 12 can be any shape other than a ring platform; there is no limitation in this regard. Correspondingly, the movement path of the fixed structure 11 relative to the mounting platform 12 can be any path other than a 360° omnidirectional rotation, such as an arc path or a straight path, etc.; there is no limitation in this regard.

[0091] For example, the mounting platform 12 can be a sector-shaped platform with a central angle of 120°, and a through hole at the center for mounting screws or bolts. The upper edge of the sector-shaped platform has an arc-shaped groove 100, and the radius of curvature of the groove 100 can be consistent with the outer circle of the sector. This mounting platform 12 can be used for arc-shaped wiring in circular electrical boxes (such as frequency converter module boxes). By adjusting the angle of the wire fixing structure 11 relative to the mounting platform 12, the wires 20 can be arranged in an orderly manner along the edge of the box, avoiding interference with the cooling fan.

[0092] In one exemplary embodiment, an electrical device is provided. This electrical device can be a small electrical component such as an electrical box or meter box, or a large integrated device such as an air conditioner or television set; there is no limitation in this regard.

[0093] Among them, reference Figures 1 to 5 As shown, the electrical device includes the aforementioned screw assembly 10. The screwing device 2 in the screw assembly 10 can be used to fix various structural components such as sheet metal parts 40, circuit boards 30, or injection molded parts in the electrical device. By setting the aforementioned screw assembly 10, the electrical device can improve the safety of the wiring 20 and also improve the convenience of wiring.

[0094] In some implementations...

[0095] refer to Figures 1 to 5 As shown, the electrical device can be an electrical box, and the screw assembly 10 can include screws, nuts, a mounting platform 12, and a wire fixing structure 11. The mounting platform 12 is constructed as a ring platform, with a circular recessed area in the center forming a cylindrical cavity 200 for screw insertion and fixing. The wire fixing structure 11 is located at the top edge of the mounting platform 12 (in this embodiment, the side of the mounting platform 12 away from the screw is called the upper edge), and the edge of the mounting platform 12 has a groove 100 to accommodate the wire fixing structure 11.

[0096] The wire fixing structure 11 may include a wire fixing frame 1111 and a rib assembly located within the wire fixing frame 1111. The rib assembly includes a first wire fixing rib 1112 and a second wire fixing rib 1113, which are respectively connected to the two side frames of the wire fixing frame 1111. The first wire fixing rib 1112 and the second wire fixing rib 1113 are staggered in the direction from the top frame of the wire fixing frame 1111 towards the bottom frame of the wire fixing frame 1111. That is, the first wire fixing rib 1112 and the second wire fixing rib 1113 are spaced apart in their stacking direction by a certain distance, providing sufficient space for the placement and removal of the wire 20, thereby facilitating the placement and removal of the wire 20.

[0097] The opening of the wire-fixing frame 1111 is located in its top frame, dividing the top frame into two parts. The part of the top frame connected to the first side frame is referred to as the first part, and the part of the top frame connected to the second side frame is referred to as the second part. The free end of the first part can be inclined towards the bottom frame of the wire-fixing frame 1111, and the free end of the second part can also be inclined towards the bottom frame of the wire-fixing frame 1111. Thus, the opening of the wire-fixing frame 1111 can be funnel-shaped, with the smaller side of the funnel-shaped opening facing the bottom frame and the larger side of the funnel-shaped opening facing away from the bottom frame. This facilitates the entry of the wire 20 into the wire-fixing frame 1111, improving the efficiency of wire fixing, and also better prevents the fixed wire 20 from freely detaching from the opening, thus improving the reliability of wire fixing.

[0098] The reinforcing ribs can be elastic. In their free state, the first reinforcing rib 1112 tilts towards the bottom frame of the wire-fixing frame 1111 from the side where the opening is located, and the second reinforcing rib 1113 tilts towards the bottom frame of the wire-fixing frame 1111 from the side where the opening is located. That is, after the wire 20 is fixed, both the first reinforcing rib 1112 and the second reinforcing rib 1113 tilt towards the position of the wire 20, thereby better fixing the wire 20 and better preventing the wire 20 from coming out of the fixing frame. In addition, the elastic first reinforcing rib 1112 and the second reinforcing rib 1113 not only facilitate the placement of the wire 20, but also ensure that the first reinforcing rib 1112 and the second reinforcing rib 1113 return to their free state after the wire 20 is placed, thereby ensuring the reliable fixation of the wire 20.

[0099] In this embodiment, after the wire 20 is inserted into the wire fixing frame 1111, it is adjusted by the rib assembly. Since the ribs can be elastic structures, when the wire 20 is inserted, the lower rib will spring upward due to the force, interacting with the upper rib to ensure that the wire 20 will not pop out, thus ensuring that the wire 20 is effectively fixed after being embedded. It should be noted that a silicone buffer layer can be covered on the wire fixing frame 1111 and the ribs to better protect the wire 20.

[0100] The wire-fixing structure 11 may further include a sphere located at the bottom of the wire-fixing frame 1111. A circular inlet 300 is also provided on the mounting platform 12. The sphere at the bottom of the wire-fixing frame 1111 can be inserted into the groove 100 through the inlet 300 and can slide along the groove 100. The engagement of the sphere with the groove 100 can prevent the sphere from dislodging from the groove 100 during sliding relative to it, ensuring the reliability of the movable connection between the two.

[0101] In this embodiment, the cross-section of the groove 100 is adapted to the sphere, and the size of its groove opening is smaller than the diameter of the sphere. Based on this, the sphere can slide stably within the groove 100 without falling off. In this embodiment, the wire fixing device 1 can realize the movement of the wire fixing structure 11 relative to the mounting platform 12 through the cooperation of the sphere and the groove 100, thereby realizing the adjustment of the wire routing direction.

[0102] The slide groove 100 can be disposed on an annular platform and extends circumferentially along the annular platform to form an annular slide groove 100. The ball of the wire fixing structure 11 can slide along the annular slide groove 100, thereby realizing a 360° rotation of the wire fixing structure 11 relative to the mounting platform 12, and thus realizing a 360° adjustment of the wiring direction. This embodiment, through the movable connection between the ball and the slide groove 100, can greatly improve the wiring flexibility, structural reliability, and installation convenience, effectively solving the problems of difficult wiring and high cost in the area of ​​traditional screw-in devices 2.

[0103] The fixed wire frame 1111 can be made by means of mold processing, etc., and is built in the groove 100 at the edge of the mounting platform 12 to meet the requirements of various wiring methods and wire diameters.

[0104] In this embodiment, an annular groove is provided in the middle of the side wall of the nut, which is recessed toward the center of the nut. An annular protrusion is provided at the bottom of the mounting platform 12, which protrudes toward the nut. The mounting platform 12 is fixed by the annular nesting between the annular protrusion and the annular groove. After the screws are installed, the wire fixing structure 11 can rotate 360° in all directions to adapt to the fixing of the line 20 in all directions.

[0105] It should be noted that when the screw device is used on, for example, sheet metal parts 40, PCB boards, or loads, the wire routing 20 passes through the wire fixing structure 11 on the screw device for wire fixation. After the wire 20 passes through the wire fixing structure 11, combined with the height of the mounting platform 12, the height of the wire from the screw head can effectively avoid the position of the screw head, thereby avoiding the potential hazards of routing above the screw.

[0106] In this embodiment, if the line 20 needs to avoid the sharp edges on the sheet metal parts 40 inside the electrical box or various electronic components on the motherboard, the wire fixing structure 11 can adjust the routing direction by sliding along the slide groove 100 to solve the wiring safety hazards inside the electrical box and increase the safety and reliability of the wiring inside the electrical box.

[0107] It should be noted that in this embodiment, the method of fixing the line 20 is not limited to the cooperation of the fixing frame 1111 and the rib assembly. Other fixing structures 11 can also be adapted to the mounting platform 12 to meet the actual use needs of various wiring and realize the diversity of wiring methods.

[0108] In this embodiment, the fixing position of the fixing structure 11 and the screw connection device 2 are axially spaced apart. The wire 20 is fixed on the fixing structure 11, and a safe distance is maintained between it and the burrs on the top of the screw connection device 2, avoiding damage to the insulation layer of the wire 20 due to long-term friction. This significantly improves the safety and reliability of the wire 20. Moreover, there is no need to increase the length and cost of the wire 20 by routing the wire around the screw connection device 2. In other words, this embodiment can reduce the length and cost of the wire 20. In addition, this embodiment can adjust the routing direction by moving the fixing structure 11 on the mounting platform 12, thereby better optimizing the path of the wire 20, making the layout of the wire 20 easier, and further shortening the diameter of the wire 20, further reducing the wiring length, and reducing the cost of wire materials and installation time.

[0109] In addition, since the routing direction can be adjusted, if the layout of the line 20 needs to be changed during equipment maintenance, the line 20 can be adjusted by moving the fixed structure 11 relative to the mounting platform 12, which makes maintenance easier.

[0110] Moreover, this embodiment, through the movable connection between the ball and the slide 100, can greatly improve the flexibility of wiring, structural reliability, and ease of installation, effectively solving the problems of difficult wiring and high cost in the area of ​​traditional screw-connected devices 2.

[0111] In addition, in this embodiment, after the wire 20 is inserted into the wire fixing frame 1111, it is adjusted and fixed by the elastic first wire fixing rib 1112 and the second wire fixing rib 1113. It should be noted that even without the ribs, the wire fixing frame 1111 itself has the effect of fixing the wire 20, and the ribs can better ensure that the wire 20 is not easy to loosen after it is inserted. The ribs are elastic structures, and the wire 20 can be better inserted after passing through the ribs. When the wire 20 is inserted, the rib near the bottom frame will spring up towards the gold bar near the top frame due to the force. The interaction between the two ribs can ensure that the wire 20 will not pop out, so as to ensure that the embedded wire 20 can be effectively fixed.

[0112] Moreover, this embodiment, through its ring-shaped snap-fit ​​structure and hollow platform design, can significantly improve assembly efficiency, connection reliability, and space utilization, and better solve the problems of difficult wiring and easy loosening in traditional screw-fit areas.

[0113] In this embodiment, a wire fixing device 1 is built on the screw connection device 2 in different situations such as fixing sheet metal parts 40, circuit boards 30 and injection molded parts. This can effectively reduce the safety hazards of wire routing and save the wiring space in the area, thereby increasing the reliability of wiring in electrical equipment such as electrical boxes.
