[0041] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0042] Traditional wiring requires winding wires around screws, resulting in low wiring efficiency and the tendency for unsightly, messy, and unreliable "flying wires" to appear in the field. These flying wires also reduce clearance and creepage distance, posing safety hazards such as short circuits and sparks. To address these issues, this invention proposes a wiring screw structure and wiring device that eliminates flying wires, ensures safe and reliable on-site wiring, and simultaneously improves wiring efficiency.

[0043] Please refer to the following: Figure 1 The wiring screw structure 1 in the preferred embodiment of this utility model includes at least:

[0044] Screw body 10;

[0045] The cable hub 11 is used to insert the wire 5, and the cable hub 11 is sleeved on the screw body 10;

[0046] The wire clamping component 12 is used to clamp the wire assembly 11. The wire clamping component 12 includes two wire clamping washers 121, which are sleeved on the screw body 10 and located on both sides of the wire assembly 11.

[0047] Thus, this invention eliminates the need to remove screws, allowing direct insertion of the wire 5 into the hub component 11. This efficient insertion process significantly improves wiring efficiency. Furthermore, the hub component 11 collects the wire 5, eliminating loose wires and resulting in neater, more aesthetically pleasing wiring, thus enhancing on-site wiring safety. Moreover, the clamping component 12 secures the hub component 11 between the two clamping pads 121, ensuring reliable clamping and preventing the hub component 11 from loosening under pressure, thereby guaranteeing safe and reliable on-site wiring. This invention significantly improves wiring efficiency, safety, and reliability.

[0048] like Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment of this utility model, the hub component 11 includes:

[0049] The cable collection ring 112 has a cable collection cavity inside, and the two ends of the cable collection cavity are the cable inlet 114 and the cable stop 115;

[0050] The traction slider 113 has an open hollow structure inside for inserting the power supply line 5. The traction slider 113 is slidably placed in the cable collection cavity to carry the power line 5 from the inlet 114 to the stop 115.

[0051] Thus, this utility model can use the traction slider 113 to carry the wire 5 from the inlet 114 of the wire collection ring 112 to the stop 115, which can quickly guide the wire 5 into the wire collection cavity and ensure a certain insertion depth. This avoids the cumbersome operation of traditional winding wiring, and realizes the wire 5 being gathered in the wire collection component 11, avoiding the wire core being exposed or scattered, eliminating flying wires, and reducing electrical safety hazards such as short circuits. In addition, the wire collection ring 112 itself is a ring with a notch, which can shape the wire 5 into a ring, thereby ensuring that the wire 5 will not deform or loosen when subjected to external force. At the same time, under the action of the wire collection ring 112, the wire 5 will not generate flying wires.

[0052] It should be noted that the diameters of the inlet 114 and the stop 115 of the cable ring 112 can be different. To facilitate the insertion of the wire 5, the inlet 114 can be set to have a larger diameter, and to prevent the wire 5 from coming loose, the stop 115 can be set to have a smaller diameter. The specific diameters of the inlet 114 and the stop 115 can be set according to the actual application requirements.

[0053] It should also be noted that the cable collector ring 112 can be compressed and deformed so that it can be pressed tightly by the upper and lower pressure pads 121. The cable collector ring 112 itself can be a ring with a notch, and the length of the notch can be set according to actual needs. The traction slider 113 itself can be shaped like a straw hat, thin and deformable.

[0054] like Figure 6 , Figure 7 As shown, in a preferred embodiment of this utility model, a first anti-detachment block 116 is provided on the cavity wall of the cable collection cavity near the cable inlet 114. The first anti-detachment block 116 restricts the open end of the traction slider 113 from being exposed from the cable inlet 114.

[0055] Thus, this utility model provides a first anti-detachment block 116 inside the cable collection cavity. The first anti-detachment block 116 can interlock with the open end of the slider to ensure that the traction slider 113 will not come out of the cable inlet 114 after it has fully entered the cable collection ring 112, thereby improving reliability.

[0056] It should be noted that the shape of the first anti-detachment block 116 can be set according to actual needs. Preferably, the cross-sectional shape of the first anti-detachment block 116 is an inverted triangle. In actual application, the tail of the traction slider 113 retracts into the cable collector ring 112. After it is fully inside the cable collector ring 112, the tail of the traction slider 113 rebounds. At this time, under the action of the first anti-detachment block 116, the traction slider 113 will not detach from the cable collector ring 112 from the side of the cable inlet 114.

[0057] like Figure 4 As shown, in a preferred embodiment of this utility model, a slider retaining ring 117 is sleeved on the outside of the traction slider 113.

[0058] Thus, this invention utilizes a slider retaining ring 117 fitted around the traction slider 113. The slider retaining ring 117 engages with the inner wall of the cable collection cavity, providing clear guidance for the movement of the traction slider 113. This allows the traction slider 113 to move smoothly along the cable collection cavity from the inlet 114 to the stop 115, ensuring the accuracy of the movement direction. This helps prevent the traction slider 113 from deviating or jamming during movement, ensuring that the wire 5 can be accurately guided to the stop 115 position of the cable collection ring 112, achieving precise positioning. Simultaneously, the slider retaining ring 117 generates friction with the inner wall of the cable collection cavity, temporarily fixing the position of the traction slider 113. Even under vibration or incomplete compression, it prevents the traction slider 113 from accidentally sliding or loosening.

[0059] It should be noted that the slider retaining ring 117 can have a small notch in the middle, allowing it to be pried open and secured to the traction slider 113. The slider retaining ring 117 can also divide the traction slider 113 into a head and a tail. The slider retaining ring 117 is fixed to the traction slider 113 near the open end, in which case the head of the traction slider 113 is slightly longer than the tail.

[0060] like Figure 8 , Figure 9 As shown, in a preferred embodiment of this utility model, a second anti-detachment block 118 is provided on the cavity wall of the cable collection cavity near the stop opening 115, and the second anti-detachment block 118 restricts the slider retaining ring 117 from being exposed from the stop opening 115.

[0061] Thus, this utility model provides a second anti-detachment block 118 in the cable collection cavity. The second anti-detachment block 118 can interlock with the slider retaining ring 117 to ensure that the traction slider 113 will not come out of the stop opening 115 after it has fully entered the cable collection ring 112, thereby improving reliability.

[0062] It should be noted that the shape of the second anti-detachment block 118 can be set according to actual needs. Preferably, the cross-sectional shape of the second anti-detachment block 118 is an inverted triangle. In practical applications, after the wire 5 is inserted into the traction slider 113, under the action of the traction slider 113, when the front end of the wire 5 moves to the stop opening 115 of the wire collecting ring 112, the head of the traction slider 113 protrudes from the stop opening 115 of the wire collecting ring 112, indicating that the wire 5 has been fully inserted into the wire collecting ring 112. At the same time, under the action of the second anti-detachment block 118, the traction slider 113 will not detach from the wire collecting ring 112 from the stop opening 115 side.

[0063] In a preferred embodiment of this utility model, the cable ring 112 and the traction slider 113 are made of copper.

[0064] Thus, this utility model uses copper for both the coil ring 112 and the traction slider 113. Copper is an excellent conductor of electricity, ensuring efficient current transmission between the coil ring 112, the traction slider 113, and the wire 5, reducing energy loss and heat generation, and improving the stability and safety of the electrical connection. At the same time, copper is highly ductile and easily processed into the hat-shaped thin-walled structure of the traction slider 113. This allows the traction slider 113 to contract and deform when inserted into the coil cavity from the inlet 114 side of the coil ring 112, and to spring back after fully entering the coil cavity. The coil ring 112 can also be compressed and deformed. Furthermore, the coil ring 112 can withstand the clamping force of the pressure pad 121 while avoiding damage to the wire 5, achieving the dual effect of reliable crimping and protection of the wire 5.

[0065] like Figure 1 As shown, in a preferred embodiment of this utility model, the wire pressing pad 121 is provided with anti-detachment wire pressing teeth 122 on the side facing the wire gathering component 11.

[0066] Thus, by providing anti-detachment pressure teeth 122 on the pressure pad 121, the present invention can quickly lock the cable hub 11 and increase the pressure force applied by the pressure pad 121 to the cable hub 11. Even if the cable hub 11 is subjected to external forces such as vibration and pulling, it can effectively prevent loosening and ensure the long-term stability of the electrical connection.

[0067] It should be noted that the number of anti-detachment crimping teeth 122 on the crimping pad 121 can be set according to actual needs and is not limited here. Usually, the anti-detachment crimping teeth 122 on the two crimping pads 121 are symmetrically arranged. The anti-detachment crimping teeth 122 can also be deformed to adjust the engagement depth, so as to better crimp the wire assembly 11 and adapt to wire assemblies 11 of different thicknesses.

[0068] It should also be noted that the wire clamping pad 121 is curved or deformable. When the edges of the two wire clamping pads 121 abut each other, it can be determined that the wire assembly 11 has been clamped, thereby more reliably flattening and clamping the wires 5 inside the wire assembly 11.

[0069] like Figure 1 As shown, in a preferred embodiment of this utility model, the wiring screw structure 1 further includes an anti-loosening washer 13, which is sleeved on the screw body 10 and abuts against the head of the screw body 10 and one of the wire pressing washers 121.

[0070] Therefore, this utility model also provides an anti-loosening washer 13 for the wiring screw structure 1. The anti-loosening washer 13, by increasing friction or mechanical locking (such as the elastic tension of a spring washer), can effectively prevent the screw from loosening due to vibration, temperature changes, or external force, thereby preventing the pressure drop of the wire clamping washer 121 due to screw loosening, ensuring that the wire clamping washer 121 continuously presses against the wiring assembly 11, and maintaining the stability of the electrical connection. At the same time, the anti-loosening washer 13, as a buffer layer between the screw head and the wire clamping washer 121, can distribute the concentrated pressure when the screw is tightened to a larger area, preventing the wire clamping washer 121 from deforming or being damaged due to excessive local force, and extending its service life.

[0071] like Figure 1 As shown, in a preferred embodiment of this utility model, the anti-detachment pad 13 is provided with a locking tooth 131, and the wire pressing pad 121 is provided with a locking groove 123 that engages with the locking tooth 131.

[0072] Thus, this utility model also uses the locking teeth 131 on the anti-detachment pad 13 to engage with the locking groove 123 on the wire pressing pad 121, so that the anti-detachment pad 13 and the wire pressing pad 121 are locked more tightly, making the wire pressing pad 121 less likely to loosen, thereby ensuring that the wire pressing pad 121 continuously presses the wire assembly 11.

[0073] It should be noted that the anti-loosening washer 13 may also be provided with retaining teeth 131 that abut against the screw head, which can increase the connection force between the screw head, the wire clamping washer 121 and the anti-loosening washer 13, and further prevent loosening. In addition, one side of the wire clamping washer 121 is provided with a groove 123, and the other side of the wire clamping washer 121 is provided with a protrusion opposite to the groove 123, thereby increasing local strength to prevent breakage, and the two wire clamping washers 121 can be quickly and accurately positioned according to the position of the protrusions of the two wire clamping washers 121.

[0074] like Figure 10 , Figure 11As shown, the wiring device in the preferred embodiment of this utility model includes a base 2, a conductive plate 3, a fixing nut 4, and a wiring screw. The base 2 has a mounting hole. The wiring screw passes through the conductive plate 3 and is inserted into the mounting hole. The fixing nut 4 is located in the mounting hole and is sleeved on the wiring screw. The number of wiring screws can be, but is not limited to, three. Each wiring screw adopts the wiring screw structure 1 described above, which will not be repeated here.

[0075] Thus, this invention improves the efficiency of on-site wiring. Conventional on-site wiring requires removing the wiring screw from the base 2 of the wiring device and then winding the wire 5 around the screw. This process of removing the screw and winding the wire is time-consuming and laborious, and there is a risk of the screw falling out or being lost. This invention eliminates the need to remove the screw, allowing the wire 5 to be directly inserted into the hub component 11. The insertion process is highly efficient, and after insertion, the screw can be tightened directly, effectively improving wiring efficiency. Furthermore, the hub component 11 collects the wires 5, eliminating loose wires and making the wiring neat and aesthetically pleasing, thus improving on-site wiring safety. Moreover, the wire clamping component 12 presses the hub component 11 firmly between the two clamping washers 121, ensuring reliable clamping and preventing the hub component 11 from loosening under pressure, thus guaranteeing safe and reliable on-site wiring. This invention significantly improves wiring efficiency, safety, and reliability.

[0076] This invention also achieves the effect of standardizing on-site wiring. The standard wiring device eliminates quality differences caused by operational variations and ensures the consistency of on-site wiring.

[0077] like Figure 12 As shown, when using the wiring device described above for wiring, the wiring method includes the following steps:

[0078] S1. Insert the wire into the hub assembly;

[0079] S2. Rotate the screw body until the two wire clamping washers press the hub component firmly.

[0080] Thus, this invention eliminates the need to remove screws, allowing wires to be directly inserted into the hub component. The insertion process is highly efficient, and after insertion, the screws can be tightened directly, effectively improving wiring efficiency. Furthermore, the hub component collects the wires, eliminating loose wires and resulting in neat and aesthetically pleasing wiring, thus enhancing on-site wiring safety. Moreover, the clamping component presses the hub component firmly between the two clamping pads, ensuring reliable crimping and preventing the hub component from loosening under pressure, guaranteeing safe and reliable on-site wiring. This invention significantly improves wiring efficiency, safety, and reliability.

[0081] like Figure 13 As shown, the insertion of the wire into the hub is achieved in the following way:

[0082] S11. Insert the wire into the traction slider through the inlet of the hub ring;

[0083] S12. Push the traction slider to move within the cable collection cavity of the cable collector ring until a portion of the traction slider protrudes from the stop opening of the cable collector ring.

[0084] Thus, this utility model can use a traction slider to carry the wire from the inlet of the wire gathering ring to the stop, which can quickly guide the wire into the wire gathering cavity and ensure a certain insertion depth. This avoids the cumbersome operation of traditional winding wiring, and realizes the wire being bundled in the wire gathering component, avoiding exposed or scattered wire cores, eliminating flying wires, and reducing electrical safety hazards such as short circuits.

[0085] It should be understood that, in the description of this utility model, unless otherwise expressly specified and limited, when an element is referred to as "fixed to" or "set on" another element, it may be directly on or indirectly on the other element. When an element is referred to as "connected to" another element, it may be directly connected to or indirectly connected to the other element.

[0086] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0087] Furthermore, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0088] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
