[0028] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] like Figures 1 to 5 As shown, the wire buckle assembly of Embodiment 1 includes: a fixing member 10, a wire buckle 20, and a limiting structure 30. The wire buckle 20 includes a mounting portion 21 sleeved on the fixing member 10 and a threading portion 22 with a threading hole 221. The wire buckle 20 is rotatable relative to the fixing member 10. The limiting structure 30 is disposed between the fixing member 10 and the mounting portion 21 to restrict the wire buckle 20 from moving axially along the fixing member 10.

[0033] Applying the technical solution of Embodiment 1, before fixing the cable, the fixing member 10 is first fixed to the junction box panel, and then the wire clip 20 is sleeved on the fixing member 10. Due to the presence of the limiting structure 30, the axial direction of the wire clip 20 sleeved on the fixing member 10 is limited, but it has freedom in the circumferential direction. After the wire clip assembly is installed, the position of the wire clip 20 is adjusted to a position relatively far away from the junction box panel. At this time, the cable can be smoothly passed through the wire hole 221 to fix the cable within a certain range. Therefore, the above structure allows the position of the wire clip 20 to be adjusted regardless of the cable's direction, so that the cable is aligned with the wire hole 221, preventing cable damage. Applying the technical solution of Embodiment 1 can improve the flexibility of wire pulling and ensure the service life of the cable.

[0034] like Figures 1 to 3 and Figure 5 As shown in Embodiment 1, the mounting part 21 is provided with a mounting hole 211 for the fastener 10 to pass through. The limiting structure 30 includes a snap-fit ​​protrusion 31 and a limiting groove 32 that engage with each other. The snap-fit ​​protrusion 31 is disposed on the wall of the mounting hole 211, and the limiting groove 32 is disposed on the outer wall of the fastener 10. When the snap-fit ​​protrusion 31 is opposite to the limiting groove 32, part of the snap-fit ​​protrusion 31 extends into the limiting groove 32. The two opposing groove walls of the limiting groove 32 can limit the displacement of the mounting part 21 in the axial direction of the fastener 10, ensuring that the buckle 20 does not come off the fastener 10. The above structure is simple and easy to manufacture. Of course, in other embodiments not shown in the figure, the snap-fit ​​protrusion 31 can be disposed on the outer wall of the fastener 10, and the limiting groove 32 can be disposed on the wall of the mounting hole 211.

[0035] In Embodiment 1, the snap-fit ​​protrusion 31 is elastic. This structure allows the snap-fit ​​protrusion 31 to retract under the pressure of the outer wall of the fastener 10 when the buckle 20 is fitted onto the fastener 10. When the buckle 20 moves to a position where the snap-fit ​​protrusion 31 aligns with the limiting groove 32, the snap-fit ​​protrusion 31 can extend into the limiting groove 32 under the action of elastic restoring force, thus achieving a snap-fit ​​engagement. This structure is simple and easy to install. Of course, in other embodiments not shown in the figures, the snap-fit ​​protrusion 31 may not be elastic. For example, the snap-fit ​​protrusion may be movably mounted on the buckle, allowing it to move when it aligns with the limiting groove 32, so that a portion of the snap-fit ​​protrusion moves into the limiting groove.

[0036] In Embodiment 1, the snap-fit ​​protrusion 31 and the wire buckle 20 are integrally formed. The above structure is simple, easy to manufacture, has high production efficiency, and is easy to install.

[0037] In Example 1, the wire buckle assembly is made of plastic. The above structure is simple and has low production cost.

[0038] like Figure 4 As shown, in Embodiment 1, the fastener 10 is a rivet, which includes a main body 11 and a cap 12. The limiting groove 32 is an annular groove provided on the main body 11. The above structure does not restrict the rotation angle of the wire buckle 20 relative to the fastener 10, making the wire buckle assembly more flexible.

[0039] like Figures 1 to 3 and Figure 5 As shown, in Embodiment 1, the snap-fit ​​protrusions 31 are arranged in multiple spaced intervals along the circumferential direction of the mounting hole 211. The portion of the snap-fit ​​protrusion 31 furthest from the cap 12 has a deformation groove 312 between it and the mounting hole 211. The inner surface of the snap-fit ​​protrusion 31 is a guide slope 313 that gradually tapers inward from the cap 12 to the main body 11. This structure makes the snap-fit ​​protrusion 31 more easily deformable, making it easier for the buckle 20 to be fitted onto the fastener 10, and allowing the snap-fit ​​protrusion 31 to engage deeper into the deformation groove 312, ensuring a limiting effect.

[0040] like Figures 1 to 3 and Figure 5 As shown in Embodiment 1, the mounting hole 211 is further provided with a plurality of guide posts 40 extending along the axial direction of the mounting hole 211 on the hole wall. The guide posts 40 are alternately arranged with the snap-fit ​​protrusions 31. The guide posts 40 can guide the cable clip 20 when it is sleeved on the fixing member 10. It should be noted that the guide posts 40 can have a slight interference fit with the outer surface of the fixing member 10, so that the cable clip 20 can only rotate when the user rotates it, that is, the cable clip 20 will not easily rotate when it is not subjected to external force, further enhancing the fixing effect of the cable.

[0041] like Figures 1 to 5 As shown, in Embodiment 1, the threading portion 22 is angled and positioned on one side of the mounting portion 21. This structure ensures that the length and width of the wire clip assembly are unaffected, allowing the fastener 10 to be positioned closer to the box panel, reducing requirements on the installation position of the fastener 10 and increasing flexibility. Preferably, in this embodiment, the threading portion 22 and the mounting portion 21 are perpendicular to each other.

[0042] like Figure 6 and Figure 7 As shown, the difference between the wire buckle assembly of Embodiment 2 and the wire buckle assembly of Embodiment 1 lies only in the positional relationship between the threading part 22 and the mounting part 21. Specifically, in Embodiment 2, the threading part 22 is horizontally disposed on one side of the mounting part 21. The above structure is simple and easy to manufacture.

[0043] This application also provides a junction box, which, according to an embodiment of the junction box (not shown in the figure), includes a box body and a wire clip assembly. The wire clip assembly is disposed on the box body and is the wire clip assembly described above. Since the wire clip assembly described above has the advantages of improving cable threading flexibility and protecting cables, the junction box having it also has the aforementioned advantages.

[0044] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0045] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0046] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
