Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a cable box for storing connecting cables. Background Technology

[0002] There are many types of cables on the market, which can be classified by function as power cables, data cables, audio cables, etc. To facilitate the storage of cables, cable boxes are generally used to store them, with the cables wound inside the box when stored.

[0003] See patent document CN2023104142852, which discloses a power socket. The power socket includes a rotating conductive device, a socket panel, a socket housing connected to the socket panel, and a circuit assembly disposed within the socket housing. The rotating conductive device is electrically connected to the circuit assembly and includes a conductive component, an elastic device, a locking device, and a wire. The conductive component includes a conductive shaft, a conductive carrier, and a conductive base. Current first flows through the conductive base, then the conductive base flows through the conductive shaft, and the conductive shaft then transmits current to the conductive carrier. The conductive carrier can rotate around the conductive shaft. The wire is electrically connected to the conductive carrier. The wire is wound up by rotating around the conductive shaft through the conductive carrier. The conductive carrier can stably input and output current to the wire. The elastic device is responsible for rewinding the wire, and the locking device is responsible for limiting the length of the wire pulled out.

[0004] The power socket's cable is wound and stored within the socket housing. Specifically, one end of the cable is free, while the other end is electrically fixed to a conductive carrier. Since the cable needs to be wound and stored, a conductive shaft is used as the central axis, and the conductive carrier rotates relative to the conductive shaft to achieve the winding and storage of the cable. Therefore, the conductive shaft needs to be fixed relative to the housing. Referring to the patent document, to achieve this fixation, a rectangular locking block is typically formed at the end of the conductive shaft, and a square hole is opened on the end face of the housing. During assembly, the rectangular locking block of the conductive shaft is inserted into the square hole, and the conductive shaft is fixed relative to the housing through an interference fit. However, this method of fixing the conductive shaft has a problem of instability. The fit between the rectangular locking block and the square hole only restricts the horizontal degree of freedom, not the vertical degree of freedom. In practical applications, the conductive shaft will move vertically relative to the housing, which will affect the working performance of the connecting cable and result in structural instability. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a wire box for storing connecting wires, which solves the problem of unstable structure in the past by improving the connection structure between the conductive shaft and the housing.

[0006] To solve the above-mentioned technical problems, this utility model discloses a cable box for storing connecting wires, including a housing and a conductive shaft. The bottom end of the conductive shaft extends downward to form a pair of elastic arms that are spaced apart. The bottom end of each elastic arm extends downward to form a plug-in part. The outer side of each plug-in part is provided with a slot. The bottom surface of the housing is provided with a pair of slotted holes that are spaced apart. The inner side of each slot is provided with a retaining part extending toward the slot. In the assembled state, the plug-in part is inserted into the slot, the retaining part is inserted into the slot, and the bottom surface of the elastic arm abuts against the inner bottom surface of the housing.

[0007] The upper part of the inner side of the card hole has a first guide slope that slopes upward.

[0008] The lower part of the outer side of the elastic arm has a second guide slope that slopes downward.

[0009] The shape of the card hole can be one of the following: fan-shaped, circular, rectangular, triangular, or polygonal.

[0010] The cross-sectional shape of the connector is one of the following: fan-shaped, circular, rectangular, triangular, or polygonal.

[0011] The device also includes a connecting wire body, a conductive carrier, and a wire clamp located inside the housing. The conductive carrier is sleeved on the outer periphery of the conductive shaft and electrically connected to the conductive shaft. The conductive carrier can rotate relative to the housing around the conductive shaft. The wire clamp has a wire routing hole and is fixedly connected to the conductive carrier. One end of the connecting wire body is a free end that extends out of the housing, and the other end of the connecting wire body passes through the wire routing hole of the wire clamp and is electrically connected to the conductive carrier.

[0012] It also includes a rotating disk located inside the housing and rotatable relative to the housing, the rotating disk being fixedly connected to the conductive carrier.

[0013] It also includes a torsion spring located inside the housing and used to drive the rotating disk to rotate.

[0014] It also includes a limiting component located inside the housing to restrict the rotation of the rotating disk.

[0015] The housing includes a bottom shell and a PCB panel that is detachably connected to the bottom shell.

[0016] Compared with the prior art, the present invention has the following advantages: by setting a pair of plug-in parts, the degree of freedom of the conductive shaft relative to the housing in the horizontal direction can be restricted; by setting a slot and a retaining part, the degree of freedom of the conductive shaft relative to the housing in the vertical direction can be restricted. Compared with the prior art, it replaces the previous fixed structure of the conductive shaft relative to the housing, making the installation of the conductive shaft more stable, solving the problem of unstable structure in the past, ensuring the working stability of the product, and the overall structure is simple and compact, which can save the material of parts, reduce the weight of the product, and has good economic benefits.

[0026] 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 are within the scope of protection of the present invention.

[0027] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or server that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or servers.

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] This utility model discloses a specific embodiment of a cable box for storing connecting cables. Please see [link / reference]. Figures 1 to 2 As shown, the junction box includes a housing 1, a conductive shaft 2, a conductive carrier 4, a wire clamp 5, a rotating disk 6, a torsion spring 7, a limiting component 8, and a connecting wire body 3.

[0030] In this embodiment, the housing 1 has a bottom shell 11 and a PCB panel 12 that is detachably connected to the bottom shell 11. The bottom shell 11 and the PCB panel 12 can be detachably connected by a snap-fit ​​structure or screws. A mounting cavity for loading electronic components is formed between the PCB panel 12 and the bottom shell 11. The conductive shaft 2, conductive carrier 4, wire clamp 5, rotating disk 6, torsion spring 7, limiting component 8 and connecting wire body 3 are all installed inside the mounting cavity.

[0031] Specifically, the conductive shaft 2 is fixedly installed inside the housing 1. The conductive carrier 4 is sleeved on the outer periphery of the conductive shaft 2 and electrically connected to the conductive shaft 2. The conductive carrier 4 can rotate relative to the housing 1 around the conductive shaft 2. The wire clamp 5 has a cable routing hole and is fixedly connected to the conductive carrier 4. The wire clamp 5 is used to hold the connecting wire body 3. Thus, the connecting wire body 3, the wire clamp 5, and the conductive carrier 4 can be regarded as a whole, which can rotate relative to the housing 1 and the conductive shaft 2. One end of the connecting wire body 3 is a free end that passes through the housing 1, and the other end of the connecting wire body 3 passes through the cable routing hole of the wire clamp 5 and is electrically connected to the conductive carrier 4. A rotating disk 6 is provided below the conductive carrier 4. The rotating disk 6 is fixedly connected to the conductive carrier 4. A torsion spring 7 is provided between the rotating disk 6 and the inner bottom surface of the housing 1 to drive the rotating disk 6 to rotate (rotate in the storage direction). During operation, the free end of the connecting wire body 3 is pulled by an external force. As the connecting wire body 3 is pulled out, it will drive the rotating disk 6 and the conductive carrier 4 to rotate around the conductive shaft 2. At this time, the torsion spring 7 is in a compressed state. When the connecting wire body 3 is no longer subjected to external force and there are no other components to obstruct the rotation of the rotating disk 6, the torsion spring 7 uses its own elasticity to drive the rotating disk 6 to rotate and guide the connecting wire body 3 to be stored inside the housing 1.

[0032] In addition, the cable box also includes a limiting component 8 located inside the housing 1 to restrict the rotation of the rotating disk 6. The limiting component 8 is mainly used to limit the rotating disk 6 to a specific position to facilitate the use of the cable box. Please see... Figure 8 The limiting assembly 8 includes a rotating member 81, a spring 82, and a gear 83. The rotating member 81 is rotatably mounted on the housing 1 (bottom shell 11). One end of the spring 82 is fixedly connected to the rotating member 81, and the other end of the spring 82 is fixedly connected to the bottom shell 11, so that the spring 82 can drive the rotating member 81 towards... Figure 8 The gear 83 meshes with the rotating component 81, causing the rotating component 81 to restrict the rotation of the rotating disk 6. It should be noted that only one spring 82 is used, which, compared to the traditional two springs, results in higher assembly efficiency, saves assembly time, and improves product production efficiency.

[0033] As an improvement, the conductive shaft 2 is fixedly connected to the housing 1 by a snap-fit ​​structure.

[0034] Please see Figure 3The bottom end of the conductive shaft 2 extends downwards into a pair of spaced elastic arms 21. Each elastic arm 21 has a downward-pointing insertion portion 22 at its bottom end, and each insertion portion 22 has a slot 23 on its outer surface. This can be understood as the bottom end of the elastic arm 21 extending downwards into a hook or barb, forming the aforementioned slot 23 between the hook or barb and the elastic arm 21. The spaced arrangement of the two elastic arms 21 not only restricts the horizontal rotation of the conductive shaft 2 relative to the housing 1 but also provides a certain deformation space for the elastic arms 21, facilitating the assembly of the conductive shaft 2 and the housing 1, thereby improving production and assembly efficiency.

[0035] Please see Figure 4 The bottom surface of the housing 1 (bottom shell 11) has paired and spaced-apart slots 13. Each slot 13 has an inner surface with a retaining portion 14 extending toward the slot 23. Preferably, the retaining portion 14 can be a sheet-like structure or a ring-like structure. Combined with... Figures 5 to 6 In the assembled state, the plug part 22 is inserted into the card hole 13, the holding part 14 is inserted into the card slot 23, and the bottom surface of the elastic arm 21 abuts against the inner bottom surface of the housing 1, thereby restricting the movement of the conductive shaft 2 relative to the housing 1 in the vertical direction. The degree of freedom of the conductive shaft 2 in the vertical direction can be adjusted according to the width of the card slot 23.

[0036] Please see Figure 6 and Figure 7 The upper inner surface of the locking hole 13 has an upwardly inclined first guide slope 15, while the lower outer surface of the elastic arm 21 has a downwardly inclined second guide slope 24. It should be noted that the length of the first guide slope 15 can be equal to or less than the circumference of the locking hole 13. Similarly, the length of the second guide slope 24 can be equal to or less than the circumference of the bottom surface of the elastic arm 21. In practical applications, the first guide slope 15 and the second guide slope 24 facilitate the insertion of the connector 22, providing convenience for assembly and reducing the likelihood of breakage of the connector 22 during assembly.

[0037] In addition, the PCB panel 12 (top surface of the housing 1) has a pair of spaced mounting holes, and the top of the conductive shaft 2 extends upward with a pair of spaced latching protrusions. The latching protrusions are inserted into the corresponding mounting holes to further limit the conductive shaft 2 and further improve the stability of the conductive shaft 2.

[0038] In this embodiment, the card hole 13 is fan-shaped, and similarly, the cross-sectional shape of the insertion part 22 is fan-shaped. In other embodiments, the shape of the card hole 13 and the cross-sectional shape of the insertion part 22 can also be one of a circle, rectangle, triangle or polygon, which can be selectively set according to actual needs.

[0039] The junction box in this embodiment, by providing paired plug-in portions 22, can restrict the degree of freedom of the conductive shaft 2 relative to the housing 1 in the horizontal direction. By providing slots 23 and holding portions 14, it can restrict the degree of freedom of the conductive shaft 2 relative to the housing 1 in the vertical direction. Compared with the prior art, it replaces the previous fixed structure of the conductive shaft 2 relative to the housing 1, making the installation of the conductive shaft 2 more stable, solving the problem of unstable structure in the past, ensuring the working stability of the product, and the overall structure is simple and compact, which can save the material of parts, reduce the weight of the product, and has good economic benefits.

[0040] Finally, it should be noted that the cable box for storing connecting cables disclosed in this utility model embodiment is only a preferred embodiment of this utility model and is only used to illustrate the technical solution of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
