Technical Field

[0001] This utility model relates to the field of charger technology, specifically a charging cable. Background Technology

[0002] As an essential accessory for charging electronic devices, chargers commonly present the following technical problems in daily use: First, because charging cables need to meet portability requirements, they are usually made of highly flexible materials (such as TPU, silicone, etc.). These materials are prone to memory deformation when bent, causing them to remain bent after storage and easily form knots or tangles during use. Utility Model Content

[0003] In order to solve the technical problems in the prior art, this utility model proposes a charging cable.

[0004] The technical solution adopted in this utility model is:

[0005] This utility model proposes a charging cable, comprising:

[0006] The cable plug has a plug at one end for connecting to the charger and a cable at the other end.

[0007] A pair of long brackets are rotatably connected to the two sides of the wire plug in the middle, and each long bracket has a wire winding groove at one end, and the gap between the two long brackets forms a wire passage gap.

[0008] A winding seat is rotatably connected to the other end of a pair of elongated supports, and the surface of the winding seat is provided with wavy grooves for winding.

[0009] Furthermore, an L-shaped bending block is provided on the inner side of one end of each of the two elongated supports, and the area between the end of the elongated support and the bending block thereon forms the winding groove, and the gap between the two bending blocks forms the wire passage gap.

[0010] Furthermore, the wire plug has connecting posts on both sides, and threaded holes in the middle of the connecting posts. The long bracket has connecting holes at the corresponding positions of the connecting posts. A screw passes through the connecting holes and is threadedly connected to the threaded holes, so that the wire plug can rotate around the screw as an axis.

[0011] Furthermore, the winding seat is also provided with connecting posts on both sides, so that the winding seat can rotate around the threaded hole of the connecting post as an axis.

[0012] Furthermore, the winding base is equipped with a lighting lamp, and the winding base is electrically connected to the wire plug.

[0033] 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.

[0034] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0035] Because charging cables need to meet portability requirements, they are usually made of highly flexible materials (such as TPU, silicone, etc.). These materials are prone to memory deformation when bent, causing them to remain bent after storage and easily form knots or tangles when used.

[0036] In this regard, such as Figure 1 As shown, this utility model proposes a charging cable, including: a cable plug 2, a pair of elongated brackets 1, and a winding base 3. The cable plug 2 is square, with a plug 23 at one end for connection to a charger 7; the other end is connected to the cable 21, serving as the fixed end of the cable 21. The middle portions of the pair of elongated brackets 1 are rotatably connected to the two sides of the cable plug 2, allowing the cable plug 2 to rotate freely between the two brackets. Each elongated bracket 1 has a bending block 11 at one end forming a winding groove, and a gap 12 is left between the bending blocks 11 at the two ends of the elongated brackets 1 to guide the cable 21 through or fix its position. The winding base 3 is rotatably connected to the other end of the elongated brackets 1, and its surface has a wavy groove 31. The undulating structure of the groove 31 can hold the cable 21 in place, facilitating the orderly winding of the cable 21 onto the surface of the winding base 3.

[0037] The wire insertion block 2 is rotatably connected to the long bracket 1, and the winding groove and wire passage gap 12 at the end of the bracket are used to achieve the following: Figure 2 , 3 As shown, when storing, rotate the cable plug 2 to a position parallel to the long bracket 1, allowing the cable 21 to pass through the cable passage 12, and then wind it back and forth into the wavy groove 31 and winding slot of the winding base 3, completing the storage and making the cable 21 compactly folded, preventing the cable 21 from becoming tangled. When using, unfold the stored cable 21, and rotate the cable plug 2 to adjust the direction of the plug 23 to connect and engage with the charger 7. This structure enables the cable 21 to be quickly stored and unfolded, while protecting the cable 21 from bending damage, saving storage space and being easy to operate.

[0038] In a specific embodiment, each of the two elongated brackets 1 has an L-shaped bending block 11 on its inner side at one end. The L-shaped bending block 11 and the end of the elongated bracket 1 form a winding groove extending perpendicular to the inner side of the elongated bracket 1, used to hold the wire 21 in place and prevent slippage. The L-shaped bending blocks 11 of the two brackets are positioned opposite each other, and the gap between their ends forms a wire passage gap 12, allowing the wire 21 to pass through this gap and ensuring a smooth path for the wire 21 when it is retracted or extended. The L-shaped structure enhances the connection stability between the bending block 11 and the bracket, while the cooperation between the winding groove and the wire passage gap 12 accurately positions the wire 21, preventing offset or knotting during winding.

[0039] In a specific embodiment, connecting posts 5 are provided at the middle positions of both sides of the wire plug 2. A threaded hole is provided at the center of the outer end face of the connecting post 5 facing the elongated bracket 1. A connecting hole is opened in the middle of the elongated bracket 1, and a screw 6 passes through the connecting hole from the outside of the bracket and is tightened into the threaded hole for fixation. This allows the wire plug 2 to rotate around the screw as a central axis. This connection structure ensures a stable connection between the wire plug 2 and the elongated bracket 1, and also allows for angle adjustment via the screw connection, facilitating rotation and adjustment of the plug 23's direction. The cooperation between the screw 6 and the connecting post also prevents the connecting post 5 from dislodging from the bracket during rotation, improving the overall durability and reliability of the structure.

[0040] In a specific embodiment, connecting posts 5 are also provided on both sides of the winding base 3, and their internal structure is consistent with the connecting posts 5 of the wire insertion block 2. A connecting hole is opened at the corresponding position on the other end of the long bracket 1, and a screw 6 is passed through the bracket hole and screwed into the threaded hole to tighten it, so that the winding base 3 can rotate around the threaded hole as the central axis.

[0041] The winding base 3 integrates a light, which is electrically connected to the plug 23 of the wire connector 2. When the plug 23 is connected to a power source, the light can be turned on automatically or manually (depending on the specific circuit design) to provide auxiliary lighting for the surrounding environment. The light also serves as an indicator of the charging status; when the plug 23 is powered on, the light illuminates, indicating to the user that the device is currently in a usable state. Furthermore, due to the rotatable nature of the winding base 3, the direction of the light's illumination can be adjusted.

[0042] Preferably, the lighting fixture has the following structure: a lighting fixture is installed inside the winding base 3, and the outer shell portion of the winding base 3 with the wavy groove 31 is made into a transparent shell, so that the direction of illumination of the lighting fixture can be adjusted by rotating the winding base 3, and the wavy groove 31 can also play a role in diffuse reflection. By combining the functionality of the cable 21 with the lighting requirements, the practical application scenarios of the charging cable 21 are expanded without adding additional components, and it is especially suitable for quickly locating and organizing the cable 21 at night or in complex environments.

[0043] In the first embodiment, the lighting lamp and the plug 23 of the wire plug 2 are electrically connected through two symmetrically arranged conductive plates 4. Each conductive plate 4 has a circular connecting cap 41 at both ends, with a through hole in the center of the connecting cap 41. The conductive plate 4, through the connecting cap 41, is fitted onto the outside of the connecting posts 5 on both sides of the winding base 3 and the wire plug 2. That is, the connecting posts 5 serve as conductive terminals for conductive connection and also as rotating shafts. Screws 6 pass through the connecting holes of the elongated bracket 1 through the through holes of the connecting caps 41 and are threaded into the threaded holes inside the connecting posts 5. The outer wall of the connecting cap 41 is in close contact with the surface of the connecting posts 5, forming a stable electrical conduction path. This ensures the circuit connection between the winding base 3 and the wire plug 2 without affecting the flexible rotation of the components.

[0044] like Figure 4 As shown, in the second embodiment, specifically, the conductive sheet 4 is embedded inside the elongated bracket 1 (which can be manufactured by injection molding). A connecting groove is provided on the inner side of the elongated bracket 1 corresponding to the position of the connecting post. The inner wall of the connecting groove is the connecting cap 41 part of the conductive sheet 4. After the connecting post 5, serving as a conductive terminal, is inserted into the connecting groove, it contacts the connecting cap 41 of the conductive sheet 4 to form a conductive connection. This embedded structure simplifies the assembly process and avoids the problems of easy wear or poor contact of traditional wires in rotating mechanisms, ensuring stable operation of electrical functions such as lighting under arbitrary angle adjustments.

[0045] In a further embodiment, the connecting post 5 has an annular groove surrounding its central threaded hole, and a conductive spring 25 is disposed within the annular groove. The conductive spring 25 forms an elastic contact between the connecting post 5 and the connecting cap 41 of the conductive plate 4, ensuring a stable electrical connection when the connecting post 5 rotates relative to the conductive cap. Simultaneously, the spring's cushioning effect reduces wear caused by direct friction between metal parts. This design enhances the conductive reliability of the winding base 3 and the wire insertion block 2 during rotation, especially during frequent angle adjustments or long-term use, preventing lamp failure due to poor contact and extending the structural lifespan.

[0046] In specific embodiments, such as Figure 5As shown, a ring of protrusions 13 is provided on the inner side of the elongated bracket 1 at the position around the rotation centerline of the cable plug 2. The protrusions 13 are distributed in a ring along the inner wall of the bracket, i.e., in a sawtooth shape. The two sides of the cable plug have slots 22 that can be engaged with these protrusions. By increasing the coefficient of friction of the contact surface, the free rotation of the cable plug 2 is effectively restricted under non-active operation. For example, when the user adjusts the direction of the plug 23, the friction between the protrusions 13 and the outer wall of the cable plug 2 can fix the current angle, preventing the plug 23 from shifting due to slight external force. This design ensures flexible rotation of the plug while improving stability and accuracy during use, and is especially suitable for scenarios requiring a fixed charging angle.
