Description

Technical Field

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

[0002] A charging cable consists of an inner core wire and an outer flexible protective sheath. The core wire is responsible for power transmission, while the flexible protective sheath protects the core wire and extends the cable's lifespan. In use, the power-receiving end of the charging cable connects to a power adapter or other power supply device, while the power-supplying end connects to the device requiring charging, such as a mobile phone or tablet, enabling efficient power transfer. Although technological advancements have continuously optimized charging cable designs—for example, by adding electromagnetic interference shielding layers to improve data transmission quality or incorporating overcurrent protection mechanisms to enhance safety—the primary function of a charging cable remains relatively simple: power transfer between the power supply device and the device being charged. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a multi-functional charging cable.

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-functional charging cable, including a core wire and a flexible protective sleeve that is sleeved on the outside of the core wire. A gap is left between the flexible protective sleeve and the core wire so that the flexible protective sleeve can be axially gathered together to form folds.

[0005] Furthermore, the flexible protective sleeve is specifically an elastic protective sleeve capable of undergoing axial elastic deformation.

[0006] Furthermore, the flexible protective sleeve is specifically a silicone protective sleeve.

[0007] Furthermore, the radial thickness of the gap is 0.2 to 0.5 mm.

[0008] Furthermore, an anti-sticking powder layer is provided between the flexible protective sleeve and the core wire.

[0009] Furthermore, the powder layer is specifically coated on the outside of the core wire.

[0010] Furthermore, the radial thickness of the powder layer is smaller than that of the voids.

[0011] Furthermore, a magnetic material layer is provided that allows the charging cable to be wound and stored magnetically.

[0012] In addition to its power transmission function, the charging cable of this utility model also has an entertainment function. The operation is as follows: The user holds the rear end of the flexible protective sleeve with their first hand and keeps it still. The user then extends their second hand to the front of the first hand and similarly holds the flexible protective sleeve. The second hand then moves axially forward along the flexible protective sleeve, pushing the portion of the sleeve located in front of the second hand. Because there is a gap between the flexible protective sleeve and the core wire that allows the sleeve to axially gather together to form folds, the portion of the sleeve located in front of the second hand gathers together axially to form folds under the push of the second hand. When the second hand passes over the folds, the folds are no longer pushed forward and instantly return to their original shape, producing a crisp sound, providing the user with auditory feedback and enjoyment.

[0019] The present invention will be further described in detail below with reference to specific embodiments.

[0020] See charging cable Figure 1 It includes a core wire 1, with an inner core 11 and an outer magnetic material layer 12. A silicone protective sleeve 2 is fitted over the core wire 1, with a radial gap 3 of 0.2–0.5 mm between the silicone protective sleeve 2 and the core wire 1. See Figure 2 The charging cable has a power receiving end 101 and a power supply end 102 at each end. In use, the power receiving end 101 connects to a power supply device such as a power adapter, and the power supply end 102 connects to a mobile phone, tablet, or other device that needs charging, thus achieving efficient power transfer. When storing, the charging cable is... Figure 2 As shown, it is wound into multiple loops stacked on top of each other, utilizing magnetic material layer 12 (see...). Figure 1 The magnetic force makes each adjacent two turns like Figure 3The tight adhesion shown in the diagram achieves a stable storage effect.

[0021] This charging cable is a multi-functional charging cable. In addition to its power transmission function, it also has entertainment functions. Operation is as follows:

[0022] See Figure 4 The user uses two fingers 31 of their first hand to pinch the rear end 21 of the silicone protective sleeve 2, causing it to indent inwards, and then holds this position. The user then uses two fingers 32 of their second hand to extend to the front of the first hand and similarly pinch the rear end 21 of the silicone protective sleeve 2. The user then moves the two fingers 32 of the second hand axially forward along the silicone protective sleeve 2, thereby axially pushing the portion 25 of the silicone protective sleeve 2 located in front of the two fingers 32. During this process, the portion 26 of the silicone protective sleeve 2 located behind the two fingers 32 undergoes axial elastic stretching under the pull of the two fingers 32. (See...) Figure 5 Because there is a radial thickness of 0.2 to 0.5 mm between the silicone protective sleeve 2 and the core wire 1, this gap 3 is sufficient for the silicone protective sleeve 2 to detach from the core wire 1 and axially gather together to form a fold 4. Therefore, the portion 25 of the silicone protective sleeve 2 located in front of the two fingers 32 of the second hand will axially gather together to form a fold 4 under the pushing action of the two fingers 32. Subsequently, when the two fingers 32 of the second hand pass over the fold 4, the fold 4 is no longer pushed forward and will instantly recover, producing a crisp sound, providing the user with auditory feedback and enjoyment.

[0023] See Figure 1 The outer side of the core wire 1 is coated with an anti-adhesion powder layer 5, and the radial thickness of the anti-adhesion powder layer 5 is less than that of the gap 3. During the production and assembly of the charging cable, the core wire 1 needs to be inserted into the silicone protective sleeve 2. During this process, the powder layer 5 separates the core wire 1 from the silicone protective sleeve 2 to prevent excessive friction or adhesion between the two due to contact, thus ensuring a smooth assembly process.

[0024] See Figure 5 In this embodiment, a silicone protective sleeve 2 is fitted over the outer side of the core wire 1. The silicone protective sleeve 2 serves as a flexible protective sleeve to protect the core wire 1, and also as an elastic protective sleeve, undergoing axial elastic deformation when pulled by two fingers 32 of a second hand. Other embodiments may use an elastic material such as rubber instead of silicone as the flexible protective sleeve to protect the core wire.

[0025] In a non-preferred embodiment, a non-elastic flexible material such as PVC can be used instead of silicone as a flexible protective sleeve to protect the core wires. See Figure 6Although the flexible protective sleeve is inelastic and cannot be stretched axially like silicone, because there is a gap 3 with a radial thickness of 0.2 to 0.5 mm between the silicone protective sleeve 2 and the core wire 1, when the part of the flexible protective sleeve 2 located on the back side 26 of the second hand is pulled forward by the two fingers 32 of the second hand: the rear end 21 of the flexible protective sleeve 2 will be pulled forward a small distance. Therefore, the part 25 of the flexible protective sleeve 2 located in front of the two fingers 32 of the second hand can still be axially gathered together to form a small wrinkle 4 under the pushing of the two fingers 32 of the second hand.

[0026] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
