[0026] See Figure 1 and Figure 2In one embodiment of this utility model application, a charging cable designed to prevent detachment is disclosed, comprising a data cable body 10, a connector 20, and a limiting member 30. The end of the data cable body 10 is provided with a charging head 11 for connecting to a charging device. The connector 20 is disposed on the data cable body 10. The straight-line distance between the connector 20 and the charging head 11 is a first distance. The limiting member 30 is connected to the connector 20. The limiting member 30 is provided with a connector 40 for connecting to the charging device, and the straight-line distance between the connector 40 and the connector 20 is a second distance. The second distance is less than the first distance.

[0027] The charging devices disclosed in this embodiment include, but are not limited to, electronic devices such as mobile phones, computers, power banks, and smartwatches. The charging cable disclosed in this embodiment is used to connect to an external power source to charge the aforementioned electronic devices. On the other hand, the charging devices disclosed in this embodiment also include chargers, adapters, and other converters. The connection stability between the data cable body 10 and the charger or adapter is increased by setting a limiting member 30.

[0028] Specifically, the anti-loosening charging cable disclosed in this embodiment increases the connection with the charging device by setting a limiting member 30 on the data cable body 10. When the charging head 11 is inserted into the charging device for charging or data transmission, the connector 40 is simultaneously connected to the charging device, increasing the connection strength. The connector 40 disclosed in this embodiment can be fixed to the charging device by means of adhesive bonding, overlapping, magnetic connection, etc. Since the second distance is smaller than the first distance, when subjected to a pulling force, the limiting member 30 is stressed and in a taut state, while the data cable body 10 between the connector 20 and the charging head 11 is not stressed and remains in a slack state.

[0029] Therefore, during the charging process, the data cable body 10 is prevented from becoming loose due to force, which helps to maintain the stability of the charging head 11 and improves the stability and safety of the charging process.

[0030] For example, when charging a mobile phone, the charging head 11 is inserted into the interface on the side of the phone, and the connector 40 is bonded to the phone's casing. At this time, since the distance between the connector 40 and the connector 20 is shorter than the distance between the charging head 11 and the connector 20, when a pull occurs, the limiting member 30 tightens first to bear the pressure, while the data cable body 10 remains relaxed.

[0031] In addition, by reducing the pulling on the data cable body 10 in this embodiment, it is also beneficial to reduce damage to the data cable body 10 and extend the service life of the charging cable.

[0032] Specifically, as another embodiment of this application, the charging head 11 is disclosed to be any one of a Type-C port, a Micro-USB port, a Lightning port, a USB-A port, and a USB-PD port. The flexible design of multiple types of charging heads 11 can adapt to different usage needs, increase the practicality of the product, and enhance its market value.

[0033] like Figure 2 As shown in another embodiment of this invention, a charging plug 12 is provided at one end of the data cable body 10 opposite to the charging head 11. The charging plug 12 can be any one of a Type-C port, a Micro-USB port, a Lightning port, a USB-A port, or a USB-PD port. In this embodiment, the data cable body 10 is connected to an adapter and a power device at both ends, thus allowing for flexible design of various types of charging plugs 12 to match and combine with the charging head 11, further improving practicality and meeting various usage needs.

[0034] For example Figure 2 As shown, in another embodiment of this application, the connector 20 includes a shaft 21 protruding from the data cable body 10; the limiting member 30 includes a connecting piece 31 and an extension piece 32, one end of the connecting piece 31 is provided with a mounting hole for inserting the shaft 21, and the other end is provided with a first collar 311; one end of the extension piece 32 is provided with a second collar 321, and the other end is connected to the connector 40; the second collar 321 is connected in series with the first collar 311.

[0035] In this embodiment, the connecting piece 31 is hinged to the shaft 21, allowing the connecting piece 31 to rotate freely. Simultaneously, the connecting piece 31 and the extension piece 32 are movably connected via a first collar 311 fitted with a second collar 321, meaning the connecting piece 31 and the extension piece 32 can rotate relative to each other, flexibly adjusting their direction. Therefore, the entire limiting member 30 has high flexibility, allowing free rotation and improving usability.

[0036] During charging, the connection between the limiting member 30 and the charging device is flexible and can rotate freely, so it does not restrict the docking direction between the charging head 11 and the charging device. When a pulling force is generated during charging (such as when the phone is dropped), the limiting member 30 will tighten, thus protecting the data cable body 10 and maintaining stability.

[0037] As can be seen, the charging cable disclosed in this embodiment balances flexibility and stability in use.

[0038] For example Figure 2As shown, in another embodiment of this invention, the data cable body 10 includes a cable body, a plug 13, a braided cord sleeve 14, and a protective sleeve 15. The plug 13 is connected to the cable body. The charging head 11 is located at the end of the plug 13. The braided cord sleeve 14 is wrapped around the cable body. The protective sleeve 15 is fitted onto the braided cord sleeve 14. One end of the protective sleeve 15 is connected to the plug 13, and the other end is provided with the shaft 21. The shaft 21, the protective sleeve 15, and the plug 13 are integrally formed.

[0039] In this embodiment, the data cable body 10 adopts a structure in which a braided rope sleeve 14 wraps around the cable body, taking into account both flexibility and safety. The cable body is connected to the plug 13 to realize current transmission. A protective sleeve 15 is covered at the end of the braided rope sleeve 14 to increase local strength, so as to facilitate the setting of the shaft 21 and the connection of the limiting member 30, making the structure at the connection between the limiting member 30 and the data cable body 10 stable and improving the charging cable's ability to withstand external pulling forces.

[0040] Specifically, the shaft 21, protective sleeve 15, and plug 13 can all be integrally molded and made of plastic materials, which can increase insulation performance, simplify the production process, and improve the stability of the structure.

[0041] Specifically, in another embodiment of this invention, the charging head 11 and the plug 13 are magnetically connected. The detachable assembly of the charging head 11 and the plug 13 facilitates quick assembly and disassembly of the charging device, making it convenient to use.

[0042] like Figure 3 As shown, in another embodiment of this application, the connecting seat 20 includes a first connecting hole 22; the connecting member 40 includes a second connecting hole 41; the limiting member 30 includes a limiting chain 33, one end of which is connected in series with the first connecting hole 22 and the other end is connected in series with the second connecting hole 41.

[0043] The limiting chain 33 disclosed in this embodiment serves to connect the connector 40 and the connector 20. The limiting chain 33 maintains flexibility when not under stress. Therefore, during normal charging, both the limiting chain 33 and the data cable body 10 remain in a slack state, allowing free movement, which facilitates the connection of the charging head 11 to the charging device. During charging, in the event of unexpected pulling, the limiting chain 33 tightens to withstand the pulling force and protect the data cable body 10.

[0044] For example Figure 3As shown in another embodiment of this application, the anti-detachment charging cable also includes a long lanyard 50. One end of the long lanyard 50 is connected to the limiting chain 33, and the other end is connected to the data cable body 10. The length of the long lanyard 50 is greater than the length of the data cable body 10. In this embodiment, the long lanyard 50 is longer than the data cable body 10, so the long lanyard 50 and the data cable body 10 together form a loop, allowing the user to wear the charging cable around their neck or sling it diagonally across their body, thus maintaining the stability of the data cable and freeing up their hands.

[0045] During charging, the charging device is connected to the connector 40, and the limiting member 30 is subjected to force, which can maintain the connection between the charging device and the data cable body 10. In other words, the charging device can be hung on the body for charging, increasing the portability of the charging cable and the charging device.

[0046] Specifically, as another embodiment of this application, the charging device is disclosed to include a device body and a protective shell, the protective shell being wrapped around the device body; the connector 40 is used to be inserted between the device body and the protective shell.

[0047] The device body disclosed in this embodiment can be a smart terminal such as a mobile phone or tablet computer. Installing a protective case on a mobile phone or tablet computer can increase impact resistance and enhance protection. Since the protective case and the device body are usually connected by a snap-fit, the connector 40 is inserted between the protective case and the device body, and the connection is achieved through friction. This connection method does not require additional adhesive materials or connection structures, is simple to operate, easy to disassemble, and has a wide range of applications, thus balancing flexibility and practicality.

[0048] Specifically, in another embodiment of this invention, the connector 40 is disclosed to be elongated, such as... Figure 1 and Figure 2 As shown, the connector 40 and the limiting member 30 are arranged in a "T" shape. In this embodiment, the connector 40 connects to the charging device through friction. Therefore, the connector 40 is elongated to increase the surface area and improve connection stability. Simultaneously, the "T" shape of the connector 40 and the limiting member 30 ensures that when the connector 40 is subjected to frictional tension, the direction of the force is the same as the length direction of the limiting member 30. This maintains tension and ensures that the limiting member 30 bears all the tensile force, protecting the data cable body 10 and maintaining the stability of the charging head 11.

[0049] In the application scenario of charging a mobile phone, the connector 40 is inserted between the phone case and the phone body. The extension piece 32 is connected to the middle of the connector 40, extends out from the charging port of the phone, and is integrated with the connector 31. During charging, the data cable body 10 is plugged into the charging port of the phone, so the length direction of the limiting member 30 coincides with the length direction of the data cable body 10. On this basis, when the phone is pulled by an external force, the limiting member 30 is stretched, while the data cable body 10 remains in a relaxed state, which can prevent it from coming loose.

[0050] like Figure 2 As shown, in another embodiment of this invention, a suction cup 42 is provided on the connector 40, which is used to adsorb the charging device. The suction cup 42 disclosed in this embodiment can be directly adsorbed onto the back cover of the charging device or onto the protective cover 15, making it simple and convenient to use. Additionally, in another embodiment of this invention, an adhesive layer can also be provided on the connector 40 for bonding to the charging device.

[0051] This application also discloses a charging device, which includes a non-detachable charging cable as described in any of the above.

[0052] In summary, this application discloses an anti-detachment charging cable, comprising a data cable body 10, a connector 20, and a limiting member 30. The end of the data cable body 10 is provided with a charging head 11 for connecting to a charging device. The connector 20 is disposed on the data cable body 10. The straight-line distance between the connector 20 and the charging head 11 is a first distance. The limiting member 30 is connected to the connector 20. The limiting member 30 is provided with a connector 40 for connecting to the charging device. The straight-line distance between the connector 40 and the connector 20 is a second distance; the second distance is less than the first distance. When subjected to a pulling force, the limiting member 30 is stressed and remains taut, while the data cable body 10 between the connector 20 and the charging head 11 remains relaxed. Therefore, during charging, the data cable body 10 is prevented from loosening due to stress, which helps maintain the stability of the charging head 11, improves the stability and safety during charging, and extends the service life of the charging cable.

[0053] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0054] It should be noted that this utility model uses an anti-detachment charging cable and charging device as an example to introduce the specific structure and working principle of this utility model, but the application of this utility model is not limited to anti-detachment charging cables and charging devices, and can also be applied to the production and use of other similar workpieces.
