Technical Field

[0001] The present invention belongs to the technical field of charging devices, and particularly relates to a modular magnetic USB interface. Background Art

[0002] At present, there are various specifications of charging cables on the market (such as USB-A, Type-C, etc.), which requires users to be equipped with multiple charging cables with different interfaces, resulting in material waste and environmental protection burden. At the same time, traditional charging cables lack the intelligent power-off function, and overcharging may cause potential safety hazards. Although there are some charging cables with compatible interfaces in the prior art, they have problems such as complex structure and insufficient safety performance.

[0003] In view of this, the present invention is specifically proposed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a USB interface with a modular structure, good compatibility and strong safety.

[0006] Further, the magnetic interface and the magnetic connector are electrically connected through corresponding pins.

[0007] Further, a control chip is provided inside the magnetic interface.

[0008] Further, a breathing light is provided on the magnetic interface.

[0009] The beneficial effects of the present invention are as follows: 1. Interface unification: Compatibility with USB and Type-C devices is achieved through the combination of adapter cables, reducing the types of wires and cables, and reducing material waste and environmental protection burden.

[0010] 2. Safe and reliable: An overcharging protection circuit is built-in, and the automatic power-off function eliminates potential safety risks.

[0011] 3. Optimized user experience: Magnetic connection is convenient and efficient, and the breathing light design enhances the interaction experience.

[0012] The above description is only an overview of the technical solution of the present invention. In order to be able to understand the technical means of the present invention more clearly and implement it in accordance with the content of the specification, the following describes the preferred embodiments of the present invention in detail in conjunction with the accompanying drawings.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the drawings. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0017] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] Please refer to Figure 1 , a modular magnetic-attraction USB interface shown in a preferred embodiment of the present application, includes a USB-A connector 1, a TYPE-C female head 2, a TYPE-C male head 3, and a magnetic-attraction interface 5.

[0019] Among them, the USB-A connector 1 and the TYPE-C female head 2 are electrically connected by an electric wire (not shown), the TYPE-C male head 3 and the magnetic-attraction interface 5 are also electrically connected by an electric wire, and the end of the magnetic-attraction interface 5 is magnetically connected to a magnetic-attraction connector 4.

[0020] Specifically, the magnetic-attraction interface 5 and the magnetic-attraction connector 4 are electrically connected through corresponding pins.

[0021] More specifically, a breathing lamp 6 is provided on the magnetic-attraction interface 5, and a control chip is also provided inside the magnetic-attraction interface 5.

[0022] Through modular design, the electronic device and the power adapter can be arbitrarily combined and connected. It can be used as a USB-A connector - TYPE-C male data cable, a USB-A connector - TYPE-C female data cable, or a TYPE-C - male - TYPE-C male data cable, with wide applicability.

[0023] It should be noted that the control chip is used to monitor the charging voltage and current in real time, and cut off the power supply to prevent overcharging after detecting the charging completion. The breathing light is used to display the charging status.

[0024] Working principle: When in use, connect the device and the adapter with the corresponding interface according to the interface models of the electronic device and the power adapter. When charging starts, the breathing light flashes at a low frequency, and the control chip monitors the voltage / current in real time; when the battery is nearly full, the breathing light flashes at a high frequency; after being full, the indicator light stays on constantly, and the control chip cuts off the charging circuit and enters the standby state.

[0025] The technical features of the above-described embodiments can be arbitrarily combined. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0026] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
