[0002] With the continuous progress of technology and the wide application of smart phones, great convenience has been brought to people's daily life. The mobile phone charger has become one of the essential electronic accessories for people at home or when going out. Currently, different mobile phones have different charging powers, including high power and low power. Most of the current chargers cannot adjust the charging power according to the demand by themselves, which is very inconvenient. Later, a charger that can adjust the power emerged. However, its structural design is unreasonable, and users are prone to accidentally touch the adjustment switch. For example, when the charger needs to be unplugged, the power may be accidentally turned up, which is likely to damage the mobile phone. Therefore, in view of the above problems, it is necessary to propose a new solution. Summary of the Utility Model

[0005] A high-power charger with high safety includes a housing, a circuit board, a high-power switching button, and a power status indicator. The circuit board is arranged inside the housing. The circuit board is provided with a leakage protection module. The front end of the housing is provided with two pins for connecting to a socket, and the pins are electrically connected to the circuit board. The rear end face of the housing is provided with a socket for docking with the connector of the charging cable. The high-power switching button is electrically connected to the circuit board, and the high-power switching button is arranged on the housing and exposed on the surface of the rear end face of the housing. The power status indicator is electrically connected to the circuit board and exposed on the outer surface of the housing.

[0006] As a preferred scheme, a shallow groove is recessed on the rear end face of the housing. The socket, the high-power switching button, and the power status indicator are all located in the groove. Moreover, the high-power switching button and the power status indicator are respectively arranged on both sides of the socket.

[0007] As a preferred scheme, the circumferential corners of the bottom surface of the shallow groove are rounded.

[0008] As a preferred scheme, a silicone protective sleeve is suitably sleeved outside the high-power switching button.

[0009] As a preferred scheme, a silicone outer sleeve is sleeved on the outer surface of the housing.

[0010] As a preferred solution, a wire buckle is integrally formed and connected to the silicone outer cover.

[0011] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions, the main points are as follows:

[0012] Through the high-power switching button, the switching between high-power and low-power charging can be realized. In addition, in order to avoid the high-power switching button being accidentally touched and causing incorrect charging, which may damage the mobile phone or even cause an explosion, the high-power switching button is designed on the rear end face of the outer shell. This position is not easily accidentally touched. Moreover, by setting a leakage protection module, damage to the circuit board caused by liquid short-circuit can be avoided. This application can achieve high-power and low-power switching charging, can prevent users from accidentally touching the high-power switching button for adjusting the power, and has high safety.

[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the following will further detail the present utility model in combination with the drawings and implementation examples. It should be understood that the specific implementation examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0021] Please refer to Figures 1 to 3 Figures 1 to 3 , an embodiment of the present utility model provides a high-power charger with high safety, which includes a housing 10, a circuit board (not shown in the figure), a high-power switching button 20, and a power status indicator light 30. The circuit board is arranged inside the housing 10, and a leakage protection module is provided on the circuit board. Two pins 11 for connecting to a socket are provided at the front end of the housing 10, and the pins 11 are electrically connected to the circuit board. An insertion port 12 for docking with the connector of the charging cable is provided on the rear end face of the housing 10. The high-power switching button 20 is electrically connected to the circuit board, and the high-power switching button 20 is arranged on the housing 10 and exposed on the surface of the rear end face of the housing 10. The power status indicator light 30 is electrically connected to the circuit board and exposed on the outer surface of the housing 10.

[0022] Through the high-power switching button, the switching between high-power and low-power charging can be realized. In addition, in order to prevent the high-power switching button 20 from being accidentally touched and causing incorrect charging, which may damage or even explode the mobile phone, the high-power switching button 20 is designed on the rear end face of the housing 10. This position is not easily accidentally touched. Moreover, by setting the leakage protection module, the damage to the circuit board caused by liquid short circuit can be avoided. This application can realize the switching between high-power and low-power charging, can prevent the user from accidentally touching the high-power switching button 20 for adjusting the power, and has high safety.

[0023] Furthermore, a shallow groove 13 is recessed on the rear end face of the housing 10. The insertion port 12, the high-power switching button 20, and the power status indicator light 30 are all located in the groove. Moreover, the high-power switching button 20 and the power status indicator light 30 are respectively arranged on both sides of the insertion port 12. The groove can make the high-power switching button 20 sink, so that the periphery of the groove is higher than the high-power switching button 20, thereby further reducing the probability of accidental touch. In addition, the positional relationship among the insertion port 12, the high-power switching button 20, and the power status indicator light 30 is reasonably designed, which can make reasonable use of space.

[0024] Furthermore, the circumferential corners of the bottom surface of the shallow groove 13 are rounded. The rounded corner design is convenient for cleaning. If it is a right-angle corner, it is easy to hide dirt and is not easy to clean.

[0025] Furthermore, a silicone protective cover (not shown in the figure) is externally and adaptively sleeved on the high-power switching button 20. The silicone protective cover can prevent water, avoiding liquid from entering the inside of the housing 10 through the high-power switching button 20 and short-circuiting the circuit board. It should be noted that this is a protection method and structure in the prior art, and will not be elaborated here.

[0026] Furthermore, a silicone outer sleeve 40 is sleeved on the outer surface of the housing 10. Adding the silicone outer sleeve 40 can improve the feel of holding this product, facilitating the user to hold the product and insert it into the socket.

[0027] Furthermore, a wire buckle 41 is integrally formed and connected to the silicone outer sleeve 40. By designing the wire buckle 41, it can facilitate the user to store and organize the charging cable (or data cable). Specifically, when it is necessary to store and organize the charging cable, wind the charging cable around the housing 10 in the winding direction of the front and rear end faces of the housing 10 (the coil is located between the two aforementioned pins 11), and finally buckle the last small section of the charging cable on the wire buckle 41.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the principle of the present utility model shall be included within the protection scope of the present utility model.
