[0002] With technological advancements, mobile phones and other electronic devices have become essential to people's lives. Power adapters are commonly used to charge mobile phones and other electronic devices. A power adapter typically consists of a housing, transformer, inductor, capacitor, control IC, PCB, and other components. It works by converting AC input into DC output. It converts AC power from an outlet or other power source into the DC power required by the device, providing power to the device. Its output voltage is typically the DC voltage required by the device.

[0003] As described in the patent application CN207994938U, which describes a power adapter with a rotatable plug, various portable electronic devices currently operate from rechargeable batteries. Examples of such portable electronic devices include mobile phones, portable media players, and personal digital assistants. To facilitate charging of rechargeable batteries, portable electronic devices are often sold together with a power adapter. Typically, a power adapter includes a power plug for coupling to an AC outlet. The power plug is a critical component of the power adapter, which must meet certain safety regulations. The power adapter also includes electronic circuitry that converts AC power received from the AC outlet into DC power and outputs the DC power via a cable with a connector. The cable connector connects to the portable electronic device and allows the portable electronic device to receive DC power for powering the portable electronic device or charging a rechargeable battery. However, in real life, some sockets have different designs, and when multiple electrical plugs are plugged into the same socket, they can interfere with each other due to the orientation of the plugs.

[0004] In summary, in the prior art, the power adapter has the problem of being difficult to use due to the direction of the plug during use. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6 , an angle-adjustable power adapter, comprising a shell 1 and a power cord 2 arranged on the shell 1. The shell 1 in this application is composed of components such as a transformer, an inductor, a capacitor, a control IC, and a PCB board. The power cord 2 can be electrically connected to the PCB board. An assembly cylinder 3 is fixedly connected to one side of the shell 1. An insulating seat 4 is rotatably connected to the assembly cylinder 3. A power plug 5 is provided on the insulating seat 4. The insulating seat 4 can improve the insulation of the connection of the power plug 5. A rotating conductive component 6 is provided in the shell 1 and the assembly cylinder 3. The rotating conductive component 6 is connected to the power plug 5. When the power plug 5 is adjusted in angle, the rotating conductive component 6 can ensure the effectiveness of the conductive connection between the power plug 5 and the PCB board. A spring sheet 7 is provided on the insulating seat 4, and the spring sheet 7 is elastically clamped on the inner wall of the assembly cylinder 3.

[0026] The power plug 5 is fixedly connected to one end of the insulating base 4 , and one end of the power plug 5 extends to the other end of the insulating base 4 . The fixed penetration of the power plug 5 can facilitate electrical connection with the rotating conductive component 6 .

[0027] A sealing ring 8 is provided on the outer surface of the insulating seat 4, and the insulating seat 4 is rotatably connected to the assembly tube 3 through the sealing ring 8. The setting of the sealing ring 8 can make the insulating seat 4 have a sealed rotation connection effect in the assembly tube 3, while facilitating the control of the relative rotation between the insulating seat 4 and the assembly tube 3, and can also ensure the sealing of the connection.

[0028] The rotating conductive component 6 includes a mounting plate 61, which is fixedly connected to the inner wall of the shell 1. A collector ring 62 is embedded on the mounting plate 61. The input end of the collector ring 62 is fixedly connected to a conductive sheet 63. The conductive sheet 63 is fixedly connected to one end of the power plug 5. The collector ring 62 is an existing power connection component and will not be described in detail here. The output end of the collector ring 62 can be connected to the PCB board through a wire. In this way, the collector ring 62 is conductively and fixedly connected to the power plug 5 through the conductive sheet 63. When the power plug 5 is inserted into the socket, the effect of rotary power supply can be achieved.

[0029] The other end of the insulating seat 4 is fixedly connected to a fixing block 71, and one end of the spring piece 7 is fixedly connected to the fixing block 71. The other end of the spring piece 7 is arranged in a coil head. The coil head of the spring piece 7 is arranged in a spiral structure. The spiral structure allows the coil head of the spring piece 7 to be easily and elastically engaged in the slot 9. When the insulating seat 4 is rotated, the coil head of the spring piece 7 can be elastically deformed, and the coil head of the spring piece 7 pops out from the previous slot 9 and slides on the inner wall of the assembly cylinder 3. When it is rotated into place, the coil head of the spring piece 7 is engaged in the next slot 9 for elastic engagement.

[0030] A positioning slot 9 for engaging the spring sheet 7 is provided on the inner wall of the assembly cylinder 3. There are multiple positioning slots 9, and the multiple positioning slots 9 are annularly distributed in the assembly cylinder 3. The spring sheet 7 is used to provide elastic support for the insulating seat 4. The elastic engagement with any one of the positioning slots 9 can provide an elastic locking effect for the insulating seat 4. In this way, when the power plug 5 on the insulating seat 4 rotates relative to the assembly cylinder 3 on the shell 1, the rotation can be elastically locked. After the power plug 5 is plugged into the socket, the shell 1 can have a locked rotation effect.

[0031] like Figure 5 As shown, when one end of the coil head on the spring piece 7 rotates in the direction N, due to the external abutment, the coil head on the spring piece 7 will be contracted, making it easier for the coil head of the spring piece 7 to pop out from the positioning slot 9. When one end of the coil head on the spring piece 7 rotates in the direction M, due to the external abutment, the coil head on the spring piece 7 will be opened, making it more difficult for the coil head of the spring piece 7 to pop out from the positioning slot 9. Therefore, in order to balance the elastic limiting effect of the spring piece 7 in the positioning slot 9, a chamfered portion 10 is provided on one side of the positioning slot 9. When one end of the upper coil head of the spring piece 7 rotates in the direction M, the chamfered portion 10 cooperates with the opening of one end of the upper coil head of the spring piece 7, thereby facilitating the spring piece 7 to slide out of the positioning slot 9. When one end of the upper coil head of the spring piece 7 rotates in the direction N, the other side of the positioning slot 9 is a right angle, and the sliding out effect is limited, so that the spring piece 7 will not easily slide out of the positioning slot 9. Through the above design, the elastic clamping effect of the spring piece 7 in the positioning slot 9 is stable, and the sliding out effect is more balanced, and the overall use effect is better.

[0032] When the present invention is in use, when it is necessary to insert the power plug 5 into a socket of any brand, especially a multi-row socket, if other plug-ins are also inserted into the multi-row socket, in order to avoid position conflicts with other plug-ins due to the length of the shell 1, the power plug 5 can be manually held in position to rotate the shell 1 so that the shell 1 and the insulating seat 4 can rotate relative to each other. At this time, the collector ring 62 can be adaptively rotated, and at the same time, the end of the spring sheet 7 can slide in the assembly cylinder 3 and elastically snap into any positioning slot 9. After the horizontal orientation of the shell 1 to be adjusted meets the requirement of the shell 1 being inserted and swung, the power plug 5 can be inserted into the socket of the socket. Therefore, the rotational cooperation between the shell 1 and the insulating seat 4 with the power plug 5 is not affected by the plug-in layout of the multi-row socket and the length of the shell, and there is a technical problem of insufficient plug-in adaptability.

[0033] Compared with the power adapters with the same functions in the prior art, the power adapter of the present invention has a lower cost and is suitable for market promotion.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
