The power cords of the existing power adapters are all connected outside the main part of the adapter. Because the power cords are long, they tend to become messy and inconvenient when storing and carrying them. Especially in some miniaturized products, the adapter part The space occupied is often close to or even exceeds the space occupied by these products. For example, the notebook computer is now smaller and smaller, and it is very convenient to carry, but its corresponding power adapter is still the same as before, or just put the main body of the adapter The size is reduced, but the power cord and its connection method have not changed. When storing and carrying, the power adapter takes up a lot of space, which makes it inconvenient to use. In addition, the appearance of the power adapter and the computer itself is also uncoordinated.

Embodiment 1
[0023] Such as figure 1 , figure 2As shown, the present invention includes a housing, a power input wire 51, a power input plug 52, a power output wire 53, a power output plug 54, a power conversion circuit 6, and a wire locking mechanism. The housing includes side walls 11, upper and lower ends Cover 12, two plug bins 14, 15 are arranged on the housing, the power input plug 52 and the power output plug 54 are respectively placed in the plug bins 14, 15, and the center of the housing is provided with There is a fixed hollow shaft 2, the power conversion circuit 6 is located in the hollow of the shaft 2, the shaft 2 is an axially symmetrical stepped shaft, and the side wall of the shaft 2 is outside the shaft The axial center of the shaft column 2 is provided with an annular partition 22, the top of the annular partition 22 is provided with an upper turntable 31, and the bottom is provided with a lower turntable 32, and the outer circumference of the upper turntable 31 and th...
Embodiment 2
[0025] Such as image 3 , Figure 4 , Figure 5 , Image 6 As shown, the difference between the present embodiment and the first embodiment lies in: the wire locking mechanism and the connection structure between the outer conductive layers 301 , 302 and the inner conductive layers 201 , 202 are different. The wire locking mechanism in this embodiment includes a pressing piece 82, a pressing piece 83, and a compression spring 84. One end of the compression spring 84 is connected to the positioning part 112 on the housing, and the other end is connected to the pressing piece. 82 is connected to the upper part, and the lower part of the pressing part 82 is rotatably connected to the fixed shaft 113 located on the housing. The bottom of the pressing part 82 is provided with a hook 824 and a guide groove 825. The pressing part 83 is provided with a shaft portion 831, a perforation portion 832, and a crimping portion 833, the hook 824 passes through the perforation portion 832 a...

Description
technical field [0001] The invention relates to a portable power adapter. Background technique [0002] At present, power adapters are widely used in electronic products, household appliances, notebook computers and other products to obtain the rated voltage and current required for the product to work. The power cords of the existing power adapters are all connected outside the main part of the adapter. Because the power cords are long, they tend to become messy and inconvenient when storing and carrying them. Especially in some miniaturized products, the adapter part The space occupied is often close to or even exceeds the space occupied by these products. For example, the notebook computer is now smaller and smaller, and it is very convenient to carry, but its corresponding power adapter is still the same as before, or just put the main body of the adapter The volume is reduced, but the power cord and its connection method are not changed. When retracting and carrying, t...
