Portable power supply adapters

Abstract

The invention discloses a portable power adapter which has small occupied space, aesthetic and harmonic appearance, and convenient deploying and collecting and carrying. The invention comprises a housing, a power input and an output line (51, 53), a power convention circuit (6), and a wire lock-up mechanism; the center of the housing is provided with a hollow stepped shaft column (2), the external sidewall of the shaft column (2) is provided with a ring diaphragm (22), an upper and a lower rotating disc (31, 32) is provided above and below the ring diaphragm (22), the stepped column surface of the upper and the lower rotating discs are respectively provided with external conducting layers (301, 302), the shaft column (2) is provided with an inner conducing layers (201, 202), the power input and the output lines (51, 53) are connected with the external conducting layers (301, 302) respectively, the input and the output ends of the power convention circuit (6) are connected with the inner conducting layers (201, 202), an upper and a lower twisting spring (41, 42) are connected between the upper and the lower rotating discs (31, 32) and the shaft column (2), and the power input and the output lines (51, 53) are wound the periphery of the upper and the lower rotating discs (31, 32).

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...

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.
