Background technique

Power adapters (Adapters) have been widely used to convert commercial power into another voltage for use by electronic devices. For example, a notebook computer is usually equipped with a power adapter. Existing power adapters usually have at least one end of a power cord connected to the electronic device, and then use the plug provided on the power adapter body to connect to the mains, or use another power cord to connect to the mains.

Please refer to FIG. 2 and FIG. 3 , which are perspective views of the unfolded line mechanism of the utility model. The whole line mechanism of the present utility model is to utilize the space formed after the outer retaining cover 20 is pulled out. The outer cover 20 has a connecting portion 22 disposed in the housing 10 so as to be movable outward. In this embodiment, the connecting portion 22 of the outer cover 20 passes through the half shell 12 of the outer cover 20 . When the outer cover 20 moves outward, a space 201 is formed between the outer cover 20 and the casing 10 ; the connecting portion 22 is still connected to the casing 10 . At this time, the power cord 30 is optionally wound around the connecting portion 22 in a circular shape and rolled between the outer cover 20 and the casing 10 . As shown in FIG. 3 , it is shown that the power line 30 is being wound in the line space 201 . The line space 201 in this embodiment is flat, but not limited thereto. the

In addition, the position of the notch 1232 allows the user to hold the outer cover 20 with fingers, so that it is more convenient to move the outer cover 20 outward. the

When the outer cover 20 of the present utility model is pulled open, the space for the whole line is provided. In other words, when the power supply device supplies power to the electronic device at ordinary times, the wiring mechanism can be hidden. Compared with the existing whole line mechanism fixed outside the power supply device, the utility model does not affect the appearance of the power supply device and does not cause inconvenience to users. the

Please refer to FIG. 4 , after the power cord 30 of this embodiment is wound, the outer cover 20 is blocked and located outside the casing 10 . At this time, the volume of the power supply device after the whole line is only increased by about 30 widths of the power line, which does not affect the convenience of storage. 4, the utility model can estimate how the power cord 30 is completely accommodated in the whole line space 201, assuming that the cross-sectional area of the power cord 30 is Acable; the length of the power cord 30 is Lcable; the area of the outer cover 20 is Acover; The width of the line space 201 is W; its formula is:

Acover×W is greater than or equal to Acable×Lcable;

To accommodate longer power cords, if necessary, the width of the entire line space 201 can be increased, for example, one and a half times or twice the width of the power cord 30. the

Referring to FIG. 5 , the structure of the connecting portion 22 will be described in detail. Fig. 5 is a cross-sectional view of a power supply device with a line-integrating mechanism of the present invention. Based on the above design considerations, the length of the connecting portion 22 may be slightly greater than the diameter of the power cord 30 .

The barb 221 can be elastically connected to the outer cover 20 , as shown in FIG. 5 , the connecting portion 22 includes two elastic plate-shaped elements, and the barbs 221 are respectively formed on free ends of the elastic plate-shaped elements. When assembling the outer cover 20 on the casing 10 , it is only necessary to press the elastic plate-shaped elements to make the barbs 221 enter the assembly hole 120 . The number of the above-mentioned elastic plate-shaped elements may be multiple. the

Based on the above description, the length of the connecting portion 22 in this embodiment is substantially equal to the diameter of the power cord 30 plus the length of the barb 221 . The overall volume of the whole line mechanism occupied by the power supply device is approximately equal to the volume of the barb 221 , and only some extra volume is needed for accommodating the partial connecting portion 22 . The barbs 221 can even be arranged in gaps between internal components of the housing 10 . the
