Portable power cord and power adapter

Abstract

The present disclosure provides a portable power cord and a power adapter, which include a plurality of segments of wires that are electrically connected in sequence. The inside of the wires is a wire wire, and the outside is covered with an elastic sheath. The two ends of each segment of wires are respectively provided with a rotating shaft and a shaft sleeve. The rotating shaft of the wire is rotatably matched with the shaft sleeve of another adjacent wire. The shaft is provided with a first contact, and the shaft sleeve is provided with a second contact. The first contact is used for docking with the second contact. It is used to make the metal wires of the wires at both ends corresponding to the rotating pair conduct; by configuring the traditional flexible wire structure as an elastic wire structure connected by multi-segment rotation, the wire has a certain degree of elasticity while forming a path, and only needs to be rotated during use. Just release the required length, and the unreleased part is still in a folded structure. The folded storage method avoids the winding of the wires, and can make the wires in a regular structure after storage, so that the power adapter as a whole meets the existing portable equipment needs.

Description

technical field [0001] The disclosure relates to the field of computer spare parts, in particular to a portable power cord and a power adapter. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Laptop computers and other portable electrical appliances are more and more widely used. They are small in appearance and thin in overall, which can realize mobile office. However, portable devices are also limited by their volume and mobility, and the internal batteries cannot be made too large, so It is necessary to configure a power adapter for timely charging. [0004] The inventor found that most of the current power adapters used for portable devices are fixed-length power cords, that is, the length of the wire connecting the adapter plug and the device connector is fixed. It is inconvenient to adjust the length of use, and when the power ad...

[0003] Laptop computers and other portable electrical appliances are more and more widely used. They are small in appearance and thin in overall, which can realize mobile office. However, portable devices are also limited by their volume and mobility, and the internal batteries cannot be made too large, so You need to configure the power adapter for timely charging

[0004] The inventor found that most of the current power adapters used for portable devices are fixed-length power cords, that is, the length of the wire connecting the adapter plug and the device connector is fixed. It is inconvenient to adjust the length of use, and when the power adapter and the portable device are put into the storage bag together, the wire needs to be wound several times before it can be put into the bag, which is inconvenient to store and carry; on the other hand, this winding method will cause the overall power adapter The irregular shape prevents the power adapter from being in uniform contact with the portable device. Once subjected to external impact or excessive thrust, the power adapter will generate concentrated stress on the portable device and damage the device; therefore, it is difficult to meet the requirements of the existing portable device for the power adapter. portable needs
