Description

  The present invention relates to a cord for supplying power from a power source or transmitting a signal to an electronic device such as a portable personal computer.

  For example, in an electronic device such as a portable personal computer, an alternating current supplied from an alternating current power supply via an AC adapter is converted into a direct current, and electric power is supplied.

  An AC adapter used in this type of electronic device is electrically connected to an AC power source via a power cord when a relatively large distance between the power source and the electronic device is ensured. Thus, the power cord used with the AC adapter is provided with a cord member for supplying current, a power connector provided at one end of the cord member and connected to an AC power source, and the other end of the cord member. And a plug that is detachably attached to the jack on the AC adapter side.

  An electronic device such as a portable personal computer may carry an AC adapter and a power cord in preparation for long-time use, for example, on the go. Generally, when carrying without using a power cord, the power cord cord members are folded and bundled to prevent the power cord from becoming entangled or bulky, and the folded portion of the cord member is bound to a binding band. The method of binding with is known.

Further, when carrying the power cord, as a configuration for bundling a plurality of portions of the cord member in an folded state, there are an engaging concave portion and an engaging convex portion that are engaged with each other at opposite positions of the folded cord member. The provided structure is disclosed (for example, refer patent document 1). In this conventional power cord, it is possible to bind the cord member in a folded state by engaging engagement concave portions and engagement convex portions provided at a plurality of locations of the cord member.
