BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a coupling structure of an electronic apparatus and an electronic apparatus.

As the demand of consumers changes due to the high performance of digitalization of electronic products, market demand is changing due to the development of power supply devices with high capacity due to thinness and light weight and high energy density.

Power supply devices such as lithium ion secondary batteries, lithium ion polymer batteries, supercapacitors (electric double layer capacitors), and water capacitors with high energy density and large capacity have been developed in order to meet consumer needs.

In recent years, demand for mobile electronic devices such as portable telephones, notebooks, and digital cameras is continuously increasing. Especially, attention is focused on flexible mobile electronic devices including rolled type displays, flexible electronic paper, flexible liquid crystal display devices, and flexible organic light emitting diodes This has recently increased. Accordingly, a power supply for a flexible mobile electronic device should also be required to have flexible characteristics.

Specifically, a watch-phone that combines the functions of a mobile phone into a form of a wristwatch, especially flexible mobile electronic devices, has appeared, and a flexible power supply unit has been incorporated into the watchband of a watch phone.

However, when a flexible power supply device is used as a watch strap, there is a problem in that it is not easy to make electrical contact with the main body of the watch phone at the same time because of flexibility of the terminal of the flexible power supply device.
