There was also a problem that the risk of disconnection of the connection site.

On the other hand, since the terminal insertion groove into which the plug terminal of the plug is inserted is always open in the recess of the outlet, when a conductive object is inserted into the terminal insertion groove due to curiosity, children may not only cause an electric shock, but also foreign substances in the terminal insertion groove. When inserting the plug there was a problem such that it is impossible to insert the plug terminal of the plug.

In addition, there was a problem that it is difficult to accurately insert and plug the plug into the outlet in the dark state, there was a problem in that it is a waste of economic aspects by continuously consuming standby current in the plug connected state.

Due to this, the terminal is built in non-exposure type to prevent the occurrence of short circuit or electric shock through improper connection, and it is possible to connect and dismantle easily and to cut off the power supply even when connected by the function of safety switch. There is an urgent need for an improved electrical connection device to prevent wasteful waste and to provide accurate connections even in the dark.
