Description

  The present invention is provided in a cable for connecting an electric vehicle and a charging outlet provided in the charging cabinet in an electric vehicle charging cabinet (hereinafter referred to as a charging cabinet) installed to charge the electric vehicle. The present invention relates to a structure for holding an earth leakage breaker relay storage box (hereinafter referred to as a protective device).

  In order to charge an electric vehicle, it is necessary to connect a vehicle-mounted battery and a charging outlet provided in the charging cabinet with a cable. And this cable is equipped with the protective device which has the earth-leakage interruption function for the purpose of protection of a human body. Since the protection device is often provided in the vicinity of a plug for plugging into a charging outlet, the protection device is hung from the connecting portion between the charging outlet and the plug during charging. Therefore, there is a problem that a load is applied to the plug from the charging outlet. Therefore, a charging cabinet as described in Patent Document 1 has been devised. That is, the above-described problem is solved by providing a holding member capable of holding the protective device in the cabinet body of the charging cabinet and holding the protective device on the holding member during charging or the like.
