601103 A 16A socket 1 comprising a base 3, and a L-pole earth contact 3.2, a N-pole earth contact 3.1 and an E-pole earth contact 3.3 which are provided in the base 3 for connecting with a live wire, a neutral wire and a ground wire respectively. The 16A socket 1 further comprises a protection shutter 2 disposed in the base 3 for covering the N-pole earth contact 3.1 and the L-pole earth contact 3.2. The protection shutter 2 comprises a drive surface and a planar surface portion over the E-pole earth contact 3.3 which are joined together. The drive surface and the planar surface portion are formed such that when a 16A plug is inserted into the 16A socket 1 the E-pole plug pin of the 16A plug is brought into contact only with the drive surface but not with the planar surface portion, while when a 10A plug is inserted into the 16A socket 1 the E-pole plug pin of the 10A plug is brought into contact only with the planar surface portion but not with the drive surface.
