Description of the Related Art A multi-tap having a large number of insertion holes for inserting projecting pieces of a male plug provided at the end of a cord of a home electric appliance, OA equipment, etc. has a male terminal at one end for connecting to an outlet provided on a wall surface. It has a case in which a large number of female plugs having a mold plug and having an insertion hole on the outer surface at multiple ends are arranged at predetermined intervals. When a large AC adapter or a large male plug is inserted into such a multi-tap insertion hole, the adjacent insertion hole is blocked and cannot be used. Therefore, a short electric cord having a male plug and a female plug may be used so that the adjacent insertion hole is not blocked. Further, when a large male plug was directly inserted into the insertion hole into the multi-tap, the tap sometimes fell due to the weight. In particular, when a multi-tap male plug was directly inserted into an outlet installed on the wall, and plugs were inserted into multiple insertion holes, the entire multi-tap became heavy, causing trouble such as falling out of the outlet. . Further, since the insertion hole of the female plug is exposed, dust and insects may enter the hole and cause a failure. Therefore, recently, tools for shielding these insertion holes are sold as a single item.
