Abstract

An electronic connector socket has an upper RJ-45 hole and a lower USB hole in which at least two USB sockets can be formed. When manufacturers mass-produce the electronic connector sockets, separately making USB socket modules is not necessary anymore. The time to manufacture the electronic connector sockets also can be reduced. The manufacturers are able to increase profit from making the electronic connector sockets.
