摘要： An improvement in a light bulb socket in the form of a generally U-shaped removably mounted base member. The base member is adapted to fit in the bottom of the socket and includes a bight portion and two leg portions. The bight portion has a base contact mounted thereon and the two leg portions are resiliently movable toward each other. When the leg portions are pinched together, the base member is insertable into the socket. When the pinching force is removed from the leg portions the base member is force fit into the bottom of the socket.

摘要： Apparatus for securing an electrical connection box which houses a first electrical connector to a second electrical connector which has been plugged into the first connector includes at least one rod mounted in a respective bore formed in the connection box so as to be freely rotatable therein and wherein each rod has a first end which projects from the connection box having a head accessible for rotating the rod and a second end constituting a threaded stud adapted to be threadedly connected to a nut fixed to the second electrical connector. The rod is free to be axially displaced within the bore to a limited extent thereby permitting the electrical connection of the connectors to be made prior to securing the same to each other.
