Abstract: An electric power plug comprises blades, a bridge and a plug body. The bridge includes sleeves for covering the roots of the blades and a core for holding the lower ends of the blades. The blades and the core are integrally molded. The plug body is molded so that the plug body embeds the bridge except the upper portions of the sleeves. The core may embed the lower portions of the blades, cords, a caulking portion for connecting the lower ends of blades and wire conductors of the cords. A cavity may be formed at the central portion of the core. The plug body may be molded so that the plug body embeds the bridge and the cords except the upper portions of the sleeves.

Abstract: An electric power strip with cell charging receptacle including a plurality of plug connecting portions located in a socket body and at least one secondary cell receiving portion located in an opening in an outer surface of the socket body for charging a secondary cell, the plug connecting portions and the cell receiving portions connected by a plurality of conductors for connection to a power source.

Abstract: An electric plug made of a synthetic resin material and capable of preventing tracking comprises a plug main body made of a synthetic resin material such as PVC, a pair of blades connected to electrical wires exposed at one end of a cable, and a groove formed in the front face portion of the plug main body at a position between the blades, so that the blades are prevented from becoming short-circuited due to the presence of dust or water-drops between the plug blades.

Abstract: The invention is directed to a power plug which has a high physical strength against traction forces tending to pull the blades out of the plug body. The power plug of the invention realizes the above characteristics by comprising a pair of blades, each of the blades having one end connected to a cord, and a blade retaining member. The blade retaining member is made of an electrically insulating material, and has retaining portions which retain the blades so that they are not displaced relative to the blade retaining member. A resin molded plug body embeds the blade retaining member, proximal end portions of the pair of blades at which the blades are connected to the cord, and an end portion of the cord to which the blades are connected.

Abstract: An apparatus is provided for cutting and holding a piece of wire cord. The apparatus comprises a conveyor which includes a plurality of plates for movement in a first direction and a plurality of holding blocks wherein each of the holding blocks is mounted on a corresponding one of the plates. Each of the holding blocks has a fixed portion and a slidable holder portion, the slidable holder portion being slidable relative to the fixed portion. An advancing device advances the cord a predetermined length in a direction perpendicular to the first direction, and a cutter is positioned downstream of the advancing device for cutting the wire cord into cut portions of the predetermined length.

Abstract: An apparatus is provided for performing an operation on a plurality of electrical cords with a pair of terminal blades attached to each cord. The apparatus comprises a plurality of carriers for receiving a plurality of electrical cords with a pair of terminal blades attached to each cord. Each of the carriers comprises a frame member having first and second sides opposed to each other. The first side has a plurality of pairs of recesses therein, each of the pairs of recesses receiving a pair of the terminal blades and securing members secure the terminal blades in the recesses. The second side has a plurality of cord inserting grooves, each of the grooves receiving one of the cords therein and a cord chuck retains the cord in the groove. The cord chuck is automatically operated. First, second, third and fourth side conveyors transport the carrier to various positions wherein manufacturing operations are performed at each of these positions.

Abstract: An apparatus is provided for rotating the terminal blade for a structure which comprises a pair of terminal blades attached to a wire cord. The apparatus comprises a support for supporting the terminal blades, the support including a recess having contact surfaces wherein the terminal blades contact the recess on the contact surfaces thereof. At least one blade rotating device is provided which has a projection extending therefrom. A drive moves the recess and the blade rotating device towards each other such that the projection is moved between the terminal blades and contacts one edge of each of the terminal blades. The opposing edges of the terminal blades contact the contact surfaces of the recess, thereby causing each terminal blade to rotate between the projection and the recess such that the pair of terminal blades are aligned and positioned in parallel planes.
