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.
Claims3
An electric power plug comprising:
- a pair of elongated blades with each blade having at least one engaging means formed in a long side of the blade adjacent to one end of the blade for engaging with a blade retaining member;
- a blade retaining member made of an electrically insulating material and having a pair of blade engaging portions, each blade engaging portion comprising an outer tongue attached at one end to the blade retaining member and extending perpendicularly to the longitudinal direction of the blade retaining member, said outer tongue defining a slit between an inner side thereof and an opposing side of the blade retaining member, said slit opening to a longer side of the blade retaining member and having a width substantially equal to the thickness of the blade, said engaging portions engaging said engaging means of said pair of blades respectively to retain said blades relative to said blade retaining member;
- a cord having a pair of conductors, end portions of said conductors being connected to end portions of said pair of blades respectively;
- and
- a plug body made of a resin material with said blade retaining member and portions of said pair of blades in the vicinity of said blade retaining member including the end portions of the blades connected to said cord and said end portions of said conductors embedded in said plug body.
