摘要： A copper alloy for use in an electrical and electronic parts contains Fe of 1.8-2.0 weight %, P of 0.025-0.040 weight %, Zn of 1.7-1.9 weight %, Sn of 0.40-1.0 weight %, and Ca of 0.0001-0.01 weight %, the balance being Cu and inevitable impurities. Further the copper alloy may contain one kind or two kinds of the elements selected from the group of Cr of 0.001-0.01 weight % and Mg of 0.001-0.01 weight %, by 0.001-0.01 weight % at a total amount. This copper alloy for use in electrical and electronic parts can dissolve the prior problem that cracking is apt to occur on the ingot during heating on the hot working process or during hot working, and can prevent a short-circuit due to the migration phenomenon of copper which is apt to occur with the high density integration of the electrical and electronic parts made of copper alloy, and further can improve the tool service life (wear resistance) of the die and can decrease the producing cost thereof.

摘要： A terminal crimping apparatus includes an anvil for supporting a metal terminal including a base plate portion for placing an electric wire thereon and a pair of crimping piece portions extending upwardly respectively from opposite side edges of the base plate portion and a crimper which includes a press-deforming portion having a generally arch-shape formed of two arc-shaped surfaces which are opposed to the anvil. The anvil and the crimper cooperate to press the crimping piece portions for crimping the crimping piece portions to the electric wire placed on the metal terminal. The shape of the crimper satisfies a formula, Index a=c·cos θ, where c represents a length of the arc-shaped surface of the crimper, and θ represents an angle formed by a tangential line to the arc-shaped surface at a central portion of the crimper and a vertical line.

摘要： A charging connector for an electric vehicle for charging a power receiving connector coupled with a power supplying connector on a charging stand includes air purging unit provided within the power supplying connector on the side to be coupled with the power receiving connector. The air purging unit serves to purge foreign substance such as dust or moisture applied. The air purging unit of the charging connector prevents moisture or foreign substance from intruding into the inside of the supplying connector to be coupled with the power receiving connector, and if intruded, permits them to be removed swiftly, thereby preventing troubles such as poor contact of terminal and short-circuiting.

摘要： In a charging connector for an electric vehicle for charging a power receiving connector coupled with a power supplying connector, the power supplying connector includes an outer housing to be coupled with said power receiving connector; an inner housing to be slidably mounted on the front half and housing a plurality of terminals; and an air cylinder mounted inside said outer housing inside the rear half of said outer housing and a piston connected to the rear end of said inner housing. Whereby the inner housing is driven toward said power receiving connector by the operation of said air cylinder so that said terminals are connected to corresponding terminals of said power receiving connector. In such a configuration, since the advancing drive of an inner housing in which terminals are housed is carried out using the air cylinder, a small number of components can be used and the piston has only to be connected to the rear end of the inner housing, thus simplifying the production cost and reducing the production cost.
