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： Provided is a terminal fitting capable of reliably press-bonding a core wire made of aluminum or aluminum alloy. A terminal fitting 3 is made of copper or copper alloy and includes: a bottom wall 34 which is overlapped with a core wire 41 made of aluminum or aluminum alloy; and a pair of crimping pieces 35 which is upright from each corresponding end portion of the bottom wall 34 and is bent inward so that a front end 35a faces the bottom wall 34 and the pair of crimping pieces is press-bonded to the core wire 41. The pair of crimping pieces 35 is bent so that outer surfaces 35b are tightly overlapped with each other, and has a pair of intermeshing portions 38 respectively formed in the outer surfaces 35b in the length direction of the core wire 41 to mesh with each other.

摘要： An aluminum (Al) terminal has a first bottom wall, and a pair of caulking pieces that are stood from the first bottom wall and caulked in a state where the first bottom wall covers a wire connection portion with the core wires arranged on the upper side from the underside. Thereby, the Al terminal made of Al or Al alloy can be crimped from outside the terminal fitting main body made of copper or copper alloy, and the spring back of the terminal fitting main body made of copper or copper alloy can be suppressed by the Al terminal.

摘要： A metal terminal includes a base plate portion for placing an electric wire thereon and a pair of crimping piece portions which extend upwardly respectively from opposite side edges of the base plate portion for press-contacting the electric wire. Each of the crimping piece portions has a distal end portion and a body portion such that a thickness of the each of crimping piece portions is tapered toward a distal end surface of the distal end portion from the body portion. A thickness of a distal end of the distal end portion relative to a board thickness T of the body portion of the each of crimping piece portions is not smaller than ⅕T and is less than ½T. An exterior angle of an angle formed by the distal end surface of the distal end portion and a tapered surface of the distal end portion is 60° to 30°.
