Abstract: The claimed invention provides an ultrasonic welding method, whereupon joint portions in which a copper foil portion and a twisted-wire electric cable are placed one upon the other in each groove of a resin casing, the grooves having a through-hole portion. In the through-hole portion, the copper foil portion and the twisted-wire electric cable are placed one upon the other. Welding is performed in a state in which the piled-up portion is sandwiched between a welding tip formed at an end of a welding head and an anvil. Thus, the joint portion between the copper foil portion and the twisted-wire electric cable invade and are invaded by a portion of the resin casing softened by welding heat. The joint portion is fastened not only by welding, but also by the solidified resin.

Abstract: Disclosed herein is a wire conductor for a harness, comprising a central portion which is formed of aramid fiber and a conductor portion formed by circularly compressing a stranded wire which is prepared by arranging copper strands around the central portion and braiding the same. The conductor portion has a conductor sectional area of 0.03 to 0.3 mm.sup.2.

Abstract: Strands of a copper alloy containing 0.2 to 10 percent by weight of Sn are braided to form a stranded wire for a wire conductor for a harness having a conductor sectional area of 0.03 to 0.3 mm.sup.2. After the braiding, preferably stranded wire is heat treated so that its tensile strength is maintained at a prescribed level. The wire conductor for a harness has a breaking strength which is equivalent to that of a conventional harness wire, and is hardly broken by an impact. The wire conductor maintains its straightness, and strand ends do not fray upon cutting.

Abstract: There is disclosed a fitting-type connection terminal in which an insertion force for a terminal can be reduced while maintaining a stable contact resistance. If the thickness of a tin film on one of male and female terminals is 0.1 &mgr;m to 0.3 &mgr;m while the thickness of a tin film on the other terminal is not less than 0.1 &mgr;m, the hardness of the terminal is increasingly influenced by the hardness of a base material (of copper or copper alloy) with the decrease of the thickness of the tin film, so that the apparent hardness of the terminal increases. As a result, the adhesion of the tin film is suppressed, and the terminal insertion force can be reduced at least by more than 10% as compared with a reference value (1.0 &mgr;m for each of the male and female terminals). Particularly if the thickness of the tin film on the male terminal 10 is 0.1 &mgr;m while the thickness of the tin film on the female terminal 20 is 0.3 &mgr;m to 1.0 &mgr;m, the insertion force can be reduced by more than 30%.

Abstract translation: 公开了一种装配型连接端子，其中可以在保持稳定的接触电阻的同时减小端子的插入力。 如果阳端子和母端子之间的锡膜的厚度为0.1μm至0.3μm，而另一端子上的锡膜的厚度不小于0.1μm，则端子的硬度越来越受硬度的影响 铜或铜合金的基体材料，随着锡膜厚度的减小，端子的表观硬度增加。 结果，抑制了锡膜的粘合，并且与基准值（每个阳，阴端子为1.0μm）相比，端子插入力可以至少降低10％以上。 特别是如果阳端子10上的锡膜的厚度为0.1μm，而母端子20上的锡膜的厚度为0.3μm〜1.0μm，则插入力可以降低30％以上。
