Abstract

PURPOSE:To provide a connector with which a predetermined insertion/ pull force can be given in spite of a thin plate thickness, and of which insertion/pull force is not reduced even in usage under a high temperature by welding a thin plate of a rectangular form of a specified alloy with a thin plate belt material, and bending an obtained matter to form an insertion/pull part. CONSTITUTION:A belt material 10 comprising a thin plate belt material 8 comprising a tape 6 of Au or Ag or its alloy cladded with a tape 7 of Cu or Cu alloy, and a thin plate 9 of Fe alloy welded with it at right and left side edges at the front part by an electron beam or laser is cut in a predetermined length. The back parts of the thin plate 9 on the right and left side of the cut belt material 10 are then cut and eliminated, and residual rectangular thin plates 9' at the front part are bent in the form of a U-letter on the upper surface side of the thin plate belt material 8 to form insertion/pull parts 11. For a connector thus composed a predetermined insertion/ pull force can be provided at the insertion/pull parts 11 if the plate thickness is thin when it is used for an automotive connector terminal, stable connection can be achieved, and the insertion/pull force is not deteriorated even in usage under a high temperature, thereby the connection can be stabilized.

When the thin strip material 1 made of u alloy is cut to a required length and then the left and right sides are bent in a U-shape toward the center of the upper surface to form the insertion / removal portion 5, a required insertion / removal force is applied to the insertion / removal portion 5. In order to achieve this, the plate thickness of the thin strip material 1 must be made thicker than necessary, and since the Cu alloy of the thin strip material 1 has low high-temperature characteristics, the insertion / extraction force decreases and loosens when used at high temperatures. The connection as was unstable.

Since the insertion / extraction part is formed by bending a U-shaped rectangular thin plate of Fe alloy on the upper surface side of the thin strip material, the insertion / extraction part has a strong elastic force and is superior to the conventional insertion / extraction part made of Cu alloy. However, even if the plate thickness is thin, the required insertion / removal force can be obtained as a connector terminal for automobiles and stable connection can be achieved. Further, since the insertion / removal portion is excellent in relaxation of thermal stress, the insertion / removal force does not decrease even if it is used at high temperature, it does not loosen, and the connection is stable. Furthermore, since the current carrying member, which is a thin strip material in which Au, Ag or their alloys and Cu or Cu alloy are clad, is provided at the center of the insertion / removal portion, the current can be conducted without any trouble.
