  • Patent number: 5639265
    Abstract: An electrical connector wherein no clearance is produced between the bent terminal portion and the insertion portion, which in turn prevents the bent terminal portion from moving along the length of the electric connector. As a result, a distance .alpha. between adjacent bent terminal portions can be kept constant, thereby allowing a wiring pattern of a wiring board on which the electric connector is placed to coincide with the bent terminal portions, increasing the soldering area, and hence improving the strength of soldering against the separation of soldered parts.
