Abstract
A connection portion of a contact for use in an electrical connector or the like. The connection portion is in the form of a substantially U-shaped groove, to which is connected an exposed conductor of an electric wire. The connection portion includes on both sides bending pieces forming the walls of the U-shaped groove and asymmetrically arranged. With this construction, a relatively deep and wide groove of the connection portion is obtained even if the contact itself is small.
Claims3
An electrical terminal having a connection portion of a deformable contact which is in a form of a substantially U-shaped groove defined by an interconnection of a pair of side walls between which is positioned an exposed conductor of an electric wire, wherein said side walls include bending portions above the U-shaped groove of the connection portion and are asymmetrically formed with respect to a longitudinal center line of said connection portion and wherein each of said bending portions are trapezoidal in shape, a shorter portion of the one trapezoidal bending portion is opposite to a longer base of the other trapezoidal bending portion at one end of the U-shaped groove and the shorter base of the other trapezoidal bending portion is opposite to the longer base of the other trapezoidal bending portion at the other end of the U-shaped groove, whereby to enhance a gripping function of the connection portion to the conductor by a diagonal grip line across the conductor.
A connection portion of a contact which is in a form of a substantially U-shaped groove within which is positioned an exposed conductor of an electric wire, and including deformable bending pieces defining the U-shaped groove of the connection portion which are asymmetrically formed and are deformed toward each other along a longitudinal axis of the contact to contain the conductor therebetween, and wherein each of said bending pieces forms a part of a rhomboid defining a U-shaped groove therebetween, and wherein each rhomboid portion includes a highest portion located at one end of the U-shaped groove, and the highest portion of the other rhombic portion is opposite to a lowest rhombic portion of the other bending piece, whereby to enhance a gripping function of the connection portion to the conductor by a diagonal grip line across the conductor.
