Abstract

A conductive terminal electrically connects a conductor of a conductive wire to a circuit board. The conductive terminal includes a body, a clamping portion having a pair of clamping arms, and a solder portion having a pair of solder lugs. The body has an opening through which the conductive wire is inserted and a passage communicating with the opening, the passage receiving the conductive wire and extending perpendicular to a surface of the circuit board. The pair of clamping arms extend from the opening towards the circuit board and obliquely towards each other so as to clamp the conductor of the conductive wire inserted through the opening. The solder portion has a pair of solder lugs extending perpendicular to a lengthwise direction of the passage and soldered to a pair of solder pads on the circuit board.
