Abstract

An electrical contact limiter structure of wire connection terminal has a simplified structure and is easy to operate to enhance the stability of the operation and motion of a metal leaf spring. The wire connection terminal includes conductive components mounted in the insulation case and electrical contact assembled with the conductive components. The electrical contact has a limiter for receiving the metal leaf spring and restricting moving path thereof. The limiter is partitioned into at least one space. A limitation mechanism is assembled with the limiter. The metal leaf spring is mounted in the space. The wiring circuits or conductive wires coming from an apparatus can be easily directly plugged into the space of the limiter to insert with the metal leaf spring. The limiter and the limitation mechanism cooperatively prevent the metal leaf spring from being deflected and over-bent and damaged in operation.
