ABSTRACT:
An electrical receptacle terminal comprises a wire connection section, a rectangular body section and a pair of cantilever beam contacts extending therefrom. Insertion of a male tab between the cantilever beams initially prises the beams resiliently apart whilst passing first protrusions at a forward end of the terminal, and then further biases apart the cantilever beams when inserted between second contact dimples axially rearwards of the first protrusions. Electrical contact is finally made between the contact dimples and the male tab, which due to the short lever arm and the point contact, has a high contact pressure thereby ensuring good electrical conductivity therebetween. Certain applications may require lower currents, and the insertion force can be further reduced by providing cutouts in the terminal body section to make the resilient cantilever beams more supple. The latter can be done without designing new connector housings or a new terminal, and requires only a small change in the stamping process, which provides for a cost-effective solution.
