ABSTRACT:
A contact element for electrically connecting a leadless circuit package to another circuit plate having a self-locking function of the circuit package. The contact element has a base portion to be fixedly connected to the circuit plate, a contact portion to be in press-contact with a pad of the circuit package, and an intermediate portion extending between the base portion and the contact portion. The intermediate portion extends upwardly from the base portion, is bent to extend downwardly, and is turned to extend in an inclined upward direction. The contact portion is formed at the extended end of the inclined portion. A protrusion is formed at the bent portion to project to the side of the contact portion. When the circuit package is pressedly adapted to a connector using the contact elements to engage the terminal pads with the contact portions, the upper edge of the circuit package engages with the protrusions, so that the circuit package can be prevented from falling off upwardly from the contact elements.
