ABSTRACT:
A zero insertion force electrical connector for use with a device having an array of pin terminals including a lower connector housing having a top surface and a plurality of cavities in the top surface corresponding to the array of pin terminals. Each of the cavities includes a base wall spaced from the top surface. A plurality of resilient terminals are mounted in the cavities. Each of the terminals includes a mounting portion for securing the terminal in the base wall, a free end portion, a contact structure adjacent the free end portion and a spring arm portion between the base wall and the contact structure. The pin terminals are moved in the cavities in a first direction along a path of travel between an unmated position wherein the pins are spaced from the contact structures in the cavities and a mated position wherein the pins are fully mated with the contact structures. The contact structure includes a pin engagement surface at least partly inclined with respect to the path of travel. The spring arm portion of each of the terminals is a generally flat and planar leaf region oriented generally parallel to the first direction. The leaf region includes a first side edge at a side of the terminal where the pin first engages the contact structure and a second side edge extending from the mounting portion to the contact structure at the opposite side of the terminal. Notch means is provided in at least one of the side edges for increasing the flexibility of the leaf portion.
