Abstract

This is an area array connector adapted to make an electrical connection between a printed circuit board and a mating electrical member. The connector arrangement comprises a printed circuit board 1 having an attached connector block 2. The connector block 2 has a plurality of apertures with each containing a connector spring 3. The connector springs 3 each have a projection 3a which passes through plated-through-holes in the printed circuit board 1.

Area Array Connector

This is an area array connector adapted to make an electrical connection between a printed circuit board and a mating electrical member. The connector arrangement comprises a printed circuit board 1 having an attached connector block 2. The connector block 2 has a plurality of apertures with each containing a connector spring 3. The connector springs 3 each have a projection 3a which passes through plated-through-holes in the printed circuit board 1.

The mating member 4 may be a printed circuit card, a pluggable module, a connector cable, or like device. The mating member 4 has a plurality of projecting connector pins 5. To make an electrical connection, the member 4 is positioned over the connector block 2, and the projecting pins 5 are then loosely inserted into the apertures in the connector block 2 and into the enlarged U- shaped portion of the spring. An actuator 6 is operated to engage the member 4 and forceably move it in a direction parallel to the printed circuit board. Thus the projecting pins 5 are forced between the converging prongs 3C of the connector springs 3. This establishes the electrical connection between the projecting pins and connector springs.

This area array connector has zero insertion force, zero retention force and a low impedance electrical path.
