This disclosure is directed to a connector unit which has the capability of mating a plurality of side by side insulated conductors (usually in the form of a multiconductor, flat, flexible, bonded or laminated cable) with a plurality of similarly spaced contact pad areas on a printed circuit board (PCB). The multi-conductor cable is mated to the PCB in a quick-connect manner and enables also a quick-disconnect, or separation of the cable assembly, from the PCB, to be accomplished with one hand only, and with no tooling required. The resulting contact pressure between the PCB and the leads of the multi-conductor cable is above a certain predetermined minimum and is reproducible, even after repetitive quick-connect and disconnects of connector unit from the PCB. The mating of the connector unit to the PCB is accomplished with low insertion force. Further, the connector unit is capable of electrically engaging a PCB of varying thickness. The foregoing is accomplished by a precise pin-type alignment means between connector unit and the PCB in combination with an elongated spring clip affixed to the connector unit, which spring clip engages the PCB, under a predetermined contact pressure, after the pin-type alignment is achieved. Also, there may be provided, within the connector unit, and in combination with the cable assembly, a means for providing alternating ground lines between adjacent signal lines, to reduce cross-talk. The connector unit is provided with spring loaded electrical contact strips on the signal lines to assure uniform contact pressure with the contact areas of the PCB.
