ABSTRACT:
A narrow-pitch flat cable connector for use in connection of flat cables to printed circuit boards or other substrates includes wireform or prestamped female contacts on the same narrow pitch as that of the cable conductors and a connector housing with contact-receiving slots on the same narrow pitch as that of the cable conductors. The female contacts have U-shaped forward portions and in one embodiment are mounted in staggered offset relationship to the printed circuit board to present contacts at the same narrow pitch established by the narrow pitch of the conductors in the cable. The cable is terminated with a connector housing having a lateral cable insertion channel and vertical pairs of contact-receiving slots communicating with the cable insertion channel and aligned with the conductors of the cable. In one embodiment, the contact-receiving slots have different depths depending on which side of the cable electrical contact is to be made, thereby permitting double-sided contact to the cable, with the different depths and the insertion channel configuration providing a shelf to the side of the cable opposite that to which electrical contact is made. In one embodiment, an insulation displacing connector stamping is utilized which removes insulation from the conductors of the cable to permit contact to the cable. In a further embodiment, a specialized U-shaped removable transverse strain relief member is provided.
