An electrical connector including a top clamp plate, two circuit bars, a resilient pressure pad, a bottom clamp plate, and means for fastening two flexible circuits and a third circuit device in mating electrical contact therein is disclosed. Each flexible circuit is mounted on and wrapped about a separate one of the circuit bars with an adhesive to provide a solidly backed sub-assembly. The top clamp plate is then fastened to the sub-assemblies with screws and retaining clips to create a single sub-assembly. The resilient pressure pad is mounted on the bottom clamp plate and the third circuit device is mounted thereon. Each circuit bar is then mounted over the third circuit device to make electrical contact between the third circuit device and each flexible circuit. The components are aligned using pins extending upward from the bottom clamp plate. The single sub-assembly is then fastened to the bottom clamp plate using screws to complete the assembly. In an alternative embodiment, a resilient connector pressure pad having wires extending through and protruding from the thickness thereof is used. The resilient connector pressure pad is located between the flexible circuits and the third circuit device, the wires protruding therefrom actually completing the electrical contact.

A method for preforming of two or more flexible cables in an arrangement consisting of a combination of rigid printed circuit boards and flexible cable sections extending therebetween. Moreover, also provided is an apparatus for the preforming of two or more flexible cable sections of a combination of rigid printed circuit boards and therewith interposed flexible cable sections which are adapted to interconnect the rigid printed circuit boards. The apparatus consists of a tool constituted of an elongated cylindrical member having a tapered leading end which narrows into an ultra-thin flat end section of a blade-like configuration, and which is adapted to be pushed between the flexible cables and so as to preform the flexible cable sections and cause them to yield in a predetermined outwardly bowed permanently relationship between the rigid printed circuit boards at the opposite ends thereof to lengthen the fatigue life of the conductors in the flexible cable sections.

An electrical connection of a transfer station releasably, repeatably electrically couples with respect to a matching connection of a portable cartridge. A substrate in the portable cartridge has electrical contacts on a facing surface. In the transfer station, a matching circuitized flexible substrate has electrical contacts on a facing surface thereof, which are arranged to match the portable cartridge electrical contacts when in a face-to-face relationship. An elastomeric compression element, at the rear of the matching substrate, has individual protruding compression members contacting the rear surface and registered with corresponding individual electrical contacts. Elongated electrical contacts are registered with two adjacent individual compression members. A loader engages the portable cartridge, registering the cartridge substrate contacts in face-to-face relation with the matching flexible substrate electrical contacts, and exerting a normal force to the cartridge to compress the compression element and create non-wiping contact between the facing electrical contacts.

A bonding opening exposing conductors through a cover of a multiconductor flat cable or electrical component to allow direct bonding thereof is described. The multiconductor flat cable or electrical component having a base layer with conductors disposed thereon and a flat cover having an opening provided therein at a bonding site, preferably by die cutting. The flat cover with the opening is laminated to the base layer, overlaying the conductors, so that the conductors are mechanically stabilized by the base layer while being exposed through the bonding opening. The shape of the multiconductor flat cable or electrical component of the present invention may be highly varied. In one embodiment, the flat multiconductor electrical component circumferentially extends around a central area, for example, totally encompassing in IC chip which may be connected to the conductors thereof at a bonding site. The conductors fan out from the IC chip to connections at the outer perimeter, and the top cover is eliminated completely.
