An insulating sheath for preinsulated ferrule type electrical connectors having the sheath partially surrounding the ferrule is disclosed. The sheath is a two layer laminate comprised of a layer of heat resistant polyamide bonded to a layer of tetrafluoroethylene film. The polyamide layer is against the ferrule with the tetrafluoroethylene layer being the outside of the sheath. When the connector is crimped onto wires, the polyamide layer and connector are encased by the tetrafluoroethylene layer. The connector insulated with the laminate has a minimum Limiting Oxygen Index value of 28.

Flame retardant preinsulated electrical connector

The multiple interconnection module of the present invention is adapted to conductively interconnect the substantially aligned conductive terminals of a pair of circuit devices and consists of a wiring support body formed of a resilient material and a sheet of flexible material secured to the outer surface of the support body. The flexible sheet has a plurality of paired contacts formed thereon in predetermined positions, with wiring strips electrically connecting each pair of contacts. These contacts are exposed on the outer surface of the sheet for engagement with the conductive terminals of the circuit devices and the resilient support body biases the contacts into proper engagement with the conductive terminals.

Interconnection of oppositely disposed circuit devices

A process for preparation of an activated or sensitized polyimide polymer, deposition of various catalysts on the sensitized polymer and subsequent plating on said sensitized and catalyzed surface of a metal, e. g., nickel, cobalt, copper, or gold from an electroless bath; improved adhesion, avoidance of blistering, etc. are observed; the process is capable of producing useful printed circuits such as for mounting integrated circuit chips.
