US 4,734,044 A · Connectors for use with piezoelectric polymeric film transducers

Abstract

Piezoelectric polymer film transducers include a metallized film electrode deposited on each of the two surfaces of the film. The electrodes are provided with leads extending therefrom in staggered parallel relationship. Each lead of the improved connector is associated with a reinforced assembly comprising plastic strips, a terminal connector, optional spacer washers, and a metal rivet penetrating the assembly such that electrical contact is effected between the lead and terminal connector. To insure positive electrical contact, a conductive ink may be deposited on one of the plastic strips through which an orifice is provided. The orifice communicates with a selected lead. The ink coats walls of the orifice to insure electrical continuity between the lead and terminal connector. A modified connector assembly disposes the reinforced connectors beyond the edges of a substrate which carries or supports the piezoelectric polymer film transducers.

Dependent claims

An improved connector for use with piezoelectric polymer film transducers adhered to a substrate comprising

a film of piezoelectric polymer,
a metallized film coating electrode provided on each face of said film in substantially superposed relationship, each of said electrodes having a lead extending substantially to an edge of said substrate in staggered parallel relationship, said upper lead and said lower lead each having a plastic strip adhered thereon, said plastic strips extending beyond edge of said substrate,
aligned passageway means disposed through said plastic strips which extend beyond said substrate,
rivet means disposed through each of said aligned passageway means,
electrical terminal means contacting each of said rivet means to form a pair of secured adjacent connector assemblies beyond edge of said substrate,
one of said plastic strips having an orifice disposed therethrough communicating with one of said leads,
a conductive ink deposited over said one of said plastic strips and said orifice and contacting said rivet means associated therewith,
said ink at least coating walls of said orifice forming good electrical contact between said one of said leads and said electrical terminal means associated therewith.
