Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
109 words
Apparatus for providing an electrical connection between a display device of an electronic timepiece and a circuit controlling the display device, said apparatus comprising: A. a printed circuit board including a support member therefor, B. an insulating mounting member comprising a bore, C. a solid metallic stud carried by the circuit board support member including a pointed protrusion on the axial face of the stud, the stud positioned in the bore, D. a plug of electrically conductive elastomeric material arranged within said bore, and E. said protrusion of the metallic stud being constructed and adapted to engage said elastomeric plug, whereby good electric contact is assured without significant pressure.
