Abstract
Abstract In an electrically energized timepiece, an anisotropically conductive elamer is fixed to the timepiece casing to provide a mechanical seal between the movement compartment and power cell. With slight pressure of the elastomer between the power cell and timepiece contacts, an electrical connection is made between the power cell and contacts, but the elastomer acts as an insulator along its surface between timepiece contacts.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
59 words
Power cell compartment for an electrically energized timepiece wherein an envelope formed from an anisotropically conductive elastomer partially encloses the power cell and is fixed to the timepiece casing so as to provide a mechanical seal between the movement compartment and the power cell compartment and to assure electrical connection between the movement contacts and the power cell electrodes.
Claim 2
Dependent Claim
59 words
Power cell compartment for an electrically energized timepiece wherein an envelope formed from an anisotropically conductive elastomer partially encloses the power cell and is fixed to the timepiece casing so as to provide a mechanical seal between the movement compartment and the power cell compartment and to assure electrical connection between the movement contacts and the power cell electrodes.
Claim 3
Dependent Claim
43 words
Power cell compartment as set forth in claim 1 wherein the envelope is a good conductor of electricity across its wall thickness and a good insulator along its surfaces in regions where the movement contacts and power cell electrodes are proximate one another.
Claim 4
Dependent Claim
24 words
Power cell compartment as set forth in claim 1 wherein the envelope is attached to the timepiece casing and is free of the movement.
Claim 5
Dependent Claim
38 words
Power cell compartment as set forth in claim 3 wherein a cover member is provided in the timepiece casing and is arranged and adapted to seal the power cell compartment and to permit access to the power cell.
