Protective electrochemical cell package

Abstract

The invention pertains to housings and enclosures for assemblies of electrochemical cells such as used in consumer electronic devices. A system of structural elements having constant cross-section along at least one axis is provided to construct protective housings for electrochemical cell assemblies. Where cell assemblies include sensitive circuit elements such as circuit boards the fabricated housings include cover portions to reduce the chance of impact or contact damage to the circuit elements. By designing structural elements having open and constant cross-sections, a family of housing components may be fabricated from a single structural element by altering a length. Different configuration housings may also be constructed by rearranging the housing components or introducing additional interconnecting components. By incorporating a unified interconnecting element into each component, interchangeability is increased. In this way, the number of distinct housings that can be constructed from a limited number of distinct structural elements is increased. The invention includes cell assemblies incorporating such housing components. The invention provides inexpensive and easy methods of forming enclosures for a variety of cell assemblies by avoiding multiple toolings for unique parts.
