Abstract

An elastic sheet structure for the contact of a battery set used in a portable computer is provided. It comprises a positive-end elastic sheet and a negative-end elastic sheet having a central hole thereon. The size of the positive-end elastic sheet is smaller than that of the central hole of the negative-end elastic sheet. This invention may assemble several electric cells into a complete battery set for a portable computer. The special design avoids damaging the portable computer due to the misplacement of the positive end and the negative end of the electric cells of the battery set. It also provides a simple and convenient way to assemble the battery set.

Claims

1. A elastic-sheet structure for the contact of a battery set used in a portable computer comprising:

a positive-end elastic sheet; and

a negative-end elastic sheet having a central hole thereon, the size of said positive-end elastic sheet being smaller than that of said central hole of said negative-end elastic sheet;

wherein said battery set has a plurality of electric cells therein, each electric cell having a positive end and a negative end.

2. The elastic sheet structure for the contact of a battery set used in a portable computer as claimed in claim 1, wherein said positive-end elastic sheet connects to the positive end of one of said electric cells in said battery set while said negative-end elastic sheet connects to the negative-end of another one of said electric cells in said battery set.
