Abstract

With the continuing decrease in the size of pagers, the utilization of all exterior area is becoming increas- ingly critical. This trend, as well as the "Design for Assem- bly" inspired practice of reducing part counts, has focused designers attention on combining the functionality of mul- tiple parts into a single part.

DUAL FUNCTION CONTACT COVER

by Henry Wandt and Charles A. Actor

  With the continuing decrease in the size of pagers, the utilization of all exterior area is becoming increas- ingly critical. This trend, as well as the "Design for Assem- bly" inspired practice of reducing part counts, has focused designers attention on combining the functionality of mul- tiple parts into a single part.

  The invention illustrated in the following figures pro- vides a method to combine the functions of a battery door lock and a programming contact seal. This design eliminates the need to have a separate contact seal and conserves exterior area by locating the contacts under

the battery door lock.

  Figure 1 shows a top view of the lock in the closed position. In this position the contacts are not exposed. Figure 2 shows the lock in the open position which allows access to the contacts through the holes in the lock. Fig- ure 3 is a cross-sectional view of the lock and pager backcover in the closed position. Figure 4 is a cross- sectional view ofthe lock, pager backcover, and the pro- gramming contacts which illustrates the relationship between the parts during the programming operation.
