BATTERY HOLDERS WITHOUT CONVENTIONAL METAL CONTACTS

by Henry Wandt and Charles Actor

Global competition in battery powered devices has created a need to develop a low cost battery holder system which is designed for manufacturability and long term reliability.

   Two battery holder systems which meet these goals have been invented. Figure 1. illustrates the first system which consists of a nonwnducting battery holder and two wnductive elastomeric contact pads. In addition to wnstraining the battery, the battery holder also serves to position the contact pads so as to ensure electrical contact between the battery and the printed circuit board of the powered device.

   The second system, shown in Figure 2. consists of a single molded plastic battery holder with selectively plated contacts. The contacts complete an electrical circuit between the battery terminals and the printed circuit board of the device. The system may be either manually or robotically placed on the PCB and then soldered by any conventional method. No assembly or further processing is required.
