Abstract

The smaller size of today's pagers also reduces their weight proportionately. Traditional charger and progmm- mer devices have always relied on gravity to provide suffkient resistance force to spring loaded z-axis inter- connect pins that access electrical contacts on the bot- tom of the pager housing. The number of these interconnect pins has increased as more products utilize these pins for hmctions other than charging only (B+ and GND). Data transmission and external antenna porting through these contacts is also now common. Typical pagers now weigh less than 95 grams. Dividing this weight among three or more pins puts the force per pin at an unacceptably low level, less than the recom- mended loo-125 gram minimum for low current, point contact connectors. This device provides a means to lock a pager into the housing so that contact forces can be increased. Other methods of locking a unit into a charger require two handed operation to remove the pager since one hand is required to push back a latch while the other removes the pager. This device allows one handed oper- ation to remove the pager.
