Abstract
A smoke/fire detector assembly having a base section with electrical contacts and a removable/attachable sensor section having corresponding electrical contacts. Each one of the electrical contacts is adapted to electrically contact a corresponding one of the base section electrical contacts. Each one of the electrical contacts has a threaded hole formed therein to receive an electrical contact screw. The hole has a projecting rim disposed about a peripheral portion. The base section has a plurality of recessed pocket formed therein for a corresponding one of the plurality of base section electrical contacts. Each one of the pockets has a pair of opposing sidewalls, a platform, and a resilient tongue-like member protruding into a region between the opposing sidewalls. Upper surfaces of the platform and the tongue-like member are disposed in a common plane spaced from the bottom portions of the sidewalls to provide a channel therebetween. When engaged by a corresponding one of the electrical contacts, the tongue-like member is configured to depressed downward enabling side edge portions of the electrical contact to slide within the channel and to urge the contact upward against the …
