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 bottom portions of the sidewalls. When the electrical contact is in the channel, the tongue-like member urges the electrical contact upward against the bottom portions of the sidewalls it snaps behind the rim with an audible click and securely locks the electrical contact into place in the channel.
