ABSTRACT:
A smoke/fire detector assembly having a base section and a removable sensor section. The base section includes a plurality of electrical contacts and the sensor section includes a corresponding plurality of electrical contacts. Each one of the sensor section electrical contacts includes a member having a first end, extending from the sensor section, and a second end electrically connected to electrical components within the sensor section. Each one of the base section electrical contacts has: a first section having a surface adapted for mounting to a surface of the base section; a second section, having an edge common with the first section and a surface extending perpendicular to the surface of the first section; and, a pair of finger-like members, extending from a second edge of the second section. The second edge of the second section is perpendicular to the common edge. The finger-like members are laterally spaced along, and cantilevered from, the second edge of the second section. The finger-like members extend along a common direction. Distal ends of the finger-like members are spaced from each other laterally in a direction perpendicular to the common direction to receive, and contact, opposing surfaces of the first end of the sensor electrical contact. The first section, second section, and pair of finger-like members are a stamped, single piece thereby reducing the number of pieces required in fabricating the base section of the smoke/fire detector assembly.
