Abstract
A multiple squib assembly is provided for use in a chaff deployment system. A method of manufacture is also provided. The assembly of this invention represents an improvement over prior art squib assemblies, such as the BBU48. In preferred embodiments, the assembly comprises a brass base plate, a pair of squibs, a center contact connected to the squibs, and a zener diode connected between one of the squibs and the baseplate. All of those components are retained within a molded rubber or plastic body, which is shaped to hold the components in the desired relative position and to form sealing elements around each of the squibs. A reliable, integral assembly is thus provided using a minimal number of parts and electrical connections. In alternative embodiments, a larger number of squibs may be incorporated into the assembly, and alternative discrimination elements may be employed.
