This report covers results of a study to design and develop an alternate configuration for the enclosure seal of the M1139 fuze. The objective of the study was to improve the method of sealing the fuze by preventing possible deterioration of wire termination andor possible degradation of the operational characteristics of the fuze which might result from the present method of sealing, e.g. induction soldering. Prime consideration was given to maintaining the exact mechanical and electrical operating element configuration of the existing fuze. Thus, proven performance characteristics, supported by test data accumulated over several years production, will not be changed by the cover and seal modification. The design described in this report eliminates the application of heat sealing the receptacle and receptacle and plate assembly to the fuze body. The design makes provision for mechanical fastening of the receptacle and plate assembly in conjunction with a silicone rubber O-ring seal.
