Abstract : This final report covers an investigation into the design and evaluation of a single wire termination system capable of interconnection to various existing designs of multicontact connectors. The devices utilizing this termination system were to be capable of assembly and maintenance with a common tool. In addition, the devices were to reliably withstand the environmental conditions encountered by ground and airborne Army equipment with emphasis on improvement for Army aircraft. The concept designed and evaluated makes waterproof connectors having crimp removable MS27491 series contacts practical to produce. However, to obtain sound insert moldings, minimum spacing between contact centerlines had to be established as follows: Terminal Size 22D, 20, 16, 12, in the Minimum Space of .090 in. (tentative), .130 in., .190 in., and .238 in. respectively. It was found that the contact spacing of MIL-C-81511 connectors is inadequate for use with M527491-22D contacts. Terminal insertion and removal tools were obtained, evaluated, and found useful. Terminal insertion and removal tips used for 22D contacts were mechanically weak. If the tip wall section must be increased, which is still to be determined, or if the dielectric wall thickness between contact cavities is inadequate for a reliable design, then the .090 in. spacing for this contact size may have to be increased.
