Miller, J S

Tests were conducted to measure the shielding effectiveness (SE) of the shell-to-shell interface of sample bayonet connector shells with fingers. A quadraxial test fixture consisting of a triaxial input circutt and a 50 ohm coaxial.output circuit was used. Samples of MIL-C-38999B cormectors from Bendix, Cannon, and Hughes were tested. Test procedures included reflection and resistance measurements, and consideration of variables such as finger slot width, millivolt drop, finish, finger attachment method, insert removal, coupling ring lubricant, and current amplitudes over frequencies from 200 KHz to 50 MHz. Detailed test results and diagrams of test apparatus are included. Connectors having narrow gaps (slot width) between fingers and low finger contact resistance had the best attenuation. (auth)
