Abstract: A rugged and durable, detachable electrical connector assembly is disclosed comprising removable engaging and stationary receiving complementary connector parts. Each connector part includes a housing, a terminal block, and a respective plurality of either electrical pin or socket contact members. The respective pin and socket contact members are electrically interconnectable in a mating relationship with one another by inserting the engaging connector part within the housing of the receiving connector part. The housing of the receiving connector part is provided with a unique configuration to enable the engaging connector part to be accurately aligned in each of three orthogonal directions therewith, so that the engaging connector part can be guided into a detachable connection with the receiving connector part.

Abstract: An electrical penetrator assembly for conveying electrical wires through a wall which separates a hostile environment from an adjacent environment suitable for access by human operators. The assembly comprises a unique modular construction formed by a plurality of lead disks each having at least one aperture of axial direction and location appropriate to form a continuous spiraling passageway that is skewed with respect to the axis of the penetrator along at least portions thereof to substantially reduce or eliminate inadvertent escape of the hostile environment through the assembly. The assembly also comprises a positionable connector platform on which connector assemblies provide suitable interconnecting pin structure to mate wires contained within the penetrator to interconnecting cables within the hostile environment.
