Abstract: A connector box for coaxial cable includes a metal shell made from a stamping and folded into a box shape, a spacer structure of non-conductor, an inner connector and a cover. Insulation displacement slots in the shell wall with sharpened vee-shaped entries and in-turned edges engage a cable outer conductor. A stepped passage in the spacer structure positions the cable during insertion. Insulation displacement slots with vee-entries in the inner connector are aligned with those of the shell and engage the inner conductor of the cable.

Abstract: A piston-cylinder seal uses gas for a lubricant and has a runner supported on a gapless structure and placed in the space between the piston and the cylinder wall. The runner is deformed elastically under the influence of the operating pressures to follow and compensate for variations in the piston-cylinder fit and maintain a seal.

Abstract: A device for connecting shielded pair has a base holding a shield bus and two conductor buses. Each bus is formed from sheet metal stock and positioned to provide a wall at right angle to the floor of the base. The buses have insulation displacement slots situated away from the floor of the base. The base and a cover cooperatively form line entrance structures which are aligned with the slots in the shield bus and resist rotating of the lines. The cover has structures which retain the conductors in place. The base has structures supporting the shield bus in proximity to the displacement slots.
