A multipoint contact compression connector provided with a plurality of recesses to include a like number of electrical conductors or cables therein. When placed in an appropriate crimping device, the connector would contact the interior die surfaces in at least four points, in such a manner, so as to secure at least three conductors or cables in place.

Multi-point contact compression connector

A power booster bushing for obturating powder gases in a cartridge case employed by power actuated tools used for connecting power cables. The power booster bushing supports an explosive power cell and is slidably positioned in the cartridge case bore and has a series of ribs defined by grooves engaging the cartridge case bore. The interface between the cartridge case bore and the bushing is sealed during detonation of the power cell by means of the circumferential ribs. The bushing undergoes an 'accordion effect' during detonation characterized by axial compression of the bushing and resulting in the prevention of powder gas escape through the open breech end of the cartridge case.
