ABSTRACT:
An electrical jack of the composite prong type having a leading end portion comprising a tapered tip component of an axially extending tip contact member. The tapered tip component has a proximal end portion terminating in a circular flange which has first diameter and is integrally joined to a rod component of much smaller diameter through a reinforced length component of intermediate diameter. The reinforced length component has a cross sectional size designed for uniformly distributing impact stresses transmitted from the tapered tip component, and has a length greater than its intermediate diameter for minimizing impact stresses transmitted to the rod component. The reinforced length component is slidably installed in a cup-shaped dielectric bushing having a flanged open end portion abutting the circular flange of the tapered tip component. The cup-shaped bushing has an opposing closed end provided with a central aperture through which extends the rod component and an encircling dielectric sheath. An outer sleeve contact member has an end portion provided with an enlarged diameter cavity wherein the dielectric bushing is slidably inserted until the adjacent end of the sleeve contact butts against the flanged open end portion of the bushing. The cavity in the sleeve contact member communicates with a smaller diameter bore through the dielectric sheath and the encircled rod component extend.
