Safety stab technology

Abstract

A stab (pin and sleeve) electrical connector with improved safety is described. The female (sleeve) connector exterior surface is coated or made from with a nonconductive insulating material. A pressure loaded insulator plug is disposed inside the female sleeve. An electrical connection is made when the male (pin) connector is inserted into the female sleeve. The male pin contacts the insulator plug inside the female sleeve, causing compression, and makes electrical contact with the uninsulated inside of the sleeve. As the male pin is removed, the pressure mechanism of the insulator plug pushes the plug out flush with the external insulated surface making the female sleeve touch safe. Therefore, embodiments provide a high level of safety for the pin and sleeve electrical connection method without adding large or troublesome moving parts.
