Abstract: Electrical joint apparatus includes an array of stab connectors each having a pair of spaced contact fingers and an array of receiver connectors each also having a pair of spaced contact fingers arranged in individual lapped relation with respective contact fingers of an associated stab connector. Heat sinks are mounted with suitable insulators between the contact fingers of adjacent stab connectors and also between the contact fingers of each receiver connector. A clamping rod extends freely through aligned apertures in the stab fingers, heat sinks and insulators and through notches in the receiver fingers and the heat sinks mounted therebetween. The compression springs are carried by the rod at each end of the stab connector array.
