Abstract: A conjugate electrical connector with improved contact conductivity having slots or grooves in one terminal and rounded protrusions on the opposite terminal. This contact feature provides for two lines of contact points per protrusion/slot pair where the protrusion touches the two edges of the slot whereas the closest prior art only provides one line of contact where a protrusion contacts a terminal without a slot. The amount of energy lost in heat dissipation due to contact resistance is reduced. Additional advantages include: the terminals will lock together with a mechanical confirmation, the terminal will seat in the same place each time it is connected, and movement between the terminals is less likely.
