An electrical connector assembly is described. The electrical connector assembly includes a first connector body, a second connector body, a first removable cap, and a second removable cap. The first connector body has a first connector end, a first cap end, and first and second electrodes that protrude from the first cap end. The second connector body has a second connector end, a second cap end, and third and fourth electrodes that protrude from the second cap end. The first and second removable caps each have a cavity, formed by an outer wall portion that shields the corresponding electrodes, and an interior wall portion that shields at least a portion of the corresponding electrodes. Upon an engagement of the first and second connector bodies, the first connector end abuts the second connector end, the first and third electrodes are electrically connected, and the second and fourth electrodes are electrically connected.
