Abstract
A Kelvin clamp for coupling a first electrical conductor and a second electrical conductor to a battery contact to provide a Kelvin connection to the battery contact. The Kelvin clamp includes a first electrically conductive arm having a first grasping portion that can couple to the battery contact and to the first electrical conductor. Also included is a second arm that has a first electrically conductive piece and a second electrically conductive piece, which are mechanically coupled together and electrically isolated from each other. The first electrically conductive piece has a second grasping portion that can couple to the battery contact. The first electrically conductive piece can also couple to the second electrical conductor. The first electrically conductive arm and the second electrically conductive piece are electrically and mechanically coupled together by a spring mechanism.
