The latest series of 3M™ Scotchlok™ Insulation Displacement Connectors (IDCs) has kept all that was good about the original connector - the design, the shape, the element technology and the color-coding. Our unique "U" contact provides a dependable electrical connection. A "live-spring" joint is made by driving the "U" contact down into the connector. As the "U" contact is pressed into the connector, it grasps the conductors as it displaces the insulation. Contact grips the conductor and holds with a firm, resilient pressure.
