Abstract: A method for applying a shield tape to conductors that comprises folding a first edge of the shield tape in a first direction from a central portion while folding a second edge in a second direction opposite the first direction; applying a fold to the first edge by folding the first edge back over onto the central portion forming a receiving area while wrapping the shield tape around the conductors; tightening the shield tape around the conductors such that the conductive layer of the shield tape is on the outside of insulating layer and facing away from the conductors while positioning the receiving area to receive a drain wire; installing a drain wire in the receiving area; and closing the shield tape around the conductors and the drain wire to form an enclosure around the conductors with the second edge overlapping the fold at an outside surface of the enclosure.

Abstract: A communication cable that comprises a jacket, a twisted wire group, and a single separator received in a core of the jacket. The separator includes a body that has first and second segments adapted to define quadrants in the communication cable. The first and second segments are substantially perpendicular to each other and define a junction point of the first and second segments. Each segment includes a main portion and a terminal end remote from the junction point of the segments. Each of the terminal ends has a shape such that each of the terminal ends is wider than the main portions of the segments. An air pocket is defined between the terminal ends of the first and second segments. The air pocket includes a gap sized such that the air pocket is substantially enclosed, wherein the twisted wire group is prevented from entering the air pocket.

Abstract: In an electrical connector for an electric vehicle, the spring latch is not sealed; instead, the connector body has holes allowing water entering the spring latch mechanism to drain harmlessly out of the connector. A forward-facing LED or other light source acts as a flashlight. Once the connector is connected, the forward-facing LED is switched off, and a rear-facing LED or other light source is switched on to confirm that the connector is connected and capable of charging the vehicle. The connector is produced by overmolding in a three-layer configuration, where each layer is formed of a material having advantageous materials for that layer's position in the connector.
