Abstract
Abstract An electrical connector is disclosed which makes connection to one or more unstripped insulated conductors. The connector includes a movable contact assembly disposed in a cavity for movement between open and closed positions. The connector includes a fixed contact electrically coupled to a contact of the movable contact assembly at least in the closed position of the movable contact assembly. The cavity is sealed except for one or more inlets through which one or more conductors are inserted into the cavity for connection. The cavity receives a water-proofing or sealing compound. The connector is constructed so that the cavity volume is constant in both the open and closed positions and during travel of the movable contact assembly. Thereby, compound is not forced out of the cavity when a conductor is connected or disconnected, i.e., when the movable contact assembly is moved. An activator for moving the movable contact assembly is insulated from the contacts of the connector at all times. The connector may connect each conductor of a communication pair of either a two-conductor drop line or two single conductor lines to a different fixed contact of the connector. Connection of the two conductors of the pair to the connector is made at the same time. The connector is constructed to accommodate a range of insulated conductor sizes. A connector assembly may comprise a plurality of connectors in a common housing.
