A post-insulated wire splice includes a conductive connector and an insulating member surrounding the connector. The connector includes a ferrule crimped around at least two wires, the ferrule having a generally smoothly curved exterior surface and having outer and inner ends defined with respect to the wires; the wires extend externally beyond the ferrule inner end and are terminated adjacent the ferrule outer end. The connector has a separation portion extending beyond the ferrule outer end, including an exterior surface continuous with the ferrule exterior surface and a sheared edge remote from the ferrule. The separation portion is deformed from a shape coincident with a portion of the projection of the ferrule exterior surface to displace the sheared edge inwardly of the projection toward the wires. The insulating member comprises a generally tubular sleeve of insulating plastic material, and in preferred embodiments is crimped and closed around the extending wires beyond the ferrule inner end. The insulating member fits closely around the connector and the connector sheared edge is spaced inwardly from the insulating member.

Insulated wire splice

Apparatus for assembling post insulated wire splices, each assembled splice having first a connector crimped around the wires and next insulation therearound, comprises wire gripper means to retain wires to be spliced in a fixed splice working position, connector forming means for crimping a connector around the wires, and connector feed means to supply a connector to the connector forming means. The connector forming means is movable between a position remote from the splice working position and a crimping position in which the forming means crimps a connector around the wires retained by the wire gripper means in the splice working position. The apparatus further comprises insulation assembly means for assembling insulation around the connector, and insulation feed means to provide insulation to the insulation assembly means. The insulation assembly means is movable between a position remote from the splice working position and an operating position in the splice working position.
