Abstract: To increase the rigidity of the cutter plate portions formed with two open slots for cutting a wire insulator pressure-fitted thereinto, the wire insulator pressure-cut connector terminal comprises a base plate portion, a brimmed channel-shaped frame formed with two opposing cutter plate portions and two brim portions, and a reinforcement portion formed with two brim holder portions. Further, since the brimmed channel-shaped frame can be formed by bending a blank plate material with two mated dies having no hollow cavity between the two dies, the pressure-cut terminal can be bent into an accurate shape and in precise dimensions for providing a higher reliability of the connector terminal.

Abstract: An insulation displacement connector (IDC) having internal sealing material which is packed around the wires as the connection is made. The IDC has a plurality of channels for receiving the wires, and at least one metallic element providing electrical contact between the wires. A plurality of voids are in fluid communication with the channels, and the voids are filled with the sealing material, such as a mastic or silicone grease. When the IDC is moved from an open to a closed position, the metallic element makes contact between the wires, and a piston or post subsequently enters the voids, causing the sealant to flow into the channels about the wires and the contact interface.

Abstract: An insulation displacement terminal having a pair of slotted plates retained in a nest formed by embossments on sidewalls extending past the edges of slotted plates. The sidewalls and the slotted plates are formed orthogonally upward from a common base. Outer ellipsoidal embossments are formed on opposite sides of a cylindrical embossment. The embossments are formed by a shallow drawing process without removal of material from the planar sidewalls. Adjacent edges of the embossments are sheared to form a nest receiving the side edges of the slotted plates.

Abstract: The contact member defines a channel having a base from which project side walls bowed in portions of which define wire slots. Inwardly convergent wings surmounting each wire slot have insulation severing edges. When a lead is forced into the channel the edges sever the insulation of the lead so that the crests of the bowed portions engage the core of the lead. The wings are then bent across the channel to hold the lead down therein. The portions merge with dimples in the base so that the side walls and the base are continuous as seen in cross section through the wire slots, so that the rigidity of the contact member and the contact force exerted against the core, are improved.
