Abstract: A field termination tool for electrical connectors includes laterally floating combs having edges which engage respective longitudinal slots on each side of an electrical connector to define a reference plane, the connector being urged toward the reference plane by a wave or blade spring carried on the connector support. The insertion tool is constructed to force insulated conductors into respective insulation piercing portions of connector contacts equally well for different connector widths by apparatus for positioning one of a pair of oppositely directed rotatable insertion arms with respect to the other and to the connector support and by providing a floating support structure to equalize forces across a connector. The comb slots each have a cutting edge which is cooperable in a scissor action with the cutting edges of the insertion blades carried on the insertion arms to cut the conductors immediately prior to insertion.

Abstract: A termination apparatus for electrical connectors, which includes an improved apparatus for applying operating forces from an apparatus operator to rotatable insertion arms, is provided for use in inserting a plurality of insulated conductors into respective insulation piercing contact portions of an electrical connector. The disclosed apparatus includes a frame, a removable support structure for a connector, which aligns the insulated conductors adjacent respective insulation-piercing contact portions of the connector, a pair of oppositely disposed insertion tools that are rotatably mounted on the frame for movement toward and away from each other and that carry insertion tools for inserting the insulated conductors into the connector, and an assembly that more effectively applies and distributes operating forces to the insertion arms during a termination cycle.

Abstract: A pi pin filter employs a tubular ferrite which receives a pin contact therein. The ferrite tube is metalized over at least a portion of its inner surface, at least two portions of its outer surface, and about its ends and receives the pin contact therein for electrical connection to the metalization by means of a spring contact, solder bonding or fusing. A plurality of dielectric layers extend radially of the ferrite tube and are bonded together to form an integral structure having metal capacitor plates between the layers. Some of the capacitor plates are interconnected, by a metalization to form the ground plates for connection to the metal shell of an electrical connector, while others of the metal plates located intermediate the first-mentioned metal plates are interconnected in two separate groups by a separate metalizations which, upon assembly, are fused to the respective metalized areas on the outer surface of the ferrite tube.

Abstract: Apparatus is disclosed for terminating insulation covered conductors in the individual contacts of a multiple contact connector. The apparatus includes a base or connector-holding jig and an insertion tool. The base includes means for holding the connector in conductor mounting position; stationary and retractable comb elements for aligning the individual conductors with the proper contacts of the connector; and shear means. The tool includes a transverse guide portion and a longitudinal blade which form a generally T-shaped tool head. The tool head is configured to cooperate with slots formed in and by the comb elements to position the tool in proper alignment for the trimming and mounting operations.

Abstract: Techniques for terminating a plurality of free-ended insulated electrical conductors in respective insulation-piercing contacts carried in respective parallel channels of an electrical connector include supporting the connector on a base with the channels exposed to receive the respective conductors, and moving an insertion tool generally parallel to the connector to sequentially insert the conductors within the respective channels and insulation-piercing contacts. The connector may advantageously comprise a notched ridge, with each notch in communication with a respective channel for preparatory alignment before insertion. The entire terminating apparatus resembles a credit card impression mechanism with a wheeled carriage supported to traverse a base in opposite directions. In one embodiment, a wire cutter, supported by the carriage, advances in front of the insertion tool to cut the ends of the wires before insertion.

Abstract: An interconnection module for a termination system, in particular for key telephone termination systems, includes a front panel, a back panel spaced from and secured to the front panel, an array of patch-cord type connector contacts supported in vertical and horizontal rows by and extending through the front panel, and a plurality of separable electrical connectors having one mating part thereof mounted on and extending through the back panel. A vertical row of contacts on the front panel is associated with an electrical connector mounted on the back panel and the individual contacts of such an association are interconnected in the space between the front and back panels by a flexible printed circuit arrangement which is constituted by one or more multi-layer printed circuits.
