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: An electrical connector system has a contact member with a tunnel portion and spaced, vertical contact pillars secured within the tunnel portion. Extensions of the contact pillars bind the contact member to a metal plate in staple-like fashion. The metal plate is preferably useful as an electrode for medical electronic equipment. A cable connector which snap-latches directly to the contact pillars has an encasement formed of semi-flexible arm members joined at a base portion. A wedge-shaped frontal portion is positioned at the end of each arm member such that points of the adjacent frontal portions are spaced less than the spacing between the contact member contact pillars. A notch is provided rearward of the frontal portions on each of the arms for latching to each of the contact pillars when the cable connector is pushed into the tunnel portion of the contact member.

Abstract: A soldering iron for soldering a plurality of wires to metal liners in respective channels of a connector. The soldering iron can be used with a known wire positioning device. The iron is made from a plate of heat conducting material. A plurality of projections extend fron an end face of the plate. The projections are spaced to correspond to the spacing of the metal liners in the channels of the connector which is being joined to the plurality of conductors. The sides of the projections converge toward the extremities of the projections. These converging sides are plated with a material to prevent oxidation and to cause the solder to wet the sides. The projections are dimensioned so that their extremities can be positioned within the channels while the converging sides contact respective edges of the metal liners in the channels. In such position, heat is conducted by the iron in order to solder the wires placed within the channels to the metal liners.
