Abstract: A connector block including wire-formed multiple solderless connectors. The block has retainer and body sections with slots and bridge elements to house and define rows and columns of the connectors. The block is further provided with wire wrap pins which project from one side of the block and which are in mechanical and electrical contact with the wire formed solderless connectors.

Abstract: A tool for inserting a wire between resilient contact portions of a connector. The tool has a handle portion and a reversible stem portion and the stem portion includes a blade extending from opposite sides thereof. The blades are generally in the form of I-beams and, in use, the channels at either side of the beam engage the connector contact portions while the web portion of the beam serves as anvil which supports the wire in the region between the contact during insertion.

Abstract: A telephonic distribution panel assembly is comprised of three identical panels which are removably attached to one another. These three identical panels are arranged to form a three sided frame. The assembly provides easy access to various types of telephonic equipment which may be mounted to the frame.

Abstract: A mounting block for solderless connectors has a retainer and a body section which defines slots for housing terminal defining conductive elements to thereby define rows and columns of terminals. The conductive elements are formed from wire to define linearly aligned plural loops between which wires may be inserted. The block supports the conductive elements so that relative lateral movement between the loops is precluded.

Abstract: An electrical panel connector hold-down adapter which permits electrical cable connectors of various size and shape to be easily and reliably secured to mating electrical panel connectors.

Abstract: A wire installing tool for inserting wire into a multifingered electrical connector comprising a handle containing a reversible elongated stem having recesses on both ends; the recesses being sized differently in depth to adapt to electrical connectors having various thicknesses, and a disposable blade releasably mounted on the stem and aligned with the recess to form a cavity which is bounded on three sides by the stem and on the fourth side by the blade, the depth of the cavity dependent upon which end of the stem is aligned with the blade. At least one end of the blade has a two-sided edge, the outer side shaped at an optimum shear angle for shearing wire to be inserted in the electrical connector, and the inner side of the edge being shaped to allow for a wire tail to protrude a predetermined distance from the electrical connector.

Abstract: An electrical circuit tester for use in testing terminal blocks having protruding electrical connectors, the tester comprising a body made from an insulating material, the body having a plurality of circuit testing assemblies, each assembly including a chamber, each chamber including a chamber extension extending to the exterior of the body and capable of receiving the electrical connectors. Positioned within each chamber is a piston having a piston rod extending therefrom, the piston rod extending into the chamber extension. The chamber includes a piston retaining wall having an aperture through which the piston rod moves. When the piston rod is in its fully extended state, there is room in the chamber extension to receive the electrical connector. Positioned within the chamber is a conductive grommet and a resilient conductive spring which contacts the grommet and functions to urge the piston and piston rod to the fully extended position.

Abstract: A mounting bracket for use in mounting quick connect circuit blocks to a wall or pipe comprising a pair of flanges for attachment of the bracket to the wall, a block supporting beam for supporting the circuit block, the block supporting beam being parallel to and spaced from the flanges by connecting webs. A pair of dowel-like protrusions project from the center of the beam and provide a fixed point about which the terminal block can be suspended and allowed to pendulate and come to rest in a vertical position. A method of mounting the bracket is disclosed wherein a first bracket is leveled and mounted on a wall, a second bracket is affixed to a first circuit block, and the first circuit block is suspended from one of the dowel-like protrusions and allowed to pendulate and to come to rest in a vertical position. The circuit block is then affixed to the first bracket and the second bracket is affixed to the wall.

Abstract: A wire installing tool for inserting wire into a multifingered electrical connector comprising a handle containing a reversible elongated stem having recesses on both ends; the recesses being sized differently in depth to adapt to electrical connectors having various thicknesses, and a disposable blade releasably mounted on the stem and aligned with the recess to form a cavity which is bounded on three sides by the stem and on the fourth side by the blade, the depth of the cavity dependent upon which end of the stem is aligned with the blade. One end of the blade has a two-sided edge, the outer side shaped at an optimum shear angle for shearing wire to be inserted in the electrical connector, and the inner side of the edge being shaped to allow for a wire tail to protrude a predetermined distance from the electrical connector. The other end of the blade has a blunt end rather than a cutting edge, the blunt end being used to install wire on an electrical connector without cutting the wire.

Abstract: An electrical circuit element which defines a conductor matrix having column and row conductors is characterized by field repairability and ease of programming and reprogramming. The circuit element comprises a matrix terminal block which serves as a housing for commonly bussed individual terminal elements and plural integral multiple terminal elements.

Abstract: There is disclosed a terminal connecting block and bracket assembly. The terminal connecting block contains a plurality of flat elongate electrically conductive elements. Each element in the block comprises a flat base portion and at least one pair of opposing insulating shearing contact fingers projecting from the base portion and integral therewith. The opposing contact fingers project upwardly from the terminal block. Each electrically conductive element also contains a tang projecting from the opposite end of the base portion. A plurality of the electrically conductive elements are in electrical contact with a unitary electrical connector, e.g., a male or female connector, by means of electrically conductive wires. One end of each wire is attached to one of said tangs and the other end of each wire is attached to the unitary electrical connector. The terminal connecting block is used in combination with a bracket for mounting the block on a surface.
