Abstract: An electrical connector crimping die comprises a first section for removably connecting the die to an electrical connector compression tool. A second section of the die, which is connected to the first section, is provided for crimping a connector. The second section comprises a generally concave crimp projection of a given height which defines a primary crimp surface and at least one concave shaped secondary pre-crimp surface. The secondary pre-crimp surface is recessed relative to the primary crimp surface by the given height. The primary crimp surface and the secondary pre-crimp surface are arranged relative to the first section so that a major portion of a crimping force applied by the compression tool to the crimping die is applied to the primary crimp surface to crimp a first portion of the connector and so that a minor portion of the crimping force is applied to the secondary pre-crimp surface to pre-crimp a second portion of the connector. A hydraulic crimping tool employs such a crimping die.

Abstract: A pair of pin press-connecting pliers. The pliers include a first handle and a second handle pivot connected via a connecting seat. The first handle is provided on the inner side thereof with a guiding portion. A first press-connecting portion is provided in the guiding portion, and a linking member connects the first press-connecting portion with the second press-connecting portion. A second press-connecting portion is fixedly provided on the tailing end of the guiding portion via a die block. The connecting seat has at least a concave portion at the press connecting area of the first and the second handles for resting a wire thereon, and has a knife provided on a corresponding handle for peeling or cutting wire in cooperation with the concave portion.

Abstract: A hand-held tool for terminating connectors onto a coaxial cable has an elongated body and an end stop and plunger on the body, the plunger being controlled by a lever arm which will axially advance the plunger toward and away from the end stop to radially compress a portion of the connector into firm crimping engagement with the end of the coaxial cable. To accommodate different lengths of connectors, a receiver is resiliently mounted on the plunger for insertion of different length adapter tips to vary the axial spacing between the receiver and the end stop according to the length of connector being terminated; and in still another form the body may include a hinged adapter adjacent to the end stop to vary the effective distance between the end stop and plunger according to the length of fitting being terminated.

Abstract: Hand held tools have been devised for preparing and crimping cables and specifically coaxial cables for television, a first form of tool made up of a low profile body having a main channel with a threaded crimping bolt for crimping circular fittings by axial compression onto the end of the cable, and a second form has a main channel which utilizes the same crimping bolt to carry out hexagonal crimping operations; and both forms have a channel for preparing each cable end for the crimping operation in which stripper blades are pivotally mounted for movement into engagement with the cable end to strip away one or more layers of the cable under the control of an adjustable limit stop which regulates the depth of penetration of each blade.

Abstract: Electrical terminal fastening dies are provided, which includes: an electric wire; an electrical terminal having the electric wire; a couple of dies to press the electrical terminal a substantially hexagon in cross section; an abutting plane provided on each of the couple of dies; a pressing groove provided on the abutting plane and having a section to be formed by dividing a hexagon symmetrically with a diagonal; a pair of terminal pressing planes formed on a surface of the pressing groove of at least either one of the couple of dies for pressing the electrical terminal; and a pair of flash preventing planes formed on the surface of the pressing groove having the pair of terminal pressing planes, and each connected to the abutting plane, for pressing the electrical terminal to form thin portions thereon so as to prevent a flash from arising on the electrical terminal.

Abstract: A tool for stripping the jacket, conductive braid and dielectric layer of a coaxial cable to the correct length required for attachment to a coaxial cable connector, and for attaching the stripped end of the coaxial cable to a coaxial cable connector by means of crimping. The stripping portion of the tool has a dual blade cutter that has preset blade separation, fixed cutting depths, and includes preset spring pressure to insure a complete cut. The tool further includes means for applying the force needed to hexagonally crimp a compression crimp ring having a length of up to ½ inch on a standard coaxial cable connector in order to attach the connector to the stripped cable. The invention provides an economical tool, and method for using the tool, for hex crimping a compression crimp ring of up to ½ inch in length on standard coaxial cable connectors.

Abstract: A terminal applicator comprising a terminal advancing mechanism which includes a mechanism for reciprocally advancing and retracting a feed finger which resiliently biases a terminal strip from a first position to a second advanced position in alignment with a crimp die, and a device for controlling reciprocal movement of the advancing mechanism by interacting with the feed finger, whereby feed and retract limits are defined.

Abstract: Hand operated press for installing cable connectors basically includes two handle bars; a receptacle; and a nose, wherein each handle bar has a grip at its lower end and compression part at its upper end. The receptacle and the base are fixed to receptacle compression parts, and a terminator and an adapter are set on the receptacle and the base. When a compressive force is applied between two grips, both receptacle and base move inward simultaneously so as to engage the adapter and the terminator in one piece. Moreover, the receptacle and the base are replaceable with various sized ones to meet the requirement of compressing terminators of different sizes.

Abstract: Electrical terminal fastening dies are provided, which includes: an electric wire; an electrical terminal having the electric wire; a couple of dies to press the electrical terminal a substantially hexagon in cross section; an abutting plane provided on each of the couple of dies; a pressing groove provided on the abutting plane and having a section to be formed by dividing a hexagon symmetrically with a diagonal; a pair of terminal pressing planes formed on a surface of the pressing groove of at least either one of the couple of dies for pressing the electrical terminal; and a pair of flash preventing planes formed on the surface of the pressing groove having the pair of terminal pressing planes, and each connected to the abutting plane, for pressing the electrical terminal to form thin portions thereon so as to prevent a flash from arising on the electrical terminal.

Abstract: An electrical connector crimping die comprising a first section for removably connecting the die to an electrical connector compression tool; and a second section connected to the first section for contacting an electrical connector. The second section comprises a generally crescent shaped crimp projection forming a crimp surface and at least one secondary over-crimp prevention surface. The secondary surface is recessed relative to the crimp surface and has a general radius of curvature larger than a general radius of curvature of the crimp surface.

Abstract: An electrical connector crimping tool head comprising a frame; and a ram movably connected to the frame. The ram comprises a first member and a second member longitudinally movable along the first member. The first member comprises a shaft section removably insertable into a rotatable drive for a fixed connection to the rotatable drive.
