In the prior art, the boundaries have been preset subjectively. By utilizing learned samples, the present invention is able to insure that the particular boundaries are proper given the particular size of wire, the particular type of connector, and particular arrangement of machinery that is being monitored.

Abstract: A method of controlling a crimp press for crimping an assembly includes the steps of placing an assembly in an open crimp die of a crimp press, advancing a ram of the crimp press to a predetermined position to close the crimp die, determining whether a pressure in the ram is within a predetermined range, and alerting an operator if the pressure in the ram is not within the predetermined range.

Abstract: The present invention is directed to an apparatus and method for a unique crimping applicator which significantly advances a carrier strip (1.3 inches) to allow for the crimping of widely spaced terminals and a large variety of terminal sizes and configurations.

Abstract: A device for crimping a plastically deforming metal pole shoe (1) around the end (2) of a cable that has been inserted into it. The device comprises an anvil (3), a die (4), a sensor (5), and a comparator (6). The shoe is placed on the anvil and the die is advanced toward it, deforming the shoe. The sensor emits a signal once the shoe has been deformed to the maximum, and the comparator compares the signal with a reference and emits either an "accept" signal or a "reject" signal. The "reject" signal emitted by the comparator actuates a cable-end trimmer that cuts part-way or all the way through the cable. Consequently, the device will always either acceptably crimp pole shoes to the ends of cables or reliably indicate defective connections.

The end (156) of the anvil terminates at each side wall (158, 160) in somewhat sharp edges (168, 170), respectively, that curve outwardly to help prevent the formation of a burr on the crimped connection.

Abstract: An applicator for installing pre-insulated crimp connectors on the bare ends of electrical wires has a body with a straight-through passageway which permits loading a single connector in the applicator with a pulse of pressurized air. The connector is propelled by the air pulse from a supply station through a flexible hose into and almost all the way through the applicator. A flexible retainer prevents the connector from exiting the applicator under the influence of the air pulse. After the connector is stopped by the retainer a pair of indentors close on the connector and hold it in a ready position, waiting for a user to insert the wires to be connected and issue a command to crimp the connector. Upon receipt of such command the indentors apply a crimping force to the connector and advance it past the retainer.

Accordingly, it is possible to prevent crimping defects caused by exclusion from the terminal of one or more wire ends.

A second crimping die is mounted on the applicator ram for cooperation with the anvil to crimp a second portion of the terminal onto the insulation of the electrical wire during each working stroke of the applicator ram. A first adjusting plate is mounted for rotation about an axis on and extending in the direction of movement of the applicator ram to selectively interpose projections between the press ram and the applicator ram to adjust the shut height of the first and second crimping dies.

Abstract: A system for attaching electrical contacts to the conductive ends of wires preferably provides simultaneous sorting operations, wherein different contacts from separate batches are simultaneously sorted in consecutive order; preselection operations, wherein contacts stuck together are removed; simultaneous holding operations, wherein presorted contacts from each batch are accumulated in separate, automatically resupplied queues, for rapid subsequent retrieval by the operator; pneumatic transporting operations, wherein contacts are rapidly retrieved from any queue selected and prealigned opposite the crimping jaws of a crimping unit; and two-step crimping operations, wherein prealigned contacts are quickly gripped by partially closed crimping jaws, in the first step, in preparation for the second step of wire end insertion and full crimping.
