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.
Claims9
A crimp connector applicator, comprising:
- a handgun having a body with a passageway through it, the passageway defining an axis and having an inlet at one end and an outlet at the other end, the cross-section and configuration of the passageway being such that a crimp connector can be propelled by a single pulse of air pressure into the inlet and through the passageway to the outlet;
- a retainer pivotally attached to the handgun near the outlet and biased into the outlet such that the retainer will prevent a crimp connector propelled by air pressure from exiting the passageway, the retainer thereby defining a crimp station near said other end of the passageway;
- at least two indentors mounted in the handgun and movable toward and away from said axis;
- and
- actuator means mounted in the handgun for moving the indentors between a load position, wherein the indentors are outside of the passageway such that the passageway is unobstructed from the inlet to the retainer, a ready position, wherein the indentors move into the passageway and engage a connector located at the crimp station with a non-crimping force, and a crimp position, wherein the indentors engage a connector located at the crimp station, crimp said connector and advance it at least partially past the retainer.
In a machine for installing crimp connectors of the type having a connector supply for feeding individual crimp connectors one at a time through a flexible hose to an applicator, the hose being connected to an inlet of the applicator, the applicator having a crimp station near an outlet for discharging the connectors and a passageway connecting the inlet and outlet, and crimping means in the applicator for crimping connectors at said crimp station onto wires, an improved method of installing the connectors comprising the steps of:
- propelling a single connector by means of a single pulse of air pressure from the supply, through the hose, into the inlet and through the passageway;
- arresting movement of the propelled connector at the crimp station;
- engaging a connector at the crimp station with a crimping tool to hold the connector at the crimp station until a user activates the applicator;
- and
- upon activation of the applicator by a user, crimping the connector onto wires while advancing the connector from the crimp station to the outlet.
