  • Publication number: 20150372437
    Abstract: A terminal crimping machine includes a termination tool having crimp tooling defining a crimping zone that receives the terminal and the wire. The crimp tooling is actuated during a crimp stroke to crimp the terminal to the wire. The terminal crimping machine includes a wire clamp holding the wire near the crimping zone. The wire clamp releases the wire prior to completion of the crimp to allow extrusion of the wire during the crimping process. Optionally, the wire clamp may release the wire prior to bottom dead center of the crimp stroke. The wire clamp may release the wire after the terminal partially retains the wire.

  • Publication number: 20150052740
    Abstract: A terminal crimping device includes crimp tooling comprising an anvil and a ram movable toward the anvil with a crimp zone being defined between the anvil and the ram configured to receive a wire and a terminal configured to be crimped to the wire by the crimp tooling. An ultrasonic transmitting transducer is coupled to at least one of the anvil and the ram that transmits acoustic signals through the wire and terminal.

  • Patent number: 7774927
    Abstract: A wire positioning device for a termination machine includes a support housing configured to be located proximate to a termination zone of the termination machine. A wire gripping mechanism is coupled to the support housing and defines a wire alignment axis. The wire gripping mechanism is configured to hold a wire along the wire alignment axis. The wire gripping mechanism and wire are movable with respect to the support housing along a linear transfer path that is oriented transverse to the wire alignment axis. An electric actuator is mounted to the support housing and is joined to the wire gripping mechanism. The actuator drives the wire gripping mechanism along the transfer path.

  • Patent number: 6807719
    Abstract: An apparatus for inserting terminals carried on a carrier strip into cavities in a housing having a slide assembly with a cam track movable between a first and a second position, and a pivoting lever with a cam follower. The cam follower is positioned in and cooperates with the cam track. The lever is movable between an open and closed position and has first and second shearing blades. An eccentric pin extends through the lever and is attached to a rotary actuator. The eccentric pin is positioned to act as the pivot point for the lever. The rotary actuator is movable between an engaged and disengaged position. As the lever is moved to the closed position, the first shearing blades engage and shear a first portion of the carrier strip. As the rotary actuator moves to an engaged position, the second shearing blade engages and shears a second portion of the carrier strip.

  • Patent number: 5855294
    Abstract: A terminal insertion machine (10) includes a feed unit (14) for feeding a strip (16) of terminals into a workstation (12) for inserting a terminal into a housing. The feed unit (14) includes a feed finger (56) for intermittently feeding the strip and an anti-backup finger (84) for preventing movement of the strip while the feed finger (56) is retracted preparatory to feeding the next terminal. A single release member (100) is arranged to pivot into first, second, and third positions (140, 142, 144) for moving the feed and anti-backup fingers into and out of engagement with the strip of terminals when loading the strip, when operating the insertion machine, and when removing the strip from the insertion machine, respectively.
