  • Patent number: 11597106
    Abstract: A terminal cutter includes a tool frame having a first cutting member coupled to an upper handle having a first cutting surface for cutting a terminal from a carrier strip and a second cutting member coupled to a lower handle having a second cutting surface for cutting the terminal from the carrier strip. A terminal strip guide assembly is coupled to the upper handle and/or the lower handle offset from the first and second cutting members. The terminal strip guide assembly includes a strip guide having a slot receiving the carrier strip and having a guide surface adjacent the slot. The guide surface is configured to engage the terminal to locate the terminal relative to the terminal strip guide assembly and to control a depth of the carrier strip received in the slot.

  • Patent number: 10847943
    Abstract: A 4-way indent tool includes a indenter actuator cam arm being movable between an unactuated position and an actuated position to actuate four indenters to crimp a terminal. The 4-way indent tool includes a drive assembly movable along the drive screw between a retracted position and an advanced position. The drive assembly has a drive nut on a drive screw and a coupler operably coupled between the drive nut and the indenter actuator cam arm. The coupler moves the indenter actuator cam arm. The coupler has a spring loaded coupling between the drive nut and the indenter actuator cam arm compressed as the coupler is moved between the retracted position and the advanced position.

  • Patent number: 10615557
    Abstract: A 4-way indent tool includes a cover holding a motor and a drive screw operably coupled to the motor and an indenter holder holding four indenters positioned orthogonally around a terminal opening configured to receive a terminal. The 4-way indent tool includes a indenter actuator cam arm positioned adjacent the indenter holder to operably engage the indenters having cam surfaces engaging the corresponding indenters to actuate the indenters. The 4-way indent tool includes a drive nut threadably coupled to the drive screw being moved linearly on the drive screw between an unactuated position and an actuated position. The indenter actuator cam arm is coupled to the drive nut and moves with the drive nut between the unactuated position and the actuated position to actuate the indenters.

  • Patent number: 8555933
    Abstract: A wire untwisting tool includes a housing having a wire gripping end, an actuation end and a cavity. A plunger is received in the cavity. The plunger is movable between a retracted position and an actuated position and includes a gripping head movable with the plunger between the retracted position and the actuated position. The gripping head is configured to hold the twisted pair of wires in the retracted position, wherein rotation of the housing in an untwisting direction untwists the wires. Optionally, the wire may be fixedly held remote from the gripping end, and the housing may be rotated about the location at which the wire is fixedly held.

  • Publication number: 20110235312
    Abstract: A crimping tool for crimping a terminal to a wire includes a tool head having a die assembly defining a crimping zone. The die assembly is configured to crimp the terminal to the wire in the crimping zone during a crimping operation. An actuator is coupled to the tool head and operatively coupled to the die assembly to actuate the die assembly during the crimping operation. A lighting assembly is coupled to the tool head. The lighting assembly illuminates the crimping zone.

  • Patent number: 5870925
    Abstract: A hand tool (10) is provided for crimping an electrical terminal onto a conductor. The tool includes a frame (12) having a fixed crimping tool (14) secured at one end and a movable crimping tool (16) arranged to slide along a linear path (20) within a guideway (48) in the frame (12) toward and away from the fixed crimping tool (14). A lever (18) is pivotally coupled to the movable crimping die (16) by a drive link (144) and three pivotal attachments (128, 146, 152). The drive link (144) includes a ratchet surface (188) in engagement with a pawl (196) pivotally attached to the lever (18) for compelling continued movement of the lever once a crimping operation has begun.

  • Patent number: 5839316
    Abstract: A hand-held crimping tool is disclosed having an air cylinder which retains thereto a head member, and has a moveable piston which is attached to a cam member. The cam member is receivable through the head member, and a crimping tool is fixed to the head member, whereby the cam member is cooperable with the crimping tool to move die surfaces towards one another for the crimping actuation of a wire terminal. The head member includes a pawl assembly, whereby the pawl member is cooperable with a ratchet surface provided on the cam member, whereby the cooperation of the ratchet and pawl determines the axial movement of the cam member relative to the head member, which also determines the crimping force exerted on the terminals to be crimped.
