An in-line portable, handheld hydraulic scissor-type action crimping tool having a handle assembly and a working head assembly is provided. The handle assembly has a tool frame portion and a neck portion. The working head assembly has a pair of jaw members joined so that they are movable relative to each other and held in place by a locking pin. One jaw member has a nest secured to or directly formed into the jaw member. The other jaw member has an indentor secured to or directly formed into the jaw member.

Portable, hand-held, battery operated, hydraulic tools are provided with a tool frame, a force sensor, and a location detector. A piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task, such as to apply a crimp to an electrical connector. The tool determines the maximum force applied to the crimp and records that maximum force along with the geographic location of the tool when the crimp was formed. The maximum force provides an indication of the quality of the crimp and the recorded location allows a potentially defective crimp to be located.

An assembly comprises a compression member configured to receive a force input from a compression tool and a frame including a cradle at one end, an end fitting at the other, and at least one structural member linking the cradle to the end fitting. The cradle is configured to engage one end of the connector and receives the prepared end of the coaxial cable. The end fitting is configured to detachably connect the frame to the compression tool and includes an aperture for receiving the force input from the compression tool. The structural member defines at least one surface configured to guide the compression member along the axis in response to the force input. The compression member imposes an axial force on the other end of the connector and is guided along the axis by the guide surface of the frame.

A hydraulically operated handheld device and a method of operating same are provided. The device includes a hydraulic pump, a moving part, a fixed part and a return valve with an associated valve seat. The moving part is moved into a working position due to the buildup of a hydraulic pressure by filling a hydraulic chamber with hydraulic medium from a reservoir with the aid of the hydraulic pump. The moving part can be automatically moved back from the working position into an end position upon reaching a predefined working pressure by opening the return valve. The hydraulic pressure acting upon the return valve is increased by a separately triggerable pressure increase, which results in opening of the return valve, in a hydraulic medium volume located upstream of the return valve in a flow direction of the hydraulic medium during the movement into the end position.

Embodiments of the invention provide a ram guide for a crimping tool. The crimping tool includes a crimping head and a ram head. The ram guide includes a track and slot. The ram guide is configured to guide the ram head within a crimp portion of the crimping head to axially align the ram head with the crimping head.

A working head for a hydraulic power tool including a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head configured to receive a first moveable die comprising a first body length. A second die head is adapted to receive a second die comprising a second body length. The first body length of the moveable die is different from the second body length of the stationary die.

Portable, hand-held hydraulic tools having a modular power unit within a handle assembly and a working head assembly mated to the handle assembly. The working head assembly can have a pair of movable jaws or a movable jaw and a fixed jaw. The jaws can be configured to perform different operating operations, such as crimping operations and cutting operations.

Systems and methods for reporting usage of a power tool. The power tool comprises a pair of jaws configured to crimp a workpiece, a piston cylinder configured to actuate at least one of the pair of jaws, and a sensor configured to sense operating characteristics associated with a crimping application. An electronic processor connected to the sensor. The electronic processor is configured to receive, from the sensor, one or more characteristic signals, determine, based on the one or more characteristic signals, a first operating characteristic of the power tool, and determine, based on the one or more characteristic signals, a second operating characteristic of the power tool. The electronic processor is configured to determine the crimping application of the power tool based on the first operating characteristic and the second operating characteristic and generate a report indicating the crimping application performed by the power tool.

Portable, hand-held, battery operated, hydraulic tools are provided with a tool frame, a force sensor, and a location detector. A piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task, such as to apply a crimp to an electrical connector. The tool determines the maximum force applied to the crimp and records that maximum force along with the geographic location of the tool when the crimp was formed. The maximum force provides an indication of the quality of the crimp and the recorded location allows a potentially defective crimp to be located.

A power tool system includes a hydraulic power tool. The hydraulic power tool includes a hydraulic drive, a sensor, and a first electronic processor. The sensor is configured to detect an operational parameter of the hydraulic drive during an operation by the hydraulic drive. The first electronic processor is configured to store a plurality of data points based on the operational parameter detected during the operation and send the plurality of data points to an external device. The external device includes a display screen and a second electronic processor configured to receive the plurality of data points from the hydraulic power tool, control the display screen to display an expected data point for the operational parameter for the operation, and control the display screen to display an actual data curve based on the plurality of data points, the actual data curve overlaid on the expected data point.
