A hydraulic pressing tool which is particularly suitable for pressing pipe fittings, and which has a hydraulic pump connected to an electric motor is provided. With the aid of the hydraulic pump, hydraulic fluid is pumped from a tank into a piston chamber to operate the hydraulic piston. The pressure prevailing in the piston chamber is determined by a pressure sensor. When a pressure limit is reached, a solenoid valve is opened by the control device such that the hydraulic fluid flows back out of the piston chamber, through the channels, and into a reservoir.

An electrical terminal applicator system includes a die connected to a press. A one-piece member including a stock guide portion is homogeneously connected to a tool receiving portion. The one-piece member is releasably secured to the die using a first fastener. A male member extends from the one-piece member, and a female slot is created in the die slidably receiving the male member to permit the one-piece member to be horizontally positioned on the die prior to securing the one-piece member using the single fastener. A tool assembly having a tool mount block is movable to a desired position. The tool assembly is releasably secured to the tool receiving portion using a second fastener after positioning the tool assembly in the desired position.

A pair of crimping pliers is provided. The crimping pliers include a large handle, a small handle, a connecting rod, and a clamp fixing plate that form a hinged four-rod mechanism. Two ends of the connecting rod are connected between a rear part of the large handle and a rear part of the small handle. The clamp fixing plate is connected between a front part of the large handle and a front part of the small handle. A rear part of the connecting rod is bent and extends towards a tail end of the large handle, thereby extending a force arm. A first returning spring is connected between a back side of a bent part of the clamp fixing plate and the large handle. A pawl is rotatable and installed at the large handle. The pawl matches and meshes with outer pawl teeth of the clamp fixing plate.

A universal compact compression tool includes a vise assembly having different sets of jaws. The different sets of jaws are for holding different connectors during installation on a cable. A shaft on the tool is mounted to move between advanced and retracted positions with respect to the vise assembly. On the shaft, a plunger is mounted to move between first and second positions. In the first position of the plunger, the plunger is advanced on the shaft. In the second position of the plunger, the plunger is retracted on the shaft. The user sets the plunger in either the first or the second position depending on the type of connector to be installed on the cable. Once selected, and with the connector in the vise assembly, the user closes a lever of the tool to move the shaft to the advanced position, thereby applying the connector to the cable.

An electrical terminal applicator system includes a die connected to a press. A one-piece member including a stock guide portion is homogeneously connected to a tool receiving portion. The one-piece member is releasably secured to the die using a first fastener. A male member extends from the one-piece member, and a female slot is created in the die slidably receiving the male member to permit the one-piece member to be horizontally positioned on the die prior to securing the one-piece member using the single fastener. A tool assembly having a tool mount block is movable to a desired position. The tool assembly is releasably secured to the tool receiving portion using a second fastener after positioning the tool assembly in the desired position.

Wire-stripping and crimping pliers twist a stranded cable end with bars projecting into a pliers mouth at free ends of pliers jaws and crimp a cable end region with a ferrule using a ram guided in a cassette in a pliers legs crossing region and running into a die due to a closing force upon pressing the legs together, to compress the ferrule in the die. First and second moldings on the jaws project into the mouth. A forced lock has a pawl and a toothed segment on the moldings preventing the pliers from opening without the ram previously running against the ferrule. The toothed segment on the first molding has a course corresponding to a movement curve of the jaws. The pawl on the second molding is movable by a spring but fixed in position. The first and/or second molding is formed in one piece with the bars.

A crimping tool is provided for crimping the tubular portion of a turned electrical contact concentrically about the bare end of an electrical conductor, including a tool body having a main first portion, and an integral coplanar second portion extending from the main body portion to define a first lever. A crimping die arrangement includes an annular stamp holder mounted opposite an opening contained in the tool body main first portion, and an annular thrust collar is mounted concentrically about the stamp holder for angular displacement between released and crimping positions, thereby to displace a plurality of stamp members radially of the stamp holder between released an crimping positions The thrust collar is angularly displaced between the released and crimping positions by a toggle link arrangement that connects a second lever both with the tool body main portion and with the thrust collar.

Pliers include a pair of arm members, a pair of handles, at least one interchangeable working jaw and a control mechanism. Each arm member includes two parallel arm plates. The handles are connected to each other for movement of the arm members towards and away from each other. The working jaw is detachably supported in between the arm plates of the associated arm member. The control mechanism includes a retaining spacer, a driving member and a spring biased between the retaining spacer and the driving member. The retaining spacer is positioned in between the arm plates of the arm member. The driving member is movably disposed in between the arm plates of the arm member and has an end knob exposed outside the arm member so that pressing of the end knob of the driving member drives the driving member to be engaged with or disengaged from the working jaw.

A crimping plier includes a clamp handle mechanism, a crimping mechanism, and a driving mechanism. The clamp handle mechanism includes a first clamp handle and a second clamp handle pivoted to each other. The crimping mechanism includes a main body, a crimping tooth member and a crimping member. One end of the crimping tooth member has a tooth-shaped structure, and the tooth-shaped structure corresponds to a terminal accommodation portion of the main body. The crimping member has a flat end positioned in a first position or a second position. The driving mechanism includes a first connecting rod and a second connecting rod respectively connected to the first clamp handle and the second clamp handle. The first connecting rod and the second connecting rod are jointly connected to the crimping tooth member and the crimping member.

A manually operated pressing tool has a first manual lever, a second manual lever, a node element pivotably connecting the two manual levers to one another via a first pivot axis and a second pivot axis and a crimping unit arranged on a head portion of the pressing tool. The crimping unit includes a crimping die and a die receptacle. The first and second manual levers are further coupled to one another via a fork element which has a fork neck, a first fork finger and a second fork finger. The fork neck is pivotably coupled to the first manual lever via a third pivot axis. The crimping die is arranged on the first fork finger and the die receptacle is arranged on a head portion of the first manual lever, The second fork finger is pivotably coupled to the second manual lever via a fourth pivot axis.
