Abstract: A stripping tool of a kind where first a local incision is made in the insulation layer or layers of an electrical conductor and then is extended along the entire cross-sectional periphery by relative rotation of the tool and of the conductor, is provided with a slider in a housing or tool body, which slider may be activated by an eccentric cam member so as to press the conductor against a cutting means. The cam member may be embodied by an annulus mounted on a bearing which has a central opening through which the user may slip on one finger of his hand in order to execute said rotation, and the cutting means may be defined by an exchangeable cassette provided with cutting blades settable by setting screws.

Abstract: In a pair of pliers where at least one of two shanks which carry jaws is built up of two spaced side-plates, is in at least one of the shanks a tapered section arranged rearwardly of a pivot point where the shank is attached to the other one. By the rearward location, which also allows a less steep taper, the tapered section is more spaced from the pivot point, whereby the danger of rupture upon heavy loading is diminished. Also the handles may be built up of spaced side-plates between which a stem portion of a protective grip with T-shaped cross-section is inserted.

Abstract: A locator device for a tool with crimping dies for cable shoes has at least one track for accommodating the contact portion of the cable shoe, a stationary stop at the end of the track and a movable stop at a selected location along the track. For treating cable shoes with longer contact portions, the movable stop is lifted from the track so that the stationary stop is operative, and when treating cable shoes with shorter contact portions the movable stop is put in place. The device is preferably made as a readily mountable accessory to the crimping tool.

Abstract: A tool for crimping cable shoe terminals having an affixing part and a contact part onto the ends of electrical conductors has a pair of jaws provided with at least one pair of co-operating crimping dies and hinged together by a pivot pin. On the same pivot pin is mounted a rocker arm carrying for each pair of crimping dies a chamber accommodating the contact part of a terminal to be crimped. The rocker arm is affected by a position-controlling force such as friction at the location of mounting, and by suitably located dog means so that it makes a move, after the crimping operation has been terminated, by which the terminal, now crimped on a conductor, is lifted from the crimping die so that it readily can be removed from the tool.

Abstract: A stripping device for coaxial cables comprises a handle member and a guiding track member for a predetermined end length of a cable, rotarily mounted in the handle member. Knife means, mounted in a knife holder which is pivotally attached to the guiding track member, are provided to perform at least two spaced incisions in the cable. A locking means connects temporarily an inserted cable non-rotarily with the handle member. By pivoting the knife holder towards the guiding track member and at the same time rotating the guiding track member with the attached knife holder about the cable locked in the handle member, a first incision is made and extended along the whole periphery of the cable by the knife means which is closest to the end of the knife holder remotest from the handle member.

Abstract: A mechanism for preventing premature opening of a tool having two elongate handles comprising a carrier having a row of teeth at one edge and a spring-affected, pivotable pawl co-operating with the row of teeth. The pawl operates as a bistable rocker swingable by end stops at both ends of the row of teeth from a first lateral position for engagement with the row through an instable middle position into a second engagement-free lateral position. The two ends of the spring affecting the pawl and a pivot pin on which the pawl is mounted lie along one straight line when the pawl passes through the instable middle position.

Abstract: A pair of tongs is on one side of the tool body provided with a rocker arms defining a two-armed lever. The forward arm portion of the rocker arms lies as a stop before die members provided in one of the jaws, and has an abutment edge over which the contact portion but not the affixing portion of a cable shoe inserted into the pair of tongs can pass. The rocker arm, affected by a spring, is with the aid of two actuating elements operated in such a way that in the final phase of a crimping operation the forward arm portion is totally removed from the area of the die members, thus enabling an elongation of the affixing portion of the respective cable shoe when being crimped.

Abstract: A hand-operated tool of the pliers type includes a body member in which a rectilinear guiding track for a jaw carrier is provided. One stationary jaw for treating a working piece is arranged at one end of the guiding track and another jaw on the jaw carrier. A handle is pivoted to the body member laterally of the guiding track and is provided with faces for engagement with co-operating faces on the jaw carrier so as to press the jaw carrier and the jaw mounted on it towards the stationary jaw when the handle is activated.

Abstract: A tool for removing insulation from electrical conductors includes an apparatus body, a knife head defining a separate unit and attachable to the body, and a support for a treated conductor located at one end of the head. At least one insulation-cutting knife is arranged in the support and a holder stirrup is provided to press the cable against the support and the knife or knives.

Abstract: In a pliers-type tool having a stationary first handle and a second handle pivotally movable relative to the first handle, a slidable jaw carrier is movable along a rectilinear guiding track in a body member due to the pivotal movement of the second handle. The first handle is fixed to the body member. The second handle is in engagement with a toggle mechanism including a driver arm which, in turn, is pivotally attached at a stationary location to the body member. When the second handle is pivoted, the driver arm contacts, in a gliding manner, the jaw carrier and moves it rectilinearly in the guiding track. The driver arm extends transversely of the rectilinear guiding direction of the guiding track. Forces acting through the driver arm in the direction transversely of the rectilinear direction of the guiding track are prevented from affecting the movement of the jaw carrier. The second handle can be connected to the first handle by a connecting link.

Abstract: Apparatus for separating individual conductor elements in a multiple-conductor flat ribbon cable including a rotatable cutting element for cutting the insulating sheathing of the cable along each of the score lines running between the individual conductor cores. The cutting element is provided with a plurality of protruding arcuate cutting edges each interrupted by a shorter indrawn non-cutting edge. Further provided is a cable support element adapted to press a cable inserted into the apparatus against the cutting edges, but not against the indrawn edges. When the indrawn edges face the cable support element, a feed-in and feed-out gap is provided for easy insertion and removal of the cable.

Abstract: Apparatus for stripping insulation from electrical conductors which have a circular cross-section includes a stationary stand on which a circular base plate is rotatably mounted. An elongated support unit for the conductor to be stripped is secured to and extends outwardly from the base plate. One or more insulation cutting knives are slidably or pivotally mounted on a mounting member which rotates together with the circular base plate. The number of knives depends on the type of conductor being stripped. Each knife is provided with an actuating device. The actuating device may be stationary or it may rotate at a rate slower than the rate at which the circular base plate rotates so that the associated knife gradually penetrates into and cuts the insulation layer on the conductor so that it can be stripped.

Abstract: A tool for removing insulation from cables includes a handle, a housing rotatably mounted in the handle, and a cutting blade mounted in and projecting out of the housing. A recess is formed in the surface of the housing from which the cutting blade projects. A holder stirrup positioned in the handle, holds the cable in position against the cutting blade.

Abstract: A hand tool for stripping insulation from the end of a wire includes a pair of gripping jaws for holding the wire and a pair of cutting and stripping jaws for removing the insulation. An actuating member is pivotally connected at one end to the cutting and stripping jaws and at the other end to a pivotally mounted driving member. When a pair of handles on the tools are pressed toward one another, the two pair of jaws engage the wire, one pair holding the wire while the other pair cuts and strips the insulation. During this operation, the actuating member displaces the cutting and stripping jaws away from the gripping jaws and pulls the cut insulation at least partly off the end of the wire.

Abstract: A tool particularly suitable for use in crimping includes two arm members and a pair of working jaws each supported on a different one of the arm members. A drive arrangement such as a pair of handles is connected to the arm members for moving the arm members relative to each other between open and closed positions. The drive arrangement, arm members and working jaws provide two force transmitting paths each extending between a different point on the drive arrangement where an external operating force is applied, and a different one of the working jaws whereat the operating force is transferred to an article to be worked on by the tool. At least one pivotal connection is provided, including at least one pivot member and a bearing member for engaging the pivot member. The bearing member is arranged to deform resiliently when the operating force is transferred to the bearing member by the pivot member.

Abstract: A crimping tool includes a pair of arm members and a driving mechanism such as a pair of handles for moving the arm members. An elongated working jaw is mounted on each of the arm members, one of the working jaws having a female die and the other working jaw having a male die arranged thereon. The female die has a notch, and the male die has a base part and an elongated leading face spaced from the base part. A locking mechanism prevents the driving mechanism from returning to an open position before the driving mechanism is brought to a fully closed position. A resilient elastomeric block is provided in the tool to enable the driving mechanism to be brought to the closed position when an article to be crimped is located between the working jaws.

Abstract: A tool such as a pair of pliers, designed to handle cables, rods and similar workpieces of generally circular cross-section, has two coacting jaws swingably linked via respective shanks with operating means such as a pair of handles. The two shanks are limitedly relatively rotatable about a pivotal axis paralleling the swing axes of the jaws, each jaw comprising an elongate base with upstanding parallel webs transverse to the swing plane having workpiece-engaging faces alternately inclined in opposite directions with reference to that plane so as to form a channel around the workpiece in a working position. The relative motion of the shanks can be limited by an abutment or a link to establish a position of maximum jaw separation in which at least the webs closest to the pivotal axis still interengage to insure proper interfitting of all the webs upon the next return to the working position.

Abstract: A tool for removing solder comprises a tubular body having a nozzle at one end thereof and a piston device arranged to reciprocate within the tubular body to produce a suction effect through the nozzle during a solder removing operation. The piston device includes a piston rod and a piston member slidably mounted on the rod with a spring operating to urge the piston member relative to the rod in a direction toward the nozzle and with a stop member limiting movement of the piston member in this direction.

Abstract: A tool such as a vise or a pair of pliers has two relatively movable jaws linked via respective shanks with operating means such as a pair of handles, each jaw comprising an elongate base with upstanding parallel webs having workpiece-engaging faces alternately inclined in opposite directions. To facilitate the interfitting of these webs in a working position, particularly with pivotally interconnected shanks whose pivotal axis parallels the planes of the webs, the jaws are swingably mounted on their shanks with swing axes parallel to the pivotal axis. One shank is connected to its handle by way of an interposed resilient pad of adjustable elasticity.

Abstract: A wire stripper for removing the insulation from single-core or coaxial cable has a pair of elongated jaws which are hinged together at one end and are provided with a latch at the other end so that they can clamp the wire between them. One of the jaws carries a blade, preferably in a replaceable cartridge, adapted to penetrate into part of the periphery of the insulation of the wire while the other jaw is formed with a bed to receive the wire and hold it during penetration by the blade. One of the jaws is also provided with a ring or eye into which the user can insert a finger and thereby twirl the tool around to effect relative rotation of the tool and the wire to cut through the insulation over its entire circumference. The tool is then drawn off the wire axially or the wire is withdrawn axially from the tool to strip the severed length of insulation from the wire. When two axially spaced cuts are to be made, the replaceable cartridge is formed with two blades in parallel transversely spaced relation.
