Abstract: In a manually operated pliers-type tool comprising an elongated tool body with a part defining an operative section with two carrier means for operative means such as crimping die members, and a longitudinal operating lever, which is journalled to the tool body and together therewith defines a reverse handle arrangement, projects that part of the tool body and tool, which defines the operative section, in the direction from which the operating lever is attached to the tool body, and the operating lever terminates, in its folded-down position, before that projecting part, and is level therewith. In a preferred embodiment, one of the carrier means is embodied by at least one rocker which is pivotably mounted in the operative section with the aid of a resilient means, so that the respective operative means may recede to a certain degree under the effect of predetermined load.

Abstract: In a pliers-type tool with a fixed jaw carrier (13A) and a movable jaw carrier (13B) arranged on a pivotable rocker (14) which is connected with an at least to a limited degree resiliently bendable bracket (15). The rocker (14) is with the aid of a pivot pin (14A) pivotally attached to a longitudinal tool body (11), the pivot pin (14A) passing through the rocker (14) in a hole which is larger than the diameter of the pivot pin (14A), and is anchored on one end of a short link (17), the other end of which link is attached to the said bracket (17).Thus work pieces, having a size within certain limits, may be precisely treated.

Abstract: A contact element such as an end-sleeve or a cable shoe, having a connecting portion and a contact portion, is produced from an originally plane blank which has a substantially rectangular first part, which in the finished product defines said connecting portion, and a second part, which in the finished product defines said contact portion. A plurality of such blanks is joined into a metallic punching band with an obverse face and a reverse face and comprising a first zone with all the first parts of the blanks, and a second zone with all the second parts of blanks. On at least the obverse face of the first zone is an insulating cover or coating applied before the individual blanks are removed from the punching band, so that the contact elements having a metallic connection portion with an insulating layer are obtained.

Abstract: A pliers-type tool with two handles has a parallel mechanism carrying two carrier members for working jaws. The mechanism comprises two cross-wise arranged guide lever means and one of the carrier members or one of the guide lever means is merged with one of the handles to a rigid tool body. A resilient member may be interposed, also in tools not having a parallel mechanism, between a link connecting the two handles and a counter-element in order to compensate for inaccuracies and/or to enable an extra push at the end of a closing movement of the handles.

Abstract: A tool with two elongated handles and two jaws operatively connected to the handles is provided with a mechanism for preventing premature opening of the handles and jaws. The mechanism comprises a pawl operating as a bistable rocker and engaging, with one or with two engagement means, an engagement member defined by two projections delimitating an operational area, or by at least one row of teeth with which each of the two engagement means is alternately engageable, so as to prevent premature interruption of the closing movement and preferably also of the reverse opening movement of the handles and of the jaws.

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.
