A double crimping tool for fastening an electrical conductor with insulation to a contact element, which includes a front crimping unit with a front drive cam plate and front crimping stamps for forming a front press section in the region of the stripped end of the conductor; and a rear crimping unit with a rear drive cam plate and rear crimping stamps for forming a rear press section in the region of the insulation of the conductor. The crimping stamps are displaced by rotation of the drive cam plates. By levers the two drive cam plates are connected to a shared force introduction element such that during the pressing procedure at first optionally the front or the rear drive cam plate is rotated by a predefined initial pressing angle while the other drive cam plate is made to rotate only after the first drive cam plate has attained the initial pressing angle.

Double crimping tool

The invention relates to a pliers-type tool and to a method for cutting through optical fibre cables (OF). According to the invention, the OF cable is received between the jaws of the pliers precisely, in a specific position, and is securely and precisely held and supported there. The invention uses a novel round blade () which is accommodated in a separately operated cutting device (). A switching mechanism () is allocated to the cutting device for measuring the duration of use of the cutting blade.

Pliers-type tool and method for cutting through optical fibre cables

A crimping pliers has a movable plier leg coupled to a fixed plier leg and a curved body in a head part of the pliers. Movable crimping punches are located in a pivoting plunger which is enclosed in the curved body. An adjusting and setting device having a threaded bush, a threaded spindle, a setting wheel, a fine scale and a rough scale is located on the fixed plier leg. The adjusting and setting device pivots the curved body allowing precise adjustment of the crimping punches via control cams in the curved body.

Crimping pliers with adjustable crimping gauge

A crimping tool for crimping lead end sleeves, contact sockets, or plugs on the electrical conductors, two crimping jaws arranged in a tool head section for performing crimping, pivotably mounted and axially fixed in the tool head section, and forming a crimping aperature of adjustable cross-section, the crimping jaws on their outer peripheral surfaces receiving a pivot lever and are bringable into and out of a crimping position by a pivoting drive movement of the pivot lever, a toggle lever mechanism driven by the handles and effecting the pivoting drive movement of the pivot lever, for a force-stroke compensation between parts of a force transmission system, the crimping jaws in a region of their crimping profile being formed by a die surface and a sliding surface, the die surfaces of the crimping jaws forming a die profile of closed shape in all crimping position within an adjustable crimping range, the sliding surface of each of the crimping jaws being in planar contact with the die surface of an adjacent one of the crimping jaws, extending a plane of the adjacent die surface, the handles including a fixed handle formed as a compensating spring for force-stroke compensation between the parts of the force transmission system, and an elastic lever integrated and fixed in the fixed handle and mechanically linked with one lever arm of the toggle joint mechanism.

Crimping tool for crimping lead end sleeves and the like

A tool for crimping contact elements of electrical conductors and formed as pliers has main levers, pressing or mouth jaws which are formed on the main levers and closed in an effective region parallel, handles operative for bringing the pressing or mouth jaws to an opening position and also to a closing or pressing position, the both main levers which carry the pressing and mouth jaws being formed each as a one-arm lever which has an end opposite to the pressing and mouth jaws, a hinge pin turnably connecting the one-arm levers with one another at the ends, and an actuating lever associated with a movable main lever, formed as an angular lever and supported in an arm part of the immovable main lever, the actuating lever being drivingly connected with the movable main lever in a region of its pressing end mouth jaw via a lever element.

Tool for crimping contact elements

A hand crimping tool for crimping and notching of sleeve connectors, such as lead end sleeves and the like for electrical conductors has a head composed of flat part, a pressing unit arranged between the parts and composed of a relatively fixed pressing jaw and a pressing jaw which is movable relative to the fixed pressing jaw, both the pressing jaws being provided with a pressing profile, lateral cover plates which form the head and provides full-surface guiding and covering the pressing jaws, the cover plates extending approximately to a front end side of the head, at least one of the cover plates in a symmetry region of the pressing profile of the pressing jaws being provided laterally with a window-shape, forwardly open recess, the both pressing jaws in their laterally accessible regions having an acting profile with tooth tips which are removed by a predetermined value X and laterally open and accessible.
