The pliers tool is in particular a crimping tool. By means of a crimping tool can be done by manual operation of hand levers pressing or crimping a workpiece. Here, a crimping tool is used in particular to produce a permanent mechanical connection and electrical contacting. This is preferably done by crimping a plug with a cable or an electrical conductor of any type. Depending on the profile of the dies used, different crimping processes can be carried out with the crimping tool. For example, it may be a closed crimp in which the conductor is inserted into a closed crimping zone of a plug or into a closed sleeve and crimped by plastic deformation of the crimping zone or sleeve. But it is also possible that an open crimp is generated, in which the plug has an open crimping zone, in which the conductor can be inserted from above.

In recent years, manual pliers tools have been increasingly equipped with electronic assemblies, by means of which additional functions (such as monitoring a forceps or crimping force, a power stroke of jaws or an assessment of performing a job with the pliers tool) to be provided.

The invention also encompasses a pair of pliers tools in which an actuating force applied to a hand lever by a user's hand is assisted or reinforced by a drive, in particular an electric drive, so that the forceps or crimping force from the sum of the actuating force and the force of a drive (possibly with translation of the actuating force and / or the force of the drive by a drive mechanism) results. In this case, the amount of forceps or crimping force and / or the force of the drive is controlled by the actuating force applied by the user.

STATE OF THE ART

The website www.rennsteig.com offers a four-mandrel crimping tool with the "MicroCrimp" marking, which is intended to crimp rotated pin or book contacts. A delivery of the crimping mandrels is adjustable in increments of 0.01 mm. A check of the basic setting can be done by means of a gauge. A variant of this four-mandrel crimping tool is offered under the designation "DigiCrimp". This version has an electronics module that allows electronic wear monitoring with a warning function and the retrieval of different adjustment functions. In order to enable the recording of the electrical and electronic components of the electronic assembly between cover plates of a fixed pliers part of the four-mandrel crimping tool, the cover plates are opposite to the marked with the "MicroCrimp" variant of the four-mandrel crimping tool on the side facing away from the hand levers of the mandrels and extended the recording for the workpiece. In the region of the extension, a cover plate has a window-like recess in which a digital display is arranged. A corresponding embodiment is in the patent EP 2 313 235 B1 described.

SOLUTION

The object of the invention is achieved with the features of the independent claim. Further preferred embodiments according to the invention can be found in the dependent claims.

DESCRIPTION OF THE INVENTION

The invention relates to a manual pliers tool which can be actuated by a user by applying manual hand forces. The manual pincer tool has a mechanical pincer part by means of which the mechanical functions of the pincer tool are provided. The mechanical pliers part has two pivotable hand lever and two relatively movable (in particular pivotable or translationally movable to each other) jaws. The hand lever and the jaws are coupled to each other via a drive mechanism, which may also have a gear ratio and, for example. Based on a toggle lever drive. Thus, by a caused by the user pivoting the lever, the jaws can be moved over a working stroke. The machining of the workpiece then takes place in the working stroke. For the formation of the pliers tool as a crimping tool, a crimping of the workpiece takes place via the working stroke, which takes place by means of dies formed or carried by the pliers jaws. The use of the invention is not limited to a specific drive mechanism with respect to the specific embodiment of the mechanical pliers part. To name but a few non-limiting examples of the invention, the drive mechanism according to the non-prepublished European patent application EP 18 166 739.5 or according to the pamphlets DE 10 2008 005 472 B3 . DE 40 23 337 C1 . DE 40 26 332 C2 . DE 197 13 580 C2 . DE 197 53 436 C2 . DE 198 07 737 C2 . DE 10 2005 003 615 B3 . DE 20 2008 003 703 U1 may be formed, then according to these embodiments, the degrees of freedom of the jaws can be designed and the arrangement of the jaws and hand lever can be done relative to each other and in the case of the formation of the pliers tool as a multi-mandrel crimping tool as a "jaw" also relatively twisted actuation rings or actuation discs can be viewed.

The invention initially proposes that the electronic assembly is formed independently of the mechanical pliers part. This means that the mechanical function of the pliers tool can also be provided if the electronics assembly is not present. This has, for example, the consequence that it is possible that a pair of pliers tool can be produced in two variants, wherein a variant of the pliers tool is equipped without electronics assembly, while the other variant is equipped with electronics assembly. For both variants then the same mechanical pliers part can be used.

Under certain circumstances, the formation of the electronic assembly separately from the mechanical pliers part also leads to a simplification of manufacture and / or assembly, since the mechanical pliers part on the one hand and the electronics module can be manufactured at different manufacturing sites and possibly also pre-assembled and / or can be made of different materials.

Furthermore, the invention proposes that an arrangement of the electronic assembly takes place in a special area of the pliers tool: According to the invention, the electronic assembly is arranged in a pliers head part of the mechanical pliers part. This pliers head part is the part of the pliers head, which is arranged between the hand levers and the jaws. In the region of this pliers head part may be at least a part of the drive mechanism with drive elements such as a toggle lever drive. If the pliers head part has a housing or cover plates, the housing or the cover plates are suitable for fastening the electronics module to the pliers head part and thus to the pliers tool.

The embodiment of the invention thus utilizes the already existing pliers head part, which results in a compact design of the pliers tool. On the other hand, the embodiment according to the invention is based on the finding that an extension of the pliers head beyond the receptacle for the workpiece and the pliers jaws, as is done for the product "DigiCrimp" explained above, is disadvantageous not only in terms of the size of the pliers tool: For such Arrangement of the electronic unit is just enlarged the pliers head of the pliers tool, which makes the insertion of the pliers tool in confined spaces, in the area which, for example, a manufacture of a Leitercrimps required difficult or even impossible.

In the context of the invention, the electronic assembly is attached directly to the pliers head part, which u by any attachment options, in particular screwing, gluing, latching, locking u. Ä., Can be done.

In the context of the invention, the electronic assembly can be equipped with any electrical and electronic components, cf. this also includes electronic assemblies according to the prior art. For a further embodiment of the pliers tool according to the invention, the electronic assembly has an electronic control unit, which can also be understood as a plurality of interconnected sub-control units. To name just an example, the control unit can be a "NXP Kinetis KW41Z, ARM Cortex-MO +, 48 MHz" CPU, the CPU also having a memory (in particular with up to 512 kB of flash memory) and up to 128 kB SRAM). Alternatively or additionally, it is possible for the electronic component to have an input element. There are many possibilities for the design of such an input element. Thus, the input element may serve to directly input a desire or signal of the user. In this case, the input element may, for example, be a switch, a rotary knob or even a keyboard. But it is also possible that an input element for communication with neighboring components in the electronics module is present. Thus, for example, the input element can be a wired interface (for example a USB interface) or a wireless interface (for example WLAN or Bluetooth). Accordingly, a wireless or wired output element can be present, via which then (wireless or wired), the electronic assembly with an external device for transmission of manual specifications by the user and / or output of operating variables, measurements or other signals by the electronics Unit can communicate. Alternatively or additionally, it is possible that the electronic component has a display element, in particular a (single-line or multi-line) display. Alternatively or additionally, it is possible for the electronic component to have a luminaire which, for example, can be used as an indicator for an operating state, as an indication of an improper working process, as a signal device for a state of charge of a battery or the like. Such a luminaire may, for example, be an LED in any desired color or else an RBG LED. But it is also possible that the lamp is used to illuminate a component of the pliers tool, in particular a locator or the receptacle for the workpiece and / or the environment of the pliers tool in the manner of a flashlight. Finally, it is also possible that a basic lighting of the pliers tool takes place on the light to this visually visible to signal, for example, in darkened rooms or a tool box and / or to signal via the lamp a readiness for operation of the pliers tool or the electronic module. Alternatively or additionally, it is possible for the electronic component to have an acoustic output element. The acoustic output element can be used to communicate with the user in order, for example, to signal operational readiness, to signal complete passage of a power stroke with the achievement of the end position of the jaws, a signal regarding the evaluation of measured force force profiles and / or measured deflections of the jaws and jaws / or to signal from courses of the same. Alternatively or cumulatively, it is possible for the electronic component to have a sensor. Such a sensor may, for example, be an acceleration sensor. For purposes of example only, an example of the invention, the acceleration sensor may be a NXP sensor "MMA8652FC". About such an acceleration sensor can be distinguished whether the pliers tool is stored or moved in the hand of a user. If a recording of the pliers tool detected by a detected after prolonged rest acceleration occurring above the acceleration sensor, a "waking" of the electronic assembly can be done by a change from a power consumption optimized standby state is in a standby mode. To mention only other, non-limiting examples of the embodiment of a sensor, it may be the sensor to a force sensor, via which a forceps force or crimping force is measured, or a displacement sensor, which the working stroke of the jaws or any Drive element of the drive mechanism detected. It is possible that for wireless communication with the pliers tool a 2.4 GHz wireless technology according to the standard IEEE 802.15.4 is used, whereby a technique "Bluetooth Low Energy 4.2" can be used. It is possible that the sensor is a counter, which may be designed in particular as an IR proximity sensor, which is marketed under the "AMS TCS 73327". For example, an OLED display can be used as the display element, here for example a product which is marketed under the designation "VGM 096064 A5W01 and has a white monochrome resolution of 96 × 64 pixels , in the region of which the electronics assembly is arranged, has a rectangular cross-section, in which opposite sides are formed by cover plates of the pliers head, the electronic assembly may extend in a partial region of a page in the cross section, "one corner" in the Area of two sides of the rectangle around the mechanical pliers part or, for example, U-shaped around two corners three adjacent sides of the rectangle. It is also possible that the electronic component has subunits which are arranged in the region of one side of the rectangular cross section or are attached to this cross section in the region of different sides of the rectangular cross section. For a particular embodiment of the invention, the electronic assembly extends on two opposite sides of the pliers head part, wherein these opposite sides in the above-described rectangular cross section of the mechanical pliers part is the longer sides of the rectangle, which of the cover plates of the mechanical pliers part can be trained. This embodiment has the advantage that, on the one hand, a good fastening of the electronic component, in particular on the said cover plates of the pliers head, is ensured. On the other hand, the pliers head part in the region of these opposite sides has an enlarged extent, so that a larger number of components of the electronic assembly or larger such components can be arranged in the region of these pages.

It is possible for a particular proposal of the invention that the electronic assembly has a continuous edge-closed recess. Through the edge-closed recess then extends the mechanical pliers part. In other words, the electronic package for this embodiment extends circumferentially around the mechanical pliers part throughout. It is possible, for example, that for this embodiment, the electronic assembly is formed as a kind of ring. Due to the continuous edge-closed recess, the electronics assembly has a front opening and a rear opening. In the area of the front opening, the forceps jaws extend out of the electronics unit, while the hand levers extend out of the rear opening of the edge-closed recess of the electronic unit. But it is also possible that the jaws or the hand lever of the associated opening are located upstream or downstream, in which case a drive element of the drive mechanism or a housing of the pliers head can extend out of the opening.

For the choice of the material of the housing of the electronic module and the configuration of the same there are many possibilities within the scope of the invention. For example, the housing may be made with any number of housing parts made of plastic. For a proposal of the invention, the housing of the electronic assembly on two half-shell-like housing parts. The two half-shell-like housing parts are closed in a mounted state in the circumferential direction, whereby they form a kind of ring. The two Housing parts then extend in the assembled state around the mechanical pliers part. The mechanical pliers part is then arranged on the inside of these two shell-like housing parts, so that an interior of the electronics module, in which the components of the electronics assembly are accommodated, is bounded on the outside by the two half-shell-like housing parts, while this interior is then internally supported by the mechanical housing Pliers part, especially with cover plates, is limited. Preferably, the two half-shell-like housing parts close tightly inside and possibly even under sealing to the mechanical pliers part. The connection of the two housing parts can be done arbitrarily within the scope of the invention with each other and / or with the mechanical pliers part. Thus, for example, it is possible that the two housing parts are clipped together, glued, latched, locked, pressed and / or screwed together and / or with the mechanical pliers part.

It is also possible that the housing of the electronic module has a housing part, which forms an end face of the electronic module facing the jaws. For a particular proposal of the invention, the housing of the electronic assembly is formed in three parts with the two aforementioned half-shell-like housing parts and a further housing part, which forms the jaws facing the end face of the electronic module.

For a further development of this latter embodiment, the two half-shell-like housing parts form a form-locking with one another, which is produced with a joining direction, which is oriented vertically to a longitudinal axis of the pliers tool. In principle, the half-shell-like housing parts joined together in this way could be loosened if they are acted upon by forces counter to the joining direction vertically to the longitudinal axis of the tong tool. The further housing part, which forms an end face of the electronic module facing the jaws, can in this case form a positive connection with the half-shell-like housing parts, a joining direction being used for this positive connection, which is oriented in the direction of a longitudinal axis of the tong tool. The such form-fitting connection of the further housing part with the two half-shell-like housing parts mounted together ensures that a loosening of the two half-shell-like housing parts is at least difficult, as this requires a movement of the half-shell-like housing parts vertically to the longitudinal axis of the pliers tool, which is prevented by the other housing part ,

For the basic geometry of the housing of the electronic module, there are many possibilities within the scope of the invention. For a proposal of the invention, the housing of the electronic assembly is V-shaped in a plan view of a pliers head plane on the hand levers facing front side, wherein the connection region of the two legs of the V can also be rounded or flattened. In this case, the hand levers each come out of the housing from one leg of the V. This results in a particularly compact embodiment, in which the connecting region of the legs of the V can extend into the intermediate space formed between the two hand levers.

Within the scope of the invention, the electronic component can have at least one printed circuit board which carries the electrical and electronic components of the electronics module and / or an electronic control unit. For a proposal of the invention, a circuit board is arranged in each case on one side of the pliers head part. It is possible here that the boards are bolted to the housing parts, so that they do not have to be connected to the mechanical pliers part. In the simplest case, all components of the electronics assembly are attached to the housing, which in turn is then attached to the mechanical pliers part.

For the use of two arranged on opposite sides of the pliers headboard boards, the two boards can be connected to each other via a cable. In this case, it is possible that the cable extends through a recess of the mechanical pliers part. For a further proposal of the invention, however, the two boards are connected to each other via a cable which extends in the circumferential direction around the mechanical pliers part of the one board to the other board. For the aforementioned example, according to which the mechanical pliers part in the region of the electronic component has a rectangular cross-section whose longer sides are formed by cover plates, the two boards are each arranged in the region of an outer side of a cover plate and the cable then extends from these longer sides of the rectangular cross section around the corners of the rectangle and along a shorter side of the rectangular cross section from one board to the other board. The cable may, for example, be a flexible ribbon cable. The cable extends in this case in an annular interior, which is bounded on the inside of the mechanical pliers part and on the outside of a housing of the electronic component.

For an embodiment of the pliers tool according to the invention, the housing of the electronic component has a light-permeable or partially transparent portion. For example, this portion of the further housing part can be formed, which forms the forceps jaws facing the front side of the electronic component. For this embodiment, a lamp is arranged in the interior of the housing of the electronic module. This luminaire is arranged and aligned such that light emitted by the luminaire acts on the permeable or partially transparent portion. If the subregion is permeable, illumination of the surrounding region of the electronic subassembly, that is, for example, a locator of a crimping tool or a receptacle for the workpiece, can take place by means of the luminaire. It is also possible that the light of the lamp passes through the permeable portion and allows use in the manner of a flashlight function, over which an environment of the pliers tool can be illuminated. On the other hand, if the light emitted by the luminaire drifts onto a partially transmissive partial region, in the region of which a reflection also takes place, a backlighting of the partial region can take place, whereby, for example, a type of colored ring can be produced on the electronic component. Depending on the lighting, different operating states of the electronic module can be made visible via this backlit part. For example, it can be signaled via a flashing subarea that contact is attempted via a wireless connection, while it can be signaled with permanent backlighting that contact has been established via the wireless connection. Alternatively or additionally, it is possible that the backlighting of the subarea, possibly with a different color, signals that the electronic subassembly is ready for operation. With regard to further possibilities of using the light emitted by the lamp, the orientation of the lamp and the integration in the pliers tool is exemplified in the publications US 2011/0235312 A1 such as EP 3 312 949 A1 directed.

It is entirely possible that the electronic assembly is supplied with electrical energy via a cable that can be connected to the pliers tool. Preferably, however, the electronic assembly is powered by a battery or an accumulator with electrical energy. A battery or a rechargeable battery, in particular a button cell, can for example be integrated into the electronics module. For another proposal of the invention, the battery or the accumulator is integrated in a hand lever, so that the battery or the accumulator is formed and arranged separately from the electronic assembly and is connected thereto via an electrical supply cable. This embodiment of the invention utilizes the available space in the area of the hand lever anyway.

For a particular embodiment, the hand lever on a metallic hand lever strut. To this metallic hand lever strut extends a handle made of plastic. In this case, a gap is formed between the handle and the hand lever strut, and the battery or the accumulator is disposed in the space. In this case, a receptacle for the battery or the accumulator, for example, be held on the hand lever strut.

Another proposal of the invention is dedicated to detecting a movement of the drive mechanism and thus the movement of the jaws. It is proposed that the drive mechanism has a drive element which is arranged on the mechanical pliers part. To mention only an example, not limiting the invention, it may be a pressure lever of a pliers tool, which according to the non-prepublished European patent application EP 18 166 739.5 is formed and wherein the pressure lever is arranged outside of cover plates of the pliers head. This drive element is moved (possibly with a small distance) relative to a sensor of the electronic component. The sensor can then detect the movement of the drive element and thus the drive mechanism and the jaws. In this case, the sensor can detect a path. But it is also possible that the sensor merely signals a changeover for the achievement of a predetermined partial stroke of the working stroke, for example the exceeding of 15% of the working stroke or the reaching of the closed position. For example, for this purpose, a sensor of the type "IR proximity sensor" with a counter can be used (cf the commercially sold product AMS TCS 73327 ").

If the mechanical pliers part has cover plates in the region of the pliers head, between which pliers jaws and / or drive elements of the drive mechanism are arranged, the intermediate space formed between the cover plates can be open to the outside, which can not be visually appealing and also the entry of objects or contaminants May have consequences. It is also possible that access to the electronic module can be created via this gap, which can be undesirable. In order to avoid this, the invention proposes that the mechanical pliers part has a cover element in the region of the pliers head. The cover element closes a gap formed between the cover plates to the outside over at least a partial circumference of the pliers head, which is preferably the case in the peripheral area adjacent to the electronics module and / or in the interior of the electronics module. To only one the invention As a non-limiting example, the cover member may have a T-shaped cross-section. Here, the length of the upper transverse leg of the T corresponds to the distance of the cover plates. The upper transverse leg of the T thus abuts the end faces of the cover plates and closes the gap. The vertical leg of the T can enter the intermediate space and, for example, be pressed or clipped into the intermediate space or the cover plates delimiting the intermediate space in a form-fitting and / or frictional engagement.

• Möglich ist, dass mittels der Steuerlogik der elektronischen Steuereinheit eine Auswertung eines Ladezustands einer Batterie oder eines Akkumulators erfolgt. Möglich ist bspw., dass bei Erkennung eines niedrigen Ladezustands eine Anzeige über eine LED oder ein Display erfolgt. Möglich ist auch, dass bei Unterschreitung eines Schwellwerts eines Ladezustands der Batterie ein Energiesparmodus aktiviert wird, bei welchem bspw. eine Leuchte oder ein Display gedimmt wird oder sogar deaktiviert wird.
• Möglich ist, dass die Steuerlogik der elektronischen Steuereinheit eine von einem Sensor ermittelte Zangenbackenkraft oder einen Zangenbackenweg (bzw. eines damit korrelierenden Wegs einer Komponente des Antriebsmechanismus) auswertet, was unter Berücksichtigung eines Kalibrierfaktors, einer Speicherung für eine spätere weitere Verarbeitung, einen Vergleich mit einem Schwellwert, einen Vergleich mit einer Sollkurve u. ä erfolgen kann.
• Möglich ist, dass die Steuerlogik der elektronischen Steuereinheit die Zahl von durchlaufenden Arbeitshüben ermittelt, wobei es sich bspw. um insgesamt von dem Zangenwerkzeug seit der Herstellung oder einer letzten Wartung durchlaufende Arbeitshübe oder die an einem Tag oder innerhalb einer vorbestimmten Periode durchlaufenden Arbeitshübe handeln kann. Möglich ist, dass die Zahl der durchlaufenden Arbeitshübe mit einem Schwellwert verglichen wird, wobei dann mit Überschreiten des Schwellwerts dem Benutzer signalisiert werden kann, dass das Zangenwerkzeug unmittelbar oder nach einer gewissen Zahl von weiteren Arbeitshüben gewartet werden muss oder sogar unbrauchbar wird. Denkbar ist auch, dass mit Überschreiten einer Vorgabe für die maximal durchlaufenden Arbeitshübe eine Deaktivierung des Zangenwerkzeugs von der elektronischen Steuereinheit herbeigeführt wird, was bspw. mittels einer Verriegelung der bewegten Teile des Zangenwerkzeugs erfolgen kann oder dem Lösen einer in den Antriebsmechanismus integrierten Kupplung. Hinsichtlich weiterer Details zur Ermittlung und Auswertung einer Zahl von durchlaufenden Arbeitshüben wird beispielhaft auf die europäische Patentanmeldung EP 2 995 424 A1 verwiesen.
• Möglich ist auch, dass die Steuerlogik der elektronischen Steuereinheit eine Bewertung eines mit dem Zangenwerkzeug durchgeführten Bearbeitungsvorgangs vornimmt. Diese Bewertung kann beispielsweise dadurch erfolgen, dass eine erfasste Zangenkraft (bspw. ein Maximum der Crimpkraft oder die Crimpkraft für das Erreichen eines vorgegebenen Teilhubs des Arbeitshubs) innerhalb eines vorgegebenen Bereichs der Zangenkraft liegt oder ein Verlauf der Zangenkraft innerhalb vorgegebener Toleranzen für einen idealen Verlauf der Zangenkraft liegt.
• Möglich ist, dass die Steuerlogik der elektronischen Steuereinheit eine Speicherung von Daten vornimmt, insbesondere die Zahl der durchlaufenden Arbeitshübe, diskrete Werte oder Verläufe der Zangenkraft und/oder des Weges der Zangenbacken u. ä. Die derart gespeicherten Daten können dann später ausgelesen werden und zur Dokumentation des mit dem Zangenwerkzeug erzeugten Arbeitsergebnisses verwendet werden.
• Die Erfindung umfasst auch Ausführungsformen, bei welcher Daten gespeichert werden wie bspw. die Zahl der durchlaufenden Arbeitshübe, wobei ein Auslesen der derart gespeicherten Daten aber lediglich durch den Hersteller erfolgen kann, womit der Hersteller auf Grundlage dieser Daten dann eine Beurteilung eines etwaigen Versagens des Zangenwerkzeugs vornehmen kann.
• Möglich ist, dass durch die Steuerlogik der elektronischen Steuereinheit ein Energiemanagement derart erfolgt, dass vermieden wird, dass die Elektronik-Baueinheit zu viel elektrische Energie verbraucht, wenn das Zangenwerkzeug überhaupt nicht genutzt wird und bspw. in einer Werkzeugkiste oder auf einem Tisch ruht. Für diese Ausgestaltung nimmt das Zangenwerkzeug grundsätzlich einen Standby-Modus ein, in welchem die elektrische Leistungsaufnahme minimiert wird. In diesem Fall wird dennoch in dem Standby-Modus ein Signal eines Beschleunigungssensors derart ausgewertet, dass eine Bewegung des Zangenwerkzeugs erkannt wird insbesondere durch eine auftretende gemessene Beschleunigung. Wird eine derartige Bewegung des Zangenwerkzeugs durch die Aufnahme des Zangenwerkzeugs durch den Benutzer erkannt, aktiviert die Steuerlogik der elektronischen Steuereinheit einen Bereitschaftsmodus, so dass der Standby-Modus verlassen wird. In dem Bereitschaftsmodus kann dann eine erweiterte Funktionalität der Elektronik-Baueinheit gewährleistet werden, so dass die Elektronik-Baueinheit "aufgeweckt" wird. Für eine Ausgestaltung der Erfindung wird in dem Bereitschaftsmodus bspw. über einen Sensor erfasst, ob eine Betätigung des Zangenwerkzeugs erfolgt. Der Sensor kann bspw. erfassen, ob ein Durchlaufen des Arbeitshubs erfolgt, was über einen Wegsensor oder einen Endlagenschalter erfolgen kann. Eine derartige Überwachung, ob eine Betätigung des Zangenwerkzeugs erfolgt, kann bspw. für einen vorgegebenen Zeitraum (insbesondere 10 Sekunden) nach dem Wechsel in den Bereitschaftsmodus erfolgen. Erfolgt innerhalb dieses Zeitraums keine Betätigung des Zangenwerkzeugs, erfolgt eine automatische Rückkehr in den Standby-Modus. Auch möglich ist, dass eine Rückkehr in den Standby-Modus durch die Steuerlogik herbeigeführt wird, wenn nach Aktivierung des Bereitschaftsmodus über den Beschleunigungssensor erkannt wird, dass sich das Zangenwerkzeug für eine vorgegebene Zeitspanne in einem Ruhezustand ohne auftretende Bewegung befindet.
• Möglich ist, dass für den Fall, dass (ggf. nach einem Wechsel von dem Standby-Modus in den Bereitschaftsmodus wie zuvor erläutert) eine Betätigung des Zangenwerkzeugs über einen Sensor erfasst wird, mittels der Steuerlogik der elektronischen Steuereinheit ein Display und/oder eine Leuchte aktiviert wird. Für die Leuchte kann bspw. dem Benutzer die Betriebsbereitschaft des Zangenwerkzeugs signalisiert werden. Des Weiteren kann mittels der Aktivierung des Displays die Anzeige der für den Benutzer relevanten Informationen an dem Display initiiert werden.
• Wird mittels der Steuerlogik erfasst, dass für eine vorgegebene erste Zeitspanne keine Betätigung des Zangenwerkzeugs erfolgt ist oder aber für eine vorgegebene zweite Zeitspanne keine Bewegung des Zangenwerkzeugs erfolgt ist, kann ein Display und/oder eine Leuchte deaktiviert werden. Für diese Ausgestaltung ist vorzugsweise die erste Zeitspanne länger als die zweite Zeitspanne.
• Die Steuerlogik der elektronischen Steuereinheit kann zuständig sein für das Betreiben einer drahtlosen Sende- und/oder Empfangseinrichtung. Über die Empfangseinrichtung kann bspw. eine Konfiguration des Zangenwerkzeugs und/oder der Elektronik-Baueinheit erfolgen. Hingegen kann über die drahtlose Sendeeinrichtung bspw. ein Übertragen von Daten hinsichtlich des durchgeführten Arbeitsprozesses an eine externe Auswerteeinrichtung erfolgen.
• Möglich ist, dass die Steuerlogik der elektronischen Steuereinheit eine Ansteuerung mindestens einer Leuchte (bspw. einer LED) vornimmt. Diese Ansteuerung kann in dem Aktivieren und Deaktivieren der Leuchte, der Veränderung der Farbe der Leuchte, dem Wechsel von einem permanenten zu einem blinkenden Betrieb der Leuchte u. ä. bestehen.
• Möglich ist, dass die Steuerlogik der elektronischen Steuereinheit eine Leuchte oder eine Anzeige dimmt, wenn erkannt wird, dass ein Ladezustand einer Batterie oder eines Akkumulators einen Schwellwert unterschreitet, wodurch der Energieverbrauch des Zangenwerkzeugs reduziert wird.
• Möglich ist, dass die Steuerlogik der elektronischen Steuereinheit die Vorgabe eines Tasters, der von einem Benutzer betätigt werden kann, auswertet, indem bei einem Betätigen des Tasters für eine erste Zeitspanne eine Leuchte aktiviert wird, während bei einem Betätigen des Tasters für eine zweite Zeitspanne eine drahtlose Verbindung aktiviert wird. So kann bspw. bei einem Betätigen des Tasters für die erste Zeitspanne die Leuchte aktiviert werden, um die Beleuchtung der Umgebung des Zangenwerkzeugs, also eine Funktion ähnlich einer Taschenlampe, zu aktivieren, während für die Betätigung des Tasters für die zweite Zeitspanne ein Verbindungsaufbau (bspw. über Bluetooths) ermöglicht wird.
• Möglich ist, dass die Steuerlogik eine (Um-Konfiguration) des Zangenwerkzeugs ermöglicht, was mittels einer drahtlosen oder kabelgebundenen Kommunikation erfolgen kann oder sogar durch direkte Eingabe an einem Eingabefeld des Zangenwerkzeugs. Um lediglich einige die Erfindung nicht beschränkende Beispiele zu nennen, kann die Konfiguration darin bestehen, dass ein Name des Benutzers oder des Unternehmens, in welchem das Zangenwerkzeug verwendet wird, oder ein Name oder eine Kennzeichnung des Herstellers auf das Zangenwerkzeug "aufgespielt" wird. Möglich ist aber auch, dass die Konfiguration darin besteht, dass Kalibrierfaktoren für in dem Zangenwerkzeug eingesetzte Sensoren übermittelt werden oder auch dem Zangenwerkzeug zur Kenntnis gebracht wird, welche Art von Werkstück mit dem Zangenwerkzeug bearbeitet werden soll, wobei dann unter Umständen auch unterschiedliche Betriebsweisen des Zangenwerkzeugs von der Steuerlogik ausgesteuert werden können.

Dies kann bspw. durch einen Kontakt im Bereich der Aufnahme des Zangenwerkzeugs für das Werkstück erfolgen. Je nach Kontaktkraft oder Betätigen des Kontakts kann dann mittels der Steuerlogik darauf geschlossen werden, ob das Werkstück korrekt in die Aufnahme eingelegt worden ist oder nicht.

A further embodiment of the invention has the guarantee of further functions by a control logic of the electronic control unit to the subject:

• It is possible that by means of the control logic of the electronic control unit, an evaluation of a state of charge of a battery or a rechargeable battery takes place. It is possible, for example, that when a low state of charge is detected, an indication is made via an LED or a display. It is also possible that falls below a threshold value of a state of charge of the battery, an energy saving mode is activated, in which, for example, a lamp or a display is dimmed or even disabled.
• It is possible that the control logic of the electronic control unit evaluates a forceps jaw force determined by a sensor or a jaw path (or a path of a component of the drive mechanism correlating therewith), which, taking into account a calibration factor, a storage for a subsequent further processing, a comparison with a Threshold, a comparison with a setpoint curve u. a can take place.
• It is possible that the control logic of the electronic control unit determines the number of continuous working strokes, which may be, for example, to a total of the pliers tool from production or a last maintenance continuous strokes or the continuous one day or within a predetermined period strokes. It is possible that the number of continuous working strokes is compared with a threshold, in which case the user can be signaled when the threshold value is exceeded that the pliers tool must be serviced immediately or after a certain number of further work strokes or even becomes unusable. It is also conceivable that when exceeding a specification for the maximum continuous working strokes deactivation of the pliers tool from the electronic Control unit is brought about what can be done, for example, by means of a locking of the moving parts of the pliers tool or the release of an integrated clutch in the drive mechanism. For further details on the determination and evaluation of a number of continuous working strokes is exemplified in the European patent application EP 2 995 424 A1 directed.
• It is also possible that the control logic of the electronic control unit carries out an evaluation of a machining process performed with the pliers tool. This evaluation can for example take place in that a detected force of the force (for example a maximum of the crimping force or the crimping force for reaching a predetermined partial stroke of the working stroke) is within a predetermined range of the force of the forceps or a course of the forceps within specified tolerances for an ideal course of the forceps Forceps lies.
• It is possible that the control logic of the electronic control unit carries out a storage of data, in particular the number of continuous working strokes, discrete values or courses of the forceps force and / or the path of the jaws u. The data stored in this way can then be read out later and used to document the work result generated with the pliers tool.
• The invention also encompasses embodiments in which data are stored, such as the number of working strokes that pass through, but readout of the data thus stored can only be performed by the manufacturer, with the manufacturer then based on this data, assessing a possible failure of the pliers tool can make.
• It is possible that by the control logic of the electronic control unit, an energy management is such that it is avoided that the electronic assembly consumes too much electrical energy when the pliers tool is not used at all and, for example, rests in a tool box or on a table. For this embodiment, the pliers tool basically assumes a standby mode, in which the electrical power consumption is minimized. In this case, a signal of an acceleration sensor is still evaluated in the standby mode such that a movement of the pliers tool is detected in particular by an occurring measured acceleration. When such movement of the pliers tool is detected by the user receiving the pliers tool, the control logic of the electronic control unit activates a standby mode so that the standby mode is exited. In the standby mode, an extended functionality of the electronic module can then be ensured, so that the electronic module is "woken up". For an embodiment of the invention, in the standby mode, for example, via a sensor detects whether an operation of the pliers tool takes place. The sensor can, for example, detect whether there is a passage through the working stroke, which can take place via a displacement sensor or a limit switch. Such monitoring whether an operation of the pliers tool takes place, for example, for a predetermined period (in particular 10 seconds) after switching to the standby mode. If no operation of the pincer tool is made within this period, it automatically returns to standby mode. It is also possible that a return to the standby mode is brought about by the control logic, if, after activation of the standby mode via the acceleration sensor, it is detected that the pliers tool is in a resting state for a predetermined period without any movement occurring.
• It is possible that in the event that (if necessary after switching from the standby mode to the standby mode as explained above) an operation of the pliers tool is detected by a sensor, by means of the control logic of the electronic control unit, a display and / or a lamp is activated. For example, the user can be signaled that the pliers tool is ready for operation. Furthermore, by means of the activation of the display, the display of the information relevant for the user can be initiated on the display.
• If it is detected by means of the control logic that no actuation of the pliers tool has taken place for a predefined first period of time or no movement of the pliers tool has taken place for a predefined second time span, a display and / or a luminaire can be deactivated. For this embodiment, preferably, the first time period is longer than the second time period.
• The control logic of the electronic control unit may be responsible for operating a wireless transmitting and / or receiving device. About the receiving device can be done, for example, a configuration of the pliers tool and / or the electronics assembly. On the other hand, via the wireless transmitting device, for example, a transfer of data concerning the work process carried out to an external evaluation device can take place.
• It is possible for the control logic of the electronic control unit to control at least one light (for example an LED). This control can be in the activation and deactivation of the lamp, the change in the color of the lamp, the change from a permanent to a flashing operation of the lamp u. Ä. exist.
• It is possible that the control logic of the electronic control unit dimmers a lamp or a display when it is detected that a state of charge of a battery or a rechargeable battery is below a threshold value, whereby the energy consumption of the pliers tool is reduced.
• It is possible that the control logic of the electronic control unit evaluates the default of a button that can be operated by a user by a light is activated when pressing the button for a first period of time, while pressing the button for a second period of time wireless connection is activated. Thus, for example, upon actuation of the button for the first time period, the light can be activated to activate the lighting of the environment of the pliers tool, ie a function similar to a flashlight, while for the operation of the button for the second period a connection setup (eg via Bluetooth).
• It is possible that the control logic allows a (re-configuration) of the pliers tool, which can be done by means of wireless or wired communication or even by direct input to an input field of the pliers tool. To name just a few non-limiting examples, the configuration may be that a name of the user or company in which the pliers tool is used, or a name or label of the manufacturer, is "loaded" on the pliers tool. It is also possible that the Configuration is that calibration factors are transmitted for used in the pliers tool sensors or the pliers tool is brought to know what kind of workpiece to be processed with the pliers tool, then under certain circumstances, different operations of the pliers tool can be controlled by the control logic.
• It is possible that the control logic detects whether a closed position of the hand lever has been reached. This can be done by evaluating the signal of a continuous path detecting sensor or a limit switch. This can be used on the one hand for counting the working strokes of the pliers tool and on the other hand for the evaluation of whether the working stroke of the pliers tool has been properly performed.
• It is possible that the control logic of the electronic control unit controls a locating function, via which a location of the pliers tool is possible. Alternatively or additionally, it is possible that the control logic controls an anti-theft device of the pliers tool. If, for example, the pliers tool has a GPS and a transmitting and / or receiving device, for example with a mobile card, a current position of the pliers tool can be transmitted to a smartphone when searching for the pliers tool, for example. However, it is also possible that the locating function merely consists in activating via an external device such as a smartphone that the pliers tool emits light or also emits an acoustic signal on the basis of which the finding of the pliers tool is simplified. It is also possible that for an anti-theft device, a signal for the activation of the anti-theft device is transmitted to the pliers tool, which then the pliers tool can be blocked by a controlled by an actuator lock or a clutch of the drive mechanism is transferred to an open state.
• It is also possible that the control logic of the electronic control unit ensures an electronic insertion control, via which a check is made as to whether an intended insertion of a workpiece into the forceps jaws has taken place. This can be done, for example, by a contact in the region of the receptacle of the pliers tool for the workpiece. Depending on the contact force or pressing the contact can then by means of The control logic to be closed on whether the workpiece has been correctly inserted into the recording or not.
• Furthermore, the control logic may be responsible for controlling a display, for example, a name or a label of a manufacturer, an owner or a user, a state of charge of a battery or a rechargeable battery, a measured forceps jaw force or a measured forceps jaw travel or a course of the same, a number of continuous working strokes or a number of remaining strokes, the result of an evaluation of a machining operation performed with the pliers tool, the result of a comparison of a determined number of continuous work strokes with a threshold and / or an indication of a required maintenance of the pliers tool indicates.

DESCRIPTION OF THE FIGURES

While Fig. 1 a pliers tool 1, here shows a crimping tool 2 in a closed position in fully assembled state show Fig. 2 and 3 the crimping tool 2 in different partially dismantled states. According to Fig. 3 is due to dismantling only a mechanical pliers part 3 remained (although, however, the mechanical pliers part 3 deviating from Fig. 3 also about the in Fig. 3 disassembled handles 4, 5 can have). The mechanical pliers part 3 represents a fully functional pliers tool 1 ', by means of which the desired processing of the workpiece can take place. The further components, in particular an electronic component 6, removed from the mechanical tong part 3 merely provide further functions which are not involved in the actual machining of the workpiece.

The mechanical pliers part 3 has a pliers head 7 and hand lever 8, 9 (which with the in Fig. 3 not shown handles 4, 5 may be formed). The pliers head 7 extends parallel to a pliers head plane 10. The pliers head plane 10 is at a very small acute angle with respect to the plane of the drawing according to the Fig. 1 to 3 inclined.

The hand lever 8, 9 and jaws 11, 12 move over the working stroke of the crimping tool 2 in the pliers head plane 10, which for the illustrated embodiment by Pivoting about a pivot axis, which is oriented vertically to the forceps head plane 10. The crimping tool 2 has a longitudinal axis 13, which corresponds to the main extension direction of the crimping tool 2 and the angle halves the hand lever 8, 9 corresponds or parallel to a fixed hand lever 8 and / or parallel to a fixed jaw 11 is oriented.

The pliers head 7 has a first pliers head part 14, in the region of which the pliers jaws 11, 12 are arranged, as well as a second pliers head part 15, which is arranged between the first pliers head part 14 and the hand levers 8, 9.

In the region of the pliers head part 15, the crimping tool 2 has a housing 16 which has not moved over the working stroke. For the illustrated embodiment, the crimping tool 2 is produced in a plate construction. In this case, the housing 16 is formed with cover plates 17, 18.

For the illustrated embodiment, the housing 16 and the cover plates 17, 18 fixedly connected to a fixed hand lever 8 and a fixed jaw 11, so that the jaw 11 performs no relative movement relative to the hand lever 8 over the working stroke of the crimping tool 2. In the region of the pliers head part 15, the coupling of the hand lever 8, 9 via a drive mechanism 19 with the jaws 11, 12, wherein this for the illustrated embodiment, only for the coupling of the movable hand lever 9 with the movable jaw is valid. Here, any drive mechanism 19 can be used, which preferably has a toggle lever drive with a pressure lever 20. The drive elements of the drive mechanism 19 can in this case be arranged between the cover plates 17, 18 and / or on the outside of these.

In Fig. 3 It can be seen that the pressure lever 20 of the drive mechanism 19 is located outside of a cover plate 17. About the power stroke is a relative movement of the pressure lever 20 against the fixed pliers part 21, which is formed with the hand lever 8, the housing 16, here the cover plates 17, 18 and the fixed jaw 11.

With regard to the further design of the drive mechanism 19, the drive elements used here, the coupling of the drive elements with each other and with the hand levers 8, 9 and the jaws 11, 12 and the design of the drive elements and the pivot bearing for the drive elements, the hand lever 8, 9 and Pliers jaws 11, 12 will not work on them pre-published European patent application EP 18 166 739.5 directed. In the context of the invention, however, any other pliers tool can be used in which, for example, the jaws are not pivoted relative to each other, but a translational movement of the jaws to each other and / or the hand lever are coupled via another drive mechanism with the jaws, see. also the embodiments of pliers tools according to the aforementioned prior art. Rather, it is decisive that the pliers tool has a pliers head part 15 which has a housing 16 and is arranged between the pliers jaws 11, 12 and the hand levers 8, 9.

The hand lever 8, 9 each have plate-shaped hand lever struts 22, 23, to which the handles 4, 5 can be pushed from the end of the pliers head 7 remote end and can be attached thereto, which can be done, for example, by a press connection and / or gluing. On the hand lever strut 22, which is part of the fixed pliers part 21, a holder 24 for a battery or an accumulator 25 is attached.

The electronics assembly 6 has a housing 26. The housing 26 has two half-shell-like housing parts 27, 28 and a further housing part 29, which forms a kind of cover 30, on.

Fig. 5 shows the assembly of the two housing parts 27, 28 with each other, while Fig. 6 the lid 30 shows. The housing parts 27, 28 are joined together in a joining direction 31, which is oriented vertically to a parting plane of the housing parts 27, 28 (which here corresponds to the pliers head plane 10). For this purpose, pins or projections of a housing part 27, 28 or pins formed separately from the housing parts 27, 28 (see the connecting pin 55) in the joining direction 31 into corresponding recesses of the housing parts 27, 28, which preferably takes place to form a press connection.

The two housing parts 27, 28 form a longitudinal recess oriented through recess 32 with a front opening 33, which faces the pliers head part 14, and a rear opening 34, which faces the hand levers 8, 9.

For complete assembly of the housing 26, the cover 30 in a joining direction 35, which is oriented parallel to the longitudinal axis 13, in conjunction with the assembled housing parts 27, 28th brought. The cover 30 has in the joining direction 35 protruding pin 36, which occur, in particular with a press fit, in recesses or holes 37 of the housing parts 27, 28th

The housing 26 is formed in the direction of the pliers head plane 10 in the area of the hand levers 8, 9 facing end face approximately V-shaped with legs 38, 39 of the V. In the region of the legs 38, 39 pass over the rear opening 34, the hand lever 8, 9 out of the housing 26 of the electronics assembly 6 out.

Inside the housing 16, the electrical and electronic components of the electronic assembly 6 are arranged, in an interior which is bounded outwardly by the housing parts 27, 28, 29 and inside by the housing 16 of the mechanical pliers part 3, here the Cover plates 17, 18, is limited.

The electronic assembly 6 has two boards 40, 41. The board 41 is supplied via a cable 42 from the battery or the accumulator 25 with electrical energy. The boards 40, 41 are connected to each other via a flexible cable 43. The cable 43 ensures on the one hand the power supply of the board 40 through the board 41 (and thus by the battery or the accumulator 25). On the other hand, via the cable 43, an exchange of data between the two boards 40, 41. The boards are screwed by screws 44 each having an associated housing part 27, 28. If the electronic assembly 6 is mounted on the mechanical pliers part 3, the boards 40, 41 extend outside of the housing 16, here the cover plates 17, 18, respectively on an outer side of the housing 16 and the cover plates 17, 18, preferably no electrical contact between the housing 16 and the boards 40, 41 takes place. In this assembled state, the cable 43 extends in a cross-section of the mechanical pliers part 3 U-shaped around an end face 45 of the mechanical pliers part 3 from a front side of the mechanical pliers part 3 to a back of the mechanical pliers part 3 (see Fig. 2 ).

In the area of the board 40, an input element 46 is arranged, which here is a button 47. In the area of the board 41, a display or a display 48 is arranged. The board 40 serves to process the input made by the user via the input element 46, while the board 41 serves to drive the display 48.

The housing part 48 has a tongue-like gate, under which the button 47 is arranged. If the user exerts pressure forces on the tongue-like gate 49 of the housing part 28 with the finger, an actuation of the button 47 can take place.

The housing part 27 has a window-like cutout 50. In and behind the cutout 50 is a cover plate 51 which protects the display 48 arranged behind it. As in particular in Fig. 8 can be seen, the board 40 has a here formed by a slot recess 52. A connection cable 53 is passed through the recess 52 of the display 48 to the other side of the board 40 where the connection cable 53 is connected to an electrical connection element 54 via which the board 40 controls the display 48.

In the exploded view according to Fig. 9 is that the lid 30 is U-shaped. The base leg of the U is located on the top of the mechanical pliers part 3 on the front side 45, which takes place in the region of the fixed pliers part 21. On the other hand, the side legs of the U extend along the housing 16, here along the cover plates 17, 18. The cover 30 is open on the side of the movable jaw 12 and the movable hand lever 9, so that under circumstances for large opening angle of the jaws 11, 12th the movable jaw 12 can come down from the lid 30. Under certain circumstances, the housing parts 27, 28 on the bottom of a corresponding slot, which allows a large opening angle of the movable jaw 12.

In Fig. 3 and 9 is also a connecting pin 55 can be seen, which enters the joining direction 31 in the recesses or holes 56 of the housing parts 27, 28th

By way of the boards 40, 41, there is an activation of luminaires 58, 59. For example, the luminaires 58 are a white LED, while the luminaire 59 is an RGB LED. For the illustrated embodiment, the boards 40, 41 each have a lamp 58a, 58b and a lamp 59a, 59b.

The housing parts 27, 28 are not transparent to light. On the other hand, the housing part 29 is completely or in a part assigned to the luminaires 58, 59 partially or completely transparent or translucent. The housing part 29 is preferably transparent in the region of a white light 58, so that by means of the light imitated by the light 58 a region outside the electronics module 6 can be illuminated. On the other hand, an RGB luminaire 59 can be arranged in a partially transparent or diffusely scattering light portion 74 of the housing part 29, so that this portion is backlit by the RGB lamp 59, so that outwardly in the region of the lid 30, a colored strip or a colored ring can be generated with suitable control of the RGB light 59.

At least one circuit board 40, 41 has an electronic control unit 57, wherein the two circuit boards 40, 41 together can form a control unit 57. The control unit 57 has control logic, which in particular parts or all of the listed below and in Fig. 10 can execute shown method steps:
In a method step 60, the electronics module 6 is connected by an external device such as a PC, a smartphone and the like. Ä., This connection can be wired or wireless. In the event that a wireless connection is to be established (for example via Bluetooth), in a method step 61 the button 47 is actuated for a longer period of time, in particular at least 5 seconds. If, on the basis of this prolonged actuation of the pushbutton 47, the control unit 57 detects that a connection is to be established, the RGB light 59 in a suitable color is controlled by the control unit 57 in a method step 62 so that it flashes. Thus, the user can see through the flashing backlighting of the lid 30 that the function of the connection setup is activated. In a method step 63, the connection routine of the control unit 57 is then started and the connection is established with the external device. If a device is found, a message such as "Coupling pliers tool no. Xx yes / no" appears on this device. A connection can then be made only after appropriate acknowledgment by the user. An established connection can be disconnected automatically, for example after 120 seconds, if the connection is not used within this period of time. Once the connection has been established, the activation of the luminaire 59 is changed in a method step 64 by deactivating it or producing a constant luminous effect, which also makes it clear to the user that a connection has been set up. After establishing the connection in this way, in a method step 65, programming of the electronic component 6 or data transmission to it can take place. For example, via the connection made, transmission of a name or identification of a manufacturer of the pliers tool 1, an owner of the pliers tool or the company in which it is used, or a name of the user or craftsman be transmitted. Furthermore, it is possible that in the method step 65 calibration factors for sensors used in the electronics module 6 are transmitted to the control unit 57. It is also possible that an individualization of the operation of the pliers tool 1 takes place, in which, for example, colors can be specified by the user, in which the lights 58, 59 are to emit light or threshold values can be specified for an evaluation of the measurement signals recorded by the sensors become.

If, on the other hand, no device for coupling is found within a predetermined period of time, in particular 60 seconds, during the attempt to establish the connection, the connection establishment is automatically terminated and the RGB light 59 is deactivated again. If, on the other hand, a coupling with a device is successfully completed, the RGB light 59 can be permanently illuminated for a predetermined period of time, in particular 5 seconds, and then deactivated again.

If the pliers tool 1 has been prepared for its use as explained above, the actual operation of the same can take place. First, the pliers tool 1 is in a process step 66 in an idle state, so that it is not moved. In method step 66, the pliers tool 1 is in a standby mode, in which the electrical power consumption of the electronic component 6 is minimized. However, the electronic module 6 monitors whether an acceleration sensor, which may also be integrated in the electronics module 6, detects an existing acceleration, which detects that the pliers tool 1 is taken by a user in the hand. For this purpose, the control unit 57 preferably compares the signal of the acceleration sensor with a threshold value. If a movement of the pliers tool 1 is detected, the electronic component 6 changes in a method step 67 from a standby mode to a standby mode in which an extended range of functions is ensured and a higher power consumption than in the standby mode. In the standby mode, it is checked in a method step 68 whether an actuation of the pliers tool 1 takes place. This can be done, for example, by checking whether the hand levers are contacted or a movement of a component of the pliers tool 1 takes place or acts on the hand levers, the drive mechanism or the jaws of a force. During this test and in the standby mode, the lights 58, 59 may still be deactivated and the display 48 may still be deactivated. Is done in standby mode within a predetermined period of time, For example, 60 seconds, no operation of the pliers tool 1, in a step 69, an automatic return to standby mode. If, however, an actuation of the pliers tool 1, the display 48 and at least one lamp 58, 59 are activated in a method step 70. It may then be generated on the display 48, the desired display, which indicates, for example, the number of continuous strokes, a state of charge of the battery or the accumulator 25 (preferably in percent or by means of a bar), a name or a label of a manufacturer, Owner or operator and any indication that a service of the pliers tool 1 is required because a number of continuous strokes is greater than a threshold value. After passing through the power stroke, the result of an evaluation of, for example, the force of the forceps force can also be carried out in a method step 71 on the display 48. In a method step 72, the electronics module 6 can automatically return to the standby mode if it is detected via the acceleration sensor that no movement of the pliers tool 1 has taken place more than, for example, 5 seconds.

If a turn on a preferably white light 58 to illuminate the environment of the electronics unit 6 done, this can be done by briefly pressing the button 47, while another short operation of the button 47 leads to deactivation of the light 58 or the light 58 automatically at a Timing or detection of the placement of the pliers tool 1 is disabled by the acceleration sensor. Thus, the button 47 is multifunctional, in which, depending on the type of actuation, here actuation time, via the button, the structure of the connection can be initiated or activation of the light 58 can take place.

In particular, the display has two or more lines of text which, for example, each have more than 10 characters. The character set may be an 8-bit ASCII character set, so that it can contain both alphanumeric characters and accents and umlauts.

If the control unit 57 recognizes that the state of charge of the battery or of the rechargeable battery 25 is insufficient, an automatic dimming of the lights 58, 59 and / or the display 48 by the control unit 57 or even a deactivation of the same can be effected.

As a sensor for detecting a movement of a component of the pliers tool 1, in particular the pressure lever 20, a so-called IR proximity sensor can be used which in this case can fulfill two functions. The sensor can detect whether there is a movement of components of the pliers tool 1, which can be closed on a passage of the power stroke and thus on an operation of the pliers tool 1. On the other hand, the sensor can be used to count the continuous strokes. When the clamp tool is opened and closed, a counter is incremented by the number 1. When switching from standby mode to standby mode, the IR proximity sensor activates.

For the described embodiment, no manual activation of the electronic assembly via a switch or button before the operation of the pliers tool 1 is required. For the illustrated embodiment, the pressure lever 20 has a nose 73 which is moved along the IR proximity sensor, so that the IR proximity sensor can detect the relative movement of the nose 73.

Between the cover plates 17, 18, an outwardly open space is formed in the region of the pliers head 7. This intermediate space is at least over a partial circumference of the pliers head 7 and in particular in the interior of the electronic component 6 and adjacent to this closed by a cover 75. The cover 75 has a T-shaped cross-section. The vertical leg of the T is inserted into the space between the cover plates 17, 18 and fixed there, which can be done by clipping or frictional connection with the cover plates 17, 18 or other attachment to this. The horizontal leg of the T covers the space between the cover plates 17, 18 to the outside, wherein the horizontal leg of the T at the end faces of the cover plates 17, 18 abuts. Preferably, the cover 75 is made of plastic. It is possible in this case that the vertical leg of the T is formed continuously, so that it forms a kind of rib, which allows the connection with the cover plates 17, 18. But it is also possible that the vertical leg of the T is formed only in partial peripheral areas of the pliers head 7, which then takes place only in these partial peripheral areas attachment of the cover 75 on the cover plates 17, 18.
