Definitions

  • the invention relates to a plier-like device for pressing cable lugs which have a fastening part for fastening to the end of an electrical conductor and a training part for electrical connection to a contact element.

  • the normal frictional force between the mutually facing surfaces of the link 16 and the first jaw 13 or the device body 19 is expediently increased.
  • at least one of these facing surfaces can also be used with friction-increasing means such as corrugation, suitable covering, etc. provided, but this measure is not necessary in all cases.
  • the plate spring 24 can either be replaced by any other spring, or a resilient element can be omitted entirely, and the pressing force can only be exerted by the pivot pin 24.
  • the frictional force between the link 16 and the first jaw 13, regardless of how it is caused, has the effect that the link 16 has a tendency not to change its position relative to the first jaw 13, regardless of the position and the movements of the second jaw 14 It is therefore a position-retaining force.
  • the first end position of the link 16 shown in the drawing relative to the second jaw 14 (which in turn is in the open end position) is determined by the engagement of the driving pin 14b with the first end 15a of the groove 15 which is more distant from the first jaw 13.

  • pliers of this type tend to be provided with a locking mechanism which only allows the two jaws 13, 14 to be opened when the predetermined closed end position has been reached.
  • the link 16 is thus carried until the closed end position of the jaws 13, 14 is reached.
  • the length of the groove 15 is consequently dimensioned such that the driving pin 14b only in the closed end position of the jaws 13, 14, closer to the first jaw 13 occupies the second end 15b of the groove 15. It is obvious that this second end can either be located even closer to the first jaw 13 or that it can also be missing at all, ie the groove 15 can be open at the top. It is also easy to see that the groove 15 can also have any wider shape than that shown.
  • this groove end 15b acts as a further stop element which determines a second end position of the link 16; this second end position is functionally irrelevant, but the second stop element prevents with certainty that the link 16 cannot be pivoted out of its working area (ie contrary to the sense of the arrow P 1 ) even if the cable retaining force is overcome if no cable lug is inserted.
  • the link 16 initially remains in its last position, held by the frictional force the first jaw 13, and the finished crimped cable lug remains with its fastening part 101B in contact with the punching element 40a.
  • the other punching element 40b moves away from the cable lug 101 due to the opening movement of the second jaw 14.
  • the first end 15a of the groove acts again as a stop element and takes the gate 16 with, ie it pivots against the action of the frictional force of the arrow P 1 in the opposite sense.
  • the crimped cable lug 101 is inevitably lifted off from the stamping element 40a, even if it may have been clamped quite firmly, and the link 16, after the jaws 13, 14 have reached their open end position, returns to their first end position shown in the drawing the cable shoe can be easily pulled out of the receiving member 50, for.

Description

Die Erfindung bezieht sich auf ein zangenartiges Gerät zum Verpressen von Kabelschuhen die einen Befestigungsteil zur Befestigung an das Ende eines elektrischen Leiters und einen Anschulussteil zur elektrischen Verbindung mit einem Kontaktelement aufweisen.The invention relates to a plier-like device for pressing cable lugs which have a fastening part for fastening to the end of an electrical conductor and a training part for electrical connection to a contact element.

Die Verpressung von Kabelschuhen erfolgt zumeist in einem zangenartigen Werkzeug oder Gerät welches ein Paar zu- und voneinander bewegbarer Backen aufweist in denen ein oder mehrere Paare zusammenarbeitender Press-Stanzen angeordnet sind. Mehr als ein Stanzenpaar wird vorgesehen um Kabelschuhe mit verschiedenen Befestigungsteilen in einem und demselben Gerät bearbeiten zu können.The cable lugs are usually pressed in a plier-like tool or device which has a pair of jaws which can be moved towards and from one another and in which one or more pairs of press dies working together are arranged. More than one pair of punches is provided in order to be able to process cable lugs with different fastening parts in one and the same device.

Um eine sowohl in elektrischer als auch mechanischer Hinsicht einwandreie Verbindung zwischen dem Leiter und dem Kabelschuh zu erhalten ist es wesentlich, dass sich der Befestigungsteil beim Verpressen im Stanzenpaar genau in vorgesehener Lage befindet, und dass hierbei der Anschlussteil in keiner Weise von den Stanzen beeinflusst wird.In order to obtain a connection between the conductor and the cable lug that is impeccable both in electrical and mechanical terms, it is essential that the fastening part is exactly in the intended position during the pressing in the pair of punches, and that the connection part is in no way influenced by the punches .

Es ist bereits vorgeschlagen worden Kabelschuhzangen mit besonderen Anschlagorganen zu versehen, welche die Lage eines in die Zange zur Bearbeitung eingelegten Kabelschuhs kurz vor und während des Verpressens festlegen.It has already been proposed to provide cable lug pliers with special stop members which fix the position of a cable lug inserted into the pliers for processing shortly before and during the pressing.

Eine derartige Zange ist z. B. in EP-A-84 200 435 (0 124 919) angegeben, und weist ein Anschlagorgan auf welches wie ein zweiarmiger Hebel ausgebildet ist der im Bereich der Anlenkstelle einer schwenkbaren Zangenbacke an den Gerätekörper ebenfalls schwenkbar an den Gerätekörper angeschlossen ist, z. B. indem er am gleichen Schwenkzapfen wie die Zangenbacke gelagert ist. Der im Backenbereich sich erstreckende vordere Arm des Hebels weist eine ununterbrochene, gerade Haltekante auf, und der von der Anlenkstelle in entgegengesetzter Richtung sich erstreckende zweite Arm wird von einem Mitnehmerelement und von einem Endanschlagelement derart beeinflusst, dass das Anschlagorgan bei Betätigung der Zange Schwenkbewegungen durchführt, welche in gewissen Arbeitsphasen den vorderen Arm mit der Haltekante vor den Befestigungsteil eines in die Zange eingelegten Kabelschuhes bringen, und in anderen Arbeitsphasen den vorderen Arm aus diesem Bereich wieder wegführen. Irgendeine Halterung des Befestigungsteiles findet hierbei nicht statt.Such pliers are e.g. B. specified in EP-A-84 200 435 (0 124 919), and has a stop member on which is formed like a two-armed lever which is also pivotally connected to the device body in the region of the articulation point of a pivotable pliers jaw on the device body, for. B. by being mounted on the same pivot pin as the jaw. The front arm of the lever, which extends in the jaw region, has an uninterrupted, straight holding edge, and the second arm, which extends from the articulation point in the opposite direction, is influenced by a driver element and by an end stop element in such a way that the stop member carries out pivoting movements when the pliers are actuated, which in certain work phases bring the front arm with the holding edge in front of the fastening part of a cable lug inserted into the pliers, and in other work phases lead the front arm away from this area. No attachment of the fastening part takes place here.

In EP-A-84 200 434 (0 125 708) ist eine Kabelschuhzange beschrieben bei der an die Flanke der einen Zangenbacke ein Gehäuse fest angeschlossen ist weiches zumindest eine Aufnahmestrecke für den Anschlussteil eines Kabelschuhs aufweist deren Länge je nach der Länge des bearbeiteten Kabelschuhs eingestellt werden kann. Die Aufnahmestrecke hat die Form einer den Anschlussteil eng umschliessenden länglichen Kammer die nach obenhin zum grössten Teil frei ist. Der Anschlussteil wird, in der Kammer, welche zufolge der Befestigung des Gehäuses allen Bewegungen der betreffenden Zangenbacke folgt, festgehalten.EP-A-84 200 434 (0 125 708) describes a cable lug pliers in which a housing is firmly connected to the flank of the one pliers jaw and has at least one receiving path for the connecting part of a cable lug, the length of which is set depending on the length of the processed cable lug can be. The receiving section has the shape of an elongated chamber which closely encloses the connecting part and is largely free upwards. The connecting part is held in the chamber, which follows all movements of the relevant jaw of the pliers due to the fastening of the housing.

Die vorliegende Erfindung stellt sich die Aufgabe ein Gerät zu schaffen in dem die Lage des bearbeiteten Kabelschuhs genau fixiert ist, indem sein Anschlussteil in einem Aufnahmeglied eingesteckt ist, hierbei aber ferner erzielt wird, dass beim Öffnen der Backen verpresste Kabelschuh automatisch in eine maximal freie Lage bezüglich beider Backen gebracht wird. Dies ist besonders bedeutend wenn es sich um Kabelschuhe handelt, die am Anschlussteil eine nach auswärts vorspringende Festhaltefeder aufweisen (mit "nach auswärts" wird hier verstanden "auf die entgegengesetzte Seite hin als wo der unverpresste Anschlussteil herausragt ist"). Diese Aufgabe wird mittels eines Gerätes gelöst welches die Kennzeichen des Patentanspruchs 1 aufweist, wobei in angeschlossenen Unteransprüchen vorteilhafte Weiterentwicklungen aufgenommen sind. Nicht wie bisher sind also die Aufnahmeglieder starr an eine der Backen angeschlossen, sondern sie werden von einer Kulisse getragen welche zwischen den beiden Backen verschwenkbar ist, wobei diese Kulisse nicht wie bisher in bestimmten Arbeitsphasen gänzlich aus dem Bereich zwischen den beiden Backen herausgeschwenkt wird, sondern sie wird von den Anschlagelementen so gesteuert, dass sie, wenn auch in verschiedenen Lagen, dauernd in diesem Bereich verbleibt. Vorzugsweise hat die Kulisse die Form eines einarmigen Hebels der sich nicht über den Anlenkpunkt hinaus nach hinten erstreckt.The present invention has for its object to provide a device in which the position of the processed cable lug is precisely fixed by its connector is inserted in a receiving member, but it is also achieved that when the jaws are pressed, the cable lug is automatically pressed into a maximum free position with respect to both jaws. This is particularly important when it comes to cable lugs which have an outwardly projecting retaining spring on the connection part (with "outwards" is understood here "to the opposite side than where the unpressed connection part protrudes"). This object is achieved by means of a device which has the characterizing features of patent claim 1, advantageous further developments being incorporated in the connected subclaims. Not as before, the receiving members are rigidly connected to one of the jaws, but they are carried by a backdrop that can be pivoted between the two jaws, this backdrop not being pivoted completely out of the area between the two jaws in certain work phases, but rather it is controlled by the stop elements so that it remains in this area, even if in different positions. The link preferably has the shape of a one-armed lever which does not extend beyond the articulation point to the rear.

Gemäss Fig. 1 weist ein Kabelschuh 101 einen Anschlussteil 101A und einen Befestigungsteil 101 B auf, in den ein nicht dargestellter Leiter von rechts her in der Zeichnung eingeführt werden kann, um durch Verpressen festgehalten zu werden. Der Anschlussteil 101A weist einen nach auswärts herausragenden federnden Festhaltehaken 101A' auf. Derartige Kabelschuhe sind bekannt.1, a cable lug 101 has a connection part 101A and a fastening part 101B, into which a conductor (not shown) can be inserted from the right in the drawing in order to be held in place by pressing. The connecting part 101A has a resilient retaining hook 101A 'which projects outwards. Such cable lugs are knows.

Gemäss Fig. 2 und 3 weist eine Kabelschuhzange 10 an sich bekannter Konstruktion eine erste Backe 13 und eine zweite Backe 14 auf, die von einem Handgriff 12 betätigt werden kann. Die Backe 13 und ein Handgriff 11 sind zu einem länglichen Gerätekörper 19 starr miteinander verbunden. An der ersten Backe 13 bzw. am Gerätekörper 19 ist die zweite Backe 14 mittels eines Zapfens 24 schwenkbar angelenkt. Der Handgriff 12 ist einerseits mittels eines Zapfens 23 an die zweite Backe 14, und anderseits mittels eines Zapfens 32 an ein Ende einer Verbindungslasche 30 angelenkt. Die Verbindungslasche 30 ist an ihrem anderen Ende mittels eines Zapfens 31 an den Gerätekörper 19 schwenkbar angeschlossen. Der Zapfen 23 ist an einer hinteren, d.h. jenseits des Zapfens 24 belegenen Verlängerung 14E der Backe 14 belegen.2 and 3, a cable lug pliers 10 of known construction has a first jaw 13 and a second jaw 14 which can be actuated by a handle 12. The jaw 13 and a handle 11 are rigidly connected to one another to form an elongated device body 19. The second jaw 14 is pivotably articulated on the first jaw 13 or on the device body 19 by means of a pin 24. The handle 12 is articulated on the one hand by means of a pin 23 to the second jaw 14, and on the other hand by means of a pin 32 to one end of a connecting bracket 30. The connecting tab 30 is pivotally connected to the device body 19 at its other end by means of a pin 31. The pin 23 is on a rear, i.e. Beyond the pin 24 occupy the extension 14E of the jaw 14.

Von einer nicht dargestellten Feder wird das Backen- und Handgriffspaar normal in der dargestellten offenen Endlage gehalten die von einem ebenfalls nicht dargestellten Anschlag festgelegt ist. In der ersten Backe 13 sind drei Stanzelemente 40a, 41 a, 42a und in der zweiten Backe 14 drei mit ihnen zusammenarbeitende Stanzelemente 40b, 41 b, 42b angeordnet. Diese Konstruktion der Zange ist bekannt und liegt ausserhalb des Rahmens der vorliegenden Erfindung; eine Zange dieses Typs ist z. B. in DE-A-2 555 071 näher beschrieben.By a spring, not shown, the jaw and Handgr i ffspaar normally held in the illustrated open end position which is defined by a stop, also not shown. Three punching elements 40a, 41a, 42a are arranged in the first jaw 13 and three punching elements 40b, 41b, 42b which cooperate with them are arranged in the second jaw 14. This design of the pliers is well known and is outside the scope of the present invention; pliers of this type are e.g. B. in DE-A-2 555 071 described in more detail.

Erfindungsmäss ist an einer Flanke 13' der Backe 13 bzw. des Gerätekörpers 19 am Schwenkzapfen 24 eine schwenkbare Kulisse 16 in Form eines einarmigen Hebels angelenkt. Die Kulisse 16 erstreckt sich parallel mit der zweiten Backe 14 und zu deren vorderen Ende 14a hin, d.h. im wesentlichen bloss im Bereich vor dem den Anlenkpunkt bildenden Schwenkzapfen 24.According to the invention, a pivotable link 16 in the form of a one-armed lever is articulated on a flank 13 'of the jaw 13 or of the device body 19 on the pivot pin 24. The link 16 extends parallel to the second jaw 14 and towards its front end 14a, i.e. essentially only in the area in front of the pivot pin 24 forming the articulation point.

Aus der Flanke 14' der zweiten Backe 14 ragt im Bereich zwischen dem Schwenkzapfen 24 und dem Vorderende 14a ein Mitnehmerzapfen 14b hervor der ein erstes Anschlagelement bildet. In der der genannten Flanke zugewandten Innenfläche 16' der Kulisse 16 ist eine kreisbogenförmige Nut 15 angeordnet die ihren Krümmungsmittelpunkt im Schwenkzapfen 24 hat und in der sich der Mitnehmerzapfen 14b frei bewegen kann. Eine Tellerfeder 22 ist zwischen der Aussenseite der Kulisse 16 und dem Kopf des Schwenkzapfens 24 angeordnet und drückt die Kulisse 16 mit vorgewählter Kraft dauernd an die erste Backe 13 bzw. an den Gerätekörper 19 an, nicht aber an die zweite Backe 14, deren entsprechende Flanke 14', wie aus Fig. 3 ersichtlich, etwas eingezogen ist. Dadurch wird die normale Reibungskraft zwischen den einander zugewandten Flächen der Kulisse 16 und der ersten Backe 13 bzw. des Gerätekörpers 19 zweckmässiger Weise erhöht. Ausserdem kann zumindest eine dieser zugewandten Flächen auch mit reibungserhöhenden Mitteln wie Riefelung, geeigneter Belag u.s.w. versehen sein, aber diese Massnahme ist nicht in allen Fällen notwendig.A driver pin 14b protrudes from the flank 14 'of the second jaw 14 in the area between the pivot pin 24 and the front end 14a and forms a first stop element. In the inner surface 16 'of the link 16 facing the flank, an arcuate groove 15 is arranged which has its center of curvature in the pivot pin 24 and in which the driver pin 14b can move freely. A plate spring 22 is arranged between the outside of the link 16 and the head of the pivot pin 24 and presses the link 16 continuously with the preselected force against the first jaw 13 or against the device body 19, but not against the second jaw 14, whose corresponding flank 14 ', as can be seen in FIG. 3, is somewhat retracted. As a result, the normal frictional force between the mutually facing surfaces of the link 16 and the first jaw 13 or the device body 19 is expediently increased. In addition, at least one of these facing surfaces can also be used with friction-increasing means such as corrugation, suitable covering, etc. provided, but this measure is not necessary in all cases.

Die Tellerfeder 24 kann ferner entweder von irgendeiner anderen Feder ersetzt werden, oder ein federndes Element kann gänzlich entfallen, und die Anpresskraft nur vom Schwenkzapfen 24 ausgeübt werden.The plate spring 24 can either be replaced by any other spring, or a resilient element can be omitted entirely, and the pressing force can only be exerted by the pivot pin 24.

Die Reibungskraft zwischen der Kulisse 16 und der ersten Backe 13, ungeachtet wie hervorgerufen, hat die Wirkung, dass die Kulisse 16 eine Tendenz hat ihre Lage gegenüber der ersten Backe 13 nicht zu ändern, und zwar ungeachtet der Lage und der Bewegungen der zweiten Backe 14. Es handelt sich somit um eine lagebewahrende Kraft. Die in der Zeichnung dargestellte erste Endlage der Kulisse 16 gegenüber der zweiten Backe 14 (die sich ihrerseits in der geöffneten Endlage befindet) ist durch den Eingriff des Mitnehmerstiftes 14b mit dem ersten mehr von der ersten Backe 13 entfernten Ende 15a der Nute 15 bestimmt.The frictional force between the link 16 and the first jaw 13, regardless of how it is caused, has the effect that the link 16 has a tendency not to change its position relative to the first jaw 13, regardless of the position and the movements of the second jaw 14 It is therefore a position-retaining force. The first end position of the link 16 shown in the drawing relative to the second jaw 14 (which in turn is in the open end position) is determined by the engagement of the driving pin 14b with the first end 15a of the groove 15 which is more distant from the first jaw 13.

Unterhalb der oberen Endkante der Kulisse 16 ist im Anschluss an jedes Stanzelement 40b-42b der zweiten Backe 14 je eine Aufnahmekammer 50, 51, 52 für den Anschlussteil 101A eines Kableschuhs 101 bestimmter Grösser angeordnet. Die Aufnahmekammern haben im wesentlichen die Form einer den genannten Anschlussteil eng umschliessenden Kammer, die auch nach obenhin, d.h. in Richtung zur ersten Backe 13, zumindest teilweise geschlossen ist, bespielsweise von einem Randteil 16A der Kulisse 16.A receiving chamber 50, 51, 52 for the connecting part 101A of a cable shoe 101 of certain sizes is arranged below the upper end edge of the link 16 after each punching element 40b-42b of the second jaw 14. The receiving chambers essentially have the shape of a chamber closely surrounding the connection part mentioned, which also extends upwards, i.e. towards the first jaw 13, is at least partially closed, for example from an edge part 16A of the link 16.

Aus den Fig. 2 und 3 ist ersichtlich, dass in der geöffneten Endlage der Backen 13, 14, und wenn sich die Kulisse 16 hierbei in ihrer ersten Endlage befindet, alle Aufnahmekammern 50 - 52 von Seiten der Backen 13, 14 her frei zugänglich sind (wobei sie von der entgegengesetzten Seite zweckmässiger, aber nicht notwendiger Weise geschlossen sind, beispielsweise von einer Wandung 51 a, siehe Fig. 3).It can be seen from FIGS. 2 and 3 that in the open end position of the jaws 13, 14, and when the link 16 is in its first end position, all of the receiving chambers 50-52 are freely accessible from the side of the jaws 13, 14 (whereby they are closed from the opposite side in a practical but not necessary manner, for example by a wall 51 a, see FIG. 3).

In ein ausgewähltes Aufnahmeglied, z. B. 50, kann somit von der Backenseite her der Anschlussteil 101A eines Kabelschuhes 101 eingesteckt werden, wobei die Länge L der Aufnahmekammer so bemessen ist, dass der Befestigungsteil 101 B des Kabelschuhes 101 gegenüber dem Stanzenpaar 40a, 40b genau die Lage in Längsrichtung einnimmt, die zur genauen Verpressung erforderlich ist.In a selected receiving member, e.g. B. 50, the connection part 101A of a cable lug 101 can thus be inserted from the cheek side, the length L of the receiving chamber being dimensioned such that the fastening part 101B of the cable lug 101 assumes the position in the longitudinal direction with respect to the pair of punches 40a, 40b, which is required for precise pressing.

Wenn nun die zweite Backe 14 zufolge Beaufschlagens des Handgriffs 12 im Sinne des Pfeiles P2 ihre Schliessbewegung im Sinne des Pfeiles P1 beginnt, so hebt sich der Mitnehmerstift 14b vom ersten Nutenende 15a ab, wobei die Kulisse 16 vorerst von der Reibungskraft in unveränderter Lage gegenüber der ersten Backe 13 gehalten wird. Bald beaufschlagt jedoch das Stanzelement 40b von unten her den herausragenden Befestigungsteil 101 B des Kabelschuhs 101, wodurch dessen Anschlussteil 101A an das obere Abschlusselement 16A des Aufnahmegliedes 50 angedrückt wird. Demzufolge nimmt der Kabelschuh 101 wie ein Mitnehmerglied die Kulisse 16 bei Überwindung der Reibkraft mit, d.h. er verschwenkt sie auch im Sinne des Pfeiles Pi. Dies findet statt bis zu dem Augenblick, in dem der Befestigungsteil 101 B mit einem eingeführten Leiterende von den beiden Stanzelementen 40a, 40b vollkommen verpresst wird. Bekannter Weise pflegen derartige Zangen mit einem Sperrmechamismus versehen zu sein, der ein Öffnen der beiden Backen 13, 14 erst dann zulässt, wenn die vorbestimmte geschlossene Endlage erreicht worden ist. Die Mitnahme der Kulisse 16 erfolgt somit bis zum Erreichen der geschlossenen Endlage der Backen 13, 14. Die Länge der Nut 15 ist folglich so bemessen, dass der Mitnehmerstift 14b erst in der geschlossenen Endlage der Backen 13, 14, an das näher der ersten Backe 13 belegene zweite Ende 15b der Nut 15 stosst. Es ist offensichtlich, dass dieses zweite Ende entweder noch näher zur ersten Backe 13 hin belegen sein kann, oder dass es auch überhaupt fehlen kann, d.h. dass die Nut 15 nach oben hin offen sein kann. Es ist ferner leicht enzusehen, dass die Nut 15 auch jedwede breitere als die darstellte Form haben kann.When the second jaw 14 begins its closing movement in the direction of the arrow P 1 as a result of the action on the handle 12 in the direction of the arrow P 2 , the driver pin 14b lifts up from the first groove end 15a, the link 16 initially being unchanged from the frictional force is held against the first jaw 13. However, the punching element 40b soon acts on the protruding fastening part 101B of the cable lug 101 from below, as a result of which its connecting part 101A is pressed onto the upper end element 16A of the receiving member 50. Accordingly, the cable lug 101 takes the link 16 with it when the frictional force is overcome, ie it pivots it in the direction of the arrow Pi. This takes place until the moment in which the fastening part 101 B is inserted with a Conductor end is completely pressed by the two punching elements 40a, 40b. As is known, pliers of this type tend to be provided with a locking mechanism which only allows the two jaws 13, 14 to be opened when the predetermined closed end position has been reached. The link 16 is thus carried until the closed end position of the jaws 13, 14 is reached. The length of the groove 15 is consequently dimensioned such that the driving pin 14b only in the closed end position of the jaws 13, 14, closer to the first jaw 13 occupies the second end 15b of the groove 15. It is obvious that this second end can either be located even closer to the first jaw 13 or that it can also be missing at all, ie the groove 15 can be open at the top. It is also easy to see that the groove 15 can also have any wider shape than that shown.

Wenn der Mitnehmerstift 14b an das zweite Nutenende 15b anstösst, wirkt dieses Nutenende 15b als ein weiteres Anschlagelement welches eine zweite Endlage der Kulisse 16 bestimmt; diese zweite Endlage ist funktionsmässig belanglos, aber das zweite Anschlagelement verhindert mit Sicherheit, dass die Kulisse 16 auch bei Überwindung der lagebewahrenden Kraft nicht aus ihrem Arbeitsbereich (d.h. entgegen den Sinn des Pfeiles P1) verschwenkt werden kann wenn kein Kabelschuh eingelegt ist.When the driver pin 14b abuts the second groove end 15b, this groove end 15b acts as a further stop element which determines a second end position of the link 16; this second end position is functionally irrelevant, but the second stop element prevents with certainty that the link 16 cannot be pivoted out of its working area (ie contrary to the sense of the arrow P 1 ) even if the cable retaining force is overcome if no cable lug is inserted.

Wenn sich nun nach dem Verpressen des Kabelschuhs 101 die zweite Backe 14 wiederum von der ersten Backe 13 in einer Öffnungsbewegung entgegen dem Sinn des Pfeiles P1 zu entfernen beginnt, verharrt die Kulisse 16 vorerst, von der Reibkraft gehalten, in ihrer zuletzt eingenommen Lage gegenüber der ersten Backe 13, und der fertig verpresste Kabelschuh verbleibt mit seinem Befestigungsteil 101B am Stanzelement 40a anliegend. Das andere Stanzelement 40b entfernt sich jedoch zufolge der Öffnungsbewegung der zweiten Backe 14 vom Kabelschuh 101.If, after the crimping of the cable lug 101, the second jaw 14 in turn begins to move away from the first jaw 13 in an opening movement contrary to the direction of the arrow P 1 , the link 16 initially remains in its last position, held by the frictional force the first jaw 13, and the finished crimped cable lug remains with its fastening part 101B in contact with the punching element 40a. However, the other punching element 40b moves away from the cable lug 101 due to the opening movement of the second jaw 14.

Nachdem der Mitnehmerstift 14b im Zuge dieser Öffnungsbewegung wiederum das erste Ende 15a der Nute 15 erreicht hat, wirkt er von neuem als ein Anschlagelement und nimmt die Kulisse 16 mit, d.h. verschwenkt sie gegen die Wirkung der Reibkraft im entgegengesetzten Sinne des Pfeiles P1. Dadurch wird der verpresste Kabelschuh 101 vom Stanzelement 40a zwangläufig abgehoben, auch wenn er vielleicht ziemlich fest eingeklemmt war, und die Kulisse 16 nimmt, nachdem die Backen 13, 14 ihre offene Endlage erreicht haben, ihre in der Zeichnung dargestellte erste Endlage wieder ein, in der der Kableschuh leicht aus dem Aufnahmeglied 50 herausgezogen werden kann, z. B. durch Zug an den nun angeschlossenen Leiter, wonach das Gerät für die nächste Verpressung bereit ist.After the driving pin 14b in the course of the opening movement, in turn, the first end 15a of the groove has reached 15, it acts again as a stop element and takes the gate 16 with, ie it pivots against the action of the frictional force of the arrow P 1 in the opposite sense. As a result, the crimped cable lug 101 is inevitably lifted off from the stamping element 40a, even if it may have been clamped quite firmly, and the link 16, after the jaws 13, 14 have reached their open end position, returns to their first end position shown in the drawing the cable shoe can be easily pulled out of the receiving member 50, for. B. by train to the now connected conductor, after which the device is ready for the next pressing.

Die in Fig. 2 dargestellten Aufnahmekammern 50 - 52 haben eine Querschnittsform mit einer mittigen Einbuchtung wie 52A zur Aufnahme des Festhaltehakens 101A'. Auch diese Einbuchtung ist natürlich in der ersten Endlage freigelegt.The receiving chambers 50-52 shown in FIG. 2 have a cross-sectional shape with a central indentation such as 52A for receiving the retaining hook 101A '. This indentation is of course also exposed in the first end position.

In Fig. 4 ist als Alternativausführung eine Kabelschuhzange 10' gezeigt, die sich in dreielei Hinsicht von der Ausführung gemäss Fig. 1 unterscheidet. Fürs erste weist die Kulisse 116 ein mittels Schrauben 16C festgehaltenes austauschbares Gehäuse 16B auf in dem die Aufnahmekammern 50 etc. angeordnet sind. Es können somit je nach Bedarf Gehäuse bzw. Aufnahmekammern für verschiedene Kabelschuh-Anschlussteile angewandt werden.4 shows an alternative embodiment of a cable lug pliers 10 'which differs in three respects from the embodiment according to FIG. 1. For the time being, the link 116 has an interchangeable housing 16B which is held in place by means of screws 16C and in which the receiving chambers 50 etc. are arranged. Depending on requirements, housings or receiving chambers can therefore be used for various cable lug connection parts.

Fürs zweite ist am Schwenkzapfen 24 anstatt der Tellerfeder 22 eine Schenkelfeder 22A angeordnet die im Gerätekörper 19 und in der Kulisse 116 derart verankert ist, dass die Kulisse 116 dauernd in Richtung zur ersten Backe 13 hin beaufschlagt wird. In der Schliessphase der Backen 13, 14 entfällt dadurch, zum Unterschied von der beschriebenen Folge und dank der dauernden Wirkung der Feder 22A, die vorübergehende Mitnehmerfunktion des Kabelschuhs 101, was jedoch unwesentlich ist. Die Öffnungsphase verläuft genau gleich wie oben beschrieben.For the second, instead of the plate spring 22, a leg spring 22A is arranged on the pivot pin 24 and is anchored in the device body 19 and in the link 116 in such a way that the link 116 is constantly acted upon in the direction of the first jaw 13. In the closing phase of the jaws 13, 14, as a result of the difference in the described sequence and thanks to the permanent action of the spring 22A, the temporary driver function of the cable lug 101 is omitted, which is, however, immaterial. The opening phase is exactly the same as described above.

Zum dritten entfällt die Nut 15, und an ihrer Stelle ist an der Innenfläche der Kulisse 116 ein herausragender Zapfen 15a' angeordnet der sich in der ersten Endlage der Kulisse 116 weiter von der ersten Backe 13 als der Mitnehmerstift 14b' an der Flanke 14' der Backe 14 befindet, und gleich diesem Mitnehmerstift 14b' ein Anschlagelement bildet, welches das erste Nutenende 15a ersetzt (es ist bereits früher angeführt worden, dass das vom zweiten Nutenende 15b gebildete Anschlagelement im wesentlichen nicht benötigt wird). Es ist offensichtlich, dass das vom Zapfen 15a' gebildete Anschlagelement auch auf andere Weise gestaltet werden kann, z. B. als eine nach innen abgebogene untere Randkante der Kulisse 116.Thirdly, the groove 15 is omitted, and in its place an outstanding pin 15a 'is arranged on the inner surface of the link 116, which in the first end position of the link 116 extends further from the first jaw 13 than the driving pin 14b' on the flank 14 'of the Jaw 14 is located, and like this driving pin 14b 'forms a stop element which replaces the first groove end 15a (it has already been mentioned that the stop element formed by the second groove end 15b is essentially not required). It is obvious that the stop element formed by the pin 15a 'can also be designed in other ways, e.g. B. as an inwardly bent lower edge of the backdrop 116th

Im Rahmen des allgemeinen Erfindungsgedankens sind natürlich noch weitere Modifikationen denkbar. So kann z. B. der Mitnehmerzapfen an der Innenseite der Kulisse und die Nut in der Flanke der Backe angeordnet sein, oder es können andere Federtypen als eine Schenkelfeder in . der Alternativausführung angewandt werden. Die Aufnahmeglieder können auch für verschiedene Längen des Anschlussteiles gemäss der eingangs erwähnten EP-A-84 200 434 (0 125 708) gestaltet sein.Of course, further modifications are also conceivable within the framework of the general inventive concept. So z. B. the driver pin on the inside of the backdrop and the groove in the flank of the jaw may be arranged, or other types of spring than a leg spring in. the alternative version can be applied. The receiving members can also be designed for different lengths of the connecting part in accordance with the aforementioned EP-A-84 200 434 (0 125 708).

Die Erfindung kann auch bei Kabelschuh-Verpressgeräten angewandt werden wo die bewegliche Backe auf eine andere Weise als mittels eines Handgriffs angetrieben wird, z. B. hydraulisch.The invention can also be applied to cable lug pressing devices where the movable jaw is driven in a way other than by means of a handle, e.g. B. hydraulic.
