Die Erfindung bezieht sich auf einen Locator für ein Crimp­gerät. Unter Crimpgerät versteht man hierbei ein Handgerät oder einen stationären Apparat zum Verpressen von elektrischen An­schlusselementen wie Kabelschuhen u. dgl. zwecks deren Befesti­gung an abisolierte Enden elektrischer Leiter.The invention relates to a locator for a crimping device. A crimping device is a handheld device or a stationary device for pressing electrical connection elements such as cable lugs and the like. Like. For the purpose of their attachment to stripped ends of electrical conductors.

Ein Crimpgerät weist zwei zu- und voneinander bewegbare Bak­kenträger auf, in denen je eine Arbeitsbacke angeordnet ist die ein oder mehrere Stanzelemente aufweist von denen jedes mit dem gegenüberliegenden Stanzelement in der anderen Backe ein zusam­menarbeitendes Paar beim Verpressen eines eingeführten An­schlusselementes bildet.A crimping device has two jaw carriers that can be moved towards and from each other, in each of which a working jaw is arranged, which has one or more punching elements, each of which forms a cooperating pair with the opposing punching element in the other jaw when pressing an inserted connecting element.

Unter Locator versteht man eine am Crimpgerät vorgesehene Zusatzanordnung die zum Zweck hat die richtige Lage des Anschlus­selementes im Stanzelementpaar zu gewährleisten. Eine vorbekannte Locatoranordnung, welche die Einstellung zweier verschiedener La­gen ermöglicht, ist z.B. in der EP-B-125 708 der Anmelderin be­schrieben. Die vorliegende Erfindung bezieht sich speziell auf einen für kleine Crimpkontakte (inkl. Steckerfahnen und Buchsen­teile) bestimmten Locator. Unter "kleiner Crimpkontakt" wird hierbei ein Anschlusselement der z.B. auf dem Schwachstrom- und/­oder Fernmeldegebiet üblichen Grössenordnung verstanden.A locator is understood to be an additional arrangement provided on the crimping device, which has the purpose of ensuring the correct position of the connection element in the stamping element pair. A known locator arrangement, which enables two different positions to be set, is e.g. in applicant's EP-B-125 708. The present invention relates specifically to a locator intended for small crimp contacts (including connector tabs and socket parts). Under "small crimp contact" a connection element is e.g. understood in the usual order of magnitude in the low-voltage and / or telecommunications area.

Die Erfindung stellt sich die Aufgabe einen Locator einfa­cher Konstruktion (für eine einzige Lage) zu schaffen, bei dem das betreffende Anschlusselement sowohl stabil, als auch - mit Hinsicht auch die im allgemeinen kleinen Abmessungen - äusserst genau in der gewünschten Verpresslage festgehalten wird. Diese Aufgabe wird mittels eines Locators gelöst welcher die im kenn­zeichnenden Teil des angeschlossenen Patentanspruchs 1 angeführ­ten Merkmale aufweist, wobei in Unteransprüchen vorteilhafte Wei­terentwicklungen angeführt sind.The object of the invention is to provide a locator of simple construction (for a single layer) in which the connection element in question is both stable and - with regard to the generally small dimensions - is held extremely precisely in the desired pressing position. This object is achieved by means of a locator which has the features stated in the characterizing part of the attached patent claim 1, advantageous further developments being set out in the subclaims.

Gemäss Fig. 1 weist eine näher nicht dargestellte Crimpzan­ge 10 zwei Backenträger 11, 12 auf, die gabelförmig gestaltet sind und im Zwischenraum zwischen ihren beiden Schenkeln jeweils eine (im dargestellten Beispiel zweiteilige) Backe 21, 22 tragen. Jede der Backen 21, 22 weist in an sich bekannter Weise drei Stanzelemente 21A, 21B, 21C bzw. 22A, 22B, 22C auf. Jeweils zwei gegenüberliegende Stanzelemente wie 21A/22A etc. bilden ein zu­sammenarbeitendes Paar, in dem ein Anschlusselement 30 an das ab­isolierte Ende 31A eines elektrischen Leiters 31 (Fig. 3) durch Verpressen mechanisch angeschlossen werden soll.1, crimping pliers 10 (not shown in more detail) have two jaw carriers 11, 12 which are fork-shaped and each carry a jaw 21, 22 (two-part in the example shown) between their two legs. Each of the jaws 21, 22 has three stamping elements 21A, 21B, 21C and 22A, 22B, 22C in a manner known per se. Two opposing punching elements such as 21A / 22A etc. form a cooperating pair in which a connection element 30 is to be mechanically connected to the stripped end 31A of an electrical conductor 31 (FIG. 3) by pressing.

Das Anschlusselement 30 besteht aus einem Befestigungsteil 30A der in an sich bekannter Weise zur mechanischen Verbindung mit einem elektrischen Leiter 31 - d.h. zum Verpressen mit diesem Leiter - dient, und aus einem (im dargestellten Beispiel hohl ausgebildeten) Kontaktteil 30B zum Herbeiführen einer elektri­schen Verbindung mit einem anderen Kontakt. Die Richtung, in der der elektrische Leiter 31 ins Anschlusselement 30 einführbar ist (Pfeil P3 in Fig. 2 und 3), wird in der vorliegenden Beschreibung und in den angeschlossenen Patentansprüchen als "axiale Richtung" bezeichnet.The connection element 30 consists of a fastening part 30A which, in a manner known per se, for mechanical connection to an electrical conductor 31 - i.e. for pressing with this conductor - and a contact part 30B (hollow in the example shown) for establishing an electrical connection with another contact. The direction in which the electrical conductor 31 can be inserted into the connection element 30 (arrow P3 in FIGS. 2 and 3) is referred to in the present description and in the attached patent claims as the “axial direction”.

An der einen Flanke des in der Zeichnung unteren Backenträ­gers 12 ist ein erfindungsgemässer Locator 40 geradling ver­schiebbar angeordnet im Sinne der Pfeile P1 (Fig. 1) bzw. P1′ (Fig. 3) in Richtung zu dem Backenträger 12 hin und umgekehrt. Der Locator 40 weist für jedes Stanzelementpaar wie 21A/22A ein in Richtung zu diesem Paar hin sich erstreckendes Griffelement auf, welches zum Festhalten des betreffenden Anschlusselementes 30 gestaltet ist. Im dargestellten Beispiel sind die Griffele­mente wie Finger 41A, 41B, 41C gestaltet, deren Querschnitt (sie­he Fig. 4) demjenigen des Hohlraums im Kontaktteil 30A des An­schlusselementes 30 entspricht, bzw. zumindest diesen Querschnitt nicht überschreitet oder überragt.On one flank of the lower jaw support 12 in the drawing, a locator 40 according to the invention is arranged such that it can be moved in a straight line in the direction of the arrows P1 (FIG. 1) or P1 '(FIG. 3) in the direction of the jaw support 12 and vice versa. The locator 40 has for each punching element pair such as 21A / 22A a grip element which extends in the direction of this pair and which is designed to hold the relevant connection element 30. In the example shown, the grip elements are designed like fingers 41A, 41B, 41C, the cross section of which (see FIG. 4) corresponds to that of the cavity in the contact part 30A of the connecting element 30, or at least does not exceed or exceed this cross section.

Die Finger 41A-C werden von einer Platte 41 getragen, bzw. sind als Bestandteile dieser Platte angefertigt. Die Platte 41 wird ihrerseits von einem Block 42 getragen in dem zwei durchge­hende Öffnungen vorgesehen sind, mittels welcher er an zwei im Backenträger 12 verankerten Führungstangen 13 (Fig. 2) gleitbar gelagert ist. Es ist offensichtlich, dass die beiden Führungs­stangen 13 auch durch eine einzige Führungsstange mit z.B. recht­eckigem Querschnitt ersetzt werden können.The fingers 41A-C are carried by a plate 41 or are made as part of this plate. The plate 41 is in turn supported by a block 42 in which two through openings are provided, by means of which it is slidably mounted on two guide rods 13 (FIG. 2) anchored in the jaw support 12. It is obvious that the two guide rods 13 can also be replaced by a single guide rod with e.g. rectangular cross section can be replaced.

Die Platte 41 und der Block 42 bilden somit ein Trägerorgan für die Griffelemente welches in axialer Richtung der Anschluss­elemente geradlinig verschiebbar ist. Die Führungsstangen 13 sind an ihren freien Enden mit Endanschlägen 13A (Fig. 2) versehen von welchen eine ausgerückte Ausganglage des Blockes 42, und damit des ganzen Locators 40, bestimmt ist.The plate 41 and the block 42 thus form a support member for the handle elements which can be moved in a straight line in the axial direction of the connection elements. The guide rods 13 are provided at their free ends with end stops 13A (FIG. 2), from which a disengaged starting position of the block 42, and thus of the entire locator 40, is determined.

An der hinteren (d.h. von dem freien Ende 12A des Backenträ­gers 12 mehr entfernten) Seite des Blocks 42 ist eine schräge, zum Backenträger 12 hin ansteigende Führungsbahn oder Rampe 42C vorgesehen, und an der Crimpzange 10 - vorzugsweise an dem nicht dargestellten Zapfen, der die beiden Backenträger 11, 12 mitein­ander verbindet, bzw. an einer Verlägerung 15 dieses Zapfens - ist ein Hebelorgan 14 schwenkbar angeordnet.On the rear (ie, more distant from the free end 12A of the jaw carrier 12) side of the block 42 there is an inclined guideway or ramp 42C which rises towards the jaw carrier 12, and on the crimping pliers 10 - preferably on the pin (not shown) which the connects two jaw carriers 11, 12 to one another, or on an extension 15 of this pin - a lever member 14 is pivotally arranged.

Das Hebelorgan 14 weist einen Hebelteil 14A und einen an die Führungsbahn 42C anliegenden Eingriffszapfen 14B auf. Eine nicht dargestellte Feder kann das Hebelorgan 14 dauernd in diejenige Schwenklage zwingen, in der Eingriffszapfen 14B (der vorzugsweise eine drehbare Hülse 14B′ trägt) an die Führungsbahn 42C ange­drückt wird.The lever member 14 has a lever part 14A and an engagement pin 14B which bears against the guideway 42C. A spring, not shown, can continuously force the lever member 14 into the pivot position in which the engagement pin 14B (which preferably carries a rotatable sleeve 14B ') is pressed onto the guide track 42C.

Auf zumindest einer der Führungsstangen 13 ist eine Druckfe­der 13B aufgezogen die den Block 42 dauernd in die in Fig. 1 dar­ gestellte ausgerückte Ruhelage zwingt. Hierbei sind die Griffele­mente 41A-C nur so lang, dass sie in dieser Ruhelage des Locators 40 vor dem Bereich der Backen 21, 22 und der Backenträger 11, 12 enden.On at least one of the guide rods 13, a compression spring 13B is mounted, which permanently shows the block 42 in FIG. 1 disengaged rest position forces. Here, the grip elements 41A-C are only so long that they end in this rest position of the locator 40 in front of the area of the jaws 21, 22 and the jaw supports 11, 12.

Die Arbeitsweise der Anordnung ist gemäss Fig. 2 bis 5 fol­gend. In der in Fig. 1 dargestellten geöffneten Lage der Backen­träger 11, 12 und der Backen 21, 22 wird der Hebelteil 14A des Hebelorgans 14 im Sinne des Pfeiles P2 betätigt, wodurch zufolge des Zusammenwirkens des Eingriffszapfens 14B mit der Führungsbahn 42C der Block 42 in die in Fig. 2 dargestellte eingezogene Be­reitschaftslage in maximaler Annäherung an den Backenträger 12 gebracht wird.The operation of the arrangement is as follows according to FIGS. 2 to 5. In the open position of the jaw carriers 11, 12 and the jaws 21, 22 shown in FIG. 1, the lever part 14A of the lever member 14 is actuated in the direction of the arrow P2, as a result of which, as a result of the interaction of the engagement pin 14B with the guideway 42C, the block 42 into the drawn in ready position shown in Fig. 2 is brought in maximum approximation to the jaw carrier 12.

In dieser Bereitschaftslage befinden sich die Griffelemente 41A-C im Raume zwischen den geöffneten Backen 11, 12, so dass sie leicht von der entgegengesetzten Seite des Gerätes, als wo sich der Locator 40 befindet, zugänglich sind. Demjenigen Griffelement 41C, welches dem gewählten Stanzelementpaar 21C/22C zugehört, wird ein Anschlusslement 30 zugeführt (im dargestellten Beispiel auf den Finger 41C aufgefädelt), um von dem Griffelement festge­halten zu werden. Dann wird der Hebelteil 14A freigelassen, und die Feder 13B führt den Block 42 in die Ausgangslage zurück (Fig. 3).In this standby position, the grip elements 41A-C are located in the space between the open jaws 11, 12, so that they are easily accessible from the opposite side of the device from where the locator 40 is located. A connecting element 30 is fed to that grip element 41C, which belongs to the selected punch element pair 21C / 22C (threaded onto the finger 41C in the example shown), in order to be held by the grip element. Then the lever part 14A is released and the spring 13B returns the block 42 to the starting position (FIG. 3).

Zum Unterschied von der Situation gemäss Fig. 1 befindet sich jetzt jedoch ein Anschlusselement 30 genau in der Lage be­züglich des Stanzelementes 22C in demjenigen Backenträger 12, an welchen der Locator 40 angeschlossen ist, in der es beim Schlies­sen der beiden Backen 21, 22 von diesem Stanzelement angegriffen bzw. beaufschlagt werden soll. In dieser, im folgenden als "ge­wünschte Lage" bezeichneten Lage befindet sich der Kontaktteil 30A völlig ausserhalb, und der Befestigungsteil 30 vollkommen innerhalb des Wirkungsbereiches des Stanzelementpaares 21C/22C und das Anschlusselement 30 ist hierbei auch gemäss Fig. 4 gegen­über dem Stanzelement 22C genau zentriert (gemeinsame Symmetrie­ebene E).In contrast to the situation according to FIG. 1, however, there is now a connection element 30 in the exact position with respect to the punching element 22C in the jaw carrier 12 to which the locator 40 is connected, in which it is when the two jaws 21, 22 are closed Punching element to be attacked or acted upon. The contact part is located in this position, hereinafter referred to as the "desired position" 30A completely outside, and the fastening part 30 completely within the effective range of the punching element pair 21C / 22C and the connecting element 30 is also exactly centered according to FIG. 4 with respect to the punching element 22C (common plane of symmetry E).

Höhenmässig sind hierbei die Griffelemente, im vorliegenden Beispiel also die Finger 41A-C, so gegenüber den betreffenden Stanzelementen 22A-C angeordnet, dass zwischen den ersteren und den letzteren ein Luftspalt L besteht, der unbedeutend grösser als die Materialdicke M des Anschlusselementes 30 ist, so dass das Anschlusselement 30 in der Situation gemäss Fig. 2 mühelos aufgefädelt werden kann, und bei der Rückführung des Locators in die Ausgangslage nich abgestreift wird.In terms of height, the grip elements, in this example the fingers 41A-C, are arranged opposite the punching elements 22A-C in question such that there is an air gap L between the former and the latter, which is insignificantly larger than the material thickness M of the connecting element 30. 2 so that the connecting element 30 can be easily threaded in the situation according to FIG. 2 and is not stripped when the locator is returned to the starting position.

In dieser Lage (oder bereits in der Lage gemäss Fig. 2) wird gemäss Fig. 3 der Leiter 31 mit seinem abisolierten Ende 31A im Sinne des Pfeiles P3 in den Befestigungsteil 30B eingeführt, wo­nach die Crimpzange in normaler Weise betätigt wird, so dass sie in der Lage gemäss Fig. 5 den Befestigungsteil 30B in an sich bekannter Weise verpresst. Danach wird das Backenpaar 21, 22 ge­öffnet und der Leiter 31 zusammen mit dem Anschlusselement 30 aus der Zange 10 und dem Locator 40 entfernt, wodurch eine Situation gemäss Fig. 1 wiederhergestellt wird.3, the conductor 31 is inserted with its stripped end 31A in the direction of arrow P3 into the fastening part 30B, after which the crimping tool is actuated in a normal manner, so that it is operated in accordance with FIG 5, the fastening part 30B is pressed in a manner known per se. The pair of jaws 21, 22 is then opened and the conductor 31 together with the connecting element 30 are removed from the pliers 10 and the locator 40, as a result of which a situation according to FIG. 1 is restored.

In Fig. 6 und 7 sind zwei Ausführungsformen 40′ bzw. 40˝ des erfindungs­gemässen Locators für Anschlusselemente 30′ , 30˝ dargestellt, deren Kontakt­teile 30B′ bzw. 30˝ nicht hohl sind, so dass sie keine Finger wie 41A etc. auf­nehmen können. Die Griffelemente sind deshalb wie Öffnungen 41A′, 41B′ bzw. 41A˝, 41B˝ gestaltet, in denen die Kontaktteile 30′, 30B˝ - vorzugsweise federnd - aufgenommen werden können. Anstatt der Platte 41 trägt der Block 42 zwei dickere Platten 410, 411 bzw. 410′, 411′ in denen jeweils eine der betreffenden Öffnung entsprechende Vertiefung eingearbeitet ist. Übersichtlichkeits halber sind die Platten 411, 411 abgebrochen dargestellt, so dass die Vertiefungen in der "C-Position" sichtbar sind.6 and 7, two embodiments 40 'and 40˝ of the inventive locator for connection elements 30', 30˝ are shown, the contact parts 30B 'and 30˝ are not hollow, so that they can not hold fingers such as 41A etc. . The handle elements are therefore designed like openings 41A ', 41B' and 41A˝, 41B˝, in which the contact parts 30 ', 30B˝ - preferably resilient - can be received. Instead of the plate 41, the block 42 carries two thicker plates 410, 411 and 410 ', 411' in each of which one of the opening in question appropriate deepening is incorporated. For the sake of clarity, the plates 411, 411 are shown broken off, so that the depressions are visible in the "C position".

Gleich der Platte 41 in Fig. 1-5 bilden die Plattenpaare 410, 411 und 410′, 411′ in den Fig. 6 und 7 ein Plattenorgan.Like the plate 41 in Fig. 1-5, the plate pairs 410, 411 and 410 ', 411' in Figs. 6 and 7 form a plate member.

Die Kontaktteile 30B˝ (fig. 7) sind selber mit federnden Elementen verse­hen, so dass diese nicht auch in den Öffnungen 41A˝ etc. vorgesehen werden müs­sen. Dies ist nicht der Fall dei den Kontaktteilen 30B′ (Fig. 6), und deshalb sind in den Öffnungen 41A′ etc. Federn 411A, 411B, 411C vorgesehen.The contact parts 30B˝ (fig. 7) are themselves provided with resilient elements so that they do not have to be provided in the openings 41A˝ etc. This is not the case dei the contact parts 30B '(Fig. 6), and therefore springs 411A, 411B, 411C are provided in the openings 41A', etc.

Die Platten 410, 411 bzw. 410′, 411′ sind mittels Schrauben 43 am Block 42 befestigt und können vorzugsweise austauschbar sein indem sie gleiche äusse­re Dimensionen aufweisen.The plates 410, 411 and 410 ', 411' are fastened to the block 42 by means of screws 43 and can preferably be exchangeable by having the same outer dimensions.

Es ist offensichtlich, dass im Rahmen der Erfindung auch andere Ausführungsformen als die beispielsweise dargestellte möglich sind. So kann z.B. der Trägerorgan der Griffelemente und/­oder dessen Antrieb anderwertig gestaltet sein. Die Platte 41 kann beispielsweise rechtwinklig nach unten abgebogen sein, die Führungsstangen 13 können durch im Anschluss an Öffnungen im abge­bogen Teil angeschweisste Hülsen passieren, und der Antrieb kann mittels eines exzentrischen Kammes od. dgl. geschehen.It is obvious that other embodiments than the example shown are also possible within the scope of the invention. For example, the support member of the handle elements and / or its drive can be designed differently. The plate 41 can, for example, be bent downwards at right angles, the guide rods 13 can pass through sleeves welded on following openings in the bent part, and the drive can take place by means of an eccentric comb or the like.
