Claims (12)

  1. Werkzeug (1) zum Entkuppeln einer Verbindungsanordnung, wobei die Verbindungsanordnung aufweist:
    - einen ersten Verbinder, insbesondere einen mehrpoligen Verbinder (8), der Verhakungsreliefs aufweist, und
    - einen zweiten Verbinder, insbesondere einen mehrpoligen Verbinder (9), eines zum ersten Verbinder komplementären Typs, wobei der zweite Verbinder einen Sockel bildet, der dazu bestimmt ist, an einer Platte (P) befestigt zu werden, wobei der erste und der zweite Verbinder jeweils ein Gehäuse (80, 90) aufweisen, das sich entlang einer Achse (X) erstreckt und eine Anschlussseite aufweist, wobei der erste und der zweite Verbinder über ihre Anschlussseiten miteinander verbunden sind, wobei das Werkzeug (1) aufweist:
    - wenigstens einen Haken (5), der wenigstens ein Verhakungsrelief (52, 53) aufweist, das dazu bestimmt ist, durch Verhakung mit einem Verhakungsrelief (86, 87) des ersten Gehäuses zusammenzuwirken,
    - ein Hydrauliksystem (6), das wenigstens einen Zylinder (60), wenigstens einen Kolben, Hauptkolben (60p) genannt, der mit dem Zylinder einen Hauptzylinder bildet, und wenigstens eine Leitung (61, 62), die den Hauptkolben mit wenigstens einem Sekundärkolben verbindet, aufweist,
    wobei das Werkzeug (1) dadurch gekennzeichnet ist, dass
    - der Haken (5) außerdem eine Verriegelungsnase (51) aufweist,
    - das Hydrauliksystem betätigt werden kann, sobald die Verhakung wenigstens eines Reliefs des ersten Gehäuses durch das Verhakungsreliefs des Hakens erfolgt ist, wodurch die Verschiebung des Hauptkolbens hervorgerufen wird, welcher den Druck des Hydraulikfluids auf den wenigstens einen Sekundärkolben überträgt, welcher sich aus seiner inaktiven Position, in welcher er durch die Verriegelungsnase verriegelt ist, bis die Verhakung des Reliefs des ersten Gehäuses erfolgt, in eine aktive Position verschiebt, in welcher er entriegelt ist und somit eine Schubkraft auf die Platte ausüben kann, an welcher der Sockel befestigt ist, so dass das Entkuppeln/die Lösung der Verbindung zwischen dem Sockel und dem ersten Verbinder durchgeführt wird.
  2. Werkzeug (1) nach Anspruch 1, dadurch gekennzeichnet, dass das Hydrauliksystem wenigstens zwei Hauptkolben (60p) aufweist, deren Verschiebung synchronisiert erfolgt, wobei wenigstens zwei Leitungen (61, 62) die wenigstens zwei Hauptkolben mit wenigstens zwei Sekundärkolben verbinden.
  3. Werkzeug (1) nach Anspruch 1 oder 2, welches zwei Haken (5) aufweist, die jeweils wenigstens ein Verhakungsrelief (52, 53) aufweisen, das dazu bestimmt ist, sich an einem Abschnitt der Außenfläche (87, 86) des Gehäuses (80) des ersten Verbinders zu verhaken.
  4. Werkzeug (1) nach Anspruch 3, wobei einer der Haken als Verhakungsrelief ein Durchgangsloch (52) aufweist, während der andere der Haken eine Aussparung oder eine Rille (53) als Verhakungsrelief aufweist.
  5. Werkzeug nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass es einen Stützbügel (4) mit zwei voneinander beabstandeten Schenkeln (40, 41) aufweist, wobei das freie Ende jedes der beiden Schenkel einen Körper (42, 43) trägt, in welchem ein Element, das einen der Sekundärkolben (44, 45) bildet, längs verschiebbar zwischen seiner inaktiven Position, in welcher es wenigstens teilweise ins Innere des Körpers zurückgezogen ist, und seiner aktiven Position, in welcher es aus dem Körper weiter nach außen vorsteht als in seiner inaktiven Position, angebracht ist.
  6. Werkzeug nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass jeder Haken (5) schwenkbar zwischen einer Verriegelungsposition, in welcher die Verriegelungsnase den Sekundärkolben in seiner inaktiven Position verriegelt, und einer Verhakungsposition, in welcher sich das Verhakungsrelief mit dem Verhakungsrelief des ersten Gehäuses verhakt, während gleichzeitig die Nase von dem Sekundärkolben entriegelt ist, angebracht ist.
  7. Werkzeug (1) nach Anspruch 5 in Kombination mit Anspruch 6, dadurch gekennzeichnet, dass die Anbringung des Stützbügels um den ersten Verbinder herum das Schwenken jedes Hakens aus seiner Verriegelungsposition in seine Position der Verhakung mit dem Verhakungsrelief des Gehäuses des ersten Verbinders hervorruft und danach die manuelle Betätigung des Griffs die Verschiebung jedes Hauptkolbens hervorruft, welcher den Druck des Hydraulikfluids auf den Sekundärkolben überträgt, welcher sich aus seiner inaktiven Position in seine aktive Position verschiebt und dabei eine Schubkraft auf die Platte ausübt, an welcher der Sockel befestigt ist, so dass das Entkuppeln/die Lösung der Verbindung zwischen diesem Letzteren und dem ersten Verbinder durchgeführt wird.
  8. Werkzeug (1) nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass es einen Betätigungsgriff (2) für das Hydrauliksystem und einen Entkupplungskopf (3), der die Verhakungsreliefs trägt, aufweist.
  9. Werkzeug (1) nach Anspruch 8, wobei der Kopf von dem Griff verschieden und zu ihm versetzt ist.
  10. Werkzeug (1) nach einem der Ansprüche 8 oder 9, wobei der wenigstens eine Hauptzylinder des Hydrauliksystems in den Betätigungsgriff (2) integriert ist.
  11. Werkzeug (1) nach einem der vorhergehenden Ansprüche, wobei die Leitungen Hydraulikschläuche sind.
  12. Verwendung eines Werkzeugs (1) nach einem der vorhergehenden Ansprüche zum Durchführen des Entkuppelns/der Lösung der Verbindung zwischen mehrpoligen Verbindern einer Verbindungsanordnung, insbesondere an Bord eines Flugzeugs.
