  • the present invention relates to an arrangement with a male terminal and a female terminal, in particular for a hydraulic Kupplungssys- system, the arrangement allows a particularly simple installation and a space-saving design.
  • the present invention further relates to a hydraulic system, in particular a hydraulic coupling system, which has such an arrangement.
  • a disadvantage of the solutions of the prior art can be in particular an often comparatively large space requirement for the mechanical connection.
  • the female terminal has a Fixierschenkel for fixing the female terminal to the male terminal
  • the Fixierschenkel an outer side and an inner side comprises
  • the male terminal has an inner leg with an outer guide surface and an outer leg with an inner guide surface facing the outer guide surface, such that the fixing leg is positionable between the inner leg and the outer leg, wherein on the outer side of the Fixierschenkels and the inner Guide surface of the outer leg or on the inside of the Fixierschenkels and the outer guide surface of the inner leg is provided in each case a recess for partially receiving a snap ring, wherein in a state in which the male An is fixed to the female terminal, the snap ring is positioned in the recess of the inner side of the Fixierschenkels and the outer guide surface of the inner leg or in the recess of the outer side of the Fixierschenkels and the inner guide surface of the outer leg.
  • Such an arrangement allows an easy-to-install and space-saving connection of two components, in particular a hydraulic system, such as a hydraulic coupling system.
  • the described arrangement is in particular part of a hydraulic system, such as a hydraulic coupling system.
  • the order in particular serves to connect different components of the hydraulic system with each other.
  • the arrangement comprises a male connection and a female connection.
  • the male connection as well as the female connection can thereby be part of a basically selectable component or be connected to it or fixed to it.
  • the male connection can be fixed to the female connection.
  • the male connection can be fixed to a hydraulic line and the female connection can be connected to a cylinder or a clutch bell or the like.
  • the male connection and the female connection can be designed such that they have a passage for hydraulic fluid, which passages are connected when the male connection is connected to the female connection.
  • At least one of the male connection and the female connection is part of a connector.
  • a male terminal for example a male connector
  • a female terminal for example a female connector
  • Connectors can be effective. Only one, ie the male or the female connector, can be part of a connector or both the male and the female connector can be part of a connector.
  • the female terminal has a fixing leg for fixing the female terminal to the male terminal.
  • the fixing leg can in particular extend axially and parallel to a mounting direction, ie parallel to a direction in which the male terminal is pushed into the female terminal.
  • the fixing leg which may be configured approximately cylindrical, has an outer side, ie an ne outward side, and an inside, so an inward side, on.
  • the male connection has an inner leg with an outer guide surface and an outer leg with an inner guide surface directed towards the outer guide surface such that the fixing leg can be positioned between the inner leg and the outer leg.
  • the inner leg and the outer leg can be cylindrical and in particular coaxial and / or configured in the mounting direction. Therefore, in a state of the female terminal fixed to the male terminal, it is provided that the outer guide surface of the inner leg faces the inner side of the fixing leg and the inner guide surface of the outer leg faces the outer side of the fixing leg.
  • the fixation leg may slide along the inner leg and the outer leg and abut approximately and be guided by the guide surfaces and held in position.
  • the fixing leg and the inner leg and / or the outer leg have corresponding configurations, as described in detail below.
  • the recesses or the legs have a relative position relative to one another such that in a state in which the male connection is fixed to the female connection, that is to say in the fixing position of the male connection, the detonation ring in the recess the Fixierschenkels and the inner leg or outer leg is positioned.
  • This embodiment allows a secure and easy to be trained and thereby space-saving connection of male and female connection. Because the snap ring is present both in the recess of the fixing leg and in the inner or outer leg, axial movement of the male connection relative to the female connection can be prevented or at least limited depending on the configuration of the respective recess. As a result, sliding out of the male connection from the female connection can be reliably prevented, thereby ensuring a fixation of components, for example, of the hydraulic system.
  • An assembly can be particularly simple since a snap ring can often simply be widened or compressed radially in its diameter or radially and thus deform during assembly and then snap into the respective recesses. Thus, fixation may be facilitated by a simple telescoping male connector into the female connector when the snap ring is preassembled in the female connector or connector, such as in the corresponding recess.
  • the snap ring can easily be arranged in the interior of the arrangement, that is to say between the male connection and the female connection, so that no space for the snap ring or an assembly has to be provided on the outside of the arrangement. Therefore, the assembly as well as the arrangement as such can be designed to be particularly space-saving or space-saving. In particular, about 40% of today's space can be used, so more than half of the space can be saved. In addition, this leads to an increased stability, since external particular mechanical influences on the snap ring can be excluded.
  • a snap ring can be very stable in the axial direction despite an elasticity in the radial direction, so that, despite a simple assembly, a secure fixation male connection and female connection is possible.
  • a receptacle for receiving a sealing element is provided on the inside of the Fixierschenkels or the outer guide surface or, if a recess for partially receiving a snap ring is provided on the inside of the fixing leg and the outer guide surface of the inner leg, on the outside of the fixing leg or the inner guide surface of the outer leg a receptacle for receiving a sealing element is provided.
  • a sealing ring such as an O-ring, may be provided which seals the male terminal against the female terminal.
  • a recess for partially receiving a snap ring can be provided on the outer side of the fixing leg and the inner guide surface of the outer leg, and a receptacle for receiving a sealing element can be provided on the outer guide surface of the inner leg.
  • the sealing element can thus initially be positioned in the gap between the male connection and the female connection in the direction from the inside to the outside, and then the snap ring. In this configuration, it is thus possible to effectively prevent a hydraulic fluid from reaching the snap ring, in particular when using a hydraulic system. As a result, a resulting negative influence on the snap ring and thereby the fixation can be made possible.
  • an edge between a front side in the mounting direction and the recess for receiving the snap ring of the fixing leg facing guide surface of the inner leg or the outer leg is chamfered or bevelled.
  • the blasting ring which may in principle be pre-positioned in the fixing limb, slide along the inner limb or on the outer limb and, depending on the position of the recess for the snap ring on the inner limb or the outer limb, can widen or compress it become.
