| 摘要 |
The invention relates to a plug connection (1), comprising a first plug connector (2), a second plug connector (7) which can be inserted in the first plug connector (2), and a detent spring (13) fastened to the first plug connector (2) which engages in a groove (21) of the second plug connector (7) when a second plug connector (7) is inserted. The essential aspect of this is that the detent spring (13) can be moved from a locked position, in which position the detent spring (13) is prevented from effecting a movement radially outwards into an unlocked position, in which position the movement of the detent spring (13) radially outwards is released, and a release device (33) which can be selectively activated is provided on the first plug connector (2), and the activated release device (33) holds the detent spring (13) in the unlocked position. A method of using such a plug connection (1) is also defined. A plug connection (1) and a method of using this plug connection (1) are thereby provided, whereby it is possible to ensure in a most safe, simple and inexpensive manner that only properly manufactured plug connectors (2, 7) can be connected to one another. |

1. Plug connection (1) for connecting lines for pressurized liquids or gases, comprising a first plug connector (2) having an insertion end (3) and a fixing end (4) lying axially opposite, a second plug connector (7) having an insertion end (8) and a fixing end (9) lying axially opposite, and the second plug connector (7) can be inserted by its insertion end (8) in the first plug connector (2) via its insertion end (3), and a detent spring (13) fastened to the first plug connector (2) which, in a closed position on the first plug connector (2) and when a second plug connector (7) is inserted, engages in a radially extending groove (21) in an external face (10) of the second plug connector (7) by means of at least one retaining portion (19, 20) so that the second plug connector (7) inserted in the first plug connector (2) is prevented from becoming loose, and a radially extending bevel ramp (22) for the at least one retaining portion (19, 20) of the detent spring (13) is provided between the insertion end (8) and the groove (21) of the second plug connector (7), preferably directly in front of the groove (21), wherein the detent spring (13) in the closed position on the first plug connector (2) can be moved from a locked position, in which position the at least one retaining portion (19, 20) is blocked relative to the first plug connector (2) to prevent a movement radially outwards, into an unlocked position, in which position the movement of the at least one retaining portion (19, 20) radially outwards is released, and wherein a release device (33) which can be selectively activated is disposed on the first plug connector (2), and the deactivated release device (33) enables the detent spring (13) to be positioned in the locked position and the activated release device (33) holds the detent spring (13) in the unlocked position. |
