AI Technical Summary

Problems solved by technology

However, the production costs of such coordinated plastic molded parts are very high
Furthermore, there is the risk that an excessive load acting on the connecting element and / or the insert part transversely to the longitudinal extension of the connecting element and the insert part could lead to fracture of at least one such plastic part and cause undesired leakage

Embodiment Construction

[0055] Figures 1 to 30 The detachable plug connection 1 and its main components are shown. Each plug connection 1 has a tubular plug-in part 2 which has at least one retaining projection 3 on the outer peripheral side. The insert part 2 can be inserted into the sleeve interior of the sleeve-shaped receiving part 4 . The receiving part 4 is connected to a connecting element 5 , which forms a detachable connection between the receiving part 4 and the insert part 2 after the insert part 2 has been pressed into the sleeve interior. After the insert part 2 has been pressed into the receiving part 4 , the retaining projection 3 provided on the insert part 2 engages from behind by the inwardly directed retaining edges 6 , 7 which can be bent or can be bent outwards. It is held deflected on the connection element 5 . The plug connection 1 has a sleeve-shaped locking element 8 which movably surrounds the connecting element 5 so that the locking element 8 can be Figure 5 Released ...

Abstract

The releasable plug connection (1) has a sleeve-shaped securing element (8) to which a connecting element (5) is slidably engaged. The connection element enables axial sliding movement of the securing element between release position with respect to opening movement of retaining edges (6,7), and backup position. The connector element is projected over the securing element during intermediate position of the securing element for retaining projection (3) that is bent upwards at an insertion unit (2) in the retaining edges.

Description

technical field [0001] The invention relates to a releasable plug connection with a tubular insert part, a sleeve-shaped receiving part and a connecting element connected to the receiving part, the insert part has at least one retaining projection on its outer circumference, the receiving part The inner space of the inner space is used to insert the tubular insertion part, at least one inwardly directed retaining edge is held on the connecting element in an outwardly curved or outwardly deflectable manner, the retaining edge engages behind the retaining protruding after pressing into the insert part department. Background technique [0002] EP 605801 B1 already discloses a detachable plug-in connection of the type mentioned at the outset, which is used as a hose connection for connecting two line sections of a liquid line. This known plug-in connection has a sleeve-shaped receiving part, into which a tubular insert part can be inserted, which has a holding projection in the...
