RELEASABLE PLUG CONNECTOR WITH FITTING INDICATOR

摘要

The proposal is for a releasable plug connector with fitting indicator for connecting fluid lines comprising a tubular insert section (2) with a peripheral securing rib (3), a cylindrical socket housing (1) with a socket (5) for a separate securing component (6) with elastically sprung engagement edges (7) directed radially inwards to engage behind the securing rib (3) after the insertion of the plug component (2) and an indicating component (4) which can be positioned in front of the socket aperture (15) of the housing (1). This consists of two spaced supporting rings (8 and 9) and at least two shoulders (10) joining the supporting rings (8 and 9) together, where one supporting ring (8) can be secured to the front wall (16) of the housing and the other supporting ring (9) away from the housing wall (16) can be supported on the insert section (2) on a flange (12) behind the securing rib (3). The shoulders (10) are formed to be elastically sprung on the opposite faces of the supporting rings (8 and 9) and joined together by outwardly curved bridge shoulders (11) so that, when the insert section (1) is pushed in, the shoulders (10) are pushed outwards and the considerably bowed bridge shoulders (11) project visibly beyond the housing wall (16).
