Plug-in connection system for plug-in connectors

Abstract

A plug-in connection system for a two-piece plug-in connection, comprising a plug-in connector and a matching mating connector, wherein the plug-in connector includes a latching unit with latching hooks provided thereon, which engage in groove areas on the mating connector. Here, a plurality of groove areas is circumferentially provided on the mating connector implemented in a sleeve-type way, which are offset relative to each other by a certain distance ds in relation to the plug-in edge of the mating connector. In the case of groove areas which are arranged in multiple pairs on the external side of the plug-in sleeve, only one latching hook pair engages at any one time during the plug-in operation into a latching groove in the groove area, whereas the other latching hooks respectively remain on a sawtooth flank before or after the one occupied latching groove. Thus, a very sensitive slide-on latching up to the mutual stop of any desired contacts becomes possible and a complex reception of the contacts is no longer necessary. Unlatching is carried out by lifting the latching hooks engaging in the latching grooves while withdrawing the external sleeve of the plug-in connector out of the latching grooves by means of opening hooks.
