Fluidic connector

Abstract

The invention relates to a fluidic connector intended to be connected to an elongated male element, configured to ensure a reliable, secure, and easily controllable connection. The male element comprises, from its so-called engagement end, optionally an initial cylindrical section having an initial diameter, an intermediate section continuously widening from this initial diameter to a larger intermediate diameter, and finally a final cylindrical section having a final diameter smaller than the third. This particular design creates, between the intermediate and final cylindrical sections, a first functional stop intended to cooperate mechanically with the connector and to enhance assembly security. The intermediate section, by its conical or flared geometry, plays a crucial role during insertion by causing controlled deformations of the locking mechanisms. Figure 2
