Design example and Example for CD-device
Various Quick Connectors if accessible by free sound path between QC and CD.
Quick connectors (QC) are commonly used for many connections around the fuel system in cars. In particular there are a few such connections around the fuel tank.
In fuel tank assembly lines the fuel lines are connected to some nipples of the tank by such Quick Connectors. Doing this 8 h/day under time pressure the operator is unable to check whether each QC is assembled correctly. There-fore it happens in some cases that a QC is not really locked.
