A connector has a first housing () with two detection terminals () and a second housing () with a resilient deforming portion (). A detection unit () is in the second housing () and has two connecting portions () that rub against the detection terminals () in the process of connecting the two housings (). The connecting portions () are connected to the detection terminals () when the housings () are connected properly. Fixed contact portions () and movable contact portions () release a shorted state of the connecting portions () as the resilient deforming portion () is deformed and short the connecting portions () as the resilient deforming portion () is resiliently restored. A catch preventing structure () prevents foreign matter from being caught at the detection contact portions () when the housings () are separated.

Connector with detection unit

A flexing strip () is formed on a housing (). An interference part () is formed on a fit-on detector (). A distinguishing part () having a color different from the fit-on detector () is formed on the flexing strip (). The flexing strip () interferes with the interference part () and deforms while moving the fit-on detector () from a wait position to a detection position. The flexing strip () is released from an interference state with the interference part () and elastically restores to its original state when the fit-on detector () has reached the detection position. A position of the distinguishing part () relative to the interference part () changes before and after a flexing of the flexing strip () so that the distinguishing part () is exposed and can be seen from a distinguishing position.
