Abstract
Abstract An electrical plug connector for electrically connecting and mechanically interlocking with a mating connector, including a connector housing having an outer support member. The outer support member is positioned substantially in the middle of the connector housing. The plug connector also includes a snap-on surface and a snap-fit device which is pre-molded to the connector housing. The snap-fit device includes a U-shaped bending bar which has a first limb and a second limb. The first limb is secured to the outer support member with a first connecting end and the second limb includes an unattached end and an orifice. The orifice is positioned substantially at the unattached end for engaging with a snap-on surface of the mating connector when the electrical plug connector is inserted into an opening of the mating connector. The plug connector is intended for use in electronic control instruments in motor vehicles.
