Title: Preventing incorrect connection of complementary electrical components
IPC: H01R13/645
Filed: 1980-09-22
Abstract: Two complementary, substantially identical electrical components, such as hermaphroditic connectors, are each modified by the provision of a rigid bar or other protuberance (40), which bars abut each other when an attempt is made at interconnection and hence prevent interconnection.
