Abstract

Abstract The invention provides a miniaturised and simplified connector for a flexible flat cable. A male connector 12 is formed from bus bars B and a male housing 13, the bus bars B being welded to a tip end of a flexible flat cable C, the male housing 13 being moulded so as to cover these bus bars B and a tip end portion of the flexible flat cable C. An opening portion 13b is formed in one face of the male housing 13. A female connector 17 is formed from terminal fittings 20 and a female housing 18, the terminal fittings 20 having resilient contacts 20b capable of resiliently making contact with the bus bars B when the connector 12 is fitted into the connector 17. A latching means 16 is provided between the female housing 18 and the male housing 13, and a waterproofing rubber ring 21 is located between an inner face of the female housing 18 and an outer face of the male housing 13.
