Patent Number: 6,250,972

Title: Connector having waterproof structure

Abstract: A waterproof connector is provided. The connector includes a housing 12 having terminal accommodating chambers 15 for accommodating terminals 14 and a cover 13 overlaid on the housing 12 to define wire insertion holes 20 between the cover 13 and the housing 12. The cover 13 is provided with a fall-stop engagement part 31 which engages with respective rear ends of the terminals 14 in order to prevent them from falling out of housing 12. In order to provide the connector with a waterproof structure, a resinous cover part 3 of each covered wire 1 is welded to both housing 12 and cover 13 by ultrasonic oscillating the housing 12 under pressure while each wire 1 is inserted into the wire insertion hole 20. Further, owing to the ultrasonic oscillation, the housing 12 is also welded to the cover 13 in the resultant waterproof structure.
