A waterproof connector is checked for waterproofness, which waterproof connector has a terminal-accommodating chamber into which a terminal is inserted and which is sealed with a waterproofing rubber stopper through which an insulated wire attached to the terminal passes. A connector-holding block of a waterproofness-checking jig engages in a watertight manner with the connector-fitting side of the waterproof connector, followed by depressurizing the waterproof connector with an ejector and comparing the pressure inside the waterproof connector with a reference pressure to determine the presence or non-presence of a leakage. Owing to the depressurization of the waterproof connector, the terminal, if inserted incomplete, is moved into a fully-inserted position in the connector housing in one piece with the waterproofing rubber stopper. A waterproof connector can be easily and reliably checked for waterproofness without making errors, while remedying incomplete insertion of a terminal.
A method of checking a waterproof connector for waterproofness comprising a connector housing with a terminal-accommodating chamber formed therein into which a terminal attached to an end of an insulated wire has been inserted from a first side of said connector housing, said terminal-accommodating chamber having been sealed by a waterproofing rubber stopper through which said insulated wire passes, said method comprising the steps of:
An apparatus for checking a waterproof connector for waterproofness comprising a connector housing with a terminal-accommodating chamber formed therein into which a terminal attached to an end of an insulated wire has been inserted from a first side of said connector housing, said terminal-accommodating chamber having been sealed by a waterproofing rubber stopper through which said insulated wire passes, said apparatus comprising:
