Claims
- 1. 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:
- engaging a connector-holding block in a watertight manner with a second side of said connector housing at which said connector is fitted with a mating connector; and
- depressurizing an interior of said connector through said connector-holding block,
- wherein during said depressurization of the interior of said connector, said terminal, if inserted incomplete, is sucked in one piece with said waterproofing rubber stopper into a fully-inserted position.
- 2. 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:
- a waterproofness checking jig having a connector-holding block for engaging in a watertight manner with a second side of said connector at which said connector is fitted with a mating connector; and
- means for depressurizing an interior of said connector through said connector-holding block and means for holding the interior of said connector in the depressurized state,
- wherein during depressurization of the interior of said connector, said terminal, if inserted incompleted, is sucked in one piece with said waterproofing rubber stopper into a fully-inserted position.
- 3. An apparatus according to claim 2, wherein said connector-holding block is provided with a conductive pin for contact with said terminal to check said terminal for continuity, and wherein in the state where said connector-holding block engages in a watertight manner with said connector and where the depressurization of said connector has not yet been effected, said terminal is located forwardly of said conductive pin and remains not contacted with said conductive pin within limits of an engagement play between said terminal and a resilient locking lance provided in said connector housing for locking said terminal, and during the depressurization of the interior of said connector, said terminal is brought into contact with said conductive pin.
- 4. An apparatus according to claim 3, wherein a distance from said conductive pin to an engagement projection of said resilient locking lance is set larger than a distance from a front end of said terminal to an engagement hole in said terminal in which said engagement projection engages.
