Title: Apparatus and method for inspecting dummy plug of waterproof connector
Inventor: FURUICHI KENJI
IPC: H01R43/00
Filed: 2003-01-06
Abstract: <P>PROBLEM TO BE SOLVED: To prevent a dummy plug from becoming easy to be removed resulting from the fact that inspection for non-insertion of dummy plug has been conducted.  <P>SOLUTION: A waterproof connector 2 is fitted into a recessed portion 13a of an apparatus main body 13 to make a depressurizing space 12 on the front side of the connector 2 airtight. Air in the depressurizing space 12 is then sucked by a depressurizing means 15. At that time, when there is non-insertion of a dummy plug, outer air is flowed through a vacant terminal holding hole, so that the pressure in the depressurizing space 12 does not decrease to negative pressure, indicating that there is non-insertion of the dummy plug. When there is no non-insertion of the dummy plug, airtight depressurizing space 12 is effectively depressurized to negative pressure, indicating that there is no non-insertion of the dummy plug. In that case, since the negative pressure exerts a force in a direction opposite to the direction that the dummy plug is removed, there is no possibility that the dummy plug becomes easy to be removed. Furthermore, a dummy plug which is originally in an incomplete insertion state is put into a full insertion state.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
