Abstract:
A spark plug connector checking apparatus for checking a spark plug connector, said spark plug connector having a bushing stem having an axial direction and adapted to fit to said spark plug, said bushing stem including a terminal with a tip edge adapted to connect to a spark plug having a plug rim, a bushing with a connecting rim adapted to receive said plug rim, a connecting path connecting said bushing stem to a high-tension electrical cable, and a cap portion for fixing the connecting path, said apparatus comprising:a spark plug connector holding unit having:a cap holder unit including a movable cap holder in which the cap portion and bushing stem are fit and a magnetizable portion by which said cap holder unit may be magnetically fixed;a magnetic fixing mechanism that magnetically fixes and releases said magnetizable portion of said cap holder unit;a shift guide that provides free axial movement of said movable cap holder and thereby the cap portion and the bushing stem along the axial direction when the cap holder unit is magnetically fixed;an axial guide that prevents lateral movement of the bushing but provides free axial movement of the bushing along the axial direction;a bushing holder receiving the bushing, said bushing holder being spaced from said cap holder unit and including a threshold plate with a measuring threshold surface that receives the connecting rim of the bushing; anda thrust mechanism that moves said movable cap holder the bushing stem, and the bushing along the axial direction toward said bushing holder until the connecting rim of the bushing contacts said measuring threshold surface, thereby eliminating any gap between the connecting rim of the bushing and the measuring threshold surface.
