Abstract
To judge with certainty whether the condition of attachment of each metal terminal is proper, a method and apparatus are provided in which a thinned distal end portion of a lance check pin having guide portions contacts an inner surface of a lance flexing space. The lance check pin, when inserted into the lance flexing space, is kept in a proper posture by the guide portions. Therefore, misjudgment of the terminal position is avoided.
Claims29
A device for examining a connector having metal terminals inserted into cavities formed in a connector housing, and lances formed in the connector housing that are elastically deformed into lance flexing spaces upon insertion of the metal terminals, said lances being restored to engage said metal terminals when said metal terminals are brought into a properly-attached condition, to retain said metal terminals against withdrawal, said device comprising:
- at least one movable lance check pin with respect to the device, insertable into at least one of said lance flexing spaces, said at least one lance check pin, upon insertion, abutting against one of said lances when the metal terminals are in an improperly-attached condition, said at least one lance check pin having at least one guide portion for contacting inner surfaces of one of said lance flexing spaces so as to keep said at least one lance check pin in a proper orientation in one of said lance flexing spaces;
- and
- judgment means for judging from a position of the at least one lance check pin whether the at least one lance check pin is abutted against the lances.
A device for examining a connector having metal terminals inserted into cavities formed in a connector housing, and lances formed in the connector housing for each of the metal terminals that are elastically deformed into lance flexing spaces upon insertion of the metal terminals, the lances being restored to engage said metal terminals when said metal terminals are brought into a properly-attached condition, to retain said metal terminals against withdrawal, said device comprising:
- an inspection housing having a setting portion for receiving the connector to be examined;
- sliders mounted on said inspection housing for movement toward and away from the connector;
- a lance check pin provided on each of said sliders, said lance check pins being insertable into said lance flexing spaces to be abutted against ends of the lances when the metal terminals assume improperly-attached conditions, each of said lance check pins having at least one guide portion for entering an inner area of one of said lance flexing spaces so as to keep said lance check pins in a proper orientation in said one lance flexing spaces;
- and
- judgment means mounted on each of said sliders for judging from positions of the lance check pins whether said lance check pins are abutted against the ends of the lances.
A device for examining a connector wherein metal terminals are inserted into cavities formed in a connector housing of the connector, and lances formed in the connector housing are elastically deformed into lance flexing spaces upon insertion of the metal terminals, said lances being restored to engage said metal terminals when the metal terminals are brought into a properly-attached condition, to retain said metal terminals against withdrawal, said device comprising:
- a connector holder for holding the connector to be examined;
- an inspection housing provided in opposed relation to said connector holder;
- a drive mechanism for moving at least one of said connector holder and said inspection housing toward the other;
- sliders mounted on said inspection housing for movement toward and away from the connector;
- a lance check pin provided on each of said sliders, said lance check pins being insertable into said lance flexing spaces and, upon insertion, abutting against ends of the lances when the metal terminals are in improperly-attached conditions, each of said lance check pins having at least one guide portion adapted to enter an inner area of one of said lance flexing spaces to keep said lance check pin in a proper orientation in said one lance flexing space;
- and
- judgment means mounted on each of said sliders for judging from the positions of the lance check pins whether said lance check pins are abutted against the lances.
A device for inspecting a terminal inserted within a connector housing, said connector housing having a lance capable of securing the terminal in a locking position and a lance flexing space into which the lance flexibly extends as the terminal is inserted within the connector housing, said device comprising:
- a lance check pin that is movable between a first and second position and can be inserted in the lance flexing space when in the second position;
- and
- at least one guide portion for contacting an inner surface of said lance flexing space so as to keep the lance check pin in a proper orientation in said lance flexing space.
