Devices for automated production of a plug from a plug housing and elongate contacts
The invention relates to a method for fabricating a plug ( 18 ) formed from a plug housing ( 19 ) and elongate contacts ( 3 ), the contacts ( 3 ) comprising a bent longitudinal axis ( 23 ) inside the finished plug ( 18 ), characterized by: introducing front portions ( 3 a ) of the contacts ( 3 ) into contact receptacles ( 17 ) of a plug housing part ( 7 ); holding the plug housing part ( 7 ) by means of a first holding arrangement ( 15 ) of a plug fabrication device ( 20 ); holding rear portions ( 3 b ) of the contacts ( 3 ) by means of a second holding arrangement ( 21 ) of the plug fabrication device ( 20 ); pivoting the first holding arrangement ( 15 ) with the plug housing part ( 7 ) held thereby relative to the second holding arrangement ( 21 ) with the contacts ( 3 ) held thereby, whereby the longitudinal axis ( 23 ) of the contacts ( 3 ) is bent in the region between their front portions ( 3 a ) and their rear portions ( 3 b ).
1. A device ( 20 ) for fabricating a plug ( 18 ) formed from a plug housing ( 19 ) and elongate contacts ( 3 ), the elongate contacts ( 3 ) inside the formed plug ( 18 ) having a bent longitudinal axis ( 23 ), said device comprising:
a first holding arrangement ( 15 ) for holding a plug housing part ( 7 ) having contact receptacles ( 17 ), into which front portions ( 3 a ) of the elongate contacts ( 3 ) are introduced;
a second holding arrangement ( 21 ) for holding rear portions ( 3 b ) of the elongate contacts ( 3 );
at least one die ( 8 ), which is movable into a region between the front portions ( 3 a ) and the rear portions ( 3 b ) of the elongate contacts ( 3 ); and
a folding tool ( 13 ) for engaging a wing ( 10 ) of the plug housing part ( 7 ), wherein
the first holding arrangement ( 15 ) and the second holding arrangement ( 21 ) are pivotable relative to one another, and the elongate contacts ( 3 ) are biased against the at least one die ( 8 ), such that the longitudinal axis ( 23 ) of the elongate contacts ( 3 ) bends in the region between the front portions ( 3 a ) and their rear portions ( 3 b ) of the elongate contacts ( 3 ), and
the folding tool ( 13 ) operates to engage the wing ( 10 ) of the plug housing part ( 7 ), after the pivoting of the first and second holding arrangements ( 15 , 21 ), to fold the wing ( 10 ) in order to form a closed plug housing ( 19 ).
2. The device according to claim 1 , wherein
the first holding arrangement ( 15 ) and the second holding arrangement ( 21 ) are movable relatively towards one another in order to introduce front portions ( 3 a ) of the elongate contacts ( 3 ) into the contact receptacles ( 17 ) of the plug housing part ( 7 ),
the first holding arrangement ( 15 ) comprises a gripper, which can adopt an open position and a gripping position, and/or
the second holding arrangement ( 21 ) comprises clamp parts ( 5 ) movable relative to one another.
3. The device according to claim 1 , further comprising a positioning tool ( 14 ) movable relative to the second holding arrangement ( 21 ) in order to position the elongate contacts ( 3 ) in the second holding arrangement ( 21 ), the positioning tool preferably comprising stops ( 4 ) for the front portions ( 3 a ) of the elongate contacts ( 3 ), and the stops ( 4 ) preferably being formed as stop sensors.
4. The device according to claim 3 , wherein the at least one of the stops ( 4 ) of the positioning tool ( 14 ) is set back relative others of the stops ( 4 ) of the positioning tool ( 14 ).
