Abstract
Abstract An insertion and withdrawal device for a plug-in assembly, provided for insertion into a sub-rack. A plunger is disposed in a holding bracket of the device for the purpose of actuating a microswitch. A space, that permits a switching process of the microswitch prior to separation of the plug connector, is provided between a press-down shoulder of the pivoting lever and the front surface of a profiled rail.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
196 words
A plug-in assembly that is insertable into and withdrawable from a sub-rack having a profiled rail, the plug-in assembly comprising: a printed circuit board having a switching element attached thereto; a holding bracket connected to said printed circuit board and having a plunger guided thereon, said plunger being longitudinally displaceable toward and away from said switching element to engage and operate said switching element; and a pivoting lever hinged to said holding bracket and having a press-down shoulder that is engageable with the profiled rail, said pivoting lever being pivotable to a first position when said plug-in assembly is inserted into the sub-rack so that said pivoting lever engages with said plunger, and so that the press-down shoulder faces a front surface of the profiled rail, said pivoting lever further being pivotable to a second position when said plug-in assembly is removed; whereby pivoting of said pivoting lever from said first position to said second position first causes a displacement of said plunger and operation of said switching element, and subsequently causes the press-down shoulder to engage with the front surface of the profiled rail to effect the withdrawal of the plug-in assembly from the sub-rack.
Claim 2
Dependent Claim
196 words
A plug-in assembly that is insertable into and withdrawable from a sub-rack having a profiled rail, the plug-in assembly comprising: a printed circuit board having a switching element attached thereto; a holding bracket connected to said printed circuit board and having a plunger guided thereon, said plunger being longitudinally displaceable toward and away from said switching element to engage and operate said switching element; and a pivoting lever hinged to said holding bracket and having a press-down shoulder that is engageable with the profiled rail, said pivoting lever being pivotable to a first position when said plug-in assembly is inserted into the sub-rack so that said pivoting lever engages with said plunger, and so that the press-down shoulder faces a front surface of the profiled rail, said pivoting lever further being pivotable to a second position when said plug-in assembly is removed; whereby pivoting of said pivoting lever from said first position to said second position first causes a displacement of said plunger and operation of said switching element, and subsequently causes the press-down shoulder to engage with the front surface of the profiled rail to effect the withdrawal of the plug-in assembly from the sub-rack.
Claim 3
Dependent Claim
33 words
The plug-in assembly defined in claim 1, wherein a space is provided between the press-down shoulder and the front surface of the profiled rail when said pivoting lever is in the first position.
Claim 4
Dependent Claim
56 words
The plug-in assembly defined in claim 1, wherein said pivoting lever comprises two partial levers pivotable toward one another, one of said partial levers having a shoulder located opposite said plunger, and the other of said partial levers having the press-down shoulder formed thereon; further comprising a spring disposed between and interconnecting the two partial levers.
Claim 5
Dependent Claim
27 words
The plug-in assembly defined in claim 1, wherein said plunger is longitudinally displaceable in a direction essentially parallel to a longitudinal edge of said printed circuit board.
Claim 6
Dependent Claim
28 words
The plug-in assembly defined in claim 1, further comprising a pressure plate supported at an end of said plunger, said pressure plate being engageable with said switching element.
Claim 7
Dependent Claim
15 words
The plug-in assembly defined in claim 1, further comprising a spring acting upon said plunger.
Claim 8
Dependent Claim
44 words
The plug-in assembly defined in claim 6, further comprising a pressure plate supported at an end of said plunger, said pressure plate being engageable with said switching element; wherein said spring is a tension spring inserted between the pressure plate and said holding bracket.
Claim 9
Dependent Claim
52 words
The plug-in assembly defined in claim 1, further comprising a pressure plate supported at an end of said plunger, said pressure plate being engageable with said switching element; wherein said switching element comprises a microswitch positioned on said printed circuit board, said microswitch having an actuating pin located opposite said pressure plate.
Claim 10
Dependent Claim
25 words
The plug-in assembly defined in claim 1, wherein said holding bracket has a throughgoing bore formed therein, said plunger being guided in the throughgoing bore.
Claim 11
Dependent Claim
23 words
The plug-in assembly defined in claim 1, wherein said holding bracket has a groove formed thereon, said plunger being guided in the groove.
Claim 12
Dependent Claim
37 words
The plug-in assembly defined in claim 1, wherein said holding bracket has a detent formed thereon, and said pivoting lever has a catch that extends into the detent when said pivoting lever is in the first position.
Claim 13
Dependent Claim
33 words
The plug-in assembly defined in claim 1, further comprising a vertically extending front plate connected to said holding bracket and being located in a plane that is transverse to said printed circuit board.
Claim 14
Dependent Claim
28 words
The plug-in assembly defined in claim 12, wherein said holding bracket includes means for detachably securing said front plate and said printed circuit board to the profiled rail.
