Abstract
Abstract An electrical unit includes a printed circuit board having a multi-pole plug and a main board having body edges and a plug to be connected to the multi-pole plug in a plug connection. A frame for receiving the printed circuit board has opposed sides and catch lugs being disposed on the opposed sides. The catch lugs have catch elements and the catch lugs are elastically deformed by the body edges upon connection of the plug of the main board to the multi-pole plug. A release lever is supported on the frame and has at least one pressure surface to be pivoted out of a connected position in which the catch elements are latched fixingly to the main board and into a release position in which the at least one pressure surface is braced against the main board for generating a force to undo the plug connection.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
167 words
An electrical unit, comprising: a printed circuit board having a multi-pole plug; a main board having body edges and having a plug to be connected to said multi-pole plug in a plug connection; a frame for receiving said printed circuit board, said frame having opposed sides, catch lugs being disposed on said opposed sides, said catch lugs having catch elements, said catch lugs being elastically deformed by said body edges upon connection of said plug of said main board to said multi-pole plug; a release lever being supported on said frame and having at least one pressure surface to be pivoted out of a connected position in which said catch elements are latched fixingly to said main board and into a release position in which said at least one pressure surface is braced against said main board for generating a force to undo said plug connection; and actuation surfaces associated with said catch lugs for receiving manual forces in said release position to unlatch said catch elements.
Claim 2
Dependent Claim
167 words
An electrical unit, comprising: a printed circuit board having a multi-pole plug; a main board having body edges and having a plug to be connected to said multi-pole plug in a plug connection; a frame for receiving said printed circuit board, said frame having opposed sides, catch lugs being disposed on said opposed sides, said catch lugs having catch elements, said catch lugs being elastically deformed by said body edges upon connection of said plug of said main board to said multi-pole plug; a release lever being supported on said frame and having at least one pressure surface to be pivoted out of a connected position in which said catch elements are latched fixingly to said main board and into a release position in which said at least one pressure surface is braced against said main board for generating a force to undo said plug connection; and actuation surfaces associated with said catch lugs for receiving manual forces in said release position to unlatch said catch elements.
Claim 3
Dependent Claim
37 words
The unit according to claim 1, including an extension of said release lever, and said actuation surfaces being associated with said catch lugs receive forces through said extension in said release position to unlatch said catch elements.
Claim 4
Dependent Claim
46 words
The unit according to claim 2, wherein said opposed sides of said frame are long sides, said catch lugs have unlocking levers extending outward from said long sides and away from said printed circuit board, and said catch lugs have outer surfaces being said actuating surfaces.
Claim 5
Dependent Claim
75 words
The unit according to claim 3, wherein said unlocking levers are substantially straight, at least three-sided prisms, each of said unlocking levers has a laterally outwardly-pointing side forming a respective one of said actuating surfaces, and each of said unlocking levers has a side surface facing toward said printed circuit board and being spaced from said printed circuit board by a distance being dimensioned in accordance with a desired maximum deflection of said catch lugs.
Claim 6
Dependent Claim
46 words
The unit according to claim 1, wherein said opposed sides of said frame are long sides, said catch lugs have unlocking levers extending outward from said long sides and away from said printed circuit board, and said catch lugs have outer surfaces being said actuating surfaces.
Claim 7
Dependent Claim
75 words
The unit according to claim 5, wherein said unlocking levers are substantially straight, at least three-sided prisms, each of said unlocking levers has a laterally outwardly-pointing side forming a respective one of said actuating surfaces, and each of said unlocking levers has a side surface facing toward said printed circuit board and being spaced from said printed circuit board by a distance being dimensioned in accordance with a desired maximum deflection of said catch lugs.
Claim 8
Dependent Claim
45 words
The unit according to claim 1, wherein said opposed sides of said frame are long sides, said catch lugs are each integral with a respective one of said long sides, and said long sides have reduced cross sections on both sides of said catch lugs.
Claim 9
Dependent Claim
20 words
The unit according to claim 1, wherein said catch lugs disposed on said opposed sides are offset from one another.
Claim 10
Dependent Claim
178 words
An electrical unit, comprising: a printed circuit board having a multi-pole plug; a main board having body edges and having a plug to be connected to said multi-pole plug in a plug connection; a frame for receiving said printed circuit board, said frame having opposed sides, catch lugs being disposed on said opposed sides, said catch lugs having catch elements, said catch lugs being elastically deformed by said body edges upon connection of said plug of said main board to said multi-pole plug; a release lever being supported on said frame and having at least one pressure surface to be pivoted out of a connected position in which said catch elements are latched fixingly to said main board and into a release position in which said at least one pressure surface is braced against said main board for generating a force to undo said plug connection; and said opposed sides of said frame are long sides, said release lever is supported on said long sides, and said release lever includes a bracket extending substantially between said long sides.
Claim 11
Dependent Claim
178 words
