DETAILED DESCRIPTION

[0033] As schematically illustrated in the Figures, the cover part 9 has a pot-like configuration, so that a first printed circuit board 70 is accommodated therein and is pressed onto the cover part 9 by screws which are screwed into threaded holes of the cover part 9.

[0034] The cover part 9 is, for example, made of metal, e.g., die-cast aluminum.

[0035] A wall part 7, e.g., made of plastic, is also fastened on the cover part 9 and substantially covers the printed circuit board 70 so that the printed circuit board 70 is arranged in the spatial region bordered by the wall part 7 and the cover part 9.

[0036] The printed circuit board 70 is equipped with electronic components and a rotary switch 1, which is accessible and/or operable, e.g., rotatable, through a recess in the wall part 7. However, the cover part 9 is first to be detached from a lower part which is fastened on a motor housing or is formed integrally with it.

[0037] In addition, the printed circuit board 70 is equipped with a first and second potentiometer (2, 3), which are arranged on the printed circuit board 70 such that actuation of the respective potentiometer (2, 3) is provided when a closure screw 10 is removed, which is arranged in a recess of the cover part 9. A tool, for example a screwdriver, can be guided from the external surroundings through the recess in the cover part 9 to the potentiometer (2, 3) and the potentiometer (2, 3) is actuatable.

[0038] The memory unit 6 has a lower part 37 having pin regions 30 integrally formed, e.g., in one piece, on the lower part 37 and in particular spaced apart from one another, and an upper part 31.

[0039] Upper part 31 and lower part 37 are, for example, manufactured from plastic.

[0040] Through the recess in the wall part 7, DIP switches mounted on the printed circuit board 70 (4, 5) are also actuatable.

[0041] A further printed circuit board 36 is arranged in the memory unit 6 and is equipped at least with a long-term stable data memory and a DIP switch 35.

[0042] Parameters for starting up the converter are the storable in the memory unit 6 and a quick start-up is executable.

[0043] The memory unit 6 has a lower part 37 and an upper part 31 which are connected to one another, e.g., clip-connected.

[0044] Pin regions 30 are formed on the lower part 37 so that a guided connection of the memory unit 6 is provided. The guiding takes place during the production, e.g., when the memory unit 6 is plugged into the first printed circuit board 70 by plugging the pin regions 30 into corresponding recesses of the first printed circuit board 70.

[0045] The printed circuit board 36 has notches arranged opposite to one another on two sides, into which lug regions, which are formed on the lower part and are elastically deflectable toward the printed circuit board 36, snap in. The printed circuit board 36 is thus accommodated in the memory unit 6 in a form-fitting manner.

[0046] Elastically deflectable regions 33 are formed on two opposite sides on the lower part 37 and have a detent lug 32 and a corrugated region 34. The elastically deflectable regions 33 are movable towards one another with one hand and can be elastically pretensioned at the same time. The corrugated regions 34 prevent the fingers of this hand from slipping. During the elastic deflection of the regions 33, the memory unit 6 is guided for insertion into the cover part 9 in the direction of the longest extension of the pin regions 30 using the pin regions 30 through a recess in the wall part 7 and through at least two recesses in the first printed circuit board 70. In this manner, centering towards the first printed circuit board 70 is executable, so that conductor tracks formed as contacts on the further printed circuit board 36 of the memory unit 6 are insertable into a plug connector part, e.g., a socket part, mounted on the printed circuit board 70, e.g., without tilting. The plug connection of the further printed circuit board 36 to the first printed circuit board 70 is thus executable without tilting because of the guiding by the pin regions 30 arranged leading. First, when the memory unit 6 is inserted, the pin regions 30 penetrate the recesses in the first printed circuit board 70 and only then is the electrical plug connection effectuated.

[0047] The printed circuit board 36 is thus aligned perpendicularly to the first printed circuit board 70 and to the second printed circuit board 71 arranged in parallel to the first printed circuit board 70 and to the region of the wall part 7 surrounding the memory unit 6.

[0048] A simple connection is executable by the electrical plug connection between the first printed circuit board 70 and the further printed circuit board 36 of the memory unit 6. For this purpose, the form-fitting connection of the further printed circuit board 36 in and with the lower part 37 of the memory unit 6 and its form-fitting play-free connection, e.g., clip connection, by the elastically deflectable regions 33 to the wall part 7 secures the memory unit 6. The two pin regions formed on the lower part 37 center the memory unit 6 on the first printed circuit board 70.

[0049] A centering bolt 39 additionally formed on the lower part 37 is formed on the lower part 37 and protrudes into a correspondingly shaped further recess of the first printed circuit board 70. Thus, centering of the memory unit 6 is readily executable.

[0050] On the upper part 31 of the memory unit 6, further detent lugs 38 are formed, which are latched on the wall part 7, which has corresponding projection regions suitably shaped to form a latching connection with the detent lugs 38. The detent lugs 38 have insertion bevels, the bevel of which is opposite to the bevels formed on the detent lugs 32 of the elastic regions 33, however.

[0051] Thus, when the memory unit 6 is inserted, the elastic regions 33 are elastically compressed towards the lower part 37 and the detent lugs 32 pass through the recess arranged on the wall part 7. After relaxing the elastically deflectable regions 33, the detent lugs 32 abut the lower side, i.e., the side facing toward the first printed circuit board 70, of the wall part 7, so that the memory unit 6 is blocked from retraction. In addition, the detent lugs 38 abut the other side, thus, e.g., the upper side, of the wall part 7. The wall part 7 is thus delimited between the detent lugs 38 formed on the lower part 37 and the detent lugs formed on the upper part 31. In other words, the memory unit 6 is held in a form-fitting manner on the wall part 7.

[0052] The connecting line of the two detent lugs 38 is aligned perpendicularly to the connecting line of the two detent lugs 32 since the detent lugs 38 and 32 are arranged on different sides of the memory unit 6.

[0053] A DIP switch 35 is mounted on the printed circuit board 36 of the memory unit 6 and can be used to effectuate different parameterizations which determine the type of operation, e.g., the operating mode, of the signal electronics mounted on the printed circuit boards 70 and 71. The signal electronics thus function as a different AS-Interface slave type depending on the switch position of the DIP switches 35 and/or work with a different AS-Interface slave profile depending on the switch position of the DIP switches 35. Depending on the switch positions of the DIP switch 35, a respective different operating mode of the signal electronics accommodated in the cover part 9 is activated when the memory unit 6 is plugged in.

[0054] It is considered advantageous that no separate electrical devices, e.g., converters, have to be provided for the implementation of different AS-Interface slave profiles or types, and that the cover part 9 having the electrical device having signal electronics accommodated therein is usable for various profiles and types. For this purpose only the DIP switch 35 has to be provided and the switch position of the DIP switch 35 is used to set the respective desired AS-Interface slave profile or type.

[0055] A very quick and ready replacement is thus made possible in the event of a repair, in that the signal electronics together with the memory unit 6 are replaced and the DIP switch position is adopted.

[0056] The at least two notches 40 are arranged on the printed circuit board 36 on two opposite edges of the printed circuit board 36.

[0057] The cover part 9 is, for example, made of plastic. Alternatively, however, a configuration made of die-cast aluminum is also possible.

[0058] The wall part 7 is, for example, made of a highly insulating plastic and is therefore also capable of functioning as a thermal barrier.

[0059] For example, an electrical device is arranged as a converter motor, and the signal electronics are arranged in a cover part 9, into which a memory module arranged as a memory unit 9 is pluggable by a detent connection or clip connection, and a latching connection or clip connection is provided with the wall part 7 that is connected to the cover part 9 by screws or a detent connection, e.g., similar to the first printed circuit board 70.

[0060] In further exemplary embodiments, the cover part is placed on a lower part and tightly connected, and the lower part is arranged on a housing part of an electric motor and tightly connected. A compact configuration of the electrical device as a converter motor is thus implementable.
