Abstract
In an electrical device, a model series of electrical devices, and a production method, in particular for a converter, having a circuit board including circuit traces, the circuit board has two similar and/or identical contact area arrays, the contact area arrays in particular transitioning into each other through rotation and/or displacement. A first contact area array of the contact area arrays is fitted with a first power module, and the second contact area array is able to be fitted with a second power module, e.g., so that a respective electric motor is able to be supplied from the respective power module.
Claims16
An electrical device, comprising:
- a circuit board including circuit traces and including two similar and/or identical contact area arrays transitioning into each other through rotation and/or displacement, a first contact area array of the contact area arrays being fitted with a first power module, a second contact area array adapted to be fitted with a second power module, each power module adapted to supply power to a respective electric motor, the circuit board including a via connected in an electrically conductive manner by way of circuit traces on the circuit board to a contact area of the second contact area array;
- an additional circuit board having additional circuit traces and at least one connection device;
- and
- a second connector piece;
- wherein the second power module is mounted on the circuit board on the second contact area array, and being connected in an electrically conductive manner to the via by the circuit traces, the second connector piece being fitted on the additional circuit board and connected to the connection device in an electrically conductive manner by the additional circuit traces, the via being connected in an electrically conductive manner to the connection device by a cable.
A system, comprising:
- a first electrical device;
- and
- a second electrical device;
- each of the first electrical device and the second electrical device having a circuit board including circuit traces, and two similar and/or identical contact area arrays, the contact area arrays transitioning into each other through rotation and/or displacement, a first contact area array being fitted with a first power module, a second contact area array adapted to be fitted with a second power module;
- wherein the first electrical device includes a single connector piece adapted for supply of a single electric motor from the first power module, the first electrical device including a first housing part which includes a recess into which the connector piece is inserted, and the second power module not being mounted;
- wherein the second electrical device includes a second power module and two connector pieces adapted for supply of two independent electric motors from a respective power module, the second electrical device having a second housing part that differs from the first housing part and has two recesses into which a respective connector piece is inserted;
- wherein the second electrical device and the first electrical device differ in that in the second electrical device, the first housing part is replaced by the second housing part, and the second contact area array is fitted with the second power module.
A method for producing two variants of an electrical device having a circuit board that includes circuit traces and two similar and/or identical contact area arrays, the contact area arrays transitioning into each other through rotation and/or displacement, a first contact area array adapted to be fitted with a first power module, a second contact area array adapted to be fitted with a second power module, a first variant of the electrical device having a first housing part, which includes a single recess for a motor-connection piece, a second variant of the electrical device having a second housing part, which includes a first recess for a first motor-connection piece and a second recess for a second motor-connection piece, comprising:
- for production of the first variant of the electrical device, mounting the first power module, as a sole power module, on the first contact area array, and connecting the first power module in an electrically conductive manner to a first motor-connection piece, as a sole first motor-connection piece, which is inserted into the recess of the first housing part, and the second contact area array is not fitted with a component;
- and
- for producing of the second variant of the electrical device, additionally mounting a second power module on the second contact area array, which is connected in an electrically conductive manner to the second motor-connection piece, which is inserted into the second recess of the second housing part installed in the electrical device instead of the first housing part, the first motor-connection piece being inserted into the first recess of the second housing part.
