Definitions
- the invention relates to a holding device for "Elkos" in order to mount them mechanically and electrically better and safer in a device can.
- the capacitors are described with, the protection of claim 1 but extends to the holder as such, even without capacitors.
- the devices are air-cooled frequency converters and servos. They are used in electric drive technology.
- Electrolytic capacitors in the air flow of the heat sink to install At the same time, the following functions have to be fulfilled
- EP-A 1 132 930 (Vacon Qy) describes one of these solutions. However, this is only for the protection and attachment of the
- Capacitors without meeting requirements for direct cooling of the condenser housing cup in the air flow and mechanical support of each of the capacitors near the center of gravity, since the capacitors are only enclosed in a closed jacket without additional support. They are installed and constrained in an intermediate housing, cf. there column 5, lines
- a heat dissipation must be done via an additional air and insulation material route. It may be necessary to fill the air gap between the condenser cup and the protective casing with a very expensive thermally conductive paste in order to be able to dissipate the temperature arising in the condenser at all. In addition occurs that naturally an outer diameter and a length even "equal" cup capacitors are subject to very high tolerances, whereby the air gap for the heat transfer can be very large.
- the problem is to make at least one assembled capacitor in the holding device form a prepositioned and stable-mounted unit, which is already adapted to the dimensional environment of the device in which it - the unit - is to be installed. To meet is also a mechanical attachment of the capacitor (s), so that even with vibration electrical connections and

- capacitors are constructed accordingly and receiving openings for the plurality
- Resulting holding device which defines the at least one capacitor axially and radially in the correct position, leaves a portion of each cup capacitor protrude freely, which length section during assembly in the device from the air flow can be washed around to cool the Elkos better (claim 1). It is the closed end of the respective cup capacitor, which is opposite to the connection end (axial).

- the stop in the depth preferably form bent tabs (claim 6).
- Another embodiment of the retaining clips can be integrally formed on the upper holder part spring tabs (claim 7).
- the retaining clips are pressed radially inward and stretch and fix the condenser cup on the circumference by means of the retaining clips preferably integrally formed toothings.
- the lower holder member When placing the lower holder member preferably come V-shaped beads of the retaining clips on the respective inner surface of the lower holder member for abutment and brace the retaining clips against the outer jacket of the Kondensatorenbechers. This due to a resulting dimensional overlap.
- the retaining clips support the capacitor cup advantageously and preferably in the region of the center of gravity. This has the advantage that the vibrations acting on the device or the capacitors during operation and the resulting axial or radial forces are absorbed and damped in order to destroy the contact surfaces between the electronic circuit board and connection sockets of the
- Each holder part, the upper (inner) as well as the lower (outer) holder part has for each of optionally a plurality of capacitors an opening which are aligned axially with its central axis on the central axis of the respective capacitor. In each case two openings are provided opposite or axially aligned.
- the claimed holding device differs in that a substantial part of the respective condenser cup protrudes freely without being completely encased and above the free-standing portion seals a respective sealing lip against the associated condenser cup.
- the cylindrical receptacles, the one on the upper holder part and the one on the lower holder part are therefore openings or - in other / mounted view - a through opening, which has a cylindrical frame or at least a cylindrical basic shape, which is adapted to the normal cylindrical shape of the cup of the capacitor is.
- Electrolytic capacitors have a correspondingly high capacity, which is preferably above 1000 ⁇ F (microfarads). They are adapted for the drive technology and the associated converters and are preferred there for the DC link.
- Holder part is pushed over the cup capacitor until it partially overlaps the upper holder part and is fixed to an edge region.
- This setting can be made either by clamping cam or by screws to be introduced.
- Holder part is widened to obtain the resulting elastic contact force to the capacitor cup for sealing purposes.
- Retaining clips support the respective cup capacitor from the inside in a mechanical way. Pressure in the radial direction, in particular in the region of
- Preferred serrations on the retaining clips ensure against axial displacement and also achieve a precise definition of the set position of the cup capacitors, even in the long term.
- the radial pressure is achieved by deflection of the formed as a spring tabs or spring clips retaining clips, including a geometric
- Forming preferably can serve a transverse to the longitudinal extent of the respective bracket lying bead.
- the radial pressure is applied from the inside of the lower / outer holder part when it is pushed axially and with its at least one opening slipped over the one or more cups.
- the mounted capacitors in the holding device form a pre-positioned and stable-mounted unit, which is already adapted to the dimensional environment of the device in which it - the unit - is to be installed.

- the capacitors 10 are polarity-proof by mechanical coding or electrical testing with the connection sockets 14 down.
- KondensatorbecheM 0 also defined on the mounting device, so that predetermined distances between the flat surface 15 of the capacitor terminals 14 and the contact surface 16 of the upper holder part 1 1 are possible.
- the degree of these distances is adjustable. It is arbitrary. This has the advantage that different heights of the position-determining power semiconductor
- Modules due to the axial displacement between capacitors and holder elements can be compensated with a part.
- the cylindrical openings 1 1a, 1 1 b take both capacitors 10, 10 '.
- the retaining clips 13 are in this assembly step with a small circumferential
