Problems solved by technology
Due to the large mass of this capacitor type and the one-sided suspension on the circuit board via the connection socket, the contact surfaces and carrier material are subjected to strong loads, which can lead to contact problems or breakage of the printed conductors
Furthermore this prior art solution requires a separate protective enclosure for each capacitor length

Embodiment Construction
[0041] The implementation described here as an example meets the requirements listed in the introduction.
[0042] The cup capacitors as electrolytic capacitors 10 and 10' (abbreviated as "Elkos") and the holder H (consisting of components or sections 11, 12) together constitute a prefabricated assembly 33, which can be fitted into the shell of a device G In general, the device here is a frequency converter or servo regulator or any other application with similar requirements.
[0043] In a correspondingly configured assembling device, the correct polarity of the capacitor 10 is mechanically coded or electrically tested to insert the connecting socket 14 downward.
[0044] The upper cage portion 11 pre-assembled with the retaining clip 13 is also correctly coded and sleeved on the capacitor cup (synonymous with "cup capacitor") 10 by the assembly device, where the upper cage portion is represented as a double arrangement or Implemented to have any number of receptions for cup capa...

The invention relates to a holding device for encased capacitors (10, 10') which is used for electric drive engineering. The inventive holding device (H) comprises integrateable and separable lower and top holding parts (12, 11). Axially protruded retaining clamps (13) are arranged on the top holding part (11) around of each encased capacitor (10, 10'). The lower holding part (12) comprises an opening for the respective capacitor and each opening is surrounded with a sealing lip (29). When lower holding part (12) is mounted on the capacitors (10) and the top holding part (11), the retaining clamps (13) are pressed against the capacitors by the internal surface (22) of the lower holding part (12). The sections protruded from the respective opening of the lower holding part (12) are embodied in the form of the capacitor sections (32) freely extending directly to a cold air flow (W) of a device (G). The sealing lip (29) is sealingly placed on the external wall of each encased capacitor in such a way that the penetration of solid or liquid materials inside the lower holding part (12) is prevented, thereby making it possible to attain a high IP protection degree.
Description
Technical field [0001] The present invention relates to holding devices for "electrolytic capacitors" so that they can be installed in devices mechanically and electrically better and more safely. Capacitors are described together, but the protection of claim 1 also extends to capacitor-less holding devices. As devices, air-cooled frequency converters and servo mechanisms are specified, and they can be used in electric drive technology. Background technique [0002] In order to prolong the service life of the electrolytic capacitor, or to make the best use of the electrolytic capacitor, the temperature of the electrolytic capacitor core must be kept as low as possible. In an air-cooled device with a high protection class (IP54 and higher), it is suitable to place the electrolytic capacitor in the air flow of the cooler. To this end, the following functions should be met at the same time: [0003] The airtightness between the air cooling circuit (IP54 and higher) and the electroni...
