Solution Approach 1:

The rigid copper bar is segmented into multiple flexible cables, allowing the electrical connection system to accommodate capacitor deformation while maintaining current passage capability. Each cable can independently flex as the capacitor expands, preventing mechanical constraint.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Flexible cables replace rigid copper bars to provide electrical connection. These cables have the flexibility to accommodate capacitor deformation while maintaining electrical connectivity, resolving the contradiction between rigid structural support and deformation capability.

Inventive Principle:

Solution Approach 1:

Multiple flexible cables are combined to replace a single rigid copper bar. This merging of multiple flexible conductors achieves both deformation accommodation and high current passage capability, as the collective cross-sectional area of multiple cables can match or exceed that of a single rigid bar.

Inventive Principle:

AI summary

The device has a frame (12) having two rigid edges (16), and lids (13) cooperating with ends of each of capacitors, where one of the capacitors is a deformable capacitor. Deformable connection strips (14) connect the frame to the lids, where one of the lids and the strip are conformed in a perforated plate. The rigid edges are obtained by folding lateral edges of the plate, where the plate is made of galvanized steel and comprises four openings (31) for the lid. An independent claim is also included for a support of a power capacitor equipped of electrical contact terminals, comprising a holding device.
