Tulip Plug-In Connector With Ceramic Cladding for Hot Electrolyzer Stacks

The patent applies parameter changes by utilizing the phase transition of the shape memory alloy from austenite to martensite. This phase change enables the material to automatically adjust its clamping force: in the austenite phase at operating temperature, the material maintains strong clamping force without relaxation, while in the martensite phase during assembly, it allows easy insertion. This resolves the contradiction by dynamically changing material properties rather than increasing structural complexity.

The patent directly applies phase transitions through the use of shape memory alloy that undergoes austenite-martensite transformation. The phase transition enables the connector to exhibit different mechanical properties at different temperatures: strong clamping force at operating temperature (austenite) and flexible insertion at assembly temperature (martensite). This eliminates the need for complex structural designs to maintain clamping force over time and temperature.

The patent applies segmentation by separating each plug-in connector into an independent module with its own housing. This allows individual connectors to be manufactured separately and then assembled onto the stacking plate, maintaining manufacturing simplicity while enabling independent replacement of failed connectors. The segmentation resolves the contradiction by eliminating the need for a common housing while preserving assembly efficiency through modular design.

The patent applies dynamics through the temperature-dependent phase transition of the shape memory alloy, which dynamically adjusts the clamping force based on operating conditions. This dynamic behavior ensures reliable electrical connection at high temperatures while allowing easy assembly at lower temperatures, resolving the contradiction between maintaining connection reliability and enabling easy maintenance.
