Adjustable Terminal-Spaced Noise Filter for Tunable Wire Harness EMI

The patent makes the capacitor's electrostatic capacitance adjustable by providing a variable capacitor or a switchable capacitor array, allowing the filter circuit to adapt to different noise frequencies dynamically. This resolves the contradiction by enabling both noise reduction reliability and frequency adaptability through a single adjustable component rather than fixed capacitors.

The patent changes the parameter of electrostatic capacitance from fixed to variable or switchable, allowing the same capacitor to serve multiple frequency ranges. By adjusting the capacitance value based on the noise frequency, the system achieves both reliable noise reduction and broad frequency coverage without requiring multiple fixed capacitors.

The patent designs a multi-functional terminal structure that serves both electrical connection and noise reduction functions. The terminal includes a capacitor element integrated into its structure, eliminating the need for separate noise reduction components. This integration reduces the total component count and manufacturing cost while maintaining effective noise reduction across multiple frequencies.

The patent merges the capacitor element with the terminal structure, combining the electrical connection function and the noise reduction function into a single integrated component. This consolidation reduces the number of discrete parts, simplifies assembly, and lowers overall cost while achieving reliable noise reduction.
