Electrical Contact With Fold-Over Flap for Seal Protection

The patent applies curvature by replacing the sharp edges of the box-shaped mating end with rounded or curved edges. This modification allows the contact to maintain its box-shaped structure for mechanical and electrical connection while the curved edges reduce stress concentration and prevent damage to the seal during insertion and extraction operations.

The patent applies preliminary action by providing a protective structure (such as a protective wall or shield) that is positioned in advance to prevent direct exposure of the contact beam to external factors during insertion. This protective structure absorbs or deflects impact forces before they can reach the contact beam, ensuring the beam remains protected while still allowing electrical connection functionality.

The patent applies dynamics by designing the contact beam with variable spring force characteristics rather than a constant high spring force. This may involve using a progressive spring mechanism or a beam geometry that provides different stiffness at different deflection levels, allowing for better control of the contact normal force while maintaining adequate mating force and reducing tolerance sensitivity.

The patent applies curvature modifications to the edges and corners of the rectangular box contact, making them rounded rather than sharp. This allows the contact to pass through the seal aperture more easily while distributing the stress more uniformly across the seal material, preventing concentrated stress points that would cause stretching and pinching of the seal glands.
