PRECI-DIP validates the performance of the spring-loaded contacts through a dynamic resistance curve. The dynamic resistance curve provides a way to assess the performance of spring-loaded contacts under dynamic conditions. The curve shows the variation in contact resistance and force as the spring-loaded contact is compressed from its uncompressed height to its fully compressed height. This information can be used to ensure that the spring-loaded contact has consistent and reliable electrical performance over its entire working range. The information from the dynamic resistance curve can also be used to identify any potential areas of instability, such as changes in contact resistance or force, which could affect the reliability of the electrical connection. On the graph, the blue curve is the contact resistance and red is the operating force. On the left, in the case of a hollow design, the contact resistance is highly variable due to the unstable nature of the contact point. On the graph, the blue resistance curve is scratchy and goes up to 200 mΩ. A resistance increase of a factor of ten or more is considered a discontinuity and can result in unreliable or unstable connections. In comparison, the blue resistance curve for the clip design is relatively straight, indicating that the contact resistance remains stable even when the piston is moving. This is a desirable characteristic for high-current applications, where a stable and low-resistance connection is essential. The straightness of the resistance curve is a result of the use of a multi-finger CLIP, which provides a compliant and reliable connection between the body and the piston. The CLIP ensures that the contact point remains stable even under conditions of shock and vibration, allowing for a more robust and reliable connection.
