AI Technical Summary

Technical Problem

In the existing technology, the dynamic correlation analysis method of vibration signal and contact resistance cannot effectively monitor the mechanical and electrical performance degradation of the sheathless L-type pin connector, especially the stress concentration at the pin root during repeated insertion and removal, which leads to deformation accumulation and contact surface offset.

Method used

Strain gauges are used to simultaneously acquire micro-strain signals and contact resistance signals at the root of the insertion pin. Combined with insertion and removal events, analysis time periods are divided, deformation characteristic values ​​and hysteresis characteristic values ​​are calculated, performance degradation coefficients are generated, and early warning is triggered through trend separation processing.

Benefits of technology

It enables early performance degradation monitoring of unsheathed L-type pin connectors, improving monitoring accuracy and reducing maintenance costs. It can provide early warning when the pins show invisible bending deformation, thus avoiding equipment failure.

Abstract

The invention relates to the technical field of electronic connector performance monitoring, in particular to a connector performance detection method, and aims to solve the problem that a method for realizing performance early warning through dynamic correlation analysis of vibration signals and contact resistance in the prior art is not suitable for an L-shaped pin connector without a sheath. According to the method, micro-strain signals and contact resistance signals are synchronously collected, analysis time periods are divided in combination with plugging events, the plastic deformation accumulation degree and signal response delay characteristics are quantitatively evaluated, performance degradation coefficients are generated through fusion, and trend analysis is carried out; the problem that the relevance between the mechanical deformation and the electrical performance cannot be quantitatively evaluated in the prior art is effectively solved, and the method has the advantages of realizing early warning, improving the monitoring accuracy and reducing the maintenance cost.
