Study on Micro-Deformation Monitoring Technology of Contacts for Electric Connectors

Using optical fiber sensing technology to monitor the micro-deformation of the contacts for electric connectors. In this paper, the test scheme on the micro-deformation of the contacts of electric connectors is established; the micro-deformation test circuit is designed; and micro-deformation detecting test of the contacts for the electrical connectors is conducted under different temperature stresses conditions. Finally, the feature of the deformation affected by high temperature is analyzed.
