AI Technical Summary
The connectors of existing metal thin-film capacitive vacuum gauges are prone to oxidation when exposed to air for a long time, which leads to signal attenuation and noise interference, affecting measurement accuracy. Moreover, existing protective measures cannot effectively suppress oxidation, and maintenance operations are cumbersome.
The connector integrates a protection mechanism and a cleaning mechanism. Utilizing a stroke linkage transmission mechanism and an elastic reset component, it automatically achieves air inflation and vacuuming during insertion and removal. Combined with the cleaning mechanism, it automatically wipes the pins, achieving fully mechanical linkage protection and cleaning.
It effectively inhibits pin oxidation, stabilizes signal transmission and measurement accuracy, simplifies maintenance operations, reduces maintenance costs, and extends service life.
