When a N-type female connector experiences poor contact, how should we handle it? We will briefly introduce three aspects: continuity testing, momentary disconnection testing, and single-hole separation force testing.
1. Continuity Testing: Currently, most N-type female connector manufacturers do not include this test in their product acceptance testing, but customers usually require continuity testing after one-click installation. Therefore, we recommend that manufacturers perform 100% individual continuity testing on some key models.
2. Momentary Disconnection Testing: Some N-type female connectors are used in dynamic vibration environments. Experiments can only prove whether the static contact resistance meets the standard, and cannot guarantee stability in dynamic environments. Since connectors with qualified contact resistance may still experience momentary power loss during vibration, shock, and other simulated environmental tests, it is best to perform 100% dynamic vibration testing on some N-type female connectors with high reliability requirements to assess their contact reliability.
3. Single-Hole Separation Force Testing: Single-hole separation force refers to the force required for the contact component to separate from a stationary state when in the mated state. Test results show that insufficient separation force in a single hole can cause momentary interruptions in data transmission signals under vibration and impact loads. Measuring the separation force of a single hole is more effective than measuring contact resistance in verifying contact reliability. Test results indicate that for sockets with deviations in single-hole separation force, precise measurement generally reveals that the contact resistance meets standards.
