Specifications for RJ45 connector network interfaces

RJ45 connector network interface is divided into many specifications, today's RJ45 connector manufacturers ship more types are: RJ45 connector 90-degree plug-in with LED lights / no lights, RJ45 connector 180-degree direct plug with lights / no lights, RJ45 countersunk plate plug-in, RJ45 double side-by-side, RJ45 dual layer / with USB interface and so on.
1.Contact resistance: match with male and female seat, then measure and record the contact impedance with current more 100mA voltage more 20mV.
2. Insulation resistance: After 1 minute 500 VDC, measure the insulation resistance between adjacent contacts of mated and unmated connector components.
3. Voltage withstand: Tested between adjacent contacts of unmated connector assemblies: Voltage: 500 VDC Leakage current: 5.0 mA greater.
4. Insertion force: Connector assemblies in which the measured force is greater must be at 12.5 mm / min.
5. Durability: Mating and unmating connector assembly 750 cycles at a higher rate of 20 times / min.
6. Temperature resistance test: to the temperature of 85 ℃ Shi 2 ℃, time 96 hours for the test. After the test items should be placed in the standard atmospheric conditions for 1 hour before measuring action
7. Constant temperature and humidity: 90% ~ 95% RH, temperature 40 ℃ earth 2 ℃, 96 hours for the test. After the test articles should be placed in the standard atmospheric conditions for 1 hour before the measurement of action
8. Smoke test: 5 earth 1% salt water concentration; temperature 35 +1 + ℃ / -2 ℃, time 16 hours for the test.
9. Tin-eating properties: the terminal foot will be immersed in Rtype flux 5-10 seconds, and then the terminal foot will be immersed in 245 ° C 士 5 ° C in the tin furnace 4.0 ~ 5.0 seconds
10. Solder resistance: reflow soldering conditions: preheating plating surface temperature should reach 180 ℃, 2 Shi + 03 minutes after the circuit board into the reflow soldering equipment, reflow soldering temperature plating surface temperature is higher for 260 Shi 5 ℃ and stay no more than 10 seconds after the circuit board into the low-temperature soldering place.
