The housing of Connector shall have a mechanical structure to reliably mount and secure the Connector on PCB before soldering the pins. In other words, it can’t just rely on the Connector Pins to withstand the force from user when plugging in or take out. For Connector located in an user access area, the mechanical structure shall be able to withstand a steady force of 30 N ± 3 N for a period of 5 seconds
