1. Mechanical properties. USB FTDI Cable IP67 waterproof round connector Manufacturers tell you that plugging force is an important mechanical property in terms of connection function.
USB FTDI Cable IP67 waterproof round connector Manufacturers tell you that the insertion force is divided into the insertion force and the pull-out force (the pull-out force is also called the separation force), and their requirements are different. The insertion force should be small (so there is a low insertion force LIF and no insertion force ZIF structure), and if the separation force is too small, it will affect the reliability of the contact.

USB FTDI Cable IP67 waterproof round connector Manufacturers tell you that another important mechanical property is mechanical life. Mechanical life is actually an indicator of durability, also known as mechanical operation. It takes one insertion and removal as a cycle, and judges whether its connection function (such as contact resistance value) can be completed normally after the specified insertion and removal cycle.
USB FTDI Cable IP67 waterproof round connector Manufacturers tell you that the insertion force and mechanical life are related to the contact structure (positive pressure), the coating quality of the contact part (sliding friction coefficient), and the dimensional accuracy (alignment) of the contact part.
3. Electrical performance. USB FTDI Cable IP67 waterproof round connector Manufacturers tell you that the main electrical properties of waterproof connectors include contact resistance, insulation resistance, and electrical strength.
USB FTDI Cable IP67 waterproof round connector Manufacturers tell you that insulation resistance is an index to measure the insulation performance between contacts and between contacts and the shell, and its size is between several hundred megohms and tens of megohms. Electric strength, or withstand voltage, and dielectric withstand voltage, is the ability to withstand the rated test voltage between contacts or between contacts and the enclosure. Contact resistance High-quality electrical waterproof connectors should have low and stable contact resistance, ranging from a few milliohms to tens of milliohms.
The above is the USB FTDI Cable IP67 waterproof round connector manufacturer's introduction and analysis of the mechanical and electrical properties of the waterproof round connector, hope it helps you.
