Today, I will explain to you the performance and development direction of waterproof usb connectors.

1. The performance of waterproof usb connector

1. Electrical properties: The main electrical properties of waterproof usb connectors include contact resistance, insulation resistance and electrical strength.

2. Environmental performance: The common environmental performance of waterproof usb connectors includes temperature resistance, humidity resistance, salt spray resistance, vibration and shock resistance.

3. Mechanical properties: including the mechanical life of waterproof usb connectors and waterproof usb connectors, with one insertion and one pull out as a cycle, whether the usb socket can normally complete its connection function after the specified pull out cycle, as the basis for judgment. Mechanical Properties Insertion force is an important mechanical property in terms of connection function. The insertion force is divided into the insertion force and the extraction force (the extraction force is also called the separation force), and the requirements of the two are different.

Second, the development direction of waterproof usb connectors

1. High-speed transmission means that modern computers, information technology and networking technology require the speed of signal transmission to reach the megahertz frequency band and the pulse time to reach sub-milliseconds, so high-speed transmission of waterproof usb connectors is required.

2. Miniaturization means that the center interval of the waterproof usb connector is smaller.

3. High density means that the waterproof usb connector can achieve a large number of cores. The total number of effective contacts of high-density PCB waterproof usb connectors is 600 cores, and the number of special devices can reach almost 5000 cores.

4. The high frequency is to adapt to the development of millimeter wave technology, and the RF coaxial waterproof usb connector has entered the millimeter wave working frequency band.

So today's explanation is here first. I believe that everyone has a certain understanding of the performance and development direction of waterproof USB connectors. Thank you very much for your patient reading.
