Waterproof USB socket_waterproof USB connector, as the name implies, is a USB socket and connector with a waterproof function. There are many kinds of USB sockets, and the USB socket mentioned by the editor is not a finished plug socket, but a semi-finished product, a kind of component. In fact, the waterproof USB socket mentioned here is a waterproof USB connector, but for some people The name is different.
Elecbee specializes in providing waterproof USB sockets. In addition, there are many electronic components. Let's introduce the performance and function of the waterproof USB socket.
Waterproof USB socket_basic performance of waterproof USB connector:
1. Electrical properties: The main electrical properties of USB sockets include contact resistance, insulation resistance, and electric strength.
Second, environmental performance: the environmental performance of the USB socket Common environmental performance includes temperature resistance, humidity resistance, salt spray resistance, vibration, and impact performance.
3. Mechanical performance: including the mechanical life of the USB socket and the USB connector. It takes one insertion and one extraction as a cycle to determine whether the USB socket can normally complete its connection function after the specified plug cycle. As a basis for judgment. Mechanical performance As far as the connection function is concerned, the insertion and extraction force is an important mechanical performance. Insertion and extraction force is divided into insertion force and extraction force (extraction force is also called separation force), the requirements of the two are different.
Waterproof USB socket_The function of the coating on the waterproof USB connector
1. The surface of the common metal coating is covered with an oxide film to ensure that the oxide film is broken when the waterproof USB socket is matched, and the contact interface is no longer oxidized.
Second, the precious metal coating is relatively simple to contact the metal that produces the interface and maintains the stability of the impedance of the contact interface.
Third, the coated USB socket is not easy to be oxidized and vulcanized.
Fourth, play a role in optimizing the electrical performance of the USB socket, build production and maintain a stable USB socket impedance.
5. It can improve the mechanical properties of the USB socket to a certain extent and enhance its wear resistance.
Waterproof USB socket_development direction of waterproof USB connector
Waterproof USB socket_The development of a waterproof USB connector should be the development direction of high-speed transmission, miniaturization, high density, and high frequency.
1. High-speed transmission means that modern computers, information technology, and network technology require that the time-scale rate of signal transmission reaches the megahertz frequency band, and the pulse time reaches sub-milliseconds. Therefore, a high-speed transmission waterproof USB socket_waterproof USB connector is required.
2. Miniaturization means that the center spacing of the waterproof USB socket is smaller.
3. High density means that the waterproof USB socket can achieve a large core count. The total number of effective contacts of the high-density PCB waterproof USB socket reaches 600 cores, and the dedicated device can reach up to 5000 cores.
4. The high frequency is to adapt to the development of millimeter-wave technology, and the radio frequency coaxial waterproof USB sockets have entered the millimeter-wave working frequency band.
