USB connector from the surface point of view, the public are not curling, most of the mother is curled, but some machines in order to save space, there are no curling. For the mother seat, there are curls and no curling difference is: first, no curling in order to save space, but also to meet the appearance of the shell panel. Second, there are curling, you can facilitate the male and female inserted when inserted easily. Third, there are curling can be connected with the shell iron shell, more closely contact with.

USB connector development trend

USB connector products "miniaturization", "high-speed mobile" and wisdom is the future development trend. The USB connector industry's future technological innovation is mainly concentrated in:

1.USB connector miniaturization technology

The technology is mainly for the miniaturization of USB connector and development, can be applied to 0.3mm mini USB connector, belonging to MINI USB series of new products. Can be used for multi-contact expansion card slot USB connector, can meet and exceed the multi-contact surface adhesion technology on the contact surface of the strict requirements, high precision, low cost.

2. High frequency and high speed wireless transmission USB connector technology

The technology is mainly for a variety of wireless device communications applications, the scope of application is more extensive.

3. Simulation application technology research

The simulation technology is based on a variety of disciplines and theories, with the computer and its corresponding software such as AutoCAD, Pro / E program stress analysis software as a tool, through the establishment of product model and the corresponding boundary conditions, its mechanical, electrical, And other performance simulation analysis to confirm, thereby reducing the material selection, structural unreasonable factors such as the failure of product development costs, improve the success rate of development, help to achieve complex product applications to provide support.

4.USB connector intelligent technology

The technology is mainly used in the DC series power USB connector products, in the transmission power before the intelligent signal can be detected to ensure that the plug inserted in place after the positive and negative lead and start the power, to avoid the plug when the plug is not in place Conduction contact caused by arc damage, burn the bad consequences of the future enterprises need to develop other products similar to the intelligent technology.

5. Precision USB connector technology

Precision USB connector related to product design, process technology and quality control technology and many other aspects, the main technologies are: ① precision molds processing technology, the use of CAD, CAM and other technologies, the introduction of high precision machining equipment industry, the use of personnel production experience and advanced equipment technology Means to achieve high-precision high-quality mold products; ② precision stamping and precision injection molding technology to achieve all kinds of stamping parts and injection of precision, efficient and stable all-round control and perfect surface quality to ensure product quality; ③ automated assembly technology , Through the application of precision control technology, semi-automatic detection technology applications, to overcome the difficult manual products, improve core competitiveness.

In short, with a variety of different forms of USB connector in the automotive industry, computer communications industry and other applications continue to develop, USB connector average annual growth rate of more than double digits, the market is also expanding.
