What are the categories of cell phone connectors?

I. What are the classifications of cell phone connectors?1. Card connectors: mainly 6pin SIM card connectors and T-flash connectors, the direction of development is mainly in and SIM card connector shielding function and thickness of the improvements made to achieve a lower 0.50mm ultra-low thickness, while the card connector products oriented to the direction of multi-functional development, there has been a SIM card connector T-flash connector 2-in-1 products.2. FPC connectors: mainly used to connect the LCD display and driver circuit (PCB).2. FPC connector: mainly used to connect the LCD display and driver circuit (PCB). Currently to 0.4mm pitch products are mainly, 0.3mm pitch products have also been used in large quantities, but with the LCD driver is integrated into the LCD device trend, the number of FPC pins will be reduced accordingly, there are already related products on the market, from the longer term direction of the future FPC connector will be expected to realize and other cell phone components integrated in the cell phone or LCD module framework. 3. I / O connector: contains the connection between the signal and power supply, is the most important access channel for cell phones. Volume reduction and product standardization will be the main direction of future development, the use of circular and MiniUSB connectors, cell phone Micro USB connectors in the European Union and the GSM Association to promote the formation of standardized development, Micro USB connectors appeared in the standardization and customization of the development trend of the combination of headset plug as a connector has also been the same development trend, and then later required to connectors thinner, Board to board connector: cell phone board to board connector development trend is mainly pin pitch and height is getting smaller and smaller, at present is mainly to 0.4mm pitch is the main, will gradually develop to 0.35mm or even smaller, the subsequent requirements of the height of the lower and shielding effect, at the same time, the BTB height is also gradually reduced to 0.9mm.5. antenna connector: As an important function of cell phone calls, it is necessary to mention the connection of the cell phone antenna connector, the industry called Antenna Connector, its function is to connect the cell phone PCB and antenna, its shape will affect the antenna high frequency performance, resulting in signal changes, such as poor signal, unstable, etc., this connector, the high-frequency performance requirements.
