What are the connectors used in cell phones?

1. Board-to-board connectors: the development trend of board-to-board connectors in cell phones is the pin pitch and height is getting smaller and smaller, at present the main 0.4mm pitch is mainly developed gradually to 0.35mm or even smaller, the subsequent requirements of the height of the lower and have a shielding effect. At the same time, the height of the BTB (board to board connector) is also gradually reduced to 0.9mm. 2.FPC connectors: FPC connectors for LCD display to the driver circuit (PCB) connection, the current 0.4mm pitch products are mainly 0.3mm pitch products have been used in large quantities. With the LCD driver is integrated into the LCD device trend, the number of FPC pins will be reduced accordingly, the market has been related to the emergence of products. From a longer-term direction, the future FPC connector will be expected to achieve with other cell phone components together with the integration of the cell phone or its LCD module on the frame.3. I / O connector: I / O connector is the most important cell phone in and out of one of the channels, including the power supply and signal connection of the two parts of the volume of the reduction and standardization of the product will be the main direction of future development. The use of circular and MiniUSB connectors, cell phones with Micro USB connectors in the EU and GSM Association to promote the formation of standardized development, the current market mainstream is 5pin, due to the various cell phone manufacturers have their own cell phone program, so that Micro USB connectors appeared to standardize and customize the combination of the development trend, while the headset inserted as a connector also had the same development trend, foreign countries in 2012 will be the main direction of development. Trend, in 2012, foreign countries will mainly use MicroUSB as the standard interface for charging, Nokia, Moto and SEMC and other cell phone manufacturers have begun to take substantial steps. Further requirements of the connector thinner, with visual effects and waterproof features, etc. 4. Battery connectors: battery connectors can be divided into shrapnel type and gate type. Battery connector technology trends are mainly miniaturization, new battery interface, low contact impedance and high connection reliability. In the Camera Socket connector, foreign manufacturers such as Nokia and other widely used, Camera Socket connector can provide good electromagnetic shielding of the camera module, easy to repair the camera module, followed by a period of standardization and customization coexist. At the same time in the production of cell phone connectors, testing process, the connector product resistance to insertion and removal and electromagnetic compatibility have raised the requirements. 5. card holder connector: card holder connector to 6pin SIM card holder connector and TF card holder connector is mainly in the future direction of development is mainly in the shielding function of the connector and SIM card and the thickness of the connector to improve, to reach a lower 0.50mm ultra-low thickness, at the same time, the card connectors Products for multifunctional development, the market has appeared SIM card connector + T-flash connector two-in-one products.
