Mobile phones connector is important in the electronic components, their quality is directly related to the quality of the phone and the reliability of its use. Mobile phone most of the after-sale quality issues are mostly related to the connector. Mobile phone connector used by different slightly different kinds according to its product, average usage quantity about between 5 ~ 9, products can be divided into internal FPC connector and surface plate, external connection of I/O connector, battery, SIM card connector and CameraSocket, etc.

Affected by 3 g phones and smartphones demand market, phone connector current development direction is: the low level, small pitch, multi-function and good electromagnetic compatibility, standardization and customization co-exist.

FPC connector

FPC connector used for LCD displays links to drive circuit (PCB), currently mmpitch products at 0.4 and 0.3 mmpitch product also has a large number of use. As recently there has been integrated into the LCD LCD drive device of the trend, FPC the pin number will be reduced accordingly, related products have appeared on the market at present. In the longer run direction, FPC connector in the future is expected to achieve integration with other phone parts in the framework of a phone or the LCD module.

Threatening the panel connector

Mobile phone medium plate to plate connector pin spacing and height is the development trend of more and more small, mainly mmpitch 0.4 at present, will gradually develop to 0.35 mm or even smaller, the follow-up requirements height is lower and the shielding effect. The height of the BTB (board to board connector) is gradually reduced to 0.9 mm.

I/O connector

I/O connector is one of the most important access in phones, consists of two parts, the power and signal connection of the decrease of the volume and product standardization will be the main direction of future development. Now USES a more rounded and MiniUSB connector, phone use MicroUSB connector in the European Union and the GSM association and increasingly standardized development, under the impetus of the mainstream of the current market is 5 pin, due to the various phone manufacturers have their own cell phone plan, make the MicroUSB connector in the combination of standardization and customization development trend, at the same time, the development of earphones for connector has the same situation, 2012 foreign will mainly adopt the MicroUSB as charging standard interface, phone manufacturers such as Nokia, Moto and SEMC already substantial strides. Again in the future require the connector is thinner, the visual and waterproof function, etc.

Card connector

Card connector with 6 pinsim card connector and T - flash is given priority to, the future development direction is mainly with the SIM card connector shielding thickness aspects of function and improvement, to meet minimum thickness of 0.50 mm of ultra-low, oriented multifunction card connector product development at the same time, the market there has been a SIM card connector + T - flash 2-in-1 product.

The battery connector

The battery connector can be divided into shrapnel and knife. The battery connector technology trend to miniaturization, new battery interface, low contact resistance and high connection reliability.

In CameraSocket connectors, widely used foreign companies such as Nokia, CameraSocket connector can provide good electromagnetic shielding for camera module, convenient for camera module for repair, further standardization and customization co-exist for a period of time. In the phone connector in the process of production and testing at the same time, the plug and connector products are higher in electromagnetic compatibility requirements.
