The so-called connector is to connect two or more objects to a piece of media such as sockets, sockets, terminals, etc. The mobile phone connector is an important electronic component in the mobile phone. Its quality is directly related to the quality of the mobile phone and the reliability of its use. In the mobile phone, its main components include: membrane button, subminiature button switch, slide switch, mobile phone built-in antenna, PDA smart phone line, I / O system connector, data and sound I / O system connector, SIM card base, mobile phone battery connector, RF connector, spring connector, with headphone cable plug, charging jack, rectangular connector, mobile phone accessory cable and Plug jacks, connectors, etc. If the wrong selection and use of the connector can cause the system to fail to work properly, and lead to a series of chain reactions such as product recall, circuit board damage, rework and repair, and then affect product sales, resulting in customer loss, so the connector is a very important field in the mobile phone industry.
From the perspective of the global mobile phone market, the development prospect of this industry is very optimistic. Although the global financial crisis has a great impact on the entire mobile phone industry, causing a serious decline in the industry as a whole. But from the perspective of market segmentation, at present, the global mobile phones are moving towards the direction of intelligent development. The introduction of iPhone and gpphone has driven the demand of global consumers to use broadband mobile network to directly access the Internet for data applications, and also promoted the market demand of global smart phones and high-end mobile phones. Its huge influence makes mobile upstream enterprises around the world see the direction of development.
A big growth point of China's mobile phone market in the future will come from smart phones. With the expansion of China's 3G market and the strong demand for smart phones, these will bring profound impact and change to the mobile phone connector industry. And 2009 is the first year of China's 3G development. Because China's 3G market started later than the global market, the pent up 3G market demand for several years will make consumers' demand for replacement, new applications and new services have exceeded the normal growth. This is a very promising opportunity for handset connector manufacturers.
Differentiated phone connector types
At present, most of the after-sales quality problems of mobile phones are mostly related to connectors. The types of connectors used in mobile phones vary slightly according to their products. The average number of connectors used is about 5-9. The product types can be divided into internal FPC connector, board to board connector, external I / O connector, battery, SIM card connector, camera socket, etc.
FPC connector
FPC connector is used to connect LCD display to drive circuit (PCB). At present, 0.4mm pitch products are mainly used, and 0.3mm pitch products have been widely used. With the recent trend that LCD drivers are integrated into LCD devices, the number of FPC pins will be correspondingly reduced, and relevant products have appeared in the market. In the long run, FPC connector is expected to be integrated with other mobile phone components in the framework of mobile phone or its LCD module in the future.
Plate to plate connector
The pin spacing and height of the board to board connector in the mobile phone are getting smaller and smaller. At present, it is mainly 0.4mm pitch, which will gradually develop to 0.35mm or even smaller, and the subsequent requirements are lower in height and shielding effect. At the same time, the height of BTB (board to board connector) is gradually reduced to 0.9mm.
I/O connector
I / O connector is one of the most important access channels in mobile phones, including the connection of power supply and signal. The reduction of volume and product standardization will be the main development direction in the future. At present, circular and MINIUSB connectors are widely used, and the current market mainstream is 5pin.
Card connector
The card connector is mainly composed of 6pin SIM card connector and T-Flash connector. The development direction in the future is to improve the shielding function and thickness with SIM card connector, to reach the minimum of 0.50mm ultra-low thickness. At the same time, the card connector products are oriented to multi-functional development, and there are two in one products of SIM card connector and T-Flash connector in the market.
Battery connector
Battery connector can be divided into spring type and knife type. The trend of battery connector technology is miniaturization, new battery interface, low contact impedance and high connection reliability.
In terms of camera socket connector, foreign manufacturers such as Nokia are widely used. Camera socket connector can provide good electromagnetic shielding for camera module, which is convenient for maintenance of camera module. In the future, standardization and customization coexist. At the same time, in the process of production and testing of mobile phone connector, the requirements of plug-in resistance and electromagnetic compatibility of connector products are improved.
Standard and environmental protection are the key to the development of mobile phone connector
Because each mobile phone manufacturer has its own mobile phone scheme, the micro USB connector has the development trend of combination of standardization and customization. At the same time, the headphone plug-in connector has the same development trend. In 2012, foreign mobile phone manufacturers will mainly use microusb as the standard interface for charging. Nokia, moto, SEMC and other mobile phone manufacturers have begun to take substantive steps. In the future, the connector is required to be thinner, with visual effect and waterproof function. Now it is generally agreed in the industry that the mobile phone plug-in components should be standardized as much as possible, especially the standardization of I / 0 connector. All kinds of interfaces should be standardized to ensure the universality of different models. At the same time, the cost can be controlled and the risk of mass production can be reduced.
