The technological trends of pogo pin connectors are mainly miniaturization, new battery interface, low contact impedance and high connection reliability
1. FPC pogo pin connector
The FPC pogo pin connector is used to connect the LCD display to the drive circuit (PCB). Currently, 0.4mm pitch is the main product, and the 0.3mm pitch product has also been widely used. With the recent trend of LCD drivers being integrated into LCD devices, the number of FPC pins will be reduced accordingly, and related products have appeared on the market. Looking from a longer-term perspective, the future FPC pogo pin connector is expected to be integrated with other mobile phone components on the frame of the mobile phone or its LCD module.
2. Board-to-board pogo pin connector
The development trend of the mobile phone mid-board-to-board pogo pin connector is that pin pitch and height are getting smaller and smaller. Currently, it is mainly 0.4 mm pitch, and it will gradually develop to 0.35 mm or less. Follow-up requirements are lower and shielded. effect. At the same time the height of the BTB (board-to-board pogo pin connector) is gradually reduced to 0.9mm.
3, I/O pogo pin connector
The I/O pogo pin connector is one of the most important access channels in mobile phones, including the connection of power supply and signal. The reduction in volume and product standardization will be the main directions for future development. Nowadays, circular and Mini USB pogo pin connectors are widely used. Mobile phones use the Micro USB pogo pin connector under the impetus of the European Union and the GSM Association to gradually form a standardized development. The current mainstream market is 5pin, since each mobile phone manufacturer has its own The mobile phone solution has led to the development trend of the combination of standardization and customization of the Micro USB pogo pin connector. At the same time, the earphone has been used as a connector for the same development trend. In 2012, foreign countries will mainly adopt MicroUSB as the standard interface for charging. Nokia, Moto Mobile phone makers such as SEMC have begun to take substantial steps. Further requirements are for thinner connectors, visual effects, and waterproofing.
4, card type pogo pin connector
The card type pogo pin connector is mainly composed of a 6-pin SIM card pogo pin connector and a T-flash pogo pin connector, and the future development direction is mainly to improve the shielding function and thickness of the pogo pin connector of the SIM card to a minimum of 0.50. The ultra-low thickness of mm, while the card pogo pin connector products are oriented toward multi-functional development, the market has appeared SIM card pogo pin connector + T-flash pogo pin connector combo product.
5, battery pogo pin connector
The battery pogo pin connector can be divided into shrapnel type and guillotine type. The technical trend of the battery pogo pin connector is mainly miniaturization, new battery interface, low contact resistance and high connection reliability.
6, Camera Socket pogo pin connector
The Camera Socket pogo pin connector is widely used by foreign manufacturers such as Nokia. The Camera Socket pogo pin connector can provide good electromagnetic shielding for the camera module, which facilitates the maintenance of the camera module, and standardization and customization coexist for a period of time. At the same time, in the process of production and testing of mobile phone pogo pin connectors, plug connector and electromagnetic compatibility of the connector products have increased.
