Smart devices continue to develop rapidly, whether it is mobile phones, sports bracelets, smart watches, smart wearables, considering their application characteristics, the pogo pin connector used in the product must be designed with vibration issues in mind. In addition, considering the coordination of the entire smart product structure frame and a single pogo pin connector, the increasingly abundant mobile phone applications require more demanding space for the pogo pin connector, and at the same time, the pogo pin connector product volume is required to continue to decrease. This poses a lot of difficulties for the engineer's design.
In view of the vibration problem, a solution that appears now is to use compression technology to replace SMT soldering, or to add pads to prevent damage to the PCB and solder joints. For mobile phones with vibration function and relatively loose structure, pogo pin battery connector is also a better solution. The ability to add effective contacts (ie, dual contacts, similar to the current popular laptop battery connector) is another technology to solve this problem.
In addition, as mobile phone applications increase, various external memories, such as memory sticks and SD memory sticks, will need to be connected. They must be matched with new connectors corresponding to the applications. This is a development direction. The development trend of mobile phones using pogo pin connectors is almost always in line with the multifunctional requirements of mobile phones. For future development, one aspect is standardization, because the pogo pin needs to be linked with some mobile storage devices, such as memory sticks, mobile hard drives, etc., so there must be a specification agreement, that is, interchangeability and compatibility. The other is the transmission speed and anti-interference. Now the signal transmission speed is getting faster and faster, and better shielding is required. Future development will definitely require connectors to be more sophisticated, smaller in size, more stable in current, and faster in signal transmission.
