Pogopin is a precision connector used in electronic products such as mobile phones and is widely used in semiconductor devices for connection.
With the development of smart devices, whether they are mobile phones, sports bracelets, smart watches, or smart wearable devices, considering their use characteristics, vibration issues must be considered when designing products using pogo pin connectors.
In addition, the coordination of the entire smart product structure frame with a single pogo pin connector must also be considered. The increasing abundance of mobile phone applications puts forward strict requirements on the space occupied by pogo pin connectors, and the volume of pogo pin connector products is also shrinking. This adds difficulty to the engineer's design.
For vibration problems, one solution that has emerged is to replace SMT soldering with compression techniques or add pads to avoid damage to the PCB and solder joints. The pogo pin battery connector is also a better solution for phones with vibration and loose construction.
Adding active contacts (i.e. dual contacts, similar to the current popular laptop battery connectors) is another technique to solve this problem. In addition, with the increase in mobile phone applications, various external storage devices, such as memory sticks, SD memory sticks, etc., must be connected with corresponding new connectors, which is a development trend.
The development trend of pogo pin connectors for mobile phones is basically to meet the multi-functional needs of mobile phones.
In future development, the first one is standardization, because pogo pins need to be connected with some mobile storage devices, such as memory sticks, mobile hard disks, etc., so there must be a standard protocol, that is, interchangeability and compatibility.
The second is the transmission speed and anti-interference. Now that signals are traveling faster and faster, better shielding is required. In future development, the connector will be required to be more precise, smaller in size, more stable in current, and more stable in the signal. The transfer speed is faster.
