The future development trend of aviation plug
Since the beginning of the 21st century, my country's aviation plug market demand has maintained a high growth trend. Communication equipment, which has a relatively large market share, has become a relatively large consumer group for aviation plugs. There are more connectors used in mobile phones in communication equipment, and the average number used is between 5-9, and the connectors used by different mobile phones are different.
The current mobile phone market has begun to develop in the direction of intelligence and 5G, and its appearance is getting thinner and thinner. The shape is getting more and more beautiful. In order to meet the needs of mobile phones, aviation connectors require multi-function, low height, and good electromagnetic compatibility. At the same time, miniaturization and customization are required.
In the future, aviation plugs will become more and more miniaturized and chip-shaped in terms of volume and dimensions. At present, there are various 2.5Gb/s and 5.0Gb/s connectors with a height of 1.0mm to 1.5mm on the market. Pitch connector pitch currently has 1.27mm, 1.0mm, 0.8mm, 0.5mm, 0.4mm, 0.3mm. At present, semiconductor chip packaging has begun to develop from 0.5mm pitch to 0.25 pitch, which directly leads to the increase of the number of device pins within the IC device and the interconnection between the device and the board from a few hundred to a few thousand. The main technology driving force in level interconnection.
In order to improve the reliability of the connector and ensure the high fidelity of signal transmission, press-fit contact technology will be used for slotted jacks, elastic stranded wire pins and hyperboloid wire spring jacks of circular aviation plugs.
When assembling connectors in the future, the selected assembly technology will be surface mount instead of the current plug-in mounting, so as to avoid the trouble of plugging and unplugging. After the surface mount technology is realized, it will develop to micro-assembly technology and adopt micro-electromechanical system. , It is helpful to improve the technology of connectors and heavy-duty connectors, and the cost performance is very high. It is suitable for the development and needs of the market.
