Powercon Plug is used in the aerospace field, especially in large quantities. Generally, an aircraft can use hundreds or even thousands of Powercon plugs, involving tens of thousands of lines. In order not to affect the normal operation of the aircraft circuit, to ensure the safe operation of the aircraft, the Powercon plug not only needs to have the general performance requirements, but also requires good contact performance, very good reliability, and has the advantages of easy maintenance.

With the increasing demand for vehicle comfort, more and more electrical connectors are used in the automotive field. As connector technology continues to improve, the connectors used by a car in the future will be far greater than today's use, a car will use about 600-1000 electrical connectors. And with the widespread use of electronic equipment in the automotive field, the number of pin-to-pin connection points of various connectors will increase accordingly, which will exceed 10,000. If the pin-to-pin connection of one connector fails, it will cause various use problems of automobiles, and serious safety driving problems, therefore, improve the electrical connection. The reliability of Audio Power Connector is very necessary.

Powercon plug is used in the field of communication equipment, which can effectively solve the interconnection problems among optical fiber, optical cable, wire, various electronics, electrical and optical fiber, and ensure the normal operation of communication equipment.

In recent years, China's Powercon plug market demand has maintained a high-speed growth trend, occupying the largest market share of communications equipment, Powercon plug has become the largest consumer group. Mobile phones use the largest number of connectors in communications equipment, the average number of use is about 5-9, and different mobile phones use different connectors.

Now mobile phones are developing towards intelligence and 3G, and their shapes are becoming more and more thin. To meet the needs of mobile phones, the aviation plug requires multi-functional, low-altitude, with good electromagnetic compatibility, while miniaturization and customization coexist.

In the future, the size and shape of the Audio Power Connector will be more and more miniaturized and chip-like. At present, there are 2.5Gb/s and 5.0Gb/s connectors with 1.0mm to 1.5mm height in the market, and the spacing of the fine spacing connectors is 1.27mm, 1.0mm, 0.8mm, 0.5mm, 0.4mm and 0.3mm. At present, semiconductor chip packaging has begun to develop from 0.5mm to 0.25, which directly leads to the increase of the number of device pins in IC devices and interconnection between devices and boards from hundreds to thousands, and this technology will become the main driving force of interconnection technology at all levels in the future.

Some new connectors, such as push-in connectors, use blind matching technology, no longer need to use cables, installation and disassembly is very convenient, can be replaced on the spot, insertion speed, smooth separation, more importantly, to obtain good high-frequency characteristics, which will be the future of spacecraft commonly used products.

In order to improve the reliability of the Audio Power Connector and ensure the high fidelity of the signal transmission, the press-fit contact technology will be adopted for slotted sockets of circular Powercon plugs, elastic stranded pins and hyperbolic spring sockets.

When assembling connectors in the future, the assembling technology chosen is surface mounting instead of plug-in mounting, thus avoiding the trouble of plug-in and pull-out. After realizing surface mounting technology, it will develop to micro-assembly technology. The adoption of micro-electro-mechanical system is conducive to improving the connector technology, and the cost-effectiveness is very high.
