According to the "China connector market in-depth research and Development Trend Forecast Report (2022 version)" released by Limu Information Consulting, connector belongs to the new generation of information technology industry, belongs to 1.2 electronic core industry, belongs to 1.2.1 new electronic components and equipment manufacturing subcategory. The connector industry complies with the development trend of networking, intelligence and integration of science and technology, and is the basic and key industry that can promote the development of new technologies in key fields of information technology and the transformation and upgrading of electronic information industry.

Connectors are widely applied in downstream fields, including automotive, communications, consumer electronics, industry, transportation, military aviation, etc., with high specialization requirements in segmsegmentation fields. European and American, Japanese connector multinational companies due to adequate research and development funds and years of technology precipitation, in product quality and industrial scale have a great advantage, these multinational companies often in high performance professional connector products in a leading position, can continue to launch high-end products and lead the development direction of the industry.

The top 10 companies in global connector sales revenue are Tyco Electronics, Amphenol, Molex, Amberford, Foxconn (Taiwan, China), Risun Precision (002475.SZ), Yazaki (Japan), Avionics (JAE, Japan), Pressure Terminal (JST, Japan), Rosenberger (Germany).

The concentration of domestic connector industry is also rising. From 2013 to 2019, the total operating revenue of China's top ten listed connector companies increased from 13.958 billion yuan to 106.485 billion yuan, with a cagR of 40.31%, while the cagR of domestic connector market size was 8.55% during the same period. Domestic top ten listed connector companies operating income growth rate is higher than the domestic connector market growth rate, domestic connector market concentration is on the rise.

The size of China's connector market continues to grow from 2017 to 2021. In 2017, China's connector market size was 124.15 billion yuan, with a year-on-year growth of 15.7%; In 2018, China's connector market size was 135.82 billion yuan, with a year-on-year growth of 9.4%; In 2019, China's connector market size was 147.05 billion yuan, with a year-on-year growth of 8.6%; In 2020, China's connector market size of 161.81 billion yuan, a year-on-year growth of 9.7%; In 2021, China's connector market size of 179.93 billion yuan, year-on-year growth of 11.2%.

From the perspective of the development trend of connector products, enterprises in the industry need to research and develop cutting-edge technology according to the needs of the service industry and the field. In general, the development of connector will be in the direction of high-speed transmission, high frequency, high voltage and high current, high density, miniaturization, wireless transmission and intelligence. "Basic Electronic Components industry Development Action Plan" also indicates the future development trend of connectors. In the field of communications, focus on the development of high-frequency high-speed, low loss, miniaturized photoelectric connectors, and seize the opportunity of global 5G and industrial Internet, focus on promoting high-speed transmission cables and connection components. In the field of new energy vehicles, we will seize the market opportunity of the transition from traditional vehicles to electric, intelligent and connected new energy vehicles and intelligent connected vehicles, and focus on promoting the application of connectors and cable components and other electronic components.
