Development of Coaxial Connectors Industry

The upstream raw materials of the coaxial connectors industry are non-ferrous metals, rare and precious metals, plastic materials and other auxiliary materials. Among sma female connector, non-ferrous metals are mainly used to make connection terminals. In order to avoid excessive obstruction or degradation of signals during transmission, the terminals mostly use sma connector plates such as brass, beryllium copper, phosphor bronze, etc. as raw materials; rare and precious metals are used for electroplating Materials, the most commonly used are gold, palladium, nickel, silver, etc.; plastic raw materials are mainly PBT, PCT, LCP, PPS, NYLON resin, etc., which are used to make the connected shell part; auxiliary materials are mainly chemical reagents required for electroplating , Including sma female connecto, glass and other shell parts. The cost of raw materials accounts for about 30% of the connector product cost. Among them, non-ferrous metals and rare precious metals account for the largest proportion of the cost of connectors, followed by plastic raw materials and other auxiliary materials.

The main application areas downstream of the coaxial connectors are automotive, communications, sma connector, industry and other fields, accounting for 71% of the total. The top four application areas of connectors are automotive (23%), communications (21%), consumer electronics (15%), and industry (12%), occupying a total of 71% of the market share, followed by transportation (7%) , Military aviation (6%), and other fields such as medical, commercial and office equipment account for 16% of the total.

The basic criteria for evaluating coaxial connectors include mechanical performance, electrical performance, and environmental performance. Mechanical performance mainly refers to insertion force and mechanical life. Insertion and extraction sma female connecto is divided into insertion force and extraction force (extraction force is also called separation force), the requirements of the two are different. There are provisions for maximum insertion force and minimum separation force in the relevant sma connector, which shows that from the point of view of use, the insertion force should be appropriately small (there are structures with low insertion force LIF and no insertion force ZIF), and if the separation force is too high Small will affect the reliability of the contact. Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a durability index. It takes one coaxial connectors insertion and one extraction as a cycle, and whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and sma connector is used as the judgment basis. The plug-in force and mechanical life of the connector are related to the contact structure (positive pressure), the coating quality (sliding friction coefficient) of the contact part, and the dimensional accuracy of the contact arrangement (alignment).
