How did connector model designations come about?

I. How is the connector type designation generated? Connector model naming is the basis for customer procurement and manufacturer organization of production. In the connector industry at home and abroad, there are two ideas for product model naming: one is to use the letter code plus numbers, and strive to reflect the main structural features of the product in the model naming. The benefits of this approach is easy to identify, but the arrangement is too long, too complex, with the miniaturization of the connector, to bring a lot of difficulties in printing. At present, this approach is still popular in China, and in some industry standards and even national standards made provisions, such as SJ2298-83 (printed circuit connectors), SJ2297-83 (rectangular connectors), SJ2459-84 (ribbon cable connectors), GB9538-88 (ribbon cable connectors) and so on. Due to the increasing diversity of connector structure, in practice, a naming rule to cover a certain type of connector is increasingly difficult. Another way of thinking is to use a combination of Arabic numerals. This approach has the advantage of simplicity and ease of computerized management and small product logo printing. The major international connector manufacturers are currently using this approach. It can be expected by the manufacturers to develop their own characteristics to reflect the naming approach will gradually replace in the planned economy by the industry as a whole to specify a uniform naming rules.
