Connector model name is based on customer purchases and manufacturers organization of production. Connector industry at home and abroad, product model name, there are two ideas: one is to use letter code plus the number of ways, sought to reflect the major structural features of the product in the model name. The advantage of this approach is easy to identify, but the arrangement is too long, too complicated, with the miniaturization of the connector, to the printing brought many difficulties. At present, still prevalent in this way, and even the national standard provision is made in certain industry standards, such as SJ2298-83 (printed circuit connector), SJ2297-83 (Rectangular Connector), SJ2459-84 (ribbon cable connector device), GB9538-88 (ribbon cable connector) and the like. Due to the growing diversity of the connector structure, in practice, with a naming rule covering a certain type connector increasingly difficult. Another idea is to use a combination of Arabic numerals. The advantage of this approach is simple, easy to manage computers and small product label printing. Major international connector manufacturers are currently using this method. It can be expected by the manufacturer to develop its own characteristics reflect naming approach will gradually replace the planned economy by the industry-wide unified regulations for some naming approach.
