Connector model named customers to purchase and organize production according to the manufacturer.
In the connector industry at home and abroad, product designations, there are two ideas: one is with a letter code and a number of means, to reflected in the designations for the main structural characteristics of the product. The benefit of this approach is easy to identify, but is too long and too complex, with the miniaturization of connectors, and brought to print a lot of difficulties.
Currently popular this approach, and in certain industry standards or even makes provisions in national standards, such as SJ2298-83 (printed circuit connectors), the SJ2297-83 (rectangular connectors), pin SJ2459-84 (ribbon cable connector), GB9538-88 (ribbon cable connector).
Due to the increasingly diversified structure of connector, using a naming convention in practice cover a certain type of connector has become increasingly difficult. Another idea is to use Arabic numerals combination. This approach has the advantage of simplicity, easy computer management and small logo printed products. Major connector manufacturer in the world are currently using this method. Reflection from various manufacturers can be expected to develop unique naming method will be gradually replaced by the industry-wide unified regulations under the planned economy system some means of naming.
