The classification of new energy rectangular contact and printed board connectors, strip connectors, and ribbon cable connectors sometimes has no strict boundaries. For the same type of connector, some manufacturers are classified as rectangular connectors (approximately rectangular in shape), some are classified as printed board connectors (used in printed circuits), and some are classified as strip connectors (approximately long in shape). bar), and some are classified as ribbon cable connectors (with ribbon cables attached). It is widely used for indoor cable connection, internal connection of equipment and occasions requiring multiple rows of assembly.

The main supporting fields of new energy rectangular contacts are transportation, communication, network, IT, medical care, home appliances, etc. The rapid development of product technology level in supporting fields and the rapid growth of the market are strongly driving the development of strip connector technology. The bar connector has developed into a serialized and specialized product with a complete range of products, rich varieties and specifications, various structural types, professional direction segmentation, obvious industry characteristics, and standard system specifications.
