1. What is a rectangular connector?
A rectangular connector is a connector with a basically rectangular shape and a basically rectangular mating surface. It is also an important category in the connector family. There are many varieties and specifications, and it is also widely used. It should be pointed out that the classification of rectangular connectors and printed circuit board connectors, strip connectors, and ribbon cable connectors is sometimes not strictly defined. For the same type of connector, some manufacturers classify it as a rectangular connector (approximately rectangular in shape), some as a printed circuit board connector (used in printed circuits), some as a strip connector (approximately long in shape), and some as a ribbon cable connector (connected with a ribbon cable). It is widely used in indoor cable connections, internal connections of equipment, and occasions where multiple rows of assembly are required.
