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.

4. What are the types of rectangular connectors?
1. Pin-type rectangular connector: This is the most common type of rectangular connector. The metal pin is inserted into the interface hole and rotated to tighten to achieve conductive connection.
2. Snap-on rectangular connector: It is fixed with self-locking mechanisms such as spring sheets or clips, and is suitable for use in vibration environments.
3. SMD rectangular connector (SMT type): It is suitable for use in surface mount technology (SMT), which is convenient and fast.
4. Board-to-board rectangular connector: Mainly used for interconnection of board-level and system-level circuits, with the characteristics of high-density connection, low plug-in and pull-out times, and easy maintenance.
5. Wire-to-board rectangular connector: Suitable for the connection of internal signals and power of equipment, can withstand high current and high temperature environments, and has the advantages of easy installation and convenient maintenance.
