Due to the increasingly diverse structure of connectors, new structures and application areas continue to emerge, and it has become difficult to adapt to trying to solve the classification and naming problems with a fixed model.
1. According to the nature of use
External connectors (for external casings) and internal connectors (for internal casings).
2. According to the level of the connector
●Level 1. Interconnection of components to packages (DEVICE TO PACKING):
Refers to the connection between IC CHIP and pins.
●Level 2. Package-to-substrate interconnection (COMPONENT LEAD TO CIRCCUITRY):
Refers to the connection between COMPONENT and the PC board.
●Level 3. Board to Board connection (Board To Board):
Refers to the interconnection between PC boards and PC boards.
●Level 4. Subsystem-to-subsystem connection (SUBASSEMBLY TO SUBASSEMBLY)
●Level 5. The connection between subsystems to I/O (SUBASSEMBLY TO I/O PORT).
●Level 6. System-to-system connection (SYSTEM TO SYSTEM).
3. According to the processing method
Crimping type (Crimp Type), crimping type (I.D.C Type) are also called piercing type, welding type (Solder Type), zero insertion type (Z.I.F Type).
4. According to the way of use
Wire-to-board connectors, board-to-board connector wires, wire-to-wire connectors, sockets, input and output connectors.
5. According to the form
PCB board connectors, flat cable connectors, coaxial cable connectors, embedded connectors, pinch connectors, circular connectors, angled connectors, and printed wiring board connectors.
6. According to the structure
General connectors, moisture-proof and waterproof connectors, environment-resistant connectors, air-tight connectors, fire-resistant connectors, and water-resistant connectors.
7. According to the working frequency
Low frequency and high frequency (bounded by 3MHz).
8. From its versatility and related technical standards, connectors can be divided into the following categories (subcategories):
①Low frequency circular connector;
② Rectangular connector;
③Printed circuit connector;
④ RF connector;
⑤ Optical fiber connector.
