Terminal blocks, headers, plugs, and sockets are essential components in electrical and electronic systems for establishing reliable connections between circuits. These devices enable signal transmission, power distribution, and system modularity. Their standardized designs ensure interoperability, scalability, and ease of maintenance in complex systems.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Terminal Blocks | Screw/clamp-based connections for high current/ voltage | Industrial control panels, power distribution units |
| PCB Headers | Pin/grid arrays for board-to-board connections | Embedded systems, Arduino shields |
| RJ Connectors | Modular jacks for data/telecom signals | Ethernet networks (RJ45), telephone systems (RJ11) |
| D-Sub Connectors | Multi-pin trapezoidal shells for analog/digital signals | Legacy serial interfaces, industrial sensors |
| USB Connectors | Hot-pluggable interfaces for power/data | Consumer electronics, peripheral devices |
Typical structures include:
| Parameter | Importance |
|---|---|
| Current Rating (A) | Determines power handling capacity |
| Voltage Rating (V) | Defines dielectric strength requirements |
| Contact Resistance (m ) | Impacts signal integrity and power loss |
| Insertion Loss (dB) | Critical for high-speed data transmission |
| Mating Cycles | Indicates mechanical durability |
| Operating Temperature (- C to + C) | Defines environmental tolerance |
Primary industries include:
