Wire to Board Connectors

Rectangular Connectors - Board In/Direct Wire to Board

Definition:
Rectangular connectors, specifically designed for board-in or direct wire-to-board applications, are electrical connectors that facilitate the connection between a printed circuit board (PCB) and external wiring or another PCB. These connectors come in a rectangular shape and are characterized by their robustness and ease of use in various electronic devices.

Function:
1. Signal Transmission: They enable the transmission of electrical signals between the PCB and external devices or circuits.
2. Power Supply: They provide a means to supply power to the PCB from an external power source.
3. Data Transfer: In some cases, they can also be used for data transfer between devices.
4. Mechanical Support: They offer mechanical support and stability to the connected components.

Applications:
1. Consumer Electronics: Used in devices like smartphones, tablets, and laptops for internal connections.
2. Industrial Equipment: Employed in machinery and automation systems for reliable and durable connections.
3. Automotive: Found in vehicles for connections to sensors, control units, and infotainment systems.
4. Medical Devices: Utilized in medical equipment for secure and precise connections.

Selection Criteria:
1. Contact Density: The number of pins or contacts the connector can accommodate.
2. Current Rating: The maximum current the connector can safely handle.
3. Voltage Rating: The maximum voltage the connector can withstand without damage.
4. Environmental Resistance: The ability to resist moisture, dust, and other environmental factors.
5. Mechanical Strength: The durability and robustness of the connector's construction.
6. Size and Shape: The physical dimensions and form factor to fit the specific application.
7. Compatibility: Ensuring the connector is compatible with the PCB and external devices.
8. Cost: Balancing the cost of the connector with the performance and reliability requirements.

In summary, rectangular connectors for board-in or direct wire-to-board applications are essential components in electronic assemblies, providing reliable and efficient connections for signal, power, and data transmission. When selecting these connectors, it is crucial to consider factors such as contact density, current and voltage ratings, environmental resistance, mechanical strength, size, compatibility, and cost to ensure optimal performance in the intended application.
