Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

Rectangular connectors are a type of electric/electronic connector which is composed of two or more conductors, either parallel or in an array. The design of rectangular connectors can range from a basic flat surface to a complex intricate interface. This type of connector is most commonly used in electrical and electronic equipment. As with any connector, the purpose of these is to provide an electrical connection between the two components. In addition, rectangular connectors can provide other functionalities such as mechanical and thermal insulation, grounding, mechanical mounting, and low-level signal switches.

Application Fields

Rectangular connectors are used in many different types of devices. One of the most common applications is the connection of circuit boards or PCBs. The pins or contacts on the board are generally arranged into rectangular arrays, allowing for a high density of connections in a very small space. This makes them ideal for use in portable electronic devices or high-density assembly projects. Other applications include high-speed data transmission, power distribution, automotive wiring harnesses, handheld tools, cable assemblies, and medical devices.

Working Principle

Rectangular connectors are designed in such a way that they ensure a reliable electrical contact between the two components they are connecting. This is usually done by having rigid contacts pinched between metal layers. This creates a tight hinge or "pinch" which is strong enough to withstand harsh environments. The size of the gaps between each of these contacts is carefully considered, so that all connections are complete and no loose contact points are left. In some cases, a protective insulation material is added to make sure that the connection does not corrode over time.

The design of the contacts is also very important, as they need to be compatible with the voltage and current of the components in order to create a safe and reliable connection. For higher voltage and current levels, insulation and additional metal layers may be needed to ensure safe operation. Additionally, the physical design of the connector is determined based on the size and shape of the components being connected. This can be determined by taking measurements of the components and their connection points and then designing a suitable connector accordingly.

Conclusion

Rectangular connectors have a wide range of uses and applications in the electrical and electronic industry. Their ability to create tight and reliable connections in a compact space makes them ideal for use in many different types of devices. These connectors are designed to ensure that all connections are complete and safe, by utilizing specific contact pin designs and insulation techniques. The design of the connector itself is typically based on the size and shape of the components being connected, as well as the voltage and current levels that need to be supported.
