Rectangular Connectors refer to electrical connectors that are primarily designed with rectangular pins and cavities in order to fit into printed circuit boards, cables, and various other applications. The 89891-438H is a rectangular connector used widely in the industry, prized for its reliability, durability, and affordability. This article will discuss the 89891-438H’s application field and its working principle.

Application Field and Benefits

The 89891-438H rectangular connectors are designed for use in applications that mandate the protection of circuit boards and components. These connectors are designed to prevent dust, oils, liquid, and other debris from entering the printed circuit board’s components. This is especially important in applications where moisture, hot, or cold environments are present. The connectors employ a hollow moulding technology in order to provide an effective seal between the circuit board’s surface and the connector.

Additionally, the 89891-438H connectors offer superior mechanical strength. The connectors are constructed with an injection moulded plastic to create a sturdy and reliable interface that protects the circuit board’s pins and components. Furthermore, the connectors are highly resistant to various substances such as fuels, grease, fuels, and oil, all of which are typically encountered in industrial applications.

Finally, the 89891-438H connectors are designed to be very cost-effective and easy to use. The connectors can be rapidly installed and reused when needed, making it easier and less expensive for customers to replace parts. Furthermore, the connectors are designed with snap-fit and quick-connect technology to ensure continued connectivity.

Working Principle

The 89891-438H connectors are designed to fit various widths of printed circuit boards and cables. Additionally, the connectors employ a two-piece mechanism in order to ensure a reliable connection between the pins and cavities. The first part of the mechanism involves the pre-valving of the pins and cavities before the connection is made. This ensures that there are no loose connections or misalignments.

The second part of the mechanism is the crimping of the pins and cavities. This process is used to ensure a tight fit for the pins and cavities, which prevents any kind of interference from entering the printed circuit board’s components. Furthermore, the connectors employ a strain relief tab in order to increase the mechanical strength of the connection, ensuring that it does not break under normal circumstances.

The 89891-438H connectors also employ a quick-disconnect mechanism, which allows for the easy and rapid removal of the connectors when needed. This is especially useful for those applications that require a quick replacement of parts, such as electronic repairs. Furthermore, the connectors can also be used with a variety of additional accessories such as wire sealant, strain relief and more in order to increase the reliability of the connection.

Conclusion

In conclusion, the 89891-438H rectangular connectors are a reliable and cost-effective solution for applications that require the protection of circuit boards and components. The connectors are designed to prevent dust, oils, liquids, and other debris from entering the printed circuit board’s components, and employ a two-piece mechanism to ensure a reliable connection between the pins and cavities. Additionally, the connectors offer superior mechanical strength, and are designed to be easy to install and reuse. Finally, the connectors employ a quick-disconnect feature, making them perfect for applications that require a quick and easy replacement of parts.
