Rectangular connectors, also known as housings, are one of the most popular types of electrical connectors. They are used in a wide variety of applications, from consumer electronics to industrial equipment. In order to understand the design and use of these connectors, it is important to first understand the basics of their construction and function. This article will discuss the application field and working principle of rectangular connectors.

Application Field of Rectangular Connectors

Rectangular connectors are used in a variety of applications, both commercial and industrial. They are commonly used in consumer electronics such as cell phones, laptops, and tablets, as well as in industrial equipment such as motors and pumps. In addition, they are often used in medical, aerospace, and military applications.

Their popularity and widespread use is due in part to their versatility and ability to serve many purposes. For example, a single rectangular connector can be used to connect multiple components or wires, reducing the need for multiple discrete connectors. Additionally, they are much more reliable than competing types of connectors.

Working Principle of Rectangular Connectors

The working principle of rectangular connectors is based on two basic functions. The first is a contact force which is applied between two mating pins on the connector. This force creates an electrical connection between the pins. The second function is a fastening force which holds the connectors in place, preventing them from moving or disconnecting during application.

The contact force is created by compressing the contact pins against each other. As the pins are compressed, electrical contact is established and a current can be passed between them. The fastening force is created by the housing which is used to support the pins. The housing allows for a secure and reliable connection, as it prevents the pins from becoming loose or disconnected.

In addition to these two functions, the design of the housing also plays an important role in the performance and reliability of the connector. The housing helps to protect the contact pins from environmental conditions such as dust, moisture, and extreme temperatures which can cause them to corrode or become damaged.

Conclusion

Rectangular connectors, also known as housings, are one of the most common and versatile electrical connectors today. They are used in a variety of applications, from consumer electronics to industrial equipment. The working principle of these connectors is based on two basic functions: contact force and fastening force. The contact force establishes an electrical connection between two mating pins on the connector, while the fastening force holds the connectors in place, preventing them from moving or disconnecting. The design of the housing also plays an important role in ensuring the reliability and durability of the connection.
