Rectangular connectors are present in countless electrical and electronic products on the market. Their primary function is to provide an electrical connection between multiple components within a system, enabling power to pass from one component to another. This article will discuss the application fields and working principle of rectangular connectors, specifically focusing on the types known as headers, specialty pin connectors, and other specialty options.

Headers

Headers are one of the most common types of rectangular connectors, and come in a variety of sizes and shapes. These connectors are typically used in a system which requires a large number of connections, such as a wiring harness. They consist of two different types of components, known as pins and headers. The pins are usually made of copper or brass, while the headers are typically made of metal or plastic. In order to make a connection, the pins can be inserted into the corresponding headers, allowing electricity to be transferred between the two components. Headers are also widely used in motherboards, as they provide a secure connection for any peripheral devices.

Specialty Pin Connectors

In addition to the traditional headers, specialty pin connectors can also be used in a variety of applications. These connectors consist of a single row of pins which form an electrical connection between any two components. The pins are usually arranged in an alternating pattern, which increases the number of connections that can be made. Specialty pin connectors are commonly used in automotive, computer, and audio/video applications. They offer a more secure connection than traditional headers, and can be found in many modern electronic products.

Other Specialty Options

Aside from the two types of connectors discussed above, there are a few other types of specialty connectors that are available. These include ribbon connectors, which consist of a series of pins that are arranged in rows, and socket connectors, which are similar to pins but feature additional contacts that allow for more connections. There are also a variety of specialized connectors, such as minijack connectors and MIL-SPEC connectors, which are used in military applications.

Working Principle of Rectangular Connectors

The basic principle of operation for rectangular connectors is the same for all types. The pins on the connector are inserted into the corresponding slots on the other component, creating an electrical connection. For headers and other multiple pin connectors, the pins must be inserted into the appropriate slots in order for the connection to work. On some occasions, a special keying system is used in order to ensure that the pins are inserted in the correct order.

Application Fields

Rectangular connectors are used in many different types of applications. They are commonly seen in automotive, industrial, communication, computer, and consumer electronics, and can be used to provide connections for a variety of tasks. In addition, their popularity makes them ideal choices for applications that require a large number of connections, such as wiring harnesses or audio/video systems.

Conclusion

Rectangular connectors are one of the most common types of electrical connectors on the market, and are available in a variety of shapes and sizes. Headers and specialty pin connectors are two of the most popular types, as they offer a secure and reliable connection between multiple components. The working principle of all rectangular connectors is the same, and they can be used in a variety of applications.
