Rectangular connectors are the main type of in-line electrical connectors. These connectors are constructed from a single piece of conductive material with multiple pins arranged in a row. The pins are usually arranged in a particular pattern, allowing them to be quickly inserted into a mating connector. The two common types of rectangular connectors are headers and specialty pins.

Application Field

Rectangular connectors are used in a wide variety of applications across many different industries, from medical to automotive. They are used for wiring harnesses, printed circuit boards, modular fans, and much more. These connectors are designed to provide high-density connection points with superior electrical and mechanical performance.

Headers are typically used in applications requiring large quantities of signal, power, and ground connections, such as printed circuit boards. Additionally, they may use specialized pin patterns for added flexibility. Specialty pins, on the other hand, are used in more specific applications, such as automotive electronics. They provide better strain relief, electrical insulation, and mating strength than traditional terminal blocks.

Working Principle

Rectangular connectors are designed to provide a reliable electrical connection between two or more cables or components. This is achieved through the use of metal pins, which are inserted into the connector and make contact with the adjoining cable’s conductors. The pins may be either soldered to the cable’s conductors, welded, or crimped for a secure connection.

In order for the connection to be reliable, the connector must be designed in such a way that the pins remain securely connected to the cable. This is achieved through the use of contact surfaces, such as crimp tabs, and internal locking mechanisms which prevent the pins from loosening or becoming disconnected. Additionally, the connectors must be appropriately rated for the application in which they are used.

Rectangular connectors are designed to be durable and reliable, capable of withstanding exposure to toughness environments. The connectors are typically made of plastic, which offers superior resistance to corrosion, chemical exposure, and thermal shock. Additionally, the connectors may be designed with strain relief features to protect the wire from mechanical stress, and insulated pins and housings to prevent the connector from shorting out.

Rectangular connectors are an essential component of many electronic systems and are used for a variety of applications. They provide superior electrical and mechanical performance, as well as reliable connections between components and cables. These connectors are available in a variety of sizes and styles to meet the needs of any application.
