Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors are a type of electrical and mechanical device used to join components. They are used in a variety of applications, from consumer electronics to industrial machinery. Headers are the male component of the rectangular connector and are fitted with pins that plug into receptacles, which are the female component of the pair. Female sockets are also available for connecting with other female sockets, enabling the connection of multiple devices simultaneously. One such product is the 643237-1 rectangular connectors. This article will explain the field of application and working principle of this product.

Field of application

The 643237-1 is suitable for a vast range of electrical applications. From consumer electronics to small scale industrial applications, the 643237-1 is designed to be used in high-speed data transmission from printers, computers, and other digital devices. It is also suitable for use in consumer applications such as headphones, cameras, and mobile phones. With a nominal operating temperature range of –20 °C to +105 °C, the 643237-1 is designed for use in challenging environments.

The 643237-1 is also suitable for use in automotive applications. With a UL 94V-0 Flammability Rating, the 643237-1 is perfect for use in cars, trucks, and other automotive equipment. Additionally, the connector is also compliant with ISO 9001 and IEC60601-1 standards, making it suitable for use in medical and healthcare applications.

Working principle

The 643237-1 is an industry-standard two-part rectangular connector. The male header portion of the connector is fitted with two rows of millimeter-spaced pins and includes an internal polarization key. This special key limits misalignment of the male and female components and ensures that the pair only forms a complete circuit when connected correctly. The female receptacle portion of the connector has two rows of free-hanging holes that accept the pins on the male header component. All of the pins and receptacles of the 643237-1 are plated with gold, which helps to ensure accurate, reliable connections.

Furthermore, the 643237-1 includes four unique features that enable the connector to remain firmly connected. The first is a three-pronged locking tab that acts as a latch mechanism to ensure the two components remain securely interconnected. Secondly, the connector is fitted with external grounding clips that help to reduce electro-magnetic interference. Thirdly, the connector is designed with an integral strain relief, which serves to protect the wires from being pulled out of the plug. Lastly, the 643237-1 is fitted with an EMI shield, which helps to reduce interference with nearby devices.

In conclusion, the 643237-1 is a versatile, reliable, and cost-effective solution suitable for a multitude of electrical applications. From consumer electronics to automotive uses, the 643237-1 contains cutting-edge features such as a polarization key, grounding clips, a strain relief, and an EMI shield to help maintain consistent connections with minimal electrical interference.
