173866-4

Rectangular connectors, also known as headers, male pins, are devices that are designed to provide an electrical connection between two components or to board-level interconnections in electronic circuits. The 173866-4 is a specifically designed rectangular connector often used in the aerospace, automotive, medical, telecommunications and consumer electronics industries. This article is aimed to explain the application field and working principle of 173866-4 rectangular connector.

The 173866-4 rectangular connector is a one-piece, two-row, two-column rectangular connector designed to provide consistent power supply in harsh environments. It is often used in areas where robustness and high reliability is required, such as the aerospace industry. The dimensions of the 1738664 are 31.3 mm x 13.0 mm x 8.4 mm, with a spacing of 7.25 mm and a pitch of 2.50 mm. In addition, it has an operating temperature of -55°C to 125°C.

The number of contacts in the 173866-4 varies according to its application. Commonly, it has 28 contacts, but there are other configurations available, such as 4 contacts, 14 contacts, or 48 contacts, among others. These contacts are usually made of phosphor bronze or beryllium copper, with gold or tin plating, for even better performance. The 173866-4 is a male connector, and a female counterpart must be used in order to make the connection.

The working principle of the 173866-4 connector is based on a contact insertion system that allows it to be mounted rapidly and securely. The contact is air-clinched between two plastic parts, creating a stable connection that does not depend on hardware. This system provides an increased pull-out strength, which is very important for secure connections in harsh environments. In addition, it has an interference-proof design, which allows it to be exposed to electromagnetic radiation without suffering any damage.

The 173866-4 connector is ideal for applications that require high reliability and robustness, such as those in the aerospace, automotive, medical, telecommunications, and consumer electronics industries. It is particularly suitable for applications where the contacts are located in tight spaces. In addition, it is a cost-effective solution, since its air-clinched design allows for rapid and secure contact insertion.

In conclusion, the 173866-4 rectangular connector is an extremely robust and reliable device that is ideal for applications requiring robustness and high reliability. It is a cost-effective solution, since its air-clinched design and interference-proof design allows for rapid and secure contact insertion and gives it protection from electromagnetic radiation respectively. The 173866-4 connector is therefore widely used in the aerospace, automotive, medical, telecommunications and consumer electronics industries for its superior performance.
