Rectangular connectors are widely used in the industry because they offer greater flexibility and reliability than circular connectors. The 91687-318LF is a rectangular connector commonly used in various applications from USB to automotive. This article will discuss the application fields and working principle of the 91687-318LF rectangular connector.

Applications

The 91687-318LF connector is primarily used in USB applications, allowing for an electrical connection from the host device to the device (such as a printer, flash drive, or smartphone). The connector is also used in automotive applications such as automotive audio/visual systems, which allow audio and video signals to be transmitted from the automotive head unit to the various components of the system. Additionally, the 91687-318LF connector can be used in communications applications where electrical signals need to be transmitted from one device to another. Some examples include satellite and wireless communication systems.

Working Principle

The 91687-318LF connector consists of two parts: the male pin and the female header. The male pin is a metal strip with a row of pins extending from one end, while the female header is a plastic strip with corresponding holes for each pin. When the two pieces are mated together, the pins on the male pin make an electrical connection with the pins in the corresponding holes of the female header. This creates a secure connection for the transfer of electrical signals. The connector is also designed with an EMI shielding feature for protecting signals from interference.

In addition to the electrical connection, the 91687-318LF connector also relies on physical contacts to provide tensile strength and secure the two pieces together. The physical contacts are located in the form of small metal fingers that are spread apart in the female header and slide together when the male pin is inserted. This creates a tight connection that can withstand repeated mating and un-mating cycles. The 91687-318LF connector is also rated for up to five insertion/extraction cycles.

Conclusion

The 91687-318LF connector is a reliable and versatile rectangular connector used in a variety of applications from USB to automotive. The connector is designed with a male pin and female header that make an electrical connection when mated together, as well as physical contacts that provide tensile strength and secure the two pieces. This connector is also designed with an EMI shielding feature and is rated for up to five insertion/extraction cycles, making it an ideal choice for a variety of applications.
