Rectangular Connectors provide a number of advantages over traditional round connectors, ranging from improved strength and durability to greater contact density in smaller spaces. The 77319-103-72LF is a popular rectangular connector with an impressive range of features that make it an ideal choice for a variety of applications. In this article, we will examine the application fields and working principle of the 77319-103-72LF.

Features of the 77319-103-72LF

The 77319-103-72LF is a two-piece, polarized, press-fit header connector, designed for use in applications such as automotive, industrial, telecommunications, and medical. It features a rated throughput of 3A/300V, as well as an operating temperature range of -55°C to +105°C. It is also available in both vertical and right-angle configurations. The 77319-103-72LF features an array of stainless steel metal tabs that provide excellent durability and hold the connector firmly in place. The connector also has an insulated plastic body, which further aids in preventing the connector from becoming loose or slipping out and, in turn, damaging the contact pins.

Working Principle of the 77319-103-72LF

The 77319-103-72LF utilizes the concept of "male pins" to establish electrical contact between two devices. Male pins are composed of a number of sections, each of which has an electrical connection that allows the male pins to pass electrical signals from one device to another. Depending on the type of male pins used, the connector can provide a range of current carrying capacities. The 77319-103-72LF features 1.95mm male pins, which can handle up to 3A/300V.

To establish a connection with the 77319-103-72LF, the male pins must first be inserted into the connector. This is accomplished by pressing the male pins into the connector with sufficient force to make contact. As the male pins are inserted, the internal components of the connector, the contact pins, make contact with the male pins. This contact allows electrical energy to be transferred from the male pins to the contact pins, establishing a connection between the two devices.

Application Fields

The 77319-103-72LF is best suited for applications that require high- speed data transfer, such as automotive, industrial, telecommunications, and medical. Its ability to handle a current of 3A/300V and its wide operating temperature range (-55°C to 105°C) make it an ideal choice for the most demanding applications. In addition, its stainless steel metal tabs provide an excellent level of durability, while its insulated plastic body prevents the connector from becoming loose or slipping out, thereby reducing the risk of damage to the contact pins.

The 77319-103-72LF is also well-suited for applications that require a large number of connections in a relatively small space, such as in medical equipment or computer motherboards. Its narrow design allows for higher contact density in areas with limited space, allowing for numerous connections to be established without disrupting the design of the board.

Conclusion

The 77319-103-72LF is a reliable and versatile connector, capable of handling a wide range of applications. Its metal tabs provide a high level of durability, while its insulated plastic body prevents it from loosening or slipping out and damaging the contact pins. In addition, its narrow design and wide operating temperature range make it an ideal choice for applications that require a large number of connections in a relatively small space.
