Rectangular Connectors provide a reliable way to connect electronic components like motors, switches, relays and so on. The 1-776228-2 is one of the types of rectangular connectors manufactured by Amphenol and used for a wide range of applications. In this article, we will take a brief look at the application field and working principle of this one.

Application Field

The 1-776228-2 by Amphenol is a rectangular connector with two rows of 20 pins each. It is mainly used for board-to-board interconnection. The connector is full-featured with an anti-wicking design to ensure reliable contact and avoid the spread of shorts due to moisture. It has a low profile which allows it to be installed in confined spaces without blocking adjacent ports or components. It can also be used for customized configurations which enable it to perform specific logic operations for complex applications.

The connector has rated current/voltage ratings of 6A/16V, 3.5A/20V and 1.5A/30V. It has an insulation resistance greater than 1x1011 Ohms and a dielectric strength of AC 500V/1min. The contact resistance is less than 30mOhm, and the insertion/withdrawal force required for mating/unmating has a typical value of 0.5Kg/force.

The 1-776228-2 connector is widely used in various industrial, commercial and consumer applications. It can be used for applicance wiring, automotive fuel systems, radio control devices, office equipment, power tools, electric bicycles or electric vehicles, communication equipment, etc.

Working Principle

The 1-776228-2 rectangular connector consists of a male header with 20 pins connected to a corresponding female pin header. The male header pins are shaped in a manner that provides secure mating when plugged into the female pin header. The male pins have a beveled edge that slides into tight slots in the female header, creating a firm electrical connection. This ensures reliable data and power transmission with minimum interference.

The inner surface of the mating area is made of phosphor bronze to ensure better contact and lower contact resistance. The male and female connector halves are additionally kept in contact with each other by the use of a powerful zinc die-cast latch, which is capable of withstanding thousands of plug-unplug cycles. This latch also provides a secure connection, as it prevents the connectors from becoming disengaged even when heavy vibration or shock occurs.

In order to further enhance the reliability of the connection, the contact area on each of the pins is firmly supported by a metal alloy shell to ensure that the current and data transmissions are secure and free from interference. The contacts are also sealed with a wire cover over the male header pins to protect the pins from dust or liquids.

Conclusion

The 1-776228-2 rectangular connector by Amphenol is a reliable and durable connector that is widely used in various industries for a wide range of applications. It has a low profile design and features a powerful latch which ensures a secure connection when plugged into the corresponding female pin header. The contact area on the pins is also supported by a metal alloy shell to provide superior protection and stable current and data transmissions. As such, this connector is ideal for many applications where reliable and dependable connections are of the utmost importance.
