Rectangular Connectors - Headers, Receptacles, Female Sockets

The 350641-1 is a rectangular connector commonly found in military and aerospace applications. It is a ruggedized, environmental resistant package with a built in locking feature designed to secure connections in harsh, extreme conditions.

The connector is a standard four post pin and socket type terminal, allowing for sealed connections that are able to handle high power loads in fixed locations. While the body is manufactured from a variety of materials, typically thermoplastics and metals, depending on the applications, the pins and sockets are generally stainless steel. The design is very versatile, with the ability to configure and field customize connections onsite with the use of gender changers.

The 350641-1 fits within the rectangular connector category that are widely used due to their modular, light ‘board for board’ designs. They are built to connect compact printed circuit boards to other boards, backplanes or even cubes. Essentially, the connecting parts slide onto corresponding header supports on either side of the application, allowing the device to be securely connected without having to solder or use any other tools.

The construction of the 350641-1 extends beyond connection points, as they come in a variety of options to control mating, power, and other aspects of the connection. This includes the use of standard “End Stops” with one or zero or more posts than the other side and “Ramps” for dual sided configurations, which feature quick-release features. Furthermore, both ground and power pins can be omitted from the pin pattern of a connector to reduce size and weight.

Application Field

The 350641-1 is one of the most reliable and popularly used connectors for applications where reliable and dustproof connections must be achieved between adjacent boards. It is especially suitable for applications requiring data, signal, and power transfer within a limited space such as in chassis and rack mount equipment. It can be used to connect peripheral and computing devices, communication and power devices, as well as environmental control systems.

The 350641-1 is built to resist vibration, shock and humidity, and features a sleek profile, satisfying both safety and cosmetic requirements. This makes it suitable for a wide variety of military and aerospace applications, such as drones and satellites.

Working Principle

The 350641-1 is a sealed, four post pin and socket type connector capable of transferring over 180V at 10A current. The connector fits together using two header support posts, usually on the edge of a PCB, with pins and sockets as primary components. Assembling the connector is accomplished by using the pins to press fit into the sockets located on both the male and female halves of the connector.

The connector has a special, locking feature to ensure mechanical and electrical performance as well as preventing accidental disconnection or damage in extreme temperature and vibration environments. The locking feature is engaged by pressing both header supports against each other with a left and right hand turn and then locking them with a simple twist and release system.

Once assembled, the devices offer a robust connection protected from chemicals, dust, vibration, and thermal cycling. The power and data transfer capabilities of the device are further improved by using a dielectric filler, which prevents any electric current or voltage leakage.

The 350641-1 is a very reliable connection method, and useful in many different applications. Its sturdy design, locking feature, and versatile design make it an ideal connector for use in harsh, extreme environments.
