Rectangular Connectors - Headers, Receptacles, Female Sockets
Rectangular connectors are the most commonly used connection devices for a variety of electronic components and equipment. These devices are made up of two pieces, a male and female connection that interconnects with the use of a connector, like the 350991-4.

The 350991-4 is a 4 pin female rectangular connector used for rectangular power connectors. This type of connector is composed of two metal contacts connected in a “V” shape with claw contact tensioners, usually made of steel. The tensioners secure the male contact in place. The exterior of the 350991-4 is typically formed with thermoplastic polyester, providing protection from external influences and a tight fit with its corresponding male connector. Generally, the securing means is a pair of square bolts with hand-operated knobs which bring the contacts together tightly. The interior of the casing is usually plated with tin for an improved electrical conductivity and increased corrosion resistance.

The main application of the 350991-4 connectors is in the industrial and consumer fields. It is used in power supplies, backplane interconnects, computer cables and power cables used in commercial and industrial technology. It is also commonly used in air conditioning systems, electrical contactor, thermal actuator, and in applications such as phone systems, medical equipment, aviation equipment, and automotive control systems. The wide application of these connectors stems from its excellent electrical properties of high voltage, excellent humidity resistance and strong mechanical structure.

The 350991-4 connector design has changed over the years. It is now much easier and simpler to use than its predecessors, with improved features such as increased resistance to shocks and vibration, improved retention force, and easier fitting. Additionally, the 350991-4 has a high degree of electrical and mechanical reliability with extreme temperatures and sealing. The new designs also take into consideration customer convenience, environmental sustainability and optimization of materials used.

The working principle behind the 350991-4 is simple and straightforward. When the male and female connectors are placed together, the steel claws on the female connector pierce the male contact and the hand-operated knobs are turned to tighten the fit. This creates an electrical connection, allowing power to pass through the connector. The connector also features a locking mechanism that ensures tight fitting and easy dismounting. This ensures that the connection is secure even when used in the presence of extremely high static electricity levels and vibration. Additionally, the design ensures that no damage occurs to the pins or the contacts when the connectors are joined, thus ensuring a good electrical connection.

The 350991-4 connector has been used in a variety of applications and continues to be embraced by industries worldwide for its exceptional properties. It is a reliable and easy to use connection device for many applications. With its easy fitting, reliable operation and long-term performance, it is an ideal choice for a wide range of applications.
