71991-340

Rectangular connectors are a versatile type of electrical connector used in a wide range of industries and applications. The 71991-340 connector is a header or receptacle type rectangular connector that is widely used in the automotive, industrial, medical, and military sectors due to its robust design and reliable performance. The design and working principle of this connector are described in detail in this article.

Connector Design

The 71991-340 connector is a standard female socket type connector with two tabs that insert into the mating component. The connector has four contact points, which are placed in two rows with two contacts in each row. The contacts and crimp barrels are made of copper and are gold-plated for optimal performance. The shielding of the connector is also made of copper, with a black plastic hood. The connector is insulated and rated for 300V.

Working Principle

The 71991-340 connector uses a three-dimensional mated configuration to create an electrically insulated connection. To do this, the contact pins are inserted into the mating component, and the two tabs are crimped around the contact pins. This ensures a secure connection between the two mating components. Additionally, the shield is secured onto the board to further protect the connection from any outside interference. Once assembled, the 71991-340 connector guarantees a leak-proof connection.

Applications

The 71991-340 connector is used in a wide range of applications. In the automotive industry, it is used to connect electrical components, such as sensors, switches, and wires. In the industrial sector, it is commonly used for power and data transmission between machines and other systems. In the medical field, the 71991-340 is used to connect medical devices such as monitors, pacemakers, and heart rate monitors. Finally, in the military sector, this connector is used to connect radio and satellite systems.

Conclusion

The 71991-340 connector is a robust, reliable, and versatile female socket type connector that is widely used in various industries and applications. It uses a three-dimensional mated connection to create an electrically insulated connection, and its special shielding ensures minimal interference from outside sources. The 71991-340 connector is an invaluable tool in the automotive, industrial, medical, and military sectors, and is sure to be an important part of many future projects.
