Rectangular Connectors - Headers, Receptacles, Female Sockets

71991-312 rectangular connectors are used most often for the transfer of electrical power or signal path connection between two or more components, systems, or subsystems. This type of connector is also known as a header, receptacle and female socket. The 71991-312 is typically used in applications such as telecom, automotive, radio and networking. They are designed to provide reliable, durable, and secure connections.

Design and Construction Features

The 71991-312 rectangular connectors are designed with an insulator-enclosed and 4-pole-and-male-and-receptacle contacts. The contact arrangements extend parallel to each other in series down an internal, conductive track. On the connector’s surface are metal pins and shells for improved contact security and electrical continuity. In addition, the insulator is also soldered to the backplane of the system circuit board in order to provide an additional layer of electrical shielding. This prevents unwanted signals from being transmitted from one system component to another within the same system.

The 71991-312 rectangular connectors also feature latching tabs for superior connector retention and securement. The latch is typically made of metal. The latching tabs are typically located at the sides or top of the connector body, providing a secure and reliable connection. O-rings may also be used for additional electrical protection.

Working Principle

The 71991-312 rectangular connectors follow a basic working principle by plugging into one another for a fast and secure electrical connection. When the two parts are connected, the male and female components interlock with each other to create a secure electrical connection. This provides a reliable and robust connection. The contact pins within the connector then perform their current-conducting function between the systems.

In addition, the 71991-312 rectangular connectors also feature strain relief grommets. The strain relief grommets provide additional protection for the connector from external forces, including tension, vibration, and pressure. They also reduce the amount of stress placed on the connector components, extending the life of the connector.

ApplicationsThe 71991-312 rectangular connectors are commonly used in many applications, such as telecom, automotive, radio and networking. In telecommunications, the 71991-312 is used for radio frequency (RF) transmission and reception, and for cable maintenance. In addition, they are also used in automotive applications such as ignition coils, diagnostic systems, and electrical power distribution for engine control modules.

In networking applications, such as local area networks (LANs) and Ethernet networks, the 71991-312 is used to provide an electrical pathway between two or more networked systems, such as PCs, routers, hubs, switches, etc. The 71991-312 is also used in radio applications for the transmission and reception of wireless communication signals and for antennae connections. Finally, the 71991-312 is used in conventional electrical power distribution for systems such as HVAC systems, lighting systems, and security systems.

Conclusion

The 71991-312 is a versatile and reliable electrical connector designed for use in various applications, such as telecom, automotive, radio, networking, and conventional power and signal applications. The 71991-312 features metal pins, shells, latching tabs, and strain relief grommets for improved electrical protection. Its working principle is simple to understand and its interlocking male and female components provide a secure connection.
