Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors, also known as headers, receptacles, female sockets, and PCB connectors are commonly used in the construction of printed circuit boards, providing a connection for board to board, board to wire, board to component, and wire to wire. The 91601-412LF is an example of a rectangular connector which is a two piece connector which can be used for both signal and power applications. This article will discuss application fields and working principles related to the 91601-412LF.

Applications of 91601-412LF

The 91601-412LF connectors are designed for high density applications such as automotive, instrumentation, telecommunications, and consumer electronics. They are typically used in applications which require low profile and high current applications. The connectors are used in applications such as automotive body control, fuel injection, audio systems, instrument panels, building control systems, HVAC, and consumer electronics. They are also used in applications with high power and voltage requirements such as AC adaptors, power supplies, lighting electronics, battery chargers, and instrumentation.

These connectors are also used in applications requiring PCB-to-component connections. These include laptop computers, cell phones, GPS systems, automotive control units, programmable logic controllers (PLCs) and camera systems. Other applications of the 91601-412LF include LED lighting, motor control systems, battery chargers, and power supplies.

Working Principle of 91601-412LF

The 91601-412LF connector has two parts: a header and a receptacle. The header is made from a high-precision metal stamping that is machined to ensure precise hole placement and a specific overall size, while a stab-in type receptacle is inserted into the header contact. The 2 positions side clips on the header secure the position of the receptacle. The signal contacts in the receptacle are machined in precision, guaranteeing an exact fit with the proper mating pressure. There are three different types of receptacles available: a friction lock type, a thermal lock type, and a screw type.

The header and the receptacle each have a unique set of features that, when mated together, provide a secure electrical connection. The header contact is designed to guarantee contact reliability and the thermal lock type receptacle comes with special connections that ensure contact resistance for reliable operation in high-temperature environments. The friction lock type receptacle has a vibration proof design that ensures secure contacts in dynamic environments. This type of connector also has superior retention force compared to other connections.

To ensure a secure connection, the 91601-412LF uses the crimp-ring connection. This connection has a built-in shield that blocks external electromagnetic interference from affecting the transmission signal. The use of the crimp-ring connection provides reliable transmission between the board and cable.

Conclusion

The 91601-412LF is an example of a two-piece rectangular connector which can be used in applications which require high current and low profile. Common applications of the 91601-412LF include automotive body control, instrument panels, HVAC systems, audio systems, AC adaptors, power supplies, lighting electronics, and consumer electronics. The connector has two parts: a header and a receptacle. The header contact is machined in precision while the receptacle has three different types of connections to ensure secure connection. The use of the crimp-ring connection provides reliable transmission between the board and cable and blocks external electromagnetic interference from affecting the transmission signal.
