Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors are incredibly versatile, performing their duties in a number of different industries, including telecommunications, medical equipment, automotive, and more. Within the rectangular connectors family, there are three distinct types: headers, receptacles, and female sockets. Understanding their individual characteristics and application fields allows for optimized functionality and implementation.

Headers

Headers are an incredibly appropriate name for this type of connector, as they often appeared ‘header’ on circuit boards before the utilization of surface mount technology. This type of connector typically contains a wire wrap or through-hole design for connection purposes, depending on the specific application. 4-175638-6 headers have a dual side contact accommodating an insulation displacement orientation and are typically installed with a low cost compression tool. Suited for prototyping, pre-production, and production environments, the headers come in a variety of pin numbers and also support pre-loaded, ribbon, and flat cable terminations through a standard .100 plated through-hole.

Receptacles

Receptacles, also often referred to as female connectors, are designed to match the 4-175638-6 headers. Like the headers, their application can come in the form of insulation displacement, crimp, solder, or press-fit designs. They serve as the ‘mating piece’ of the connection, connecting the component to the panel or board. They come in low profile and right angle orientations, both of which are designed for secure latching, featuring a raised handle for a secure grip. Receptacles are typically triple-beam-contact type, giving them superior resistance to shock and vibration when compared to traditional connectors.

Female Sockets

Female Sockets, as their name implies, are female connectors with 4-175638-6 rectangular socket sections which are used to connect two conventional round pins. While round pins are used in a majority of electrical systems, there are times when a rectangular interface is needed or desired, leaving the user no choice but to employ a female socket. This type of connector is most often used to connect wires which are already in place with cablings, or for situations where traditional rectangular connections are unavailable. Examples of common female sockets include telephone adapters, USB connections, and even audio cables.

4-175638-6 Application Field and Working Principle

The 4-175638-6 connector is a well-known model of rectangular connector that\'s been around for decades. Primarily used for military and rugged industrial applications, their use has also come into play in comparative lower power consumer electronic products, such as PCs, where the higher current ratings of standard connectors, such as PCMCIA, USB, or even SCSI, are not required.The 4-175638-6 is constructed to take many of the key aspects of ruggedized connectors into account, such as increased resistance to high vibration and shock, high temperatures, corrosion, and also protection from EMI/RFI interference. Its distinctive feature comes in the form of a loop contact design, which allows for increased reliability and performance in extreme designs. This is accomplished by having multiple rows and multiple pins of contacts, confirming to the highest standard of MIL-DTL-83513. The contact terminal itself is typically composed of a spring-type contact, which is encased in an insulator by an encapsulated shell. This structure is then sealed, made up of a combination of bronze and stainless steel, making it resistant to extreme temperatures and excellent corrosion resistance.The principles of operation for this connector style are based on the idea of enhanced reliability and resistance to extreme conditions, while still maintaining competitive power ratings. The connector has the ability to support up to an 8 Amps current rating, which is suitable for many consumer electronics applications, as well as even certain applications in more rugged environments. The design also allows for more reliable connection to the socket than traditional models due to its loop contact design, which provides more contact surface area in addition to increased strength for a more robust connection.In conclusion, the 4-175638-6 rectangular connector family is a versatile and reliable choice for a variety of applications. From military and industrial applications to consumer electronics products, its loop contact design provides reliable, enhanced performance and power in extreme conditions. It features headers, receptacles, and female sockets, all of which are designed to provide secure connection, while still resisting shock and vibration in hostile environments.
