Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors have become increasingly popular over the years for the use in a wide variety of applications. This type of connector is not limited to the traditional electronic field but is gaining in popularity in the medical, automotive, aerospace, communications, and industrial fields.The primary connecting elements in the rectangular connector group are headers, receptacles, and female sockets. Headers are the male connectors, receptacles are the female connectors, and female sockets are female receptacles. The defining characteristics of these three types of connectors are their physical dimensions, the type of termination, and the contact design. A variety of materials are used to manufacture rectangular connectors with the most common being metals such as copper alloys, nickel or stainless steel. Plastic variants are also available though their usage is more limited.The primary physical characteristic of the rectangular connector is the rectangular features giving it a box-like shape. Depending on the application, the header or plug can have somewhere between two to 128 contacts. The contacts are typically maintained in either two, three, or five rows. The contact pin arrangement depends on the number of contacts and in some cases can be different depending on the direction of the connectors insertion.The type of termination is an important factor in the design of a rectangular connector. Generally, the choices fall between cut cable, type crimp, and quick connect with different designs favoring one or the other. The type of termination will determine the mating method of each of the connectors.The contact design can range from board mount to inline depending on the application. In some cases the contact design for the header is different from that of the receptacle or female socket. This is done to ensure that the contacts are maintained in the proper position when the two mating connectors are connected.The working principle of a rectangular connector is based on the spring pressure of the contact pin pushing against the mating connector and creating a connection. The conductive contact is established and a data transfer or a current flow is established. The main purpose of the connector is to ensure the electrical connection is maintained through the varying conditions such as vibration, shock, and environmental contamination.Rectangular connectors have become an integral part of modern day electronics. From mobile phones to medical equipment the reliability of the connection provided by the rectangular connector is key to ensuring the system performs as expected over the life span of its use. The wide range of designs available and increasing popularity will ensure the connectors keep their place in the electronic world for years to come.
