151467 Connectors, Interconnects

Rectangular connectors, also called rectangular cable connectors, are highly versatile types of terminals that are designed to fit a variety of needs. Their application fields, working principles, and uses vary depending on the type of connector being utilized. This article will discuss the most commonly used rectangular connectors, their application fields and working principles.

D-Subminiature Connectors

D-Subminiature connectors, also known as D-Subs, are one of the most widely used electrical wiring solutions and were first introduced in the 1950s. They are used in a wide range of electronic devices, from computers to telecommunications equipment. The D-Subminiature connectors have a metal shell with pins and sockets that hold various types of wires. The pins, also known as male connectors, are often found on cables, while the female sockets are typically found on devices such as computers. The pins and sockets are available in different sizes and designs, making the D-Subminiature connectors suitable for a wide array of applications.

D-Subminiature connectors work on a simple principle, where metal pins are inserted into slots in plastic sleeves, and then connected together with the pins attaching to the slots. The connection is then secured by fastening screws or clips. This connection is insulated from the environment and is designed to transmit both electrical and electronic signals. The pins used for the connection can be pre-wired or soldered, depending on the requirements of the application. D-Subminiature connectors are typically used for communication and data transfer, as well as in audio/visual applications.

Miniature Connectors

Miniature connectors, also known as mini-connectors, are much smaller than their D-Subminiature counterparts. They are most commonly used in miniature electronic components and can be found in a wide range of applications, including medical, aerospace, and industrial applications. Miniature connectors are available in various sizes, with pins ranging from as small as 1mm in diameter. Miniature connectors are designed to accommodate a broad range of miniature wires and cables and come in different pin and socket configurations.

Miniature connectors work similarly to D-Subminiature connectors, where metal pins are connected to the plastic sleeves found inside the connector. However, miniature connectors are much smaller than D-Subminiature connectors and the pins used can be much narrower. Miniature connectors can be either pre-wired or soldered, depending on the application. Miniature connectors are often used for signal and data transmission and are highly reliable.

Rectangular Printed Circuit Board (PCB) Connectors

Rectangular printed circuit board (PCB) connectors are a type of electrical connector that is used to join electrical circuits in electronic hardware applications. PCB connectors are available in a variety of sizes and shapes, with the most common being rectangular in shape. These connectors are designed to securely fit on PCBs and can be used to connect a variety of components, such as chips, resistors, and transistors.

PCB connectors work by connecting pins on the board to slots in the connector. The pins must be securely inserted into the slots and are typically fastened with either screws or clips. The pins used in PCB connectors can be either male or female, depending on the application. The pins are typically made of either copper or brass, depending on the type of application. PCB connectors are primarily used in electric circuit designs and can be found in a variety of consumer electronics.

Rectangular Coaxial Connectors

Rectangular coaxial connectors are specialized types of electrical connectors that are designed to provide an electromagnetic connection between two components. These connectors are primarily used to connect coaxial cables, which are cables that contain one or more inner conductors surrounded by an electrical shield. The rectangular coaxial connectors are designed with a metal shell that houses pins to which the cables are connected.

Rectangular coaxial connectors work based on the principle of providing a reliable electromagnetic connection between two points. The pins on the connectors are inserted into the slots in the cables and are typically secured with screws or clips. The electrical connection is secured by means of an electrical seal, which prevents current or signals from escaping. Rectangular coaxial connectors are most commonly used in applications that require the transmission of signals over long distances, such as for telecommunications.

Conclusion

To summarize, rectangular connectors are highly versatile types of terminals that are suitable for a wide range of applications. The most common types of rectangular connectors are D-Subminiature connectors, miniature connectors, rectangular printed circuit board connectors, and rectangular coaxial connectors. Each type of connector has its own working principle, and can be used in various types of applications. Rectangular connectors are reliable, easy to use, and durable, making them a great choice for all types of electrical and electronic applications.
