Rectangular Connectors, as the name implies, are two-dimensional plug-and-play components. They are typically mounted on a PCB or printed circuit board and are used in many electronic equipment and system applications. Connectors can be categorized in two classes: Headers and Male Pins. In terms of their application and working principle, both of these classes have similarities.

Headers

Headers are preferably used in PCBs and are used to connect two circuits. In a typical application, one or more headers are placed on a printed circuit board and then pushed into holes that have been drilled along the board\'s edges. This allows a circuit to be connected in a quick, efficient manner. Headers are available in two main styles, "board-to-board" and "edge-card." With the board-to-board style, two PCBs are mated together using pins and headers to form an integrated circuit. The edge-card style, on the other hand, consists of a header assembly, which combines a male and female connector, and which can be used to provide an individual connection between two components.

Male Pins

Male pins are used in a variety of applications, including the connection of wires, cables, or printed circuit boards. They are typically made of metal, and have a male connector on one end and a female connector on the other end. The female connector is used to make a connection by inserting it into a female connector mounted on another device, such as a board or cable. Male pins are typically used to provide a secure, reliable connection between two components, and can also be used to reduce the risk of accidental disconnections.

Applications

Rectangular Connectors are used in many different applications, including automotive, medical devices, industrial controls, computer systems, consumer electronics, telecommunications, and more. These connectors are used in a wide range of electronic systems and equipment, from cars and medical devices, to industrial robots and computers. In many cases, the connectors are used to connect the various parts of an electrical system, such as power supplies, peripheral devices, and more.

Working Principle

The working principle of connectors is fairly straightforward. A pin is inserted into the female connector of the component to be connected. The male pins of the connector then slide into the holes of the connector and create a secure connection. Connectors can be single-ended or double-ended. Single-ended connectors have one end that is connected to a single wire, while double-ended connectors are used to connect two wires.

In addition to providing a reliable, secure connection, connectors also provide a means for attaching additional components to a circuit board. This is done by connecting a male pin to a circuit board, and then connecting a female pin to the component to be connected. This allows for easy removal and installation of components without the need for soldering or other mechanical procedures.

Overall, Rectangular Connectors provide a convenient, reliable way to connect electronic components. Headers and male pins are both used to achieve this, and they each have their own distinct advantages and disadvantages.
