Rectangular connectors, also known as headers, male pins, and feed-through terminals, are electronic connectors that are used for building and maintaining electrical circuits. They are commonly used in electronics, motors, and data communication systems. These connectors are usually found in applications where high current or voltage needs to be transferred between two or more points in a circuit.

The most commonly used headers are rectangular connectors with round pins, and they are made from a variety of materials such as brass, stainless steel, and aluminum. The pins are usually attached to the connector either soldered or crimped. Rectangular connectors with male pins are the most popularly used type of header.

The basic components of a rectangular connector with male pins are a female housing section, which houses the female pins, and a male housing section with the male pins. The female pins are usually molded into the female housing section while the male pins are attached to the male housing section. The pins are typically inserted into a female receptacle to create a connection. The male pins of the connector can be either threaded or soldered into the female receptacle. Alternatively, the female housing section can have pins that are threaded or soldered into the male housing section of the connector.

It is important to note that, when selecting rectangular connectors with male pins for a given application, careful consideration should be given to the materials used for the connector, the number of pins in the connector, the size of the connector, the current carrying capacity of the connector, and the environmental conditions in which the connector must operate. Factors such as the voltage and current requirements and the operating temperature should be taken into account when choosing a connector to suit the needs of the application. If the conditions under which the connector will be operating are extreme, there may be a need to use a higher specification connector to ensure that it can withstand the conditions in which it will be used.

The working principle of a rectangular connector with male pins is simple. A metal contact is attached to each of the male pins. When the pins are inserted into the female receptacle, the contacts make contact with the pins in the female receptacle and close the connection between the two parts. The electric current is then allowed to flow from one end of the connector to the other. The current is regulated by the resistance of the metal contact inside the connector.

Rectangular connectors with male pins can be used in a variety of applications, from consumer electronics to military and aerospace systems. These connectors are often used for carrying current in high voltage electrical and electronic circuits. They are also used in applications such as battery packs, LED strips, and computer motherboards. This type of connector is also often used for connecting devices to each other, such as routers, systems, and other network components.

Overall, rectangular connectors with male pins are a useful and versatile type of connector. They offer flexibility in terms of the number of pins and the materials used for the connector, making them ideal for many applications. They also offer reliable and efficient connections, with low resistance and low voltage drop, making them an excellent choice for many electrical connections.
