Rectangular Connectors - Headers, Male Pins

Rectangular connectors are an important type of electrical connector that have many purposes in a variety of fields. They are commonly used in home electronics, automotive, medical, and industrial applications. Rectangular connectors come in many shapes and sizes, from basic two pin connectors to 8-way versions.

One of the most common types of rectangular connector used in various applications is the header, also known as a male pin. Headers are defined by their flat and elongated shape, which is designed to fit into a mating female connector. Headers are available with a variety of male pin sizes, from tight fitting 0.65mm and 0.8mm pins, to 1.50mm, 2.50mm, 3.50mm and 5.00mm versions.

Headers are designed to provide secure electrical connections that resist corrosion and wear over time. Different versions of headers have different electrical characteristics, depending on the level of current they can handle. The current rating of the header is generally indicated on its packaging. For instance, a 1.50mm header generally can withstand 10 amps of current, making it suitable for a variety of applications, whereas a 5.00mm header can withstand up to 30 amps of current.

When selecting a connector, it is important to make sure it is compatible with the application in terms of voltage, amperage, and polarity. Headers typically come in a straight horizontal orientation but can also be purchased in vertical and right angle configurations. Headers are sold with protective covers, which are made from materials such as thermoplastic or metal, and can be used to protect the pins from accidental contact and corrosion. Headers are typically sold in various sizes, ranging from 4 to 40 pins.

In terms of application field, headers are commonly used in many industries for a variety of purposes. In the computer sector, they are used to connect components to peripherals, such as printers, keyboards, and external hard drives. In the automotive industry, headers are often used to join different electric components such as spark plugs, oxygen sensors, and injectors. Similarly, headers are also used in consumer electronics, such as DVD players, televisions, and gaming consoles, to make connections between circuit boards.

The working principle behind headers is fairly simple and involves the use of an internal spring mechanism. When a mating female connector is inserted into the header, the internal spring mechanism compresses, allowing the female pins to make contact with the header\'s male pins. This creates a secure electrical connection in which electricity can flow between the two components. The internal spring mechanism ensures that the connection is maintained even under stress, such as movement, vibration, and temperature change.

In conclusion, rectangular connectors, such as headers, are an important type of electrical connector used in many different applications. They come in a variety of shapes and sizes, from two pin to 8-way versions. Headers are defined by their flat and elongated shape, which allows them to easily fit into a mating female connector. The working principle of headers involves the use of an internal spring mechanism that allows for a secure and reliable connection. Headers are suitable for many different applications, from automotive to consumer electronics, medical, and industrial.
