Rectangular Connectors - Headers, Male Pins

Rectangular connectors, also known as headers, are designed to connect two devices together. The most common type are those with male pins, which are also referred to as DIN connectors. DIN stands for Deutsche Industrie Norm, the German standard for connectors. The two devices that are to be connected are typically enclosed in an electronic assembly, such as a motherboard, a circuit board, or a cable assembly. In this application, the male pins make physical contact with the mating parts of the two devices.

The two main types of rectangular connectors are headers, which are with male pins, and receptacles, which are with female sockets. The main purpose of these connectors is to provide a reliable, secure connection between the two devices so that data or power can be passed between them without any disruption. This is why they are often used in electronic assemblies, such as in computers and cell phones.

The most common type of header are those with male and female pins. The male pins of the header are inserted into the female socket of the mating part, and then a latch mechanism is used to secure the pins in place. Depending on the type of connector, the latch mechanism can be either a latching mechanism or a snap-lock mechanism. Other common types of headers include those with hermaphroditic contact pins, which are either female or male, depending on the mating part, and those with disc-shaped contact pins, which are used for crimping and soldering.

The working principle of the header is based on the electrical conductivity of the male pins, which is ensured by the material used for the pins. These materials can vary and, depending on the application, may be aluminum, copper, bronze, brass, nickel-plated brass, or stainless steel. The material is usually chosen based on the expected resistance of the electrical connection. The contact pins are designed to remain in place securely, while allowing the required current or voltage to pass through them.

Most headers are designed to remain reliable when used in temperatures from -50°C to 130°C. However, due to the different materials and design elements employed in their construction, headers may also be designed to operate in temperatures that are even higher or lower. Some headers may be used in temperatures as high as 200°C or even more, depending on the type of application.

When it comes to installation, headers are usually secured with screws, nuts, and bolts, or other mounting hardware. Depending on the specific application, the mounting hardware may also be provided with the headers, or it may be purchased separately. Once the header is securely installed, the mating parts can then be connected to the header and the connection is complete.

Overall, rectangular connectors or headers are a versatile and reliable type of connection used in a wide variety of applications. From computers and cell phones to gaming consoles and automotive electronics, headers with male pins are essential tools for the efficient functioning of these electronic devices.
