Rectangular Connectors: Headers, Male Pins

Rectangular connectors are the type of electrical components used to connect two separate circuits or conductors, allowing power and signals to move between them. The rectangular connectors feature two wires or pins that are typically surrounded by plastic insulation and are arranged in a rectangular frame in a predetermined pattern. Headers and male pins are two of the most common rectangular connectors.

Headers

Headers, also known as male pins, are usually found in electronic devices, such as cell phones, computers, or televisions. The type of header used in these devices may vary depending on its application, but it is typically a two-wire connector when used with other electronic components.The most common use for headers is for connecting two resistors, capacitors, or other types of electronic components together. The two wires or pins that protrude from the header are often used to bridge the gap between the two electronic components and provide a secure, conductive connection.Headers are typically designed with a single contact strip on one side and two solder tabs on the other side. As the solder joints allow the components to be connected without the need for a mechanical connection, they offer higher reliability and convenience when compared to older mechanical and hand soldered connections.

Male Pins

Male pins are relatively similar to headers, but have one minor difference—they are typically used for the connection of a single component, instead of two. The pins are usually found in male connectors and plugs, but they may also be used for connecting standalone components such as a capacitor or resistor.Unlike the header, male pins are designed with a single contact point and do not require any additional components for completing a connection. This makes them an ideal choice for tight spaces or when a mechanical connection is not necessary.

4-102978-0-11 Application Field and Working Principle

The 4-102978-0-11 is a type of male pin header that is commonly used in various electronic appliances and devices, including cell phones, computers, and televisions. The most recognizable aspect of the 4-102978-0-11 is its distinct shape, which is made to allow the contacts to be securely inserted without the use of any tools.The working principle of the 4-102978-0-11 is relatively simple- one end of the connector is placed into the desired connection, and the other end is slightly inserted into the connection, forming a complete electrical circuit. In order to complete a connection between two components, the pins are simply pushed into the corresponding holes so they securely touch the components without creating any physical connections. This allows for a fast, reliable connection and prevents any shorting or arcing that can occur with traditional hand soldered solutions.The applications of the 4-102978-0-11 also include connecting two or more components within an electrical circuit, such as resistors, capacitors, or inductors. Additionally, the 4-102978-0-11 can also be used to connect multiple cables or wires that are transferring current or signal. The contact points of the connector act as conductive joints to combine two separate conductors into a single, secure connection.The 4-102978-0-11 benefits from its small size, which allows it to fit into tight, space-limited areas. It is also versatile, as it can be used in a wide range of applications, from simple electronic circuits to automotive wiring systems. The sturdy design and durable construction mean that the 4-102978-0-11 can withstand the abuse of multiple insertions and contact with high currents, making it a reliable option for connecting circuits.In conclusion, the 4-102978-0-11 is a highly versatile, compact, and reliable connector that can be used in a variety of electrical applications. The robust design and contact points make it resistant to wear, tear, and high levels of current, providing a secure and reliable connection for many electronic components.
