Introduction

Rectangular Connectors, also known as Headers, Male Pins or Connectors, provide mechanical and electrical connections between two surfaces, often in the form of plug and socket connections. Generally, Headers are made up of two parts: the socket and the pin which are connected together using screws or rivets. In most cases, the socket end of the connection is the female part while the pin is the male part. The socket is typically a metallic base that is designed to easily allow the mounting of the pin. The pin consists of two electrically and mechanically interconnected components - the contact and the shroud which is placed around the contact. The shroud helps protect the other parts of the connector from physical damage, moisture and electromagnetic interference.

Definition and History

Rectangular Connectors, or Headers, Male Pins and Connectors, were first developed in the 1950s as a means of providing a sturdy electrical connection. They were initially used in military applications, primarily for aviation and aerospace uses, but have since been developed for a range of industries and applications. Originally, rectangular connectors were primarily used for applications that required power, such as motors, lighting, and other instruments.

Types of Connectors

There are several types of rectangular connectors, and the design and size of the connector will depend on its intended application. Some of the most common types of rectangular connectors are as follows:

• Pin & Socket Connectors - Pin & socket connectors have two parts: the pin and the socket. They are a type of mechanical connection that is primarily used to make electrical connections due to their durability and high number of contacts. Pin & socket connectors come in different sizes and are typically waterproof. 
• Locking Connectors - Locking connectors are typically used for power applications. They have two parts: the lock and the female connector. They are typically made of brass or steel and are designed so that when the two parts are inserted together, they are locked and cannot be disconnected. Typically, locking connectors are waterproof and resistant to corrosion.
• Circular Connectors - Circular connectors are a type of connector that is most commonly used for data and signal transmission. They are round in shape and typically feature two or more contacts. Circular connectors are designed to provide a reliable connection, and they are often waterproof and resistant to vibration and electromagnetic interference.
• High Voltage Connectors - High voltage connectors are designed to transmit high voltage power. They are typically used in industrial and commercial applications, such as factories and power plants. High voltage connectors are typically made of brass or steel and feature multiple contacts and locking mechanisms to ensure a reliable connection.

Application Field and Working Principle

Rectangular connectors, also known as Headers, Male Pins and Connectors, are used in a wide variety of applications, such as automotive, industrial, commercial, and home applications. For automotive applications, they are mainly used for connecting wiring to the vehicle’s electrical system. In industrial and commercial applications, they are mainly used for transferring power from one component to another. In home applications, they are typically used for connecting electrical outlets, lighting, and appliances. The working principle of rectangular connectors is fairly simple. When a pin is inserted into the socket, the contact points inside the connector form an electrical connection. This connection allows current to flow from the pin to the socket and back again. In order for the contact points inside the connector to form a reliable connection, the pin and socket should be sized correctly and aligned properly.

Conclusion

Rectangular Connectors, also known as Headers, Male Pins and Connectors, are an important component in a wide variety of applications. They provide reliable and durable electrical connections that are resistant to moisture and other environmental factors. The different types of connectors available are designed for specific applications, which makes it important to have the right type of connector for the intended application.
