831-41-018-20-001000 Rectangular Connectors - Headers, Receptacles and Female Sockets - Application Field and Working PrincipleRectangular connectors (also known as headers and receptacles, and also commonly known as female sockets) are electrical connectors used in a variety of applications such as power, signal, data, and communication. Their main function is to connect electrical circuits, enabling data transmission between systems.Rectangular connectors generally consist of a housing, a connector body, contacts, and mounting hardware. The housing is the outer covering of the connector, and holds the connector body, which is the core of the connector. Contacts provide mechanical support and provide electrical connections between the two systems, while the mounting hardware facilitates the arrangement of the contacts within the housing.The application field of rectangular connectors has been expanding in recent years due to their robustness and versatility. They can be used for a variety of purposes: to provide power, data, and signal lines between boards, systems, and other components; and for building wiring and bus systems. In addition, they are ideal for use in harsh environments such as outdoor and industrial applications, where their durability is highly sought after.The working principle of rectangular connectors is quite simple. The connector body consists of two thermoplastic halves. These two halves are held together by two small screws that run through the connector body. When the two halves are fitted together, they form a compact unit. This arrangement allows contacts to make contact with one another when the contact points are brought into contact.When an electrical current is applied, a tiny voltage drop occurs between the contact points, which in turn triggers a reaction in the contact spring. This reaction forces the spring to move and the contact to open, which in turn causes another reaction in the contact\'s material. Subsequently, this material will vibrate at a rapid velocity and cause a magnetic field to be generated. This magnetic field will cause electrons to jump from one contact to another, resulting in electrical transmission.In sum, rectangular connectors are an essential component for a wide array of applications and offer the robustness and versatility necessary to simplify and improve the performance of electrical work. The application field of rectangular connectors has been rapidly growing, and their working principle is easy to understand and use.
