Rectangular connectors refer broadly to any electrical or electronic connector characterized by rectilinear shapes utilized for data, communications and power applications. The most common types of rectangular connectors are headers, receptacles, and female sockets, all of which are discussed in this article.

0015445864 Application Field and Working Principle

1. Headers
Headers are typically composed of two different parts - terminals and housings. The terminal pins are attached to the housings, and the housings are made of a dielectric material that maintains the spacing between the terminal pins. Headers can be either printed circuit board (PCB) mountable or socket mountable and available in various number of contacts.

The most common types of headers are single, shrouded single and dual. Single headers are composed of an array of pins that can either be right-angled or have straight ends. Shrouded single headers have metal shrouds that surround the pins when plugged in and provide better protection against EMI/RFI. Dual headers are a combination of single and shrouded single headers and consist of two rows of pins in the same housing.

Headers are mainly used to connect printed circuit boards and electrical components. They are usually connected by soldering or crimping, depending on the materials used. They are used in a wide range of electronic products, from laptops and printers to industrial machinery and automobiles.

2. Receptacles
Receptacles are devices that are used to mechanically and electrically connect a male-shaped connector called “pins” to older devices. Receptacles typically consist of two parts, the shell and the contacts, which are wrapped in plastic insulation. The shell is the part that physically holds the contacts together inside the receptacle, while the contacts are the metal pieces that contact the pins of the connectors.

Receptacles are available in a variety of different configurations and sizes and can be used in almost any electronic application. They are available in both surface mount and through-hole versions and can be used as on/off switches and LED drivers. They are most commonly used in automotive and consumer electronics systems.

3. Female Sockets
Female sockets are connectors that are used in order to connect male terminals. They are usually composed of two parts, the plastic housing and the contact pins, which are held together in the housing. Female sockets come in a variety of shapes and sizes and are available in both single-ended and double-ended configurations.

Female sockets are typically used in applications that require an electrical connection and can be used to connect a wide variety of devices, from simple cables and sensors to more complex systems such as computer motherboards. They are also commonly used in automotive and industrial control systems where a strong connection is required.

These are just some of the common types of rectangular connectors. All of these connectors have their own unique applications and can be used in virtually any electronic system. While the types and applications discussed in this article are the most common, there are many more types and configurations available on the market.
