Rectangular Connectors - Headers, Receptacles, Female Sockets 0872632034

Rectangular Connectors are a type of electrical connector typically used to connect systems or circuits to provide an electrical communication or to interconnect mechanical components. They come in a wide range of sizes and configurations from simple 2 to 8 pin interconnects to high-density, multi-cavity designs. They offer reliable connections and superior strain relief in extreme climates, repeated insertions and vibrations.

Types of Rectangular connectors

There are three types of rectangular connectors: Headers, Receptacles and Female Sockets.

Headers

Headers are solid, pre-wired connectors that typically have a modular housing, allowing them to be plugged into a larger mating part or device. They provide protection for the electrical contacts and are usually very easy to install. Headers often have a range of pin spacings and can be used for both through hole and surface mount designs.

Receptacles

Receptacles are also modular housing connectors that are designed to accept a plug-in connection. They are most commonly used when there is no space or need to provide access to the connected device. Receptacles are often designed to accept both male and female pins of varying sizes.

Female Sockets

Female sockets are the female counterpart of the male plug. They are used to provide an electrical connection between two or more components. Female sockets can be used with a variety of applications including board-to-board, cable-to-board, and card-handling.

Application Field and Working Principle

Rectangular Connectors are widely used in various industries such as automotive, telecommunications, data communications, consumer electronics, food and beverage. Their main application is to provide a reliable electrical connection between components, circuits, and systems.

The working principle of rectangular connectors is based on electrical contact. The pin terminals that are inserted inside the connector contact the corresponding internal sockets to form an electrical connection. This connection can either be a single contact point or multiple contact points if the connector has multiple pins. The reliability of this electrical connection depends on the contact force between the pins and the sockets, the geometry of the pins, and the electrical characteristics of the contact material.

The contact force between the pins and the sockets is often achieved by using crimps, clips, or other retention devices. The geometry of the pins also affects the connection, as the amount of surface area in contact between the pins and the sockets will determine the connection’s strength. Lastly, the electrical characteristics of the contacts can also play a role in determining the connection’s reliability.

In addition to their main function of providing an electrical connection, rectangular connectors can also be equipped with additional features such as strain relief, dust caps, and shields. These features are designed to protect the connectors from external damage and extend their life expectancy.

Rectangular connectors are reliable, cost-effective solutions to various applications. They offer a range of pin spacings, multiple contact points, and a variety of additional features that improve connection reliability and longevity.
