Rectangular Connectors - Housings

Rectangular connectors, also known as Housings, are electrical connectors designed to provide an electrical connection between two or more electrical devices. This type of connector is widely used in various applications, including communication systems, instrumentation, and medical equipment. Rectangular connectors, also known as Housings, are available in a variety of shapes and sizes, from miniature plug-and-socket connectors to large multi-pin connectors.

0019091129 Application Field and Working Principle

Rectangular connectors are commonly used in various industries, such as electronics, automotive, telecommunications, aerospace, and industrial automation. These types of connectors provide durable connections and secure electrical contact between wired components. The most commonly used type of rectangular connector is characterized by its two-piece design, with a plug housing and a socket housing. The plug housing is typically machined from plastic and contains a male contact resulting in a male plug. The socket housing, also made of plastic, contains a female contact, resulting in a female socket.

The plug and socket housings contain metal contacts, typically made of brass, that provide an electrical connection when mating with each other. These contacts are arranged in various ways, depending on the type of rectangular connector. The most common configurations are pin and socket, pin and blade, and blade and socket. Pin and socket contacts consist of a male pin contact housed in the plug and a female socket contact located in the socket housing. The configuration allows for a secure connection and an electrical connection is established when the pin is inserted into the socket. Pin and blade contacts male contacts in the plug housing, which mate with female blades housed in the socket housing.

Blade and socket contacts consist of a female socket contact housed in the plug housing and male blade contacts located in the socket housing. The configuration creates an electrical connection when the blade contacts are inserted into the socket contacts. All of these configurations require appropriate force to provide a secure connection, and many rectangular connectors come with a latch that locks the connection when engaged.

Most rectangular connectors are also rated in terms of current, voltage, and temperature. The maximum current and voltage ratings for the connector are listed in the device datasheet and should be checked to ensure that the connector can handle the current and voltage requirements of the application. The temperature rating for the connector also needs to be taken into consideration, as extreme temperatures can affect the performance of the connector.

In addition to the different contact configurations, rectangular connectors are also available with various options, such as shrouded or semi-shrouded plugs and keyed mating components. These options provide increased security and are used when an additional level of protection against accidental disconnects is required.

Rectangular connectors provide a reliable connection between components and are ideal for use in a variety of applications. They are typically rated for both current and voltage, which allows for use in high-power applications. In addition, the various contact configurations enable a secure connection when mated with the appropriate components. The various options, such as shrouded plugs, provide additional protection against accidental disconnects, making them suitable for applications that require a secure connection.
