Common types of electrical connectors electricity formulas grade 9

Electrical connectors are critical components in countless electronic devices because they both enable and protect the transmission of an electrical signal. From connecting key computer elements to joining wires in the cars we drive, the roles they play are vast and the applications they service diverse. Despite their simple design, connectors often perform in complex electrical systems. As a result, connectors must be durable and reliable while remaining easy to assemble and use. Though not all electrical connectors are designed to withstand use in extreme environments,the extensive array of connector specifications ensures that an appropriate variant can be found for a given device.

An 8P8C connector derives its name from the phrase “eight positions, eight conductors.” As the name implies, this small connector has eight possible positions, each with a corresponding conductor. It is a kind of modular connector that was originally used in telephone wire applications, but can serve a variety of other functions as well, such as use in Ethernet jacks. All four sizes of modular connectors are named according to the number of positions and conductors they possess, including sizes 4,-, 6-, 8-, and 10-. A 10P8C, for example, would feature ten positions and eight conductors.

The 8P8C connector itself consists of a plug and socket connection, with a male plug and a corresponding female socket. The plug carries eight contacts that align with the socket’s eight conductors to transmit electricity through the connector. In addition to their use in Ethernet jacks, 8P8C connectors are also commonly found in computer applications and communication cables.

Much like the 8P8C connector, D-subminiature connectors are commonly used in computer applications, but in a different capacity: they function as a critical port (RS232) on modems. Despite the term “subminiature,” D-subminiature connectors are now relatively large in comparison to other, more modern computer connectors. Along with a D-shaped metal component, which protects the connector and defines its shape, a D-subminiature connector consists of two or more rows of varying numbers of pins (or sockets, depending on the gender of the connector). If pins are present, the connector is male and called a plug; the corresponding receiving device is called a socket, which houses the contacts to which the pins must connect in order to transmit electricity. Capabilities associated with this variant include the ability to protect against electromagnetic interference.

Direct Current (DC) connectors provide a given application with direct current, so they must be used carefully to ensure equipment isn’t damaged. Common types of DC connectors include DC plugs and coaxial DC power connectors, which primarily connect a device to a power source.

Universal Serial Bus connectors are small interface devices that can be used to attach over 127 devices to a computer. Standard laptops generally feature at least two USB ports to support external connection via USB connectors, while standard desktop computers feature four USB ports. Because a USB connector can be plugged in and unplugged while the connected device is on, it has widespread use in computer systems that continually require attachment and separation from external devices, as is necessary when transporting data.

As with many connectors, there are multiple USB variants. USB connectors 1.0, 2.0, and 3.0 are available for both high-speed and low-speed connections, with USB 1.0 models providing connections for keyboards and mice, and USB 2.0 offering connection to the same devices but at higher speed.
