![]() ![]() ![]() Most computers and laptops come equipped with several USB ports. Compatible with multiple platforms and operating systems these connectors are an ideal choice for most consumer electronics. CharacteristicsĪ USB connector is intended as a temporary connection and therefore has flat, durable contacts that can withstand repeated attachment and detachment. It aided in standardizing these connections and eliminated the need for separate power chargers for every individual portable device. USB connectors came about in the 1990s with the rise of computers and peripheral devices to make connecting these devices easier. In addition, they’re widely used in aircraft electrical systems. You’ll find D-Subs used in RS-232 serial communications, network ports, computer video output, and game controller ports. The installation screws make for a semi-permanent, but reliable connection. Low density d-subs have two rows of pins or sockets while high density d-subs have three. Their D-shaped metal shield provides mechanical support, ensures correct orientation and can possibly screen against electromagnetic interference. While they’re no longer prevalent in consumer electronics, they’re still widely used in commercial equipment. Nowadays, they’re large, cumbersome, and almost obsolete. At one point, D-Subs ranked among the smallest connectors used in computer systems. The invention of D-Subs allowed for a means of connecting early computer models to monitors, printers, and floppy disc drives. In later installments, we’ll take a much more detailed view at a couple of the most popular electrical connectors in the industry. In this general overview we’ll cover the most common types which include: D subminiature, USB, RF, and power connectors. Each has its varying characteristics and specific purpose. Many kinds of connectors exist with multiple variations. If you’ve traveled out of the country before you’ve probably had to purchase a power adapter which lets you plug in multiple types of power connectors to a wall socket. Adapters are available to connect two different types of connectors together. Depending on the circumstances the connection can be either permanent, semi-permanent, or temporary.Ī connector consists of a plug (male connectors) or jacks (female connectors). They either connect electronic equipment to one another or they power sources. Electrical connectors join two electrical circuit paths together. The type of connector used ultimately depends on the type of connection needed. When it comes to cable assemblies, deciding what type of electrical connector to install is the first decision you need to make. Authorized System Integrator for Fanuc America, Inc.
