The connector mounted on the host or device is called the receptacle, and the connector attached to the cable is called the plug. The connectors the USB committee specifies support a number of USB's underlying goals, and reflect lessons learned from the many connectors the computer industry has used. Modes are identified by their names and icons, and the specification suggests that plugs and receptacles be color-coded (SuperSpeed is identified by blue).Ĭonnector properties USB extension cable, plug on the left, receptacle (nonstandard, receptacles normally not allowed on cables) on the right USB devices have some choice of implemented modes, and USB version is not a reliable statement of implemented modes. The modes have differing hardware and cabling requirements.
#Terminal connector types full
There are five speeds for USB data transfer: Low Speed, Full Speed, High Speed (from version 2.0 of the specification), SuperSpeed (from version 3.0), and SuperSpeed+ (from version 3.1).
#Terminal connector types portable
The three sizes of USB connectors are the default, or standard, format intended for desktop or portable equipment, the mini intended for mobile equipment, which was deprecated when it was replaced by the thinner micro size, all of which were deprecated in USB 3.2 in favor of Type-C. The mini and micro formats may connect to an AB receptacle, which accepts either an A or a B plug, that plug determining the behavior of the receptacle. A USB cable, by definition, has a plug on each end-one A (or C) and one B (or C)-and the corresponding receptacle is usually on a computer or electronic device. Each format has a plug and receptacle defined for each of the A and B ends. Thus, USB cables have different ends: A and B, with different physical connectors for each. Only downstream facing ports provide power this topology was chosen to easily prevent electrical overloads and damaged equipment. Unlike other data buses (such as Ethernet), USB connections are directed a host device has "downstream" facing ports that connect to the "upstream" facing ports of devices. USB has been selected as the standard charging format for many mobile phones, reducing the proliferation of proprietary chargers.Ĭonnectors Comparison of USB connector plugs, excluding Type-C plugs The USB standard included power supply to peripheral devices modern versions of the standard extend the power delivery limits for battery charging and devices requiring up to 240 watts. All versions of USB specify cable properties version 3.x cables include additional data paths. Higher-speed development of the USB standard gave rise to another family of connectors to permit additional data paths. The initial versions of the USB standard specified connectors that were easy to use and that would have acceptable life spans revisions of the standard added smaller connectors useful for compact portable devices.
Standard-A receptacle (inverted, so the contacts are visible, though extension cables are not allowed in USB).8-pin Mini-B plug, a proprietary connector used on many older Japanese cameras for both USB and analog AV output (This strongly resembles the 8-pin Micro-B plug which often has only 5 pin positions occupied.).The F1 terminal is thinner, and the F2 is wider. These terminal types are designed to be attached with a push-on spade insert, either for your application or for charging. These are flat blade type terminals which stick up at an angle from the top or side of the battery. The F1 and the F2 are the terms we use to refer to the terminals. The SLA batteries we sell, up to 12 volts 15 Amp Hours (AH), commonly use the faston tabs as the terminal type. These batteries are used in medical mobility wheelchairs, uninterrupted power systems (UPS), ride on toys for kids, razor scooters, and more. The terminal types that are going to be discussed here are commonly found on Sealed Lead Acid (SLA) Batteries. Car batteries have cylinder posts, motorcycle batteries have square posts, some are threaded, others are simple tabs sticking straight out of the top of the case. The F2 is 1/16" wider than the F1 terminal type.īatteries come in all shapes and sizes.
