Plug type A

Used in: North and Central America, Japan

The Type A electrical plug (or flat blade attachment plug) is an ungrounded plug with two flat parallel pins. Although the American and Japanese plugs appear identical, the neutral pin on the American plug is wider than the live pin, whereas on the Japanese plug both pins are the same size. As a result, Japanese plugs can be used in the US but often not the other way around.

The pins on Type A and Type B plugs have a hole near the tip that fits into ‘bumps’ found on the contact wipers of some sockets, so that the pins are gripped more tightly allowing for better contact and also to prevent the plug from slipping out of the socket. Some sockets have spring-action blades that grip the sides of the pins, making the holes obsolete.

Plug type B

Used in: North and Central America, Japan

The Type B electrical plug has two flat parallel pins and a round grounding (or earth) pin. The earth pin is longer than the other two so that the device is grounded before the power is connected. As with the type A plugs, the American and Japanese versions vary slightly.

Type B plugs are rated at 15 amps.

Plug type B by IEC

Plug type F

Used in: Germany, Austria, the Netherlands and Spain among others

The Type F electrical plug (also known as a Schuko plug) has two 4.8 mm round pins spaced 19 mm apart. It is similar to the Type E plug but has two earth clips on the side rather than a female earth contact. The CEE 7/7 plug was developed to work with sockets E and F and has grounding clips on both sides (to work with Type F sockets) and a female contact (to accept the grounding pin of the type E socket).

Type F plugs are rated 16 amps.

10A

220 – 240 V

与I型插头兼容

Used in: Australia, New Zealand, Papua New Guinea, Argentina

The Type I plug has two flat pins in a V-shape as well as a grounding pin. A version of the plug, which only has the two flat pins, exists as well. The Australian plug also works with sockets in China.

Australia’s standard plug/socket system is rated 10 amps but a plug/socket configuration rated 15 amps also exists, although the ground pin is wider. A standard 10 amp plug will fit into a 15 amp socket but not the other way around.
