We provide all kinds of socket plug

we provided all type of socket plug,please see the refer plug from the link:https://www.worldstandards.eu/electricity/plugs-and-sockets/ab/


Type A

This class II ungrounded plug with two flat parallel prongs is pretty much standard in most of North and Central America. It is known as NEMA 1-15 and was invented in 1904 by Harvey Hubbell II. The plug has two flat 1.5 mm thick blades, measuring 15.9 – 18.3 mm in length and spaced 12.7 mm apart. Type A plugs are generally polarised and can only be inserted one way because the two blades do not have the same width. The blade connected to neutral is 7.9 mm wide and the hot blade is 6.3 mm wide. This plug is rated at 15 A. Since 1965, ungrounded type A outlets are not permitted anymore in new constructions in the United States and Canada, but they can still be found in older buildings.


Type B

This class I plug is designated as American standard NEMA 5-15. It has two flat 1.5 mm thick blades, spaced 12.7 mm apart, measuring 15.9 – 18.3 mm in length and 6.3 mm in width. It also has a 4.8 mm diameter round or U-shaped earth pin, which is 3.2 mm longer than the two flat blades, so the device is grounded before the power is connected. The centre-to-centre distance between the grounding pin and the middle of the imaginary line connecting the two power blades is 11.9 mm. The plug is rated at 15 amps.


Type E

Type E is primarily used in France, Belgium, Poland, Slovakia, the Czech Republic, Tunisia and Morocco. (Click here for the full list of all countries that use type E)

France, Belgium and some other countries have standardized on a socket which is different from the CEE 7/4 socket (type F) that is standard in Germany and other continental European countries. Fortunately, type F plugs are fully compatible with type E sockets and the other way round. In the past, however, this wasn’t the case. The reason for the initial incompatibility was that grounding in the E socket is accomplished with a round male pin, which is permanently mounted in the socket. Old type F plugs did not have a grounding hole to accept the earth pin of the type E socket. This grounding pin is 14 mm long and has a diameter of 4.8 mm. The plug itself is similar to C except that it is round and has the addition of a female contact to accept the socket’s grounding pin. The plug has two 4.8 mm round pins, measuring 19 mm in length on centres spaced 19 mm apart. The centre-to-centre distance between the female contact and the middle of the imaginary line connecting the two power pins is 10 mm.
