What materials are used in plugs?
Table of Contents
A plug consists of the case or cover, three pins, a fuse and a cable grip. The case of a plug is the plastic or rubber parts that surround it. Plastic or rubber materials are used because they are good electrical insulators. The pins inside the plug are made from brass because brass is a good conductor of electricity.
What plastic is used to make A plug?
ABS is used for one piece plugs because thermoplastics can be easily joined after moulding.
What does 13A mean on A plug?
Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). For example: 13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron.
What are the things you put plugs in called?
Also referred to as a “socket strip”, “socketboard”, “power strip”, “extension socket”, “extension cable”, “plug board”. Probably a few other things. They’re called ‘power-boards’ in Australia.
What metal is used in plugs?
Copper and brass resist corrosion and are good electrical conductors. Copper is a better conductor than brass so it is used in electrical wiring. Brass is stronger than copper. Suggest why brass, not copper, is used for the pins on electrical plugs.
Which material is used in plug and switch?
Bakelite is a thermosetting plastic and is used for making electrical switches, handles of various utensils, etc.
What are three pin plugs made of?
The 3-Pin plug connector pins made from brass, because brass is a good conductor; a fuse (3A, 5A and 13A are the most common values); an earth pin; a cable (or cord) grip to hold the cable firmly in place and stop a user pulling wires free from their correct connections.
Why is plastic a good material for an electric plug?
Electrical plugs are made up of plastic because plastic protects people from electricity. As we know that plastic is an electrical insulator readily available and cheap. So as to make the plugs shock free, they are made up of plastic.
What voltage is a 13amp plug?
Standard 13 amp Plug to 3 pin 230 volt, 16 amp, Female Inline Socket c/w fly lead (max. load 13 amps). Manufactured with 300mm cable and standard 13 amp plug (max. load 13 amps).
Can I use a 5A fuse in a 13A plug?
If 13A is the maximum allowable, then it could well be the case that the normal operation of your heater is > 5A, which would blow your 5A fuse immediately. It’s not safe to operate a heater without the appropriate fuse. Rep:?
What is A plug board called?
patchboard in British English. (ˈpætʃˌbɔːd) or patch panel. noun. a device with a large number of sockets into which electrical plugs can be inserted to form many different temporary circuits: used in telephone exchanges, computer systems, etc. Also called: plugboard.
What is a 13A plug?
Case Study Product Analysis: The 13A Plug The 13A plug is perhaps the most common electrical component we use; it retails for under a pound, contains numerous parts and together with the cable and socket is an essential part of almost every household electrical device.
What are the most critical components in a plug?
The pins are perhaps the most critical components in the plug. Before we can decide what materials to use, we must look in more detail at the requirements placed upon them. Requirements for a pin
How do I choose the right Plug material?
To hold the pins securely and to protect the conducting parts, the plug body must be sufficiently strong and stiff. Plugs are also likely to suffer impacts, so toughness may also be a factor in material choice.
Why are only 2 types of plug materials used in plugs?
Plug body: selecting the material Also, out of all the polymers available, why are only 2 commonly used? To hold the pins securely and to protect the conducting parts, the plug body must be sufficiently strong and stiff. Plugs are also likely to suffer impacts, so toughness may also be a factor in material choice.
