Development history of power connectors

When electricity becomes a common item in the home, its main purpose is to provide illumination for the family. The power company at the time realized this difference and set different price standards for lighting and non-lighting. However, this price differentiation led people to connect various household appliances to their lighting sockets through the lamp holder plugs.

Electricity has become more commonplace in the home for many years, driving the need for a safer way to connect electrical appliances to electrical systems. From the late 1890s to the early 20th century, many inventors around the world mapped many different connector designs. Although the basic uses of these connectors are the same, their design details are different, and this difference also leads to subtle differences in their methods of operation. For example, among the plugs originally designed by Americans, there is a plug with a hook that helps to secure the plug, preventing it from being accidentally pulled out.

It was during this period that the people involved in the development of these new electrical systems, mainly engineers and scientists from different countries, realized the necessity of a standard system. In 1906, the International Electrotechnical Commission (IEC) was established. The establishment of this committee provided engineers and scientists with a platform to share their expertise and research results, thus promoting the development of electrical system development.

Over time, more different versions of the early power connectors were developed. These changes include the development of more adapter types that can be used with existing light sockets or any other common socket. During this period - from 1900 to 1910, many changes took place, including rotating the pins 90 degrees, which is also a structural design that is widely used today.

However, starting in 1911, people began to realize that it was necessary to make some changes to the connector at the time. It is now difficult to know who first made or designed the first "common ground" plug, but it is generally believed to have been invented between 1911 and 1928. The so-called ground plug is what we now call the grounding plug, also known as the "three-legged" plug in the United States. This grounding plug uses a third pin that is longer than the other two pins to ensure that the power is connected before grounding. This allows any excess power to flow through the ground pin to the ground without reaching the user. This change to standard connectors has driven the need for more stable and safe electrical systems, which is why grounding connectors have become the new standard and are still in use today.

In the first few decades of the beginning of the use of electricity, relevant standards began to change and develop rapidly, especially after the increasing use of commercial electricity. In addition to commercial use, economic factors also have an impact on the changes and formation of these standards. This period is the time when different countries began to manufacture various commodities and trade with other countries around the world. As the desire for and ease of trading of goods grows, standards that are not widely used begin to shrink and eventually become unused.

In the years following the Second World War, different countries developed their own standards and implemented them, but this is not a unified international standard. Part of the reason for the different standards is that, globally, not every country needs a particular style of connector, nor do they need to ensure that their systems are compatible with other systems.

Discussions on the use of a more universal system began in the early 1970s and continued until the late 1990s. Although some regions, such as Europe, have developed power connector systems that can be used in different European countries, they have not been promoted to become internationally harmonized standards. Although people have tried to develop a set of internationally uniform standards, only a few countries have actually implemented them.

A few inventions or discoveries have changed or shaped the historical process of people using electricity. Power connectors are still a vital part of the system, although their style and functionality have been changed and adjusted in recent decades. Through an in-depth understanding of the history of power connectors, the economic and social drive for scientific development is even more apparent.
