Power connectors, as an indispensable key component in electronic equipment, are mainly used to connect power devices with target electronic devices or circuits to achieve safe and efficient transmission of power. It usually consists of plugs and sockets with the convenience of quick plugging and unplugging, and is designed with protection mechanisms to prevent short circuits, overloads and overheating.

In the connector industry, many well-known brands lead the market with their superior technology and product quality. For example, Tyco, as the world's largest connector manufacturer, has products that are widely used in a variety of fields such as consumer electronics, power, medical, automotive and aerospace, etc. TE Connectivity (TE), on the other hand, with annual sales of $14 billion, offers about 500,000 types of connector products, covering the needs of almost all industrial sectors.

Molex as the world's leading supplier of a full range of interconnect products, especially known for the development of the world's smallest connectors, and in recent years more to the antenna, switches, LEDs and other directions to further broaden its product line. Amphenol (Amphenol) is through a series of mergers and acquisitions, the integration of the world's top connector manufacturers resources, in the military, aviation, aerospace and communications field to occupy a dominant position.

Power connector industry is full of jargon, such as ‘contact centre distance’ refers to the contact on the installation of the central position, ‘contact resistance’ refers to the typical conditions of use, the maximum allowable resistance between the pins and jacks. These terms not only reflect the delicate and complex design of the connector, but also reflect the industry's strict requirements for quality and performance.

In addition, power connectors follow a series of international standards, such as USB, DC plugs and IEC standard power connectors, to ensure compatibility between different brands of equipment. These standards not only promote the popularity and application of products, but also promote the healthy development of the whole industry.

In summary, power connectors, as an important part of the connector industry, not only carries the heavy responsibility of power transmission, but also integrates the technology and wisdom of many world-renowned brands. With the continuous progress of science and technology and the continuous expansion of application areas, the future of power connectors will undoubtedly be brighter.
