The concept and introduction of electrical connectors
Electrical connectors are all kinds of electrical, electronic systems indispensable electronic components, widely used in aerospace, aviation, nuclear industry, weapons, ships, electronics, transportation, computers, communications, medical, oil exploration and other industries. Electrical connectors as the electrical signal transmission system “nerve hubs and contacts” in the circuit plays a key role in the transmission of electrical signals bridge, its quality directly affects the performance and quality of products.
Definition of electrical connector
Electrical connectors are mainly used for electrical and electronic equipment cable line and cable line, cable line and equipment between the circuit connection, to achieve low frequency signals, high frequency signals and electrical energy (power) transmission. Electrical connectors are composed of two parts: fixed electrical connectors and free end electrical connectors.
Fixed electrical connector is installed in the panel and base (or not installed) passive connection part, also known as the socket; free end electrical connector is with a connection nut or other locking device active connection part, with the fixed end of the electrical connector, also known as the plug. Electrical connector through the plug and socket between the insertion and separation, so that the circuit on and off.
The electrical connector consists of three basic units: shell, insulator, and contact body.
(1) Shell
Electrical connector shell by the plug / socket shell, connection nut, tail accessories, the role of each part is.
