ESD-110-G-03 is a series of rectangular connectors divided into headers, receptacles, and female sockets, which are used to transmit electric signals and data in different power and control applications. This article will focus on the detailed application field and working principle of this type of connector.

Application Field of ESD-110-G-03

ESD-110-G-03 is mainly used in indoor and outdoor lighting, audio/video systems, automotive and industrial electronic control systems, power supply, medical equipment, charging piles, automation equipment, mobile communication equipment, etc. Its tongue and groove design ensures that it is dust-proof, waterproof and vibration-proof. The high-temperature nylon plastic body can resist temperatures of up to 105℃ and the contact of phosphor bronze ensures low contact resistance. The small size of the connector makes it ideal for high-density applications.

Working Principle of ESD-110-G-03

In the most common form of application, the device takes the form of a header and a socket. The header is composed of contact pins on the male side, and the socket is composed of contact terminals on the female side, as shown in the diagram. To connect the two, a mating force needs to be applied to insert the header into the socket, and the contact pins are in contact with the contact terminals. With the help of the positive and negative actuation force, the contacts are pushed onto the contact terminalsto achieve an electrical connection. When the two parts are released, the contact terminals remain pressed against the contact pins due to the actuation force, thereby maintaining electrical contact. The device is also equipped with a locking mechanism to prevent accidental disconnection.

In conclusion, ESD-110-G-03 is a type of rectangular connector divided into headers, receptacles, and female sockets. It is widely used in various types of electrical applications and is especially suitable for high-density applications due to its small size. Its working principle is composed of two parts: the header is composed of contact pins and the socket is composed of contact terminals. When the contact pins are in contact with the contact terminals, a current connection is established, and the device is also equipped with a locking mechanism to protect it against accidental disconnection.
