ESQT-148-03-L-D-375

ESQT-148-03-L-D-375 is a type of rectangular connector, defined as Header, Receptacle, Female Socket. It is widely used in the internal wiring of electronic devices due to its enhancement of both mechanical and electrical performances.

ESQT-148-03-L-D-375 is smaller than traditional connectors, but it still offers consistent electrical performance in harsh environments, better insulation resistance, and reliable contact insertion force. It offers quick and reliable connections between printed circuit boards or other components. It is designed with a 2.54mm grid arrangement.

Application field

The ESQT-148-03-L-D-375 connector is typically used in the internal wiring of electronic devices because of its finer pitch, which allows for a better space utilization. For example, this connector is widely used in applications such as computers, communications, consumer electronics and automobile electronics. It is suitable for wire-to-board and wire-to-wire connections.

Working principle

The ESQT-148-03-L-D-375 connector is a PCB connector composed of two parts, namely the Socket or Female part, and a Header or Male part. The Socket part contains many plasticized contact terminals which are inserted into the PCB surface while the Header part\'s contact terminals or pins are exposed for electrical contact.

The connector\'s basic working principle is as follows: In the Socket part, each contact terminal has its own channel or guideway that helps guide the pin or contact terminal from the Header part into the socket while also guiding it to its respective contact terminal. When the Header part is inserted into the Socket part, it is guided along the routes designed in the walls of the socket, ensuring that the contact terminals in the Header part are respectively lined up with the contact terminals of the Socket part.

The contact interface offers a reliable and secure connection between the two parts. The Faston or kinked contact design ensures a stable connection for a reliable and secure connection. The spring contacts also enable the contacts to self-adjust and compensate for any tolerance mismatches.

The ESQT-148-03-L-D-375 is also designed with multiple safety features. It is designed with an insulating body frame which safeguards against electrical shocks and provides excellent insulation between the two parts. It can also withstand various environmental conditions such as temperature, humidity, and high-frequency interference. Furthermore, the connector is designed to meet high-level standards for flame retardancy to meet UL 94V-0 requirements and achieve suitable protection.

In conclusion, the ESQT-148-03-L-D-375 connector is an excellent choice for electronic device internal wiring due to its enhanced mechanical and electrical performance, quick and reliable connections, and multiple safety features.
