ESQT-137-03-MM-Q-309 Rectangular Connectors - Headers, Receptacles, Female Sockets

ESQT-137-03-MM-Q-309 are rectangular connectors, specifically headers, receptacles, and female sockets. They belong to the family of rectangular connectors, which are connectors with rectangular shaped terminals used in a variety of applications.A rectangular connector is a form of electrical connector used for connecting electrical cables or wires to electrical devices. It can be used in various applications in the automotive, computer, communications, mobile, medical, and military fields. It consists of two parts: the male part and the female part. The male part is composed of a set of pins and is typically mounted on a printed circuit board (PCB) while the female part consists of a set of sockets which can accept the male pins.When placed in the male part, it is typically secured by a locking mechanism which prevents it from being accidentally disconnected from the board. The female part is usually secured by a pair of clamping devices which fasten the connector firmly to the cable.ESQT-137-03-MM-Q-309 connectors are specifically designed for use in the automotive, computer, mobile, communications, military, and medical fields. These connectors are designed to provide a secure connection between an electronic device and its power point, and between the power point and the cable.The working principle of this type of rectangular connector is simple: the male part is inserted into the female part which securely clamps it into place. The pins on the male part are designed to fit through the sockets on the female part. Once fitted in the sockets, the pins can then be secured by compression so that they cannot be pulled out or disconnected. Once the pins are secure, a lock can be engaged on the connector to ensure it stays in place.The pins are designed in such a way that they provide a secure connection between the electronic device and the power point. They are the points of contact between the two and the current is conducted through these pins. The pins also help protect the components against friction and corrosion that could potentially cause damage to the device.Due to its many features, ESQT-137-03-MM-Q-309 connectors are widely used in the automotive, computer, communications, mobile, military, and medical fields. It is a reliable and affordable way to ensure a secure connection between an electronic device and its power sources and also helps protect those components from damage.
