Modular connectors, more commonly referred to as jacks, are among the most widely used electronic connectors in the world. From telecommunication jacks to coaxial connectors, these versatile devices are found in almost any context where the transmission of electrical signals is required. The 5555141-3 jack is a popular type of modular connector that finds use in a variety of applications. This article covers the application field and working principle of the 5555141-3 jack.

The 5555141-3 jack is a 4-pin MIL-C-38999 style Type I (Series III) plug connector that is suitable for use in various electrical and electronic applications. It is widely used in military-grade electronic equipment, including communication systems, navigation systems, and radar systems. The plug connector is also used in medical electronic components and military aircraft components. Its rugged construction makes it ideal for applications where vibration, shock, or extreme environmental conditions are present.

The 5555141-3 jack is manufactured with gold-plated high quality brass contacts and a zinc-nickel plated steel shell. The contact arrangement is three pins and one grounding contact. The contact pins are surrounded by a thermoplastic insulating housing that prevents contact between pins. The plug is then secured to the plug body with a molded, tamper-resistant locking nut. The shell of the plug is threaded to receive a threaded anti-vibration retainer. Together, these features ensure that the connector is durable and reliable.

The working principle of the 5555141-3 jack is fairly simple. In order to connect two components, the plug is first inserted into a mating socket. The force of insertion causes the contact pins on the plug to interact with the contact surfaces of the socket. This connection forms a completed electrical path between the two components, allowing them to transmit electrical signals. The locking nut on the plug ensures that it is securely attached to the socket and prevents accidental disengagement.

The 5555141-3 jack is an essential component for a variety of applications, ranging from communication systems to medical electronics. Its rugged construction and durable contacts make it well-suited to use in high-vibration environments, while its secure locking nut ensures that the connection is reliable and secure. Its simple working principle and wide range of applications make it one of the most widely used modular connectors on the market.
