Circular Connectors: MD-70 Application Field and Working Principle

Circular connectors are types of connectors commonly used in the fields of electrical engineering, electronics, and communications. They are used for power or signal transmission between two terminals on the same system, or to connect two systems together. The MD-70 is a circular connector designed and manufactured by Molex in 1976. It is primarily used in the automotive and medical industries as its features make it suitable for both these environments.

The MD-70 circular connector was created primarily for use in automotive and medical applications because of its robust housing, dependable connections, and compatibility with wire gauges ranging from 22 to 27 AWG. The connector is made up of two components, the connector housing and the crimp terminal, and both are available in a variety of sizes and colors. The housing is saved in black, green, yellow, or white and is hermetically sealed to prevent dust and water from entering the connection.

The connector housing is made from Nylon 6/6 and is designed with a sealing gasket and cap to keep the connection from collecting dust and debris. It also features a latch that provides a secure locking mechanism when the connector is assembled. The locking mechanism is designed to dislodge the connector in the event of an over-torque situation. The body of the connector contains three crimp terminals that can accommodate 22-27 AWG wires.

The second component in the MD-70 circular connector is the crimp terminals, which are available in different sizes and colors depending on the application. The crimp terminals are made from phosphor bronze and can withstand high temperature and environmental conditions. The terminals are pre-terminated with insulation options including heat-shrink, plastic sleeving, or shrink tubing. The terminals are then bolted or crimped into the connector housing through a plastic locking mechanism.

The MD-70 circular connector is a very reliable and secure connection. It has been successfully used in cars, medical equipment, air conditioning systems, and security systems. The ability to accommodate a variety of wire gauges and environmental conditions make it ideal for automotive and medical applications. Its main features such as the hermetic seal, locking mechanism, and wire assistance make it suitable for use in these industries. The MD-70 circular connector is reliable, secure, and designed to last in harsh environments.
