Terminals - Wire to Board Connectors includes many different types of connectors that are designed to interconnect, join, or terminate conductors and circuits in an electrical system. Among these connectors, the 640311-5 terminal is a very popular one. This article explains the application field and the working principle of 640311-5 terminal.

Application Field

The 640311-5 connector offers excellent features for a wide range of applications. It is a great choice for harsh environments as it is designed to be extremely robust and reliable. It is perfect for applications requiring high-voltage power connections with high current capacity, such as connecting equipment in the outdoors. It is also ideal for applications where higher power is needed, but space is limited, such as in automotive, telecommunications, and industrial applications. Additionally, this connector is suitable for use in applications with vibration or frequent disconnect/reconnect, as the terminal\'s contact force helps to absorb impacts.

Working Principle

The 640311-5 terminal uses a crimp contact method to connect solid conductor wires to printed circuit boards (PCBs). It is equipped with a double-spring mechanism for a secure electrical connection. The terminal consists of a box-type housing, a solid conductor socket, a locking mechanism and a contact spring on each side. The locking mechanism provides a simple and secure connection between the wire and PCB. The contact spring has a tapered contact area that increases the contact force when the wire is inserted. This ensures an excellent electrical connection between the wire and PCB, providing reliable performance even in harsh environments.

The housing also has a strain relief design to provide additional protection for the connection. The strain relief prevents the connection from being damaged due to vibration, pulling, or bending forces. Additionally, the housing is made of durable and flame-resistant materials, providing superior environmental protection against environmental exposure. The connector also has a compact design, making it easy to install in limited spaces.

The 640311-5 terminal is a reliable and versatile connector that can be used in a variety of applications. It offers excellent features such as high current capacity, strong contact force, robust construction, and reliable performance even in harsh environments. Its compact design makes it easy to install and its strain relief provides additional protection ensuring that the connection remains secure in all conditions.
