2-640643-2

Rectangular Connectors - Accessories

The 2-640643-2 is a type of accessory used in connectors. It is used for providing signal and power connection and socketing for various devices. It is composed of two parts, one of which is a housing and the other is the insert. The housing-component is of plastic construction and is provided with a ridge ribbing to give added security when mated with the insert. It is also provided with latching lugs for butt-mating. The insert is composed of either metal or plastic and is designed to receive the contacts.

The 2-640643-2 connector is mostly used in automotive, industrial and telecommunications applications. In automotive wiring systems, it is mainly used to supply a wide range of signals and power contacts. It can be used for drive signal, power distribution, onboard diagnostic module, controlling onboard device, starting and stop engine, etc. In industrial applications, it is mainly used for relay applications, as well as for automation and control. Its advantages are its compact design, ease of assembly, and multiple contact configurations available.

Working Principle

The working principle of the 2-640643-2 connector is that it provides connection between two conductors for the transmission of signals. The two parts, housing and insert, are mated together to form a complete connection. The contact in the insert is crimped onto the wire, then the insert and housing are mated together and secured with locking lugs. When the wires and contacts are in place, signal and power are transmitted across the two connectors.

When power is supplied, the contact in the insert completes a circuit by connecting the two conductors. This causes a current to flow through the conductor, and the contacts and wires produce the signal. The contacts are also designed to provide electrical protection, such as EMI (electromagnetic interference) and ESD (electrostatic discharge) protection.

The 2-640643-2 connector is an important component of a wide range of electronic equipment, providing reliable connection of signals and power. It is easy to assemble and maintain and provides high levels of performance. It is also cost-effective and is available in multiple configurations, making it an ideal choice for a variety of applications.
