Blade type power connectors have been used in many industries since the late 20th century. The 647845-5 connectors are among the most popular. This article outlines the application fields and working principle of this specific connector.

Connector Application Fields

The 647845-5 connectors are mainly used in the automotive, marine, aerospace and military industries. Usually they are used in high-vibration, high-current, and/or high-frequency applications. They are especially used to join wire bundles with relatively large current ratings.

In addition to the main application fields, 647845-5 connectors are also used in various other equipment due to their reliable performance. For instance, they can be used in electric motors, braking systems, air-conditioners, computers, cell phones, and audio-visual equipment.

Connector Working Principle

The 647845-5 connector is a two-piece connector featuring an insulative housing and a conductive blade. The connector’s blade type design enables the blades to securely grip the wire bundles and prevent them from slipping out. The contact area on the inner side of the connector is plated with a highly conductive metal, such as silver or gold. This improves the electrical conductivity and helps reduce contact resistance. The blades also have a protective black oxide finish to guard against corrosion.

The connector’s housing is made of thermoplastic, and has a ribbed design that reinforces the mechanical strength and offers a great amount of protection against environmental factors such as dust, moisture and corrosion. The connector also comes with a sealing gasket which helps provide a watertight seal and further improves the protection.

The 647845-5 connector is manufactured according to the IEC/EN standards. All the parts are designed to be as small as possible, allowing them to be used in tight space restrictions. The pins on the blades are designed to fit standard round cables as well as ribbon cables.

Conclusion

The 647845-5 blade type power connector is a reliable and versatile solution for various industries. It is especially used in high-vibration, high-current, and/or high-frequency applications with great success. The well thought out construction of the connector ensures excellent performance, all the while remaining small enough for tight installation spaces. The connector is also compliant with all IEC/EN standards, and is designed to fit both round and flat cables.
