Backplane Connectors - Specialized: 6643439-1 application field and working principle

Backplane connectors are a type of specialized component used to make electrical connections between components and backplanes in today’s electronic products. In order to ensure reliable operation, these backplane connectors must be able to support high-speed signals and power, in addition to having low thermal resistance. As a result, manufacturers have developed several different types of backplane connectors, each with a specific application field and a unique working principle.

The 6643439-1 is one such type of backplane connector. It is a low-profile, high-precision connector designed for high-speed data connections. It is typically used in communications, computer, networking, A/V, industrial, security, and aerospace applications.

The 6643439-1 utilizes a three-metallic-piece design, consisting of two halves of polarized contact pins and a third piece of an electrically conductive circuit element. This design ensures reliable electrical connection between components in harsh environments. The contact pins are press-fit and are self-aligning, allowing for automated insertion and removal. In addition, the contact pins use a floating contact design that eliminates contact pressure and provides reliable contacts.

The 6643439-1 has a contact termination type of crimp and is available in two sizes: 38mm and 50mm. It has a housing material of nickel plated brass, while the contact pins are a combination of gold plated Beryllium Copper and Phosphorus Bronze. It is rated for contact current up to 5 amps, voltage up to 250 volts, and temperature range of -55C to +125C. It is also designed to be low-EMI compliant, and provides a seal with a silicone O-ring.

The 6643439-1 utilizes a unique feature called the Shield Stop, which automatically locks the mounting screws of the connector into position. When the mounting screws are properly tightened, the Shield Stop creates a secure, dust-free environment inside the connector. As a result, the connection between the 6643439-1 and backplane is extremely reliable.

The 6643439-1 is ideal for system designs that require high-density connections with high-speed and power support. It can be used in applications ranging from aerospace and industrial to computer and networking, and it provides users with reliable, low-profile connections. With its locking Shield Stop feature and reliable contact pins, the 6643439-1 is a perfect fit for applications where vibration and temperature are concerns.
