Backplane Connectors – Specialized

A backplane connector is a specialized form of connector commonly used in computer systems. As its name suggests, these connectors are typically connected to the main circuit board, known as a backplane, which interconnects multiple components. These components may include other backplanes, buses and memory chips. Backplane connectors are available in a range of sizes and shapes depending on the components being interconnected.

A backplane connector is typically made up of two separate parts, namely a plug and a receptacle. The plug portion is usually referred to as the male connector, while the receptacle portion is generally referred to as the female connector. The plug contains a series of pins which make contact with the female connector when the connector is connected. These pins may be arranged in either a straight line, or an arrangement called a dual in-line package (DIP). Depending on the type of backplane connector, the receptacle may have either a single row or two rows of pins.

51940-387LF is a product of Molex which belongs to the backplane connector.This connector can be divided into plug and receptacle. The plug is composed of 30 gold-plated metal pins and 5 plastic tongues. The receptacle is composed of 5 rows of 30 pins and 5 plastic tongues. When it is in operation, the plug is plugged into the receptacle. The plug and receptacle are connected. This type of connector has a transmission speed of up to 1.25Gbps and a rated voltage of up to 2A.

The main application of Molex 51940-387LF is for Ethernet switches and routers. It ensures that there is reliable data transfer between the main control board and other devices. The transmission link is reliable and the data can be transmitted in a short time. In addition, this connector provides a strong link between the components by reducing the current flux to a minimum. Moreover, it also helps to reduce interference from external sources such as ESD, EMC and other EMI.

The working principle of Molex 51940-387LF is quite simple. Firstly, a plug is inserted into the receptacle to establish a positive contact. This is done by pressing down on the plug and turning it clockwise until the tab on the receptacle locks into the groove on the plug. When the connectors are properly mated, any changes in the alignment of the connectors will be minimal. Secondly, the pins on the plug and receptacle make contact with each other, allowing data to be transferred. Finally, a mechanical and electrical connection is established, allowing data of up to 1.25 Gbps to be transferred between the components.

In conclusion, the Molex 51940-387LF is a specialized backplane connector which has a transmission speed of up to 1.25 Gbps and a rated voltage of up to 2A. It provides reliable data transfer between the main control board and other devices, while also helping to reduce interference from external sources. This connector is commonly used for Ethernet switches and routers. Its working principle is quite simple, involving the insertion of a plug into the receptacle to establish a connection, followed by the transfer of data.
