202650-4 Backplane Connectors - Housings Application Field and Working Principle

Backplane connectors and housings are a type of electrical connector used to make connections between printed circuit boards (PCBs). The connections allow the electrical signals from one PCB to another. A backplane connector and housing is typically manufactured with rigid plastic, often referred to as plastic injection molding. The contacts are usually made from metal and are plated with a conductive material such as gold or silver.

The 202650-4 backplane connectors and housings are designed for high-performance signal transmission. The contacts are engineered to enable reliable, low-skew signal transmission frequency up to 15GHz. With improved pin count and ground loop reduce, this connector provides superior signal integrity and interference immunity.

The main application field of the 202650-4 backplane connectors is in high-speed communication systems as they are suitable for applications that require high-speed transmission. They can be used in various types of communications-related systems, such as 10 Gb/s optical communication systems, or 10 Gb/s Ethernet systems. They are designed for both adding and deleting applications with their high-frequency characteristics. This connector also has a mechanism to facilitate easy handling and plug-in without influencing the signal integrity.

The working principle of the 202650-4 backplane connectors and housings is based on the electrical contact between two metallic components. The contact consists of a pin or male connector which is inserted into a female connector or socket. The pin and socket are kept firmly in place by the two halves of the housing, which are attached together with screws. The contact is made by the metallic surfaces of the pin and socket rubbing against each other. This generates friction heat, which is dissipated by air around the contact, preventing damage due to excessive heat.

The contact is additionally protected from oxidation and corrosion by the insulating material, which covers the contact surfaces. This insulating material is also necessary to prevent any short-circuiting due to the static charges and high-voltage surges. Additionally, the insulation helps to ensure reliable connection even in severe environments.

In summary, the 202650-4 backplane connectors and housings offer a great solution for high-performance signal transmission, and are suitable for use in a wide range of communications-related systems. With its rigid plastic structure, pin contact protection, and insulation, this connector ensures reliable connections even in severe environments.
