Definition of 2.92mm Connectors

In the RF and microwave fields, connectors are often named according to the diameter of the connector interface for ease of identification and standardization. 2.92mm connectors, because of the connector interface is 2.92mm in diameter. 2.92mm connectors are also commonly referred to as K-type connectors, which derives from their compliance with Electronic Industries Alliance standard EIA-297. In this standard, 2.92mm connectors are defined as K-type connectors. In this standard, 2.92mm connectors are defined as Type K connectors, a nomenclature that probably comes from the German word "Klein" meaning "small" to distinguish them from larger connector models. Despite being called K-connectors, this designation is not very common, and it is usually more common to refer to them as 2.92mm connectors.

Explore the Internal Structure of the 2.92mm Connectors

The 2.92mm connectors are the precision coaxial connector whose basic structure consists of a housing, a center pin, an insulator and an external shield.
 

Housing

The housing of the connector is usually made of metal and has a threaded structure. This design allows the connector to be securely screwed to other equipment or connectors, ensuring a solid connection. The surface of the housing is usually treated with nickel or silver plating to improve its corrosion resistance and external shielding performance.
 

Center pin

The connector has an internal center pin, usually made of metal, which is responsible for transmitting the signal. The center pin is located in the center of the connector and is connected to the external device through an internal hole in the connector.
 

Insulator

The insulator is located between the center pin and the external shield and acts as a separator and support. It is usually made of plastic or ceramic material to prevent short-circuiting between the signal and the external shield.
 

External Shield

The external shield is wrapped around the internal center pin and is used to shield against external interference and protect the signal from damage. It is usually made of metal and is tightly connected to the outer case to form a complete shielding structure.
