How connectors work

For connectors, you may not know more about them. The so-called connector is two or more containers that are connected to each other below the liquid level. Connecting devices containing the same liquid and equal pressure on the liquid surface have the same liquid surface height.

(1) The connector contains the same liquid, but the pressure on the liquid surface is not equal, then the pressure difference of the liquid surface is equal to the pressure difference generated by the liquid surface height difference between the two containers of the connector.

(2) The pressure on the liquid surface of the connector is equal, but there are different liquids that do not mix with each other on both sides. The height of the two liquid surfaces from the interface is inversely proportional to the liquid density.

The connector principle has a wide range of applications in engineering. Such as various liquid level gauges (water level gauges, oil level gauges, etc.), mercury vacuum gauges, liquid column air pressure gauges, differential pressure gauges, etc., are all made using the principle of the connector.

Understanding the definition and working principle of connectors will help us better understand and develop the connector market.

Basic properties of connectors

Connector knowledge The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance and environmental performance. Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a durability index, which is called mechanical operation in the national standard GB5095. It takes one insertion and one extraction as a cycle, and judges whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and extraction cycle.
