If the connector contains the same liquid, but the pressure on the liquid surface is different, then the pressure difference on the liquid surface is equal to the pressure difference caused by the difference in liquid level between the two containers of the connector.
The connector has equal liquid pressure, but different liquids on each side, and the height of the two liquid surfaces at the interface is inversely proportional to the liquid density.
The connector principle has wide applications in engineering. Various liquid level gauges (water level gauges, oil level gauges, etc.), mercury vacuum gauges, liquid column barometers, differential pressure gauges, etc., are all made using the connector principle.
Understanding the definition and working principle of connectors helps us better understand and develop the connector market.
Basic performance characteristics of connectors:
The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Mechanical life is also an important mechanical performance characteristic. Machine life is actually a durability indicator, which the national standard GB5095 refers to as machine operation. It is measured in cycles of insertion and removal, and the criterion for judgment is whether the connector can normally complete its connection function (e.g., contact resistance value) after a specified number of insertion and removal cycles.
What is a connector? A connector is an electronic component that connects the flow of electricity and electrical signals. It's a component that electronic engineers frequently encounter. In China, it's also called a connector, plug, or socket, generally referring to an electrical connector. That is, a device that connects two active devices to transmit current or signals. There are many connector brands, both domestic and international.
Connectors are not static; their form and structure vary greatly depending on the application, frequency, power, and environment. For example, there are network connectors, industrial connectors, electronic connectors, mobile phone connectors, and computer connectors, each used in different fields. For instance, the connectors used for stadium lighting, hard drive connectors, and rocket ignition connectors are vastly different. However, regardless of the type of connector, it must ensure a smooth, continuous, and reliable flow of current.
The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance.
1. Mechanical properties. In terms of connection function, insertion and extraction force is an important mechanical property. Another important mechanical property is the mechanical life of the connector.
2. Electrical Performance. The main electrical performance characteristics of connectors include contact resistance, insulation resistance, and dielectric strength, as well as other electrical properties. For RF coaxial connectors, there are also electrical indicators such as characteristic impedance, insertion loss, reflection coefficient, and voltage standing wave ratio (VSWR). In addition to characteristic impedance, some new electrical indicators have emerged, such as crosstalk hysteresis.
3. Environmental performance. Common environmental performance characteristics include temperature resistance, humidity resistance, vibration resistance, and shock resistance. Depending on the application requirements, there are other environmental performance characteristics, such as airtightness and resistance to low atmospheric pressure.
What is a connector?
An electrical connector is an electromechanical component used to connect wires, cables, and control panels (compartments). It consists of two parts: a free-end electrical connector and a fixed electrical connector. The connection and disconnection of these parts create the circuit's continuity. Electrical connectors are also simply called connectors.
Fixed electrical connector: A passive connection part installed on the panel and base (or not installed). It is a component of the electrical connector and is also known as a socket.
Free-end electrical connector: The active connection part that mates with the fixed-end electrical connector and has a connecting nut or other locking device. It is a component of the electrical connector and is also known as a plug.
Because electrical connectors consist of a plug and a socket, they are also called plug-and-socket connectors. Furthermore, since circuit connections are primarily achieved through their mating, electrical connectors are also commonly known as connectors or plug-ins.
What is the structure of a connector?
a) Contact: A conductive component with one end for insertion and the other end for terminating a wire. Also known as a pin or socket;
b) Insulating mounting plate: An insulating component that supports and positions the contact parts. Also known as an insulator;
c) Housing: Parts that house the insulating mounting plate and contacts;
d) Locking mechanism: Provides a device for locking and preventing loosening of the plug and socket;
e) Tail accessories: Accessories or parts attached to the end of a plug or socket to secure and clamp wires or cables, such as cable covers, cable clamps, etc.
What are the characteristics of connectors?
Connectors come in a wide variety of types and structures, but they should generally have the following characteristics:
a) High interchangeability: electrical connectors of the same model, type, specification, and batch or different batches can have their plugs and sockets interlocked and achieve the required electrical, mechanical, and other performance characteristics;
b) Excellent tactile feedback, making operation feel comfortable and smooth;
c) Anti-misinsertion function;
d) A reliable locking and anti-loosening mechanism;
e) High safety: such as sufficiently high insulation resistance and withstand voltage;
f) High overload resistance;
g) High reliability and stability;
h) Good resistance to environmental conditions.
What is a connector? A connector, also often called a circuit connector, is, as the name suggests, a conductor device that bridges two conductors in a circuit, allowing current or signals to flow from one conductor to the other. An electronic connector is an electrical system that provides a separable interface for connecting two electronic systems. Simply put, a connector is a component used to complete the electrical connection between circuits or electronic devices; it is the bridge between them.

Connector Classification
The positioning connector for linking electronic circuits consists of two parts: the plug and the connector (such as a charging connector and a plug). Common connectors typically include the following two main parts.
1. Terminal block
A terminal, also known as a metal terminal, is used for conduction. It has holes at both ends for easy connection of wires.
2. Terminal housing
It is often simply called a shell, and is mostly made of plastic. It serves a protective function and acts as a nail for the terminal, used in conjunction with the terminal.
