      Principle of connector

      Date of release:2018-09-06 16:42   Browse volume:
      A connector is a detachable element (except a adapter) that is usually mounted on a cable or device for electrical connection to a transmission line system. It is also referred to as connectors, plugs and sockets in China. Generally refers to electrical connectors. A device that connects two active devices to transmit current or signal. A connector is a motor system that provides a separable interface to connect two sub-electronic systems and has no unacceptable effect on the operation of the system. The key word in the definition is "electrical system", "separable" and "unacceptable role". A connector is a motor system because it is an electrical connection produced by mechanical means. As will be discussed, the deflection of the mechanical spring produces a force between the two parts of the mating, which causes a metallic contact between the mating surfaces of the interface.
      The principle, classification and type naming of connectors
      The main reason for using connectors is that the interface is separable. There are many reasons for the need for separability. It can make parts or subsystems independently, and final assembly can be carried out in a major place. Separability also enables maintenance or upgrading of parts or subsystems without modifying the whole system. Another reason for separability is portability and support for the expansion of peripherals. On the other hand, separability in the definition introduces an additional interface between subsystems that does not introduce any "unacceptable effects", especially on the system's characteristics that are not affected by telecommunications, such as unacceptable distortions and signal degradation between systems, or through connectivity. The power loss of the adapter, which is calculated by millivolt loss, will become the main design criterion for functionality, so the power demand for the motherboard will increase.
      The limits of separability requirements and "unacceptability" depend on the application of connectors. Separability 4 includes the number of mating cycles, which refer to the forces that must be provided by the connector without affecting its performance and that are necessary to match another connector. Typical fit cycles range from dozens of cycles for internal connectors to thousands of cycles for peripherals, such as PCMCIA connectors. As the number of circuits or functions and the number of connectors connected to each other increase, the need for coordination becomes more important. In order to provide more functionality, the position of the upper terminal of the connector must also be increased, which leads to higher coupling strength. Depending on the use and function of connectors, the number of terminals ranges from tens to thousands.
      The principle, classification and type naming of connectors
      The principle of connectors:
      The so-called connectors are two or more containers that are interconnected below the liquid level.
      The connector holds the same liquid, but the pressure on the liquid surface varies, so the pressure difference on the liquid surface is equal to the pressure difference caused by the height difference between the two containers of the connector.
      The pressure on the liquid surface of the connector is equal, but there are different liquids on both sides. The height of the two liquid surfaces from the interface is inversely proportional to the liquid density.
      The principle of connectors is widely applied in engineering. For example, all kinds of liquid level meters (water level meters, oil level meters, etc.), mercury vacuum meters, liquid column air pressure meters, differential pressure meters, etc., are made by using the principle of connectors.
