There are many types of connectors, which appear in every corner of us. Maybe we use connectors inadvertently. What exactly is a connector? In fact, we can understand it by taking the items in our home, such as the plug of the desk lamp, the interface of the U disk, and the jack of the earphone. These are small connectors; and the large ones have the controls in the car. Equipment, optical fiber docking terminal, are you familiar with it?
As a necessary product of electrical equipment, the main characteristic and function of the connector is connection and conduction. The conductivity of metal is the most prominent among many materials, so the status of use cannot be shaken. But metal also has its own “personality”. In physics, this “personality” is called resistance, which is an item that cannot be ignored in the electrical performance of the connector.
There are many classifications of electrical resistance. What we mainly talk about today is the analysis of the electric strength of the connector. The transmission of signals requires the loading of electric waves to complete, using the transport capacity of electricity in conductors. And if there is interference or poor operation during the current transmission, just like a boat sailing in the river, there will be errors and loss of signals, and this situation must be dealt with. If the interference situation is to be solved, it is necessary to keep the current completely in the transmission line without being interfered by other signals. The solution to this situation is to add an anti-electromagnetic interference shielding device to the docking part of the connector. During the test, a certain range of frequencies are loaded into the connector. According to the data, the frequency is transmitted and passed through the connector. The resulting attenuation is used to determine whether a connector is qualified.
As for the problem of transmission delay, most of them are internal reasons of the metal. The resistance value of each metal is different, and the required cross-sectional size is also different. Compared with the requirements of a specific connector, there is a big difference. It is necessary to be more cautious in design and material selection.
The above two considerations are only fundamental. For the type of signal and the increasingly competitive resource requirements, it is necessary to have a comprehensive test of the electrical performance of the connector. Therefore, manufacturers will have a lot of investment in this area, because only such product performance can be accepted by the market.
