What other industry knowledge of waterproof connector do you not know?

Waterproof connectors have been used more and more widely. When it comes to waterproof connectors, people in the industry basically know it, but many people who are still relatively shallow in terms of aspects do not understand it enough. Today, plug in world network will tell you about the application of waterproof connectors. I hope this article can help some people in need.

They can be divided into signal transmission and electrical transmission according to their two basic functions. In the field of electronic applications, the remarkable feature of these two types of connectors is that their terminals must have current. In other applications, the voltage provided by the terminals will also be considered as a very important object. Although the design of the same terminal can be used as two functions of signal and power transmission at the same time, in the application of many similar contact modes, Many electrical transmission waterproof connectors only take the need of power transmission as the only purpose in terminal design.

Among them, signal transmission can be divided into two categories: analog signal transmission and digital signal transmission.

Regardless of the analog or digital signal connector, its required function shall mainly be able to protect the integrity of the transmitted voltage pulse signal, which shall include the waveform and amplitude of the pulse signal. The pulse frequency of data signal is different from that of simulation signal. Its pulse transmission speed determines the maximum frequency of the protected pulse. The transmission speed of data pulse is much faster than that of some typical simulation signals. The transmission speed of some pulses in the connector has been close to the range of one hundred billionth of a second. In today's microelectronic technology field, The connector is usually treated as a wire because the wavelength associated with the frequency growing so fast can match the size of the connector.

When a connector or an interconnection system such as a cable assembly is used in high-speed data signal transmission, the corresponding description of the performance of the connector changes. Instead of the characteristic impedance of the resistance and crosstalk in the interconnected system become particularly important. Controlling the characteristic impedance of the connector has become a major trend of consciousness, and crosstalk is controlled in the cable. The reason why characteristic impedance plays such an important role in waterproof connectors is that the geometric shape of resistance is difficult to be completely unified, and the connector size is very small, so the possibility of crosstalk must be minimized. In the cable, it is easy to control the geometry and its characteristic impedance, but the length of the cable may cause potential crosstalk.

In the connector, the control of characteristic impedance is carried out around this reason. In the typical open terminal area, the connector impedance (and crosstalk) is achieved by controlling the terminals in a reasonable distribution. For such signals, the grounding ratio is a reflection of this distribution, and the grounding ratio is reduced. The number of terminals that can be used to transmit signals will certainly be reduced accordingly. Therefore, in order to prevent the reduction of grounding terminals, connector systems with an overall grounding plane are widely used. The geometry of micro strips and strips has been described earlier. The overall grounding plane allows the use of signal transmission terminals and can improve the density of all transmitted signals of the connector.
