What you don’t know about connectors

As connector applications continue to expand, they can be divided into signal and electrical transmission based on two basic functions. In the field of electronic applications, the distinguishing feature of both connectors is that the terminals must have current. In other applications, the voltage provided by the terminal will also be considered very important. Although the same terminal design can be used for both signal and power transmission, in a variety of similar contact applications, many power transmission connectors are designed for the sole purpose of power transmission requirements.

Signal transmission can be divided into two types: analog signal transmission and digital signal transmission.

Whether analog or digital signal connectors, the required functions should mainly protect the integrity of the transmitted voltage pulse, including the waveform and amplitude of the pulse signal. Data signals differ from analog signals in pulse frequency, and their pulse transmission speed determines the maximum frequency of the pulse to be protected.The data pulses travel much faster than some typical analog signals, with some pulses traveling in connectors at speeds approaching billionths of a second. In today’s field of microelectronics, a connector is often thought of as a wire, because the wavelength associated with increasing frequency so rapidly can be compared to the size of the connector.

When connectors or interconnected systems such as cable assemblies are used for high-speed data signal transmission, the corresponding description of connector performance changes. Characteristic impediments of substitute resistors and crosstones in interconnected systems become particularly important.Controlling the characteristic impedance of connectors has become a major awareness trend in controlling crosstalk in cables. Characteristic impedance plays such an important role in connectors because the geometry of resistors is difficult to be completely uniform and the size of connectors is small, so the possibility of crosstalk must be minimized. In a cable, geometry is easily controlled and its characteristic impedance is easily controlled, but the length of the cable may cause potential crosstalk.

In connectors, the control characteristic impedance is built around this reason. In typical open terminal areas, connector impedance (and crosstalk) is achieved by controlling the proper distribution of terminals. For such a signal, the grounding rate is a reflection of this distribution, and the grounding rate decreases.The result, of course, is to reduce the number of terminals available for transmitting signals. The cause and location associated with the signal terminal is a very important consideration. In order to avoid the reduction of grounding terminals, connector systems with integral grounding planes have been developed. The geometry of strips and lines has been described above. The entire grounding plane can be used to transmit signal terminals and improve the density of all signals transmitted by the connector.
