I. What are the requirements and environments for the use of industrial connectors?

1, environmental requirements: temperature, humidity and other environmental conditions are determined by the location of the electrical connector, and therefore should consider the location and the expected environment. And other relevant storage conditions of the applicable period and what is the information. The description of the environment should also cover the requirements for shock and vibration, including from the maritime requirements, as well as production environmental conditions. For example, the soldering temperature and the duration of the soldering cycle requirements. Connector manufacturers say that in the connector to lead the convergence of the continuous current around the higher temperature is generated in the area.

2, electrical requirements: in the selection of electrical connectors, to consider the electrical requirements of the product. The product has what kind of voltage and current requirements, the connector can be well applied to such electrical, these electrical requirements on the issue are to be considered. In addition, also need to consider some of the electrical conditions: resistance, allowable resistance variation, voltage drop, high current values, higher voltage values, inrush current values, characteristic impedance, (voltage VSWR), insertion and removal loss masking efficiency.

3, mechanical performance requirements: for the connector, what kind of volume and coverage area is effective allowable size tolerance is how much; terminal insertion and extraction force is how much; connector durability (insertion and extraction with the frequency) how? These factors are in the selection of electrical connectors to consider. Such as: for printed circuit boards, to determine the tolerance of the board is very important, it is the critical value of the card edge connector, as well as the feasibility of reaching the critical. For low-power circuits, plating and backing materials must be specified and signaling standards and environmental ratings.
