How to choose the right electrical connector?

The operation of a connector will affect the function of the whole equipment, and the appropriate electrical connector can bring twice the result with half the effort. So how to choose a suitable electrical connector? Today, Huichengyuan Electronics takes you to understand: 1. Connector type, what to connect, where to use, and so on, these issues should be considered first, which determines the type of industrial connector selected. The location in which the connector is used (indoor, outdoor, corrosive environment, etc.) Will affect whether to enhance the airtightness of the aviation plug or to add a shielding shell to the insulating body. 2、 electrical requirements When selecting electrical connectors, the electrical requirements of the product should be considered. What are the voltage and current requirements of the product, and whether the connector can be used well in such electrical applications, these issues about electrical requirements need to be considered. In addition, we also need to consider other electrical conditions: resistance, allowable resistance change, millivolt drop, maximum current value, maximum voltage value, inrush current value, characteristic impedance, etc. 3、 Environmental Requirements Temperature, humidity, and other environmental conditions are determined by the location of the aircraft connector and should be considered in conjunction with the anticipated environment. And what is the shelf life and information of other relevant storage conditions. Environmental considerations should also include shock and vibration requirements, including those from marine shipping, as well as requirements for production environmental conditions such as welding temperature and welding cycle duration. 4、 mechanical requirements-what volume and footprint are effective for the connector; what are the allowable dimensional tolerances; what are the insertion and withdrawal forces of the terminals; and what is the durability (frequency of mating) of the connector-are all factors to consider when selecting an electrical connector. 5、 specifications must allow for the use of appropriate test specifications in specific applications, including those that are common internationally.
