The operation of a connector affects the function of the entire device, and a suitable electrical connector can achieve a multiplier effect. So how do you choose a suitable electrical connector? We can consider the following related aspects:
1, Connector type
What to connect, where to use, etc. These issues are first considered, which determines the type of industrial connector chosen. The location where the connector is used (indoor, outdoor, corrosive environment, etc.) can affect whether the air plug is to be sealed or shielded from the insulative housing. The type of connector determines which termination is used and how many conductive terminals to arrange. Of course, this also involves some reference to the terminal technology.

2, Electrical requirements
When selecting an electrical connector, consider the electrical requirements of the product. What kind of voltage and current requirements are there for the product, and whether the connector can be used well in such electrical properties, these questions 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, VSWR (voltage standing wave ratio), plug Pulling loss and EMI shielding efficiency.

3. Environmental requirements
Temperature, humidity, and other environmental conditions are determined by the location of the electrical connector, so the location and expected environment should be considered. And the shelf life of other relevant storage conditions and what the information is. Environmental and environmental requirements should also be covered, including requirements for shipping and environmental conditions such as welding temperature and duration of the welding cycle. The connector manufacturer stated that around the confluent continuous current guided by the connector is the area where the highest temperature is generated.

4, Mechanical performance requirements
What size and footprint is effective for the connector; what are the allowable dimensional tolerances; what is the insertion and pull-out force of the terminals; and how durable the connector is (frequency of insertion and removal) These factors are all considered when choosing an electrical connector. For example, for printed circuit boards, it is important to determine the tolerances of the board. It is the critical value of the card edge connection and the feasibility of reaching criticality. For low power circuits, the plating and underlying materials must be specified to be consistent with the signal standard and environmental rating.

5, Specifications
Connector manufacturers can use approximately 25 test mechanisms (specified specifications) as a source of all or part of their connector's test specifications. Consideration must be given to the application of appropriate test specifications for specific application scenarios, including international
