Safety parameters and technical parameters to be considered when selecting electronic connectors

Electronic equipment, electrical connection is extremely important, electronic connectors can make the equipment and electrical energy connection, realize the operation of the equipment. At present, there are a wide range of types and styles of electronic connectors, it is easy for people to pick the eye. How to choose? In fact, in the selection process, you need to take into account its safety parameters and technical parameters.
Safety parameters (including insulation resistance, voltage, flammability).
1, insulation resistance
The so-called insulation resistance, in fact, is through the terminal connector in the insulation position after applying a certain voltage, so that the insulation position of the surface or internal leakage current presented by the resistance value.
Insulation resistance of the size of the insulating material, temperature, humidity and other influences, and electronic connector manufacturers in the production of the resistance value is often labeled in the standard atmospheric conditions of the index value, so some of the use of the environment, its resistance value may decline.
2, voltage resistance
This is the main contact is not divided into mutual insulation and insulation parts and grounding between, in a certain period of time can withstand than the rated voltage is high, but does not break down the critical voltage.
The size of the withstand voltage and insulator materials, environmental humidity and temperature and contact with the spacing and other factors have a relationship.
3, combustibility
Electronic connectors in the work is often inseparable from the current, the existence of current, there is the potential danger of fire. Therefore, electronic connectors are required to have excellent flame retardant and self-extinguishing.
Mechanical parameters.
1, the number of contact pairs
Need to combine the actual use of requirements to choose the number of contacts, and need to pay attention to the volume of electronic links and the size of the total separation force. Generally speaking, the larger the number of contact pairs, the larger the volume.
2. Mechanical life
This usually refers to the number of times the electronic connector is inserted and removed, generally can reach 500 to 1000 times.
