According to IEC62368, the classification of power levels and the flame retardant requirements of internal connectors are defined to control the spread of fire. This is a shortcut to fast, efficient and low-cost green electronic products. Figure 4: Prevention of combustion, internal connector, according to IEC62368, the classification of power levels and the flame retardant requirements of internal connectors are defined to prevent ignition.
It is not easy to switch to halogen-free plastics, and its significance is no less than the lead-free revolution in the early electronics industry, but the time left for its implementation is much shorter. To provide the safest flame-retardant electronic equipment, you only need to follow one of the two.
The new regulations allow designers to choose connector specifications that suit their application type. In PS2 and PS3 applications, there are also connectors/sockets that are not potential sources of ignition. In the PS1 circuit, we can directly select UL94-HB material in accordance with the requirements of the IEC standard. If the weight of the shell is greater than 300 grams, the IEC standard recommends that the external connector use at least UL94-V1 flame retardant.
Therefore, SCSI Connector Manufacturers is almost impossible to find a quick solution in a short period of time for some high temperature resistant plastics commonly used in connectors and sockets. According to this proposal, green design can be implemented immediately. The distance between other parts and the illustrated parts will determine whether they need to use flame retardants. Polyvinyl chloride (PVC) is widely used in the cable and wire manufacturing industry to act as a high-efficiency flame retardant
