Spark-free explosion-proof electrical connector connection

Explosion-proof electrical connectors from the appearance of the general is round, divided into fixed and mobile. Corrosive use of the environment generally choose stainless steel materials, plus hard plating treatment, use in harsh environments is not a big problem. Connection method is generally a spiral bayonet connection, current, shape and volume, is an iron die-casting products, heavy quality, can withstand the fall, in the past, deep wells, mining coal mine car used especially. With the development of science and technology, the miniaturization of detection instruments, field and field signal transmission through the Internet, the explosion-proof plug used above the corresponding small, but the role is not weaker than before, but also bayonet connection, convenient and reliable. Here to introduce the outdoor work encountered this connection can be? After practical experiments, the threaded connection is relatively better, although not as fast as the bayonet connection, but in special places to prevent sand, gas, liquid, sparks penetration is stronger, using fine threads, taper connection, the end of the double sealing compression ring, and when appropriate, but also explosion-proof mastic plug, the amount of energy to eliminate the possibility of explosion.
