This paper discusses the application of the plastic flameproof enclosure and its parts.

This paper introduces briefly the demands on and usages of the flameproof enclosure, probes into the methods for re-manufacturing the flameproof enclosure by using the ropey flameproof enclosure as the blank, and analyzes on the benefits of the technique of re-manufacturing the flameproof enclosure.

This article expounds the analysis of causes on the deformation of cylindrical flameproof enclosure,and provides the different welding procedures and measures for the different causes to effectively reduce the deformation.

Against the existing problems in the process of the voltage up-grading for the cylindrical-shaped flame-proof enclosure,on the basis of elasticity mechanics theory,this paper carries out an analysis on the stress distribution of the cylindircal-shaped flameproof enclosure.

This paper systematic analyse the the recommended installation method of explosion-proof enclosure transparent glasses of in existing standards.

The problem of the halt caused by ESD for an IP set top box with plastic enclosure is discussed in detail,and this prob- lem is solved by modifying the PCB plane arrangement and layout.
