By introducing the device introduced into the lamp cable, from installation to use the entire process, if there is likely to be tension proof lighting lights, the introduction of the compression nut on the device or close to the introduction of the device inside the lamp to increase anti-pull off the cable clips, to prevent power transmission to prevent the cables from the terminals and possible brand mobile explosion-proof lighting, bad or failed to prevent an electrical connection. Lighting in the design may need to provide a means to introduce more proof lighting, convenient installation requirements of different users. At the factory, should be introduced in all of the devices are installed to block parts, structural block piece must fit the type of protection. Or, install only one entries, the rest (after the introduction of device removal) hole with a suitable type of protection bulkhead instead. Thus, the excess will not forget to block the introduction of device failure caused by flameproof enclosure.
