[0019] Working principle: When in use, by placing the wires in the wire slot 13, and then through the insulator 12, the heat shrink tube 10 and the mother mica 9, the wires have the effect of insulation and fire resistance, and then the flame retardant partition 8 realizes the flame retardant effect.
