PROBLEM TO BE SOLVED: To provide a portable communication equipment of explosion proof type in which an event of a load by a power limit is concentrated onto a battery pack is avoided so as to realize miniaturization and light weight of the power limit element and the battery pack and an optimum power limit is realized to various circuit sections built in the portable communication equipment. SOLUTION: A battery pack side power limit element 19 is provided in a power supply line 18 at the side of a battery pack 3 and plural main body side power limit elements 21-24 are provided in parallel in a power supply line 20 at the side of a portable communication equipment main body 2. Then the load of power limit is distributed in the power supply paths from the battery pack 3 to the portable communication equipment side 2, and miniaturization and light weight are attained for the battery pack side power limit element 19 and the battery pack 3 and a proper power limit is respectively applied to various circuit sections 5-8 built in the portable communication equipment main body 2. |
