Charger having heat insulating structure

A charger comprising:

• a case having one side at which an opening is formed and the other side to which a terminal portion is coupled;
• a printed circuit board having a front surface and a rear surface on which electronic components are mounted, respectively, and inserted into the case through the opening of the case;
• a heat insulating member disposed inside the case and formed to cover the electronic components mounted on the rear surface of the printed circuit board to block heat generated from the electronic components of the printed circuit board from being transferred to an entire surface of the case;
• a cover closing the opening of the case;
• and
• an additional heat insulating member disposed inside the case and covering the electronic components mounted on the front surface of the printed circuit board,
• wherein the additional heat insulating member has a shorter length than the heat insulating member, and
• wherein both of the heat insulating member and the additional heat insulating member include:
• a central portion;
• and
• end portions positioned at both sides of the central portion with the central portion interposed therebetween,
• the central portion being spaced farther apart from the printed circuit board than the end portions.
