In the case of outdoor use, rainwater may enter the case through the insertion hole of the cylindrical body, and this may adhere to the circuit board and cause a short circuit.To prevent this, conventionally, the circuit board Measures such as forming a resin shield layer on the surface have been taken. However, such measures have the problems of increasing costs and increasing the number of assembling steps. Therefore, as a waterproof structure that solves this problem, for example, a conventional Japanese Utility Model Laid-Open No. 4-1311861 has been proposed.
There is a waterproof structure as disclosed in Japanese Patent Publication No. According to this, the upper end of the drain case on the lower case side is fitted to the outer periphery of the lower end of the insertion port on the upper case side, and the charging terminal is sandwiched and fixed between the two. Since the battery insertion part formed by the insertion opening of the lower case and the drain case on the lower case side and the circuit board side are shielded, reliable waterproofing could be performed without forming a shield layer on the surface of the circuit board. .
