る。2. Description of the Related Art In a charging terminal structure for a cordless telephone of this type, a charging terminal on the master side, which is connected to a power source built in the master, is formed on the surface of the charging part of the master so as to be exposed outside. Corresponding to this, on the bottom surface of the child device, a child device side charging terminal connected to a battery built in the child device is exposed and formed. The base unit side charging terminal is integrally attached to a leaf spring having a spring property, and is installed so that a spring force is applied in the contact direction with the handset unit. Both the main unit side charging terminal and the leaf spring are made of a conductive member, and are connected to a power source from one end of the leaf spring by a lead wire or the like.

なくなるという問題があった。By the way, in such a structure in which both charging terminals are exposed to the outer surface, since the hand of the handset is easily touched by a human hand, an insulating film is easily formed on the surface of the charging terminal due to adhesion of oil and dust from the hand. Also, on the parent device side, the adhesion of dust easily causes an insulating film to be formed on the charging terminal surface. Such an insulating film is difficult to be removed by the contact force of the charging terminals, gradually accumulates and hinders stable contact between the charging terminals, and becomes an insulator at the contact portion of the charging terminals, which makes charging impossible. there were.

いる。In order to solve such a problem, for example, in Japanese Utility Model Laid-Open No. 3-120152, the charging terminal on the base unit side has a conical shape so that dust is hard to collect, while the window for exposing the charging terminal is provided on the bottom surface of the handset unit. Along with the formation of the charging terminal, the charging terminal on the slave side is slidably provided at an inner position deviated from the window for exposing the charging terminal, and the charging terminal on the slave side is slid by the guide slope formed on the master side at the time of installation. Technology is proposed.
