FIG. 2 is a perspective view showing the appearance of the charging terminal. As shown in FIG. 1 and FIG. 2, the display unit 1 is a panel unit, the operation unit 2 is key-operated, and the battery 4 is a power source. As a function, there is a charging function for the battery 3, a charging terminal 5 for charging the battery 3 is brought into contact with the contact terminal 6 of the charger and the charging terminal 5 from an external power source, and the charging terminal 5 is connected to the mobile phone. The battery 3 is charged through the board 7 in contact with the board 7 inside. An electronic component is mounted on the substrate 7 and a path for supplying electric power to the electronic component is formed. Next, the contact portion (charger side terminal portion, substrate side contact portion) between the charger side and the substrate side of the charging terminal 5 is a contact portion 5-a on the charger side and a contact portion 5-b on the substrate side, respectively. Corresponding to When the charging terminal 5 is formed by bending a sheet metal that is a plate-like conductive member, one side 5-c of the four sides bent like a box lid is used as a contact portion 5-b on the substrate 7 side. It is made to contact the board | substrate 7 as a leaf | plate spring which gave the spring property by bending | flexing. The other three sides of the metal plate bending 5-d (supporting portion) do not have a spring property, bend the metal plate to give rigidity to support external force, and provide the housing 4 with a notch 5-e for mounting. It is provided as an engaging part. Further, a convex step 5-f is provided on the entire outer periphery of the sheet metal flat surface portion 5-a which is a contact on the charger side of the charging terminal 5. This convex step 5-f is formed along the outer periphery of the hole of the housing. The housing 4 is provided with a hook claw 4-a that is an engaging claw for fixing the charging terminal 5, and the notch 5-e on the three sides of the charging terminal 5 is fitted to the hook claw 4-a of the housing 4. Let FIG. 3 is a perspective view showing a state where the charging terminal is attached to the substrate.

  FIG. 4 is a perspective view showing the appearance of the back side of the mobile phone in which the charging terminal is provided on the bottom surface of the housing. FIG. 5 is a cross-sectional view showing a general charging terminal mounting structure. As shown in FIGS. 4 and 5, a mobile phone in which a general charging terminal 5 and a substrate 7 are vertically arranged has a display unit 1 that is a panel unit, an operation unit 2 that operates keys, and a battery 3 that is a power source. Is comprised of a housing 4 in which is stored. The mobile phone shown in FIG. 4 is different from the mobile phone shown in FIG. 1 in which the charging terminal 5 for charging the battery 3 is provided on the bottom surface of the housing 4 and the charging terminal is provided on the back surface of the housing. The configuration is different. When charging the battery 3, the contact terminal 6 of the charger connected to the external power source contacts the charging terminal 5 of the mobile phone and is charged.

Therefore, even if an external force is applied to the contact portion 5-a, the problem that the leaf spring contact portion 5-b is overloaded and plastically deformed can be prevented. That is, since the problem of poor contact of the charging terminal due to plastic deformation can be suppressed, stable charging can be performed on an electronic device such as a mobile phone. Further, by providing a convex shape 5-f on the outer periphery of the sheet metal flat surface portion which is the contact portion 5-a on the charger side of the charging terminal 5, a structure for preventing intrusion of dust or the like into the mobile phone is obtained, and a dustproof effect A structure with Further, since the space between the housing 4 and the substrate 7 can be reduced in size, there is an effect that the thickness of the mobile phone can be reduced.

By adopting the structure described above, out of the four sides to bend the sheet metal of the charging terminal, one side has a spring property for the contact on the substrate side, and external force is applied to the other three sides of the sheet metal bending. Since the structure is such that the leaf spring serving as the contact portion to the substrate is not overloaded such that the leaf spring is plastically deformed. In addition, by providing a convex shape by bending the sheet metal on the outer periphery of the sheet metal flat part that is the contact part on the charger side of the charging terminal, the structure prevents dust and the like from entering the interior of the mobile phone and has a dustproof effect And In addition, since the space between the housing and the substrate can be reduced in size, the thickness of the mobile phone can be reduced.
