Even while no battery is inserted, a plate covering the charging terminals prevents the stop of charging function by the deformation and destruction of the terminals by external factors and the short circuit which is caused to occur by the contact of the metal material with the charging terminals. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a charger having a function of charging battery packs having different thicknesses.

Conventionally, in a charger provided with a function that enables charging of battery packs having different shapes with a single main body, a regulating member that is movable relative to the thickness of the battery pack is provided on the opposite or lower surface of the charging terminal arrangement surface in the recess. It was.

  However, in the charger described above, the charging terminal is exposed from the recess, and the charging function is stopped due to deformation or destruction of the charging terminal due to an external factor, or a short circuit occurs when a metal part or metal accessory touches the charging terminal. There was a possibility.

In order to solve the above-described conventional problems, a charger according to the present invention includes a circuit board in which various electronic components are incorporated in a case, and includes a charging terminal, a plate, and an elastic member. It is possible to regulate the insertion angle of the battery, and to move up and down according to the thickness of the battery inserted into the charging terminal portion of the charger. In addition, even when no battery is inserted, the charging terminal is equipped with a plate so that the terminal is deformed due to external factors, the charging function is stopped due to destruction, or a short circuit occurs when a metal object touches the charging terminal. This is a charger characterized by preventing the above.
By using the charger of the present invention, when the battery pack is inserted into the pocket, the tip of the battery pack comes into contact with the tip of the movable collar provided at the upper portion of the charging terminal, and the plate according to the thickness of the battery pack When the battery pack is completely inserted, the bottom surface of the plate holds the upper portion of the battery pack so that the battery packs having different thicknesses can be held and regulated.

  In addition, when the battery pack is not inserted (when the battery pocket is empty), when a portable object such as a metal accessory is dropped on the charger by the plate provided on the top of the charging terminal, It is possible to prevent the charging function from being stopped due to deformation or destruction of the charging terminal caused by the hand, or a short circuit that occurs when the dropped metal accessory or the like electrically connects the charging terminals.

  According to the present invention, in the battery charger that is attached to the battery pack charger main body and charges the battery pack by bringing a battery terminal provided in the battery pack into contact with a charging terminal provided in the charger main body. The battery pack is compatible with charging of multiple types of battery packs and includes a plate for regulating the position of the battery pack according to the thickness of the battery pack to be mounted. it can.

In addition, since the regulating member is provided on the upper part of the charging terminal, the charging terminal is protected, that is, the charging terminal is deformed due to an external factor, the charging function is stopped due to destruction, or the metal part touches the charging terminal. A short circuit can be prevented.

  The best mode for carrying out the present invention will be described below with reference to the drawings. In each figure, the same number is given to the same component.

  FIG. 1 is a perspective view of the charger 1. The charger 1 is packaged by an upper case (exterior body) 2, a lower case (exterior body) 3 and a cover (exterior body) 4, and the position of the plate 5 is regulated by the upper case 2 and the cover 4. It is configured so that a plurality of types of battery packs can be mounted.

  2 and 3 are a top view (FIG. 2) and a front view (FIG. 3) of the charger 1. Charging starts when the battery terminal of the battery pack contacts the charging terminal 6 of the charger 1.

FIG. 4 is a cross-sectional view of the charger 1. The position of the plate 5 is regulated by the protrusion 12 extending from the upper case 2 and the cover 4. Further, a spring member 7 is attached to the protrusion 12 so that the plate 5 can move in the vertical direction according to the thickness of the battery pack. At this time, since the plate 5 is provided on the charging terminal 6, the charging terminal 6 is protected, that is, the charging terminal 6 is deformed due to an external factor, the charging function is stopped due to destruction, and a metal part is attached to the charging terminal 6. A short circuit generated by touching can be prevented.
FIG. 5 is a cross-sectional view of the charger 1 when the charging terminal 6 is disposed on the bottom surface of the battery pocket 11. This configuration is used when charging a battery pack having terminals on the bottom surface.

  FIG. 6 is a cross-sectional view of the charger 1 when the small battery pack 9 is mounted. The vertical position regulation of the mounted battery pack is performed on the bottom surface of the plate 5 and the top surface of the upper case 2.

  FIG. 7 is a cross-sectional view of the charger 1 when a large battery pack is mounted. When the large battery pack 10 is mounted, the tip of the large battery pack 10 hits the tip of the plate 5, and further pushing the large battery pack 10 pushes the plate 5 up in the vertical direction. As a result, the position of the bottom surface of the plate 5 is raised, and the position of the large battery pack 10 can be regulated.

  FIG. 8 is a top view of the charger 1 provided with the movable rib 13. The movable rib 13 can be moved according to the width of the battery. For example, as shown in FIG. 9, even when the small battery pack 9 whose width is smaller than the width of the battery pocket 11 is inserted, the movable rib 13 is small. The pack 9 can be positioned in the width direction and charged reliably. Further, even when the large battery pack 10 having the same width as the battery pocket 11 is charged as shown in FIG. 10, the movable rib 13 is pushed laterally when the large battery pack 10 is inserted. The large battery pack 10 is stored in the battery pocket 11 and can be charged reliably.

  As described above, according to the present invention, it is possible to charge the battery pack by reliably regulating the position of a plurality of types of battery packs, and also has a protection function from external factors of the charging terminal. There is no waste of preparing a dedicated charger for each thickness of the pack, and the user can be provided with convenience when using multiple types of battery packs.
