Description

  The present invention relates to a toy dry battery box.

Conventionally, dry batteries used for electric devices and electric toys include manganese dry batteries and alkaline dry batteries. Manganese batteries use manganese dioxide as the positive electrode and depolarizer, zinc as the negative electrode, and zinc chloride as the electrolyte. Zinc chloride is packed in a zinc container in the form of a black paste mixed with manganese dioxide. The container is covered with a tube called a metal jacket so as not to leak.
Alkaline batteries use zinc powder for the negative electrode and manganese dioxide for the positive electrode. Since the container is configured as a positive electrode, the portion near the center of the bottom portion becomes the negative electrode, and the synthetic resin film label, which is an insulating material, is wrapped and adhered to the outer peripheral surface and the portion near the outer peripheral surface of the container. At the bottom surface of the dry battery, the positive electrode and the negative electrode face each other with an insulating material at a slight interval. Therefore, even if the alkaline dry battery is covered with the synthetic resin film label of the insulating material, the synthetic resin film label is easily damaged by the tip of the metal material. For example, as shown in FIG. The elastic contact member 43 composed of the negative electrode coil spring is in contact with the negative electrode of the alkaline battery 44, that is, the central portion 45 of the alkaline battery, and a part 43 a of the elastic contact member 43 is on the external surface of the alkaline battery 44. When the cover 46 is forcibly closed in a state corresponding to the side, the elastic contact member 43 breaks the synthetic resin film label 47 and contacts the positive electrode of the container outer peripheral surface 44a of the alkaline dry battery 44. Will be short-circuited. Therefore, the alkaline battery 44 generates heat, and the electrical equipment and the electric toy become dangerous.
Moreover, when accommodating a dry cell in the dry cell accommodating part of an electric equipment and an electric toy, it is necessary to connect each polarity correctly regardless of a single piece or plural pieces.

The part 3b1 is provided with a first recessed hole 3a11 and a second recessed hole 3b11 into which the protruding part 2a1 of the positive electrode 2a of the dry battery 2 is fitted, and the first recessed hole 3a11 and the second recessed hole 3b11 face each other. Then, the first fixed positive electrode supply electrode plate 5b and the second fixed positive electrode supply electrode plate 5b are opposed to each other, with which the front end surface 2a11 of the protruding portion 2a1 of the positive electrode 2a of the dry battery 2 collides and contacts.

  In the first compartment 3a and the second compartment 3b of the housing part 3, the first negative-side inner wall plate part 3a2 and the second negative-side inner wall plate part 3b2 provided to face the bottom surface part 2b1 closer to the center, which is the other negative electrode 2b of the dry battery 2. The negative inner wall plate portion 3b2 is provided with a first bearing hole 3a21 and a second bearing hole 3b21. The first bearing hole 3a21 and the second bearing hole 3b21 have a bottom surface portion 2b1 near the center of the negative electrode 2b of the dry battery 2. The first movable negative electrode supply electrode 6a and the second movable negative electrode supply electrode 6b that are connected to each other are biased by the first coil spring 7a and the second coil spring 7b, respectively, and are slidable in the axial compression direction and the expansion direction. To be provided respectively.

  The first movable negative electrode supply electrode 6a and the second movable negative electrode supply electrode 6b have outer peripheral portions 6a2 and 6b2 parallel to each other in a semispherical shape in which the top portions 6a1 and 6b1 are curved by pressing a conductive metal plate. Base edge portions 6a3 and 6b3 are respectively formed on the cylindrical surfaces on the flange surfaces that bend outward.

  The outer peripheral portion 6a2 of the first movable negative electrode feed electrode 6a is loosely fitted in the first bearing hole 3a21, and the outer peripheral portion 6b2 of the second movable negative electrode feed electrode 6b is loosely fitted in the second bearing hole 3b21. Since one end of the first coil spring 7a and one end of the second coil spring 7b are fitted and connected to be biased, it is moved in the expansion direction, and the flange surface of the base edge portion 6a3 of the first movable negative electrode supply electrode 6a is On the opposite surface of the first negative electrode side inner wall plate portion 3a2, the flange surface of the base edge portion 6b3 of the second movable negative electrode feeder 6b is connected to the opposite surface of the second negative electrode side inner wall plate portion 3b2, and the top portion 6a1 is The first compartment is held in the projecting state by 3a and the top portion 6b1 is kept in the second compartment 3b.

  When the dry cell 2 is accommodated in the first compartment 3a, for example, when the projecting portion 2a1 of the positive electrode 2a of the dry cell 2 faces the first positive electrode side inner wall plate 3a1 of the first compartment 3a, the projecting portion 2a1 is 1 is fitted into the recessed hole 3a11, and the tip end surface 2a11 of the protrusion 2a1 can be brought into contact with the first fixed positive electrode supply electrode plate 5a. Similarly, when the dry battery 2 is accommodated in the second compartment 3b, when the protruding portion 2a1 of the positive electrode 2a of the dry battery 2 faces the second positive electrode side inner wall plate 3b1 of the second compartment 3b, the protruding portion 2a1 is formed. It can fit in the 2nd recessed fitting hole 3b11, and can contact the front end surface 2a11 of the protrusion part 2a1 with the 2nd fixed positive electrode feed electrode board 5b.

Next, for example, when the bottom surface portion 2b1 near the center of the negative electrode 2b of the dry battery 2 is opposed to the first positive electrode side inner wall plate portion 3a1 of the first compartment 3a, the bottom surface portion 2b1 near the center of the negative electrode 2b has the first concave portion. Since the outer diameter is larger than the fitting hole 3a11, it cannot be fitted into the first concave fitting hole 3a11, and the bottom surface portion 2b1 closer to the center of the negative electrode 2b is in contact with the opposing first fixed positive electrode supply electrode plate 5a. I can't. Similarly, when the dry battery 2 is accommodated in the second compartment 3b, the bottom surface portion 2b1 near the center of the negative electrode 2b cannot be fitted into the second recessed fitting hole 3b11, and the bottom surface portion 2b1 near the center of the negative electrode 2b is opposed. The first fixed positive electrode electrode plate 5a cannot be contacted.
Moreover, the positive electrode 2a of the dry cell 2 can always be correctly connected to the first fixed positive electrode supply electrode plate 5a of the first compartment 3a and the second fixed positive electrode supply electrode plate 5b of the second compartment 3b.

  When the dry battery 2 is accommodated in the first compartment 3a, when the protrusion 2a1 of the positive electrode 2a of the dry battery 2 is opposed to the first negative-side inner wall plate 3a2, the protrusion 2a1 of the first movable negative electrode supply electrode 6a The top 6a1 can be brought into contact, and the protrusion 2a1 of the positive electrode 2a of the dry cell 2 can be accommodated in the first compartment 3a by being pushed in. The bottom surface portion 2b1 near the center of the negative electrode 2b on the opposite side of the dry cell 2 does not protrude from the first fixed positive electrode supply electrode plate 5a to the first positive electrode side inner wall plate portion 3a1, and thus the negative electrode 2b of the dry cell 2 can be easily formed. The side can be accommodated in the first compartment 3a. However, as described above, even if the positive electrode 2a side of the dry battery 2 is connected to the first movable negative electrode supply electrode 6a, the bottom surface portion 2b1 near the center of the negative electrode 2b of the dry battery 2 is in contact with the first fixed positive electrode supply electrode plate 5a. The power supply circuit cannot be established because it cannot be performed.

  Next, the negative electrode 2b side of the dry battery 2 is first inserted into the first compartment 3a facing the first positive electrode side inner wall plate 3a1, and then the protruding part 2a1 side of the positive electrode 2a of the dry battery 2 is connected to the first negative electrode side. When the protruding portion 2a1 of the positive electrode 2a of the dry battery 2 faces the first movable negative electrode feed electrode 6a when facing the inner wall plate portion 3a2 and inserted into the first compartment 3a, Since the top portion 6a1 of the movable negative electrode supply electrode 6a is formed on a curved surface, the lateral pressing force of the protruding portion 2a1 of the positive electrode 2a of the dry battery 2 is converted into an axial moving force to cause the first coil spring 7a to move. The first movable negative electrode supply electrode 6a is compressed and moved into the first negative electrode side inner wall plate portion 3a2, and the repulsive force of the first coil spring 7a can be received and accommodated in the dry cell 2. The elastic member is not pressed from the lateral direction. Therefore, even if the dry battery 2 is an alkaline dry battery, the outer synthetic resin label is not damaged.

  Further, the protruding portion 2a1 side of the positive electrode 2a of the dry battery 2 is first inserted into the first compartment 3a facing the first positive electrode side inner wall plate portion 3a1, and then the negative electrode 2b side of the dry cell 2 is inserted into the first negative electrode side inner wall. Even when the bottom surface portion 2b1 near the center of the negative electrode 2b of the dry battery 2 faces the plate portion 3a2 and is inserted into the first compartment 3a so as to face the first movable negative electrode feeder 6a, the first Since the top portion 6a1 of the movable negative electrode supply electrode 6a is formed on a curved surface as described above, the lateral pressing force of the bottom surface portion 2b1 closer to the center of the negative electrode 2b of the dry battery 2 is the first movable negative electrode supply electrode 6a. The first coiled spring 7a is compressed to move the first movable negative electrode feeder 6a into the first negative electrode side inner wall plate 3a2, and the repulsive force of the first coiled spring 7a is converted into an axial moving force. The dry battery 2 is In dry batteries, the container is configured as a positive electrode, and the outer peripheral edge of the bottom surface portion under the synthetic resin label is a positive electrode. Therefore, it can be easily synthesized when pressed against a conventional coil spring type elastic member from the side. Although the resin label is damaged, the top 6a1 of the first movable negative electrode feeder 6a is curved and comes in contact with a wide area, so that the contact pressure is not lowered and is not damaged, and is closer to the center of the negative electrode 2b of the dry battery 2. The bottom surface portion 2b1 is always in proper contact with the top portion 6a1 of the first movable negative electrode supply electrode 6a, and even if the dry battery 2 is an alkaline battery, it is not short-circuited.

  The embodiment in which the dry battery 2 is accommodated in the first compartment 3a operates similarly in the embodiment in which the dry battery 2 is accommodated in the second compartment 3b.
