The depth dimension d ₆ of these concave steps 46 is equal to or greater than the thickness dimension t ₆ of the fixing claw 48 described later of the battery contact piece 43. Further, the distance L ₅ from the inner end of the concave step portion 46 to the fixing hole 45 is equal to or larger than the dimension L ₆ of the bent portion 48A of the fixing claw 48. Further, an inclined surface 47 is formed on the upper surface of the bottom portion 44 so as to extend inward of each of the fixing holes 45 adjacent to the fixing holes 45. These inclined surfaces 47 are inclined so as to be outward toward the lower side. Then, the bent portion 48A of the fixing claw 48 can come into contact with each of the inclined surfaces 47.

The battery contact piece 43 includes a substrate portion 16, a fixing claw 48, and an upright portion 18. The substrate portion 16 comes into contact with an electrode of either a dry battery or a secondary battery. Further, the fixing claw 48 is for fixing the battery contact piece 43 to the lid main body 42. Further, when the battery lid 41 is attached to the main body 3, the upright portion 18 makes electrical contact with a contact piece (not shown) provided on the main body 3. The substrate portion 16 is formed in a substantially circular shape, and a through hole 19 is formed in the central portion thereof. Further, three fixing claws 48 are provided on the outer peripheral portion of the substrate portion 16 in an annular shape and at equal intervals, corresponding to the fixing holes 45. Then, each of the fixing claws 48 is bent downward at a right angle to the substrate portion 16. Further, the tip portion of the fixed claw 48 is a bent portion 48A. The bent portion 48A is bent at a right angle and inward. As described above, the dimension L ₆ of the bent portion 48A is the distance L ₅ or less from the inner end of each concave step portion 46 to the fixing hole 45. On the other hand, the upright portion 18 extends laterally from the outer circumference of the substrate portion 16 and then is bent upward at a right angle. In the state of being attached to the lid main body 42, the battery contact piece 43 is inserted into the fixing hole 45 to which the fixing claw 48 corresponds, and the bent portion 48A on the tip side thereof is the concave step portion. It is hung on 46. At this time, as described above, the depth dimension d ₆ of the concave step portion 46 is equal to or greater than the thickness dimension t ₆ of the fixing claw 48, and the distance from the inner end of the concave step portion 46 to the fixing hole 34. Since L ₅ is equal to or larger than the dimension L ₆ of the bent portion 48A of the fixed claw 48, the bent portion 17A fits within the concave step portion 46. Further, the upright portion 18 is located near the inner surface of the side surface portion 10 of the lid main body 42.

The covering member 8 has a flat surface, and has a substrate portion 20 as a circular flat surface portion having waterproof properties and made of a synthetic resin, and a waterproof adhesive layer 21 formed on the upper surface of the substrate portion 20. Through holes 22 and 23 are formed in the central portions of the substrate portion 20 and the waterproof adhesive layer 21, respectively. Further, the waterproof film 9 is made of a material having breathability, moisture permeability and waterproofness. Then, the waterproof film 9 is attached to the central portion of the inner surface of the bottom portion 44 of the lid main body 42 so as to close the through hole 13. The waterproof film 9 discharges gas that may be generated when an abnormality occurs in the dry battery or the secondary battery to the outside of the electric device 1, and is in a liquid state in the electric device 1 from the outside. It is provided to prevent water from entering. Therefore, if the electrical device 1 does not need to be waterproof, the waterproof film 9 is not always necessary.

The assembly process of the battery lid 41 will be described. First, in the first step of assembly, the waterproof film 9 is attached to the center of the inner surface of the bottom portion 44 of the lid body 42 so as to close the through hole 13. Then, the battery contact piece 43 is covered from above the waterproof film 9. At this time, the bent portion 48A of the fixing claw 48 of the battery contact piece 43 comes into contact with the corresponding inclined surface 47.

Next, in the second step of assembly, the battery contact piece 43 is pushed downward. When the battery contact piece 43 is pushed downward in this way, each of the fixing claws 48 is elastically deformed so as to widen the distance between them along the inclined surface 47, and then descends through the fixing hole 45. .. Then, when the bent portion 48A of the fixed claw 48 reaches the concave step portion 46, the distance between the fixed claws 48 that have been elastically deformed is restored. As a result, the bent portion 48A of the fixing claw 48 is hooked on the concave step portion 46 and is prevented from coming off. That is, the battery contact piece 43 is fixed to the lid body 42. At this time, as described above, the depth dimension d ₅ of the concave step portion 46 is equal to or greater than the thickness dimension t ₆ of the fixing claw 48, and the distance from the inner end of the concave step portion 46 to the fixing hole 45. Since L ₅ is equal to or larger than the dimension L ₆ of the bent portion 48A of the fixed claw 48, the bent portion 48A fits within the concave step portion 46. Further, the through hole 19 of the substrate portion 16 of the battery contact piece 43 communicates with the through hole 13 of the bottom portion 44 of the lid main body 42 via the waterproof film 9. Then, as described above, the upright portion 18 is located near the inner surface of the side surface portion 10 of the lid main body 32.

In this way, the battery lid 41 is inserted into the fixing hole 34 of the bottom portion 33 of the lid main body 42 with the tip portion of the fixing claw 48 bent, so that the battery contact piece 43 becomes the lid main body. Since it is fixed to 42, the battery contact piece 43 is easily and surely fixed to the lid body 42. Further, since the bent portion 48A of the bent fixing claw 48, the fixing hole 45, and the concave step portion 46 are covered by the covering member 8, the appearance can be improved. Further, since the depth dimension d ₅ of the concave step portion 46 is equal to or larger than the thickness dimension t ₆ of the fixing claw 48, when the covering member 8 is attached to the bottom portion 44 of the lid body 42, it is bent. The portion of the portion 48A does not bulge. Further, since the outer surface of the bottom portion 44 of the lid body 42 is a flat surface (that is, an expandable surface) and the covering member 8 is a flat surface, when the covering member 8 is attached to the outer surface of the bottom portion 44, the covering member 8 is described. Since the covering member 8 is attached without expanding and contracting, the covering member 8 can be reliably attached to the outer surface of the bottom surface 44 without any gap.

Since the covering member 8 is attached to the bottom portion 44 by the waterproof adhesive layer 21, even if water is splashed on the electric device 1, water is introduced into the electric device 1 from between the bottom portion 44 and the substrate portion 20. Does not invade. On the other hand, the through holes 22 and 23 of the covering member 8 communicate with the through holes 13 of the lid main body 42. Therefore, when the electric device 1 is splashed with water, the water enters the through holes 13 through the through holes 22 and 23. However, as described above, since the waterproof film 9 is attached to the central portion of the inner surface of the bottom portion 44 so as to close the through hole 13, water does not enter the electric device 1. Further, gas may be generated when an abnormality occurs in the dry battery or the secondary battery, and this gas passes through the through hole 19 of the battery contact piece 43 and passes through the waterproof film 9, and the lid main body. It is discharged to the outside of the electric device 1 through the through hole 13 of 41 and the through holes 23 and 22 of the covering member 8.

By doing so, the covering member 8 can be surely adhered to the bottom portion 44 without a gap.

Further, in the present invention, the concave step portion 46 is provided on the bottom portion 44 adjacent to the fixing hole 45, and the depth dimension d ₆ of the concave step portion 46 is equal to or larger than the thickness dimension t ₆ of the fixing claw 48. Therefore, when the covering member 8 is attached to the bottom portion 44, the portion of the fixing claw 48 is prevented from bulging, and the appearance can be improved.

Further, in the present invention, since the covering member 8 is waterproof because it is composed of the substrate portion 20 as a flat surface portion having waterproofness and the waterproof adhesive layer 21, the battery lid 41 of the waterproof device can be easily configured. Can be done.

That is, the lid body 52 has a tubular side surface portion 10 and a bottom portion 55. In the present embodiment, the outer surface of the side surface portion 10 has a regular octagonal tubular shape, and the inner surface has a cylindrical shape. Then, on the inner surface of the side surface portion 10, a protrusion 12 for connecting the battery lid 51 to the main body 3 of the electric device 1 by bayonet is formed. On the other hand, the outer surface of the bottom portion 55 is flat and has a step with the lower end 10A of the side surface portion 10. The depth dimension d ₇ of the step of the bottom portion 55 with respect to the lower end 10 A of the side surface portion 10 is the thickness dimension t ₇ or more of the covering member 54. Then, in the bottom portion 55, three fixing holes 56 are formed in an annular shape and at equal intervals through the bottom portion 55. Further, a concave step portion 57 is formed on the lower surface of the bottom portion 55 so as to extend inward of the fixing holes 56 adjacent to the fixing holes 56. The depth dimension d ₈ of these concave steps 57 is equal to or greater than the thickness dimension t ₈ of the fixing claw 17 of the battery contact piece 53. Further, the distance L ₇ from the inner end of the concave step portion 57 to the fixing hole 56 is equal to or larger than the dimension L ₈ of the bent portion 17A of the fixing claw 17.

The battery contact piece 53 includes a substrate portion 58, a fixing claw 17, and an upright portion 18. The substrate portion 58 comes into contact with an electrode of either a dry battery or a secondary battery. Further, the fixing claw 17 is for fixing the battery contact piece 53 to the lid main body 52. Further, when the battery lid 51 is attached to the main body 3, the upright portion 18 makes electrical contact with a contact piece (not shown) provided on the main body 3. The substrate portion 58 is formed in a substantially circular shape. Further, three fixing claws 17 are provided on the outer peripheral portion of the substrate portion 58 in an annular shape and at equal intervals, corresponding to the fixing holes 56. Then, each of the fixing claws 17 is bent downward at a right angle to the substrate portion 58 in a state before being attached to the lid main body 52. On the other hand, the upright portion 18 extends laterally from the outer circumference of the substrate portion 58 and then is bent upward at a right angle. In the state of being attached to the lid main body 52, the battery contact piece 53 is inserted into the fixing hole 56 corresponding to the fixing claw 17, and the bent portion 17A on the tip side thereof is bent inward. .. At this time, as described above, the depth dimension d ₈ of the concave step portion 57 is equal to or greater than the thickness dimension t ₈ of the fixing claw 17, and the distance from the inner end of the concave step portion 57 to the fixing hole 56. Since L ₇ is equal to or larger than the dimension L ₈ of the bent portion 17A of the fixed claw 17, the bent portion 17A fits within the concave step portion 57. Further, the upright portion 18 is located near the inner surface of the side surface portion 10 of the lid main body 52.

The covering member 54 has a disk shape, and has a circular substrate portion 59 having waterproof properties and made of a synthetic resin, and an annular waterproof packing 60 provided on the outer periphery of the substrate portion 59.

Next, a fifth embodiment of the present invention will be described with reference to FIG. In this embodiment as well, only the battery lid 61 will be described. Further, in the present embodiment, the first step and the second step of the assembly are common to the fourth embodiment, and thus the description thereof will be omitted. The battery lid 61 includes a lid main body 52, a battery contact piece 53, and a covering member 62. In this embodiment, the waterproof ventilation structure is provided in addition to the battery lid 61. The lid body 52 is formed of a synthetic resin into a bottomed tubular shape. That is, the lid body 52 has a tubular side surface portion 10 and a bottom portion 55. In the present embodiment, the outer surface of the side surface portion 10 has a regular octagonal tubular shape, and the inner surface has a cylindrical shape. Then, on the inner surface of the side surface portion 10, a protrusion 12 for connecting the battery lid 61 to the main body 3 of the electric device 1 by bayonet is formed. On the other hand, the outer surface of the bottom portion 55 is flat and has a step with the lower end 10A of the side surface portion 10. The depth dimension d ₇ of the step of the bottom portion 55 with respect to the lower end 10 A of the side surface portion 10 is the thickness dimension t ₉ or more of the covering member 62. Strictly speaking, the thickness t ₉ of the covering member 62 is set to be equal to or less than the depth dimension d ₇ of the step of the bottom portion 55 with respect to the lower end 10 A of the side surface portion 10. Then, in the bottom portion 55, three fixing holes 56 are formed in an annular shape and at equal intervals through the bottom portion 55. Further, a concave step portion 57 is formed on the lower surface of the bottom portion 55 so as to extend inward of the fixing holes 56 adjacent to the fixing holes 56. The depth dimension d ₈ of these concave steps 57 is equal to or greater than the thickness dimension t ₈ of the fixing claw 17 of the battery contact piece 53. Further, the distance L ₇ from the inner end of the concave step portion 57 to the fixing hole 56 is equal to or larger than the dimension L ₈ of the bent portion 17A of the fixing claw 17.

The battery contact piece 53 includes a substrate portion 58, a fixing claw 17, and an upright portion 18. The substrate portion 58 comes into contact with an electrode of either a dry battery or a secondary battery. Further, the fixing claw 17 is for fixing the battery contact piece 53 to the lid main body 52. Further, when the battery lid 61 is attached to the main body 3, the upright portion 18 makes electrical contact with a contact piece (not shown) provided on the main body 3. The substrate portion 58 is formed in a substantially circular shape. Further, three fixing claws 17 are provided on the outer peripheral portion of the substrate portion 58 in an annular shape and at equal intervals, corresponding to the fixing holes 56. Then, each of the fixing claws 17 is bent downward at a right angle to the substrate portion 58 in a state before being attached to the lid main body 52. On the other hand, the upright portion 18 extends laterally from the outer circumference of the substrate portion 58 and then is bent upward at a right angle. In the state of being attached to the lid main body 52, the battery contact piece 53 is inserted into the fixing hole 56 corresponding to the fixing claw 17, and the bent portion 17A on the tip side thereof is bent inward. .. At this time, as described above, the depth dimension d ₈ of the concave step portion 57 is equal to or greater than the thickness dimension t ₈ of the fixing claw 17, and the distance from the inner end of the concave step portion 57 to the fixing hole 56. Since L ₇ is equal to or larger than the dimension L ₈ of the bent portion 17A of the fixed claw 17, the bent portion 17A fits within the concave step portion 57. Further, the upright portion 18 is located near the inner surface of the side surface portion 10 of the lid main body 52.

The coating member 62 is formed of a filler 63 such as a synthetic resin that cures over time. The filler 63 itself is waterproof when cured. Therefore, the outer peripheral portion of the covering member 62 is watertightly fixed to the lower inner surface 10B of the side surface portion 10 of the lid main body 52. As a result, water is prevented from entering between the covering member 62 and the lid body 52.

The assembly process of the battery lid 51 will be described. The description of the first step and the second step of assembly will be omitted. In the third step of assembly, the filler 63 is filled in the space defined by the lower inner surface 10B of the side surface portion 10 and the bottom portion 55 in a posture in which the bottom portion 55 faces upward. Since the filler 63 has an appropriate fluidity, its surface becomes flat. Although there is a slight gap between the fixing hole 56 and the fixing claw 17, the surface tension of the filler 63 prevents the filler 63 from leaking from the fixing hole 56. Then, the filler 63 is cured over time to form the covering member 62. Then, the covering member 62 covers the fixing hole 56, the concave step portion 57, and the bent portion 17A of the fixing claw 17. Further, the covering member 62 is in close contact with the lid body 52 in a watertight manner. In this way, the battery lid 61 is assembled.

Further, since the bent portion 17A of the bent fixing claw 17, the fixing hole 56, and the concave step portion 57 are covered by the covering member 62, the appearance can be improved. Since the covering member 62 is in close contact with the lower inner surface 10B and the bottom portion 55 of the side surface portion 10 of the lid main body 52 in a watertight manner, even if water is splashed on the electric device 1, between the side surface portion 10 and the covering member 62. Water does not enter the electric device 1 from the above.

As described above, in the present invention, in the battery lid 61 having the lid main body 52 and the battery contact piece 53 attached to the lid main body 52, the lid main body 52 is provided with three fixing holes 56. The fixing claws 17 corresponding to these fixing holes 56 are provided in the battery contact piece 53, and the fixing claws 17 are inserted into the respective fixing holes 56 and bent to be locked, and the fixing holes are locked. By covering the 56 and the fixing claw 17 with the covering member 62, not only the battery contact piece 53 can be easily and surely fixed to the lid body 52 with a simple structure, but also the battery contact piece 53 can be fixed. The mounting structure of the battery can be hidden.

Further, in the present invention, the mounting structure of the battery contact piece 53 can be easily hidden by forming the covering member 62 with a filler 63 made of a material such as a synthetic resin that cures with time.

Further, in the present invention, since the covering member 62 is waterproof, the battery lid 61 of the waterproof electric device 1 can be easily constructed.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the invention. For example, in the first to third embodiments, the substrate portion of the covering member is a disk-shaped member made of a relatively hard synthetic resin, but may be a flexible sheet-like material. In this case, the bottom does not have to be flat as long as it is a developable surface. When the flexible sheet-shaped covering member is attached to the bottom of the developable surface in this way, the covering member can be attached without stretching and contracting, and without causing wrinkles on the covering member. Further, in each of the above embodiments, the battery contact piece is fixed to the bottom of the lid body, but it may be fixed to a position other than the bottom of the lid body and the fixed structure may be covered with a covering member.
