[Embodiment of device]

 An adapter according to an embodiment of the present invention for replacing a cylindrical mercury battery of HN-4N type with a cylindrical silver oxide battery of 4LR-44 type will be described with reference to FIGS. 1 and 2. As shown in FIG. 3B, the mercury battery 1 has a peripheral surface formed as an outer can 1a, a bottom 1b which is insulated from the outer can as a positive electrode, and a center of an upper insulating cover plate 1d. The negative electrode terminal 1c projects from the portion. The outer can 1a has a diameter of about 17 mm, the height including the negative electrode terminal 1c is about 45 mm, and the battery voltage is 5.6V.

As shown in FIG. 3A, the silver oxide battery 2 that replaces this battery has a peripheral surface formed as an outer can 2 a, the upper and lower surfaces of which are connected to the positive electrode terminal 2 b and the negative terminal from the center of the insulating sealing plate. The child 2c projects and is formed relatively small. The outer can 2a has a diameter of about 12 mm, a height of about 24 mm between the electrode terminals 2b and 2c, and a battery voltage of 6.0 V.

An alternative battery adapter 9 is a synthetic resin cylindrical insulator 10 having an outer diameter substantially the same as that of the mercury battery 1, and a cylinder having an inner diameter larger than the outer diameter of the silver oxide battery 2 by about 1 mm. The recessed portion 11 is formed, and the conductor 12 is inserted into the through hole 14 formed upward from the center of the base surface 13 of the insulator 10 so that the tip portion 12c projects about 1 mm from the bottom surface 11a of the recessed portion 11. There is. This conductor is made of brass, and a cylindrical pole portion 12a is erected at the center of the disk portion 12b and plated with chrome. The diameter of the through hole 14 is set so that the pole portion 12a is fitted therein. At this time, the disk portion 12b is brought into contact with the base surface 13 as an output terminal for the positive electrode of the silver oxide battery 2.

The depth of the recess 11 is such that when the silver oxide battery 2 is housed in the recess 11 and the positive electrode terminal 2b is in contact with the tip portion 12c, the negative electrode terminal 2c protrudes from the recess 11 by about 1.5 mm. It is set to do so. The height of the insulator 10 is such that the height between the disk portion 12b and the negative electrode terminal 2c is the same as that of the mercury battery 1 when the silver oxide battery 2 is housed in the recess 11 and the positive electrode terminal 2b is in contact with the tip portion 12c. The height is set to correspond to the height between the bottom surface 1b and the negative electrode terminal 1c.

The thus configured adapter 9 is used when using an HN-4N type mercury battery, for example, when using a substitute battery for a camera. The positive electrode terminal 2b of the silver oxide battery 2 is inserted downward into the recess 11 of the adapter 9 and brought into contact with the tip 12c. In this state, the negative electrode terminal 2c slightly projects from the tip of the recess 11. The disk portion 12b of the conductor 12 has a wide circular contact surface and conducts with the positive electrode terminal 2b to perform the same function as the positive electrode bottom surface 1b of the mercury battery 1. This allows the mercury battery 1 to be replaced with a small silver oxide battery 2 having substantially the same battery voltage while leaving the battery box of the camera as it is. When taking out the silver oxide battery 2, the adapter 9 is dropped downward.

An adapter for a cylindrical alkaline battery of 4SR-44 type, which is relatively small in size with respect to the mercury battery 1 and has substantially the same battery voltage, can be similarly constructed.

An adapter for replacing the HM-N type button type mercury battery with the LR-44 button type silver oxide battery will be described with reference to FIGS. 4 and 5. As shown in FIG. 6B, the mercury battery 5 is provided with a negative electrode sealing plate 5b that is insulated from the periphery and slightly protrudes on the upper surface of a disk-shaped positive electrode case 5a. Is covered with an insulating exterior sheet 5c. The outer diameter is about 16 mm, the height is about 11 mm, and the battery voltage is 1.4V.

As shown in FIG. 6A, the silver oxide battery 6 to be replaced with this battery has a disk-shaped positive electrode case 6a provided with a negative electrode sealing plate 6b having a peripherally insulated and slightly protruding periphery, and having a diameter of Has a relatively small outer diameter of about 12 mm and a height of about 5 mm, and the battery voltage is 1.44V.

Reference numeral 19 is an alternative battery adapter according to the present invention, which is a cylindrical insulator 20 made of synthetic resin having an outer diameter which is almost the same as that of the mercury battery 5 and an inner diameter larger than that of the silver oxide battery 6. The pole portion 22a of the conductor 22 formed by forming the slightly large cylindrical concave portion 21 and the pole portion 22a standing upright in the disk portion 22b and the center portion thereof The tip portion 22c is fitted into the through hole 24 formed upward from the portion so that the tip portion 22c projects about 1 mm from the bottom surface 21a of the recess 21, and the disc portion 22b is brought into contact with the base bottom surface 23. The height of the insulator 20 and the depth of the recess 21 are such that the negative electrode sealing plate 6b is recessed in the recess 21 when the silver oxide battery 6 is housed in the recess 21 and the bottom surface of the positive electrode case 6a is in contact with the tip 22c. The height between the disk portion 22b and the negative electrode sealing plate 6b is set to correspond to the height between the bottom surface of the mercury battery 5 and the negative electrode sealing plate 5b.

When using the adapter 19 configured as described above, the silver oxide battery 6 is housed in the recess 21 with the bottom surface of the positive electrode case 6a facing downward and brought into contact with the tip 22c, and the negative electrode sealing plate 6b is recessed. 21 is slightly projected from the tip. The wide circular disk portion 22b of the conductor 22 electrically connects the positive electrode case 6a to the outside through the pole portion 22a. As a result, the silver oxide battery 6 can be used as a substitute while leaving the battery box for the mercury battery 5 such as a camera.

An adapter for a SR-44 type button alkaline battery, which is relatively small in size with respect to the mercury battery 5 and has substantially the same battery voltage, can be similarly constructed.
