[Technical field to which the device belongs]

 The present invention relates to a battery storage device, and more particularly to a battery storage device that can store and use not only a battery having a specific shape but also a battery having a different shape such as an outer diameter and a shaft length. Is.

[0002]

[Prior art]

 Most of the batteries are standardized.For wireless microphones, for example, an AA type or AAA type primary or secondary battery is usually used because of the size that can be stored in the grip. ing.

However, in particular, such as an infrared wireless microphone for karaoke, although it consumes a relatively large amount of power, it is used for a long time without being charged, and there is a restriction that the charging time is until the next lending time. If it is imposed, a special non-standard assembled battery 1 as illustrated in FIG. 4A may be required in consideration of the battery capacity and charging characteristics. Note that the single and single type secondary batteries cannot be applied to wireless microphones due to their size and weight.

The battery pack 1 introduced here has a larger diameter than that of, for example, an AA battery, but it is heated by two cylindrical secondary batteries 2 and 3 having a short axial length connected in series. The shrinkable sleeve 4 is integrally connected. Therefore, a battery storage case having a size capable of storing the assembled battery 1 is provided in the grip of the microphone.

[0005]

[Problems to be solved by the device]

 However, since such an assembled battery 1 is special, it is difficult to immediately replenish it if it fails or is lost unless it is in stock.

Assuming such a case, as shown in FIG. 4 (b), the outer diameter is usually set so that a closest AA battery 5, for example, can be substituted. A cylindrical spacer 6 equivalent to the battery 1 may be prepared as an optional component, but this has the following problems.

That is, as for the thickness (outer diameter), the spacer 6 can surely deal with it, but it cannot deal with the difference in axial length. Further, since the spacer 6 is an optional component, it is easily lost if it is removed from the package. Further, it takes time and effort to attach the spacer 6 to the battery 5 as a substitute, which is not lost.

Such a problem is not limited to the case where the special battery pack 1 described above is adopted, and when the standardized batteries that are commercially available are used interchangeably, for example, a single battery The same problem occurs when a three-dimensional battery runs out and a hand-held irregular-shaped battery, for example, a flat-shaped cylindrical battery called a AAA battery or a “gum battery” is substituted.

The present invention has been made in order to solve such a conventional problem, and its purpose is to load and use a battery other than the original battery to be used without any trouble. Another object of the present invention is to provide a battery storage device capable of performing the above.

A possible adapter holder and a conductive metal spring for urging the adapter holder toward the positive electrode lead-out terminal side are provided, and the adapter holder has the negative electrode lead-out terminal through the metal spring. It is characterized in that a relay terminal electrically connected to is provided.

As described above, since the adapter holder having the relay terminal is biased by the metal spring toward the positive electrode lead-out terminal side, the deformed batteries having different axial lengths within the sliding allowance range of the adapter holder. Can correspond to.

Further, according to a second aspect of the present invention, a guide groove formed between the battery case and the adapter holder is formed along the battery housing direction, and slides in a state of being engaged with the guide groove. It is characterized in that a guide holding means composed of a possible engaging claw is provided.

According to this, since the adapter holder is held in the battery case by the guide holding means, there is no risk that the adapter holder will be accidentally dropped from the battery case and lost, and when the battery is assembled. It will be easier.

According to a third aspect of the present invention, the adapter holder includes a bottom substrate facing the positive electrode lead terminal, and a tubular shape of a specific shape that extends from a peripheral edge of the bottom substrate toward the positive electrode lead terminal side. A sleeve that allows only a battery to be received therein, the relay terminal having a first contact disposed on the bottom substrate and a second contact provided so as to be exposed at an open end surface of the sleeve. It is characterized by having a contactor.

According to this, a cylindrical battery of a specific shape (for example, an AA type battery) is arranged between the positive electrode lead terminal of the battery case and the bottom substrate of the adapter holder, and the negative battery terminal thereof is the relay terminal. Contact the first contact. On the other hand, in the case of other deformed batteries (for example, special assembled batteries), the negative electrode battery terminal side does not enter the sleeve of the adapter holder but contacts the open end surface of the adapter holder, You will be in contact.

The invention according to claim 4 is characterized in that the first contactor and the second contactor are formed by a single metal plate. Can be easily incorporated into the holder.

According to a fifth aspect of the present invention, the second contact is arranged at an opening end face of the sleeve at an interval of 180 degrees so as to fit the negative battery terminal of the flat rectangular cylindrical battery. According to this, it is possible to use not only a cylindrical battery but also a so-called gum battery having a flat rectangular tubular battery.

[0018]

[Embodiment of device]

 Next, in order to better understand the technical idea of the present invention, its embodiments will be described. FIG. 1 is an exploded perspective view of the battery housing device 10, and FIG. 2 is a sectional view of the assembled battery device. The battery storage device 10 is intended to be stored in the grip of the wireless microphone.

According to this, the battery housing device 10 includes the battery case 11 formed of an elongated box body having an open upper surface. In this example, the one special assembled battery 1 and the two AA batteries 5 described above with reference to FIG. 4 can be used interchangeably. Therefore, two batteries can be used in the battery case 11. A battery storage portion 12 having a length sufficient to store the AA batteries 5 in series and having a width corresponding to the outer diameter of the special assembled battery 1 is provided. .

A positive electrode lead terminal 13 is provided on one end wall of the battery housing portion 12 which faces the length direction, and a negative electrode lead terminal 14 is arranged on the other end wall. Each of these terminals 13 and 14 may be a known one. Notches 11a and 11a for facilitating the removal of the battery from the battery housing portion 12 are formed on both side walls of the battery case 11 near the positive electrode lead-out terminal 13 side. Tongue-shaped holding pieces 11b, 11b formed to elastically hold the special assembled battery 1 housed in the battery housing portion 12 are provided at approximately middle portions of both side walls.

An adapter holder 15 is slidably provided along the length direction of the battery housing portion 12 in the battery housing portion 12 near the negative electrode lead terminal 14 side. According to this example, the adapter holder 15 includes a bottom substrate 15a facing the positive electrode lead terminal 13 and a sleeve 15b formed to extend from the peripheral edge of the bottom substrate 15a toward the positive electrode lead terminal 13 side. ing.

In this case, the sleeve 15b has a kamaboko shape and is sized to receive only a specific cylindrical battery, in this example, an AA battery 5 and a cylindrical battery having a smaller outer diameter. Therefore, the special assembled battery 1 having a larger outer diameter than the AA battery 5 comes into contact with the open end surface 15c of the sleeve 15b.

A guide holding means 16 is provided between the adapter holder 15 and the battery case 11 to hold the adapter holder 15 in the battery case 11 in a slidable state. In this example, the guide holding means 16 is composed of a guide groove 16a formed on the battery case 11 side and an engaging claw 16b formed on the lower edge of the sleeve 15b.

Although only one guide groove 16a and one engaging claw 16b are shown in FIG. 1, in practice, the guide groove 16a and the engaging claw 16b are provided in a pair on the left and right. By forcibly pushing the adapter holder 15 into the battery housing portion 12, the engaging claws 16b and 16b are engaged with the corresponding guide grooves 16a and 16a with elastic deformation. It has become.

The adapter holder 15 is provided with a relay terminal 17 for pulling out the negative electrode. The relay terminal 17 includes a first contactor 17a attached to the bottom substrate 15a and a second contactor 17b disposed on the opening end surface 15c of the sleeve 15b.

In this case, the first contactor 17a and the second contactor 17b are formed of a single metal plate, whereas the first contactor 17a is formed in a substantially circular shape. The second contactor 17b is formed in a strip shape, is routed along the inner surface of the sleeve 15b, and is then exposed at the opening end surface 15c thereof. As shown in FIG. 2, the first contactor 17a is folded back along the back surface side (the negative electrode lead terminal 14 side) of the bottom substrate 15a.

A conductive metal spring that elastically urges the adapter holder 15 toward the positive electrode lead terminal 13 side and electrically contacts the first contact 17 a of the negative electrode lead terminal 14 18 is attached. Therefore, the relay terminal 17 is held in a conductive state with the negative electrode lead terminal 14 via the metal spring 18.

In the above-mentioned configuration, in the state where the battery is not housed, the adapter holder 15 is placed at the position which is most biased to the positive electrode lead terminal 13 side by the metal spring 18. When the special assembled battery 1 is put into the battery housing 12 in this state, the positive electrode battery terminal 1a contacts the positive electrode lead-out terminal 13, and the negative electrode battery terminal 1b contacts the open end surface 15c of the sleeve 15b. While pushing back the holder 15 against the metal spring 18, the holder 15 is electrically contacted with the second contactor 17b exposed on the opening end surface 15c.

In this way, the negative battery terminal 1b of the special assembled battery 1 is brought into conduction with the negative electrode lead-out terminal 14 via the relay terminal 17 and the metal spring 18, whereby the microphone unit (not shown) from the special assembled battery 1 is brought into contact. Power is supplied to.

In this example, the negative battery terminal 1b of the special assembled battery 1 is exposed in a cylindrical shape from the electrically insulating sleeve 4, and correspondingly, the negative battery terminal 1b is provided at the bottom of the battery housing portion 12. A charging terminal (negative electrode side) 19 made of a leaf spring that is in contact with the negative electrode battery terminal 1b is provided.

That is, the charging terminal 19 is connected to a charging circuit (not shown) via the circuit board 20 attached to the bottom of the battery case 11, and the special assembled battery 1 is charged by the same special assembly. With the battery 1 stored in the battery storage portion 12, the charging is performed from the charging circuit via the positive electrode lead terminal 13 and the negative electrode side charging terminal 19.

On the other hand, when the special assembled battery 1 cannot be used due to insufficient charging or failure, the AA battery 5 is used instead as shown in phantom lines in FIGS. 1 and 2. Use two. Since the AA battery 5 is received in the sleeve 15b of the adapter holder 15, the negative battery terminal 5b of the one AA battery 5 pushes the adapter holder 15 slightly against the metal spring 18 and pushes it back. It comes into contact with the first contactor 17a of 17.

In this case, since the AA battery 5 has a smaller outer diameter than the special assembled battery 1, it cannot be held by the sandwiching pieces 11b and 11b of the battery case 11, but the two AA batteries 5 are Since the metal spring 18 pushes the positive electrode lead-out terminal 13 side and the negative electrode battery terminal 5b side of one AA battery 5 is covered with the sleeve 15b, there is no possibility of easily falling off from the battery housing portion 12.

In this way, according to this battery storage device, the AA battery 5 can be used as a substitute for the special assembled battery 1. Even if a secondary battery is used as the AA battery 5, it cannot be charged from the charging terminal 19 in this battery housing device.

FIG. 3 shows an example in which it can be applied to a flat rectangular tubular battery 21 which is a so-called gum battery. In this case, the sleeve 15b of the adapter holder 15 has a gate shape so as to obtain a stable contact state with the flat rectangular tubular battery 21.

Correspondingly, the second contactor 17b of the relay terminal 17 is bifurcated, and each of them is arranged horizontally on each leg of the open end face 15c of the sleeve 15b with an interval of 180 degrees. To be done. Therefore, when the flat rectangular tubular battery 21 is used, by placing the battery 21 sideways in the battery housing portion 12 as shown in FIG. It comes into contact with the contacts 17b, 17b.

The above example is for the case where the special assembled battery, the AA type battery, and the flat rectangular tube battery are used interchangeably, but the present invention is not limited to this, and for example, a single battery is used. The present invention can be applied to any of tubular batteries ranging from type to size A type.

That is, according to the invention of claim 1, since the adapter holder having the relay terminal is biased toward the positive electrode lead-out terminal side by the metal spring, the axial length is within the sliding allowable range of the adapter holder. Different shape batteries can be used.

According to the second aspect of the invention, since the adapter holder is held in the battery case by the guide holding means, there is no risk that the adapter holder will be accidentally detached from the battery case and lost. Also, the labor for incorporating the battery is simplified.

According to the third aspect of the invention, the cylindrical battery having a specific shape (for example, an AA battery) is arranged between the positive electrode lead terminal of the battery case and the bottom substrate of the adapter holder, and the negative electrode The battery terminal contacts the first contactor of the relay terminal. On the other hand, in the case of other deformed batteries (for example, special battery packs), the negative battery terminal side does not enter the sleeve of the adapter holder but contacts the open end surface of the adapter holder and contacts the second contact. In any case, a good electrical contact state can be obtained.

According to the invention of claim 4, since the first contactor and the second contactor of the relay terminal are formed of one metal plate, the relay terminal can be obtained at low cost and The joint terminal itself can be easily incorporated into the adapter holder.

According to the invention of claim 5, the second contact of the relay terminal is arranged at an interval of 180 degrees on the open end face of the sleeve so as to fit the negative electrode battery terminal of the flat rectangular tubular battery. This makes it possible to use not only a cylindrical battery but also a so-called gum battery having a flat rectangular tubular battery.
