Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a battery case that replaceably houses a primary battery used as a power source for portable electronic equipment, and is particularly characterized by its battery terminal board.

<Prior Art> Since primary batteries are disposable, the battery case must have a structure that allows anyone to replace the batteries. By the way, in order to obtain a predetermined voltage and current from a plurality of batteries, portable electronic devices use a combination of series connection and parallel connection of batteries. Therefore, when replacing the battery, the positive or negative terminal of the battery must be replaced carefully and according to the instructions.

<Purpose of the invention> The invention provides a battery case that allows multiple batteries to be connected in series while all arranged horizontally, thereby making it possible to store all the batteries in the same direction. It is something.

<Example> As shown in FIG. 1, an electric megaphone has a horn part 3 that incorporates a horn speaker 1 and an amplifier board 2.
It consists of a handle portion 4, a battery case 7 formed by integrally connecting a first member 5 and a second member 6, a battery cover 8, and a microphone portion 9.

A notch 10 is formed in the axial direction on the rear lower side of the horn portion 3, and mating protrusions 11a and 11b are formed on both side edges of this notch. The handle portion 4 has grooves 12a and 12b on both sides opposite to the upper protrusion.
It is formed. The horn part 3 and the handle part 4 are designed so that their rear edges are flush on the same plane after assembly, and a ring-shaped protrusion 13 is provided on both rear edges. A groove 14 that engages with this protrusion 13 is provided in the second member 6. Further, a screw 15 is formed on the outer periphery of the second member 6 in the circumferential direction of the electric megaphone, and a screw 16 that fits into the screw 15 is provided on the battery cover 8.

The electric megaphone consisting of the above-mentioned parts first connects the first member 5 and the second member 6 of the battery case and fixes them with screws 17, and then attaches the amplifier board 2 to the battery case from the front of the electric megaphone. Also, attach the microphone part 9 to the rear with screws 18. Next, while roughly aligning the handle portion 4 to the integrated amplifier board 2, battery case 7, and microphone portion 9, grooves 12a, 12b are formed in the protrusions 11a, 11b of the handle portion 4 relative to the horn portion 3. The battery case 7 is slid onto the horn part 3 with the screws 19 by sliding the grooves 14 onto the protruding edges 13. At this time, align the volume knob 20 and the knob hole 21, and also close the power switch 22 and switch lever 2.
Align 3. And screw 1 of battery cover 8
6 and the screws 15 of the battery case 7 to assemble the electric megaphone.

As shown in FIG. 3, the battery case 7 is made up of a first member 5 that contacts the positive pole side of the primary battery and a second member 6 that contacts the negative pole side of the primary battery. It is formed into a substantially cylindrical shape so that eight pieces are arranged on the circumference.

The first member 5 includes a substantially cylindrical vertical wall 31 along the longitudinal direction of the AA battery, a horizontal wall 32 in contact with the + pole of the battery, and a portion close to the + pole that covers about 1/5 of the length of the battery. , a partition wall 33 that arranges eight batteries on the same circumference.
has. The partition wall 33 exists only between the batteries, and the outer circumferential side of the battery case is open, allowing the batteries to be taken in and out. One end of the battery terminal plate 34 is connected to the side wall 3
It is wound around and fixed around the first member 5, passes through the through hole 35 of the member 5, passes inside the first member 5, and the other end of its extension is connected to the negative pole of the adjacent battery.

The second member 6 extends approximately 1/2 the length of the battery from the negative pole side of the battery.
The partition wall 38 is provided to form eight recesses 37 for accommodating only four recesses. In this recess 37, the partition wall on the outer circumferential side of the battery case is formed with an inclined surface inclined at about 15 degrees to facilitate the insertion and removal of the battery. In order to fit the member 6 with the member 5, a gap is formed between the partition wall 38 and the protruding wall 39 on the inner peripheral side of the battery case. The tip of the vertical wall 31 of the member 5 is fitted into this gap, and the first
The member 5 and the second member 6 are integrally connected. Screwing 17 is performed to strengthen the connection between the two. Also, the members 5 and 6 are arranged so that the battery terminal plate 34 passes through them.
In order to form a collision gap, a step 36 is formed in the middle of the vertical wall 31 of the member 5, and this step 36
Hit 8. One end of the battery terminal plate 34 is fixed by being wrapped around the side wall 32 of the first member 5, and the part near the other end is passed through the gap between the mating member 5 and the second member 6 to be held down. It will be done. The other end of the battery terminal plate 34 is extended until it abuts the negative pole of the battery, and is deflected within the recess 40 upon abutting the battery.

When storing a battery in the battery case configured as described above, loosen the screw 15, remove the battery cover 8, and insert the negative pole side of the battery 41 into the recess 37 of the second member 6 along the inclined surface 38. At this time, the battery 41 hits the inclined surface 38 and the vertical wall 31 and is held so as not to fall. Next, the battery is pressed against the vertical wall 31 so that the positive electrode side of the battery contacts the battery terminal plate 34. Then, tighten the screws 16 of the battery cover 8 to the screws 15 of the battery case 7.

Next, when taking out the battery, remove the battery cover 8, grasp the center of the battery in the longitudinal direction, and pull it out so as to remove the + pole side. The battery is held obliquely against the inclined surface 38 and the vertical wall 31 so as not to fall.

<Effect of the invention> In the battery case of the invention, the battery terminal plate 34
is fixed by wrapping it around the side wall 32 of the first member 5, and the middle part near the other end is held down by passing through the gap between the members 5 and 6, so the battery terminal board does not have screws. Installed in. Battery terminal board 34
connects the + electrode of one battery and the - electrode of an adjacent battery, so even if the batteries are arranged horizontally, they can be connected in series. Therefore, in the above embodiment,
Eight batteries can be inserted in the same direction into the battery case and all can be connected in series. Of course battery terminal board 3
It is also possible to change the shape of 4 and connect them in series and parallel as appropriate.
