Japanese Utility Model Publication No. 2-129668

However, in the prior art disclosed in Patent Document 1, each dry battery is supported at two points, a plus terminal and a minus terminal, between the plus electrode and the minus electrode of the housing portion. Therefore, almost all of the impact and vibration in the battery length direction when dropped or bumped are applied to the positive terminal and the negative terminal of the dry battery through the electrode on the housing portion side. In particular, the protruding plus terminal is less susceptible to impact in the battery length direction than the flat minus terminal, and there are cases in which the protruding portion is damaged.

As a result, when the dry battery is accommodated, the positive terminal can be accommodated without colliding with the contact surface in the depth direction of the concave portion, and the end surface around the positive terminal of the dry cell can be formed on the peripheral surface of the concave portion. It is possible to support. As a result, it is possible to prevent most of the impact and vibration in the length direction of the dry battery from being directly transmitted to the positive terminal of the dry cell, and it is possible to protect the positive terminal from the impact and vibration in the length direction of the dry cell.

(Embodiment)
(Constitution)
As shown in FIG. 1 to FIG. 3, the battery housing device 1 according to the embodiment of the present invention includes a box-shaped battery housing portion 10 having a substantially rectangular opening in a front view, minus electrodes 21 and 23, Positive electrodes 22 and 24 are provided.
The battery housing portion 10 includes short wall portions 14 and 15 which are wall portions on one end side and the other end side in the longitudinal direction, and long wall portions 16 and 17 which are wall portions on one end side and the other end side in the short side direction. A sill portion 11 that extends from end to end in the longitudinal direction is formed on the inner bottom portion at the center position in the lateral direction.

The sill portion 11 is configured to be lower than the short wall portions 14 and 15 and the long wall portions 16 and 17, and has a curved surface skirt along the outer shape of the dry battery to be accommodated. That is, the cross section is formed in a substantially mountain shape.
Thus, two battery chambers 10 a and 10 b that are separated by the sill portion 11 are formed in the battery housing portion 10. One battery is accommodated in each of the two battery chambers 10a and 10b.
In addition, the lower halves inside the long wall portions 16 and 17 of the battery chambers 10a and 10b are configured to rise in a concave shape along the shape of the dry battery to be accommodated.
Further, recessed portions 12 and 13 that can loosely accommodate the plus terminals of the dry battery are formed at the attachment positions of the plus electrodes 22 and 24 on the inner wall portion of the battery accommodating portion 10. Details of the recesses 12 and 13 will be described later.

The negative electrode 21 is an electrode that comes into contact with a negative terminal of a dry battery housed in the battery chamber 10a so as to be conductive, and is attached to the inner wall portion 15ia of the short wall portion 15 on the battery chamber 10a side. The positive electrode 22 is an electrode that is in contact with a positive terminal of a dry battery housed in the battery chamber 10a so as to be conductive, and is attached to the recess 12 formed in the inner wall portion 14ia of the short wall portion 14 on the battery chamber 10a side. Yes.
The minus electrode 23 is an electrode that comes into contact with the minus terminal of the dry battery housed in the battery chamber 10b so as to be conductive, and is attached to the inner wall portion 14ib of the short wall portion 14 on the battery chamber 10b side. The positive electrode 24 is an electrode that comes into contact with the positive terminal of the dry battery accommodated in the battery chamber 10b so as to be conductive, and is attached to the recess 13 formed in the inner wall portion 15ib of the short wall portion 15 on the battery chamber 10b side. Yes.

The negative electrodes 21 and 23 are composed of metal coil springs, and are elastically deformed so as to be compressed toward the inner wall side of the respective mounting positions by being pushed by the negative terminal when the dry battery is accommodated. And it is comprised so that self may be pressed on the negative | minus terminal of a dry cell with the elastic force at that time.
The plus electrodes 22 and 24 are made of metal leaf springs, and are pushed by the plus terminal when the dry battery is accommodated, and elastically deform toward the back side of the recesses 12 and 13 at the respective mounting positions. And it is comprised so that self may be pressed on the plus terminal of a dry cell with the elastic force at that time.

In the present embodiment, although not shown, the minus electrode 21 and the plus electrode 24 are electrically connected. That is, the battery accommodating device 1 of the present embodiment has a configuration in which two dry batteries accommodated in the battery chambers 10a and 10b are connected in series.
Although not shown, a terminal plate (not shown) that is electrically connected to the negative electrode 23 is provided on the outer wall 14eb on the back side of the inner wall 14ib. This terminal board has a role as an external terminal (-).

  Further, as shown in FIGS. 2 and 4A, the plus electrode 22 is bent and attached in a substantially U shape. Specifically, it is attached so as to extend from the inner wall portion 14ia to the outer wall portion 14ea on the back side through a through hole 18 (see FIG. 4A) provided in the lower portion of the concave portion 12. And the electrode part 22a which is a part by the side of the inner wall part 14ia of the plus electrode 22 is a part which contacts the plus terminal of a dry cell directly.

On the other hand, as shown in FIGS. 4A to 4C, the recess 12 communicates with a lower recess 121 formed in the center in the width direction of the inner wall portion 14ia constituting the battery chamber 10a and an upper portion of the lower recess 121. And an upper recess 122 formed as described above. Hereinafter, the contact surface in the depth direction of the recesses 12 and 13 is referred to as a “back surface”.
The lower recessed portion 121 is configured by a recessed portion that is recessed in a substantially trapezoidal shape in plan view that slightly expands in the width direction from the upper end to the lower end, and includes inclined wall portions 121a and 121b that serve as inner walls of the recessed portion. Furthermore, an inclined portion 121c is formed at the lower center of the back surface of the lower recessed portion 121. The inclined portion 121c is inclined toward the back side from the top to the bottom.

  The upper concave portion 122 is formed of a concave portion that is recessed in a substantially trapezoidal shape in a plan view in which the lower side expands from the lower end (the upper end of the lower concave portion 121) upward in the width direction. In addition, the upper side is composed of a concave portion that is recessed in a substantially rectangular shape in plan view having a side of the width of the upper end on the lower side. The upper concave portion 122 includes inclined wall portions 122a and 122c that form the inner wall on the lower side, and side wall portions 122b and 122d that form the inner wall on the upper side. Further, the upper concave portion 122 is formed with a recess up to the upper end of the inner wall portion 14ia, and the upper portion is open. Still further, in the present embodiment, the width L of the upper recess 122 is shorter than the diameter of the negative terminal of the battery to be accommodated in consideration of the removal of the battery, and the thumb tip of a general adult male is included. Configured to width.

A through hole 122e that opens in a substantially rectangular shape in a plan view for concealing the upper end portion of the plus electrode 22 is formed in the back surface of the upper recess 122 at a substantially central position.
Further, in the present embodiment, the depths of the recesses of the lower recess 121 and the upper recess 122 are the same and uniform, and at least a depth greater than the length of the plus terminal of the battery to be accommodated (for example, an AA dry battery). About 2.5 [mm]). In addition, the width of the concave portion 12 is longer than the diameter of the positive terminal of the dry battery accommodated even at the upper end portion of the lower concave portion 121 which is the smallest, and shorter than the diameter of the dry battery accommodated also above the upper portion of the upper concave portion 122 which is the largest. Configured to dimensions.

It should be noted that the back surface side of the upper concave portion 122 may also have a hem-indented shape so as to have a funnel shape, similar to the inclined wall portions 122a and 122c. In that case, the width L of the upper concave portion 122 does not need to stick to a dimension shorter than the diameter of the dry battery to be accommodated. The reason for this is that, with this configuration, the negative terminal of the dry battery contacts the inner wall portion 14ia even in the case of reverse connection in which the dry battery described later is housed in the reverse direction, so the positive electrode 22 in the recesses 12 and 13 and This is because there is no contact with 24.
Further, a portion around the recess 12 of the inner wall portion 14ia is formed as a flat surface, and this surface comes into contact with an end surface around the plus terminal when the dry cell is accommodated in the battery chamber 10a, and the plus terminal of the dry cell. Has a role to support the side. Hereinafter, this surface may be referred to as “support surface 14s”.

Further, as shown in FIG. 4A, the electrode portion 22 a of the plus electrode 22 is accommodated inside the recess 12. Specifically, the electrode portion 22a is disposed in the recessed portion 12 in a posture in which the electrode portion 22a stands obliquely upward at a predetermined inclination angle from the lower end on the back side of the lower recessed portion 121 toward the front side of the upper recessed portion 122. It has become.
Here, the inclination angle and length of the electrode portion 22a are such that when the dry battery is accommodated in the battery chamber 10a, the positive terminal pushes the electrode portion 22a toward the back side of the recess 12 so that both are in contact with each other in a conductive state. Thus, the electrode portion 22a is configured to have an inclination angle and a length such that the electrode portion 22a does not contact the back surface of the recess 12. At this time, the electrode portion 22a is elastically deformed in a direction in which the inclination angle is reduced by being pushed by the plus terminal of the dry battery, and presses itself against the plus terminal of the dry battery by the elastic force.

In addition, the inclination angle and length of the electrode portion 22a are such that when the dry battery is not accommodated, the entire electrode portion 22a is retracted deeper than the entrance of the recess 12 (for example, about 0.5 mm) The tilt angle and the length are such that they are retracted to the side).
Furthermore, the upper end portion 22T of the electrode portion 22a is configured to be curved toward the back side of the recess 12. And when the dry cell is not accommodated, the tip of the upper end 22T is configured to enter the inside of the through hole 122e. In other words, when the dry battery is accommodated, the electrode portion 22a is pushed by the plus terminal, and the upper end portion 22T enters the depth of the through hole 122e without contacting the inner surface of the upper recess 122 or the like. In the present embodiment, the through hole 122e is configured deeper than the length into which the upper end portion 22T enters.

  Here, the concave portion 13, the inner wall portion 15ib and the positive electrode 24 of the battery chamber 10b have the same configuration as the concave portion 12, the inner wall portion 14ia and the electrode portion 22a of the positive electrode 22 of the battery chamber 10a, and thus description thereof is omitted. That is, the configuration of the battery chamber 10b on the side of the recess 13 is obtained by replacing the reference numeral starting with 12 in FIG. 4A to FIG. 4C with 13, the reference numeral starting with 14, and the reference numeral starting with 22 with 24. Is almost the same. However, since the external terminal is not required on the short wall portion 15 side, the plus electrode 24 does not need to be bent in a substantially U shape and is electrically connected to the minus electrode 21, so that a part of the configuration is different (not shown). ). Further, the minus electrode 21 does not need to be connected to an external terminal and is electrically connected to the plus electrode 24, so that a part of the structure is different (not shown).

Next, the operation of each part when a dry cell is accommodated in the battery accommodating device 1 having the above configuration will be described.
As shown in FIG. 5A, in the battery accommodating device 1, the dry battery B1 is accommodated in the battery chamber 10a, and the dry battery B2 is accommodated in the battery chamber 10b in a normal direction. The dry cell B1 has a protruding plus terminal P1 on one end side in the longitudinal direction and a flat disk-like minus terminal M1 on the other end side. The dry battery B2 has a projecting plus terminal P2 on one end side in the longitudinal direction and a flat disk-like minus terminal M2 on the other end side.
In the state of being accommodated in a normal orientation, the plus terminal P1 of the dry battery B1 is in contact with the plus electrode 22 and the minus terminal M1 is in contact with the minus electrode 21. In addition, the plus terminal P2 of the dry battery B2 is in contact with the plus electrode 24, and the minus terminal M2 is in contact with the minus electrode 23.

  Since the plus electrode 24 and the minus electrode 21 are electrically connected, the dry batteries B1 and B2 are connected in series. In this state, it is possible to supply power to the electronic device by bringing the external terminal (+) and the external terminal (-) into contact with the plus terminal and the minus terminal of the power supply circuit of the electronic device directly or via an electric cable. It has become. Here, the terminal portion 22b which is a portion of the plus electrode 22 on the outer wall portion 14ea side has a role as an external terminal (+), and is fixed by heat caulking in this embodiment. Therefore, the terminal portion 22b is provided with a through hole 22h (see FIG. 4A) through which the thermal caulking protrusion is inserted.

When the dry battery B1 is accommodated, the plus terminal P1 is accommodated in the recess 12 as shown in FIGS. 5 (a) and 5 (b). In addition, the shoulder S1, which is the end surface around the plus terminal P1 of the dry battery B1, is in contact with the support surface 14s around the recess 12 of the inner wall portion 14ia. The lid portion other than the positive electrode of the dry battery is referred to as a “shoulder”.
Here, when the dry battery B1 is accommodated, the plus terminal P1 comes into contact with the plus electrode 22 and pushes the electrode portion 22a into the back side of the recess 12 as shown in FIG. At this time, the upper end portion 22T of the electrode portion 22a is hidden from the upper side by the ceiling portion 122ec of the through hole 122e before the dry battery B1 is accommodated. Get into.

Further, after the dry battery B1 is accommodated, a gap d1 is formed between the inner surface and the portion closest to the inner surface of the recess 12 below the upper end 22T of the electrode portion 22a. In this state, since the biasing force of the plus electrode 22 and the minus electrode 21 is stronger than the biasing force of the minus electrode 21, the shoulder S1 of the dry battery B1 is in contact with the support surface 14s, and the plus terminal P1 is in a state where it can no longer move to the back side of the recess 12. That is, the dry battery B1 is in a state of being supported by the two surfaces of the negative electrode 21 side and the support surface 14s of the battery chamber 10a of the battery housing portion 10. In addition, since the width L of the upper concave portion 122 is configured to be longer than the diameter of the positive terminal of the dry battery, the positive terminal P1 is in a state where no force other than the elastic force from the electrode portion 22a is applied.
About the effect | action demonstrated above, since it becomes the same also about the battery chamber 10b side in which dry battery B2 was accommodated, description is abbreviate | omitted about the battery chamber 10b side.

Next, the operation of the recess 12 when a dry cell is accommodated in the reverse direction in the battery chamber 10a of the battery accommodating device 1 having the above configuration will be described.
As shown in FIG. 6A, in the battery accommodating device 1, the dry battery B1 is accommodated in the battery chamber 10a in the reverse direction, and the dry battery B2 is accommodated in the battery chamber 10b in the normal direction.
Here, since the width dimension of the upper end portion of the lower recessed portion 121 of the battery chamber 10b is formed so as to fit the convex electrode of the plus terminal P1 of the dry cell B1, the minus terminal M1 of the dry cell B1 is blocked by the inner wall portion 14ia. It is.

Further, the negative terminal M1 of the dry battery B1 has a diameter larger than the width of the concave portion 12 of the battery chamber 10b, and the negative terminal M1 has a flat configuration. Therefore, when the dry battery B1 is accommodated in the opposite direction, the end surface of the dry battery B1 on the minus terminal M1 side is in a state of being supported by the support surface 14s without the minus terminal M1 entering the recess 12. Here, since the electrode portion 22a of the plus electrode 22 is disposed at a position retracted from the entrance of the recess 12, the minus terminal M1 and the plus electrode 22 are connected as shown in FIG. For example, a gap of a distance d2 is open between the electrode portion 22a. Therefore, the electrode portion 22a does not jump out of the concave portion 12 and comes into contact with the negative terminal M1.
About the effect | action demonstrated above, since it becomes the same also about the battery chamber 10b side when the dry battery B2 is accommodated in the reverse direction, description is abbreviate | omitted about the battery chamber 10b side.

(Operation and effect of the embodiment)
The battery accommodating device 1 according to the present embodiment includes a battery accommodating portion 10 that accommodates a dry battery, and inner wall portions 14ia and 15ib that are portions of the short wall portions 14 and 15 of the battery accommodating portion 10 that face the positive terminal of the dry cell. Provided are plus electrodes 22 and 24 that are in contact with the plus terminals of the dry cell. In addition, the negative electrodes 21 and 23 provided on the inner wall portions 15ia and 14ib, which are portions of the short wall portions 14 and 15 of the battery housing portion 10 facing the negative terminal of the dry cell, are in contact with the negative terminal of the dry cell. Prepare. Further, the battery housing portion 10 includes recesses 12 and 13 formed in the inner wall portions 14ia and 15ib for housing the positive terminals of the dry cells, and the positive terminals of the positive terminals formed around the recesses 12 and 13 when the dry batteries are housed. Support surfaces 14 s and 15 s that come into contact with the peripheral end surfaces are provided.

  With this configuration, the positive terminals of the dry batteries accommodated in the battery chambers 10a and 10b are accommodated in a state where they are in contact with the positive electrodes 22 and 24 and do not collide with the inner surfaces of the recesses 12 and 13, The support surfaces 14s and 15s around the recesses 12 and 13 can support the end surface around the plus terminal. Accordingly, the dry battery can be held by the two surfaces of the negative electrode 21 side of the battery chamber 10a and the support surface 14s, and the two surfaces of the negative electrode 23 side of the battery chamber 10b and the support surface 15s. It becomes possible. As a result, for example, it is possible to prevent most of the impact and vibration in the length direction of the dry battery from being directly transmitted to the positive terminal of the dry battery due to the impact when the product using the battery housing device 1 is dropped. As a result, the positive terminal can be protected from impact or vibration in the length direction of the dry battery.

Further, in the battery housing device 1 according to the present embodiment, the plus electrodes 22 and 24 are further configured from members (plate springs in the embodiment) that are elastically deformed along the length direction of the dry battery.
With this configuration, the plus electrode can be reliably brought into contact with plus terminals having various lengths.
Further, in the battery accommodating device 1 according to the present embodiment, the upper concave portions 122 and 132 above the positive terminal accommodating positions of the concave portions 12 and 13 are wider than the lower concave portions 121 and 131 below the upper concave portions 121 and 131. The upper part is open.
If it is this structure, it will become possible to form a clearance gap wider than the width | variety of the lower recessed parts 121 and 131 between the back surface of the recessed parts 12 and 13 and the upper end surface of the positive terminal of a dry cell. As a result, it becomes possible to easily put a fingernail or the like between the dry battery above the plus terminal and the back surface of the concave portion, so that the dry battery can be easily taken out.

Further, the battery accommodating device 1 according to the present embodiment further has a substantially trapezoidal shape in a plan view in which the lower side of the upper recesses 122 and 132 is widened from the lower end (the upper end of the lower recesses 121 and 131) upward in the width direction. It is formed from the recessed part dented in. In addition, the upper side of the upper recesses 122 and 132 is constituted by a recess that is recessed in a substantially rectangular shape in plan view having a side of the width of the upper end on the lower side.
If it is this structure, the positive terminal will be guided to the accommodation position (lower recessed part 121 and 131) at the time of accommodation of a dry cell with the inclined surfaces of the inclined wall parts 122a and 122c and 132a and 132c which are inner walls on the lower side. It becomes possible. Thus, for example, when the positive terminal of the dry battery is accommodated along the upper side wall portions 122b and 132b of the upper recesses 122 and 132, the positive terminal along the slopes of the lower inclined wall portions 122a and 132a. Can be smoothly accommodated in the accommodation position (lower recess 121).

  Further, in the battery housing device 1 according to the present embodiment, the plus electrodes 22 and 24 are configured by leaf springs. Further, the plate-like electrode portions 22a and 24a that are in contact with the positive terminals of the leaf springs are fixed at one end below the back side of the recesses 12 and 13, and the other end is the front side of the recesses 12 and 13. It is arrange | positioned in the state which stood up diagonally toward upper direction. The upright electrode portions 22a and 24a are configured to be pushed by the plus terminal and elastically deformed and pushed into the back side of the recesses 12 and 13 when the dry battery is accommodated. Further, ceiling portions 122ec and 132ec for hiding the upper end portions 22T and 24T are provided on the upper ends of the upper end portions 22T and 24T of the electrode portions 22a and 24a pushed into the back sides of the concave portions 12 and 13 of the battery housing portion 10, respectively. ing.

With this configuration, the top ends 22T and 24T of the positive electrodes 22 and 24 can be hidden from the side where the dry batteries are accommodated by the ceiling parts 122ec and 132ec when the dry batteries are accommodated. As a result, it is possible to prevent the tip from entering between the nails and damaging the fingertip or damaging the plus electrodes 22 and 24 when removing the dry batteries from the battery chambers 10a and 10b.
Further, in the battery housing device 1 according to the present embodiment, the positive electrodes 22 and 24 are such that the contact portions with the positive terminals are located inside the support surfaces 14 s and 15 s around the recesses 12 and 13. It is arranged.
With this configuration, when the dry battery is accommodated in the reverse direction, the negative terminal of the dry battery and the positive electrodes 22 and 24 in the recesses 12 and 13 are not in contact with each other, and reverse connection can be prevented.

(Modification)
In the above embodiment, the through holes 122e and 132e are provided in the back surfaces of the recesses 12 and 13, and the top end portion 22T of the electrode portion 22a is concealed from the side where the dry battery is accommodated by the ceiling portions 122ec and 132ec. did. Not limited to this configuration, for example, the recesses 12 and 13 are configured as deeper recesses, and the tip of the upper end 22T after being pushed in with the plus terminal comes to a position in front of the inner surface of the recess. Thus, other configurations such as a configuration in which a ceiling portion is provided on the upper portion may be employed.
Further, in the above embodiment, the upper end portion 22T of the electrode portion 22a of the plus electrode 22 configured from a leaf spring is configured to bend toward the back side of the concave portion so that the tip end portion is obliquely upward. It is not limited to the configuration. For example, instead of the upper end portion 22T, as shown in FIG. 7, a configuration may be adopted in which the upper end portion 22Tr has a shape that is rounded so that the tip portion faces obliquely downward. In this configuration, the claw is not caught at the tip when the dry battery is taken out, and thus it is possible to eliminate the ceiling 122ec indicated by a broken line in FIG.

Moreover, although the said embodiment demonstrated and demonstrated the structure which employ | adopts a coil spring as the minus electrodes 21 and 23 and employ | adopted the leaf | plate spring as the plus electrodes 22 and 24, it is not restricted to this structure. For example, the negative electrodes 21 and 23 may be configured by leaf springs, and the positive electrodes 22 and 24 may be configured by coil springs. Moreover, as long as there exists the same effect | action, it is good also as a structure which employ | adopts not only a coil spring and a leaf | plate spring but another spring.
Moreover, in the said embodiment, although it was set as the structure which accommodates two dry batteries and connects the dry batteries in series, it is not restricted to this structure. For example, two dry batteries may be connected in parallel. Moreover, it is good not only as a structure which accommodates two dry batteries, but as another structure, such as the structure which accommodates only one dry battery, or the structure which accommodates three or more.

  Moreover, in the said embodiment, although it was set as the structure which arranges and accommodates a dry cell in the battery accommodating part 10 in parallel, it is not restricted to this structure, It combined the structure arranged in series, the structure arranged in series, and the structure arranged in parallel.
