Description

本発明は、検電器を含む各種の電池機器が備える電池収納部における電池誤挿入防止構造に関する技術である。   The present invention is a technique related to a structure for preventing erroneous battery insertion in a battery storage section provided in various battery devices including a voltage detector.

通常、検電器を含む各種の電池機器は、駆動電源として用いられる乾電池などの各種の電池をその挿脱を自在に収納する電池収納部を備えている。この場合、電池の正極は電池収納部内の正極側電極板と、同負極は電池収納部内の負極側電極板と個別に常時接触させた状態のもとで電池収納部内に収納されことになる。そして、電池機器は、別途配設されている適宜のスイッチ機構を操作することで使用時には電路をＯＮとし、その使用を終えたときには電路をＯＦＦにすることができるようになっている。   Usually, various battery devices including a voltage detector include a battery storage unit that freely stores various batteries such as a dry battery used as a driving power source. In this case, the positive electrode of the battery is housed in the battery housing portion under the condition that the positive electrode plate in the battery housing portion and the negative electrode are always in contact with the negative electrode plate in the battery housing portion. The battery device can turn on the electric circuit when it is used by operating an appropriate switch mechanism provided separately, and can turn off the electric circuit when the use is finished.

しかし、従来からある電池収納構造によるときは、電池を誤挿入することにより電池収納部内の正極側電極板に負極が、負極側電極板に正極が接続されてしまい、電源投入時に通電できなかったり、内部回路に悪影響を及ぼすといった問題があった。   However, when the conventional battery storage structure is used, if the battery is inserted incorrectly, the negative electrode is connected to the positive electrode plate in the battery storage part and the positive electrode is connected to the negative electrode plate. There was a problem of adversely affecting the internal circuit.

このような電池の誤挿入を防止する先行技術としては、下記特許文献１に示されているように、電池の正極である突起部の直径よりも大径で、かつ、負極の直径よりも細径な切り欠き形状を呈する仕切り板を正極側電極板の手前に介在させることで、誤挿入された際に電池の負極が正極側電極板と非接触となるような構造を採用したものがある。
特開２００１−３３２２３６号公報 As a prior art for preventing such erroneous insertion of the battery, as shown in Patent Document 1 below, the diameter is larger than the diameter of the protrusion, which is the positive electrode of the battery, and smaller than the diameter of the negative electrode. Some have adopted a structure in which the negative electrode of the battery is not in contact with the positive electrode plate when it is erroneously inserted by interposing a partition plate having a large notch shape in front of the positive electrode plate. .
JP 2001-332236 A

しかし、特許文献１に開示されている電池の誤挿入防止構造は、あくまでも電池の誤挿入を防止することのみを目的としてわざわざ電池収納部内に仕切り板を設けたものであり、それだけ構造が複雑になってコスト高を招いてしまう不都合があった。   However, the structure for preventing erroneous insertion of the battery disclosed in Patent Document 1 has a purpose of providing a partition plate in the battery housing only for the purpose of preventing erroneous insertion of the battery, and the structure is complicated accordingly. There was an inconvenience that resulted in high costs.

本発明は、従来技術の上記課題に鑑み、電池の誤挿入を防止する目的とは異なる他の目的に供するために設けた構造部位を、電池の誤挿入を防止できる機能をも兼備させることにより、低コストのもとで電池の誤挿入を確実に防止することもできるようにした電池収納部における電池誤挿入防止構造を提供することを目的とする。   In view of the above-described problems of the prior art, the present invention provides a structural part provided for another purpose different from the purpose of preventing erroneous insertion of the battery, and also has a function of preventing erroneous insertion of the battery. Another object of the present invention is to provide a structure for preventing erroneous battery insertion in a battery storage section that can reliably prevent erroneous battery insertion at low cost.

本発明は、上記目的を達成すべくなされたものであり、一側端面に正極側突出部を、他側端面に負極側平坦部を有してなる少なくとも１以上の電池を通電可能に収納すべく形成された電池収納部において、電池の前記正極側突出部との接触を自在に配設される正極側導電金具片は、前記正極側突出部との接触面よりもその座高を高くして前記正極側導電金具片側を挿通させた固定用突起を介して、電池における前記正極側突出部との接触のみを自在に電池収納部側に位置固定させたことを最も主要な特徴とする。   The present invention has been made to achieve the above object, and accommodates at least one battery having a positive-side protruding portion on one side end face and a negative-side flat portion on the other side end face so as to be energized. In the battery housing portion formed accordingly, the positive electrode-side conductive metal piece that is freely arranged to be in contact with the positive electrode side protruding portion of the battery has a seat height higher than the contact surface with the positive electrode side protruding portion. The main feature is that only the contact with the positive electrode side protruding portion in the battery is freely fixed to the battery housing portion side through the fixing protrusion through which the positive electrode side conductive metal fitting one side is inserted.

この場合、前記正極側導電金具片は、該正極側導電金具片の対応部位を切り開いて立ち上がらせた固定用爪片を前記固定用突起と掛合させたり、前記正極側導電金具片を挿通させた前記固定用突起の突出部をカシメ状に溶着することで位置固定させることができる。   In this case, the positive-side conductive metal piece is formed by engaging a fixing claw piece that is raised by opening a corresponding portion of the positive-side conductive metal piece with the fixing protrusion or by inserting the positive-side conductive metal piece. It is possible to fix the position by welding the protruding portion of the fixing protrusion in a caulking shape.

本発明によれば、正極側導電金具片を位置固定するために設けた固定用突起に対し、電池の誤挿入を防止する機能をも兼備させたことにより、電池収納部に対し正極側導電金具片を位置固定することができるほか、電池の誤挿入を確実に防止することもできるので、製品コストの低減化に有効に寄与させることができる。   According to the present invention, the fixing protrusion provided for fixing the position of the positive electrode-side conductive metal piece also has a function of preventing erroneous insertion of the battery. In addition to being able to fix the position of the piece, it is also possible to reliably prevent erroneous insertion of the battery, which can effectively contribute to a reduction in product cost.

図１は本発明の一例の対応要部を、図２は本発明の他例の対応要部をそれぞれ拡大して示す断面図である。これらの図によれば、電池収納部１１は、一側端面２に正極側突出部４を、他側端面に図示しない負極側平坦部を有してなる少なくとも１以上の電池１を通電可能に収納すべく形成されている。   FIG. 1 is an enlarged cross-sectional view of a corresponding main part of an example of the present invention, and FIG. 2 is an enlarged view of a corresponding main part of another example of the present invention. According to these drawings, the battery housing portion 11 can energize at least one battery 1 having a positive side protruding portion 4 on one side end face 2 and a negative side flat portion (not shown) on the other side end face. Shaped to store.

すなわち、電池収納部１１は、例えば２以上の乾電池からなる電池１を直列に配列させた上で、その一側端面２に位置する正極側突出部４が正極側導電金具片２１に、他側端面に位置する負極側平坦部が図示しない負極側導電金具片にそれぞれ常時接触する状態のもとで収納できるケーシングなどのように適宜構造を備えて形成されている。なお、電池収納部１１は、図示は省略してあるが、複数の電池１を並列に配列させた状態のもとで収納できる構造を備えているものであってもよい。   That is, the battery storage unit 11 includes, for example, batteries 1 made of two or more dry batteries arranged in series, and the positive-side protruding portion 4 positioned on one side end face 2 is connected to the positive-side conductive metal piece 21 on the other side. The negative electrode side flat portion located on the end face is formed with an appropriate structure such as a casing that can be accommodated in a state where it is always in contact with a negative electrode conductive metal piece (not shown). In addition, although illustration is abbreviate | omitted, the battery accommodating part 11 may be provided with the structure which can be accommodated in the state which arranged the some battery 1 in parallel.

この場合、電池１の正極側突出部４との接触を自在に配設される正極側導電金具片２１は、正極側突出部４との接触面２２よりもその座高を高くして正極側導電金具片２１側を挿通させた固定用突起１２を介して、電池１における正極側突出部４との接触のみが自在となって電池収納部１１側に位置固定されている。なお、本発明における固定用突起１２は、１以上の適宜形状のもとで形成することができ、その数と位置とに対応させて正極側導電金具片２１側に挿通構造が形成されることになる。   In this case, the positive-side conductive metal piece 21 that is freely arranged to contact the positive-side protruding portion 4 of the battery 1 has a seat height higher than the contact surface 22 with the positive-side protruding portion 4 so Only the contact with the positive electrode side protruding portion 4 in the battery 1 is made freely through the fixing protrusion 12 inserted through the metal piece 21 side, and the position is fixed on the battery housing portion 11 side. In addition, the fixing protrusion 12 in the present invention can be formed under one or more appropriate shapes, and an insertion structure is formed on the positive electrode-side conductive metal piece 21 side corresponding to the number and position thereof. become.

これを図１に示す例に基づいてより詳しく説明すれば、正極側導電金具片２１は、その中央位置に電池１の正極側突出部４との当接を自在とした凸状接点２３からなる接触面２２が形成されている。   This will be described in more detail based on the example shown in FIG. 1. The positive electrode-side conductive metal piece 21 is composed of a convex contact 23 that can freely come into contact with the positive-side protruding portion 4 of the battery 1 at its center position. A contact surface 22 is formed.

しかも、正極側導電金具片２１には、凸状接点２３の両隣に位置する各部位に切欠部２４を形成してその基端２５ａ側から凸状接点２３方向へと立ち上がらせ、かつ、その先端部位を適長さ分切除してなる掛止縁２５ｂを有する固定用爪片２５が相互に向き合う配置関係のもとで各別に形成されている。   In addition, the positive electrode-side conductive metal piece 21 is formed with notches 24 in the respective parts located on both sides of the convex contact 23 so as to rise from the base end 25a side toward the convex contact 23, and the tip thereof. Fixing claw pieces 25 each having a latching edge 25b formed by cutting out a part of the portion by an appropriate length are formed separately based on an arrangement relationship facing each other.

また、電池収納部１１における各切欠部２４の凸状接点８６寄りでの正極側導電金具片２１との対面部位には、正極側導電金具片２１側を押し付けた際に各固定用爪２５の掛止縁２５ｂと掛合する固定用突起１２が各別に突設されている。   Further, when the positive-side conductive metal piece 21 side is pressed against the positive-side conductive metal piece 21 near the convex contact 86 of each notch 24 in the battery housing portion 11, The fixing protrusions 12 that are engaged with the latching edges 25b are provided so as to protrude.

この場合における各固定用突起１２は、それぞれの座高が位置固定時における接触面２２としての凸状接点２３の突出高さよりも高くなるようにして形成されており、これにより電池１が逆装填されてその負極側平坦部（例えば図３における電池１の負極側平坦部５参照）が凸状接点２３と対面する位置関係となっても、該凸状接点２３との接触を阻止する障害物として機能させることができることになる。   In this case, each of the fixing protrusions 12 is formed such that the seat height is higher than the protruding height of the convex contact 23 serving as the contact surface 22 when the position is fixed, whereby the battery 1 is reversely loaded. Even if the negative electrode side flat portion (see, for example, the negative electrode side flat portion 5 of the battery 1 in FIG. 3) faces the convex contact 23, as an obstacle to prevent contact with the convex contact 23 It will be able to function.

一方、本発明の他例を図２に基づいて詳しく説明すれば、正極側導電金具片２１は、図１におけると同様に、その中央位置に電池１の正極側突出部４との当接を自在とした凸状接点２３からなる接触面２２が形成されている。   On the other hand, if the other example of this invention is demonstrated in detail based on FIG. 2, the positive electrode side electrically-conductive metal fitting piece 21 will contact | abut with the positive electrode side protrusion part 4 of the battery 1 in the center position similarly to FIG. A contact surface 22 formed of a convex contact 23 that can be freely formed is formed.

しかも、正極側導電金具片２１には、凸状接点２３の両隣に位置する各部位に通孔２６が形成されており、各通孔２６と対面する電池収納部１１側には、正極側導電金具片２１側を押し付けた際に各通孔２６を介して挿通する固定用突起１２が突設されている。   Moreover, the positive electrode-side conductive metal piece 21 is formed with through holes 26 at positions located on both sides of the convex contact 23, and the positive electrode-side conductive material is provided on the battery housing part 11 side facing each through hole 26. A fixing protrusion 12 is provided so as to be inserted through each through hole 26 when the metal piece 21 side is pressed.

このため、固定用突起１２は、各通孔２６を挿通させることにより突出部２７として形成することができ、該突出部２７をカシメ状に溶着することで正極側導電金具片２１を電池収納部１１側に位置固定することができる。   For this reason, the fixing protrusion 12 can be formed as a protruding portion 27 by inserting each through hole 26, and the positive electrode-side conductive metal piece 21 is attached to the battery housing portion by welding the protruding portion 27 in a caulking shape. The position can be fixed to the 11 side.

この場合においても、溶着後の各突出部２７は、それぞれの座高が位置固定時における接触面２２としての凸状接点２３の突出高さよりも高くなるようにして形成されており、これにより電池１が逆装填されてその負極側平坦面（図示せず）が凸状接点２３と対面する位置関係となっても、該凸状接点２３との接触を阻止する障害物として機能させることができることになる。   Also in this case, each protrusion 27 after welding is formed such that the respective seat height is higher than the protrusion height of the convex contact 23 as the contact surface 22 when the position is fixed. Can be made to function as an obstacle that prevents contact with the convex contact 23 even if the negative electrode side flat surface (not shown) is in a positional relationship facing the convex contact 23. Become.

図３は、本発明を検電器に適用した場合の実施例を示す分解斜視図であり、図４は、図３における要部構造をその目視位置を変えて（ａ）〜（ｃ）として各別に示す斜視説明図である。   FIG. 3 is an exploded perspective view showing an embodiment when the present invention is applied to a voltage detector, and FIG. 4 shows the main part structure in FIG. 3 as (a) to (c) by changing the viewing position. It is a perspective explanatory view shown separately.

これらの図によれば、電池収納部１１としての機能も兼備させた検電器３１は、電池１として２本の乾電池が直列接続された状態で収納される筒状本体部３２と、該筒状本体部３２内の電池１の他側端面３に位置する負極側平坦部５に押出し方向での弾性を伴って接触する負極側導電金具片３７と、電池１の一側端面２に位置する正極側突出部４側へと至る正極電極板３８とを検出回路部３６に各別に付設して筒状本体部３２内に設置される検電用回路体３５と、電池１の正極側突出部４が位置する側の筒状本体部３２に対し所定範囲での回転とその着脱とが自在に施蓋される蓋状スイッチ部４０とを少なくとも備えてその全体が構成されている。なお、図示例は検電器３１であることから、筒状本体部３２の先端部３２ａ側には検電用回路体３５の検出回路部３６の前端部３６ａを覆って保護する透明なキャップ部３９が止着されている。   According to these figures, the voltage detector 31 that also functions as the battery storage unit 11 includes a cylindrical main body 32 that stores two dry batteries connected in series as the battery 1, and the cylindrical shape. A negative electrode-side conductive metal piece 37 that contacts the negative electrode-side flat portion 5 located on the other end surface 3 of the battery 1 in the main body 32 with elasticity in the pushing direction, and a positive electrode located on the one end surface 2 of the battery 1 A positive electrode plate 38 extending to the side protruding portion 4 side is separately attached to the detection circuit portion 36 and installed in the cylindrical main body portion 32, and the positive electrode side protruding portion 4 of the battery 1. The cylindrical main body portion 32 on the side where is located is provided with at least a lid-like switch portion 40 that can be freely rotated and attached in a predetermined range, and the whole is configured. Since the illustrated example is the voltage detector 31, a transparent cap portion 39 that covers and protects the front end portion 36 a of the detection circuit portion 36 of the circuit body 35 for voltage detection is provided on the distal end portion 32 a side of the cylindrical main body portion 32. Is fastened.

この場合、筒状本体部３２の頂端部３２ｂ側に施蓋される蓋状スイッチ部４０は、例えば円形の天板部４１と、該天板部４１から垂設された周壁部４２とで一体形成されており、その覆設時に該周壁部４２の開放端面４２ａを介して筒状本体部３１の鍔部３３側との当接が自在となっている。   In this case, the lid-like switch part 40 applied to the top end part 32 b side of the cylindrical main body part 32 is integrated with, for example, a circular top plate part 41 and a peripheral wall part 42 suspended from the top plate part 41. It is formed, and can be in contact with the flange 33 side of the cylindrical main body portion 31 through the open end surface 42a of the peripheral wall portion 42 at the time of covering.

しかも、蓋状スイッチ部４０における周壁部４２の内周面４３は、筒状本体部３１の頂端部３２ｂ側との間で必要となる動きに対応合致させることができる適宜の内部構造を付与することにより形成されている。   Moreover, the inner peripheral surface 43 of the peripheral wall portion 42 of the lid-like switch portion 40 provides an appropriate internal structure that can be matched with the movement required between the top end portion 32b side of the cylindrical main body portion 31. It is formed by.

また、蓋状スイッチ部４０には、図４（ｃ）に示すように天板部４１の内側面４１ａと周壁部４２の内周面４３とを介して正極側導電金具片２１が設置されており、該正極側導電金片２１により図３に示す正極電極板３８の側の接点部３８ａと、検電回路体３５が備える負極側導電金具片３７が生成するばね力により押出し方向に付勢されてその開蓋時に頂端部３２ｂ側からやや突出するように収容されている電池１の正極側突出部４との間を短絡させることができるようになっている。   Further, as shown in FIG. 4 (c), the positive electrode side conductive metal fitting piece 21 is installed in the lid-like switch portion 40 through the inner side surface 41 a of the top plate portion 41 and the inner peripheral surface 43 of the peripheral wall portion 42. The positive side conductive gold piece 21 is biased in the pushing direction by the spring force generated by the contact part 38a on the positive electrode plate 38 side shown in FIG. 3 and the negative side conductive metal piece 37 included in the voltage detection circuit body 35. Thus, when the lid is opened, the positive electrode side protruding portion 4 of the battery 1 accommodated so as to slightly protrude from the top end portion 32b side can be short-circuited.

この場合、正極側導電金具片２１の長さ方向さ方向での中央位置には、図４（ａ）からも明らかなように電池１の正極側突出部４との当接が自在な接触面２２である凸状接点２３が突設されているほか、該凸状接点２３の両隣に位置する各部位には、切り開くことにより切欠部２４を形成して基端２５ａ側から凸状接点２３方向へと立ち上がらせ、かつ、その先端部位を適長さ分切除してなる固定用爪片２５が相互に向き合う配置関係で各別に形成されている。   In this case, at the central position in the longitudinal direction of the positive electrode-side conductive metal piece 21, a contact surface that can freely come into contact with the positive-side protruding portion 4 of the battery 1 as is apparent from FIG. In addition to the projecting contact point 23 that is 22, a cutout portion 24 is formed in each part located on both sides of the projecting contact point 23 by cutting away from the base end 25 a side in the direction of the projecting contact point 23. The fixing claw pieces 25 are formed separately in an arrangement relationship facing each other.

また、各切欠部２４の凸状接点２３寄りに位置する部位と対面する天板部４１の内側面４１ａには、図４（ｃ）に示すように天板部４１側へと正極導電金具片２１を押し付けた際に各固定用爪片２５の掛止縁２５ｂと掛合する固定用突起１２が各別に突設されている。   Further, on the inner side surface 41a of the top plate portion 41 facing the portion located near the convex contact 23 of each notch portion 24, as shown in FIG. The fixing projections 12 that are engaged with the latching edges 25b of the fixing claw pieces 25 when the 21 is pressed are provided separately.

この場合における各固定用突起１２は、それぞれの座高がその位置固定時に凸状接点２３の突出高さよりも高くなるようにして形成されており、これにより電池１が逆装填されて負極側平坦部５が凸状接点２３と対面する位置関係となっても該凸状接点２３との接触を阻止する障害物として機能させることができることになる。   Each fixing protrusion 12 in this case is formed such that the seat height is higher than the protruding height of the convex contact 23 when the position is fixed, whereby the battery 1 is reversely loaded and the flat portion on the negative electrode side. Even if 5 is in a positional relationship facing the convex contact 23, it can function as an obstacle that prevents contact with the convex contact 23.

次に、上記構成からなる本発明の作用効果を図１に示す例に基づいて説明すれば、正極側導電金具片２１は、その中央位置に電池１の正極側突出部４との当接を自在とした凸状接点２３からなる接触面２２が形成されており、該正極側導電金具片２１には、凸状接点２３の両隣に位置する各部位に切欠部２４を形成してその基端２５ａ側から凸状接点２３方向へと立ち上がらせ、かつ、その先端部位を適長さ分切除してなる掛止縁２５ｂを有する固定用爪片２５が相互に向き合う配置関係のもとで各別に形成されている。   Next, the operation and effect of the present invention having the above-described configuration will be described based on the example shown in FIG. 1. The positive electrode-side conductive metal piece 21 is brought into contact with the positive-side protruding portion 4 of the battery 1 at the center position. A contact surface 22 formed of a convex contact 23 is formed freely. The positive-side conductive metal piece 21 is formed with a notch 24 at each part located on both sides of the convex contact 23 and its base end. The fixing claw pieces 25 each having a latching edge 25b formed by rising from the 25a side in the direction of the convex contact 23 and having the appropriate length of the distal end portion thereof are separated from each other. Is formed.

また、電池収納部１１における正極側導電金具片２１との対面部位には、該正極側導電金具片２１側を押し付けた際に各固定用爪２５の掛止縁２５ｂと掛合する固定用突起１２が各別に突設されているので、正極側導電金具片２１を電池収納部１１側に確実に位置固定することができる。   Further, the fixing protrusion 12 that engages with the latching edge 25b of each fixing claw 25 when the positive electrode side conductive metal piece 21 side is pressed against the positive electrode side conductive metal piece 21 side in the battery housing portion 11. Therefore, the positive-electrode-side conductive metal piece 21 can be reliably fixed to the battery housing portion 11 side.

しかも、各固定用突起１２は、座高が位置固定時における接触面２２としての凸状接点２３の突出高さよりも高くなるようにして形成されているので、電池１が逆装填されて例えば図３における負極側平坦部５が凸状接点２３と対面する位置関係となっても、該凸状接点２３との接触を確実に阻止する障害物として機能させることができる。   Moreover, each of the fixing protrusions 12 is formed such that the seat height is higher than the protruding height of the convex contact 23 as the contact surface 22 when the position is fixed. Even if the negative electrode side flat portion 5 in the position of the negative contact side faces the convex contact 23, it can function as an obstacle that reliably prevents contact with the convex contact 23.

したがって、本発明の図１に示す例によれば、電池収納部１１内への電池１の誤挿入を確実に防止することができる。このような作用効果は、図２に示す例や図４に示す実施例においても同様にして得ることができる。   Therefore, according to the example shown in FIG. 1 of the present invention, erroneous insertion of the battery 1 into the battery housing portion 11 can be reliably prevented. Such an effect can be obtained in the same manner in the example shown in FIG. 2 and the embodiment shown in FIG.

つまり、本発明によれば、正極側導電金具片２１を位置固定するために設けた固定用突起１２に対し、電池１の誤挿入を防止する機能をも兼備させたことにより、電池収納部１１に対し正極側導電金具片２１を位置固定することができるほか、電池１の誤挿入を確実に防止することもできるので、製品コストの低減化に有効に寄与させることができる。   That is, according to the present invention, since the fixing protrusion 12 provided for fixing the position of the positive electrode-side conductive metal piece 21 also has a function of preventing erroneous insertion of the battery 1, On the other hand, the position of the positive electrode-side conductive metal piece 21 can be fixed, and erroneous insertion of the battery 1 can be prevented with certainty, so that it is possible to effectively contribute to a reduction in product cost.
