Description

【０００１】
【発明の属する技術分野】
本発明は、電池の装着構造に関する。
【０００２】
【従来の技術】
本発明は、先行技術の調査を行なうことなく、公知・効用の技術をもとに開発した発明であるため、出願人が知っている先行技術は、文献公知発明に該当しない。以下、公知・効用の電池の装着構造について説明する。
【０００３】
電気設備には接地のための接地線が配設されている。三相電流を用いた機器に事故が発生した場合には、接地線に零相電流以外の電流が流れることになる。このため、接地線に流れる零相電流以外の電流を検出して警報を発する絶縁監視端末装置が用いられる。この絶縁監視端末装置には、何らかの事故により装置に電源を供給できなくなったときに、非常用としてバックアップ用電源を供給するための電池が装着されている。
【０００４】
この場合、絶縁監視端末装置の内部のプリント板と電池とを接続する手段として、従来は電池に着脱自在にコネクタを接続し、当該コネクタをリード線を介してプリント板に接続している。
【０００５】
【発明が解決しようとする課題】
ところが、電池にコネクタを取り付ける作業が必要になるだけでなく、コネクタとリード線とを用いることからコスト高になる。
【０００６】
そこで本発明は、斯かる課題を解決した電池の装着構造を提供することを目的とする。
【０００７】
斯かる目的を達成するための請求項１に係る電池の装着構造の構成は、電池を保持する保持部と、当該保持部へ向かって電池を押圧する押圧部と、該押圧部によって押圧された電池の端子の部分が押圧されると共に電源需要部に直接に結合された接続導体とを有し、前記押圧部が電池を前記接続導体に常時押圧するようにしたことを特徴とする。
【０００８】
斯かる電池の装着構造では、保持部へ電池を入れると、押圧部が電池を接続導体に常時押圧して電池と接続導体との通電を確保し、接続導体を介して電池からプリント板等の電源需要部に直接に通電される。
【０００９】
請求項２に係る電池の装着構造の構成は、請求項１において、前記押圧部は弾性部材で形成されたことを特徴とする。
【００１０】
斯かる電池の装着構造では、押圧部を変形させて保持部へ電池を押し込むと、弾性部材の復元力により電池が保持部へ向かって常時押圧される。
【００１１】
請求項３に係る電池の装着構造の構成は、請求項２において、前記押圧部は、前記保持部の両側に前記保持部と一体に形成され、電池が両側の前記押圧部によって抱え込まれるようにしたことを特徴とする。
【００１２】
斯かる電池の装着構造では、保持部へ押し込んだ電池が、両側の前記押圧部によって抱え込まれるようにして保持部へ常時押圧される。
【００１３】
【発明の実施の形態】
以下、本発明による電池の装着構造の実施の形態を説明する。
【００１４】
図４に示すように、絶縁監視端末装置１の背面には図示しない蓋が設けられており、この蓋を空けた位置には電池収納部２が設けられている。
【００１５】
電池収納部２に収納する電池６としては、リチウム電池（２ＣＲ５）が用いられる。図１，２に示すように、電池６には一対の端子９が設けられている。夫々の端子９は平板をＬ字形に曲げたものであり、電池６の上面と背面との２面に跨って取り付けられている。
【００１６】
電池収納部２の構造を図１に示す。図のように、絶縁監視端末装置１の容器を構成するケース３には、電池６を嵌め込む保持部４が形成されている。保持部４はケース３と一体の側板４ａ，４ｂと、下面板４ｃと、背面板４ｄとによって構成されている。保持部４には、保持部４に押し込んだ電池６を背面板４ｄへ向かって押圧する押圧部５ａ，５ｂが形成されている。即ち、側板４ａの上下端には側板４ａと一体に一対の押圧部５ａが形成され、側板４ｂの上下端には側板４ｂと一体に一対の押圧部５ｂが形成されている。押圧部５ａ，５ｂは保持部４へ向かって電池６を抱き込むように、図１（ａ）のように断面形状にアールが形成されている。押圧部５ａ，５ｂはケース３と一体に形成されており、ケース３は弾性部材としての樹脂で形成されているので、押圧部５ａ，５ｂは外力を加えると弾性変形し、外力を除去すると元の状態に復元しようとする。押圧部５ａ，５ｂは、弾性部材の復元しようとする性質を利用し、電池６を保持部４へ常時押圧するものである。
【００１７】
電池６を保持部４へ入れると同時に電池６への電気的な接続が行なわれるようにするために、一対のバネ端子（接続導体）７が設けられる。バネ端子７はプリント板（電源需要部）８と電池６とを接続するものであり、その構成を図３に示す。図３（ｃ）に示すように、バネ端子７は略Ｃ字形に形成されており、電池６の端子９に接触させる接触部７ａと、導体部７ｂ，７ｃと、プリント板８に接続させるために２又に分かれた一対の接続部７ｄとから構成される。接触部７ａの幅寸法は、導体部７ｂ，７ｃの幅方向の両側を切り欠いた略１／３の大きさであり、導体部７ｂとのなす角度θは１００〜１２０度が好ましく、本実施の形態ではθ＝１２０度となっている。バネ端子７は、図１のように背面板４ｄを切り欠いて形成した一対の切欠部１１に収容した状態で、プリント板８に形成した孔１０に一対の接続部７ｄを挿入してハンダ付けされている。一対の切欠部１１は、電池６を保持部４に嵌め込んだ時に、電池６の一対の端子９と対応する位置に配置されている。
【００１８】
保持部４に電池６が保持されていない状態では、図２に示すようにバネ端子７の接触部７ａの先端はやや左方へ突出した状態にある。電池６を保持部４に入れるには、図１の２組の押圧部５ａ，５ｂを外側へ押し開くように変形させて、電池６を押し込む。電池６が保持部４に入ると、弾性部材で形成された押圧部５ａ，５ｂには、変形後の復元力が働き、電池６は保持部４へ押圧される。このため、電池６の一対の端子９がバネ端子７の接触部７ａを押圧し、図１（ｃ）に示すように、接触部７ａは導体部７ｂと略直角になる。この状態では接触部７ａが復元しようとして付勢力が常時加わっており、接触部７ａは端子９に常時付勢された状態となり、電池６とバネ端子７との通電が確保される。つまり、保持部４での電池６の機械的な保持作用が押圧部５ａ，５ｂによって行なわれ、電池６の電気的な接続作用が端子９への接触部７ａの常時付勢によって行なわれる。
【００１９】
保持部４からの電池６の取り出しは、押圧部５ａ，５ｂの付勢力に抗して電池６を引き出すことによって行なわれる。
【００２０】
なお、電源需要部としてはプリント板に限らず、電源を必要とする部分であればどこでもよい。
【００２１】
【発明の効果】
以上の説明からわかるように、本発明による電池の装着構造によれば、電池を保持する保持部と、当該保持部へ向かって電池を押圧する押圧部と、該押圧部によって押圧された電池の端子の部分が押圧されると共に電源需要部に直接に結合された接続導体とを有し、前記押圧部が電池を前記接続導体に常時押圧するようにしたので、電池から電源需要部までの接続に対して、従来のようなリード線やコネクタ等の接続用の部品が不要となってコストダウンが図れるだけでなく、押圧部が電池の端子の部分を接続導体に常時押圧することから、電池と接続導体との通電が確保される。

As shown in FIG. 1A, the pressing portions 5 a and 5 b are formed in a round shape so as to embrace the battery 6 toward the holding portion 4. The pressing portions 5a and 5b are formed integrally with the case 3, and the case 3 is formed of a resin as an elastic member. Therefore, the pressing portions 5a and 5b are elastically deformed when an external force is applied, and are restored when the external force is removed. Try to restore to the state of. The pressing portions 5a and 5b always press the battery 6 against the holding portion 4 by utilizing the property of the elastic member to be restored.
[0017]
A pair of spring terminals (connection conductors) 7 are provided so that the battery 6 is inserted into the holding portion 4 and at the same time is electrically connected to the battery 6. The spring terminal 7 connects the printed board (power supply unit) 8 and the battery 6, and the configuration is shown in FIG. As shown in FIG. 3C, the spring terminal 7 is formed in a substantially C-shape, and is connected to the contact portion 7a for contacting the terminal 9 of the battery 6, the conductor portions 7b and 7c, and the printed board 8. And a pair of connecting portions 7d divided into two. The width dimension of the contact portion 7a is approximately 1/3 of the width of the conductor portions 7b and 7c cut off on both sides in the width direction, and the angle θ formed with the conductor portion 7b is preferably 100 to 120 degrees. In the embodiment, θ = 120 degrees. The spring terminal 7 is soldered by inserting a pair of connecting portions 7d into holes 10 formed in the printed board 8 in a state of being housed in a pair of cutouts 11 formed by cutting the back plate 4d as shown in FIG. Have been. The pair of cutouts 11 are arranged at positions corresponding to the pair of terminals 9 of the battery 6 when the battery 6 is fitted into the holding unit 4.
[0018]
In a state where the battery 6 is not held in the holding portion 4, the tip of the contact portion 7a of the spring terminal 7 is in a state of slightly projecting leftward as shown in FIG. In order to insert the battery 6 into the holding portion 4, the two sets of pressing portions 5a and 5b in FIG. 1 are deformed so as to be pushed outward, and the battery 6 is pushed in. When the battery 6 enters the holding portion 4, a restoring force after deformation acts on the pressing portions 5 a and 5 b formed of the elastic member, and the battery 6 is pressed against the holding portion 4. Therefore, the pair of terminals 9 of the battery 6 press the contact portions 7a of the spring terminals 7, and the contact portions 7a are substantially perpendicular to the conductor portions 7b as shown in FIG. In this state, the urging force is constantly applied to the contact portion 7a in an attempt to restore it, and the contact portion 7a is constantly urged to the terminal 9, so that the power supply between the battery 6 and the spring terminal 7 is ensured. That is, the mechanical holding action of the battery 6 in the holding section 4 is performed by the pressing sections 5 a and 5 b, and the electrical connecting action of the battery 6 is performed by constantly biasing the contact section 7 a to the terminal 9.
[0019]
The removal of the battery 6 from the holding portion 4 is performed by pulling out the battery 6 against the urging force of the pressing portions 5a and 5b.
[0020]
The power supply demanding unit is not limited to a printed board, but may be any unit that requires a power supply.
