【考案の詳細な説明】
本考案はコロイド式鉛蓄電池やケースとカバー
でパツクされたアルカリ蓄電池の通電端子に関す

保守、大電流が流せる事などから、ポータブル電
子機器の電源として最近広く使用されてきてい
る。[Detailed Description of the Invention] The present invention relates to a current-carrying terminal for a colloidal lead-acid battery or an alkaline storage battery packed with a case and a cover. This type of storage battery has recently been widely used as a power source for portable electronic devices because it is non-directional, requires no maintenance, and can carry large currents.
一般にこの種の蓄電池の通電端子は、ナイロン
プラグや圧着式の端子板を使用している。しかし
最近では、機器に電池を内蔵し、電池の端子と機
器の端子との接続をスムーズにするために、電池
ケース等から金属製の平板を端子として引出し、
機器端子側の金属弾性を利用してこれにスライド
圧着し、ワンタツチで電池の挿入と端子の接続と
を行なう傾向にある。 Generally, the current-carrying terminals of this type of storage battery use nylon plugs or crimp-type terminal plates. However, recently, devices have built-in batteries, and in order to make the connection between the battery terminals and the device terminals smooth, metal flat plates are pulled out as terminals from the battery case, etc.
There is a tendency to use the elasticity of the metal on the terminal side of the device to slide and crimp it onto the device terminal, allowing one-touch insertion of the battery and connection of the terminal.
本考案は、このような電池の通電端子の改良に
関するものであり、通電端子をバイメタルで構成
したことを特徴とするものである。以下、その実
施例を図面により説明する。 The present invention relates to an improvement of the current-carrying terminal of such a battery, and is characterized in that the current-carrying terminal is made of bimetal. Examples thereof will be described below with reference to the drawings.
図中１はその一部が電池カバー２ａから外部へ
突出した通電端子であり、２ｂは電池ケース、３
はカバー２ａに一体形成された通電端子の固定用
突起、４は端子と接続されたリード線である。 In the figure, 1 is a current-carrying terminal, a part of which protrudes from the battery cover 2a, 2b is a battery case, and 3
Reference numeral 4 indicates a fixing protrusion for a current-carrying terminal formed integrally with the cover 2a, and 4 indicates a lead wire connected to the terminal.
この種の電池は機器に対する電池の脱着回数が
増加するにつれて通電端子１の弾性劣化や変形が
生じ、機器側端子との接触不良を起こすことがあ
る。この防止対策として、機器側端子との圧着強
度を当初から高めておくことがとれらているが、
その場合には機器に対する電池の脱着抵抗が大き
くなり、簡単に電池を取り替えるということが難
しくなる。 In this type of battery, as the number of times the battery is attached to and removed from the device increases, the elasticity of the current-carrying terminal 1 deteriorates and deforms, which may cause poor contact with the terminal on the device side. As a preventive measure, the strength of the crimping with the device terminals has been increased from the beginning.
In that case, the resistance to attaching and detaching the battery to the device increases, making it difficult to easily replace the battery.
そこで、本考案では通電端子１をバイメタルで
構成し、ポータブル機器５の機器側端子６に対す
る初期脱着抵抗を第３図の如く小さくして電池の
装着をスムーズに行ない、通電端子１に電流が流
れると、その際のジユール熱によりバイメタルが
機器側端子６方向へ第４図に示す端子の折曲げ部
７を支点として１′の如く曲がろうとして機器側
端子６との圧着強度を強くし確実な端子間の接触
を保つようにした。また機器側への通電を停止す
れば端子は１′の状態から１の状態に復帰し、電
池の機器からの離脱をスムーズに行なうことがで
きる。以上のように通電端子にバイメタルを用い
た本考案では端子に通電されると端子が反り返つ
て機器側端子との圧着強度を増し接触不良を長期
間にわたり防止できるという特長がある。 Therefore, in the present invention, the current-carrying terminal 1 is made of bimetal, and the initial attachment/detachment resistance to the device-side terminal 6 of the portable device 5 is made small as shown in Figure 3, so that the battery can be installed smoothly, and current flows through the current-carrying terminal 1. At that time, due to the Joule heat, the bimetal tries to bend in the direction of the device side terminal 6 using the bent part 7 of the terminal as a fulcrum as shown in 1' as shown in Fig. 4, thereby increasing the crimp strength with the device side terminal 6 and ensuring a secure connection. The contact between the terminals was maintained. Furthermore, when the power supply to the device is stopped, the terminal returns from the state 1' to the state 1, and the battery can be smoothly removed from the device. As described above, the present invention, which uses bimetal for the current-carrying terminal, has the advantage that when the terminal is energized, the terminal bends back, increasing the strength of the crimp with the terminal on the device side, and preventing poor contact for a long period of time.
また、バイメタルからなる端子を通電時の発熱
で外側へ反り返らせる他、電池内側へ反り返らせ
る構造としてもよく、その場合には充電時の異常
発熱や短絡時に端子が電池内側へ反り返つて充電
回路や機器への電力供給回路が自動的に開かれ、
通電を遮断するため、異常発熱に基づく電池の変
形や破裂等を防止できる利点もある。 In addition to warping outwards due to the heat generated by the bimetal terminals when electricity is applied, a structure may also be used in which the terminals are warped toward the inside of the battery. The charging circuit and the power supply circuit to the device are automatically opened,
Since electricity is cut off, it also has the advantage of preventing deformation and explosion of the battery due to abnormal heat generation.
