電池収納装置に関連する先行技術文献としては次のようなものがある。 Prior art documents related to the battery storage device include the following.
図６は従来より一般に使用されている従来例の要部構成説明図、図７は図６の要部構成説明図で、図６の矢印Ａ
より見た図である。
図において、電池収納ケース１は、ケース本体２とカバー３とを有する。
電池収納ケース１には、電池４，５が収納されている。
この場合は、単１電池が使用されている。
FIG. 6 is a diagram illustrating the configuration of the main part of a conventional example that is generally used, and FIG. 7 is a diagram illustrating the configuration of the main part of FIG.
FIG.
In the figure, the battery storage case 1 has a case body 2 and a cover 3.
Batteries 4 and 5 are stored in the battery storage case 1.
In this case, a single battery is used.
電池４と電池５とが、端子６と円錐コイルばね端子７を経由して直列に接続され、プレート端子８と円錐コイルばね端子９を有する回路基板１１を介してコネクタ部１２，１３より電力供給を行う。
電池４，５のプラス極側の端子が、ばね性のない固定端子６，８であり、電池４，５のマイナス極側の端子が円錐コイルばね７，９で構成されている。
The battery 4 and the battery 5 are connected in series via the terminal 6 and the conical coil spring terminal 7, and power is supplied from the connector parts 12 and 13 via the circuit board 11 having the plate terminal 8 and the conical coil spring terminal 9. I do.
The terminals on the positive pole side of the batteries 4 and 5 are fixed terminals 6 and 8 having no spring property, and the terminals on the negative pole side of the batteries 4 and 5 are constituted by conical coil springs 7 and 9.
このような装置においては、以下の間題点がある。
電池４，５と端子間の瞬断時に、電気容量を確保するコンデンサを有することが防爆規格上許されない電池収納装置においては、振動のない静止状態では、電池４，５のマイナス極側の端子が円錐コイルばね７，９のため、ばね力により電池４，５と端子間の瞬断及び接触不良は起きない。
Such an apparatus has the following problems.
In a battery housing device that does not allow a capacitor to ensure electric capacity at the time of a momentary disconnection between the batteries 4 and 5 and the terminal, the terminal on the negative pole side of the batteries 4 and 5 in a stationary state without vibration However, the conical coil springs 7 and 9 do not cause a momentary disconnection or poor contact between the batteries 4 and 5 and the terminals due to the spring force.
しかし、振動状態では、電池４，５のプラス極側の端子が、ばね性のない固定端子６，８のため電池４，５と端子間の瞬断及び接触不良が振動加速度により発生し、振動状態での、例えば、無線通信機器等のエラーを引き起こしてしまう。 However, in the vibration state, the terminals on the positive pole side of the batteries 4 and 5 are fixed terminals 6 and 8 having no spring property, so that momentary interruption and poor contact between the batteries 4 and 5 and the terminals occur due to vibration acceleration, and vibrations occur. For example, an error of a wireless communication device or the like is caused in the state.
図６において、振動状態での電池４，５と端子間の瞬断及び接触不良を解決するためには、電池単体質量約１００（ｇ）に対して、５０倍のばね押さえ力５０（Ｎ）が必要となるが、使用する電池の許容押さえ力は２０（Ｎ）のため、その仕様を満たすことができない。また荷重が大きいためその組立作業性が問題となる。 In FIG. 6, in order to solve the instantaneous disconnection and poor contact between the batteries 4 and 5 and the terminals in the vibration state, the spring pressing force 50 (N) which is 50 times the mass of the battery alone is about 100 (g). However, since the allowable holding force of the battery used is 20 (N), the specification cannot be satisfied. Moreover, since the load is large, the assembly workability becomes a problem.
電池４，５を誤挿入(逆挿し)した状態で、たとえば、無線通信形差圧伝送器に使用すると、電池４，５のプラス極と端子のマイナス極７，９の接触(通電)と電池のマイナス極と端子のプラス極６，８の接触(通電)のため、電池に過電流が発生し、電池の異常発熱や液洩れが生じる故障を引き起こしてしまう。 When the batteries 4 and 5 are erroneously inserted (reversely inserted), for example, when used in a wireless communication type differential pressure transmitter, the contact (energization) between the positive poles of the batteries 4 and 5 and the negative poles 7 and 9 of the terminals and the battery As a result of contact (energization) between the negative pole of the terminal and the positive poles 6 and 8 of the terminal, an overcurrent is generated in the battery, resulting in a malfunction that causes abnormal heat generation and leakage of the battery.
本発明の目的は、上記の課題を解決するもので、振動状態においても、瞬断及び接触不良を起こさない、電池収納装置を提供することにある。
また、電池の許容押さえ力を満たし、その組立作業性も良好な電池収納装置を提供することにある。
また、電池を誤挿入しても、電池に過電流が発生せず、電池の異常発熱や液洩れが生じない電池収納装置を提供することにある。
An object of the present invention is to solve the above-described problems, and to provide a battery storage device that does not cause instantaneous interruption and contact failure even in a vibration state.
Another object of the present invention is to provide a battery storage device that satisfies the allowable holding force of the battery and has good assembly workability.
It is another object of the present invention to provide a battery storage device that does not cause overcurrent in the battery even if the battery is erroneously inserted, and does not cause abnormal heat generation or leakage of the battery.
