Description

本発明は、組電池に関し、特に、複数の鉛蓄電池間を電気的に接続する導電板を覆う電気絶縁カバーを装着した組電池に関する。   The present invention relates to an assembled battery, and more particularly, to an assembled battery equipped with an electrically insulating cover that covers a conductive plate that electrically connects a plurality of lead-acid batteries.

組電池は、複数の電池を直列あるいは並列に電気的接続することにより、高出力・高容量とするものであり、鉛蓄電池、リチウムイオン電池等を用いたものが多く利用されている。中でも、再生可能エネルギーを利用する風力発電、太陽光発電等のシステムには、鉛蓄電池を用いた組電池を利用することが多い。
組電池は、要求される出力電圧、容量等毎に、個々の電池を直列あるいは並列に組合せて、導電板により電気的に接続することにより作製される。鉛蓄電池を用いて組電池を作製する場合、鉛蓄電池間の電気的接続には導電板として銅板を用いることが多く、隣接する鉛蓄電池の端子間に渡した銅板を、ボルト・ナット、かしめ、溶接等の手段を用いて端子に固定し電気的接続を行う。
通常、導電板は安全確保のために絶縁カバーで覆われているが、鉛蓄電池の電圧、電流値等を測定する際には、測定子を当接するために導電板を露出させる必要がある。特許文献１（特開２０１０−５５８８２）には、測定・点検作業を容易にするために絶縁カバーに測定子挿入用の開口を設けることが記載されている。
また、特許文献２（特開２００８−１６６００８）には、絶縁カバー自体をヒンジにより開閉できるようにし、導電板を被覆状態と１／３ないし全体の広い領域の露出状態とに変更可能にした絶縁カバーが記載されている。 The assembled battery has a high output and a high capacity by electrically connecting a plurality of batteries in series or in parallel, and a battery using a lead storage battery, a lithium ion battery, or the like is often used. In particular, an assembled battery using a lead storage battery is often used for a system such as wind power generation or solar power generation using renewable energy.
The assembled battery is manufactured by combining individual batteries in series or in parallel for each required output voltage, capacity, etc., and electrically connecting them with a conductive plate. When producing an assembled battery using a lead storage battery, a copper plate is often used as a conductive plate for electrical connection between the lead storage batteries, and the copper plate passed between the terminals of the adjacent lead storage batteries is bolted, nuts, caulked, It fixes to a terminal using means, such as welding, and electrical connection is performed.
Normally, the conductive plate is covered with an insulating cover for ensuring safety. However, when measuring the voltage, current value, etc. of the lead storage battery, it is necessary to expose the conductive plate in order to abut the measuring element. Patent Document 1 (Japanese Patent Laid-Open No. 2010-55882) describes that an opening for inserting a probe is provided in an insulating cover in order to facilitate measurement / inspection work.
Further, in Patent Document 2 (Japanese Patent Laid-Open No. 2008-166008), the insulating cover itself can be opened and closed by a hinge so that the conductive plate can be changed between a covered state and an exposed state of 1/3 to the entire wide area. A cover is described.

しかしながら、特許文献１では、開口が常時開放された状態にあるため、作業者の指や器物が誤って開口に挿入され、導電板に接触することで感電・短絡の心配がある。
また、特許文献２では、導電板を露出状態にしたとき、導電板全面あるいは、導電板の１／３程度が露出状態となり、同様に感電・短絡の心配がある。
本発明は、隣接する鉛蓄電池の端子間に渡した導電板を絶縁カバーで覆った組電池において、測定・点検作業を容易にすると共に不用意に導電板に接触することがないよう安全性を高めることを目的とする。 However, in Patent Document 1, since the opening is always open, there is a risk of an electric shock or a short circuit due to the operator's finger or object being erroneously inserted into the opening and contacting the conductive plate.
Further, in Patent Document 2, when the conductive plate is exposed, the entire surface of the conductive plate or about 1/3 of the conductive plate is exposed, and there is a concern of electric shock and short circuit.
In the assembled battery in which the conductive plate passed between the terminals of adjacent lead storage batteries is covered with an insulating cover, the measurement and inspection work is facilitated and safety is prevented so that the conductive plate is not inadvertently contacted. The purpose is to increase.

本発明は、以下のものに関する。
（１）複数の鉛蓄電池の端子間を電気的に接続する導電板と、前記導電板に装着され少なくとも導電板の表の面と周囲端面を覆う電気絶縁カバーを備え、前記電気絶縁カバーが、導電板の表の面の任意の部位を露出する開口を有し、この開口を開閉する被覆体を備えたことに特徴を有する。
（２）項（１）において、被覆体が弾力性を有し、絶縁カバーの開口に対し着脱自在であることに特徴を有する。
（３）項（１）において、被覆体が、絶縁カバーの開口を開閉する被覆部と、この被覆部を絶縁カバーに連結させる、弾性を有した接続部とを備え、前記被覆部が通常時において開口を閉塞する状態を保持する機能を有することに特徴を有する。 The present invention relates to the following.
(1) A conductive plate that electrically connects terminals of a plurality of lead storage batteries, and an electric insulating cover that is attached to the conductive plate and covers at least a front surface and a peripheral end surface of the conductive plate, the electric insulating cover includes: It has an opening that exposes an arbitrary portion of the front surface of the conductive plate, and is characterized by having a covering that opens and closes the opening.
(2) Item (1) is characterized in that the covering has elasticity and is detachable from the opening of the insulating cover.
(3) In the item (1), the covering includes a covering portion that opens and closes an opening of the insulating cover, and an elastic connecting portion that connects the covering portion to the insulating cover, and the covering portion is in a normal state. It has the characteristic in having the function to hold | maintain the state which obstruct | occludes opening.

本発明によれば、導電板を覆う絶縁カバーは、開口を有し、必要に応じて電池の点検作業を行うことができると共に、前記絶縁カバーが、開口を閉塞する被覆体を備えていることから、点検時を除く通常時において、被覆部を用いて開口を閉塞することにより、開口から誤って導電板に接触して発生する感電・短絡の心配を減らすことができる。
特に前記被覆体が、絶縁カバーに連結される弾性を有した接続部を備え、点検時を除く通常時において、開口を弾発的に閉塞する状態を保持する機能を備える場合、点検後、接続部の弾性により意識することなく開口を閉塞することができ、開口の塞ぎ忘れが起こらないことにより安全性が更に高くなる。 According to the present invention, the insulating cover that covers the conductive plate has an opening, and the battery can be inspected as necessary, and the insulating cover includes a covering that closes the opening. Therefore, in normal times except during inspection, the opening is closed using the covering portion, so that it is possible to reduce the fear of electric shocks and short circuits that occur due to erroneous contact with the conductive plate from the opening.
In particular, when the covering includes a connecting portion having elasticity connected to the insulating cover and has a function of holding the state of elastically closing the opening in a normal time except for the inspection, the connection is made after the inspection. The opening can be closed without being conscious of the elasticity of the portion, and the safety is further enhanced by not forgetting to close the opening.

It is preferable that By doing so, the covering portion 9 can elastically close the opening 8 of the insulating cover 6 by the elasticity of the connecting portion after the measurement is finished without being particularly conscious of it, and without forgetting to close the opening 8. Safety is improved.
The function of elastically closing the opening 8 by the covering portion 9 at normal times is to process a synthetic resin or rubber having rubber elasticity, for example, so that the connecting portion 10 has a U-shaped spring structure. Can be realized.

その結果、実施例１では、図３に示すように、被覆部を取り外すのみで導電板の限定された小領域を露出させ点検を実施できるので、極めて短い時間で点検可能であり、点検時以外に導電板に接触する危険性は少ない。
比較例１では、点検時に絶縁カバー自体を取り外す必要があることから、取り外し作業に多くの時間を要すると共に、導電板が全て露出することから、導電板に不用意に接触しないよう慎重な作業が必要であった。 <Time required for battery check>
The battery conditions in the battery state were compared between the assembled battery shown in Example 1 and the assembled battery shown in Comparative Example 1.
As a result, in Example 1, as shown in FIG. 3, it is possible to perform inspection by exposing a limited small area of the conductive plate only by removing the covering portion. There is little risk of contact with the conductive plate.
In Comparative Example 1, since it is necessary to remove the insulating cover itself at the time of inspection, it takes a lot of time for the removal work and all the conductive plate is exposed. It was necessary.
