Description

本発明は、複数の単電池を備えた電池モジュールに関する。   The present invention relates to a battery module including a plurality of single cells.

従来、電気的に接続された複数の単電池を備えた電池モジュールとして、特許文献1に記載のものが知られている。各単電池は正極、及び負極からなる電極端子を備える。複数の単電池は、一の単電池の電極端子と、他の単電池の逆極性の電極端子と、が金属製のバスバーによって直列に接続されている。   Conventionally, a battery module described in Patent Document 1 is known as a battery module including a plurality of electrically connected single cells. Each unit cell includes an electrode terminal including a positive electrode and a negative electrode. In the plurality of unit cells, the electrode terminal of one unit cell and the electrode terminal having the opposite polarity of the other unit cell are connected in series by a metal bus bar.

バスバーには一対の貫通孔が形成されている。この貫通孔内に、一の単電池の電極端子と、他の単電池の逆極性の電極端子と、が挿通されて、各電極端子にナットが螺合されることにより、一の単電池の電極端子と、他の単電池の逆極性の電極端子と、が電気的に接続されている。   A pair of through holes are formed in the bus bar.

特開2011−8957号公報JP 2011-8957 A

しかしながら上記の構成によると、バスバーの貫通孔内に電極端子を挿通させる作業において、作業者は電極端子に直接に触る恐れがある。更に、電極端子にナットを螺合させる作業において、作業者は、電極端子及びバスバーの少なくとも一方に直接に触る恐れがある。   However, according to said structure, in the operation | work which inserts an electrode terminal in the through-hole of a bus-bar, an operator has a possibility of touching an electrode terminal directly. Furthermore, in the operation of screwing the nut onto the electrode terminal, the operator may directly touch at least one of the electrode terminal and the bus bar.

上記したように、複数の単電池が直列に接続された状態では、電極端子、及びバスバーには比較的に高い電圧の電流が流れる。このため、電極端子とバスバーとを接続する作業中に、作業者が、電極端子、又はバスバー等の電流が流れる部材に対して直接に触る状況が発生することはできるだけ回避したい。   As described above, when a plurality of single cells are connected in series, a relatively high voltage current flows through the electrode terminals and the bus bar. For this reason, it is desired to avoid as much as possible the situation where the operator directly touches the electrode terminal or the member through which a current flows, such as the bus bar, during the operation of connecting the electrode terminal and the bus bar.

本発明は上記のような事情に基づいて完成されたものであって、単電池同士を電気的に接続する作業において、作業者が、電流が流れる部材に対して直接に接触することを抑制する技術を提供することを目的とする。   The present invention has been completed based on the above circumstances, and suppresses the operator from directly contacting a member through which a current flows in an operation of electrically connecting the cells.

Since the conductor side terminal is connected to the electrode terminal of the unit cell, one unit cell and the other unit cell among the plurality of unit cells are electrically connected to the conductor side terminal and the relay terminal. Is a single cell, an electrode terminal of one single cell, a conductor and conductor side terminal connected to the electrode terminal of one single cell, a relay terminal, a conductor side terminal connected to the electrode terminal of another single cell, and Electrical connection is made in the order of the conductor, the electrode terminal of the other unit cell, and the other unit cell.

本発明によれば、導体の外周は絶縁被覆で覆われている。また、導体側端子は絶縁性の合成樹脂からなるコネクタハウジングに収容されている。更に、中継端子は、絶縁性の合成樹脂からなる中継コネクタハウジングの奥壁に埋設されて、両端部がフード部内に配されている。このように、電流が流れる部材は絶縁性の材料で覆われているので、単電池同士を電気的に接続する作業が実行される際に、作業者が、電流が流れる部材に対して直接に触れることを抑制できる。   According to the present invention, the outer periphery of the conductor is covered with the insulating coating. The conductor side terminal is accommodated in a connector housing made of an insulating synthetic resin. Further, the relay terminal is embedded in the back wall of the relay connector housing made of insulating synthetic resin, and both end portions are arranged in the hood portion.

(本実施形態の組み付け工程)
続いて、本実施形態の組み付け工程の一例を示す。本実施形態の組み付け工程は以下の記載に限定されない。
(Assembly process of this embodiment)
Then, an example of the assembly | attachment process of this embodiment is shown. The assembly process of this embodiment is not limited to the following description.

まず、複数の単電池11を、所定の方向に並べる。このとき、隣り合う電極端子12の極性が逆になるように単電池11を配する。   First, the plurality of single cells 11 are arranged in a predetermined direction. At this time, the cells 11 are arranged so that the polarities of the adjacent electrode terminals 12 are reversed.

次いで、作業者は、複数の単電池11のうち、一の単電池11の電極端子12に接続された導体13、又はこの導体13の他方の端部に接続された導体側端子15が収容されたコネクタハウジング18を持って、中継コネクタハウジング26の一方のフード部23内に、コネクタハウジング18を嵌合させる。すると、導体側端子15と、中継端子16とが電気的に接続される。   Next, the worker accommodates the conductor 13 connected to the electrode terminal 12 of one unit cell 11 among the plurality of unit cells 11, or the conductor side terminal 15 connected to the other end of the conductor 13. Holding the connector housing 18, the connector housing 18 is fitted into one hood portion 23 of the relay connector housing 26. Then, the conductor side terminal 15 and the relay terminal 16 are electrically connected.

次いで、作業者は、複数の単電池11のうち、一の単電池11の隣に並べられて、一の単電池11の電極端子12とは逆極性を有する他の単電池11の電極端子12に接続された導体13、又はこの導体13に他方の端部に接続された導体側端子15が収容されたコネクタハウジング18を持って、中継コネクタハウジング26の他方のフード部23内に、コネクタハウジング18を嵌合させる。すると、導体側端子15と、中継端子16とが電気的に接続される。   Next, the worker arranges the one of the plurality of unit cells 11 next to the one unit cell 11 and has the electrode terminal 12 of the other unit cell 11 having the opposite polarity to the electrode terminal 12 of the one unit cell 11. A connector housing 18 in which the conductor 13 connected to the conductor 13 or the conductor-side terminal 15 connected to the other end of the conductor 13 is accommodated in the other hood portion 23 of the relay connector housing 26. 18 is fitted. Then, the conductor side terminal 15 and the relay terminal 16 are electrically connected.

Thereby, even when the positions of the electrode terminals 12 of the adjacent unit cells 11 are shifted due to the assembly tolerance of the plurality of unit cells 11, the operator can easily connect the connector housing 18 by bending the conductor 13. It can be fitted into the hood part 23.

上記の作業を繰り返すことにより、複数の単電池11が直列に接続され、電池モジュール10が形成される。   By repeating the above operation, the plurality of single cells 11 are connected in series, and the battery module 10 is formed.

(本実施形態の作用、効果)

(Operation and effect of this embodiment)
Then, the effect | action and effect of this embodiment are demonstrated. According to the present embodiment, the conductor side terminal 15 and the relay terminal 16 are electrically connected by fitting the connector housing 18 to the hood portion 23 of the relay connector housing 26. Since the conductor 13 tool side terminal is connected to the electrode terminal 12 of the unit cell 11, the conductor side terminal 15 and the relay terminal 16 are electrically connected, so that one unit among the plurality of unit cells 11 is connected. The battery 11 and other unit cells 11 include one unit cell 11, an electrode terminal 12 of the one unit cell 11, a conductor 13 and a conductor side terminal 15 connected to the electrode terminal 12 of the one unit cell 11, and a relay terminal. 16, the conductor side terminal 15 and the conductor 13 connected to the electrode terminal 12 of the other unit cell 11, the electrode terminal 12 of the other unit cell 11, and the other unit cell 11 are electrically connected in this order.

そして、本実施形態によれば、導体13の外周は絶縁被覆14で覆われている。また、導体側端子15は絶縁性の合成樹脂からなるコネクタハウジング18に収容されている。更に、中継端子16は、絶縁性の合成樹脂からなる中継コネクタハウジング26の奥壁24に埋設されて、両端部がフード部23内に配されている。このように、電流が流れる部材は絶縁性の材料で覆われているので、単電池11同士を電気的に接続する作業が実行される際に、作業者が、電流が流れる部材に対して直接に触れることを抑制できる。   According to this embodiment, the outer periphery of the conductor 13 is covered with the insulating coating 14. The conductor side terminal 15 is accommodated in a connector housing 18 made of an insulating synthetic resin. Further, the relay terminal 16 is embedded in the back wall 24 of the relay connector housing 26 made of an insulating synthetic resin, and both end portions are arranged in the hood portion 23. Thus, since the member through which the current flows is covered with an insulating material, when the operation of electrically connecting the unit cells 11 is performed, the operator directly applies to the member through which the current flows. Touching can be suppressed.

また、本実施形態によれば、導体13は可撓性を有する。これにより、導体13を撓ませることにより、単電池11同士の組み立て公差を吸収することができる。これは、単電池11の個数が多い場合には特に効果的である。   Moreover, according to this embodiment, the conductor 13 has flexibility. Thereby, the bending tolerance of the single cells 11 can be absorbed by bending the conductor 13. This is particularly effective when the number of unit cells 11 is large.
