Description

サーミスタの取付け構造Mounting structure of the thermistor
　本発明は、サーミスタの取付け構造に関し、詳しくは、複数の蓄電素子が並べられてなる蓄電素子群に取り付けられるサーミスタの取付け構造に関する。 The present invention relates to a mounting structure of a thermistor, and more particularly to a mounting structure of a thermistor mounted on a storage element group in which a plurality of storage elements are arranged.
　電気自動車やハイブリッド車用の電池モジュールにおいては、出力を大きくするために複数の単電池（蓄電素子）が横並びに接続されている。隣り合う蓄電素子の電極端子間はバスバーなどの接続部材で接続することにより複数の蓄電素子が直列や並列に接続されるようになっている。 In a battery module for an electric car or a hybrid car, a plurality of single cells (storage elements) are connected side by side in order to increase the output. A plurality of storage elements are connected in series or in parallel by connecting the electrode terminals of adjacent storage elements with a connecting member such as a bus bar.
　ところで、電池モジュールを高温状態で使用すると寿命が低下することがあり、リチウムイオン電池などを複数個接続してなる電池モジュールでは、充電の際に高温になることにより発火する虞がある。そこで、このような事態を避けるべく、電池モジュールには電池温度を検知するための温度センサ（サーミスタ）が取り付けられる（例えば特許文献１を参照）。特許文献１においては、サーミスタの取付構造として、サーミスタの係止アーム部を絶縁樹脂製のケース本体部の係止部に係止して、サーミスタを電池の上面に密着する技術が開示されている。 When the battery module is used in a high temperature state, the life may be reduced, and in a battery module formed by connecting a plurality of lithium ion batteries etc., there is a possibility that the battery may catch fire when it is heated. Therefore, in order to avoid such a situation, a temperature sensor (thermistor) for detecting the battery temperature is attached to the battery module (see, for example, Patent Document 1). Patent Document 1 discloses, as a mounting structure of a thermistor, a technology for locking a thermistor to a top surface of a battery by locking a locking arm of the thermistor to a locking portion of a case main body made of insulating resin. .
特開２０１３－１５７１２３号公報JP, 2013-157123, A
　しかしながら、絶縁樹脂製のケース本体部は機械的や温度等のストレスによって変形しやすい。ケース本体部が変形すると、サーミスタの電池への密着（取付け）の安定性が失われることとなる。そのため、機械的や温度等のストレスに対して、簡易な構造によって、サーミスタを蓄電素子により安定して取付けできるサーミスタの取付け構造が所望されていた。 However, the case main body made of insulating resin is easily deformed by mechanical stress or stress such as temperature. If the case body is deformed, the stability of the attachment (attachment) of the thermistor to the battery will be lost. Therefore, there has been a demand for a mounting structure of the thermistor which can stably mount the thermistor by the storage element with a simple structure against mechanical stress or temperature stress.
　そこで、本明細書では、簡易な構造によって、サーミスタを蓄電素子により安定して取付けできるサーミスタの取付け構造を提供する。 So, in this specification, the attachment structure of the thermistor which can attach a thermistor stably by an electrical storage element with a simple structure is provided.
　本明細書によって開示されるサーミスタの取付け構造は、正極および負極の電極端子を有する複数の蓄電素子が並べられてなる蓄電素子群に取り付けられるサーミスタの取付け構造であって、前記複数の蓄電素子の隣接する蓄電素子の正極および負極の電極端子を接続するバスバーであって、前記サーミスタを取付けるための係止部を有するバスバーと、前記蓄電素子群に取付けられ、前記バスバーを保持するバスバー保持部と、復元力によって前記サーミスタを前記蓄電素子の表面に押圧する弾性押圧部材であって、一端部が前記サーミスタに固定され、他端部が前記バスバーの係止部に係止する弾性押圧部材と、を備える。
　本構成によれば、サーミスタが、単に、一端部がサーミスタに固定され、他端部がバスバーの係止部に係止する弾性押圧部材によって、蓄電素子の表面に押圧されて蓄電素子群に取り付けられる。バスバーは、通常、金属製であり、絶縁樹脂製と比べて剛性が強く、変形しにくい。そのため、サーミスタの取付け構造によれば、簡易な構造によって、サーミスタを蓄電素子により安定して取付けできる。 The mounting structure of the thermistor disclosed by the present specification is a mounting structure of a thermistor mounted on a storage element group in which a plurality of storage elements having positive and negative electrode terminals are arranged, and the mounting structure of the plurality of storage elements A bus bar connecting the positive and negative electrode terminals of the adjacent storage element, the bus bar having a locking portion for mounting the thermistor; and a bus bar holding portion mounted on the storage element group and holding the bus bar An elastic pressing member pressing the thermistor against the surface of the storage element by a restoring force, wherein one end is fixed to the thermistor and the other end is locked to the locking portion of the bus bar; Equipped with
According to this configuration, the thermistor is simply pressed against the surface of the storage element by the elastic pressing member whose one end is fixed to the thermistor and the other end is locked to the locking portion of the bus bar and attached to the storage element group Be The bus bars are usually made of metal, and are more rigid and less deformed than those made of insulating resin. Therefore, according to the mounting structure of the thermistor, the thermistor can be stably mounted by the storage element with a simple structure.
　上記サーミスタの取付け構造において、前記バスバーは、前記電極端子に接続される接続板部と、前記バスバーの幅方向の一端縁から延設された延設板部と、を含み、前記係止部は前記延設板部に形成されており、前記サーミスタは、前記延設板部と前記蓄電素子の表面との間の空間に配置されているようにしてもよい。
　本構成によれば、バスバーにサーミスタ用の延設板部が設けられることによって、バスバーの幅が拡がる。それによって、バスバーの板厚を変更せずにバスバーの断面積を拡げることができる。その結果、板厚を厚くして断面積を拡げる場合と比べて放熱性がよく、バスバーの温度上昇を抑制して、大電流に対応できる。また、延設板部によるバスバーの幅の増大に伴って形成される蓄電素子との間の空間を有効利用できる。 In the thermistor mounting structure, the bus bar includes a connection plate portion connected to the electrode terminal, and an extending plate portion extended from one end edge of the bus bar in the width direction, and the locking portion is The extension plate portion may be formed, and the thermistor may be disposed in a space between the extension plate portion and the surface of the storage element.
According to this configuration, the width of the bus bar is expanded by providing the extension plate portion for the thermistor on the bus bar. Thereby, the cross-sectional area of the bus bar can be expanded without changing the thickness of the bus bar. As a result, compared with the case where the plate thickness is increased to expand the cross-sectional area, the heat dissipation is good, and the temperature rise of the bus bar can be suppressed to cope with the large current. Further, the space between the storage element and the storage element formed with the increase in the width of the bus bar by the extended plate portion can be effectively used.
　また、上記サーミスタの取付け構造において、前記サーミスタは、絶縁樹脂によってモールド形成されており、前記弾性押圧部材の一端部は、前記サーミスタの絶縁樹脂内にモールドされているようにしてもよい。
　本構成によれば、弾性押圧部材の一端部がサーミスタにモールドされ、サーミスタと一体化されている。そのため、弾性押圧部材の一端部をサーミスへ固定する構成が簡易に実現できる。 In the mounting structure of the thermistor, the thermistor may be molded with an insulating resin, and one end of the elastic pressing member may be molded in the insulating resin of the thermistor.
According to this configuration, one end of the elastic pressing member is molded to the thermistor and integrated with the thermistor. Therefore, the structure which fixes the one end part of an elastic press member to a thermistor can be implement | achieved simply.
　また、上記サーミスタの取付け構造において、前記係止部は、前記弾性押圧部材の他端部が挿入されて係止される係止孔を含むようにしてもよい。
　本構成によれば、弾性押圧部材の他端部を係止孔に挿入することで、簡単な構成によって、弾性押圧部材の他端部を係止し、バスバーに固定することができる。 Further, in the thermistor mounting structure, the locking portion may include a locking hole into which the other end of the elastic pressing member is inserted and locked.
According to this configuration, by inserting the other end of the elastic pressing member into the locking hole, the other end of the elastic pressing member can be locked and fixed to the bus bar by a simple configuration.
　また、上記サーミスタの取付け構造において、前記弾性押圧部材は、金属製板バネによって構成されているようにしてもよい。 Further, in the above-mentioned mounting structure of the thermistor, the elastic pressing member may be configured by a metal plate spring.
　本構成によれば、弾性押圧部材を簡易な構成によって実現できる。 According to this configuration, the elastic pressing member can be realized by a simple configuration.
　本発明のサーミスタの取付け構造によれば、簡易な構造によって、サーミスタを蓄電素子により安定して取付けできる。 According to the mounting structure of the thermistor of the present invention, the thermistor can be stably mounted by the storage element with a simple structure.

　４．サーミスタの取付け方法
　次に、サーミスタ３０の取付け方法について説明する。サーミスタ３０は、接続モジュール２０が蓄電素子群１０に組付けられる際に、蓄電素子１１の上面に取付けられる。 4. Next, a method of mounting the thermistor 30 will be described. The thermistor 30 is attached to the upper surface of the storage element 11 when the connection module 20 is assembled to the storage element group 10.
　すなわち、バスバー保持部２２の各バスバー保持ユニット２３にバスバー２１を取り付ける。その際、一個のバスバー２１に対して、金属製板バネ３２の他端部３２Ｂを係止させる。具体的には、金属製板バネ３２の先端部３２Ｃを、バスバー２１の係止孔２１Ｃを介してバスバー２１の切り欠き部２１Ｄに係止させる。そして、このようにバスバー２１が保持されたバスバー保持部２２、すなわち、接続モジュール２０を蓄電素子群１０の各蓄電素子１１の電極端子１４が形成された面に組付ける際、蓄電素子群１０の一端から順に、例えば図２の矢印Ｘ方向の左端から順に、各電極端子１４をバスバー２１の端子挿通孔２１Ｈに挿通させる。 That is, the bus bars 21 are attached to the bus bar holding units 23 of the bus bar holding portion 22. At that time, the other end 32 B of the metal plate spring 32 is locked to one bus bar 21. Specifically, the tip end portion 32C of the metal plate spring 32 is engaged with the notch 21D of the bus bar 21 via the engagement hole 21C of the bus bar 21. When the bus bar holding portion 22 in which the bus bar 21 is held in this way, that is, the connection module 20 is assembled to the surface on which the electrode terminal 14 of each storage element 11 of the storage element group 10 is formed, Each electrode terminal 14 is inserted into the terminal insertion hole 21H of the bus bar 21 sequentially from one end, for example, sequentially from the left end in the arrow X direction in FIG.
　次いで、各電極端子１４にナットを取り付けることによって、接続モジュール２０を蓄電素子群１０に組付けることができる。その際、サーミスタ３０が係止されたバスバー２１に関しては、金属製板バネ３２の復元力によって、サーミスタ本体部３１の底部が蓄電素子１１の上面に押圧されて密着されるように、バスバー２１を電極端子１４にナット締めする。その際、サーミスタ３０は、図６に示されるように、バスバー２１の延設板部２１Ｂと蓄電素子の上面（表面）１２との間の空間に配置される。 Subsequently, the connection module 20 can be assembled to the storage element group 10 by attaching a nut to each electrode terminal 14. At that time, regarding the bus bar 21 in which the thermistor 30 is locked, the bus bar 21 is pressed so that the bottom portion of the thermistor main body 31 is pressed against the upper surface of the storage element 11 by the restoring force of the metal plate spring 32. Tighten the nut on the electrode terminal 14. At that time, as shown in FIG. 6, the thermistor 30 is disposed in the space between the extended plate portion 21B of the bus bar 21 and the upper surface (surface) 12 of the storage element.
　５．本実施形態の効果
　サーミスタ３０が、単に、一端部３２Ａがサーミスタ３０に固定され、他端部３２Ｂがバスバー２１の係止部（２１Ｃ、２１Ｄ）に係止する金属製板バネ（弾性押圧部材）３２によって、１つの蓄電素子１１の表面１２に押圧されて蓄電素子群１０に取り付けられる。バスバー２１は、通常、金属製であり、絶縁樹脂製と比べて剛性が強く、変形しにくい。そのため、本実施形態のサーミスタの取付け構造によれば、簡易な構造によって、サーミスタ３０を蓄電素子１１により安定して取付けできる。 5. Effects of the present embodiment A metal plate spring (elastic pressing member) in which one end 32A of the thermistor 30 is simply fixed to the thermistor 30, and the other end 32B is locked to the locking portion (21C, 21D) of the bus bar 21. 32 is attached to the storage element group 10 by being pressed against the surface 12 of one storage element 11. The bus bar 21 is usually made of metal, has higher rigidity than that of insulating resin, and is not easily deformed. Therefore, according to the attachment structure of the thermistor of the present embodiment, the thermistor 30 can be stably attached to the storage element 11 with a simple structure.
　また、バスバー２１にサーミスタ用の延設板部２１Ｂが設けられることによって、バスバー２１の幅が拡がる。それによって、バスバー２１の板厚を変更せずにバスバー２１の断面積を拡げることができる。その結果、板厚を厚くして断面積を拡げる場合と比べて放熱性がよく、バスバー２１の温度上昇を抑制して、大電流に対応できる。また、延設板部２１Ｂによるバスバーの幅の増大に伴って形成される、バスバー２１と蓄電素子１１との間の空間を有効利用できる。 Further, by providing the extension plate portion 21B for the thermistor on the bus bar 21, the width of the bus bar 21 is expanded. Thereby, the cross-sectional area of the bus bar 21 can be expanded without changing the thickness of the bus bar 21. As a result, the heat dissipation is good as compared with the case where the plate thickness is increased to expand the cross-sectional area, and the temperature rise of the bus bar 21 can be suppressed to cope with a large current. In addition, the space between the bus bar 21 and the storage element 11 which is formed along with the increase in the width of the bus bar by the extended plate portion 21B can be effectively used.
　また、金属製板バネの一端部３２Ａがサーミスタ３０内にモールドされ、サーミスタ３０と一体化されている。そのため、金属製板バネの一端部３２Ａをサーミスタ３０へ固定する構成が簡易に実現できる。 Further, one end 32 A of a metal plate spring is molded in the thermistor 30 and integrated with the thermistor 30. Therefore, the configuration for fixing the one end 32A of the metal plate spring to the thermistor 30 can be easily realized.
　また、金属製板バネの他端部３２Ｂを係止孔２１Ｃに挿入することで、簡単な構成によって、金属製板バネの他端部３２Ｂを係止し、バスバー２１に固定することができる。
　また、弾性押圧部材は、金属製板バネ３２によって構成されているため、
弾性押圧部材を簡易な構成によって実現できる。なお、弾性押圧部材は、金属製板バネ３２に限られない。 Further, by inserting the other end 32B of the metal plate spring into the locking hole 21C, the other end 32B of the metal plate spring can be locked and fixed to the bus bar 21 with a simple configuration.
Further, since the elastic pressing member is constituted by the metal plate spring 32,
The elastic pressing member can be realized by a simple configuration. The elastic pressing member is not limited to the metal plate spring 32.
