Thereby, the direct contact with the battery 10 and the floor surface F is suppressed.

＜端子部の接続検知＞
図４、図６を参照し、端子部３２は、バッテリ側端子部１２との接続時、ベース部材３５の先端をバッテリ側端子部１２のベース部材１５の先端に当接させる。両端子部１２，３２のベース部材１５，３５の先端は、両端子部１２，３２同士の接続時に互いに接触する接触部１７，３７とされている。これらの接触部１７，３７は、両端子部１２，３２同士の接続時に脱落防止機構３６が固定（締結）されると、互いに押圧し合う。これらの接触部１７，３７の少なくとも一方（例えば端子部３２の接触部３７）には、互いの接触状態（押圧状態）を検知する接触センサ３８を備えている。接触センサ３８は、例えば押圧荷重を検出する荷重センサである。制御部２６は、接触センサ３８の検知情報に基づき、脱落防止機構３６が固定状態にあると判断したとき、バッテリ１０の充電制御を許可する。接触センサ３８がバッテリ側端子部１２に備えられる場合、接触センサ３８の検知情報は、例えばＢＭＵ１８を介して制御部２６に送信される。 <Terminal connection detection>
With reference to FIGS. 4 and 6, the terminal portion 32 causes the tip of the base member 35 to abut the tip of the base member 15 of the battery side terminal portion 12 when connected to the battery side terminal portion 12. The tips of the base members 15 and 35 of the both terminal portions 12 and 32 are contact portions 17 and 37 that contact each other when the both terminal portions 12 and 32 are connected to each other. These contact portions 17 and 37 are pressed against each other when the drop-off prevention mechanism 36 is fixed (fastened) when the two terminal portions 12 and 32 are connected to each other. At least one of these contact portions 17 and 37 (for example, the contact portion 37 of the terminal portion 32) is provided with a contact sensor 38 that detects the mutual contact state (pressed state). The contact sensor 38 is a load sensor that detects a pressing load, for example. When the control unit 26 determines that the dropout prevention mechanism 36 is in a fixed state based on the detection information of the contact sensor 38, the control unit 26 permits the charging control of the battery 10. When the contact sensor 38 is provided in the battery side terminal part 12, the detection information of the contact sensor 38 is transmitted to the control part 26 via BMU18, for example.

In this case, the contact state of the drop-off prevention mechanism 36 can be accurately detected by the contact sensor 38 provided in the contact portion 37. On the other hand, the contact portions 17 and 37 and the contact sensor 38 may be provided in a portion separated from the bolt member 34 and the nut member 14 as in a range A between the pair of bolt members 34 shown in FIG.

ボルト部材３４は、例えばスナップリング３４ａ等によりベース部材３５からの抜け止めがなされている。両端子部１２，３２の接続時、テーパ状の誘導部１４ｄがスナップリング３４ａを避けている（図６参照）。なお、ボルト部材３４は、抜け止めを有さず端子部３２から抜き差し自在であってもよい。   The bolt member 34 is prevented from coming off from the base member 35 by, for example, a snap ring 34a. When the two terminal portions 12 and 32 are connected, the tapered guide portion 14d avoids the snap ring 34a (see FIG. 6). The bolt member 34 may be freely inserted and removed from the terminal portion 32 without having a retaining member.

端子部３２の接続検知の変形例として、ベース部材３５におけるボルト部材３４の頭部３４ｂが接する座面（締結座面）４１に、頭部３４ｂの接触圧からボルト部材３４の締結状態を検知する締結センサ４２を備えてもよい。この場合、制御部２６は、締結センサ４２の検知情報に基づき、脱落防止機構３６が固定状態にあると判断したとき、バッテリ１０の充電制御を許可する。   As a modified example of the connection detection of the terminal portion 32, the fastening state of the bolt member 34 is detected from the contact pressure of the head portion 34b on the seat surface (fastening seat surface) 41 with which the head portion 34b of the bolt member 34 contacts the base member 35. A fastening sensor 42 may be provided. In this case, when the control unit 26 determines that the dropout prevention mechanism 36 is in the fixed state based on the detection information of the fastening sensor 42, the control unit 26 permits the charging control of the battery 10.

端子部３２の接続検知の他の変形例として、バッテリ側端子部１２のベース部材１５におけるナット部材１４のナット穴１４ａ内（例えば奥端）に、ボルト部材３４が規定深さまで螺合したことを検知する螺合センサ４４を備えてもよい。この場合、制御部２６は、螺合センサ４４の検知情報に基づき、脱落防止機構３６が固定状態にあると判断したとき、バッテリ１０の充電制御を許可する。螺合センサ４４の検知情報は、例えばＢＭＵ１８を介して制御部２６に送信される。   As another modified example of the connection detection of the terminal part 32, the bolt member 34 is screwed into the nut hole 14a (for example, the back end) of the nut member 14 in the base member 15 of the battery side terminal part 12 to a specified depth. You may provide the screwing sensor 44 to detect. In this case, the control unit 26 permits the charging control of the battery 10 when determining that the dropout prevention mechanism 36 is in the fixed state based on the detection information of the screwing sensor 44. Detection information of the screwing sensor 44 is transmitted to the control unit 26 via, for example, the BMU 18.

なお、上記した各センサ３８，４２，４４の少なくとも一つにより端子部３２の接続検知を行う構成であればよい。また、各センサ３８，４２，４４の何れかを組み合わせて端子部３２の接続検知を行う構成でもよい。   In addition, what is necessary is just the structure which detects the connection of the terminal part 32 by at least one of each above-mentioned sensors 38,42,44. Moreover, the structure which detects the connection of the terminal part 32 combining any of each sensor 38,42,44 may be sufficient.

＜作用＞
次に、本実施形態の作用について説明する。
図３を参照し、バッテリ充電器２０は、電源コード２３のプラグ２３ａを商用交流電源のコンセントＣに接続し、かつ充電コード２４の端子部３２をバッテリ１０に接続することで、バッテリ充電制御を開始する。バッテリ１０を床面Ｆに載置する際には、端子部３２に備えるバッテリ載置部３９のマット３９ａを引き出して予め床面Ｆに敷いておく。これにより、重量物であるバッテリ１０を床面Ｆ上に載置する際の衝撃が抑えられ、バッテリ１０および床面Ｆの傷つき等が抑えられる。 <Action>
Next, the operation of this embodiment will be described.
Referring to FIG. 3, the battery charger 20 performs battery charging control by connecting the plug 23 a of the power cord 23 to the outlet C of the commercial AC power source and connecting the terminal portion 32 of the charging cord 24 to the battery 10. Start. When the battery 10 is placed on the floor surface F, the mat 39a of the battery placement portion 39 provided in the terminal portion 32 is pulled out and laid on the floor surface F in advance. Thereby, the impact at the time of mounting the heavy battery 10 on the floor surface F is suppressed, and the damage of the battery 10 and the floor surface F, etc. are suppressed.

図４を参照し、端子部３２をバッテリ１０に接続する際、まず、端子部３２をバッテリ側端子部１２に差し込み方向で対向配置する。その後、図５に示すように、端子部３２のボルト部材３４を、バッテリ側端子部１２のナット部材１４のナット穴１４ａ内（案内部１４ｃ内）に挿通する。このとき、ナット穴１４ａの開口縁部にテーパ状の誘導部１４ｄが形成されているので、ボルト部材３４のナット穴１４ａへの挿入が容易である。   Referring to FIG. 4, when connecting the terminal portion 32 to the battery 10, first, the terminal portion 32 is disposed opposite to the battery-side terminal portion 12 in the insertion direction. Thereafter, as shown in FIG. 5, the bolt member 34 of the terminal portion 32 is inserted into the nut hole 14 a (inside the guide portion 14 c) of the nut member 14 of the battery side terminal portion 12. At this time, since the tapered guide portion 14d is formed at the opening edge of the nut hole 14a, the bolt member 34 can be easily inserted into the nut hole 14a.

ボルト部材３４をナット穴１４ａの案内部１４ｃに沿って挿通することで、端子部３２がバッテリ側端子部１２への差し込み方向に沿って案内される。これにより、端子部３２が差し込み方向と交差する方向にずれたり差し込み方向に対して傾いたりすることが抑止される。ボルト部材３４をナット穴１４ａの雌ネジ部１４ｂに螺合する直前まで挿入すると、端子部３２の複数の端子本体３３がバッテリ側端子部１２の複数の端子本体１３にそれぞれ容易かつ正確に対向配置された状態となる。
この状態で、図６に示すように、ボルト部材３４を雌ネジ部１４ｂに締め込むことで、複数の端子本体１３，３３同士が互いに干渉することなく確実に篏合接続される。 By inserting the bolt member 34 along the guide portion 14c of the nut hole 14a, the terminal portion 32 is guided along the insertion direction into the battery-side terminal portion 12. Thereby, it is suppressed that the terminal part 32 shift | deviates to the direction which cross | intersects the insertion direction, or inclines with respect to the insertion direction. When the bolt member 34 is inserted until just before being screwed into the female screw portion 14b of the nut hole 14a, the plurality of terminal bodies 33 of the terminal portion 32 are arranged to easily and accurately face the plurality of terminal bodies 13 of the battery side terminal portion 12, respectively. It will be in the state.
In this state, as shown in FIG. 6, by tightening the bolt member 34 into the female screw portion 14b, the plurality of terminal bodies 13 and 33 are securely connected together without interfering with each other.

ボルト部材３４がナット部材１４に締め込まれることで、脱落防止機構３６が両端子部１２，３２を接続状態に固定する。このとき、接触センサ３８が両端子部１２，３２の接触部１７，３７同士の接触状態（押圧状態）を検知する。この検知情報に基づき、制御部２６がバッテリ１０の充電制御を許可してバッテリ充電制御を開始する。脱落防止機構３６の固定により両端子部１２，３２が確実に接続された後に、バッテリ充電制御が開始されるので、電力線や通信線の接続不良が抑えられ、安全かつ確実にバッテリ１０の充電がなされる。また、バッテリ１０の充電時における充電コード２４への足掛かり等により、端子部３２が意図せず外れることが防止され、安全性および確実性がさらに高められる。   When the bolt member 34 is tightened into the nut member 14, the drop-off prevention mechanism 36 fixes both the terminal portions 12 and 32 to the connected state. At this time, the contact sensor 38 detects a contact state (pressed state) between the contact portions 17 and 37 of the both terminal portions 12 and 32. Based on this detection information, the control unit 26 permits charging control of the battery 10 and starts battery charging control. Since the battery charge control is started after the terminal portions 12 and 32 are securely connected by fixing the drop-off prevention mechanism 36, the connection failure of the power line and the communication line is suppressed, and the battery 10 can be charged safely and reliably. Made. Further, the terminal portion 32 is prevented from unintentionally coming off due to a foothold on the charging cord 24 when the battery 10 is charged, and safety and reliability are further improved.
