FIG.

図９および図１０において、充電台２１の載置部２１ａに掃除機本体１の後面を接地させるようにして収納載置させる。このとき、掃除機本体１が載置部２１ａに接近するにつれて、図１１に矢示するように、掃除機本体１の後下面に設けたシャッター開閉操作当接部９が、シャッター開閉操作部２５を軸２６を中心に徐々に回動させる。図１２に示すように、シャッター開閉操作部２５と同軸で構成されているシャッター２４も回動して充電端子開口部２３が開口し、略角筒状の本体端子収納部８が充電端子収納部２２の充電端子開口部２３内に挿入される。  9 and 10, the mountingportion 21a of the chargingbase 21 is housed and placed so that the rear surface of thecleaner body 1 is grounded. At this time, as thecleaner body 1 approaches the mountingportion 21a, the shutter opening / closingoperation contact portion 9 provided on the rear lower surface of thecleaner body 1 is moved to the shutter opening /closing operation portion 25 as shown by an arrow in FIG.

FIG.

図１３及び図１４に示すように、充電台２１の充電端子２７は、充電端子収納部２２の略中心位置に配設され、銅合金製で、先端側を略平板状に形成している。  As shown in FIGS. 13 and 14, the chargingterminal 27 of the chargingstand 21 is disposed at a substantially central position of the chargingterminal housing portion 22, is made of a copper alloy, and has a distal end formed in a substantially flat plate shape.

本体端子収納部８は、充電端子収納部２２よりも少許幅狭に形成されており、本体端子収納部８の開口部８ａは、本体端子収納部８が充電端子収納部２２の一側に偏って挿入された場合でも、充電端子２７が挿入可能な大きさに形成されている。本体端子１０は、銅合金製で、一対の端子部を有するクリップ状に形成されており、端子部間隔を狭めた充電端子２７との接触部の下方を漸次広がる形状に形成している。  The main bodyterminal storage portion 8 is formed to be slightly narrower than the chargingterminal storage portion 22, and theopening portion 8 a of the main bodyterminal storage portion 8 is biased toward the chargingterminal storage portion 22. Even when inserted, the chargingterminal 27 is formed in such a size that it can be inserted. Themain body terminal 10 is made of a copper alloy, is formed in a clip shape having a pair of terminal portions, and is formed in a shape that gradually expands below the contact portion with the chargingterminal 27 whose terminal portion interval is narrowed.

図１３は、シャッター２４が開いて充電端子開口部２３を開口させ、略角筒状の本体端子収納部８が充電端子収納部２２内に挿入され始めた状態を示している。  FIG. 13 shows a state in which theshutter 24 is opened to open the chargingterminal opening 23, and the substantially rectangular tube-shaped main bodyterminal storage portion 8 starts to be inserted into the chargingterminal storage portion 22.

本体端子収納部８の開口部８ａ側には、開口部８ａ内面側壁面との間に微小な隙間を設けて水平運動可能な一対のシャッターＢ３２が配設されており、シャッターＢ３２は、板バネ３１の先端３１ａによりシャッターＢ３２の相対向する先端部を当接させて開口部８ａを閉じるようにバネ付勢している。シャッターＢ３２の相対向する先端部分には、シャッターＢ３２を開放する開放機構として、先端部分になるに従って外側から内側に傾斜する傾斜部３２ａが形成されており、傾斜部３２ａに充電端子２７の先端が接触すると、図１４に示すように、シャッターＢ３２を傾斜部３２ａに沿わせて水平方向に移動させ、充電端子２７が本体端子１０の位置に到達し接続することとなる。シャッターＢ３２は、充電端子２７の挿入操作時に、シャッター押さえ３０により本体端子収納部８内側への移動を阻止している。  On the side of theopening 8a of the main bodyterminal accommodating portion 8, a pair of shutters B32 that can move horizontally with a minute gap between theopening 8a and the side wall surface of the inner surface of theopening 8a are disposed. The front end 31a of theshutter 31 abuts the opposing front end of the shutter B32 so as to close theopening 8a. As the opening mechanism for opening the shutter B32, aninclined portion 32a that inclines from the outside toward the inside is formed at the opposite tip portions of the shutter B32, and the tip of the chargingterminal 27 is formed on theinclined portion 32a. When contact is made, as shown in FIG. 14, the shutter B32 is moved in the horizontal direction along theinclined portion 32a, and the chargingterminal 27 reaches the position of themain body terminal 10 to be connected. When the chargingterminal 27 is inserted, theshutter B 32 is prevented from moving inward of the main bodyterminal housing portion 8 by theshutter press 30.

本体端子１０は、一対の端子部を有するクリップ状に形成し、端子部間隔を狭めた接触部の下方を漸次広がる形状に形成しているので、充電端子２７と確実に電気的に接続でき、接触不良を低減できる。また、本体端子１０は、一対の端子部を有しているので、充電端子２７と２箇所で電気的に接続でき、接触不良をより低減できる。さらに、本体端子１０は、一対の端子部を有しているので、本体端子収納部８が充電端子収納部２２の一側に偏って挿入された場合でも、充電端子２７が本体端子１０の一方の端子部に電気的に接続し、二次電池への充電を可能とすることができる。  Themain body terminal 10 is formed in a clip shape having a pair of terminal portions, and is formed in a shape that gradually expands below the contact portion with a narrowed interval between the terminal portions, so that it can be reliably electrically connected to the chargingterminal 27, Contact failure can be reduced. Moreover, since themain body terminal 10 has a pair of terminal portions, it can be electrically connected to the chargingterminal 27 at two locations, and contact failure can be further reduced. Furthermore, since themain body terminal 10 has a pair of terminal portions, even when the main bodyterminal storage portion 8 is inserted to be biased to one side of the chargingterminal storage portion 22, the chargingterminal 27 is one of themain body terminals 10. It is possible to charge the secondary battery electrically.

以上のように、充電端子２７が本体端子収納部８の開口部８ａから挿入されて充電台２１の充電端子２７と本体端子１０が接続することとなる。  As described above, the chargingterminal 27 is inserted from theopening 8a of the main bodyterminal storage portion 8, and the chargingterminal 27 of the chargingbase 21 and themain body terminal 10 are connected.
