【考案の詳細な説明】
この考案は自動車用交流発電機の出力端子の改良に関す
る。[Detailed Description of the Invention] This invention relates to an improvement in the output terminal of an automotive alternator.
この種出力端子の従来は第１図、第２図に示すものであ
った。Conventional output terminals of this type are shown in FIGS. 1 and 2.
図に於て、１は交流発電機のブラケットリヤ、２は一対
のヒートシンク、３は三相ブリッジ回路を構成する６個
のダイオードで、それぞれ一対のヒートシンク２に半田
付けされている。In the figure, 1 is the bracket rear of the alternator, 2 is a pair of heat sinks, and 3 is six diodes constituting a three-phase bridge circuit, each of which is soldered to the pair of heat sinks 2.
４はこれらダイオード３を接続する３本のリード線、５
は出力端子ボルトで、■側のヒートシンク２に固着され
ている。4 are three lead wires connecting these diodes 3, 5
is an output terminal bolt, which is fixed to the heat sink 2 on the ■ side.
５ａはヒートシンク２の上面に当接する出力端子ボルト
５の頭部、５ｂはヒートシンク２に対し回しめするため
のナール部、５ｃはねじ部である。5a is the head of the output terminal bolt 5 that comes into contact with the upper surface of the heat sink 2, 5b is a knurled portion for turning the heat sink 2, and 5c is a threaded portion.
この出力端子ボルト５はブラケットリア１に一対の絶縁
物６を介し、ワッシャとナツト７により固定される。This output terminal bolt 5 is fixed to the bracket rear 1 via a pair of insulators 6 with a washer and a nut 7.
８は図示しない自動車のバッテリの■端子に接続するた
めのリード線の端子で、出力端子ボルト５に嵌入された
状態でナツト９により締付けられ固定される。Reference numeral 8 denotes a terminal of a lead wire for connection to a terminal (3) of an automobile battery (not shown), which is fitted into the output terminal bolt 5 and fixed by being tightened with a nut 9.
さて、この例に於て、出力端子ボルト５はそのナール部
５ｂを通じてヒートシンク２に固着され、そしてこのヒ
ートシンク２は出力端子ボルト５が絶縁物６を介在して
ブラケットリア１にナツト７により締付けられることに
より固定される。Now, in this example, the output terminal bolt 5 is fixed to the heat sink 2 through its knurled portion 5b, and the output terminal bolt 5 is fastened to the bracket rear 1 with a nut 7 with an insulator 6 interposed between the heat sink 2. It is fixed by this.
而して、端子８を出力端子ボルト５の先端部に嵌入しこ
のボルト５のねじ部５ｃにナツト９を締付ければ端子８
は各ナツト７．９により挾持されて固定される。Then, by inserting the terminal 8 into the tip of the output terminal bolt 5 and tightening the nut 9 on the threaded portion 5c of the bolt 5, the terminal 8 is removed.
is clamped and fixed by each nut 7.9.
然るに、各ナツト７．９は同径で同じサイズのものが使
用され、しかもそれぞれの接触面積が等しく同一トルク
でもって締付けられるため交流発電機の保守点検のため
に機関からの取外しに際し、端子８を取外くべくナツト
９を緩め方向に回すとナツト７が端子８と共に緩むこと
が多々あった。However, since each nut 7.9 has the same diameter and size, and each nut has the same contact area and is tightened with the same torque, when removing the alternator from the engine for maintenance inspection, the terminal 8. When the nut 9 was turned in the loosening direction to remove it, the nut 7 often came loose together with the terminal 8.
従って、第３図に示す通りナツト７が少し緩んだ状態で
ナツト９のみを出力端子ボルト５から取外し端子８を取
外した後、再び交流発電機を取付け、そして端子８を取
付ける時ナツト７の緩みに気付かずにナツト９を締付け
ると端子８は固定されるが出力端子ボルト５はナツト７
の緩みより固定できず、同時にヒートシンク２も固定で
きないことになる。Therefore, as shown in Fig. 3, when the nut 7 is slightly loosened, only the nut 9 is removed from the output terminal bolt 5, the terminal 8 is removed, the alternator is reinstalled, and when the terminal 8 is installed, the nut 7 is loosened. If you tighten the nut 9 without noticing, the terminal 8 will be fixed, but the output terminal bolt 5 will be tightened by the nut 7.
It cannot be fixed due to the looseness of the heat sink 2, and at the same time, the heat sink 2 cannot be fixed either.
従って、出力端子ボルト５及びヒートシンク２がブラケ
ットリア１に固定されていない状態で自動車が走行すれ
ば機関の振動等により出力端子ボルト５及びヒートシン
ク２がガタつき他の○側部品に接触したり、遂にはナツ
ト７゜９が緩んで脱落すると端子８が出力端子ボルト５
から外れそして他の○側部品に接触すればバッテリは短
絡されて損傷腰またスパークの発生により火災を誘発す
る等非常に危険である。Therefore, if the car runs while the output terminal bolt 5 and heat sink 2 are not fixed to the bracket rear 1, the output terminal bolt 5 and heat sink 2 may rattle due to engine vibrations and come into contact with other O-side parts. When the nut 7゜9 finally loosens and falls off, the terminal 8 is connected to the output terminal bolt 5.
If the battery comes off and comes into contact with other parts on the ○ side, the battery will be short-circuited, causing damage or causing sparks, which is extremely dangerous.
この考案は上記欠点を解消するもので、出力端子ボルト
に所定サイズの第１ねじ部とこの第１ねじ部に連なって
第２ねじ部を形成しこれら第１１第２ねじ部にそれぞれ
ナツトを締付けて共線することにより第２ねじ部に締付
けられたナツトのみを緩めても第１ねじ部に締付けられ
たナツトが共回りして緩められることのないようにした
自動車交流発電機の出力端子にある。This invention solves the above-mentioned drawbacks by forming a first threaded part of a predetermined size on the output terminal bolt and a second threaded part connected to the first threaded part, and tightening nuts on these eleventh and second threaded parts. The output terminal of an automobile alternator is designed such that even if only the nut tightened on the second threaded portion is loosened, the nut tightened on the first threaded portion does not rotate together and become loosened. be.
以下、第４図第５図に示す実施例について詳述する。The embodiments shown in FIGS. 4 and 5 will be described in detail below.
図に於て、１０は出力端子ボルトで、頭部１０ａと、ナ
ール部１０ｂと、所定サイズ、例えばＭ６の第１ねじ部
１０ｃとこの第１ねじ部１０Ｃに段部を介して連なりＭ
６よりは小さいＭ５の第２ねじ部１０ｄとからなる。In the figure, 10 is an output terminal bolt, which has a head 10a, a knurled portion 10b, a first threaded portion 10c of a predetermined size, for example, M6, and is connected to the first threaded portion 10C via a stepped portion.
It consists of a second threaded portion 10d of M5 smaller than 6.
言うに及ばないことであるが第１ねじ部１０ｃの外径は
第２ねじ部１０ｄのそれより大きい。Needless to say, the outer diameter of the first threaded portion 10c is larger than that of the second threaded portion 10d.
１１は第１ねじ部１０ｃに締付けられる第１ナツトであ
るＭ６のナツト、１２は第２ねじ部１０ｄに締付けられ
る第２ナツトであるＭ５のナツトでその外径はナツト１
１のそれよりも小さいものである。Reference numeral 11 denotes an M6 nut, which is a first nut to be tightened on the first threaded portion 10c, and 12 is an M5 nut, which is a second nut that is tightened on the second threaded portion 10d, and its outer diameter is the same as that of the nut 1.
It is smaller than that of 1.
さて、出力端子ボルト１０はブラケットリア１にヒート
シンク２を固定するべく一対の絶縁物６を介して第１ね
じ部１０ｃにナツト１１を締付ける。Now, in order to fix the heat sink 2 to the bracket rear 1, the output terminal bolt 10 is tightened with a nut 11 on the first threaded portion 10c via a pair of insulators 6.
而して、出力端子ボルト１０の段部付近に端子８を嵌入
腰そして第２ねじ部１０ｄにナツト１２を締付けて端子
８を固定する。Then, the terminal 8 is fitted into the vicinity of the stepped portion of the output terminal bolt 10, and the nut 12 is tightened to the second threaded portion 10d to fix the terminal 8.
ここで、各ナツト１１．１２の締付はトルクは異ならせ
るものでナツト１１の方がナツト１２よりも締付トルク
は大きい。Here, each nut 11, 12 is tightened with different torques, and the tightening torque of nut 11 is greater than that of nut 12.
しかも、座面々積はナツト１１の方がナツト１２よりは
大きく、そのためナツト１１とワッシャとの当接面積は
このナツト１１とワッシャ及び端子８を介Ｉ７て当接す
るナツト１２の当接面積よりは大きい。Moreover, the bearing area of the nut 11 is larger than that of the nut 12, so the contact area between the nut 11 and the washer is larger than the contact area of the nut 12, which contacts the nut 11 through the washer and terminal 8 via I7. big.
以上のように構成すれば交流発電機の保守点検時等にナ
ツト１２のみを緩めたとしても、上述したナツト１１．
１２の外径の違い、ピッチの違い、及び座面々積の違い
等によりナツト１２の緩みトルクがナツト１１のそれよ
りは小さいことによりナツト１２の緩めによりナツト１
１が緩むことは全くなくなる。With the above configuration, even if only the nut 12 is loosened during maintenance and inspection of the alternator, the aforementioned nut 11.
The loosening torque of the nut 12 is smaller than that of the nut 11 due to the difference in the outer diameter of the nut 12, the difference in the pitch, and the difference in the seat area.
1 will no longer come loose.
尚、上述の実施例以外に種々の変形が可能である。Note that various modifications other than the above-described embodiments are possible.
例えば第１第２ねじ部１０ｃ、１０ｄのピッチを同一に
したり、また各ナツト１１．１２の外径を同一にするこ
とも考えられ、更に第１第２ねじ部１０ｃ、１０ｄを同
一径にしてそのピッチのみを変えることも考えられる。For example, it is possible to make the pitch of the first and second threaded parts 10c and 10d the same, or to make the outer diameter of each nut 11.12 the same, and furthermore, to make the first and second threaded parts 10c and 10d the same diameter. It is also possible to change only the pitch.
要はナツト１２の緩めトルクをナツト１１の緩めトルク
より小さくなる関係に構成すればよいのである。The point is that the loosening torque of the nut 12 should be configured to be smaller than the loosening torque of the nut 11.
