【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.
