本案は、内燃機関の点火装置に係り、特に磁石を利用し
た無接点式配電器に関するものである。[Detailed Description of the Invention] The present invention relates to an ignition device for an internal combustion engine, and particularly to a non-contact power distributor using a magnet.
第1図および第2図は従来の無接点式配電器の一例を示
し、第1図は平面図、第2図は要部縦断面図である。FIGS. 1 and 2 show an example of a conventional non-contact type power distributor, with FIG. 1 being a plan view and FIG. 2 being a longitudinal cross-sectional view of the main part.

6の継手ピン7と連結している。A joint 3 of a negative pressure response device 2 attached to the power distribution housing 1 is connected to a joint pin 7 of a movable base 6 rotatably provided via a steel ball 8 to a fixed base 5 fixed to the housing 1. ing.
一方可動ベース6上には、磁石板9、ステータコア10

イル17に電圧が発生し、点火時期が決定される。On the other hand, a shaft 11 driven by an engine via a gear 4
A pair of reluctors 13 having protrusions 131 corresponding to the number of cylinders of the engine are attached to the rotor shaft 12 which is loosely fitted into the rotor shaft 12 . 101, reluctor 13
The amount of magnetic flux passing through the rotor shaft 12 and the movable base 6 as a magnetic path changes, and a voltage is generated in the detection coil 17 annularly surrounding the rotor shaft 12, thereby determining the ignition timing.
ここで、磁石板9の一面例えば可動ベース6に接する面
をN極とするかS極にするかは、検出コイル17の巻方
向および点火時期制御ユニット16内の回路接続関係等
の諸条件から決定される。Here, whether one surface of the magnet plate 9, for example, the surface in contact with the movable base 6, should be the north pole or the south pole depends on various conditions such as the winding direction of the detection coil 17 and the circuit connection within the ignition timing control unit 16. It is determined.

際に磁石板9の表裏を誤って裏返しに可動ベース6に取
付けてしまう場合がある。Fig. 3.4.5 shows a single unit diagram of the stator core 10 and the magnet plate 9. As mentioned above, the magnet plate 9, the stator core 10, and the movable base 6 are placed in symmetrical positions with the appropriate tightening screws 14, 15 or tightly fixed with caulking rivets, etc., but due to the symmetry of the fixed position, it is possible that the magnetic plate 9 may be attached to the movable base 6 with the front and back sides of the magnet upside down during assembly work of the device. be.
この場合には機関始動しない欠陥製品となる。In this case, the product will be defective and will not start the engine.
上記のような磁石板9の取付作業時における裏返し取付
事故の発生を未然に防止するためにとられた従来の方策
としては、第5図の如く、磁石板9の表面にN極または
S極を示す文字、符号ないし色彩を表示すること、ある
いは、磁石板9の一部を突き出しておき、裏返しに取付
けると継手3に干渉することにより判明する手段等をと
った。As a conventional measure taken to prevent the above-mentioned upside-down installation accident during the installation work of the magnet plate 9, as shown in FIG. Measures were taken such as displaying characters, codes, or colors indicating this, or by having a part of the magnet plate 9 protrude so that it would be obvious that it would interfere with the joint 3 if it was attached upside down.
しかし、前者の場合、ステータコア10を重ねると表示
が見えなくなり、表裏の正否が確認できなくなるし、後
者の場合、第6図の如く、負圧応動装置2の取付く方向
が逆の場合もあり、その場合に、磁石板9は共用できな
くなってしまい、生産上、不利となる。However, in the former case, if the stator cores 10 are overlapped, the display becomes invisible, making it impossible to confirm whether the front and back sides are correct or not.In the latter case, the negative pressure response device 2 may be installed in the opposite direction, as shown in FIG. In that case, the magnet plate 9 cannot be shared, which is disadvantageous in terms of production.
また、上記した従来技術と同様のものとして、特開昭5
1−7142峰公報に示されたものが知られている。In addition, as a similar technology to the above-mentioned prior art,
1-7142 is known.
しかしながら、このものもリラクタの回転中心と可動ベ
ースの負圧応動装置の連結点を結ぶ対称線に対して可動
ベース、ステータコアおよび磁石板の各々が対称的に固
着されていないため、リラクタの回転方向が異なる配電
器に適用する場合、磁石板をうら返して共用しようとし
ても可動ベースと磁石板の取付位置(取付ねじ穴)が合
致せず、共用化が不可能であるという問題があった。However, in this case as well, the movable base, stator core, and magnet plate are not fixed symmetrically with respect to the line of symmetry connecting the rotation center of the reluctor and the connection point of the negative pressure response device of the movable base, so the rotation direction of the reluctor When applied to power distributors with different types, there was a problem in that even if the magnet plate was turned over and the magnet plate was tried to be shared, the mounting positions (mounting screw holes) of the movable base and the magnet plate did not match, making it impossible to share the magnet plate.
本考案の目的は、可動ベースを正逆方向どちらでも回転
できるように負圧応動装置が取り付けられる配電器にお
いて、可動ベース、磁石板の誤着を防止するとともにこ
れらを共用できるようにすることにある。The purpose of this invention is to prevent the movable base and magnet plate from being attached incorrectly and to allow them to be shared in a power distribution device where a negative pressure response device is attached so that the movable base can be rotated in either forward or reverse directions. be.
本考案の特徴は、ステータコア、磁石板および可動ベー
スの各々をリラクタの回転中心と可動ベースの負圧応動
装置との連結点を結ぶ対称線に対して対称的な位置で固
着し、更に磁石板とステータコアの接触面外形をほぼ同
一形状とすると共に対称線によって二分される両領域の
外形を非対称形に形成した点にある。The feature of the present invention is that the stator core, the magnet plate, and the movable base are each fixed at a symmetrical position with respect to the line of symmetry connecting the rotation center of the reluctor and the connection point of the negative pressure response device of the movable base, and the magnet plate The outer shape of the contact surface of the stator core and the stator core are made to have substantially the same shape, and the outer shape of both regions divided into two by a line of symmetry is formed into an asymmetrical shape.
したがって、負圧応動装置の取り付は方によってリラク
タの回転方向が異なる形式の配電器であっても可動ベー
スと磁石板は共用でき、更にステータコアも磁石板とほ
ぼ同形状でかつ対称線によって二分される領域が非対称
であるため誤着も防止できるものである。Therefore, the movable base and magnet plate can be shared even if the negative pressure response device is installed in a power distribution device whose reluctor rotates in a different direction depending on the installation method.Furthermore, the stator core has almost the same shape as the magnet plate and is divided into two by the line of symmetry. Since the area where the tape is attached is asymmetrical, it is possible to prevent incorrect attachment.
第6.7.8図は、本案の実施例でステータコア20の
平面形状と磁石板21の平面形状とを同一にし、同時に
ねじ14.15の対称中心線A−Aで二分する両領域の
外形は非対称としてものである。Figure 6.7.8 shows an embodiment of the present invention in which the planar shape of the stator core 20 and the planar shape of the magnet plate 21 are made the same, and at the same time, the outer shape of both regions bisected by the center line of symmetry A-A of the screw 14.15. is also asymmetrical.
ステータコア20は、凸部202があるから裏返しには
取りつかない。Since the stator core 20 has the convex portion 202, it cannot be attached when turned inside out.
従ってステータコア20と磁石板21とを外形揃えて己
れの磁力により一体化させておきこれを可動ベース6に
載せれば、磁石板21が裏返しに取付くことはない。Therefore, if the stator core 20 and the magnet plate 21 are aligned in outer shape and integrated by their own magnetic force and then placed on the movable base 6, the magnet plate 21 will not be attached upside down.
又、組付後の確認も、外形を見ることにより実施できる
。Also, confirmation after assembly can be carried out by looking at the external shape.
万一間違って組付けられた場合、ステータコア10の切
欠部201から、磁石板21の切欠部211の反対側が
露出して見え、ステータコア20と磁石板21とは外観
色が違うので容易にチェックできる。If it is assembled incorrectly, the opposite side of the notch 211 of the magnet plate 21 will be exposed from the notch 201 of the stator core 10, and the stator core 20 and the magnet plate 21 have different external colors, so this can be easily checked. .
また、ステータコア20、磁石板21の外形は、負圧応
動装置2の継手3に干渉しない範囲であり継手ピン7を
、ねじ固着部(加締でも同じ)14.15の対称中心線
上に設定しであるから、第1図の如き、負圧応動装置2
の取付く方向が逆の場合でも、全く同一のステータコア
、マグネット、可動ベースを使うことができるから、共
用性の面から、非常に生産性の高いものである。In addition, the external shapes of the stator core 20 and magnet plate 21 are within a range that does not interfere with the joint 3 of the negative pressure response device 2, and the joint pin 7 is set on the center line of symmetry of the screw fixing part (same for caulking) 14 and 15. Therefore, the negative pressure response device 2 as shown in FIG.
Even if the stator core, magnet, and movable base are installed in the opposite direction, the same stator core, magnet, and movable base can be used, so productivity is extremely high in terms of compatibility.
また、第9〜12図は、他の実施例を示したもので、ス
テータコア22を平板で作り、凸起222を3ヶ設けた
ものである。9 to 12 show another embodiment in which the stator core 22 is made of a flat plate and three protrusions 222 are provided.
先の実施例と同じく、ステータコア22、磁石板23の
外形はねじ14.15の対称中心線に対し左右非対称と
なるような切欠部221,231を設け、ステータコア
22は表裏逆に取付けないよう押出し部223を設けで
ある。As in the previous embodiment, the stator core 22 and the magnet plate 23 are provided with notches 221 and 231 that are asymmetrical with respect to the center line of symmetry of the screws 14 and 15, and the stator core 22 is extruded so as not to be installed upside down. A section 223 is provided.
