Description

本発明は、レゾルバ端子ピン構造に関し、特に、アウターロータ型の構造における輪状ステータの端子ピンにステータ巻線をからげた後に、この端子ピンを軸方向移動させることにより、ステータ巻線のからげを容易化すると共に、たるみを形成させることができるようにするための新規な改良に関する。   The present invention relates to a resolver terminal pin structure, and in particular, after a stator winding is tangled to a terminal pin of a ring-shaped stator in an outer rotor type structure, the terminal pin is moved in the axial direction, thereby tangling the stator winding. It relates to a novel improvement for facilitating and allowing slack to be formed.

従来、用いられていたこの種のレゾルバとしては、例えば、特許文献1及び特許文献2に開示された構成を挙げることができる。
すなわち、図示していないが、輪状ステータの内側にロータが設けられ、この輪状ステータの周面の一部に複数の端子ピンを有する端子ピン保持部がステータ巻線のステータカバーと一体に形成されている。
従って、輪状ステータに巻付け後のステータ巻線は、この端子ピン保持部の端子ピンにからげていた。

That is, although not shown, a rotor is provided inside the annular stator, and a terminal pin holding portion having a plurality of terminal pins on a part of the circumferential surface of the annular stator is formed integrally with the stator cover of the stator winding. ing.
Therefore, the stator winding after being wound around the ring-shaped stator is entangled with the terminal pins of the terminal pin holding portion.

従来のレゾルバは、以上のように構成されていたため、次のような課題が存在していた。
すなわち、インナーロータ型の場合は、輪状ステータの内側にロータが配設されているため、輪状ステータの外周に設けられている端子にステータ巻線をからげることは極めて容易であるが、アウターロータ型の場合は、輪状ステータの外側に輪状ロータが配設され、輪状ステータの中央位置に設けられた限られた長さの端子ピンにステータ巻線をからげ、かつ、たるみを形成することは極めて困難であった。
Since the conventional resolver is configured as described above, the following problems exist.
That is, in the case of the inner rotor type, since the rotor is disposed inside the annular stator, it is extremely easy to tie the stator winding to the terminal provided on the outer periphery of the annular stator. In the case of the rotor type, a ring-shaped rotor is disposed outside the ring-shaped stator, the stator winding is tangled to a terminal pin of a limited length provided at the center position of the ring-shaped stator, and slack is formed. Was extremely difficult.

本発明によるレゾルバ端子ピン構造は、ステータ巻線を有し外周面に所定間隔で磁極を有する輪状ステータと、前記輪状ステータを軸方向に貫通して形成された複数の貫通孔と、前記各貫通孔に挿入された端子ピンと、前記輪状ステータの外周面の外側に回転可能に配設された輪状ロータと、前記輪状ロータの内周面に形成され非真円状をなす非真円面部とを備え、前記端子ピンは前記ステータ巻線をからげ後に軸方向に移動させた構成であり、また、前記輪状ステータに第1樹脂モールドを形成した後に、前記端子ピンが挿入されている構成であり、また、前記端子ピンを軸方向に移動させた後に、前記第1樹脂モールドの表面に第2樹脂モールドを形成し、前記第2樹脂モールドによって前記ステータ巻線及び前記からげによるからげ部が樹脂で覆われている構成であり、また、前記第1樹脂モールドは前記輪状ステータとステータ巻線間の絶縁部材をなし、前記第2樹脂モールドは前記ステータ巻線及び端子ピンを覆う絶縁カバーをなす構成である。   The resolver terminal pin structure according to the present invention includes a ring-shaped stator having stator windings and magnetic poles at predetermined intervals on an outer peripheral surface, a plurality of through holes formed through the ring-shaped stator in the axial direction, and each of the through holes. A terminal pin inserted into the hole, a ring-shaped rotor rotatably disposed on the outer peripheral surface of the ring-shaped stator, and a non-round surface portion formed on the inner peripheral surface of the ring-shaped rotor and having a non-circular shape. And the terminal pin is a configuration in which the stator winding is tangled and moved in the axial direction, and the terminal pin is inserted after the first resin mold is formed on the annular stator. In addition, after the terminal pin is moved in the axial direction, a second resin mold is formed on the surface of the first resin mold, and the stator winding and the curled portion by the curl are formed by the second resin mold. The first resin mold includes an insulating member between the annular stator and the stator winding, and the second resin mold includes an insulating cover that covers the stator winding and the terminal pin. It is a structure to make.

本発明によるレゾルバ端子ピン構造は以上のように構成されているため、次のような効果を得ることができる。
すなわち、輪状ステータの貫通孔に挿入された端子ピンを、この貫通孔から突出させた状態でステータ巻線をからげ、その後、この端子ピンを軸方向に押し込むことによりステータ巻線にたるみが形成され、からげとたるみを簡単に形成することができる。
Since the resolver terminal pin structure according to the present invention is configured as described above, the following effects can be obtained.
That is, the terminal pin inserted into the through hole of the ring-shaped stator is entangled with the stator winding in a state of protruding from the through hole, and then the terminal pin is pushed in the axial direction to form a slack in the stator winding. Therefore, it is possible to easily form tangles and sagging.

本発明は、アウターロータ型のレゾルバにおける輪状ステータの端子ピンを突出させた状態でからげた後に、引き込めることにより、からげとたるみを簡単に形成することを目的とする。     SUMMARY OF THE INVENTION An object of the present invention is to easily form sag and slack by pulling a terminal pin of a ring-shaped stator in an outer rotor type resolver in a protruding state and then retracting it.

以下、図面と共に本発明によるレゾルバ端子ピン構造の好適な実施の形態について説明する。
図1において符号1で示されるものは輪状ロータであり、この輪状ロータ1の内周面は4個の凹部を有すると共に真円を構成していない非真円面部2が形成されている。
Hereinafter, preferred embodiments of a resolver terminal pin structure according to the present invention will be described with reference to the drawings.
1 is a ring-shaped rotor, and an inner peripheral surface of the ring-shaped rotor 1 has four concave portions and a non-round surface portion 2 that does not constitute a perfect circle.

前記輪状ロータ1の内側には、輪状をなすと共に複数の磁極3を所定間隔でその外周に突出させて有する輪状ステータ4が固定配置されていることにより、アウターロータ型のレゾルバを構成している。   An annular rotor 4 having an annular shape and a plurality of magnetic poles 3 protruding from the outer periphery at predetermined intervals is fixedly arranged inside the annular rotor 1 to constitute an outer rotor type resolver. .

前記輪状ステータ4には、その中心孔5の周縁に位置するように、複数の貫通孔6が形成されると共に、この輪状ステータ4の各磁極3間に形成されたスロット(図示せず)に巻回されたステータ巻線7は、前記各貫通孔6に挿入された端子ピン8にからげ(巻付け)られ、からげ部30が形成されている。   A plurality of through holes 6 are formed in the annular stator 4 so as to be positioned at the periphery of the center hole 5, and slots (not shown) formed between the magnetic poles 3 of the annular stator 4 are formed. The wound stator winding 7 is wound (wound) around the terminal pins 8 inserted into the respective through holes 6 to form a bent portion 30.

次に、前述の構造のアウターロータ型のレゾルバを構成する場合、前記輪状ステータ4の両端面に絶縁部材としての第1樹脂モールド10を形成する。
前記第1樹脂モールド10は、モールド成形時に前記貫通孔6内にも樹脂が入り込んで埋った状態となり、この状態で長手形状の前記端子ピン8をこの貫通孔6内に挿入することにより、この端子ピン8は貫通孔6に対して適度の摩擦を有する状態で軸方向に移動可能に保持される。
Next, when the outer rotor type resolver having the above-described structure is configured, first resin molds 10 as insulating members are formed on both end surfaces of the annular stator 4.
The first resin mold 10 is in a state where the resin also enters and fills the through hole 6 at the time of molding, and by inserting the long terminal pin 8 into the through hole 6 in this state, The terminal pin 8 is held so as to be movable in the axial direction while having an appropriate friction with respect to the through hole 6.

次に、前述の状態で、輪状ステータ4の各スロットに対し、前記第1樹脂モールド10を絶縁部材として自動巻線機(図示せず)によりステータ巻線7の巻き付けを行う。
このステータ巻線7の巻付け時は、端子ピン8が図2の(A)の状態のように左側へ移動して突出されているため、スロットに巻き付け後のステータ巻線7はこの自動巻線機によって端子ピン8に容易にからげられる。
Next, in the above-described state, the stator winding 7 is wound around each slot of the annular stator 4 by the automatic winding machine (not shown) using the first resin mold 10 as an insulating member.
When the stator winding 7 is wound, since the terminal pin 8 is moved to the left as shown in FIG. 2A and protrudes, the stator winding 7 wound around the slot is automatically wound. It is easily tangled to the terminal pin 8 by the wire machine.

前述のように、端子ピン8の一端側へのステータ巻線7の巻き付けが完了すると、この端子ピン8を矢印Aの方向に押し込むことによってたるみ18が形成され、図2の(B)の状態となる。   As described above, when the winding of the stator winding 7 around one end of the terminal pin 8 is completed, a slack 18 is formed by pushing the terminal pin 8 in the direction of arrow A, and the state shown in FIG. It becomes.

この図2の(B)の状態で、絶縁カバーとしての第2樹脂モールド20を輪状ステータ4の外面に形成することにより、前記ステータ巻線7及び端子ピン8の一端8aはこの第2樹脂モールド20内に埋設され、端子ピン8の他端8bがこの第2樹脂モールド20の表面20aから外方へ突出している。
この端子ピン8の他端8bは、図示しない外部のコネクタ等に接続されて、レゾルバ出力信号が出力される。
In the state of FIG. 2B, a second resin mold 20 as an insulating cover is formed on the outer surface of the annular stator 4 so that the stator winding 7 and one end 8a of the terminal pin 8 are connected to the second resin mold. The other end 8 b of the terminal pin 8 protrudes outward from the surface 20 a of the second resin mold 20.
The other end 8b of the terminal pin 8 is connected to an external connector or the like (not shown), and a resolver output signal is output.

本発明は、レゾルバだけではなく、アウターロータ型のモータにも適用性がある。   The present invention is applicable not only to a resolver but also to an outer rotor type motor.
