Description

本発明は、レゾルバステータ構造に関し、特に、端子保持部のたるみピン挿入穴に肉厚部を形成し、ステータコイルの固定時に用いるワニスがたるみピン挿入穴を経て他部へ流出することを防止するための新規な改良に関する。   The present invention relates to a resolver stator structure, and in particular, forms a thick portion in a slack pin insertion hole of a terminal holding portion to prevent a varnish used when fixing a stator coil from flowing out to the other portion through the slack pin insertion hole. For new improvements.

従来、用いられていたこの種のレゾルバステータ構造としては、例えば、特許文献１及び２に開示された構成を挙げることができる。
これらの各特許文献に開示されたレゾルバのステータ構造としては、図３及び図４で示される構成であった。
すなわち、図３及び図４において符号１で示されるものは輪状ステータであり、この輪状ステータ１の両端面には一対の輪状絶縁カバー部２、３からなる輪状絶縁カバー４が設けられている。 Conventionally used resolver stator structures of this type include, for example, the configurations disclosed in Patent Documents 1 and 2.
The resolver stator structure disclosed in each of these patent documents has the configuration shown in FIGS. 3 and 4.
That is, what is denoted by reference numeral 1 in FIGS. 3 and 4 is a ring-shaped stator, and a ring-shaped insulating cover 4 including a pair of ring-shaped insulating cover portions 2 and 3 is provided on both end faces of the ring-shaped stator 1.

前記輪状ステータ１の内方へ突出して形成された各磁極５の外周には、その両面に前記輪状絶縁カバー４を介してステータコイル６が巻回して設けられており、このステータコイル６の端線６ａは、前記輪状絶縁カバー４の一部から一体に半径方向に沿って突出して形成された端子保持部７に設けられた端子ピン８にからげて接続されている。   A stator coil 6 is wound around the outer periphery of each magnetic pole 5 formed so as to protrude inward of the annular stator 1 via the annular insulating cover 4. The wire 6a is connected to a terminal pin 8 provided on a terminal holding portion 7 formed so as to protrude integrally from a part of the annular insulating cover 4 along the radial direction.

前記端子保持部７における前記端子ピン８の内側位置、すなわち、前記端子ピン８と磁極５との間の位置には、複数のたるみピン挿入穴９が形成されている。
前記たるみピン挿入穴９には、前記各端線６ａのたるみを取るためのたるみピン１０を挿入することができるように構成されており、この端線６ａをこのたるみピン１０によって曲折させることにより、たるみを付けるように構成されている。すなわち、たるみピン１０を外すとステータコイル６の端線６ａにたるみが付くように構成されている。 A plurality of slack pin insertion holes 9 are formed at an inner position of the terminal pin 8 in the terminal holding portion 7, that is, at a position between the terminal pin 8 and the magnetic pole 5.
The slack pin insertion hole 9 is configured so that a slack pin 10 for removing slack of each end line 6a can be inserted. By bending the end line 6a with the slack pin 10, the slack pin 10 is bent. It is configured to sag. That is, when the slack pin 10 is removed, the end line 6a of the stator coil 6 is slackened.

従来のレゾルバのステータ構造は、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、各磁極に巻回したステータコイルの端線を端子ピンにからげた後に、磁極等のステータコイルのコイル固定をするために、輪状ステータを水平状態に配置した後、輪状絶縁カバー部の壁の内側に溶融状のワニスを供給すると、このワニスの固化によってステータコイルが固定されるが、この時に、たるみピン挿入穴の穴口は端子保持部の面と同一平面であるため、ワニスがこのたるみピン挿入穴から他の部分に流出してしまい、ワニスが無駄となり、多量のワニスを必要とすることになっていた。
尚、前述の作業の後に、各たるみピン挿入穴にたるみピンを挿入して端線を曲折させることにより、端線を張らせ、巻線後にたるみピンを外すことにより、ステータコイルの端線にたるみを付けていた。 Since the conventional resolver stator structure is configured as described above, the following problems exist.
That is, after winding the end line of the stator coil wound around each magnetic pole to the terminal pin, in order to fix the stator coil such as the magnetic pole, the annular stator is placed in a horizontal state, and then the wall of the annular insulating cover part When the molten varnish is supplied inside, the stator coil is fixed by the solidification of the varnish. At this time, the hole of the slack pin insertion hole is flush with the surface of the terminal holding portion. It flowed out from the pin insertion hole to other parts, the varnish was wasted, and a large amount of varnish was required.
After the above work, insert the slack pin into each slack pin insertion hole and bend the end line to stretch the end line, and then remove the slack pin after winding to the end line of the stator coil. It was slack.

本発明によるレゾルバステータ構造は、輪状ステータの各磁極に輪状絶縁カバーを介してステータコイルを巻付け、前記輪状絶縁カバーの一端に設けられた端子保持部の各端子ピンに前記ステータコイルを接続するようにしたレゾルバステータ構造において、前記端子保持部における前記端子ピンと磁極との間に設けられたたるみピン挿入穴と、前記たるみピン挿入穴に設けられた肉厚部とを備え、前記肉厚部は前記端子保持部から前記輪状ステータの軸方向に沿って突出している構成であり、また、１個の前記肉厚部には複数の前記たるみピン挿入穴が形成されている構成である。   In the resolver stator structure according to the present invention, a stator coil is wound around each magnetic pole of a ring-shaped stator via a ring-shaped insulating cover, and the stator coil is connected to each terminal pin of a terminal holding portion provided at one end of the ring-shaped insulating cover. In the resolver stator structure as described above, the thick portion includes a slack pin insertion hole provided between the terminal pin and the magnetic pole in the terminal holding portion, and a thick portion provided in the slack pin insertion hole. Is a configuration projecting from the terminal holding portion along the axial direction of the ring-shaped stator, and a plurality of slack pin insertion holes are formed in one thick portion.

本発明によるレゾルバステータ構造は、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、端子保持部に形成され軸方向にその部分だけ盛り上がった状態の肉厚部が形成され、この肉厚部にたるみピン挿入穴が形成されているため、ワニスによるコイル固定作業においてもワニスがこの肉厚部をほとんど乗り越えることができず、その結果、たるみピン挿入穴内にほとんど入り込まずワニスの量を従来よりも少なくすることができる。
また、たるみピン挿入穴内にワニスが入り込む量が少なくなるため、外観不良を無くすことができる。 Since the resolver stator structure according to the present invention is configured as described above, the following effects can be obtained.
That is, a thick part formed in the terminal holding part and raised only in the axial direction is formed, and a slack pin insertion hole is formed in this thick part. This thick portion cannot be almost overcome, and as a result, the amount of varnish can be reduced as compared with the conventional case, while hardly entering the slack pin insertion hole.
In addition, since the amount of varnish entering the slack pin insertion hole is reduced, appearance defects can be eliminated.

本発明は、端子保持部に形成した肉厚部にたるみピン挿入穴を形成することにより、ワニスによるコイル固定作業時に、ワニスがたるみピン挿入穴に入ることを防止し、ワニスの無駄や品質劣化を防止することを目的とする。   By forming a slack pin insertion hole in the thick part formed in the terminal holding part, the present invention prevents the varnish from entering the slack pin insertion hole during the coil fixing work by the varnish, and waste of the varnish and quality deterioration The purpose is to prevent.

以下、図面と共に本発明によるレゾルバステータ構造の好適な実施の形態について説明する。
図１及び図２において符号１で示されるものは輪状ステータであり、この輪状ステータ１の両端面には一対の輪状絶縁カバー部２、３からなる輪状絶縁カバー４が設けられている。
尚、この輪状絶縁カバー４は、図２のように一対の輪状絶縁カバー２、３を別体として形成した場合と、一体成形の場合等の何れの場合も可である。 Hereinafter, preferred embodiments of a resolver stator structure according to the present invention will be described with reference to the drawings.
1 and 2 is a ring-shaped stator, and a ring-shaped insulating cover 4 including a pair of ring-shaped insulating cover portions 2 and 3 is provided on both end surfaces of the ring-shaped stator 1.
The ring-shaped insulating cover 4 can be used either in the case where the pair of ring-shaped insulating covers 2 and 3 are formed separately as shown in FIG.

前記輪状ステータ１の内方へ突出して形成された各磁極５の外周には、その両面に前記輪状絶縁カバー４を介してステータコイル６が巻回して設けられており、このステータコイル６の端線６ａは、前記輪状絶縁カバー４の一部から一体に半径方向に沿って突出して形成された端子保持部７に設けられた端子ピン８にからげて接続されている。   A stator coil 6 is wound around the outer periphery of each magnetic pole 5 formed so as to protrude inward of the annular stator 1 via the annular insulating cover 4. The wire 6a is connected to a terminal pin 8 provided on a terminal holding portion 7 formed so as to protrude integrally from a part of the annular insulating cover 4 along the radial direction.

前記端子保持部７における前記端子ピン８の内側位置、すなわち、前記端子ピン８と磁極５との間の位置には、複数のたるみピン挿入穴９が形成されている。
前記たるみピン挿入穴９には、前記各端線６ａのたるみを取るためのたるみピン１０を挿入することができるように構成されており、この端線６ａをこのたるみピン１０によって曲折させることにより、たるみピンを除去することによりステータコイルの端線にたるみが付けられるように構成されている。 A plurality of slack pin insertion holes 9 are formed at an inner position of the terminal pin 8 in the terminal holding portion 7, that is, at a position between the terminal pin 8 and the magnetic pole 5.
The slack pin insertion hole 9 is configured so that a slack pin 10 for removing slack of each end line 6 a can be inserted. By bending the end line 6 a with the slack pin 10, The slack pins are removed so that the end lines of the stator coil can be slackened.

前記端子保持部７における前記端子ピン８と磁極５との間には、アイランド状に浮き上がって形成され、輪状ステータ１の軸方向Ａに沿って突出する肉厚部２０が設けられており、この１個の肉厚部２０には複数の前記たるみピン挿入穴９が形成されている。   A thick portion 20 is provided between the terminal pin 8 and the magnetic pole 5 in the terminal holding portion 7 so as to float in an island shape and project along the axial direction A of the annular stator 1. A plurality of the slack pin insertion holes 9 are formed in one thick portion 20.

前記肉厚部２０の各たるみピン挿入穴９の入口は、従来の図３で示した構成よりもこの肉厚部２０分だけ端子保持部７の面よりも高く形成され、従来のように、ステータコイル６の固定のために、ワニスを輪状絶縁カバー部２、３の輪状壁２ａ、３ａの内側に流し込んで供給した場合でも、この肉厚部２０の高さによってワニスはたるみピン挿入穴９内にほとんど流れ込むことはなく、従来のような、ワニスの無駄が防止できる。   The entrance of each slack pin insertion hole 9 of the thick portion 20 is formed higher than the surface of the terminal holding portion 7 by the thick portion 20 than the conventional configuration shown in FIG. Even when the varnish is poured into the annular walls 2 a and 3 a of the annular insulating cover portions 2 and 3 and supplied for fixing the stator coil 6, the varnish becomes a slack pin insertion hole 9 due to the height of the thick portion 20. The varnish can be prevented from being wasted as before.

本発明は、レゾルバに限ることなく、モータ、アクチュエータ等の端子構造に適用可である。   The present invention is not limited to a resolver, but can be applied to terminal structures such as motors and actuators.
