Description

本発明は、レゾルバステータ構造に関し、特に、ハーネス接続端子の取付位置を輪状ステータの外周の内側とし、機器へのレゾルバの取付けを容易化するための新規な改良に関する。   The present invention relates to a resolver stator structure, and more particularly, to a novel improvement for facilitating the attachment of a resolver to a device by setting the attachment position of a harness connection terminal to the inside of the outer periphery of a ring-shaped stator.

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、２、３に開示されている構成が採用されており、実際に製品化された構成としては、図３から図６で示される構成を挙げることができる。   As this type of resolver stator structure that has been used in the past, for example, the configurations disclosed in Patent Documents 1, 2, and 3 are adopted. The structure shown by 6 can be mentioned.

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の内面には、内方へ向けて突出する複数の磁極２が所定間隔で形成されている。
前記輪状ステータ１の第１、第２面１ａ、１ｂには、第１、第２輪状絶縁カバー３、４が設けられ、前記各磁極２には前記各輪状絶縁カバー３、４を介してステータ巻線５が設けられている。 3 and 4 is a ring-shaped stator, and a plurality of magnetic poles 2 projecting inward are formed at predetermined intervals on the inner surface of the ring-shaped stator 1.
First and second ring-shaped insulating covers 3 and 4 are provided on the first and second surfaces 1a and 1b of the ring-shaped stator 1, and each magnetic pole 2 is connected to the stator via the ring-shaped insulating covers 3 and 4 respectively. A winding 5 is provided.

前記各輪状絶縁カバー３、４は、前記輪状ステータ１の外周１ｃで一体でかつ端子保持部６を形成し、この端子保持部６にはＬ字型のハーネス接続端子７が一体成形されている。
このハーネス接続端子７の一端７ａにはステータ巻線５の端線が巻付けられ、その他端７ｂは輪状ステータ１の径方向に沿って延設されている。 Each of the ring-shaped insulating covers 3 and 4 is integrally formed with the outer periphery 1c of the ring-shaped stator 1 and forms a terminal holding portion 6. The terminal holding portion 6 is integrally formed with an L-shaped harness connection terminal 7. .
An end line of the stator winding 5 is wound around one end 7 a of the harness connection terminal 7, and the other end 7 b extends along the radial direction of the annular stator 1.

次に、図５及び図６に示される構成は、図３及び図５の他の構成を示しており、前記端子保持部６の取付位置が輪状ステータ１の第２面１ｂ側へ変更になっているだけで、他の構成は図３及び図５の構成と同一であるため、同一部分には同一符号を付し、その説明は省略する。   Next, the configuration shown in FIGS. 5 and 6 shows another configuration of FIGS. 3 and 5, and the mounting position of the terminal holding portion 6 is changed to the second surface 1 b side of the annular stator 1. However, since the other structure is the same as the structure of FIG.3 and FIG.5, the same code | symbol is attached | subjected to the same part and the description is abbreviate | omitted.

特開１１−９８７４８号公報JP 11-98748 A 特開１１−９８７４７号公報JP 11-98747 A 米国特許第６０２８３８３号明細書US Pat. No. 6,028,383

従来のレゾルバステータ構造は、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、端子保持部及びハーネス接続端子が輪状ステータの外周すなわち外径から外側へ突出して位置していたため、機器への取付けスペースにおいて、端子を逃がすための逃げが必要であり、取付け側におけるスペース確保が必要で、機器の小型化への障害となっていた。
また、輪状ステータの外周をインローとして用いることができず、端子方向へステータが偏って取付けられることになり、この取付偏心によって角度検出精度が低下することがあった。
また、特許文献３の米国特許に開示された構成は、端子保持部が輪状ステータの外周の内側に位置しているが、接続リード線は、輪状ステータの径方向に沿って引出されるように接続されるため、前述と同様の課題が存在していた。 Since the conventional resolver stator structure is configured as described above, the following problems exist.
That is, since the terminal holding part and the harness connection terminal are located so as to protrude outward from the outer periphery of the ring-shaped stator, that is, from the outer diameter, it is necessary to escape in order to escape the terminal in the mounting space to the equipment, and secure the space on the mounting side Is necessary, and has become an obstacle to downsizing of equipment.
In addition, the outer periphery of the ring-shaped stator cannot be used as an inlay, and the stator is attached in a biased direction in the terminal direction, and the angle detection accuracy may be lowered due to this attachment eccentricity.
Further, in the configuration disclosed in the US patent of Patent Document 3, the terminal holding portion is located inside the outer periphery of the annular stator, but the connection lead wire is drawn out along the radial direction of the annular stator. Since they are connected, the same problem as described above exists.

本発明によるレゾルバステータ構造は、所定間隔で内方へ向けて突出する複数の磁極を有する輪状ステータと、前記輪状ステータの両面に設けられた第１、第２輪状絶縁カバーを介して前記各磁極に巻回されたステータ巻線と、前記第１、第２輪状絶縁カバーの何れかの周縁に設けられＬ字型のハーネス接続端子を有する端子保持部とを有し、前記ハーネス接続端子は前記輪状ステータの外周の内側に位置し、前記ハーネス接続端子の一端には前記ステータ巻線が巻付けられ、前記ハーネス接続端子の他端は前記輪状ステータの軸方向に沿って延設されている構成であり、また、前記ハーネス接続端子の前記一端は、前記磁極と重合している構成であり、また、前記輪状ステータの外周は、インローとして用いられる構成である。   The resolver stator structure according to the present invention includes a ring-shaped stator having a plurality of magnetic poles protruding inward at predetermined intervals, and the magnetic poles via first and second ring-shaped insulating covers provided on both surfaces of the ring-shaped stator. And a terminal holding part having an L-shaped harness connection terminal provided on the periphery of any of the first and second annular insulating covers, and the harness connection terminal Positioned inside the outer periphery of the annular stator, the stator winding is wound around one end of the harness connection terminal, and the other end of the harness connection terminal extends along the axial direction of the annular stator Further, the one end of the harness connection terminal is overlapped with the magnetic pole, and the outer periphery of the ring-shaped stator is used as an inlay.

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、ハーネス接続端子及び端子保持部が輪状ステータの外周の内側に位置しているため、輪状ステータの外周の全周をインローとして機器へ取付けができ、従来発生していた不具合を解消し、検出精度の低下を防ぎ、かつ、取付部スペースに逃げを設ける必要がなく、取付けと精度向上の両方を達成することができる。 Since the resolver stator structure according to the present invention is configured as described above, the following effects can be obtained.
In other words, since the harness connection terminal and the terminal holding part are located inside the outer periphery of the ring-shaped stator, the entire outer periphery of the ring-shaped stator can be attached to the equipment as a spigot, eliminating the problems that have occurred in the past and detecting It is possible to prevent both the accuracy and accuracy from being improved, and it is not necessary to provide a clearance in the mounting space.

本発明は、ハーネス接続端子及び端子保持部を輪状ステータの外周の内側に位置させ、輪状ステータの外周をインローとして機器への取付けを可能とし、検出精度の向上を得ることを目的とする。   It is an object of the present invention to position a harness connection terminal and a terminal holding portion inside an outer periphery of a ring-shaped stator so that the outer periphery of the ring-shaped stator can be attached to a device and can be improved in detection accuracy.

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。尚、従来例と同一又は同等部分については同一符号を用いて説明する。
図１において符号１で示されるものは輪状ステータであり、この輪状ステータ１の内面には、内方へ向けて突出する複数の磁極２が所定間隔で形成されている。 Hereinafter, preferred embodiments of a resolver stator structure according to the present invention will be described with reference to the drawings. Note that the same or equivalent parts as in the conventional example will be described using the same reference numerals.
1 is a ring-shaped stator, and a plurality of magnetic poles 2 projecting inward are formed at predetermined intervals on the inner surface of the ring-shaped stator 1.

前記輪状ステータ１の第１、第２面１ａ、１ｂには、第１、第２輪状絶縁カバー３、４が設けられ、前記各磁極２には前記各輪状絶縁カバー３、４を介してステータ巻線５が設けられている。   First and second ring-shaped insulating covers 3 and 4 are provided on the first and second surfaces 1a and 1b of the ring-shaped stator 1, and each magnetic pole 2 is connected to the stator via the ring-shaped insulating covers 3 and 4 respectively. Winding 5 is provided.

前記各輪状絶縁カバー３、４の中の何れか一方、ここでは、第２輪状絶縁カバー４（第１輪状絶縁カバー３でも可）の外端位置に、これと一体又は別体にて形成された横長形状の端子保持部６が設けられ、この端子保持部６は、図２で示されるように、輪状ステータ１の外周１ｃの内側に位置するように配設されている。   Either one of the ring-shaped insulating covers 3 and 4, here, the second ring-shaped insulating cover 4 (or the first ring-shaped insulating cover 3 is acceptable) is formed integrally with or separately from the outer end position. A horizontally long terminal holding part 6 is provided, and this terminal holding part 6 is arranged so as to be located inside the outer periphery 1c of the annular stator 1 as shown in FIG.

前記端子保持部６には、Ｌ字型をなすハーネス接続端子７が一体成形されており、各ハーネス接続端子７は何れも前記輪状ステータ１の外周（すなわち外径）の内側に位置し、その一端７ａは前記磁極２及びステータ巻線５と重合すると共にステータ巻線５の端線が巻付けられ、その他端７ｂは輪状ステータ１の軸方向に沿って延設されている。   The terminal holding part 6 is integrally formed with an L-shaped harness connection terminal 7, and each harness connection terminal 7 is located inside the outer periphery (ie, outer diameter) of the annular stator 1, One end 7 a overlaps with the magnetic pole 2 and the stator winding 5, and an end line of the stator winding 5 is wound thereon, and the other end 7 b extends along the axial direction of the annular stator 1.

前記輪状ステータ１の外周１ｃには、従来のように、端子保持部６等が何ら位置していないため、この輪状ステータ１を用いたレゾルバステータを図示しない機器の取付部に取付ける場合、この輪状ステータ１の外周１ｃをインローとして取付けることができ、従来のように、偏心を伴うことなく装着でき、検出精度も向上させることができる。   Since the outer periphery 1c of the annular stator 1 is not provided with any terminal holding portion 6 or the like as in the prior art, when the resolver stator using the annular stator 1 is attached to an attachment portion of a device (not shown), this annular shape The outer periphery 1c of the stator 1 can be attached as an inlay, and can be mounted without being eccentric as in the conventional case, and the detection accuracy can be improved.

本発明は、レゾルバのみに限ることなく、例えば、シンクロ、エンコーダ、モータ等にも適用可能である。   The present invention is not limited to a resolver, but can be applied to, for example, a synchro, an encoder, a motor, and the like.
