Description
本発明は、レゾルバステータ構造に関し、特に、各端子ピンの周囲に壁によって囲まれた複数のワニス溜り用凹部を形成し、各巻線の端線を各端子ピンにからげてワニス処理した場合におけるワニスからの浮き線の発生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, when a plurality of varnish storage recesses surrounded by walls are formed around each terminal pin, and the end line of each winding is entangled with each terminal pin and varnished. The present invention relates to a novel improvement for preventing the occurrence of floating lines from a varnish.
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、後述の特許文献１及び２に開示された構成を図３及び図４に示すことができる。
すなわち、図３及び図４において符号１で示されるものは全体形状が輪状をなす輪状ステータであり、この輪状ステータ１の内面１ａには、所定角度間隔で内方に突出して形成される複数の磁極２が配設されている。
As this type of resolver stator structure conventionally used, for example, the configurations disclosed in Patent Documents 1 and 2 described later can be 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 having a ring shape as a whole, and a plurality of inner surfaces 1a of the ring-shaped stator 1 are formed to protrude inward at predetermined angular intervals. A magnetic pole 2 is provided.
前記輪状ステータ１の両面には、前記各磁極２の外周を覆うように輪状絶縁キャップ３が形成され、この輪状絶縁キャップ３は、図示のように、輪状ステータ１に対してインサート成形による一体成形の場合、又は、図示しないが予め一対の第１、第２輪状絶縁キャップとして別部品で成形されたものを輪状ステータ１の両面から取付ける構成も採用される。 A ring-shaped insulating cap 3 is formed on both surfaces of the ring-shaped stator 1 so as to cover the outer periphery of each magnetic pole 2, and the ring-shaped insulating cap 3 is integrally formed by insert molding with respect to the ring-shaped stator 1 as shown in the figure. In this case, although not shown, a configuration in which a pair of first and second ring-shaped insulating caps previously molded as separate parts is attached from both surfaces of the ring-shaped stator 1 is also employed.
前記輪状絶縁キャップ３の一端側である一部３ａには、この輪状ステータ１の半径方向に突出するように端子ピン保持部４が一体成形により形成されている。
前記端子ピン保持部４の側部周囲には、この側部周囲を囲うように端子ピン保持部壁５が形成され、この端子ピン保持部４の一面４ａには、この端子ピン保持部４を囲むことによって形成される凹部からなるワニス溜り用凹部６が形成されている。
A terminal pin holding portion 4 is integrally formed on a part 3 a which is one end side of the annular insulating cap 3 so as to protrude in the radial direction of the annular stator 1.
A terminal pin holding portion wall 5 is formed around the side portion of the terminal pin holding portion 4 so as to surround the side portion, and the terminal pin holding portion 4 is provided on one
前記ワニス溜り用凹部６内には、複数の端子ピン７が互いに離間して直列状に植立して設けられており、この一面４ａには前記ワニス溜り用凹部６に隣接する状態で複数のガイドピン９が設けられている。
In the varnish reservoir recess 6, a plurality of terminal pins 7 are provided so as to be spaced apart from each other and planted in series. A plurality of terminal pins 7 are adjacent to the varnish reservoir recess 6 on the one
前記各磁極２には、前記輪状絶縁キャップ３によって絶縁された状態で周知のステータ巻線からなる巻線８が巻回して設けられており、各巻線８の端線８ａは、前記各ガイドピン９を介して前記各端子ピン７にからげて接続され、周知の半田又はフュージングによって固定されている。 Each magnetic pole 2 is provided with a winding 8 made of a well-known stator winding in a state insulated by the ring-shaped insulating cap 3, and an end line 8a of each winding 8 is connected to each guide pin. 9 is connected to each terminal pin 7 via 9 and fixed by known soldering or fusing.
前記各端子ピン７にからげて接続された前記端線８ａは、その直線又は曲線部分が振動等によって振れることのないように、前記ワニス溜り用凹部６内に供給されたワニス１０によって、固められるように構成されている。 The end lines 8a connected to the terminal pins 7 are solidified by the varnish 10 supplied into the varnish storage recess 6 so that the straight line or the curved portion is not shaken by vibration or the like. It is configured to be.
従って、前述の構成によって形成された輪状ステータ構造２０の各磁極２の内側には、図示しないバリアブルリラクタンス型のロータが回転自在に設けられ、回転角度検出ができる。 Therefore, a variable reluctance type rotor (not shown) is rotatably provided inside each magnetic pole 2 of the annular stator structure 20 formed by the above-described configuration, and the rotation angle can be detected.
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るため、次のような課題が存在していた。
すなわち、端子ピン保持部に形成されたワニス溜り用凹部が各端子ピンに対して共通の１個形状であるため、巻線の完了後にワニス溜り用凹部内にワニスを供給して巻線の端線をワニスによって含浸固定する時に、ワニスの量を多くしないとワニス溜り用凹部内全体にワニスが行きわたらないことになり、多くのワニスを必要とすると共に、輪状ステータが水平状態からわずかでも傾いた場合、ワニスも傾斜して固まることになり、一方側の端子ピンに対する端線がワニスから浮き、固定することができず、他方側ではワニスがワニス溜り用凹部から溢れて垂れることになっていた。
前述のように、一方側の端子ピンの端線がワニスから浮いて浮き線の発生となった場合には、後加工によってワニスを追加して浮き線を覆わなければならなかった。
Since the conventional resolver stator structure is configured as described above, the following problems exist.
In other words, since the varnish reservoir recess formed in the terminal pin holding portion has one common shape for each terminal pin, the varnish is supplied into the varnish reservoir recess after the winding is completed. When the wire is impregnated and fixed with varnish, if the amount of varnish is not increased, the varnish will not reach the entire recess for storing the varnish, which requires a lot of varnish, and the annular stator is slightly inclined from the horizontal state. In this case, the varnish also tilts and hardens, the end line to the terminal pin on one side floats from the varnish and cannot be fixed, and on the other side the varnish overflows from the varnish storage recess and hangs down. It was.
As described above, when the end line of the terminal pin on one side floats from the varnish to generate a floating line, the varnish must be added by post-processing to cover the floating line.
本発明によるレゾルバステータ構造は、所定角度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前記各磁極を覆うための一体もしくは一対の輪状絶縁キャップと、前記輪状絶縁キャップの一部から外方へ向けて一体に突出する端子ピン保持部と、前記端子ピン保持部に設けられ互いに間隔をおいて配設された複数の端子ピンと、前記端子ピン保持部に形成され前記端子ピン保持部の側部周囲を囲うように位置する端子ピン保持部壁と、前記端子ピン保持部の一面に形成され前記各端子ピン間に位置する複数の端子ピン間壁と、前記各磁極に巻回されその各端線が前記各端子ピンにからげて接続された巻線と、前記各端子ピン間壁と前記端子ピン保持部壁によって前記各端子ピンの周囲に形成された複数のワニス溜り用凹部と、前記各ワニス溜り用凹部内に供給されたワニスと、を備え、前記巻線の端線は、前記ワニスにより保持されている構成であり、また、前記端子ピン保持部壁及び端子ピン間壁は、前記端子ピン保持部に一体成形されている構成である。 A resolver stator structure according to the present invention includes a ring-shaped stator having a plurality of magnetic poles projecting inward at predetermined angular intervals, and a single or pair of ring-shaped insulating caps provided on both surfaces of the ring-shaped stator to cover the magnetic poles. A terminal pin holding part integrally protruding outward from a part of the ring-shaped insulating cap, a plurality of terminal pins provided in the terminal pin holding part and spaced from each other, and the terminal pin A terminal pin holding portion wall that is formed on the holding portion and is positioned so as to surround a side portion of the terminal pin holding portion, and a plurality of terminal pins that are formed on one surface of the terminal pin holding portion and located between the terminal pins. Surrounding each terminal pin by a wall, a winding wound around each of the magnetic poles, and each end line of the winding being connected to each terminal pin, the wall between the terminal pins, and the terminal pin holding portion wall In A plurality of varnish reservoir recesses formed, and a varnish supplied into each of the varnish reservoir recesses, wherein the winding end line is held by the varnish, and The terminal pin holding part wall and the terminal pin inter-part wall are formed integrally with the terminal pin holding part.
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、端子ピン保持部に設けられたワニス溜り用凹部内に、各端子ピン間を仕切る状態で端子ピン間壁が形成されているため、ワニス溜り用凹部が各端子ピン間壁によって細分化された状態となり、ワニス供給後に輪状ステータが傾斜した状態で乾燥工程を経た場合でも、ワニスは各端子ピン間壁内で収まり、外部に垂れにくくなり、従来よりも少ない量のワニスで巻線の端線の固定を行い、浮き線の発生を防止することができる。
また、前述のように浮き線の発生の防止をすることができることにより、ワニス硬化後にワニスを再供給する再作業を省くことができる。また、少量のワニスで端線の固定保持を行うことができるため、従来のようなワニス垂れを防止し、歩留まりの向上となる。
Since the resolver stator structure according to the present invention is configured as described above, the following effects can be obtained.
That is, since the terminal pin wall is formed in the varnish storage recess provided in the terminal pin holding portion in a state of partitioning the terminal pins, the varnish storage recess is subdivided by each terminal pin wall. Even when the annular stator is inclined after the varnish is supplied and undergoes a drying process, the varnish will fit within the wall between the terminal pins and will not easily sag outside. The wire can be fixed to prevent floating lines.
In addition, since the occurrence of floating lines can be prevented as described above, it is possible to omit rework for re-supplying the varnish after the varnish is cured. In addition, since the end line can be fixed and held with a small amount of varnish, it is possible to prevent the varnish from sagging as in the conventional case and to improve the yield.
本発明は、各端子ピンの周囲に壁によって囲まれた複数のワニス溜り用凹部を形成し、各巻線の端線を各端子ピンにからげてワニス処理した場合におけるワニスからの浮き線の発生を防止するようにしたレゾルバステータ構造を提供することを目的とする。 The present invention forms a plurality of varnish storage recesses surrounded by walls around each terminal pin, and generates a floating line from the varnish when the end line of each winding is tangled to each terminal pin and varnished It is an object of the present invention to provide a resolver stator structure that prevents the above.
