Description

本発明は、レゾルバカバー構造に関し、特に、断面コ字型をなすカバー部材内にレゾルバを収容し、このカバー部材をモータ等の被取付部材に取付けることにより、蓋等を用いることなくレゾルバの防水性を確保するための新規な改良に関する。   The present invention relates to a resolver cover structure, and in particular, a resolver is accommodated in a cover member having a U-shaped cross section, and the cover member is attached to a member to be attached such as a motor, thereby waterproofing the resolver without using a lid or the like. The present invention relates to a new improvement for ensuring the performance.

従来、用いられていたこの種のレゾルバ等をモータに取付け、そのレゾルバ等の防水性を確保するための構成としては、例えば、特許文献１及び２に開示されているモータエンコーダ等を挙げることができる。これらの特許文献１及び２は回転検出器としてエンコーダを用いたものであるが、エンコーダの代わりにレゾルバを用いたものとしては、例えば、図３及び図４で示される構成が用いられている。   Conventionally, this type of resolver or the like used in a motor is mounted on a motor, and as a configuration for ensuring the waterproof property of the resolver or the like, for example, a motor encoder disclosed in Patent Documents 1 and 2 can be cited. it can. In these Patent Documents 1 and 2, an encoder is used as a rotation detector, but the configuration shown in FIG. 3 and FIG. 4 is used as an example using a resolver instead of the encoder.

すなわち、図３において符号１で示されるものはモータ等のハウジングであり、このハウジング１の保持用凹部２内にはレゾルバ３が設けられ、このレゾルバ３のロータ４には、モータ等の軸５が接続されている。
前記ハウジング１の開口６には、Ｏリング７を介して蓋８が設けられ、この蓋８の一部に形成された案内孔９にはレゾルバ３からの信号線１０が貫通して外部に導出されている。
前記案内孔９には樹脂ポッティング等による封止部１１が形成され、レゾルバ３に対する防水性が得られるように構成されている。 That is, a reference numeral 1 in FIG. 3 is a housing such as a motor, and a resolver 3 is provided in a holding recess 2 of the housing 1. A rotor 4 of the resolver 3 is provided with a shaft 5 such as a motor. Is connected.
The opening 6 of the housing 1 is provided with a lid 8 through an O-ring 7, and a signal line 10 from the resolver 3 passes through a guide hole 9 formed in a part of the lid 8 and is led out to the outside. Has been.
A sealing portion 11 is formed in the guide hole 9 by resin potting or the like, and is configured to be waterproof to the resolver 3.

また、図４は他の従来構成を示すもので、図３と同一又は同等部分には同一符号を付し、その説明は省略すると共に、図３とは異なる部分についてのみ説明する。
すなわち、ハウジング１の保持凹部２に連通して連通孔２０が形成され、この連通孔２０は前記ハウジング１に接続された図示しないモータ等に連通し、レゾルバ３の信号線１０が前記モータ側に接続されている。 FIG. 4 shows another conventional configuration. The same reference numerals are given to the same or equivalent parts as those in FIG.
That is, a communication hole 20 is formed in communication with the holding recess 2 of the housing 1, and this communication hole 20 communicates with a motor (not shown) connected to the housing 1, and the signal line 10 of the resolver 3 is connected to the motor side. It is connected.

従来のレゾルバカバー構造は、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、図３の従来構成の場合、レゾルバを防水構造とするために、保持用凹部にＯリングを介して蓋を設け、封止部によって蓋の案内孔を封止しなければならず、Ｏリング及び封止部の劣化等により、防水構造を維持することは極めて困難なことであった。
また、図４の従来構成の場合、図３の従来構成と同様に蓋を設けなければならず、防水性の維持が難しく、かつ、ハウジングに形成した連通孔に信号線を貫通させなければならず、組立時の作業が複雑となっていた。 Since the conventional resolver cover structure is configured as described above, the following problems exist.
That is, in the case of the conventional configuration in FIG. 3, in order to make the resolver waterproof, a lid is provided in the holding recess via the O-ring, and the guide hole of the lid must be sealed by the sealing portion. It has been extremely difficult to maintain a waterproof structure due to deterioration of the ring and the sealing portion.
In the case of the conventional configuration of FIG. 4, a lid must be provided in the same manner as in the conventional configuration of FIG. 3, and it is difficult to maintain waterproofness, and the signal line must be passed through a communication hole formed in the housing. The work at the time of assembly was complicated.

本発明によるレゾルバカバー構造は、断面コ字型をなし保持用凹部を有するカバー部材と、前記カバー部材に埋設された複数の入出力用端子と、前記保持用凹部の周縁に形成された輪状突条部と、前記保持用凹部内に設けられたレゾルバと、前記レゾルバに設けられた複数の端子ピンと、を備え、前記入出力用端子と前記端子ピンとは互いに接続され、前記輪状突条部の外周面をインロー部として前記カバー部材を被取付部材に取付ける構成であり、また、前記輪状突条部の外周面には、Ｏリングが設けられている構成であり、また、前記レゾルバのステータのステータ外周面と、前記ステータに設けられた絶縁カバーの端子保持部の端子保持部外周面と、が、前記保持用凹部の内壁面に接触している構成であり、また、前記内壁面に形成された段部に前記ステータが位置している構成である。   The resolver cover structure according to the present invention includes a cover member having a U-shaped cross section, a holding recess, a plurality of input / output terminals embedded in the cover member, and a ring-shaped protrusion formed on the periphery of the holding recess. A strip portion, a resolver provided in the holding recess, and a plurality of terminal pins provided in the resolver, wherein the input / output terminal and the terminal pin are connected to each other, and the ring-shaped protrusion portion The cover member is attached to the attached member with the outer peripheral surface as an inlay portion, and the outer peripheral surface of the ring-shaped ridge portion is provided with an O-ring, and the stator of the resolver The stator outer peripheral surface and the terminal holding portion outer peripheral surface of the terminal holding portion of the insulating cover provided on the stator are in contact with the inner wall surface of the holding recess, and are formed on the inner wall surface. The The stator step portion is configured to positioned.

本発明によるレゾルバカバー構造は、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、断面コ字型をなすカバー部材の保持凹部内にレゾルバを挿入すると、このカバー部材に埋設されている入出力用端子とレゾルバの端子とピンとが接続して導通され、このカバー部材の輪状突条部の外周面を被取付部材に対するインロー部として接続できるため、カバー部材の内側から外側への経路が完全に断たれ、被取付部材との接続のみであるため、簡単な組立てによって完全な防水を得ることができる。
また、従来構成に比べると、組立作業に用いる部品点数が少なく、組立作業を大幅に容易化し、自動組立てを可能にすることができる。 Since the resolver cover structure by this invention is comprised as mentioned above, the following effects can be acquired.
That is, when the resolver is inserted into the holding recess of the cover member having a U-shaped cross section, the input / output terminal embedded in the cover member, the resolver terminal and the pin are connected and conducted, and the ring shape of the cover member Since the outer peripheral surface of the ridge portion can be connected as an inlay portion with respect to the attached member, the path from the inside to the outside of the cover member is completely cut off and only the connection with the attached member is made. Waterproof can be obtained.
Further, compared to the conventional configuration, the number of parts used for the assembly work is small, the assembly work is greatly facilitated, and automatic assembly can be realized.

本発明は、断面コ字型をなすカバー部材内にレゾルバを収容し、このカバー部材をモータ等の被取付部材に取付けることにより、蓋等を用いることなくレゾルバの防水性を確保するようにしたレゾルバカバー構造を提供することを目的とする。   In the present invention, a resolver is accommodated in a cover member having a U-shaped cross section, and the cover member is attached to a member to be attached such as a motor, thereby ensuring the waterproofness of the resolver without using a lid or the like. An object of the present invention is to provide a resolver cover structure.
