Description

本発明は、電線が接続される端子台を保護する電動機の端子箱に関し、特にその構造に関する。   The present invention relates to a terminal box for an electric motor that protects a terminal block to which an electric wire is connected, and more particularly to its structure.

一般的に、電動機は、電力を供給する電線が接続される端子台を有し、この端子台は端子箱に保護されている。この端子箱は、端子台を収納する端子箱本体と、これの開口部を覆うカバーを有し、端子箱本体とカバーとが接合する接合部に、端子箱の気密性を向上させるシール部材が挿入される例がある。   Generally, an electric motor has a terminal block to which an electric wire for supplying electric power is connected, and this terminal block is protected by a terminal box. This terminal box has a terminal box main body that houses the terminal block, and a cover that covers the opening of the terminal box, and a sealing member that improves the airtightness of the terminal box is formed at the joint where the terminal box main body and the cover are joined. There is an example to be inserted.

下記特許文献１には、端子箱本体とカバーが接合する接合部に、それに適合する形状に形成されたシール部材が挿入され、ネジによりカバーとシール部材とが端子箱本体に取り付けられる端子箱が記載されている。この端子箱においては、ネジの締め付けにより、シール部材がカバーと端子箱本体とに隙間なく密着するので、端子箱の気密性を向上させることができる。   In Patent Document 1 below, there is a terminal box in which a sealing member formed in a shape that fits a joint portion where a terminal box body and a cover are joined, and the cover and the sealing member are attached to the terminal box body by screws. Are listed. In this terminal box, the sealing member is closely attached to the cover and the terminal box main body by tightening the screws, so that the airtightness of the terminal box can be improved.

特開平９−５６１１２号公報JP-A-9-56112

上記特許文献１のように気密性を持つよう構成される端子箱においては、この端子箱の内部と外部とを結ぶような隙間が形成されない。このような隙間がないので、電動機から発生する音が空気を伝搬して端子箱の内部から外部に漏れることはない。しかし、電動機から発生する音は、端子箱自体を透過するので、透過した音が外部に漏れてしまうという問題がある。   In the terminal box configured to have airtightness as in Patent Document 1, a gap that connects the inside and the outside of the terminal box is not formed. Since there is no such gap, sound generated from the electric motor does not propagate through the air and leak from the inside of the terminal box to the outside. However, since the sound generated from the motor passes through the terminal box itself, there is a problem that the transmitted sound leaks to the outside.

本発明の目的は、簡易な構造により、電動機の騒音を減少させることができる電動機の端子箱を提供することにある。   An object of the present invention is to provide a terminal box of an electric motor that can reduce the noise of the electric motor with a simple structure.

本発明は、電線が接続される端子台を保護する電動機の端子箱であって、端子台を収納する端子箱本体と、前記端子箱本体に形成される開口部を覆うカバーと、前記端子箱本体と前記カバーとが接合する接合部に挿入され、端子箱の気密性を向上させるシール部材と、を有し、前記シール部材は、前記開口部を覆う板形状であることを特徴とする。   The present invention relates to a terminal box for an electric motor that protects a terminal block to which an electric wire is connected, a terminal box main body that houses the terminal block, a cover that covers an opening formed in the terminal box main body, and the terminal box A sealing member that is inserted into a joint portion where the main body and the cover are joined to improve the airtightness of the terminal box, and the sealing member has a plate shape that covers the opening.

また、前記カバーを、前記シール部材に対し所定の間隔をあけて設けることができる。   The cover may be provided at a predetermined interval with respect to the seal member.

また、前記カバーと前記シール部材の間に、音を吸収する吸音部材を設けることができる。   A sound absorbing member that absorbs sound can be provided between the cover and the seal member.

また、前記カバーと前記シール部材の間に、熱伝導が良好な熱伝導部材を設けることができる。   Further, a heat conduction member having good heat conduction can be provided between the cover and the seal member.

また、前記カバーの少なくとも一部を凸凹状に形成することができる。   In addition, at least a part of the cover can be formed in an uneven shape.

また、前記開口部を覆う、前記シール部材の少なくとも一部を、凸凹状に形成することができる。   In addition, at least a part of the seal member that covers the opening can be formed in an uneven shape.

また、前記カバーに、他の部品を取り付ける取付部材を貫通させる貫通穴を形成することができる。   Moreover, the through-hole which penetrates the attachment member which attaches another component to the said cover can be formed.

本発明の電動機の端子箱によれば、簡易な構造により、電動機の騒音を減少させることができる。   According to the terminal box of the electric motor of the present invention, the noise of the electric motor can be reduced with a simple structure.

以下、本発明の実施形態を図面に従って説明する。本実施形態に係る電動機の端子箱の構成について、図１から図４を用いて説明する。図１は、本実施形態に係る電動機１０の端子箱１２の概略構成を示す斜視図である。図２は、図１の端子箱１２を示す断面図である。電動機１０は、電力を供給する電線が接続される端子台（図示せず）を有しており、この端子台は端子箱１２に保護されている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. The structure of the terminal box of the electric motor according to the present embodiment will be described with reference to FIGS. FIG. 1 is a perspective view showing a schematic configuration of a terminal box 12 of an electric motor 10 according to the present embodiment. FIG. 2 is a cross-sectional view showing the terminal box 12 of FIG. The electric motor 10 has a terminal block (not shown) to which an electric wire for supplying electric power is connected, and this terminal block is protected by a terminal box 12.

端子箱１２は、端子箱本体１４と、この端子箱本体１４に対し着脱可能なカバー１６を有している。端子箱本体１４は、電動機本体を収容するハウジング（図示せず）に設けられており、例えばアルミダイカストにより電動機本体のハウジングと一体に成形されている。端子箱本体１４は、端子台を収容しており、その端子台を扱う際の作業性を考慮し、端子箱本体１４の上面に開口部２４が形成されている。開口部２４の周囲には、その開口部を縁取るように端子箱本体１４の端部の面がある。この面は、後述するようにカバー１６と接合する面であり、ここを以降、端子箱本体接合面１４ａと記す。   The terminal box 12 includes a terminal box body 14 and a cover 16 that can be attached to and detached from the terminal box body 14. The terminal box main body 14 is provided in a housing (not shown) that accommodates the electric motor main body, and is integrally formed with the housing of the electric motor main body by, for example, aluminum die casting. The terminal box body 14 accommodates a terminal block, and an opening 24 is formed on the upper surface of the terminal box body 14 in consideration of workability when handling the terminal block. Around the opening 24, there is an end face of the terminal box body 14 so as to border the opening. This surface is a surface to be bonded to the cover 16 as will be described later, and this is hereinafter referred to as a terminal box body bonding surface 14a.

カバー１６は、端子箱本体１４の開口部２４を覆う板状の蓋である。カバー１６は、開口部２４に対応する部分が隆起した形状であり、板金より成形されている。カバー１６の外周部には、端子箱本体接合面１４ａに対向し、それに接合するカバー接合面１６ａが形成されている。このカバー接合面１６ａと端子箱本体接合面１４ａを接合させ、カバー１６と端子箱本体１４を固定ボルト２０で締め付けることにより、カバー１６が端子箱本体１４に固定されて開口部２４を覆う。なお、カバー１６は、板金に限らず、開口部２４を覆うことができる構造であれば、例えば端子箱本体１４と同様にアルミダイカストにより成形されてもよい。   The cover 16 is a plate-like lid that covers the opening 24 of the terminal box body 14. The cover 16 has a shape in which a portion corresponding to the opening 24 is raised, and is formed from sheet metal. A cover joint surface 16a is formed on the outer peripheral portion of the cover 16 so as to face the terminal box main body joint surface 14a and to be joined thereto. The cover 16 is fixed to the terminal box body 14 to cover the opening 24 by bonding the cover bonding surface 16a and the terminal box body bonding surface 14a and tightening the cover 16 and the terminal box body 14 with the fixing bolt 20. Note that the cover 16 is not limited to sheet metal, and may be formed by aluminum die casting, for example, in the same manner as the terminal box body 14 as long as the cover 16 can be covered.

端子箱本体接合面１４ａとカバー接合面１６ａが接合する部分、すなわち端子箱本体１４とカバー１６が接合する接合部２２には、端子箱１２の気密性を向上させるシール部材１８が挿入される。シール部材１８は、固定ボルト２０の締め付けによるカバー１６からの圧縮荷重に耐え得る材料、例えば金属からなるガスケットである。シール部材１８は、固定ボルト２０の締め付けにより、端子箱本体接合面１４ａとカバー接合面１６ａに隙間なく密着するので、端子箱１２の気密性が向上する。   A seal member 18 for improving the airtightness of the terminal box 12 is inserted into a portion where the terminal box main body bonding surface 14a and the cover bonding surface 16a are bonded, that is, a bonding portion 22 where the terminal box main body 14 and the cover 16 are bonded. The seal member 18 is a gasket made of a material that can withstand a compressive load from the cover 16 when the fixing bolt 20 is tightened, for example, a metal. Since the sealing member 18 is tightly adhered to the terminal box main body joint surface 14a and the cover joint surface 16a by tightening the fixing bolt 20, the airtightness of the terminal box 12 is improved.

シール部材１８は、接合部２２を外周部とする例えば平板形状であり、開口部２４を覆う形状である。上述したように開口部２４に対応する、カバー１６の部分が隆起しているので、開口部２４を覆う部分は、シール部材１８と、これに対し所定の間隔をあけて配置されたカバー１６とにより構成される。この構成は、カバー１６とシール部材１８との間の間隔に空気の層である中空部２６が形成されているので、いわゆる中空二重構造となっている。中空二重構造は遮音性が良好なので、そこを透過する音が減少し、電動機１０の騒音を減少させることができる。なお、開口部２４を覆う部分が、カバー１６とシール部材１８を隙間なく重ねた単なる二重構造であってもよい。物質の質量とその物質の遮音性能が比例関係にあるという質量則によれば、開口部２４を覆う部分をカバー１６のみから二重構造にして、その部分の板厚を大きく、すなわち質量を大きくすると、それにともない遮音性が向上するので、電動機１０の騒音を減少させることができる。   The seal member 18 has, for example, a flat plate shape with the joint portion 22 as an outer peripheral portion, and a shape that covers the opening 24. As described above, since the portion of the cover 16 corresponding to the opening 24 is raised, the portion covering the opening 24 includes the seal member 18 and the cover 16 disposed at a predetermined interval with respect to the seal member 18. Consists of. This configuration has a so-called hollow double structure because the hollow portion 26 that is an air layer is formed in the space between the cover 16 and the seal member 18. Since the hollow double structure has good sound insulation, the sound transmitted therethrough is reduced, and the noise of the electric motor 10 can be reduced. Note that the portion covering the opening 24 may have a simple double structure in which the cover 16 and the seal member 18 are overlapped without a gap. According to the mass rule that the mass of the substance and the sound insulation performance of the substance are proportional to each other, the portion covering the opening 24 is made a double structure from only the cover 16, and the thickness of the portion is increased, that is, the mass is increased. Then, since sound insulation improves with it, the noise of the electric motor 10 can be reduced.

また、本実施形態のようにシール部材１８の形状を、開口部２４を覆う板形状にすることにより、シール部材１８を接合部２２に適合する形状になるように中抜き加工する必要がなくなるので、その工程を省くことができる。また、中抜き加工により中抜きされた金属片を無駄に廃棄することがなくなる。   Moreover, since the shape of the seal member 18 is a plate shape that covers the opening 24 as in the present embodiment, it is not necessary to punch the seal member 18 so as to have a shape suitable for the joint portion 22. The process can be omitted. Moreover, the metal piece hollowed out by the hollowing process is not wasted.

また、本実施形態のようにシール部材１８の形状を、開口部２４を覆う板形状にすることにより、端子箱本体１４とシール部材１８に囲われた気密性を有する空間が形成される。つまり、その空間は、それを囲う構成にカバー１６が含まれることなく形成される。このような構成を生かした端子箱１２の一例を、図３を用いて説明する。図３は、図２においてカバー１６に貫通穴１６ｂが形成されたときの端子箱１２を示す断面図である。カバー１６には、貫通穴１６ｂが形成され、それと同軸にナット２８が配置されている。貫通穴１６ｂは、他の部品を取り付ける取付部材、例えばボルトが貫通する穴である。他の部品を取り付けるボルトを、貫通穴１６ｂに貫通させるようにナット２８に締め込むことにより、他の部品をカバー１６に取り付けることができる。このような貫通穴１６を有するカバー１６が端子箱本体１４に固定されていても、カバー１６の状態に関係なく気密性を有する空間が形成されるので、端子箱１２内の気密性を保持することができる。   Further, by forming the seal member 18 in a plate shape that covers the opening 24 as in the present embodiment, an airtight space surrounded by the terminal box body 14 and the seal member 18 is formed. That is, the space is formed without the cover 16 being included in the surrounding structure. An example of the terminal box 12 utilizing such a configuration will be described with reference to FIG. FIG. 3 is a cross-sectional view showing the terminal box 12 when the through hole 16b is formed in the cover 16 in FIG. A through hole 16b is formed in the cover 16, and a nut 28 is arranged coaxially therewith. The through hole 16b is a hole through which an attachment member for attaching another component, for example, a bolt passes. The other parts can be attached to the cover 16 by tightening the bolts for attaching the other parts to the nut 28 so as to penetrate the through holes 16b. Even if the cover 16 having such a through hole 16 is fixed to the terminal box body 14, a space having airtightness is formed regardless of the state of the cover 16, so that the airtightness in the terminal box 12 is maintained. be able to.

次に、電動機１０の騒音をさらに減少させることができる構成について、図４に従って説明する。図４は、図２においてカバー１６とシール部材１８の間の間隔に吸音部材３０が設けられたときの端子箱１２を示す断面図である。カバー１６とシール部材１８の間の間隔には、音を吸収する吸音部材３０が設けられている。吸音部材３０は、多孔質材料からなる部材であり、例えば発泡樹脂材（発泡スチロール）、綿状のガラス繊維であるグラスウールである。吸音部材３０により、そこを伝搬する音のエネルギが吸収されるので、電動機１０の騒音を減少させることができる。   Next, a configuration that can further reduce the noise of the electric motor 10 will be described with reference to FIG. FIG. 4 is a cross-sectional view showing the terminal box 12 when the sound absorbing member 30 is provided in the space between the cover 16 and the seal member 18 in FIG. A sound absorbing member 30 that absorbs sound is provided in the space between the cover 16 and the seal member 18. The sound absorbing member 30 is a member made of a porous material, for example, a foamed resin material (foamed polystyrene) or glass wool that is a cotton-like glass fiber. Since the sound absorbing member 30 absorbs the energy of sound propagating therethrough, the noise of the electric motor 10 can be reduced.

続いて、別の態様の端子箱１２について図５に従って説明する。図５は、本実施形態に係る電動機１０の別の端子箱１２の概略構成を示す断面図である。なお、上記実施形態と同様の構成についての詳細な説明は省略する。   Next, another embodiment of the terminal box 12 will be described with reference to FIG. FIG. 5 is a cross-sectional view illustrating a schematic configuration of another terminal box 12 of the electric motor 10 according to the present embodiment. A detailed description of the same configuration as in the above embodiment is omitted.

カバー１６の少なくとも一部が凸凹状に形成されている。この凸凹状の形状により、カバー１６の表面積が大きくなるので、端子箱１２内部の熱がカバー１６から放熱されやすくなる。また、カバー１６とシール部材１８の間の間隔には、熱伝導が良好な熱伝導部材３２が設けられている。熱伝導部材３２は、その間隔に充填しやすい部材であり、例えばシリコーンからなる。熱伝導部材３２が間隔に充填されることにより、開口部２４を覆う部分の質量が大きくなり、それにともない遮音性が向上するので、電動機１０の騒音を減少させることができる。また、電動機１０の動作により生じる熱を、熱伝導部材３２がシール部材１８からカバー１６に効率よく伝導して、カバー１６が効率よく放熱するので、電動機１０の放熱量を増大させることができる。   At least a part of the cover 16 is formed in an uneven shape. Due to the uneven shape, the surface area of the cover 16 is increased, so that the heat inside the terminal box 12 is easily radiated from the cover 16. Further, a heat conduction member 32 having good heat conduction is provided in the space between the cover 16 and the seal member 18. The heat conducting member 32 is a member that can be easily filled in the gap, and is made of, for example, silicone. Since the heat conductive member 32 is filled at intervals, the mass of the portion covering the opening 24 is increased, and the sound insulation is improved accordingly, so that the noise of the electric motor 10 can be reduced. Further, since the heat conduction member 32 efficiently conducts heat generated by the operation of the electric motor 10 from the sealing member 18 to the cover 16 and the cover 16 efficiently dissipates heat, the heat radiation amount of the electric motor 10 can be increased.

また、さらに別の態様の端子箱１２について図６に従って説明する。図６は、本実施形態に係る電動機１０のさらに別の端子箱１２の概略構成を示す断面図である。開口部２４を覆う、シール部材１８の少なくとも一部が凸凹状に形成されている。この凸凹状の形状により、シール部材１８の表面積が大きくなるので、端子箱１２内部の熱がシール部材１８に吸熱されやすくなる。また、カバー１６とシール部材１８の間の間隔には、図５に示す端子箱１２と同様に、熱伝導が良好な熱伝導部材３２が設けられている。熱伝導部材３２が間隔に充填されることにより、開口部２４を覆う部分の質量が大きくなり、それにともない遮音性が向上するので、電動機１０の騒音を減少させることができる。また、電動機１０の動作により生じる熱を、シール部材１８が効率よく吸熱し、熱伝導部材３２がカバー１６に効率よく伝導して放熱するので、電動機１０の放熱量を増大させることができる。   Further, another embodiment of the terminal box 12 will be described with reference to FIG. FIG. 6 is a cross-sectional view showing a schematic configuration of still another terminal box 12 of the electric motor 10 according to the present embodiment. At least a part of the seal member 18 that covers the opening 24 is formed in an uneven shape. Due to the uneven shape, the surface area of the sealing member 18 is increased, and thus the heat inside the terminal box 12 is easily absorbed by the sealing member 18. Further, similarly to the terminal box 12 shown in FIG. 5, a heat conduction member 32 having good heat conduction is provided in the space between the cover 16 and the seal member 18. Since the heat conductive member 32 is filled at intervals, the mass of the portion covering the opening 24 is increased, and the sound insulation is improved accordingly, so that the noise of the electric motor 10 can be reduced. Further, since the heat generated by the operation of the electric motor 10 is efficiently absorbed by the seal member 18 and the heat conducting member 32 is efficiently conducted to the cover 16 and radiated, the heat dissipation amount of the electric motor 10 can be increased.

この実施形態においては、カバー１６とシール部材１８の間の間隔に熱伝導部材３２を有する端子箱１２が、カバー１６とシール部材１８のいずれか一方が凸凹状に形成されている構成である場合について説明したが、カバー１６とシール部材１８の両方が凸凹状に形成されていてもよいし、両方とも凸凹状に形成されていなくてもよい。また、端子箱１２がカバー１６とシール部材１８の間の間隔に熱伝導部材３２を有する場合に限らず、その間隔が中空部２６のとき、またはその間隔に吸音部材３０が設けられているときでもよい。   In this embodiment, when the terminal box 12 having the heat conducting member 32 in the space between the cover 16 and the seal member 18 is configured such that either the cover 16 or the seal member 18 is formed in an uneven shape. However, both the cover 16 and the seal member 18 may be formed in an uneven shape, or both may not be formed in an uneven shape. In addition, the terminal box 12 is not limited to the case where the heat conducting member 32 is provided in the interval between the cover 16 and the seal member 18, but when the interval is the hollow portion 26 or when the sound absorbing member 30 is provided in the interval. But you can.

本発明に係る電動機１０の端子箱１２は、上述のように高い遮音性を有するので、静粛な環境が求められる場所の電動機、例えば自動車に搭載される電動機に適用することができる。また、自動車に搭載される電動機に限らず、他の種別の電動機に対しても適用することができる。   Since the terminal box 12 of the electric motor 10 according to the present invention has high sound insulation as described above, it can be applied to an electric motor in a place where a quiet environment is required, for example, an electric motor mounted on an automobile. Further, the present invention can be applied not only to an electric motor mounted on an automobile but also to other types of electric motors.
