Description

本発明は、電動圧縮機に係るもので、特に密閉容器に装着したターミナルを保護する保護部材の改良に関する。   The present invention relates to an electric compressor, and more particularly to an improvement in a protective member that protects a terminal attached to a sealed container.

一般に、電動圧縮機は密閉容器内に電動機構部と、この電動機構部により作動される圧縮機構部とが収納され、当該密閉容器にはターミナルが装着され、このターミナルを介して前記電動機構部に通電して圧縮機構部を作動させる。そして、導入管により圧縮機構部に気体(通常は冷媒)を導入して圧縮すると共に、密閉容器内に吐出された高圧気体を吐出管により外部に取り出すようにしてある。   In general, an electric compressor has an electric mechanism portion and a compression mechanism portion operated by the electric mechanism portion housed in a sealed container, and a terminal is attached to the airtight container, and the electric mechanism portion is connected via the terminal. To actuate the compression mechanism. A gas (usually a refrigerant) is introduced into the compression mechanism by the introduction pipe and compressed, and the high-pressure gas discharged into the sealed container is taken out to the outside through the discharge pipe.

前記ターミナルは、密閉容器外に位置している外部電極に電源からのコード端子が接続されるため、当該電気接続部が外部に露出してしまう。このように電気接続部が外部に露出していると、塵や埃が付着し或は水分が付着して絶縁性の低下や通電不良等を引き起こすことがある。   In the terminal, since a cord terminal from a power source is connected to an external electrode located outside the sealed container, the electrical connection portion is exposed to the outside. When the electrical connection portion is exposed to the outside as described above, dust or dirt may adhere or moisture may adhere to cause a decrease in insulation, poor conduction, or the like.

このような事態に対処するために、従来ターミナルの外部電気接続部を保護するようにした技術が特許文献1、2等に開示されている。

図6に示すように鋼板製のターミナルフェンス1と、このターミナルフェンス1に弾性的に嵌着する合成樹脂製のターミナルカバー2とからなる保護部材でターミナル3を保護する場合は、ターミナルフェンス1の側部に立ち上げて形成された複数の受止片4、5、6の内側にターミナルカバー2の側壁部分2aを嵌着すると共に、ターミナルフェンス1の端部に対設した係止片7、8の係合孔7a、8aにターミナルカバー2の端壁の下部に形成した突起2b、2cをそれぞれ嵌合係止することによりターミナルカバー2を取り付ける構成になっている。   As shown in FIG. 6, when the terminal 3 is protected by a protective member comprising a steel terminal fence 1 and a synthetic resin terminal cover 2 that is elastically fitted to the terminal fence 1, The side wall portion 2a of the terminal cover 2 is fitted inside the plurality of receiving pieces 4, 5 and 6 formed by being raised on the side portion, and the locking piece 7 provided opposite to the end portion of the terminal fence 1; The terminal cover 2 is attached by fitting and locking projections 2b and 2c formed on the lower portion of the end wall of the terminal cover 2 into the engagement holes 7a and 8a of the eight.

しかしながら、上記ターミナルフェンス1にターミナルカバー2を落とし込んで嵌着する際には、図8(a)に示すようにターミナルカバー2の側壁部分2aの下端がターミナルフェンス1の受止片4等(受止片5、6を含む、以下同じ)の上端にぶつかって取付作業性が低下する問題があり、又図8(b)に示すように側壁部分2aと受止片4等との嵌合部において隙間S1が生じ、この隙間S1から水が浸入する懸念があり、更に側壁部分2aの下端とターミナルフェンス1の基板上面との間に隙間S2が生じてガタが生じ易くなり、異音も発生する等の問題があった。
尚、前記受止片4、5に嵌着する側壁部分2aの内側には、図7に示すようにストッパ用突起2cがそれぞれ設けられており、これらの突起2cの下端がターミナルフェンス1の基板上面に当接してストッパ機能を果たすようにしてある。
However, when the terminal cover 2 is dropped and fitted into the terminal fence 1, the lower end of the side wall portion 2 a of the terminal cover 2 is attached to the receiving piece 4 or the like (receiving member) of the terminal fence 1 as shown in FIG. There is a problem that the mounting workability is lowered by hitting the upper end of the stopper pieces 5 and 6 (the same applies hereinafter), and the fitting portion between the side wall portion 2a and the receiving piece 4 or the like as shown in FIG. There is a concern that water may enter through the gap S1, and further, a gap S2 is generated between the lower end of the side wall portion 2a and the upper surface of the terminal fence 1, and noise is generated. There was a problem such as.
7, stopper projections 2c are provided on the inner side of the side wall portion 2a fitted to the receiving pieces 4, 5, respectively, and the lower ends of these projections 2c are the substrate of the terminal fence 1. A stopper function is achieved by contacting the upper surface.

本発明は、上記従来のターミナル保護部材の問題を全て解決するためになされ、ターミナルカバーの取付作業の向上と、ターミナルフェンスに対する嵌合係止部で隙間が生じないようにした電動圧縮機のターミナル保護部材を提供することを目的とする。   The present invention is made in order to solve all the problems of the conventional terminal protection member described above, and is an improved terminal cover mounting operation, and a terminal of an electric compressor in which no gap is generated at a fitting locking portion with respect to the terminal fence. It aims at providing a protection member.

上記の目的を達成するための手段として、本発明の請求項1は、電動機構部と、この電動機構部により作動される圧縮機構部とを収納した密閉容器に、前記電動機構部へ通電するためのターミナルが装着され、当該ターミナルの外部電気接続部を保護するためにターミナルフェンスと、このターミナルフェンスに嵌着するターミナルカバーとからなる保護部材が前記密閉容器の上部蓋体に取り付けられた電動圧縮機において、前記ターミナルカバーは、前記ターミナルフェンスに立ち上げた受止片の内側に嵌合係止する側壁部分を備えており、この側壁部分の外側下端部に内向きに傾斜する傾斜面が形成された電動圧縮機のターミナル保護部材を特徴とする。 As means for achieving the above object, claim 1 of the present invention energizes the electric mechanism portion in a sealed container containing the electric mechanism portion and a compression mechanism portion operated by the electric mechanism portion. A protective member comprising a terminal fence and a terminal cover fitted to the terminal fence is attached to the upper lid of the sealed container to protect the external electrical connection portion of the terminal. In the compressor, the terminal cover includes a side wall portion fitted and locked inside a receiving piece raised on the terminal fence, and an inclined surface inclined inwardly is formed at an outer lower end portion of the side wall portion. The terminal protection member of the formed electric compressor is characterized.

本発明の請求項2は、請求項1の電動圧縮機のターミナル保護部材において、前記ターミナルカバーの側壁部分は、ターミナルフェンスの受止片に嵌合した際に生じる隙間を閉塞するための突起部が設けられ、この突起部の下方に前記傾斜面が形成されたことを特徴とする。   According to a second aspect of the present invention, in the terminal protection member of the electric compressor according to the first aspect, the side wall portion of the terminal cover is a projection for closing a gap generated when the terminal cover is fitted to the receiving piece of the terminal fence. And the inclined surface is formed below the protrusion.

本発明の請求項3は、請求項1又は2の電動圧縮機のターミナル保護部材において、前記ターミナルカバーの側壁部分は、前記ターミナルフェンスの受止片に嵌合係止した際に下端縁がターミナルフェンスの基板上面に当接するように形成されたことを特徴とする。   According to a third aspect of the present invention, in the terminal protection member of the electric compressor according to the first or second aspect, when the side wall portion of the terminal cover is fitted and locked to the receiving piece of the terminal fence, the lower end edge is the terminal. It is characterized by being formed so as to contact the upper surface of the substrate of the fence.

上記請求項1の発明によれば、密閉容器に装着されたターミナルを保護するために、ターミナルフェンスと、このターミナルフェンスに嵌着するターミナルカバーとからなる保護部材を前記密閉容器の上部蓋体に取り付けた電動圧縮機において、前記ターミナルカバーは、ターミナルフェンスに立ち上げた受止片の内側に嵌合係止する側壁部分を備えており、この側壁部分の外側下端部に内向きに傾斜する傾斜面が形成されているので、ターミナルカバーを嵌着する時に前記傾斜面がガイドとなり円滑に誘導されるため、ターミナルカバーの取付作業がし易くなり、その取付作業能率を向上させることができる。 According to the first aspect of the present invention, in order to protect the terminal mounted on the sealed container, a protective member comprising a terminal fence and a terminal cover fitted on the terminal fence is provided on the upper lid of the sealed container. In the attached electric compressor, the terminal cover includes a side wall portion that fits and locks inside the receiving piece raised on the terminal fence, and is inclined inwardly at an outer lower end portion of the side wall portion. Since the surface is formed, when the terminal cover is fitted, the inclined surface serves as a guide and is smoothly guided, so that the terminal cover can be easily attached and the efficiency of the attaching operation can be improved.

上記請求項2の発明によれば、前記ターミナルカバーの側壁部分は、ターミナルフェンスの受止片に嵌合した際に生じる隙間を閉塞するための突起部が設けられ、この突起部の下方に前記傾斜面が形成されているので、ターミナルカバーの嵌着時に受止片との間に生じる隙間を前記突起部によって閉塞することができる。これにより、受止片との間に隙間が生じないため水の浸入を抑えることができる。   According to the second aspect of the present invention, the side wall portion of the terminal cover is provided with a protrusion for closing a gap generated when the terminal cover is fitted to the receiving piece of the terminal fence, and the protrusion is provided below the protrusion. Since the inclined surface is formed, a gap generated between the terminal cover and the receiving piece when the terminal cover is fitted can be closed by the protrusion. Thereby, since a clearance gap does not arise between the receiving pieces, it is possible to suppress entry of water.

上記請求項3の発明によれば、前記ターミナルカバーの側壁部分は、前記ターミナルフェンスの受止片に嵌合係止した際に下端縁がターミナルフェンスの上面に当接するように形成されているため、側壁部分の下端とターミナルフェンスの基板上面との間に生じる隙間を閉塞することができる。これにより、ターミナルカバーのガタが生じ難くなり、異音の発生も抑えることができる。又、側壁部分がストッパ機能を果たすため、従来のように側壁部分の内面にストッパ用突起を設ける必要がなくなる。   According to the third aspect of the present invention, the side wall portion of the terminal cover is formed such that the lower end edge contacts the upper surface of the terminal fence when the terminal cover is fitted and locked to the receiving piece of the terminal fence. The gap generated between the lower end of the side wall portion and the substrate upper surface of the terminal fence can be closed. As a result, the terminal cover is less likely to be loose, and the occurrence of abnormal noise can be suppressed. Further, since the side wall portion serves as a stopper, it is not necessary to provide a stopper projection on the inner surface of the side wall portion as in the prior art.

以下、本発明の実施形態を添付図面に基づいて説明する。
図1は、本発明に係る電動圧縮機のターミナル保護部材の実施形態を示す概略分解斜視図である。図6に示す従来例と実質的に同じ部材は前記と同じ符号を付けて説明する。
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a schematic exploded perspective view showing an embodiment of a terminal protection member of an electric compressor according to the present invention. Components that are substantially the same as those in the conventional example shown in FIG.

図1において、1は鋼板製のターミナルフェンスであり、密閉容器9の蓋体9aの頂部に装着したターミナル3を貫通固定させて蓋体9aに取り付けてある。このターミナルフェンス1は、基板1aの側部に受止片4、5を立ち上げて対設すると共に、受止片4側の側部に小形の受止片6を立ち上げて設け、更に端部には係止片7、8を立ち上げて対設し、これらの係止片7、8には係合孔7a、8aをそれぞれ形成してある。   In FIG. 1, reference numeral 1 denotes a steel plate terminal fence, which is attached to the lid 9 a by penetrating and fixing the terminal 3 attached to the top of the lid 9 a of the sealed container 9. The terminal fence 1 is provided with the receiving pieces 4 and 5 raised on the side portion of the substrate 1a, and the small receiving piece 6 is provided on the side portion on the receiving piece 4 side. Locking pieces 7 and 8 are set up at the part and are opposed to each other, and engaging holes 7a and 8a are formed in these locking pieces 7 and 8, respectively.

2は合成樹脂製のターミナルカバーであり、下方に開口する略ボックス形を呈しており、前記ターミナルフェンス1に落とし込んで着脱可能に嵌着することにより保護部材11(図4)を構成し、この保護部材11によりターミナル3の外部電気接続部を被覆して保護するようにしてある。   Reference numeral 2 denotes a terminal cover made of a synthetic resin, which has a substantially box shape that opens downward. A protective cover 11 (FIG. 4) is formed by dropping the terminal fence 1 and fitting it detachably. The protective member 11 covers and protects the external electrical connection portion of the terminal 3.

このターミナルカバー2は、図2に示すように前記ターミナルフェンス1の受止片4の内側に嵌合係止する側壁部分2aは、外側に突起部12が形成されると共にこの突起部12の下方に傾斜面13が内向きに形成されている。この場合、突起部12も下方に行くにつれて内側に傾斜する傾斜面に形成されている。前記受止片5、6の内側に嵌合係止する側壁部分も同様に、突起部12と傾斜面13とがそれぞれ形成されている。又、ターミナルカバー2の対向する端壁の外側下部には前記係止片7、8の係合孔7a、8aにそれぞれ係合する突起2b、2cがそれぞれ設けられている。更に、ターミナルカバー2の一方の側面部にはコード引き出し部14が設けられ、このコード引き出し部14に対向させてコード受け片15がほぼL字形に突出して設けられ、当該コード受け片15の上端縁に凹部15aが形成されている。   As shown in FIG. 2, the terminal cover 2 has a side wall portion 2 a fitted and locked inside the receiving piece 4 of the terminal fence 1. An inclined surface 13 is formed inwardly. In this case, the protrusion 12 is also formed on an inclined surface that inclines inward as it goes downward. Similarly, the protruding portion 12 and the inclined surface 13 are formed on the side wall portions that are fitted and locked inside the receiving pieces 5 and 6. Protrusions 2b and 2c that engage with the engaging holes 7a and 8a of the locking pieces 7 and 8 are provided on the outer lower portions of the opposing end walls of the terminal cover 2, respectively. Further, a cord lead-out portion 14 is provided on one side surface portion of the terminal cover 2, and a cord receiving piece 15 is provided so as to protrude substantially in an L shape so as to face the cord lead-out portion 14. A recess 15a is formed at the edge.

このように構成されたターミナルカバー2は、前記のようにターミナルフェンス1に落とし込んで弾性的に嵌着するが、この嵌着時において前記受止片4、5、6の内側に嵌合係止する側壁部分2aの下端部には内向きに傾斜する傾斜面13がそれぞれ形成されているため、この傾斜面13がガイド作用をなして円滑に嵌り込むことができる。このため、従来のように側壁部分2aの下端が受止片4等の上端にぶつかってターミナルカバー2の取付作業が妨げられることはなく、その取付作業能率を著しく向上させることができる。   The terminal cover 2 configured in this manner is dropped into the terminal fence 1 and elastically fitted as described above, and is fitted and locked inside the receiving pieces 4, 5, 6 at the time of fitting. Since the inclined surface 13 which inclines inward is formed in the lower end part of the side wall part 2a to perform, this inclined surface 13 can perform a guide effect | action and can fit smoothly. For this reason, unlike the prior art, the lower end of the side wall portion 2a does not collide with the upper end of the receiving piece 4 and the like, and the mounting operation of the terminal cover 2 is not hindered, and the mounting operation efficiency can be significantly improved.

ターミナルカバー2を嵌着すると、図3(b)に示すように側壁部分2aに設けた突起部12が受止片4等に密着するため、従来のように受止片4との間に生じる隙間を塞ぐことができる。即ち、側壁部分2aと受止片4等との間には、隙間が生じないのでこの部分から水が浸入するのを抑えることができる。   When the terminal cover 2 is fitted, the protrusion 12 provided on the side wall portion 2a is in close contact with the receiving piece 4 and the like as shown in FIG. The gap can be closed. That is, since no gap is generated between the side wall portion 2a and the receiving piece 4 and the like, it is possible to prevent water from entering from this portion.

又、側壁部分2aの下端がターミナルフェンス1の基板1aの上面に当接するように形成することにより、従来のように側壁部分2aの下端とターミナルフェンス1の基板1aの上面との間に生じる隙間を塞ぐことができる。このため、ターミナルカバー2のガタが生じ難くなり、異音の発生も抑えることができる。更に、側壁部分2aがストッパ機能を果たすため、従来のように側壁部分の内面にストッパ用突起2cを設ける必要がなくなる。   Further, by forming the lower end of the side wall portion 2 a so as to contact the upper surface of the substrate 1 a of the terminal fence 1, a gap generated between the lower end of the side wall portion 2 a and the upper surface of the substrate 1 a of the terminal fence 1 as in the prior art. Can be blocked. For this reason, the play of the terminal cover 2 is less likely to occur, and the generation of abnormal noise can be suppressed. Furthermore, since the side wall portion 2a serves as a stopper, there is no need to provide the stopper projection 2c on the inner surface of the side wall portion as in the prior art.

図4は、上記のようにターミナルフェンス1にターミナルカバー2を嵌着して保護部材11を形成した状態を示す概略縦断面図である。図1に示すように、前記ターミナル3の導電ピンで形成されている外部電極3aには電源側からの複数(3本)のコード16の先端部に取り付けたコネクタ17が接続され、ターミナルカバー2の内部にはリレー部品18が収納される。   FIG. 4 is a schematic longitudinal sectional view showing a state in which the protective cover 11 is formed by fitting the terminal cover 2 to the terminal fence 1 as described above. As shown in FIG. 1, a connector 17 attached to the distal end portion of a plurality (three) of cords 16 from the power source side is connected to the external electrode 3a formed of the conductive pins of the terminal 3, and the terminal cover 2 The relay part 18 is accommodated in the inside.

ターミナルカバー2の嵌着後に、前記コード16とリレー部品18に接続された複数(2本)のコード19をまとめて一束にした状態で、前記コード引き出し部14から外部に引き出される当該コード群20をコード受け片15の先端部を迂回させて、前記凹部15aに受止させる。これはコード群と蓋体9aとの接触を避けるためである。電動圧縮機の使用時においては密閉容器9が高温となるため、コード群20を高熱から保護する必要がある。   After the terminal cover 2 is fitted, a plurality of (two) cords 19 connected to the cord 16 and the relay component 18 are bundled together, and the cord group is pulled out from the cord drawing portion 14 to the outside. 20 is detoured at the tip of the cord receiving piece 15 and received by the concave portion 15a. This is to avoid contact between the cord group and the lid 9a. When the electric compressor is used, the airtight container 9 becomes high temperature, and thus the cord group 20 needs to be protected from high heat.

図5(a)は、本発明の他の実施形態を示すもので、側壁部分2aの外側下端部に内向きに傾斜する傾斜面13を形成した構成のものである。この場合は、受止片4等の立ち上がり基部の内側にできるR状湾曲部4aの干渉を避けるために、側壁部分2aの外側下端部に内向きの傾斜面13を設けたものである。   FIG. 5A shows another embodiment of the present invention, in which an inclined surface 13 inclined inward is formed at the outer lower end of the side wall portion 2a. In this case, an inwardly inclined surface 13 is provided at the outer lower end of the side wall portion 2a in order to avoid interference of the R-shaped curved portion 4a formed inside the rising base of the receiving piece 4 or the like.

このような構成によれば、図5(b)に示すように側壁部分2aを受止片4等の内側に嵌合係止した時に、側壁部分2aの下端が受止片4等における基部のR状湾曲部4aに干渉されない(ぶつからない)で側壁部分2aの下端をターミナルフェンス1の基板1aの上面に当接させることができる。   According to such a configuration, as shown in FIG. 5B, when the side wall portion 2a is fitted and locked inside the receiving piece 4 or the like, the lower end of the side wall portion 2a is the base portion of the receiving piece 4 or the like. The lower end of the side wall portion 2a can be brought into contact with the upper surface of the substrate 1a of the terminal fence 1 without being interfered with (collision with) the R-shaped curved portion 4a.

このため、従来側壁部分2aの下端とターミナルフェンス1の基板1aの上面との間に生じる隙間S2を塞ぐことができる。これにより、図8(b)に示す隙間S2がなくなるため水の浸入を抑えることができ、又ターミナルカバー2のガタツキが生じ難くなり、異音の発生も抑えることができる。更に、側壁部分2aがストッパ機能を果たすため、従来のように側壁部分の内面にストッパ用突起2cを設ける必要がなくなる。尚、この場合も、傾斜面13によるガイド作用が得られるため、ターミナルカバー2の取付作業がし易くなる。   For this reason, the clearance gap S2 produced between the lower end of the conventional side wall part 2a and the upper surface of the board | substrate 1a of the terminal fence 1 can be plugged up. Thereby, since the gap S2 shown in FIG. 8B is eliminated, the intrusion of water can be suppressed, the backlash of the terminal cover 2 is hardly generated, and the occurrence of abnormal noise can also be suppressed. Furthermore, since the side wall portion 2a serves as a stopper, there is no need to provide the stopper projection 2c on the inner surface of the side wall portion as in the prior art. In this case as well, since the guide action by the inclined surface 13 is obtained, the terminal cover 2 can be easily attached.

本発明は、電動圧縮機のターミナル保護部材として広く適用することが可能であり、ターミナルカバーの側壁部分に僅かな変形を加えるだけで容易に実施することができる。   The present invention can be widely applied as a terminal protection member of an electric compressor, and can be easily implemented only by slightly modifying the side wall portion of the terminal cover.
