　電動圧縮機は、金属製の容器内に圧縮機と、圧縮機を駆動する電動機とを収容している。圧縮機が運転することによって、内部の冷媒ガスが圧縮されて排出される。金属製の容器は、密閉性を有しており、電動機への電力は、容器の開口部に設けられた電気端子を介して、外部の電源供給部から電動機に供給される。 The electric compressor accommodates the compressor and a motor for driving the compressor in a metal container.

　合成樹脂製のターミナルガードを容器の外表面に設置する際、防水等のシール性を確保する必要がある。そのため、従来、ターミナルガードと容器の外表面とが接触するシール面は、平面形状となっていた。したがって、円筒形状又は球体形状を有する容器に対して平面形状を形成するための機械加工、例えば板金加工などを施している。 When installing a synthetic resin terminal guard on the outer surface of the container, it is necessary to secure sealing performance such as waterproof. Therefore, conventionally, the sealing surface where the terminal guard and the outer surface of the container are in contact has a planar shape. Therefore, machining for forming a planar shape, for example, sheet metal processing, is performed on a container having a cylindrical shape or a spherical shape.
　また、ターミナルガードを容器の外表面に取り付ける際、ターミナルガードの設置方向は、容器の中心方向（容器外表面の法線方向）に向かって取り付けることになる。そのため、固定用ボルトを用いて、ターミナルガードの外側から容器の方向へ固定用ボルトを挿入することが一般的である。そのため、固定用ボルトの一部が容器の内部に貫通してしまう。 Also, when the terminal guard is attached to the outer surface of the container, the installation direction of the terminal guard is to be attached toward the center direction of the container (the normal direction of the outer surface of the container). Therefore, it is common to insert the fixing bolt in the direction of the container from the outside of the terminal guard using the fixing bolt. Therefore, part of the fixing bolt penetrates into the inside of the container.
　また、固定用ボルトによる設置の場合、ターミナルガードと容器の外表面の間に設けられるゴム製等のシール部材は、容器の外表面に対して位置決めできる部材がない。そのため、シール部材は、まずターミナルガード側に貼り付けられて、ターミナルガードと同時に容器の外表面に設置されている。そして、容器の外表面にはフェルト製の防音部材が巻かれるが、防音部材が巻かれた後にターミナルガードとシール部材を設置するため、防音部材がシール部材と容器の外表面との間に挟まれる。その結果、シール部材は、ターミナルガードの外形に収まりにくく、はみ出していた。 Further, in the case of installation by means of fixing bolts, the seal member made of rubber or the like provided between the terminal guard and the outer surface of the container does not have a member which can be positioned with respect to the outer surface of the container. Therefore, the seal member is first attached to the terminal guard side and installed on the outer surface of the container simultaneously with the terminal guard. And a soundproof member made of felt is wound around the outer surface of the container, but the soundproof member is sandwiched between the seal member and the outer surface of the container in order to install the terminal guard and the seal member after the soundproof member is wound. Be As a result, the seal member was hard to fit in the outer shape of the terminal guard and was sticking out.
　本発明は、このような事情に鑑みてなされたものであって、容器の外表面の加工が不要になり、加工の手間を低減することができ、かつ保護部材を容易に容器の外表面へ取付けることが可能な電動圧縮機及び電動圧縮機の製造方法を提供することを目的とする。 The present invention has been made in view of such circumstances, and the processing of the outer surface of the container is unnecessary, the processing time can be reduced, and the protective member can be easily applied to the outer surface of the container. An object of the present invention is to provide an electric compressor that can be mounted and a method of manufacturing the electric compressor.

It has a protruding pin-like protrusion and an opening corresponding to the position of the protrusion and the direction of protrusion, and the protrusion is inserted into the opening to surround the electric terminal.
　この構成によれば、ピン状の突起部が曲面状の容器の外表面から、外表面の法線方向に突出して設けられており、保護部材の開口部が突起部の位置と突出方向に対応して形成されている。そして、突起部を保護部材の開口部に挿入することで、保護部材が容器に取り付けられ、容器の外表面に設けられた電気端子を囲む。したがって、容器の保護部材取付け部分において、外表面に平面部分を形成することなく、曲面のままで、保護部材を取り付けることができることから、加工の手間を低減することができる。 According to this configuration, the pin-like protrusion is provided to project from the outer surface of the curved container in the normal direction of the outer surface, and the opening of the protective member corresponds to the position and the protrusion direction of the protrusion It is formed. And a protective member is attached to a container by inserting a projection part in an opening of a protective member, and the electric terminal provided in the outer surface of a container is surrounded. Therefore, since the protective member can be attached while maintaining the curved surface without forming a flat portion on the outer surface of the protective member attachment portion of the container, the processing time can be reduced.
　本発明の第１態様において、前記突起部は、前記外表面の周方向に沿って二つ設けられ、前記二つの突起部に対応する前記開口部は、前記保護部材の側方向に切り欠かれてもよい。 In the first aspect of the present invention, two of the protrusions are provided along the circumferential direction of the outer surface, and the openings corresponding to the two protrusions are cut out in the lateral direction of the protective member. May be
　この構成によれば、容器の外表面の周方向に沿って二つの突起部が設けられており、その突起部は曲面の法線方向に突出していることから、二つの突起部は曲面の軸線方向から見るとハの字状に広がっている。そして、保護部材の開口部が側方向に切り欠かれていることによって、突起部に保護部材の開口部を挿入しやすい。 According to this configuration, two protrusions are provided along the circumferential direction of the outer surface of the container, and since the protrusions protrude in the normal direction of the curved surface, the two protrusions have an axis of the curved surface. When viewed from the direction, it spreads in a C shape. And since the opening of the protection member is notched in the side direction, the opening of the protection member can be easily inserted into the projection.
　本発明の第１態様において、前記容器の外表面と前記保護部材との間に設置されるシール部材を更に備え、前記突起部は、前記外表面の周方向に沿って設けられた二つの第１突起部と、前記第１突起部に対して前記外表面の軸線方向に設けられた一つの第２突起部とを有し、前記シール部材は、前記第１突起部のうち一方と前記第２突起部とにそれぞれ対応して、前記シール部材を２点支持する二つの第１開口部が形成されてもよい。 In the first aspect of the present invention, the apparatus further comprises a seal member disposed between the outer surface of the container and the protective member, and the projection includes two first members provided along a circumferential direction of the outer surface. And a second projecting portion provided in the axial direction of the outer surface with respect to the first projecting portion, and the sealing member includes one of the first projecting portions and the first projecting portion. Two first openings for supporting the sealing member at two points may be formed respectively corresponding to the two protrusions.
　この構成によれば、シール部材に二つの第１開口部が形成され、シール部材は、第１開口部に挿入された第１突起部と第２突起部によって２点支持されることから、シール部材を容器に取り付けるとき、シール部材は、容器の外表面に対して確実に位置決めされる。 According to this configuration, the two first openings are formed in the seal member, and the seal member is supported at two points by the first projection and the second projection inserted into the first opening. When attaching the member to the container, the seal member is securely positioned relative to the outer surface of the container.
　本発明の第１態様において、前記電気端子の突出方向が、前記容器が設置されるベース部の直線部分に対して斜め方向である場合、前記保護部材は、前記容器に取り付けられたとき、前記ベース部の直線部分に対して平行な面が形成された外表面を有してもよい。 In the first aspect of the present invention, in the case where the projecting direction of the electric terminal is oblique with respect to the linear portion of the base portion on which the container is installed, the protective member is attached to the container. It may have an outer surface in which a plane parallel to the straight portion of the base portion is formed.
　この構成によれば、保護部材が容器に取り付けられたとき、保護部材は、容器が設置されるベース部の直線部分に対して平行な外表面を有することから、ベース部の直線部分と保護部材の外表面とが平行になる。したがって、電気端子の突出方向がベース部の直線部分に対して斜め方向である場合でも、ベース部に対して保護部材を適切に収めることができる。 According to this configuration, when the protective member is attached to the container, the protective member has an outer surface parallel to the linear portion of the base on which the container is installed. Is parallel to the outer surface of Therefore, even when the projecting direction of the electric terminal is oblique to the straight portion of the base portion, the protective member can be properly accommodated in the base portion.
　本発明の第２態様に係る電動圧縮機の製造方法は、容器と、前記容器の外表面に設けられた電気端子と、前記容器の外表面に突出したピン状の突起部と、前記突起部の位置と突出方向に対応した開口部が形成され、前記突起部が前記開口部に挿入されて前記電気端子を囲む保護部材と、前記容器の外表面と前記保護部材との間に設置されるシール部材とを備える電動圧縮機の製造方法であって、前記突起部に前記シール部材を挿入するステップと、前記シール部材が前記突起部に挿入された後、前記容器の外表面に防音部材を巻くステップと、前記防音部材が巻かれた前記容器の前記電気端子にケーブルを結線するステップと、前記電気端子に前記ケーブルが結線された前記容器の外表面に前記保護部材を取り付けるステップとを備える。 A method of manufacturing a motor-driven compressor according to a second aspect of the present invention includes a container, an electric terminal provided on the outer surface of the container, a pin-like protrusion protruding from the outer surface of the container, and the protrusion. An opening corresponding to the position and the direction of projection, and the projection is inserted between the opening and disposed between the protective member surrounding the electric terminal, the outer surface of the container, and the protective member A method of manufacturing a motor-driven compressor including a sealing member, wherein the step of inserting the sealing member into the projection, the insertion of the sealing member into the projection, and a soundproofing member on the outer surface of the container The method further comprises the steps of: winding a cable; connecting a cable to the electrical terminal of the container around which the soundproof member is wound; and attaching the protective member to an outer surface of the container whose cable is connected to the electrical terminal .
　この構成によれば、シール部材が突起部に挿入されて容器の外表面に取り付けられた後、防音部材が容器の外表面に巻かれ、更に電気端子にケーブルが結線される。そして、その後保護部材が容器の外表面に取り付けられる。したがって、シール部材の位置が決まった後に防音部材が設置されることから、シール部材と防音部材の取り合い部分の加工がしやすい。そのため、シール部材が確実に取り付けられることから、保護部材の取り付けも行いやすくなる。従来、防音部材を巻いた後に保護部材と共にシール部材を容器の外表面に取り付けていたため、シール部材が保護部材の外形からはみ出して、組み立てにくかったが、本発明ではそのような不具合が生じづらい。 According to this configuration, after the seal member is inserted into the protrusion and attached to the outer surface of the container, the soundproof member is wound around the outer surface of the container, and the cable is connected to the electrical terminal. The protective member is then attached to the outer surface of the container. Therefore, since the soundproof member is installed after the position of the seal member is determined, it is easy to process the connecting portion of the seal member and the soundproof member. Therefore, since the seal member is securely attached, attachment of the protective member can be facilitated. Conventionally, since the seal member is attached to the outer surface of the container together with the protective member after winding the soundproof member, the seal member protrudes from the outer shape of the protective member and is difficult to assemble, but such a defect hardly occurs in the present invention.
　本発明によれば、容器の外表面の加工が不要になり、加工の手間を低減することができ、かつ保護部材を容易に容器の外表面へ取付けることができる。 According to the present invention, the processing of the outer surface of the container is unnecessary, the processing time can be reduced, and the protective member can be easily attached to the outer surface of the container.

　以下に、本発明に係る実施形態について、図面を参照して説明する。
　まず、電動圧縮機１の構成について説明する。
　電動圧縮機１は、金属製の容器２内に圧縮機と、圧縮機を駆動する電動機などを収容している。圧縮機が運転することによって、内部の冷媒ガスが圧縮されて排出される。金属製の容器２は、密閉性を有しており、電動機への電力は、容器２の開口部に設けられた電気端子３を介して、容器２の外部の電源から電動機に供給される。 Hereinafter, embodiments according to the present invention will be described with reference to the drawings.
First, the configuration of the electric compressor 1 will be described.
The electric compressor 1 contains a compressor, a motor for driving the compressor, and the like in a metal container 2. By operating the compressor, the refrigerant gas inside is compressed and discharged. The metal container 2 has hermeticity, and power to the motor is supplied to the motor from a power supply outside the container 2 through the electric terminal 3 provided at the opening of the container 2.
　容器２は、図５及び図６に示すように、横断面が例えば円筒形状である。円筒形状の軸線方向は、電動圧縮機１が設置されたときの電動圧縮機１の上下方向と一致する。 The container 2 is, for example, cylindrical in cross section as shown in FIGS. 5 and 6. The axial direction of the cylindrical shape coincides with the vertical direction of the motor-driven compressor 1 when the motor-driven compressor 1 is installed.
　電気端子３は、図４及び図６に示すように、容器２の外表面から外側へ突出している。電気端子３の突出方向は、例えば容器２の円筒形状の半径方向、すなわち円筒形状の外表面の法線方向である。電気端子３は、ケーブル（図示せず。）と結線される。ケーブルは、外部の電源から電動圧縮機１の電動機に電力を供給する。 The electrical terminal 3 protrudes outward from the outer surface of the container 2 as shown in FIGS. 4 and 6. The protruding direction of the electrical terminal 3 is, for example, the radial direction of the cylindrical shape of the container 2, that is, the normal direction of the outer surface of the cylindrical shape. The electrical terminal 3 is connected to a cable (not shown). The cable supplies electric power to the motor of the electric compressor 1 from an external power source.
　電動圧縮機１の容器２の外表面には、図１及び図２に示すように、パッキン６を介してターミナルガード５が設けられる。また、ターミナルガード５の設置のため、容器２の外表面には、ボルト４ａ，４ｂ，４ｃが設けられる。 As shown in FIG. 1 and FIG. 2, a terminal guard 5 is provided on the outer surface of the container 2 of the electric compressor 1 via a packing 6. Further, for the installation of the terminal guard 5, bolts 4a, 4b and 4c are provided on the outer surface of the container 2.
　ボルト４ａ，４ｂ，４ｃは、ピン状の突起部の一例であり、図４及び図５に示すように、容器２の外表面から外側へ突出している。ボルト４ａ，４ｂ，４ｃは、容器２の外表面を平面形状に加工することなく、曲面部分にそのまま取り付けられる。ボルト４ａ，４ｂ，４ｃの突出方向は、例えば容器２の円筒形状の半径方向、すなわち円筒形状の外表面の法線方向である。 The bolts 4a, 4b and 4c are an example of pin-like protrusions, and project outward from the outer surface of the container 2 as shown in FIGS. The bolts 4a, 4b and 4c are attached to the curved portion without processing the outer surface of the container 2 into a flat shape. The projecting direction of the bolts 4a, 4b, 4c is, for example, the radial direction of the cylindrical shape of the container 2, that is, the normal direction of the outer surface of the cylindrical shape.
　ターミナルガード５は、保護部材の一例であり、図５に示すように、電気端子３を囲んで、電気端子３を内部に収容する。ターミナルガード５には、図７に示すように、ボルト４ａ，４ｂ，４ｃの位置と突出方向に対応した開口部７ａ，７ｂ，８が形成される。ターミナルガード５を容器２の外表面に設置したときのターミナルガード５の容器２側の面５Ａは、図１０及び図１１に示すように、容器２の外表面の形状に一致する。本実施形態では、ターミナルガード５の面５Ａの横断面は、容器２の軸心Ｏを共通にする円弧形状である。 The terminal guard 5 is an example of a protection member, and as shown in FIG. 5, encloses the electrical terminal 3 and accommodates the electrical terminal 3 therein. As shown in FIG. 7, the terminal guard 5 is formed with openings 7a, 7b, 8 corresponding to the positions and projecting directions of the bolts 4a, 4b, 4c. The surface 5A on the container 2 side of the terminal guard 5 when the terminal guard 5 is installed on the outer surface of the container 2 conforms to the shape of the outer surface of the container 2 as shown in FIGS. 10 and 11. In the present embodiment, the cross section of the surface 5A of the terminal guard 5 has an arc shape in which the axial center O of the container 2 is common.
　パッキン６は、シール部材の一例であり、図１、図２及び図５に示すように、ターミナルガード５と容器２の外表面との間に設置される。パッキン６は、例えばゴム製であり、ターミナルガード５と容器２の外表面との間の防水性を確保する。 The packing 6 is an example of a sealing member, and is disposed between the terminal guard 5 and the outer surface of the container 2 as shown in FIGS. 1, 2 and 5. The packing 6 is made of, for example, rubber, and ensures waterproofness between the terminal guard 5 and the outer surface of the container 2.
　本実施形態によれば、ピン状のボルト４ａ，４ｂ，４ｃが円筒形状の容器２の外表面から、外表面の法線方向に突出して設けられており、ターミナルガード５の開口部７ａ，７ｂ，８がボルト４ａ，４ｂ，４ｃの位置と突出方向に対応して形成されている。そして、ボルト４ａ，４ｂ，４ｃをターミナルガード５の開口部７ａ，７ｂ，８に挿入することで、ターミナルガード５が容器２に取り付けられ、容器２の外表面に設けられた電気端子３を囲んで内部に収容する。したがって、ボルト４ａ，４ｂ，４ｃが円筒形状の外表面にそのまま取り付けられており、容器２のターミナルガード５取付け部分において、外表面に平面部分を形成することなく、曲面のままで、ターミナルガード５を取り付けることができることから、加工の手間を低減することができる。 According to the present embodiment, pin-shaped bolts 4a, 4b, 4c are provided to project from the outer surface of the cylindrical container 2 in the normal direction of the outer surface, and the openings 7a, 7b of the terminal guard 5 are provided. , 8 are formed corresponding to the positions of the bolts 4a, 4b, 4c and the projecting direction. Then, the terminal guard 5 is attached to the container 2 by inserting the bolts 4a, 4b, 4c into the openings 7a, 7b, 8 of the terminal guard 5, and the electric terminal 3 provided on the outer surface of the container 2 is surrounded. To accommodate inside. Therefore, the bolts 4a, 4b and 4c are attached as they are to the cylindrical outer surface, and the terminal guard 5 is attached to the terminal guard 5 of the container 2 without forming a flat portion on the outer surface. Can be attached, which can reduce the processing time.
　次に、ボルト４ａ，４ｂ，４ｃとターミナルガード５について説明する。
　ボルト４ａとボルト４ｂは、容器２の外表面において同一の周方向上に設置される。ボルト４ａとボルト４ｂは、第１突起部の一例である。ボルト４ｃは、ボルト４ａとボルト４ｂに対して、容器２の軸線方向に設けられる。ボルト４ｃは、第２突起部の一例である。本実施形態では、ボルト４ｃは、ボルト４ａとボルト４ｂの間であって、ボルト４ａとボルト４ｂよりも容器２の上方向に設置される。 Next, the bolts 4a, 4b, 4c and the terminal guard 5 will be described.
The bolt 4 a and the bolt 4 b are disposed on the same circumferential direction on the outer surface of the container 2. The bolt 4a and the bolt 4b are examples of the first protrusion. The bolt 4c is provided in the axial direction of the container 2 with respect to the bolt 4a and the bolt 4b. The bolt 4c is an example of a second protrusion. In the present embodiment, the bolt 4c is installed between the bolt 4a and the bolt 4b in the upper direction of the container 2 than the bolt 4a and the bolt 4b.
　ターミナルガード５には、開口部７ａ，７ｂ，８が形成される。開口部７ａ，７ｂは、図７及び図８に示すように、ターミナルガード５の側方に切り欠かれた形状を有している。開口部８は、ターミナルガード５の中心軸上に設けられ、円形状である。ターミナルガード５は、図７～図９に示すように、上部の開口部８と反対側の下部が開放されており、電気端子３に接続されたケーブルは、ターミナルガード５の開放部分を通過するように設置される。 Openings 7 a, 7 b, 8 are formed in the terminal guard 5. The openings 7a and 7b have a shape which is cut out on the side of the terminal guard 5 as shown in FIGS. 7 and 8. The opening 8 is provided on the central axis of the terminal guard 5 and has a circular shape. As shown in FIGS. 7 to 9, the terminal guard 5 is open at the lower side opposite to the upper opening 8, and the cable connected to the electrical terminal 3 passes through the open portion of the terminal guard 5. To be installed.
　ボルト４ａとボルト４ｂは、容器２の外表面の同一周方向上に設けられ、円筒形状の法線方向に突出していることから、ボルト４ａとボルト４ｂは、図５及び図６に示すように、容器２の軸線方向から見るとハの字状に広がっている。すなわち、ボルト４ａの先端部とボルト４ｂの先端部の間隔は、ボルト４ａの基部とボルト４ｂの基部の間隔よりも広い。 The bolt 4a and the bolt 4b are provided on the same circumferential direction of the outer surface of the container 2 and project in the normal direction of the cylindrical shape, so the bolt 4a and the bolt 4b are as shown in FIGS. When viewed from the axial direction of the container 2, it is expanded in a C shape. That is, the distance between the tip of the bolt 4a and the tip of the bolt 4b is wider than the distance between the base of the bolt 4a and the base of the bolt 4b.
　ターミナルガード５を容器２の外表面に取り付ける際、ターミナルガード５の設置方向は、容器２の中心方向（容器２の外表面の法線方向）に向かって取り付けることになる。そのため、ターミナルガード５の開口部７ａ，７ｂが例えば真円形状では、ターミナルガード５を取り付けることができない。本実施形態では、ターミナルガード５の開口部７ａ，７ｂが側方向に切り欠かれていることによって、ボルト４ａ，４ｂにターミナルガード５の開口部７ａ，７ｂが挿入しやすくなっている。なお、開口部７ａ，７ｂは、側方向に長い長円形状でもよい。 When the terminal guard 5 is attached to the outer surface of the container 2, the installation direction of the terminal guard 5 is to be attached toward the center direction of the container 2 (the normal direction of the outer surface of the container 2). Therefore, if the openings 7a and 7b of the terminal guard 5 have a perfect circular shape, for example, the terminal guard 5 can not be attached. In this embodiment, the openings 7a and 7b of the terminal guard 5 are easily inserted into the bolts 4a and 4b by the openings 7a and 7b of the terminal guard 5 being cut out in the side direction. The openings 7a and 7b may have an oval shape that is long in the side direction.
　次に、パッキン６について説明する。
　パッキン６には、図１２に示すように、開口部１１ａ，１１ｂ，１２，１３が形成される。開口部１１ａは、ボルト４ａに対応しており、側方に切り欠きが形成されている。これによって、パッキン６は、ターミナルガード５と同様に、容器２の外表面の法線方向に設置されたボルト４ａとボルト４ｂに対しても取付け可能である。すなわち、開口部１１ａは、側方向に切り欠かれていることから、容器２の外表面にパッキン６が挿入しやすくなっている。 Next, the packing 6 will be described.
In the packing 6, as shown in FIG. 12, openings 11a, 11b, 12, 13 are formed. The opening 11a corresponds to the bolt 4a, and a notch is formed on the side. As a result, the packing 6 can be attached to the bolts 4 a and 4 b installed in the normal direction of the outer surface of the container 2 as well as the terminal guard 5. That is, since the opening 11 a is cut away in the side direction, the packing 6 can be easily inserted into the outer surface of the container 2.
　開口部１１ｂは、ボルト４ｂに対応しており、円形状である。開口部１２は、ボルト４ｃに対応しており、開口部１３側に切り欠きが形成されている。開口部１３は、電気端子３を囲む円形状を有している。開口部１１ｂと開口部１２は、第１開口部の一例である。 The opening 11 b corresponds to the bolt 4 b and is circular. The opening 12 corresponds to the bolt 4c, and a notch is formed on the opening 13 side. The opening 13 has a circular shape surrounding the electrical terminal 3. The opening 11 b and the opening 12 are an example of a first opening.
　パッキン６は、パッキン６が容器２の外表面に取り付けられる際、まず、ボルト４ｂに開口部１１ｂが挿入され、かつ、ボルト４ｃに開口部１２が掛けられる。これによって、パッキン６は、ボルト４ｂとボルト４ｃによって２点支持されることから、パッキン６は、容器２の外表面に対して確実に位置決めされる。そのため、その後の工程、例えば容器２の外表面に防音部材（図示せず。）を巻く工程で、防音部材とパッキン６の取り合い部分の加工がしやすい。 In the packing 6, when the packing 6 is attached to the outer surface of the container 2, first, the opening 11 b is inserted into the bolt 4 b, and the opening 12 is hung on the bolt 4 c. As a result, the packing 6 is supported at two points by the bolt 4 b and the bolt 4 c, so that the packing 6 is reliably positioned with respect to the outer surface of the container 2. Therefore, in the subsequent process, for example, the process of winding a soundproofing member (not shown) around the outer surface of the container 2, processing of the connection portion between the soundproofing member and the packing 6 is easy.
　次に、図１３などを参照して、ターミナルガード５の外形について説明する。
　ここで、電動圧縮機１は、図１３に示すように、容器２の脚部２Ａがベース部１０上に設置される。そして、電気端子３の突出方向Ｅがベース部１０の直線部分Ｌに対して、直交方向ではなく、斜め方向である場合、ターミナルガード５の外表面５Ｂは、ターミナルガード５が容器２に取り付けられたとき、ベース部１０の直線部分Ｌに対して平行な面である。 Next, the outer shape of the terminal guard 5 will be described with reference to FIG. 13 and the like.
Here, as shown in FIG. 13, in the electric compressor 1, the leg portion 2 </ b> A of the container 2 is installed on the base portion 10. Then, when the protruding direction E of the electric terminal 3 is not a perpendicular direction but an oblique direction with respect to the linear portion L of the base portion 10, the terminal guard 5 is attached to the container 2 on the outer surface 5B of the terminal guard 5 When it is parallel to the straight portion L of the base portion 10.
　本実施形態によれば、ターミナルガード５が容器２に取り付けられたとき、ベース部１０の直線部分Ｌとターミナルガード５の外表面５Ｂとが平行になる。したがって、電気端子３の突出方向Ｅがベース部１０の直線部分Ｌに対して垂直方向ではなく斜め方向である場合でも、ベース部１０に対してターミナルガード５を適切に収めることができる。 According to this embodiment, when the terminal guard 5 is attached to the container 2, the linear portion L of the base portion 10 and the outer surface 5 </ b> B of the terminal guard 5 become parallel. Therefore, even when the projecting direction E of the electric terminal 3 is not perpendicular to the straight portion L of the base portion 10 but in an oblique direction, the terminal guard 5 can be properly accommodated in the base portion 10.
　次に、電動圧縮機１におけるターミナルガード５の取り付け方法について説明する。
　まず、図３及び図４に示すように、パッキン６がボルト４ａ，４ｂ，４ｃに挿入される。その後、容器２の外表面に防音部材（図示せず。）が巻かれる。防音部材は、例えばフェルト製である。そして、防音部材が巻かれた容器２の電気端子３にケーブル（図示せず。）を結線する。次に、電気端子３にケーブルが結線された容器２の外表面に対して、図１及び図５に示すように、ターミナルガード５が取り付けられる。ターミナルガード５は、ボルト４ａ，４ｂ，４ｃに対してナット１４が用いられることで固定される。 Next, a method of attaching the terminal guard 5 in the electric compressor 1 will be described.
First, as shown in FIGS. 3 and 4, the packing 6 is inserted into the bolts 4a, 4b, 4c. Thereafter, a soundproof member (not shown) is wound around the outer surface of the container 2. The soundproofing member is made of, for example, felt. Then, a cable (not shown) is connected to the electric terminal 3 of the container 2 in which the soundproof member is wound. Next, as shown in FIG. 1 and FIG. 5, the terminal guard 5 is attached to the outer surface of the container 2 in which the cable is connected to the electric terminal 3. The terminal guard 5 is fixed to the bolts 4a, 4b and 4c by using a nut 14.
　本実施形態によれば、パッキン６がボルト４ａ，４ｂ，４ｃに挿入されて容器２の外表面に取り付けられた後、防音部材が容器２の外表面に巻かれ、更に電気端子３にケーブルが結線される。そして、その後ターミナルガード５が容器２の外表面に取り付けられる。したがって、パッキン６の位置が決まった後に防音部材が設置されることから、パッキン６と防音部材の取り合い部分の加工がしやすい。そのため、パッキン６が確実に取り付けられることから、ターミナルガード５の取り付けも行いやすくなる。従来、防音部材を巻いた後にターミナルガードと共にパッキンを容器の外表面に取り付けていたため、パッキンがターミナルガードの外形からはみ出して、組み立てにくかったが、本実施形態ではそのような不具合が生じづらい。 According to the present embodiment, after the packing 6 is inserted into the bolts 4a, 4b and 4c and attached to the outer surface of the container 2, the soundproof member is wound around the outer surface of the container 2 Wired Thereafter, the terminal guard 5 is attached to the outer surface of the container 2. Therefore, since the soundproofing member is installed after the position of the packing 6 is determined, it is easy to process the connecting portion between the packing 6 and the soundproofing member. Therefore, since the packing 6 is securely attached, the terminal guard 5 can be easily attached. Conventionally, since the packing was attached to the outer surface of the container together with the terminal guard after winding the soundproofing member, the packing was out of the outer shape of the terminal guard and was difficult to assemble, but such a defect hardly occurs in this embodiment.
　なお、本取付け方法は、上述した本実施形態のターミナルガード５や容器２の外表面に限定されない。例えば、従来のようにターミナルガードの取り付け部分において、容器の外表面が平面形状に形成され、かつ、容器の外表面からボルトが突出している場合でも、同様に取り付けることができる。そして、この場合でも、本取付け方法と同一の作用効果を奏する。 In addition, this attachment method is not limited to the outer surface of the terminal guard 5 of this embodiment mentioned above or the container 2. FIG. For example, even if the outer surface of the container is formed in a planar shape at the mounting portion of the terminal guard as in the prior art and the bolt protrudes from the outer surface of the container, the same attachment can be made. Also in this case, the same effect as that of the present mounting method can be obtained.
