［プロテクター３］
図１はカバー４を圧縮機１のプロテクター３に組み付けする前の状態の斜視図、図２（a）はプロテクター３の斜視図である。ガラスターミナル２を正面から観察する場合の方向を前方向とする。 [Protector 3]
FIG. 1 is a perspective view of a state before the cover 4 is assembled to the protector 3 of the compressor 1, and FIG. 2A is a perspective view of the protector 3. The direction when observing the glass terminal 2 from the front is the forward direction.

プロテクター３は、密閉型圧縮機１の電動要素を起動するためのターミナルの一例としてのガラスターミナル２の近傍に、溶接等により取付けられている。プロテクター３は、取付状態でガラスターミナル２周囲を囲む平坦な主面３ｚ、主面３ｚの上辺に繋がり後方向に延在する天板３ａ、主面３ｚの左右方向の一方（本実施例では右側）に位置し後方向に延在するガイド３ｃ、及び、主面３ｚの左右方向の他方（本実施例では左側）に位置し後方向に延在する対面ガイド３eを有する。   The protector 3 is attached by welding or the like in the vicinity of the glass terminal 2 as an example of a terminal for starting the electric element of the hermetic compressor 1. The protector 3 includes a flat main surface 3z that surrounds the periphery of the glass terminal 2 in an attached state, a top plate 3a that extends to the upper side of the main surface 3z and extends rearward, and one of the main surfaces 3z in the left-right direction (right side in this embodiment). ) And a guide 3c extending in the rearward direction, and a facing guide 3e extending in the rearward direction and positioned on the other of the main surfaces 3z in the left-right direction (left side in this embodiment).

天板３ａは、上下方向に略垂直な面であり、第一の係止孔３ｂを備えている。天板３ａのうち、左右方向の一方側（本実施例では右側）が、左右方向の他方側に比して、より後側に広がった形状であり、この部分に第一の係止孔３ｂが設けられている。天板３ａは、例えば上方からの水滴侵入を抑制したり、カバー４を組み付ける際の位置決めに用いることができる。   The top plate 3a is a surface substantially perpendicular to the vertical direction, and includes a first locking hole 3b. Of the top plate 3a, one side in the left-right direction (right side in the present embodiment) has a shape that extends further to the rear than the other side in the left-right direction, and this portion has a first locking hole 3b. Is provided. The top plate 3a can be used, for example, for suppressing water droplet intrusion from above or for positioning when the cover 4 is assembled.

ガイド３ｃは、左右方向に略垂直な面であり、後端側にマーカ３ｄを有している。マーカ３ｄは、後述するように、カバー４をプロテクター３に組み付けた際に、組み付けが正常に行われているかを目視で確認する効率を向上させるものであり、ガイド３ｃの他の部分と異なる外観を有している（第一のマーカとしての機能を果たす）。例えばマーカ３ｄは、平板上のガイド３ｃに設けた孔であったり、ガイド３ｃの他の部分と異なる色や光沢を持つ部分にすることができる。また、ガイド３ｃは、プロテクター３を組み付ける際の位置決めとして用いることができる。   The guide 3c is a surface substantially perpendicular to the left-right direction and has a marker 3d on the rear end side. As will be described later, the marker 3d improves the efficiency of visually confirming whether or not the cover 4 is assembled normally when the cover 4 is assembled to the protector 3, and has a different appearance from the other parts of the guide 3c. (Acts as a first marker). For example, the marker 3d can be a hole provided in a guide 3c on a flat plate, or a portion having a color or gloss different from other portions of the guide 3c. The guide 3c can be used for positioning when the protector 3 is assembled.

対面ガイド３ｅは、左右方向に略垂直な面であり、ガイド３ｃに対しては、左右方向について、主面３ｚを挟んで対向している。対面ガイド３eは、前端側に設けた第二の係止孔３ｆと、上辺側に設けた突起３ｇを備えている。突起３ｇは、後述するように、ガイド３ｃをカバー４に組み付けた際に、組み付けが正常に行われているかを目視で確認する効率を向上させるものである（第二のマーカとしての機能を果たす）。なお、プロテクター３は、例えば金属で形成できる。   The facing guide 3e is a surface that is substantially perpendicular to the left-right direction, and is opposed to the guide 3c in the left-right direction across the main surface 3z. The facing guide 3e includes a second locking hole 3f provided on the front end side and a protrusion 3g provided on the upper side. As will be described later, the protrusion 3g improves the efficiency of visually confirming whether or not the guide 3c is assembled normally when the guide 3c is assembled to the cover 4 (acts as a second marker). ). In addition, the protector 3 can be formed, for example with a metal.

［カバー４］
図２（ｂ）はカバー４を説明する斜視図、図３は、カバー４の正面図である。図３中、紙面手前に向かう方向が前方向である。
カバー４は、プロテクター３に組み付けた際に第一の係止孔３ｂに係合する第一のツメ４ｂ、ガイド３ｃが挿入される開口４ｃが設けられた右側面４ｄ、対面ガイド３eが挿入される開口４e、電源コード（不図示）を装着可能なコード取付部４ｈ、端子押え部４ｊ、及び、プロテクター３に組み付けた際に主面３ｚに対向する後面４ｚを備える。カバー４は、開口４ｃ，４eを形成するように、筒状の区画をそれぞれ有している。開口４eには、第二の係止孔３ｆに係止する第二のツメ４ｆが設けられている。カバー４は、弾性変形可能ないし可撓性のある材料、例えば合成樹脂で形成できる。 [Cover 4]
FIG. 2B is a perspective view illustrating the cover 4, and FIG. 3 is a front view of the cover 4. In FIG. 3, the direction toward the front of the page is the forward direction.
The cover 4 has a first claw 4b that engages with the first locking hole 3b when assembled to the protector 3, a right side surface 4d provided with an opening 4c into which the guide 3c is inserted, and a facing guide 3e. 4e, a cord attaching portion 4h to which a power cord (not shown) can be attached, a terminal pressing portion 4j, and a rear surface 4z that faces the main surface 3z when assembled to the protector 3. The cover 4 has cylindrical sections so as to form the openings 4c and 4e. The opening 4e is provided with a second claw 4f that is locked to the second locking hole 3f. The cover 4 can be formed of an elastically deformable or flexible material such as a synthetic resin.

開口４ｃ、４ｅは筒状のため、カバー４の内部から区切られた空間であり、カバー４がプロテクター３に正常に取付けられた状態では、開口４ｃ、４eに到達した水滴が、カバー４内部に侵入することを抑制している。   Since the openings 4c and 4e are cylindrical, it is a space partitioned from the inside of the cover 4. When the cover 4 is normally attached to the protector 3, water droplets that have reached the openings 4c and 4e are inside the cover 4. The intrusion is suppressed.

コード取付部４ｈは、カバー４の下方側に設けられている。カバー４の下端が上方に折れ曲がった曲がり部４ｈ１と、主面４ｚとの間の領域に電源コードを係止することで、電源コードの脱落を抑制できる。コード取付部４ｈは、カバー４の外側と連通するが、開口は下方を向いているため、水滴が浸入することを抑制できる。   The cord attachment portion 4 h is provided on the lower side of the cover 4. By locking the power cord in a region between the bent portion 4h1 where the lower end of the cover 4 is bent upward and the main surface 4z, the power cord can be prevented from falling off. Although the cord attachment portion 4h communicates with the outside of the cover 4, the opening faces downward, so that water droplets can be prevented from entering.

端子押え部４ｊは、カバー４の取付時に、ガラスターミナル２に接続する端子に接触又は近接可能な突起である。カバー４が樹脂製等である場合、カバー４取付時に作業者が主面４ｚを前方向に押すとカバー４が変形し、端子押え部４ｊが端子に接触する。これにより、例えばガラスターミナル２に端子が正常に取付けられていない場合に、作業者の押圧力によって取付を行うことができる。   The terminal pressing portion 4j is a protrusion that can contact or approach a terminal connected to the glass terminal 2 when the cover 4 is attached. When the cover 4 is made of resin or the like, when the operator pushes the main surface 4z in the forward direction when the cover 4 is attached, the cover 4 is deformed and the terminal pressing portion 4j comes into contact with the terminal. Thereby, when a terminal is not normally attached to the glass terminal 2, for example, attachment can be performed by an operator's pressing force.

［プロテクター３とカバー４との装着］
図４はカバー４装着状態の斜視図、図５はカバー４挿着状態の断面図、図６はカバー４半挿着状態のカバー４を（ａ）右方向、（ｂ）左方向、から見た図、図７はカバー４挿着状態のカバー４を（ａ）右方向、（ｂ）左方向、から見た図である。
プロテクター３とカバー４は、例えば、図１に示す破線矢印の方向へ突き当て挿入することで組み付けられる。プロテクター３とカバー４とが組み付けられると、主面３ｚ及び後面４ｚ等によって囲まれる空間である、電装品やガラスターミナル２を収納可能な収納室が形成される。 [Installation of protector 3 and cover 4]
4 is a perspective view of the cover 4 attached, FIG. 5 is a cross-sectional view of the cover 4 inserted, and FIG. 6 is a view of the cover 4 in the cover 4 half-inserted state from (a) right direction and (b) left direction. FIGS. 7A and 7B are views of the cover 4 with the cover 4 inserted, as viewed from (a) the right direction and (b) the left direction.
The protector 3 and the cover 4 are assembled by, for example, abutting and inserting in the direction of the broken line arrow shown in FIG. When the protector 3 and the cover 4 are assembled, a storage chamber capable of storing the electrical component and the glass terminal 2, which is a space surrounded by the main surface 3z and the rear surface 4z, is formed.

組み付けとしては、具体的には、まず、カバー４を突き当てていくと、天板３aのうち、第一の係止孔３ｂより後方向の領域、及び、対面ガイド３eのうち、第二の係止孔３ｆより後方向の領域に、第一のツメ４ｂ及び第二のツメ４ｆが接触する。これらの接触により、或る程度、摩擦による抵抗が生じる。この抵抗は、カバー４が弾性変形可能な材料で形成されている場合は、さらに大きくなる。すなわち、カバー４を取付ける作業者は、ツメ４ｂ，４ｆがプロテクター３に接触していることを容易に知覚できる。   Specifically, assembling, first, when the cover 4 is abutted, a second region out of the top guide 3a, the region behind the first locking hole 3b, and the second guide 3e. The first claw 4b and the second claw 4f are in contact with the area in the rear direction from the locking hole 3f. To some extent, these contacts cause frictional resistance. This resistance is further increased when the cover 4 is formed of an elastically deformable material. That is, the operator who installs the cover 4 can easily perceive that the claws 4 b and 4 f are in contact with the protector 3.

この抵抗を上回る力でさらにそこから突き当てると、第一の係止孔３ｂ及び第二の係止孔３ｆに、第一のツメ４ｂ及び第二のツメ４ｆが進入することで抵抗が弱まり、略同時にこれらが係合する。カバー４がプロテクター３に正常に取付けられた状態、本実施例では、第一の係止孔３ｂに第一のツメ４ｂが係合され（図５等参照）、第二の係止孔３ｆに第二のツメ４ｆが係合されている状態、を装着状態と呼称する。また、カバー４がプロテクター３に突き当てているものの、両者が正常に取付けられていない状態、本実施例では、これらツメ４ｂ，４ｆの一方又は両方が孔３ｂ，３ｆそれぞれに係合していない状態、を半装着状態と呼称する。   If the force further exceeds this resistance, the resistance decreases as the first claw 4b and the second claw 4f enter the first locking hole 3b and the second locking hole 3f. These engage at substantially the same time. In a state where the cover 4 is normally attached to the protector 3, in this embodiment, the first claw 4b is engaged with the first locking hole 3b (see FIG. 5 and the like), and the second locking hole 3f is engaged. The state in which the second claw 4f is engaged is referred to as a mounted state. In addition, although the cover 4 is in contact with the protector 3 and the two are not normally attached, in this embodiment, one or both of the claws 4b and 4f are not engaged with the holes 3b and 3f, respectively. The state is referred to as a semi-mounted state.

装着状態では、開口４ｃからガイド３ｃが、開口４eから対面ガイド３ｅの一部が、それぞれカバー４から露出する。特に、開口４ｃからマーカ３ｄが、開口４eから突起３ｇが、それぞれ一部、好ましくは、図７（ａ），（ｂ）に例示するように全部露出する。   In the mounted state, the guide 3c is exposed from the opening 4c, and a part of the facing guide 3e is exposed from the cover 4 from the opening 4e. In particular, the marker 3d from the opening 4c and the protrusion 3g from the opening 4e are partly exposed, preferably all as illustrated in FIGS. 7A and 7B.

半装着状態では、開口４ｃからマーカ３ｄが、開口４eから突起３ｇが、装着状態とは異なる範囲（本実施例では、装着状態より少ない範囲）露出する、又は、マーカ３ｄ及び／又は突起３ｇの全部が隠れる（目視不能となる）。本実施例では、装着状態では、円形の孔として設けたマーカ３ｄは全部が露出し（図７（ａ）等参照）、半装着状態では一部が露出する（図６（ａ）等参照）。また、装着状態では、突起３ｇは露出し（図７（ｂ）等参照）、半装着状態では全部が隠れる（図６（ｂ）等参照）。マーカ３ｄや突起３ｇは、製造公差（加工精度）の観点からは、前後方向で０．１ｍｍ以上、好ましくは０．２ｍｍ以上に亘って設けられると好ましい。作業者の目視のし易さの観点からは、大きい方が好ましく、例えば何れかの方向について２ｍｍ以上であると好ましい。   In the semi-mounted state, the marker 3d from the opening 4c and the protrusion 3g from the opening 4e are exposed in a range different from the mounted state (in this embodiment, a range smaller than the mounted state), or the marker 3d and / or the protrusion 3g Everything is hidden (becomes invisible). In the present embodiment, the marker 3d provided as a circular hole is entirely exposed in the mounted state (see FIG. 7A, etc.), and partly exposed in the semi-mounted state (see FIG. 6A, etc.). . Further, in the mounted state, the protrusion 3g is exposed (see FIG. 7B, etc.), and in the semi-mounted state, the whole is hidden (see FIG. 6B, etc.). From the viewpoint of manufacturing tolerance (processing accuracy), the marker 3d and the protrusion 3g are preferably provided in a lengthwise direction of 0.1 mm or more, preferably 0.2 mm or more. From the viewpoint of ease of visual observation by the operator, a larger one is preferable. For example, it is preferably 2 mm or more in any direction.

ここで、図６（ａ）等に例示するように、開口４ｃを形成する筒状部分の前後寸法は、右側面４ｄに設けられた切り欠４ｄａにより、右側面４ｄの前後寸法より短くなっている。このため、ガイド３ｃ及びマーカ３ｄの前後寸法を右側面４ｄの前後寸法と略同じ又はこれより短くしても、装着時にガイド３ｃやマーカ３ｄがカバー４から露出できる。これにより、ガイド３ｃやマーカ３ｄは、カバー４より後方向に突出せず（カバー４の後端より前側に収まる。）、しかも、左右方向（本実施例では右方向）から目視できる。   Here, as illustrated in FIG. 6A and the like, the front-rear dimension of the cylindrical portion forming the opening 4c is shorter than the front-rear dimension of the right side surface 4d due to the notch 4da provided on the right side surface 4d. Yes. For this reason, even if the front and rear dimensions of the guide 3c and the marker 3d are substantially the same as or shorter than the front and rear dimensions of the right side surface 4d, the guide 3c and the marker 3d can be exposed from the cover 4 during mounting. As a result, the guide 3c and the marker 3d do not protrude rearward from the cover 4 (contain in the front side from the rear end of the cover 4), and can be seen from the left-right direction (right direction in this embodiment).

なお、取付の際、作業者は、装着状態の直前の状態を以て、装着が正常に行われたと判断する（誤解する）場合がある。特に、カバー４を合成樹脂等で形成すると、突き当てていくにつれてツメ４ｂ、４ｆの変形量が漸増し、摩擦による抵抗を漸増する構造となり得る。こうすると、カバー４の取付状態を強固にできる一方、半装着状態が、装着状態の直前の状態として実現されやすく、作業者がより誤解し易くなる虞がある。このため、樹脂性のカバー４に設けた爪４ｂ、４ｆを用いることで取付を強固にしつつ、爪４ｂ、４ｆに接触するガイド３ｃ、３ｅに設けたマーカ３ｄ、３ｆを用いることで半装着状態を装着状態であると作業者が誤認することを抑制でき、より好ましい取付構造を実現できる。   In addition, in the case of attachment, an operator may judge (misunderstood) that mounting was performed normally with the state immediately before a mounting state. In particular, when the cover 4 is formed of a synthetic resin or the like, the amount of deformation of the claws 4b and 4f gradually increases as they abut against each other, and a structure in which resistance due to friction is gradually increased can be obtained. In this case, the attachment state of the cover 4 can be strengthened, while the semi-attached state is easily realized as a state immediately before the attached state, and the operator may be more easily misunderstood. For this reason, the attachment is made strong by using the claws 4b and 4f provided on the resinous cover 4, and the semi-mounted state is obtained by using the markers 3d and 3f provided on the guides 3c and 3e contacting the claws 4b and 4f. Can be prevented from being mistaken by the operator as being in a mounted state, and a more preferable mounting structure can be realized.

図８は、冷蔵庫組み付けの状態の斜視図である。本実施例によれば、マーカ３ｄ又は突起３ｇを左右方向何れかそれぞれから目視できるため、冷蔵庫１０等の機器に圧縮機１を組み付けても、カバー４の装着状態を目視で容易に判別可能である。このため、例えば、圧縮機運転中に振動により半挿入状態となってしまっても、判別がし易い。   FIG. 8 is a perspective view of the refrigerator assembled state. According to the present embodiment, since the marker 3d or the protrusion 3g can be visually observed from either the left or right direction, even if the compressor 1 is assembled to a device such as the refrigerator 10, the mounting state of the cover 4 can be easily determined visually. is there. For this reason, for example, even if the compressor is in a half-inserted state due to vibration during operation, it is easy to determine.

［その他の態様等］
なお、マーカ３ｄとしては、露出する部分の色を目視しやすい赤や黄等にしてもよい。これにより、安価で加工容易なマーカとすることができる。 [Other aspects]
In addition, as the marker 3d, the color of the exposed portion may be red, yellow, or the like that is easily visible. Thereby, it can be set as a cheap and easy-to-process marker.

また、カバー４は、電流が流れる電装部品(図示せず)を収納する空間を、開口４ｃ、４ｅとは区画された空間としている。これにより、開口４ｃ、４eより水、ホコリ、ゴミ、虫等の侵入を防止し、信頼性の高い電装品保護カバーとすることができる。カバー４の組み付けを、螺子等でなくツメにより行うことで、カバー４内に水滴等が浸入することを効果的に抑制できる。   Further, the cover 4 has a space for accommodating an electrical component (not shown) through which a current flows as a space partitioned from the openings 4c and 4e. Thereby, intrusion of water, dust, dust, insects and the like from the openings 4c and 4e can be prevented, and a highly reliable electrical component protective cover can be obtained. By assembling the cover 4 with a claw instead of a screw or the like, it is possible to effectively prevent water droplets or the like from entering the cover 4.

また、本実施例では、目視性を高めるためにマーカ３ｄや突起３ｇにより判別を行うとしたが、単にガイド３ｃの先端や対面ガイド３ｅの先端が目視可能かどうかで判別する構成にしても良い。具体的には、装着状態ではガイド３ｃの先端が開口４ｃから目視可能で、半装着状態ではガイド３ｃの先端が目視不能となるように開口４ｃの切欠きを設計しても良い。   Further, in the present embodiment, the determination is made by the marker 3d and the protrusion 3g in order to improve the visibility, but it may be configured to simply determine whether the tip of the guide 3c or the tip of the facing guide 3e is visible. . Specifically, the notch of the opening 4c may be designed so that the tip of the guide 3c is visible from the opening 4c in the mounted state and the tip of the guide 3c is not visible in the half-mounted state.

また、本実施例では、プロテクター３をカバー４が取り囲むようにして両者が組み付けられる。すなわち、天板３ａ、ガイド３ｃ、及び対面ガイド３ｅの外側に、カバー４の側面や上面が位置するように組み付けられる。そして、孔３ｂはプロテクター３の側に、ツメ４ｂはカバー４の側に設けられている。このように、孔が内側に位置するため、水滴が孔を介して内側に進入することを抑制できる。   In the present embodiment, the protector 3 is assembled with the cover 4 surrounding the protector 3. That is, the cover 4 is assembled so that the side surface and the upper surface of the cover 4 are positioned outside the top plate 3a, the guide 3c, and the facing guide 3e. The hole 3b is provided on the protector 3 side, and the claw 4b is provided on the cover 4 side. Thus, since a hole is located inside, it can suppress that a water droplet approachs inside via a hole.

また、本実施例では、プロテクター３について、第一の孔３ｂ、第二の孔３ｆ、及びマーカ３ｄは、それぞれ異なる方向（本実施例では、それぞれ上、左、右側）に設けられている。すなわち、マーカ３ｄが孔３ｂ、３ｆそれぞれから離れた位置にあるため、何れかが係合していない半装着状態の場合でも、装着状態と同様の露出態様になることを抑制できる。これに対して、例えば突起３ｇのように、何れかの孔に近接した位置にマーカを設けると、この孔以外の孔での係合が正常でない態様の半装着状態が生じると、マーカの露出範囲が装着状態と類似して、区別が困難な虞がある。このため、好ましくは、本実施例のように、それぞれの孔に比較的近接して、マーカを設けると良い。本実施例では、孔の個数と同数のマーカを有しているが、マーカの個数の方が多くても良い。   In the present embodiment, the first hole 3b, the second hole 3f, and the marker 3d of the protector 3 are provided in different directions (upward, left, and right in the present embodiment, respectively). That is, since the marker 3d is located at a position away from each of the holes 3b and 3f, it is possible to suppress an exposure mode similar to that in the mounted state even in a semi-mounted state in which any one is not engaged. On the other hand, if a marker is provided at a position close to one of the holes, such as the protrusion 3g, the marker is exposed when a semi-mounted state in which the engagement at the hole other than the hole is not normal occurs. The range is similar to the wearing state and may be difficult to distinguish. For this reason, it is preferable to provide a marker relatively close to each hole as in this embodiment. In this embodiment, the number of markers is the same as the number of holes, but the number of markers may be larger.

［その他の組み付け方法］
カバー４の組み付けは、本実施例の構造に鑑みると、上記した方法に代えて、次の方法にすることもできる。
対面ガイド３ｅ及び第二の孔３ｆは、プロテクター３の左端に設けられており、天面３ａの第一の孔３ｂは、左右方向の端部以外の位置（例えば中央側）に設けられている。このため、まず、カバー４の第二の爪４ｆを第二の孔３ｆに係合させ、次いで、係合した第二の爪４ｆ及び第二の孔３ｆを軸として回動させ、第１の孔３ｂに向けて第一の爪４ｂを近づける。そして、前方に向けて押圧力を加えて、第一の孔３ｂに第一の爪４ｂを係合させる。 [Other assembly methods]
In view of the structure of the present embodiment, the cover 4 can be assembled in the following method instead of the above method.
The facing guide 3e and the second hole 3f are provided at the left end of the protector 3, and the first hole 3b of the top surface 3a is provided at a position other than the end in the left-right direction (for example, the center side). . For this reason, first, the second claw 4f of the cover 4 is engaged with the second hole 3f, and then the second claw 4f and the second hole 3f that are engaged are rotated about the first hole. The first claw 4b is brought closer to the hole 3b. Then, a pressing force is applied toward the front to engage the first claw 4b with the first hole 3b.

このように組み付け作業を行うと、第二の爪４ｆ及び第二の孔３ｆを軸として、梃子の原理によって第一の孔３ｂに第一の爪４ｂを係合させる工程を比較的小さい力で行うことができる。このような組み付け作業は、対面ガイド３ｅが左右方向の端部に位置していることから、回動軸を確保することが容易となるため行い易い。   When the assembling work is performed in this way, the process of engaging the first claw 4b with the first hole 3b by the principle of the lever with the second claw 4f and the second hole 3f as an axis is performed with a relatively small force. It can be carried out. Such assembling work is easy to perform because the facing guide 3e is located at the end in the left-right direction, so that it is easy to secure the rotation shaft.
