In the present embodiment, an outdoor unit of an air conditioner will be described as an example. However, the present invention is not limited to this and may be a heat pump unit of a heat pump type hot water heater. And the terminal part 3 is provided in the upper shell 6 of the compressor 2, and the terminal cover is provided so that the terminal part 3 may be covered.
次に、ターミナルカバーの構成について説明する。図２、図３に示すように、本実施の形態のターミナルカバーは上下に２分割され、下部ターミナルカバー４と上部ターミナルカバー５で構成される。 Next, the configuration of the terminal cover will be described. As shown in FIGS. 2 and 3, the terminal cover according to the present embodiment is divided into two parts in the vertical direction, and includes a lower terminal cover 4 and an upper terminal cover 5.
まず、下部ターミナルカバー４の構成について説明する。下部ターミナルカバー４は、端子部３を内部に入れる略円形状の穴部４ｄが設けられており、穴部４ｄに端子部３が収まるように下部ターミナルカバー４を上方から組み付ける。そして、穴部４ｄの周囲を囲
うように凸形状のリブ４ａを設けている。そして穴部４ｄとリブ４ａとの間には排水部４ｃを設けており、端子部３に水がたまることを防止している。
First, the configuration of the lower terminal cover 4 will be described. The lower terminal cover 4 is provided with a substantially circular hole portion 4d into which the terminal portion 3 is inserted, and the lower terminal cover 4 is assembled from above so that the terminal portion 3 is accommodated in the hole portion 4d. And the convex rib 4a is provided so that the circumference | surroundings of the hole part 4d may be enclosed. And the drainage part 4c is provided between the hole part 4d and the rib 4a, and the terminal part 3 is prevented from accumulating water.
また、上部ターミナルカバー５に設けたリード線を取り出すリード線取り出し口５ｃに対向するように壁４ｂが設けられており、リブ４ａの上端部よりは壁４ｂの上端部の方が高い位置となるようにしている。 A wall 4b is provided so as to face the lead wire outlet 5c for taking out the lead wire provided in the upper terminal cover 5, and the upper end portion of the wall 4b is higher than the upper end portion of the rib 4a. I am doing so.
そして、下部ターミナルカバー４を上方から組み付けた後に、リード線９を端子部３へ取り付ける。その後、さらに上部ターミナルカバー５を上方から組み付ける。 Then, after assembling the lower terminal cover 4 from above, the lead wire 9 is attached to the terminal portion 3. Thereafter, the upper terminal cover 5 is further assembled from above.
次に、上部ターミナルカバー５の構成について説明する。上部ターミナルカバー５は、リード線９および端子部３を収納する端子収納部５ａと、リード線９を外部に取り出すリード線取り出し口５ｃが設けられており、さらに、リード線９を下方から上方へ案内し保持するリード線係止爪部５ｄが設けられている。 Next, the configuration of the upper terminal cover 5 will be described. The upper terminal cover 5 is provided with a terminal accommodating portion 5a for accommodating the lead wire 9 and the terminal portion 3, and a lead wire outlet 5c for extracting the lead wire 9 to the outside. Further, the lead wire 9 is moved upward from below. A lead wire locking claw portion 5d for guiding and holding is provided.
また、上部ターミナルカバー５の上部には、圧縮機２に設けられたスタットボルト７を挿入するためのボルト挿入部５ｂが設けられており、ボルト挿入部５ｂにスタットボルト７を挿入した後に、ナット８で止めて、圧縮機２にターミナルカバーを取り付ける。 A bolt insertion portion 5b for inserting a stat bolt 7 provided in the compressor 2 is provided on the upper portion of the upper terminal cover 5, and after inserting the stat bolt 7 into the bolt insertion portion 5b, a nut is inserted. Stop at 8 and attach the terminal cover to the compressor 2.
図４は、圧縮機２の上方正面図である。図４に示すように、圧縮機２の周囲に防音材１０で覆っている。図５は、図４に示すＡＡ断面図であり、図６は、ターミナルカバーを圧縮機２に取り付けた状態で、壁４ｂ方向から見た正面図である。 FIG. 4 is an upper front view of the compressor 2. As shown in FIG. 4, the soundproof material 10 covers the periphery of the compressor 2. FIG. 5 is a cross-sectional view taken along the line AA shown in FIG. 4, and FIG. 6 is a front view as seen from the wall 4 b direction with the terminal cover attached to the compressor 2.
図５に示すように、リード線取り出し口５ｃの上端部よりも、壁４ｂの上端部の方が高い位置となるようにしている。つまり、リード線取り出し口５ｃの出口面積よりも壁４ｂの大きな面積で完全に遮蔽するようにしている。このように構成することにより、リード線取り出し口５ｃの近傍であっても防音材１０を配置することができ、防音性を向上させることができる。 As shown in FIG. 5, the upper end of the wall 4b is positioned higher than the upper end of the lead wire outlet 5c. That is, the area of the wall 4b is completely shielded from the exit area of the lead wire outlet 5c. With this configuration, the soundproofing material 10 can be disposed even in the vicinity of the lead wire outlet 5c, and the soundproofing performance can be improved.
また、図５、図６に示すように、リード線９は、リード線係止爪部５ｄによって下方から上方へ案内されるように保持されている。そして、リード線係止爪部５ｄと壁４ｂとの間に設けられている隙間４ｅは、リード線９が入り込まない程度の大きさになっている。そのため、圧縮機２の振動によってリード線９が外れるのを防止することができる。 Further, as shown in FIGS. 5 and 6, the lead wire 9 is held so as to be guided from below to above by the lead wire locking claw portion 5d. And the clearance gap 4e provided between the lead wire latching claw part 5d and the wall 4b is large enough to prevent the lead wire 9 from entering. Therefore, it is possible to prevent the lead wire 9 from coming off due to the vibration of the compressor 2.
以上のように、本発明に係る圧縮機のターミナルカバーは、空気調和機だけではなくヒートポンプ式給湯機等にも適用することができる。 As described above, the terminal cover of the compressor according to the present invention can be applied not only to an air conditioner but also to a heat pump hot water heater and the like.
