図１から図４において、電動圧縮機本体１１０にはこれに電気を供給するガラスターミナル１１５が取付けられている。このガラスターミナル１１５を囲むようにブラケット１２０が固着されている。ブラケット１２０は金属材料のＳＰＨＣのプレス曲げにて作られており、対向する左右２辺に係止孔１２１を有している。   1 to 4, a glass terminal 115 for supplying electricity to the electric compressor main body 110 is attached. A bracket 120 is fixed so as to surround the glass terminal 115. The bracket 120 is made by press bending of SPHC, which is a metal material, and has locking holes 121 on two opposite left and right sides.

ガラスターミナル１１５に電装品１１６が装着された後、電装品１１６を覆う電装品カバー１３０が装着される。この電装品カバー１３０は合成樹脂材料のＰＰＥまたはＰＣまたはＰＰまたはＰＢＴとＡＢＳの混合材により射出成形されている。電装品カバー１３０には、ブラケット１２０に設けた係止孔１２１に対応する位置の内壁面に、係止孔１２１に係合するためのテーパ状の爪部１３１を形成している。   After the electrical component 116 is mounted on the glass terminal 115, the electrical component cover 130 that covers the electrical component 116 is mounted. The electrical component cover 130 is injection-molded with a synthetic resin material such as PPE, PC, PP, or a mixed material of PBT and ABS. In the electrical component cover 130, a tapered claw portion 131 for engaging with the locking hole 121 is formed on the inner wall surface at a position corresponding to the locking hole 121 provided in the bracket 120.

また、電装品１１６に電気を供給するための電源コード１４０を電装品カバー１３０とブラケット１２０の間から外側へ引出すためのコード引出し部１４１が電装品カバー１３０の下側に固設されている。コード引出し部１４１は電装品１１６から電源コード１４０が外れないように電源コード１４０を固定している。さらには、電装品カバー１３０は、この電源コード１４０が引出される場所側と同じ側の内壁面にのみ、爪部１３１の下方に、爪部１３１の高さｈよりも高い高さＨにて、電装品カバー１３０の開口端１３７から背面１３８に向かうリブ形状の突起部１３５を設けている。電装品カバー１３０をブラケット１２０に固定した際に、ブラケット１２０の下端部１２２と電装品カバー１３０の突起部１３５との上下方向の隙間Ｓは、電装品カバー１３０の爪部１３１とブラケット１２０の係止孔１２１との上下方向の隙間Ｔよりも小さくなる構成としている。   Further, a cord lead portion 141 for pulling out a power cord 140 for supplying electricity to the electrical component 116 from between the electrical component cover 130 and the bracket 120 to the outside is fixed to the lower side of the electrical component cover 130. The cord lead-out portion 141 fixes the power cord 140 so that the power cord 140 is not detached from the electrical component 116. Furthermore, the electrical component cover 130 is provided at a height H higher than the height h of the claw portion 131 below the claw portion 131 only on the inner wall surface on the same side as the place where the power cord 140 is pulled out. A rib-shaped protrusion 135 is provided from the open end 137 of the electrical component cover 130 toward the back surface 138. When the electrical component cover 130 is fixed to the bracket 120, the vertical gap S between the lower end portion 122 of the bracket 120 and the protrusion 135 of the electrical component cover 130 is related to the claw portion 131 of the electrical component cover 130 and the bracket 120. The structure is smaller than the vertical gap T with the stop hole 121.

以上のように構成された電装品保護装置について、以下その動作、作用を説明する。   The operation and action of the electrical component protection apparatus configured as described above will be described below.

電装品カバー１３０をブラケット１２０に挿入する際に、テーパ状の爪部１３１が係止孔１２１を設けたブラケット１２０の左右２辺に当たると、電装品カバー１３０の左右両壁面がブラケット１２０の左右２辺に対して外側へ歪み、テーパ状の爪部１３１がブラケット１２０の係止孔１２１に係合され、電装品カバー１３０はワンタッチでブラケット１２０に固定されるので取り付け作業性が良好である。   When the electrical component cover 130 is inserted into the bracket 120, if the tapered claw 131 hits the two left and right sides of the bracket 120 having the locking holes 121, the left and right wall surfaces of the electrical component cover 130 are the left and right sides of the bracket 120. Since the taper claw 131 is engaged with the locking hole 121 of the bracket 120 and the electrical component cover 130 is fixed to the bracket 120 with one touch, the mounting workability is good.

電装品カバー１３０がブラケット１２０に固定された状態において、電装品カバー１３０の下方より出ている電源コード１４０を上方へ引き上げる力が加わった場合、電装品カバー１３０はブラケット１２０に対して上方向へずれる。   In a state where the electrical component cover 130 is fixed to the bracket 120, when a force is applied to pull up the power cord 140 protruding from below the electrical component cover 130, the electrical component cover 130 moves upward with respect to the bracket 120. Shift.

しかしながらブラケット１２０の下端部１２２と電装品カバー１３０の突起部１３５との上下方向の隙間Ｓが、電装品カバー１３０の爪部１３１とブラケット１２０の係止孔１２１との上下方向の隙間Ｔよりも小さいことにより、爪部１３１が係止孔１２１に当たる前に、電装品カバー１３０のリブ形状の突起部１３５とブラケット１２０の下端部１２２が当たる。   However, the vertical gap S between the lower end 122 of the bracket 120 and the protrusion 135 of the electrical component cover 130 is larger than the vertical gap T between the claw 131 of the electrical component cover 130 and the locking hole 121 of the bracket 120. By being small, the rib-shaped protrusion 135 of the electrical component cover 130 and the lower end 122 of the bracket 120 abut before the claw 131 abuts the locking hole 121.

従って、電源コード１４０を上方へ引き上げる際の力を突起部１３５が受け止めることができるため、爪部１３１には係止孔１２１からの力が掛かりにくく、その結果、爪部１３１の欠けを防ぐことができ、電装品カバー１３０が外れにくくなる。   Therefore, since the projection 135 can receive the force when the power cord 140 is pulled upward, the claw 131 is not easily applied with the force from the locking hole 121, and as a result, the claw 131 is prevented from being chipped. The electrical component cover 130 is difficult to be removed.

また、電源コード１４０を斜め上方へ引き上げる外側方向への力が加わると、電装品カバー１３０の壁面がブラケット１２０に対し外側へ歪む。   Further, when an outward force is applied to pull up the power cord 140 obliquely upward, the wall surface of the electrical component cover 130 is distorted outward with respect to the bracket 120.

しかしながら本実施の形態では爪部１３１の高さｈよりも突起部１３５の高さＨを高くしているので、爪部１３１が係止孔１２１に当たる前に、突起部１３５は下端部１２２に確実に当てることができる。   However, in this embodiment, since the height H of the projection 135 is higher than the height h of the claw 131, the projection 135 is securely attached to the lower end 122 before the claw 131 hits the locking hole 121. Can be applied.

さらには、突起部１３５は電装品カバー１３０の開口端１３７から背面１３８に向かうリブ形状をしているので、コード引出し部１４１が固設されている側の電装品カバー１３０の壁面の剛性を上げるため、電源コード１４０を斜め上方へ引き上げる外側方向への力が加わった際の、壁面がブラケット１２０に対し外側へ歪む量を小さく抑えることができ、さらに電装品カバー１３０がブラケット１２０から外れにくくなる。   Furthermore, since the protrusion 135 has a rib shape from the open end 137 of the electrical component cover 130 toward the back surface 138, the rigidity of the wall surface of the electrical component cover 130 on the side where the cord lead portion 141 is fixed is increased. Therefore, when an outward force that pulls the power cord 140 obliquely upward is applied, the amount of distortion of the wall surface to the outside with respect to the bracket 120 can be kept small, and the electrical component cover 130 is not easily detached from the bracket 120. .

また、電装品カバー１３０のリブ形状の突起部１３５を電源コード１４０が出る側の内壁面側にのみ設け、反対側の壁面には設けていないので、この反対側の壁面は剛性が低く、歪みやすいので、電装品カバー１３０をブラケット１２０に挿入する際、硬くて入りづらくなることを回避でき、良好な作業性を維持することができる。   Further, since the rib-shaped protrusion 135 of the electrical component cover 130 is provided only on the inner wall surface on the side where the power cord 140 exits and is not provided on the opposite wall surface, the opposite wall surface has low rigidity and is distorted. Therefore, when the electrical component cover 130 is inserted into the bracket 120, it can be prevented from being hard and difficult to enter, and good workability can be maintained.

以上のように、本発明にかかる圧縮機の電装品保護装置は、電装品カバーの外れる可能性を少なくすることができるとともに、電装品カバーをブラケットに挿入する際の作業性を良くすることが可能となるので、冷蔵庫、エアーコンディショナー、冷凍冷蔵装置等のあらゆる圧縮機の電装品保護装置に適用できる。   As described above, the electrical component protection device for a compressor according to the present invention can reduce the possibility that the electrical component cover will come off, and improve the workability when the electrical component cover is inserted into the bracket. Since it becomes possible, it is applicable to the electrical equipment protection apparatus of all compressors, such as a refrigerator, an air conditioner, and a freezer / refrigerator.
