欠点がある。 However, with this cable cover mounting device, the vibration of the device body 1 is propagated to the cable cover 4 via the fixed stud 3, and this cable cover 4 acts as a secondary sound source, amplifying the noise level of the device body 1. The disadvantage was that it had a large effect on noise. Furthermore, since the vibration transmitted to the cable cover 4 changes depending on the tightening force of the fixed stud 3, there is a drawback that it is difficult to manage the tightening force.

に防塵用緩衝材２４を介在している。 An embodiment of this invention is shown in FIG. That is, this cable cover attachment device is attached to the device body 8.
A cable connecting conductor 11 is connected to the bushing 9, which is a terminal of the terminal, via a flexible conductor 10, and a cable 12 is further connected to the cable connecting conductor 11, while a soundproof cover stands independently from the device main body 8. A cable cover 15 that covers the cable connection conductor 11 is attached to 14.
6 and 17 are supporting metal fittings, and 18 is a gap adjustment stud. 13 is a sound absorbing material, 19 is a support insulator for supporting the cable connection conductor 11 on the cable cover 15, 20 is its clamp, and 21 is a cable bracket. Further, a flange 22 is provided on the main body 8 of the device around the bushing 9, a rain cover 23 is provided on the cable cover 15 facing the flange 22, and a dustproof cushioning material 24 is interposed therebetween.
このように構成したため、機器本体８の振動は

ブルカバー１５が２次音源になるおそれがなくな
る。 With this configuration, the vibrations of the device main body 8 are only propagated to the cable cover 15 via the elastic materials such as the sound absorbing material 13 and the buffer material 24, and the vibrations are not propagated via a rigid body as in the conventional case. significantly reduced. On the other hand, since the bushing 9 and the cable connection conductor 11 are connected via the flexible conductor 10, vibrations are difficult to propagate. This can prevent vibrations from being transmitted to. Therefore, there is no possibility that the cable cover 15 becomes a secondary sound source.
なお、防塵が不要な場合前記防塵用緩衝材２４

In this case, the gap adjustment stud 18 is adjusted so that the device main body 8 and the cable cover 15 are not in contact with each other. Further, although not shown in the drawings, it is of course possible to form elongated holes on the side of the support metal fitting 17, for example, so that the attachment positional relationship between the cable cover 15 and the support metal fitting 17 can be adjusted.

音化が図れるという効果がある。 As described above, the cable cover mounting device for electrical equipment of this invention attaches the cable cover to the soundproof cover that is independent and separate from the equipment main body, and the connecting conductor for the cable is connected to the terminal of the equipment main body via a flexible conductor. Since the cable cover is connected to the cable cover, the vibration caused by the equipment body can be significantly reduced, which has the effect of reducing noise.
