Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electrical component box assembly structure for an outdoor unit, and more particularly to a capacitor mounting structure inside the electrical component box.

[0002]

[Prior art]

 Conventionally, a large number of electrical components are integrated into the electrical component box of an outdoor unit that performs inverter control, with control circuits integrated, and wiring is laid out vertically and horizontally for connections between printed circuit boards and electrical components. ing. In general, the printed circuit board is mounted in a floating state on the inner side wall of the electrical component box, and the heat sink for air-cooling the heat generation of the GT transistor or transistor array is attached to one of the left and right side walls, and the other side wall. Ventilation holes are provided in the electrical equipment box to allow air to flow.For other electrical parts such as capacitors, after these parts are mounted and the wiring is routed, the shape of the wiring is adjusted in the space, It is installed so as to stand upright from the bottom plate. For this reason, especially for large parts such as capacitors, when fixing them to the bottom plate with mounting screws, etc., it may take time to align them, and the installation may end incomplete, causing loose vibration during use, etc. There are some cases where problems occur.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above conventional problems, and provides an electrical component box assembly structure for an outdoor unit that ensures the alignment and fixing of large components such as capacitors in the assembly of electrical component boxes. With the goal.

[0004]

[Means for Solving the Problems]

 In order to achieve the above purpose, a tap hole for fixing the capacitor holder at a predetermined position on the bottom plate of the electrical equipment box of the outdoor unit and a flange part bent upward at the front edge of the bottom plate are formed to hold the outer diameter of the capacitor. A capacitor holder with multiple bottomed cylindrical holders is formed with a slide part that extends laterally and has a U-shaped cross section, and a mounting hole that secures the bottom plate at a predetermined position on the bottom part. Then, the slide part was placed on the flange on the front edge of the bottom plate, and the flange was slid laterally on the guide to align the mounting position of the capacitor holder. In addition, an arm for holding a wire or the like drawn out from the electrical equipment box is formed on the slide portion of the capacitor holder.

[0005]

[Action]

 According to the above configuration, the slide portion that extends laterally at the front edge of the capacitor holder having a plurality of bottomed cylindrical holding portions that hold the outer diameter of the capacitor and has a U-shaped cross section that opens downward is provided. And slide the capacitor part over the flange part that is bent over the front edge of the bottom plate of the electrical equipment box, slide the capacitor holder laterally using the flange part as a guide, and use the mounting hole of the capacitor holder as the mounting tap for the bottom plate. By aligning, the capacitor holder can be easily aligned.

【Example】

 Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing the structure of the present invention. A printed wiring board 2 on which electronic components are mounted is set up at regular intervals on the inner side wall of an electrical equipment box 1 whose top and front surfaces are open. On the left side wall, a heat sink 5 to which the GT transistor 3, the transistor array 4 and the like are attached, and on the left side thereof, a ventilation opening 7 is formed which is covered with a cover 6. A flange 9 bent upward is formed on the front edge of the bottom plate 8 of the electrical component box 1, and the outer diameters of a plurality of capacitors 10 are inserted and held at predetermined positions on the bottom plate 8 in a cylindrical holding part having a bottom. A capacitor holder 11 is attached. Further, although not shown, wirings are respectively drawn from the printed wiring board 2, the GT transistor 3, the transistor array 4 and the capacitor 10 and are connected and grouped in the electrical component box 1. Some of them are It is pulled out of the electrical component box 1. When assembling the electrical component box 1, after mounting the printed wiring board 2 and the heat sink 5, etc., bind the drawn wires together to shape the shape, and then mount the capacitor holder 11 holding the capacitor 10. Because of the mounting, it may be difficult to align the mounting position of the capacitor holder 11 depending on how the wires are put together. To cope with this, a U-shaped slid portion 12 that opens downward in cross section is formed at the front edge of the capacitor holder 11 so as to extend in the lateral direction, and is covered with the flange 9 at the front edge of the bottom plate 8 so that the front and rear of the capacitor holder 11 are covered. In addition to the positioning in the direction, by sliding the flange 9 as shown in FIG. 2, the mounting hole of the capacitor holder 11 and the mounting tap of the bottom plate are aligned.

By covering the flange 9 at the front edge of the bottom plate 8 with the slide portion 12, the wiring drawn from the printed wiring board 2 and the like to the outside of the electrical component box 1 is crossed over the slide portion 12 It is possible to prevent problems such as damage to the insulating film of the wiring at the tip of the flange 9 without directly rubbing against the flange 9 of the edge. Further, the slide portion 12 of the capacitor holder 11 is provided with the arm 13 for locking the wiring as shown in the figure, whereby the lead-out wiring can be securely held.

[0008]

[Effect of device]

 As described above, according to the present invention, the capacitor holder is provided with the U-shaped slide portion that extends laterally and opens downward in cross section, and slides in the lateral direction over the flange of the front edge of the bottom plate. It is possible to prevent damage to the lead-out wiring in advance by facilitating the attachment of the wire and providing an arm for locking the wiring on the slide part.
