BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical component box assembly structure for an outdoor unit, and more particularly to a capacitor mounting structure in an electrical component box.

[0002]

2. Description of the Related Art Conventionally, an electrical component box of an outdoor unit that performs inverter control has a large number of electrical components mounted thereon by integrating control circuits, and wiring is routed vertically and horizontally to connect printed circuit boards and electrical components. It is configured in a state where Generally, a printed circuit board is mounted on the back side wall of the electrical component box in a floating state, and a heat sink for cooling the heat of the GT transistor or the transistor array is mounted on one of the right and left side walls, and the electrical component is mounted on the other side wall. A vent is provided in the box to allow air to flow, and other electrical components, such as capacitors,
After these parts are mounted and the wiring is routed, the wiring is arranged upright from the bottom plate while adjusting the shape of the wiring in the gap. For this reason, especially in the case of large components such as capacitors, when fixing to the bottom plate with mounting screws etc., it may take time to adjust the position, and the installation may be completed with incomplete installation, causing problems such as loosening and vibration during use May occur.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has been made in consideration of the above problem. An object of the present invention is to provide an electrical component box assembly structure.

[0004]

In order to achieve the above object, a tap hole for fixing a capacitor holder at a predetermined position of a bottom plate of an electric component box of an outdoor unit and a flange portion bent upward at a front edge of the bottom plate are formed. A sliding portion extending laterally to the front edge of the capacitor holder having a plurality of bottomed cylindrical holding portions for holding the outer diameter of the capacitor and opening downward with a U-shaped cross section; and a predetermined position on the bottom portion. A mounting hole for fixing to the bottom plate is formed on the bottom plate, the sliding portion is put on a flange at the front edge of the bottom plate, and the flange is slid laterally on the guide to align the mounting position of the capacitor holder. Further, an arm for holding a wiring or the like drawn out from the electrical box is formed on the slide portion of the capacitor holder.

[0005]

According to the above construction, a slide extending laterally to the front edge of a capacitor holder having a plurality of bottomed cylindrical holding portions for holding the outer diameter of the capacitor and having a U-shaped cross section and opening downward. The sliding part is placed on the flange part bent above the front edge of the bottom plate of the electrical component box, and the mounting hole of the bottom of the capacitor holder is inserted into the mounting hole of the bottom part of the capacitor holder while sliding the capacitor holder with the flange part as a guide. by matching the tap hole, easily can be aligned capacitor holder.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of a main part showing the structure of the present invention. A printed wiring board 2 on which electronic components are mounted at regular intervals is provided on the inner side wall of an electrical component box 1 whose top and front are open. The left side wall has a heat sink 5 on which the GT transistor 3 and the transistor array 4 are mounted, and a ventilation opening 7 formed on the left side of the heat sink 5 by being covered with a cover 6. At the front edge of the bottom plate 8 of the electrical component box 1, a flange 9 bent upward is formed, and a capacitor in which the outer diameter of a plurality of capacitors 10 is inserted and held in a bottomed cylindrical holding portion at a predetermined position of the bottom plate 8. 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, and some of them are It is drawn out of the electrical component box 1. When assembling the electrical component box 1, the printed wiring board 2
After attaching the heat sink 5 and the like, respectively, bind the drawn wires together and adjust the shape,
In order to mount the capacitor holder 11 holding the capacitor 10, the capacitor holder may be
The mounting position of 11 is difficult to match. As a countermeasure, a U-shaped slide portion 12 that opens downward in cross section is formed integrally with the front edge of the capacitor holder 11 so as to extend in the lateral direction, and is formed on the front edge flange 9 of the bottom plate 8 of the electrical component box 1. Positioning the capacitor holder 11 in the front-rear direction by putting it on, and sliding the flange 9 with the guide as shown in FIG.
The mounting hole (shown in the figure) formed at a predetermined position on the bottom of the capacitor holder 11 by sliding the
) And a tab formed at a predetermined position on the bottom plate of the electrical component box 1.
Alignment with a hole (not shown) . After alignment, insert a screw through the mounting hole and
Screw the screw into the tap hole to mount the capacitor holder.
It is configured to be fixed to the product box bottom plate.

A sliding portion is attached to the front edge flange 9 of the bottom plate 8.
By placing the wiring 12 drawn out from the printed wiring board 2 or the like to the outside of the electrical component box 1 by covering it, without directly rubbing against the flange 9 at the front edge of the bottom plate 8,
Problems such as damage to the insulating film of the wiring at the tip of the flange 9 can be prevented beforehand. Further, by providing the arm 13 for locking the wiring on the slide portion 12 of the capacitor holder 11 as shown in the figure, the drawn wiring can be reliably held.

[0008]

As described above, in the present invention, a U-shaped slide portion is provided at the front edge of the capacitor holder, which extends in the lateral direction and opens downward in cross section, and slides over the flange at the front edge of the bottom plate. Thus, the mounting of the capacitor holder is facilitated, and the arm for locking the wiring is provided on the slide portion, so that damage to the drawn wiring can be prevented.
