Description

[Detailed description of the invention] The present invention relates to an electrical component box in which electrical components for operation control are installed in an outdoor unit of a separate type air conditioner.
The feature is that each electrical component can be easily installed.

The outdoor unit of an air conditioner is equipped with a compressor, fan, etc., which is the power source for operation, so it is necessary to install a capacitor, which is an electrical component to start the motor of these devices, as well as at least an overcurrent relay, a magnetic relay, and a terminal board. etc. must be installed.

By the way, in the conventional system, the electrical components mentioned above are installed one by one with screws inside the electrical equipment box to protect rainwater, so the work of installing these electrical parts into the electrical equipment box is relatively time-consuming. Therefore, it is not necessarily suitable for mass production, and requires a large number of screw insertion holes and cut-and-raised holes for mounting, and its waterproof properties cannot be said to be good.

In view of the above points, the present invention reduces the number of screws used and facilitates assembly by installing each electrical component in the electrical component box by sandwiching each electrical component between a special frame and a box. This is a simplified version of .

Embodiments of the present invention will be described below based on the drawings.

The electrical equipment box shown in the figure includes a box 1 with an open top and a frame 2 fitted into the box.

The box 1 has a pedestal 3 formed by bulging out a part of the bottom plate 1a approximately in the middle in a trapezoidal shape, and the pedestal 3
A screw insertion hole 4 is opened in the center of the frame.

On the other hand, the frame 2 has a rectangular electric component insertion hole 6 on the left side of the rectangular metal plate 2a, and a circular electric component insertion hole 7 on the right side of the rectangular metal plate 2a. Raise it slightly and place the terminal board installation seat 8.
A screw insertion hole 9 is formed in the center of the terminal board installation seat 8.

Further, at least approximately the center of the metal plate 2a is raised above the grounding area 10.11 where the electric component insertion holes 6 and 7 are formed by the height of the pedestal 3 in the box 1, and the screw insertion hole 13 is raised. A screw seat 12 is formed, and a wall 14 having an arcuate cross section is erected from the edge of the screw seat 12.

The illustrated embodiment is constructed as described above, and the electrical component insertion hole 6 on one side is provided with a cubic magnet relay A corresponding to the shape of the hole, and the electrical component insertion hole 7 on the other side is provided with a cubic magnet relay A corresponding to the shape of the hole. After fitting a cylindrical capacitor C corresponding to the shape of the wall into the constant arc-shaped wall 14 into which the circular overcurrent relay B corresponding to the shape of the hole is inserted, screw 15 is inserted into the frame 2. Penetrates the screw insertion hole 13 and further inserts the box 1
It is screwed into the screw insertion hole 4 of.

In this case, the overcurrent relay B of the magnetic relay A
is equipped with tsuba A' and B' on the lower side of each in advance,
Since these collars A' and B' will pinch the bottom plate 1a of the box by the contact area 10.11 of the frame,
These electrical components A and B will be fixed inside the box 1.

On the other hand, the capacitor C was supported by being sandwiched between the arc-shaped wall 14 and the side wall 1b of the box 1, and was fixed to the upper surface of the terminal board installation seat 8 by screwing another screw 16 into the screw hole 9. By wiring the terminal board and each of the electrical components A, B, and C described above in box 1, each electrical component A, B, C, and D can be connected to the outdoor unit at once through the electrical component box. Can be installed.

Note that the cut gap 17.18 formed between the electrical component insertion holes 6, 7 and the edge of the metal plate 1a is
Since the electric wires can be passed through the holes, it is possible to install the electrical components A and B, which have been wired in advance, into the electrical component insertion holes 6 and 7.

Further, since a gap is formed between the terminal board installation seat 8 and the bottom plate 1b of the box 1, electric wires connected to the terminal board can be routed within the gap.

The electrical equipment box of the present invention, as shown in the above figure, has an open top surface and a pedestal 3 formed by protruding a part of the bottom plate 1a, and has screw insertion holes 4.
electrical component insertion holes 6 and 7 are formed in the grounding areas 10.11 at both ends of the metal plate 2a having an area that can be fitted into the box 1, and these surrounding areas 10.1.
A screw insertion hole 9 is formed in the terminal board installation seat 8 formed on a slightly elevated part between 1 and 1, and a screw insertion hole 13 is formed in the screw seat 12 facing the pedestal 3, and the end edge of the screw seat 12 is formed. Since the frame 2 is formed by standing upright with an arcuate cross section to form the wall 14, it is possible to create an electrical appliance with the flanges A' and B' by simply fixing the frame 2 in the box 1 with the screws 15. Components A and B are placed between the two ground planes 10.11 and the bottom surface 1a of the box 1, and between another cylindrical electrical component C and the arc-shaped wall 14 and the side wall 1b of the box 1. Each can be fixed at the same time, using separate screws 1
Each of the electrical components A, B, and C can be wired and connected to a terminal board fixed to the frame 2 using the wires 6.

In this way, by simply using two screws 15 and 16, you can install the electrical parts A and B necessary for the outdoor unit of the air conditioner.
, C, and D can be easily installed in the electrical equipment box, and there are fewer screw insertion holes and cut-out holes for installation, which improves waterproofness, which has the effect of improving mass production capacity of air conditioners. be.
