Description

[Detailed explanation of the idea] The present invention relates to an electrical component box for an air conditioner.

The electrical equipment box of this type of air conditioner includes relays, transformers,
Various electrical components such as operating capacitors for fans, printed circuit boards, and lamp house assembly parts are stored.

By the way, it is necessary to connect the connector on the electrical component side to the connector on the fan motor side, but conventionally, the connector on the electrical component side has its lead wire fixed to the electrical component box with a fixing band and connected to the electrical component. I pulled it out of the box and connected it to the connector on the motor side.

However, according to this, the connector and lead wire are suspended in the air, which causes the connector and lead wire to collide with or come into contact with the motor due to vibrations, etc., resulting in damage to the connector and melting of the lead wire coating. There were drawbacks.

This invention is an improvement on the above-mentioned drawbacks.
An air conditioner in which the connector on the electrical component side can be fixed simply and easily, and in addition, if the shape and size of the connector changes, only the plate can be replaced to easily mount and fix the connector. The aim is to provide electrical equipment boxes.

The configuration of the present invention will be described below with reference to the embodiments shown in the drawings.

In Figures 1 to 3, 1 is the main body of the air conditioner, 2 is the front panel attached to the front of the main body 1, 3 is the suction port, and 4 is the main body of the air conditioner.
is an air outlet, and 5 is an electrical equipment box arranged and fixed on one side of the air conditioner main body 1. Inside this electrical equipment box 5 are the aforementioned relays, transformers, fan operating capacitors, printed boards, or lamp houses. Various electrical components (not shown) such as assemblies are stored.

Reference numeral 6 denotes a fan drive motor installed and supported at the lower part of the electrical equipment box 5 by suitable means.

The electrical component box 5 is constructed by fixing two resin cases against each other, and a mounting hole 8 is formed in the approximately horizontal crotch portion 7 as shown in FIGS. 4 to 8. There is.

In the figure, 9, 9 are both side edges 8a of the mounting hole 8.
, 8a (see FIGS. 1 and 8) to the raised side wall 10, and a guide groove 11. is provided on the opposite surface thereof. ．．
11 is a guide rail formed, 12 is this guide groove 11
．． 11 is a rectangular sheet metal plate of a predetermined size that can be slidably inserted into the plate.As shown in FIG. For example, forming a fitting hole 14 having a rectangular shape and having locking notches 13, 13 at symmetrical positions on both sides,
Protrusions 16.16 are provided on both sides of the outer edges of the guide rails 9, 9 to abut against the edge surfaces 15.15 of the guide rails 9, 9, and furthermore, protrusions 16.16 are provided at predetermined positions on the back surface 12a to engage with the edge 8b of the mounting hole 8. A locking protrusion 17 is provided.

Reference numeral 18 is a resin connector on the electrical component box side, and reference numeral 19 is a lead wire. A locking pawl 18 is provided corresponding to the notch portions 13, 13.
b.

18b is provided.

The locking claws 18b, 18b each have a locking groove 20.20 on the upper side and a locking protrusion 22.22 having a tapered surface 21.21 on the lower end. are doing.

Reference numeral 23 denotes a connector on the fan drive motor 6 side that is connected to the connector 18, and the upper end portion of this connector 23 has locking claws 18b, 18b formed on the connector 18.
A locking portion 24,2 that fits and locks into a locking protrusion 22,22 of
4 is formed.

When attaching and fixing the connector 18 to the electrical component box 5, first insert the plate 12 into the guide grooves 11, 11 formed in the crotch portion 7 of the electrical component box 5, so that the end surface 12 of the plate 12 is
Insert until b contacts the side wall 10.

Then, the protrusions 16.16 come into contact with the end surfaces 15.15 of the guide rails 9, 9, and at the same time the locking protrusion 17 on the back surface 12a locks on the edge 8b of the mounting hole 8, and the plate 12 It is locked and fixed to the above-mentioned attachment hole forming part.

After that, connect the electrical component side connector 18 to the plate 1.
2 into the fitting hole 14.

Then, the locking claws 18b, 1 on both sides of the connector body 18b
8b fits into the locking notches 13, 13 of the fitting hole 14, and its elastic force causes the locking groove 20.20 to fit into the outer edge 13', 13' of the notch 13.13. The connector 18 is fitted into the plate 12, thereby locking and fixing the connector 18 to the plate 12.

When the connector 18 is fixed to the plate 12 in this way, the locking portions 24 and 24 of the connector 23 on the side of the fan drive motor 6 are connected to the locking claws 1 provided on the connector 18.
8b and 18b are fitted and locked to the locking protrusions 22.22 using their tapered surfaces 21.21 and elastic force,
Connect connectors 18 and 23.

In the above embodiment, the fitting hole 14 of the plate 12 is rectangular, but the present invention is not limited to this, and may be formed depending on the shape or size of the connector on the electrical component side.
The shape or size of the fitting hole in the plate 12 may also be changed as appropriate.

As explained above, the present invention forms the mounting hole 8 in a predetermined portion of the electrical component box, and also forms the mounting hole 8 at both side edges 8a of the mounting hole 8.
, 8a are provided, and a plate 12 having a fitting hole 14 of a predetermined shape into which a connector 18 can be fitted and locked is slidably inserted into the guide grooves 11, 11. By fitting and locking the connector 18 into the fitting hole 14, the connector 18 is locked and fixed to the area where the mounting hole 8 is formed, so the connector on the electrical component box 5 side is inserted into the fitting hole 14 of the plate 12. By simply pushing in the connector 18, the connector 18 can be simply and easily fixed to the electrical component box 5.

Therefore, there is no possibility that the connector and lead wire collide with or come into contact with the fan drive motor 6 as in the conventional case.

In addition, by preparing a variety of plates 12 having fitting holes 14 according to the shape or size of the connector 18, various connectors can be easily attached and fixed to the electrical component box by simply replacing the plate 12. The practical effects are extremely large.
