Abstract

PROBLEM TO BE SOLVED: To restrict an increase in a managing labor for parts and contrive the rationalizing of design by a method wherein an earth plate is provided with projections for stopping the rotation of a pull-out terminals of an earth wire in the direction and the orthogonal direction of the lengthwise direction of the same. SOLUTION: An earth screw 4 is attached to one surface of an earth plate 1. A projection 1a for stopping the rotation in the lengthwise direction of the earth plate 1 and another projection 1b for stopping the rotation in the orthogonal direction of lengthwise direction of the earth plate 1 are provided on the other surface of the earth plate 1 as the stopper of the rotation of an earth pull-out terminal 2a. The earth lead wire 2 is pulled out into the lengthwise direction and an earth lead terminals 2a is fixed by a pull-out wire fixing screw 3. In another way, the earth lead wire 2 is pulled out into the orthogonal direction of the lengthwise direction of the earth plate and the earth lead terminal 2a is fixed by the earth lead wire fixing screw 3. According to this method, the earth pull-out wire 2 is permitted so as to be turned to either direction of the lengthwise direction and a direction orthogonal to the lengthwise direction of the earth plate 1 whereby the same earth plate 1 can be used regardless to the change of the internal structure of a main body and the increase of a managing labor for parts can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grounding device for an indoor unit of a separate type air conditioner.

[0002]

2. Description of the Related Art A conventional grounding device is shown in FIGS.
As shown in FIG. 2, a ground screw 4 is attached to one surface of the ground plate 1, and a detent protrusion 1a of a ground lead terminal 2a is provided on the other surface in a straight direction with respect to the longitudinal direction of the ground plate 1, and the ground lead wire 2 is formed. It was fixed with the lead wire fixing screw 3.

[0003] As shown in FIG.
The main body fixing screw 5 is fixed to the ground plate attaching portion 6a of the underframe 6 of the air conditioner main body 7, and the ground lead 2 is routed inside the air conditioner main body 7 to connect the other end of the ground lead 2 to the ground. , And is fixed to a metal part formed in the air conditioner body 7.

[0004]

However, in the above-mentioned conventional configuration, the direction in which the ground lead wire 2 is drawn is only a straight direction with respect to the longitudinal direction of the ground plate 1, so that the internal structure of the air conditioner main body 7 is reduced. If it changes, it is necessary to draw the ground lead wire 2 in a direction perpendicular to the longitudinal direction of the ground plate 1 as a configuration of the drawing of the ground lead wire 2. An earthing device that can be pulled out at right angles to the longitudinal direction was used.

[0005] As a result, it is necessary to use two types of grounding devices properly, resulting in an increase in man-hours for parts management and a reduction in design rationalization.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a grounding device in which the types of grounding plates are unified.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is such that a ground lead wire of a ground plate can be drawn in either a straight direction or a right angle direction.

With the above configuration, it is possible to suppress an increase in the number of man-hours for managing the parts and to streamline the design.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the first aspect of the present invention, a rotation preventing projection of a ground lead terminal is provided on a ground plate in a direction perpendicular to a longitudinal direction of the ground plate. With this configuration, the ground lead can be routed in both the straight direction and the right angle direction, and can be used regardless of changes in the internal configuration of the air conditioner body.

According to the second aspect of the present invention, the earth plate is provided with the detent protrusion of the earth lead-out terminal also in the direction perpendicular to the reverse direction, so that the degree of freedom of the wiring is further increased.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) In FIGS. 1 and 2, a ground screw 4 is attached to one surface of a ground plate 1 and a detent for a ground lead terminal 2a is provided on the other surface. Is provided with the rotation prevention protrusion 1a and the rotation prevention protrusion 1b in the direction perpendicular to the ground, so that the ground lead wire 2 is drawn straight out and the ground lead terminal 2a is fixed with the lead wire fixing screw 3, or the ground lead wire 2 is connected in the right angle direction. And the ground lead terminal 2a can be fixed by the lead wire fixing screw 3.

FIG. 4 is a view showing a state in which the ground mounting device of the present embodiment is mounted on the ground plate mounting portion 6a of the underframe 6 of the air conditioner main body 7, and is fixed by the main body fixing screw 5. The ground lead 2 is routed inside the air conditioner main body 7, and the other end of the ground lead is fixed to a metal part formed in the air conditioner main body 7.

In this embodiment, the grounding device is mounted horizontally. However, even if the internal configuration of the air conditioner main body 7 changes and it becomes necessary to make the grounding device vertical. The same ground plate 1 can be used by changing the drawing direction of the ground lead wire 2.

(Embodiment 2) FIGS. 5 and 6 show that the earth plate 1 is provided with a detent 1c in the direction perpendicular to the longitudinal direction of the earth plate 1 as a detent for the earth lead-out terminal 2a. Therefore, the ground lead wire 2 can be pulled out in the direction perpendicular to the reverse direction, and the ground lead terminal 2a can be fixed with the lead wire fixing screw 3.

According to this embodiment, it is possible to draw out in three directions, so that the degree of freedom of routing can be further increased in response to a change in the internal configuration of the air conditioner main body 7.

[0017]

As is apparent from the above embodiment, in the first aspect of the present invention, the rotation preventing projection of the ground lead-out terminal is provided on the ground plate in a direction perpendicular to the longitudinal direction of the ground plate. According to this configuration, the same ground plate can be used even when the direction of the ground lead wire is desired to be changed, so that it is possible to prevent an increase in man-hours for parts management and to further contribute to the design rationalization specification. Can be.
