Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing indoor and outdoor connecting electric wires of an indoor unit of a separate room air conditioner.

[0002]

2. Description of the Related Art Conventionally, in this type of fixing structure, as shown in FIG. 3, an internal / external connecting electric wire 6 is connected to a terminal block 7 fixed to an electrical equipment box 10 and electrically connected to an electronic control unit 11. We exchange power and signals between the indoor unit and the outdoor unit,
In order to prevent the inner / outer connection line 6 from being pulled by an external force and exerting a force on the connection portion with the terminal block 7, the inner / outer connection line 6 is fixed to the electrical equipment box 10 in front of the terminal block 7 by the fixture 1. As shown in FIGS. 4 and 5 (FIG. 5 shows a cross-sectional view of the perspective view shown in FIG. 4 viewed from the direction C), the fixing structure connects the inside / outside connecting wire 6 to the terminal block 7. After that, the fixture 1
The concave portion 1 provided with the convex portion 12 provided at the end of the
3, which is inserted as shown in D in FIG. 5, is fixed to a pedestal 4 provided in a part of the electrical equipment box with a screw 5, and the internal / external connection electric wire 6 is sandwiched and fixed between the electrical equipment box and the fixture 1. Is.

[0003]

However, with the above-mentioned conventional fixing structure, the connection of the internal / external connecting electric wire 6 to the terminal block 7 and the fixing by the fixing tool 1 are performed during the installation or service of the air conditioner. Although it is carried out by a trader, since the protrusion 12 of the fixture 1 is simply inserted into the recess 13 of the electrical equipment box, when fixing it to the pedestal 4 with the screw 5,
The fixture 1 often dropped onto the floor.

As a result, particularly when the indoor unit is a wall-mounted type, it is necessary to once go down from a chair or the like to pick up a fixture that has fallen to the floor surface, and there is a lot of wasted time during installation and service, Some improvement was required.

In order to solve the above-mentioned conventional problems, the present invention prevents the fixing tool for the fixing structure of the internal and external connecting electric wires from falling on the floor surface, and eliminates the waste of time at the time of installation and service due to the drop. The purpose is to do.

Another object of the present invention is to facilitate the assembling of the internal / external connection electric wire fixing structure.

A further object of the present invention is to facilitate the fixing of the internal / external connecting electric wires during installation or service.

[0008]

In order to achieve the above object, the present invention provides a fixture with a shaft portion which is fitted into a bearing portion provided in a part of an electrical equipment box.

Further, according to the present invention, the bearing portion of the electrical equipment box is provided with a notch portion having a width dimension smaller than the shaft diameter of the shaft portion of the fixture.

Further, according to the present invention, the bearing portion of the electrical equipment box is provided with a notch portion having a width dimension larger than that of the fixture.

[0011]

The operation of the above means is as follows.

According to the present invention, the fixture is provided with the shaft portion and fitted into the bearing portion of the electrical equipment box, so that the fixture does not drop on the floor surface during installation or service.

Further, according to the present invention, the shaft portion of the fixture can be inserted into the notch provided in the bearing portion, and the fixture and the electrical equipment box can be easily fitted during assembly.

Further, according to the present invention, the notch portion provided in the bearing portion enables rotation up to a large angle, so that the electric wire for connecting inside and outside can be easily fixed at the time of installation or service.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 1 is a perspective view of a structure for fixing the inner and outer connecting wires of one embodiment of the present invention, and FIG. 2 is a sectional view of the perspective view shown in FIG.

In FIG. 1, reference numeral 1 denotes a fixture, which is provided with a shaft portion 2 at an end portion thereof, is fitted into a bearing portion 3 provided at a part of an electrical equipment box, and is configured to be rotatable. Further, the end of the fixture 1 on the side opposite to the shaft portion 2 is screwed to a pedestal 4 provided in a part of the electrical equipment box so as to press down the internal and external connection electric wires 6 connected to the terminal block 7. It is fixed at.

In the above structure, the screws 5 are removed or tightened at the time of installation or service, and the fixtures 1 are
Is removed from the pedestal 4 or fixed, but since the shaft portion 2 of the fixture 1 is fitted with the bearing portion 3 of the electrical equipment box, the fixture 1 does not come off from the electrical equipment box.

Therefore, it is possible to eliminate the waste of time that the fixing tool 1 has to be dropped from the chair or the like and picked up when the fixing tool 1 is dropped on the floor surface or the like.

Further, in the figure, reference numeral 8 denotes a notch portion provided in the bearing portion 3, the clearance dimension thereof is slightly smaller than the shaft diameter of the shaft portion 2 of the fixture 1, and the bearing portion 3 has the notch portion. Part 8
Is made of thick resin that expands slightly when force is applied.

In the above structure, when the shaft portion 2 of the fixture 1 is fitted to the bearing portion 3, the shaft portion 2 can be inserted by applying force from the notch portion 8 and fitted to the bearing portion 3. Since it is possible, it is easy to assemble the electric wire fixing structure for the inside and outside of the air conditioner.

Further, in the figure, a notch 9 having a width dimension larger than the width dimension of the fixture 1 is provided in the central portion of the bearing portion 3.

In the above-mentioned structure, as shown in FIG. 2B, the fixture 1 rotates around the shaft portion 2 in a very wide range of angles up to 90 degrees or more until the end face of the notch 9 is hit. Therefore, the work becomes easy when connecting the internal / external connecting electric wire 6 to the terminal block 7 at the time of installation or service.

[0023]

As is apparent from the above-described embodiments, the present invention provides a separate type air conditioner internal / external connection electric wire fixing structure in which a shaft portion is provided in a fixture and is fitted into a bearing portion provided in a part of an electrical equipment box. As a result, the fixture does not come off the electrical equipment box. As a result, it is possible to eliminate waste of work time during service and installation due to the fixing tool falling onto the floor or the like.

Further, by providing the bearing portion with a cutout portion having a clearance dimension smaller than the shaft diameter of the shaft portion of the fixture, the shaft portion of the fixture is inserted from the cutout portion and the fixture is fitted into the bearing portion. As a result, the work of assembling the fixing structure for the internal and external connecting electric wires of the air conditioner becomes very easy.

Further, by providing the bearing portion with a notch having a width dimension larger than the width dimension of the fixture, the fixture can rotate around the shaft portion about the shaft portion in a very wide range of angles. , The work at the time of installation and service becomes easy.
