Abstract

PURPOSE: To effectively and rigidly fix a power cord to an electric equipment by forming a through hole to be inserted with a screw at a clamper for holding the cord and a power cord-fixing unit, and forming a threaded hole for a screw to be engaged with the fixing site. CONSTITUTION: The inside dimension between opposed surfaces 11 and 12 of a clamper fixing plate 10 is set at most the same as the thickness of a flange 2. When the flange 2 is inserted to the opening, the plate 10 is held by the flange 2 by the elasticity between the surfaces 11 and 13. A clamper 4 for sandwiching a power cord 3 between an upper plate 5 and a lower plate 6 is brought into contact with the plate 10, and a screw 7 is inserted in and clamped at the communicating through holes 8, 9, 12, 15 and threaded hole 14. Thus, the cord 3 hold by the clamper 4 is effectively and rigidly fixed to the flange 2, and the connector of the cord 3 is not disconnected due to the application of an external force to the connector of the cord 3.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power cord fixing device for fixing a power cord of an electric device to a device body and a refrigerator provided with the power cord fixing device.

[0002]

2. Description of the Related Art In a conventional refrigerator, a power cord is fixed to a refrigerator body as disclosed in, for example, Japanese Utility Model Publication No. 54-38624, which will be described below with reference to FIGS. 8 and 9. .

A compressor 52, a condenser 53 and the like, which constitute a cooling device, are arranged on the back surface of the refrigerator main body 51, and power is supplied by a power cord 54 (see FIG. 8). The power cord 54 has a clamper 55 attached to the power cord 54, which is fixed to the flange portion 57 of the outer box 56 of the refrigerator body 51 with screws 58 in order to maintain the strength of the connection portion. 51
It was fixed to the outer box 56 (see FIG. 9).

[0004]

In the conventional fixing of the power cord, in order to securely and firmly fix the power cord 54 to the outer box 56, the clamper 55 is screwed by the screw 58 to the outer box 56.
However, it is difficult to form a thread on which the screw 58 is firmly screwed, and as a result, the power cord is There is a problem that the connecting portion is easily broken by an external force.

In order to solve this problem, a plate-shaped component is attached to the portion of the outer box 56 where the clamper 55 is fixed by welding, rivets, etc., and the screw is secured by this plate-shaped component. However, there is a problem in that a work such as welding, rivets and the like is difficult to attach to a place such as a back surface of a refrigerator, a work time is significantly increased, and a component cost is also increased.

It is an object of the present invention to provide a power cord fixing device capable of fixing a power cord to an electric device securely, firmly and with good workability, and also to securely and firmly fix the power cord. The purpose of the present invention is to provide a refrigerator that has no fear of disconnection at the connection part.

[0007]

In order to achieve the above object, in the power cord fixing device of the present invention, the clamper holding the power cord and the power cord fixing portion with which the clamper abuts has a penetrating hole for inserting a screw. A hole is formed, and a screw hole into which the screw is screwed is formed in a fixing portion that abuts the power cord fixing portion.

Further, a screw is attached to the power cord fixing portion, the fixing plate having a U-shaped cross section fitted in the power cord fixing portion, and the clamper for holding the power cord and abutting on one surface of the fixing plate. A through hole to be inserted is formed, and a screw hole into which the screw is screwed is formed on the other surface of the fixing plate.

Further, a screw is attached to the power cord fixing portion, one surface of the fixing plate fitted in the power cord fixing portion and having a U-shaped cross section, and the clamper which abuts on this one surface and holds the power cord. A through hole to be inserted is formed, and a screw hole into which the screw is screwed is formed on the other surface of the fixing plate.

Further, a through hole for inserting a screw is formed in the power cord fixing portion and the clamper for holding the power cord and abutting on one surface of the power cord fixing portion.
A screw hole into which the screw is screwed is formed in the electrical component storage box that abuts on the other surface of the power cord fixing portion.

In order to achieve the above object, in the refrigerator of the present invention, a flange portion of an outer box, a fixing plate having a U-shaped cross section fitted to the flange portion, and a power cord are held, and the fixing plate is provided. One in which a through hole is formed in the clamper that abuts one surface, a screw hole is formed in the other surface of the fixing plate, and the power cord is fixed to the main body by the through hole and the screw inserted in the screw hole. Is.

Further, a through hole is formed in the flange portion of the outer box, one surface of the fixing plate fitted in the flange portion and having a U-shaped cross section, and the clamper which is in contact with the one surface and holds the power cord. A screw hole is formed on the other surface of the fixing plate, and the power cord is fixed to the main body by a screw inserted into the through hole and the screw hole.

Further, a through hole is formed in the clamper that holds the flange portion of the outer box and the power cord and is in contact with one surface of the flange portion, and the electrical component is in contact with the other surface of the flange portion. A screw hole is formed in the storage box, and the power cord is fixed to the main body by a screw inserted in the through hole and the screw hole.

[0014]

In the power cord fixing device configured as described above, a screw hole into which a screw for fixing the power cord is screwed is formed in a fixing portion which is held only by contacting the power cord fixing portion. Therefore, the screw hole having the screw thread with which the screw is screwed is surely secured, and the power cord is securely fixed.

Further, since the screw hole into which the screw for fixing the power cord is screwed is formed on one surface of the fixing plate having a U-shaped cross section fitted in the power cord fixing portion, the power cord is fixed. A screw hole having a thread with which a screw is screwed is surely secured in the power cord fixing portion, so that the power cord is firmly fixed.

Further, a screw for fixing the power cord to the other surface of the fixing plate is held by the clamper and one surface of the fixing plate having a U-shaped cross section fitted to the power cord fixing portion. Since the screw hole having the screw thread is formed, the screw hole is secured in the power cord fixing portion and the power cord is firmly fixed.

Further, since the screw hole for engaging the screw for fixing the power cord is formed in the electrical equipment storage box which is in contact with one surface of the power cord fixing portion, the screw hole is secured in the power cord fixing portion. The power cord is firmly fixed.

Further, since a screw hole for fixing the power cord is formed on one surface of the fixing plate having a U-shaped cross section fitted to the flange portion of the outer box, the power cord is the refrigerator body. It is firmly fixed to and eliminates disconnection at the connection due to external force.

A screw for holding the power cord by one side of a fixing plate having a U-shaped cross section and a clamper fitted on the flange portion of the outer box, and fixing the power cord on the other side of the fixing plate is provided. Since the screw hole for screwing is formed, the power cord is securely and firmly fixed to the refrigerator main body, and the disconnection due to the external force at the connecting portion hardly occurs.

Further, the electrical equipment storage box is brought into contact with one surface of the flange portion of the outer box, and the electrical equipment storage box is formed with a screw hole into which a screw for fixing the power cord is screwed. The power cord is firmly fixed to the refrigerator body together with the product storage box, so there is no disconnection at the connection part.
