Abstract

PROBLEM TO BE SOLVED: To mount a blower without being obstructed by a lead wire and increase the strength of a frame and an insertion port by forming a hold groove which supports the lead wire integrally in such a way that it is continuous between respective peripheral fringe parts of end plates. SOLUTION: A hold groove 21 and an insertion port 22 are integrally provided between end plates. A lead wire passes a guide groove 16 of the end plate, is inserted through an insertion port 197 and passes through a hold groove 18. Then, it passes the insertion port 22, the hold groove 21, an insertion port 19A, and a hold groove 18A in this order and is pulled out to the outside of the other end plate. A blower can be mounted without being obstructed by the lead wire by pulling out the lead wire in this way. Furthermore, since the hold groove 21 and the insertion port 22 are integrally provided between the end plates, it is possible to increase the strength of the insertion ports 19, 19A.

Description

The present invention relates to a lead wire holding structure for an axial blower.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional lead wire holding structure of an axial blower. The structure of FIG. 6 will be described. Reference numeral 61 denotes a frame, which is an end plate facing each other.
3 and a cylindrical tube portion connected to it. 64
Is an electric motor portion housed in the above-mentioned tubular portion, and 65 is an electric motor portion 64
The blade 66 attached to the end plate 62 is a guide groove for guiding a lead wire 67 provided on the front surface of the end plate 62, and the holding member 68 is connected to the guide groove 66 so as to penetrate the peripheral edge of the end plate 62 in the thickness direction. The groove 69 is continuously connected to the holding groove 68 and the end plate 62.
The insertion opening has a width through which one lead wire 67 passes. The one end plate 63 also has a holding groove 68A and an insertion port 69A as in the case of the end plate 62.

The conventional method of holding the lead wire of an axial blower is constructed as described above, and the lead wire of the motor 64 is connected to the end plate 6.
2 is passed through the guide groove 66 and inserted one by one into the holding groove 68 from the insertion opening 69 of the holding portion.
2 and 63 or through 62 and 63 to the outside of the end plate 63.

[0004]

Since the end plates 62 and 63 stand independently of the cylindrical portion, cracks and cracks are caused by external stress (for example, pulling while the lead wire is hooked).

[0005] Only the lead wire can be held after passing through the end plate 62 or 62, 63, and the lead wire cannot be held just before the end plate 63.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to easily install a blower to increase the strength of an end plate in holding and fixing a lead wire, and to hold a lead wire. It is an object of the present invention to provide an axial blower that can easily be fixed.

According to a first aspect of the present invention, there is provided a frame for supporting a motor unit for driving a blade between end plates facing each other, a lead wire connected to the motor unit, and the end unit. And a holding groove for supporting the lead wire, which is formed integrally so as to be continuous between the respective peripheral portions of the plate.

According to a second aspect of the present invention, each end of the end plate has an insertion portion having an opening communicating with the holding groove, and the insertion portion has an opening width of one lead wire. The holding groove is formed so that a plurality of the lead wires can be arranged in the holding groove.

According to a third aspect of the present invention, there is provided a frame for supporting a motor portion for driving a blade between end plates facing each other, a lead wire connected to the motor portion, and a peripheral portion of each of the end plates. A holding groove for supporting the lead wire integrally formed so as to be continuous with each other, and an insertion portion comprising a peripheral portion of each of the end plates and an opening between the peripheral portion and the opening communicating with the holding groove; The opening width of the portion is formed so as to accommodate one lead wire, and the inside of the holding groove is formed so that a plurality of the lead wires can be provided.

Is a lead wire guide groove of the end plate 12, 17 is a lead wire for energizing the motor, 18, 18A and 21 are holding grooves, 19, 19A and 2
2 is an insertion port.

In the axial blower constructed as described above, the lead wire 17 passes through the guide groove 16 of the end plate 12 and the insertion port 19.
Through the holding groove of 18 and 21 through the insertion opening of 22
Is drawn out of the end plate 13 through the holding groove of 18A, through the insertion slot of 19A, through the insertion slot of 19A. The lead wire 17 thus drawn out is attached to the set side without being disturbed by the end plate 13, and a holding groove 21 and an insertion opening 22 are integrally provided between the end plates 12 and 13. Therefore, the strength of the insertion port of 19, 19A can be increased.
