Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a structure for holding a lead wire of an axial blower.

[0002]

[Prior art]

 A conventional wire holding structure for an axial blower is shown in FIG. The structure of FIG. 6 will be described. Reference numeral 61 denotes a frame which is composed of end plates 62 and 63 facing each other and a cylindrical tube portion connected to the end plates 62 and 63. Reference numeral 64 is an electric motor portion housed in the cylindrical portion, 65 is a blade attached to the electric motor portion 64, 66 is a guide groove for guiding a lead wire 67 provided on the front surface of the end plate 62, and 68 is a guide groove 66. A holding groove that continuously penetrates the peripheral edge portion of the connecting end plate 62 in the thickness direction, and 69 is continuously connected to the holding groove 68 and opens at the peripheral edge portion of the end plate 62 to pass one lead wire 67. It is an insertion opening with a width. Further, one of the end plates 63 also has a holding groove 68A and an insertion opening 69A like the end plate 62.

The conventional method of holding the lead wire of the axial blower is configured as described above. The lead wire of the electric motor 64 is drawn out of the end plate 62, passes through the guide groove 66, and is inserted from the insertion port 69 of the holding portion 1 to 1. After they are inserted into the holding groove 68 one by one, they are pulled out to the outside of the end plate 63 between the end plates 62 and 63 or through the end plates 62 and 63.

[0004]

[Problems to be solved by the device]

 Since the end plates 62 and 63 stand independently of the tubular portion, external stress (for example, pulling with the lead wire hooked) causes cracks or cracks. Only the lead wire could be held after passing through the end plate 62 or 62, 63, and the lead wire could not be held before the end plate 63.

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

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a guide groove for the lead wire, a holding groove, and an insertion port in the end plate portion of the frame from which the lead wire for energizing the motor is drawn out, and also holds it in one end plate portion. A groove and an insertion port are provided to facilitate the installation of the blower, and the end plates are connected to each other as a guide groove and an insertion port for passing a lead wire, and the gap is set so that one lead wire can be inserted. Is characterized by being able to be held by holding grooves at different positions.

【Example】

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

FIG. 1 and FIG. 2 are a perspective view showing a first embodiment of the present invention and an enlarged perspective view of an essential part. In the figure, 11 is a frame, 12 and 13 are end plates, 14 is an electric motor part, 15 is a blade, 16 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, Reference numerals 19, 19A and 22 are insertion openings.

In the axial blower configured as described above, the lead wire 17 passes through the guide groove 16 of the end plate 12, passes through the insertion slot 19 and passes through the holding groove of 18, and passes through the insertion slot of 22 and is retained by 21. It is drawn out of the end plate 13 through the holding groove, the insertion opening of 19A and the holding groove of 18A. 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 port 22 are integrally provided between the end plates 12 and 13. Therefore, the strength of the insertion port of 19, 19A can be increased.

FIG. 3 and FIG. 4 are perspective views showing a second embodiment of the present invention and an enlarged perspective view of a main part. In the drawing, 31 is a frame, 32 and 33 are end plates, 34 is an electric motor part, 35 is a blade, 36 is a lead wire guide groove for the end plate 32, 37 is a lead wire for energizing the motor, 38, 38A and 42 are holding grooves, Reference numerals 39, 39A and 41 are insertion openings.

In the axial blower configured as described above, the lead wire 37 passes through the guide groove 36 of the end plate 32, passes through the insertion groove 39, passes through the holding groove of 38, and one lead wire 37 passes through. It passes through the set insertion opening of 41, passes through the holding groove of 42, enters from the insertion opening of 39A, and is drawn out of the end plate 33 through the holding groove of 38A. The lead wire 37 thus drawn out is attached to the set side without being disturbed by the end plate 33, and a holding groove for 41 and an insertion port for 42 are integrally provided between the end plates 32 and 33. Therefore, the strength of the 39, 39A insertion port can be increased.

FIG. 5 is a perspective view showing a third embodiment of the present invention.

In the axial blower configured as described above, the lead wire 37 is drawn out from between the end plate 32 and the insertion port 42 and between the insertion port 42 and the insertion port 39A provided in the end plate 33 and attached to the set. Is also possible. (FIG. 5 shows a state in which the lead wire is pulled out from between the insertion opening 42 and the insertion opening 39A provided in the end plate 33.)

[0014]

[Effect of device]

 As described above, the present invention has the following great advantages.

According to the first embodiment of the present invention, each end plate of the frame is provided with a holding groove for the lead wire, and the end plate portions are connected as guide grooves for passing the lead wire. This makes it easy to attach the blower without hindering the lead wires when fixing the blower to the set, and also increases the strength of the frame and insertion slot. According to the second and third embodiments of the present invention, the guide groove for passing the lead wire provided between the end plate portions is set to a gap such that one lead wire is inserted, and the lead wires are at different positions. It can be held by the holding groove of the fan, and by connecting it as a guide groove for passing the lead wire between each end plate part, you can easily install the blower without disturbing the lead wire when fixing the blower to the set. At the same time, the strength of the frame and holding groove is also increased.
