Description

[Detailed Description of the Invention] The present invention relates to a shroud for guiding fan wind of a radiator fan.

Conventionally, as shown in FIG. 1, this type of shroud has one resin shroud frame 2a having a semicircular opening 1a and the other resin shroud frame 2b having a semicircular opening 1b. Abutting plates 3a, 3 of both resin shroud frames 2a, 2b
Clip mounting grooves 4a and 4b having a U-shaped cross section as shown in FIG. 2 are formed in b, and both clip mounting grooves 4
It has a structure in which both resin shroud frames 2a and 2b are fixed by extending an arcuate clip 5 between a and 4b.

However, since the clip mounting grooves 4a and 4b formed in the abutment plates 3a and 3b are provided in a direction different from the mold removal direction, it is naturally impossible to form deep grooves, and it is not possible to form a certain precise groove. is difficult to form, and therefore the clip 5 is not attached sufficiently.
It was not possible to obtain a strong fixation, and the attached clip 5 often came off, resulting in a lack of reliability.

The present invention was made to eliminate such drawbacks, and has a structure in which both resin shroud frames are firmly fixed.
Moreover, it is an object of the present invention to provide a highly reliable shroud in which the fixing clips will not come off.

The shroud according to the present invention includes one resin shroud frame having a roughly semicircular opening;
In a shroud in which both resin shroud frames are fixed to each other by abutting against the other resin shroud frame having a semicircular opening and an arcuate clip is interposed between the two abutting plates, each of the two abutting plates is A stepped portion is provided, a clip mounting hole is provided passing through the stepped portion, and both resin shroud frames are fixed by fixing the clip between the contact plates having the clip mounting hole, as shown in the drawings below. This will be explained in more detail below.

FIG. 3 shows an embodiment of the shroud of the present invention.

One of the resin shroud frames 6a has a semicircular opening 7a at the top and a frame body having an abutment plate 8a at the lower end, and the other resin shroud frame 6b
consists of a frame body having a lower semicircular opening 7a and an abutment plate 8b at the upper end. Both resin shroud frames 6a, 6b are in contact with each other at contact plates 8a, 8b, and are fixed via arcuate clips 9.

As shown in FIG. 4, each of the contact plates 8a and 8b is a plate having a stepped portion 10 on the tip side, and each stepped portion 10 has a clip attachment hole 11 penetrating from the outside to the inside. As shown in FIG. 5, the hole 11 is a mounting hole whose lower side has a width equal to or slightly wider than the plate width of the arcuate clip 9, that is, a width l. Then, as shown in FIG.
a, 9b are respectively fitted into the respective clip mounting holes 11 of the respective contact plates 8a, 8b, and the clips 9 are attached, thereby fixing both the resin shroud frames 6a, 6b.

The shroud according to the present invention has such a structure, and the step portions 10 are provided on both the resin shroud frames 8a and 8b, and the clip attachment holes 11 are provided therethrough, so that the shroud can be easily removed in the resin mold removal direction. A penetrating clip attachment hole 11 can be formed,
Naturally, accurate through holes are provided. Therefore, the end windings 9a and 9b of the clip 9 are deeply inserted into the corresponding clip attachment holes 11, and the clip 9 can be securely attached, and the resin shroud frames 8a and 8b are firmly fixed by the clip 9. can. Moreover,
Since the hole width l on the lower side of each clip attachment hole 11 is the same as or slightly wider than the plate width of the arc-shaped clip 9, the clip 9 can be easily positioned.
Can be installed accurately.

Furthermore, since the end winding portions 9a and 9b of each clip 9 are deeply fitted into the corresponding clip attachment holes 11, the clips 9 do not come off.

In the above embodiment, the resin shroud frame 6
Clip 9 with a and 6b attached to the left and right respectively
However, if the resin shroud frame is large, the width of the clip attachment holes provided on both abutting plates should be set to the width of two clips arranged in parallel, and both resin shroud frames should be fixed in place. It can be securely fixed by fixing it with two clips. In this way, when fixing with two or more clips, even stronger fixation can be obtained. The present invention is of course applicable not only to the case where two upper and lower resin shroud frames are fixed via clips, but also to the case where left and right resin shroud frames are fixed via clips.

As described above, according to the present invention, the abutment plates of both resin shroud frames are each provided with a stepped portion, and the clip mounting holes are provided in the stepped portions, so that the clip mounting holes can be accurately aligned in the mold removal direction. This allows both ends of the clip to be inserted deeply,
Not only can the resin shroud frame be firmly fixed, but the clips once installed will not come off, and a highly reliable shroud can be obtained.
