JPH10284863A - Fixing structure of fan for electronic apparatus - Google Patents

Abstract

PROBLEM TO BE SOLVED: To shorten the time required for fixing and removing while decreasing the number of parts by setting the dimensions of the fitting rib of a lower housing molding substantially equal to the outer dimensions of a fan and providing a housing, i.e., a plastic part, with a fitting rib. SOLUTION: Upper and lower housings 6, 1 constitute the supporting part of a fan wherein the lower housing 1 is integrally molded of plastic and provided with a rib 2. Dimensions at the bottom of the rib 2 are set substantially equal to the outer dimensions of a fan 4 so that the fan 4 can be pushed smoothly into the rib 2 without rattling. Inner dimensions of a rib 7 provided for the upper housing 6 have a margin with respect to the outer dimension of the fan 4 which is thereby built in easily. After the fan 4 is built in the rib 2 of the lower housing 1, the upper housing 6 having the rib 7 is applied from above. According to the structure, the fan 4 can be fixing without requiring any screw.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device requiring an exhaust or intake fan.

In particular, the present invention relates to an electronic device that requires a forced exhaust or intake fan, and does not use screws for mounting the fan. Usually, the fan is installed on the side or the back of the electronic device, and the mounting method is generally to mount the bracket directly to the housing via screws, or to the fan mounting bracket once, and then attach the bracket to the housing. It is a target.

[0003] The present invention relates to an electronic apparatus characterized in that each divided housing is provided with a support shape corresponding to the shape of a fan, and can be mounted without using screws simply by inserting a fan. is there.

[0004]

2. Description of the Related Art As a conventional fan mounting method, a part or the whole of a housing is raised, a tap is cut, and two opposite sides or four squares are fixed with screws, or holes are formed in the raised housing. It was opened and fixed with screws and nuts. As a further alternative, the fan mounting bracket is a separate part from the housing, the fan is mounted on the fan mounting bracket by the above two methods, and the mounting bracket is mounted on the housing with screws or spot welding. The fan was mounted on the bracket for fan mounting integrated with the housing by the above two methods.

[0005]

The above-mentioned prior art includes the following:
Since screws are used, it takes time to mount and remove.
Further, when the fan is removed, the screws may be lost, and there is a disadvantage that the re-attachment may be incomplete. or,
Screw heads can also appear on the surface, which can be a design flaw.

Another object of the present invention is to solve these problems, and a second object of the present invention is to reduce the number of parts for assembly. A third object of the present invention is that the screws are not used, so that the screws do not appear on the appearance, so that the design is refreshing.

[0007]

According to the present invention, in order to achieve the above-mentioned object, a rib for fitting into a plastic part serving as a housing of an electronic apparatus is provided according to the size of a fan to be used. At this time, the ribs for inserting the mold of the lower housing should be fixed to the same dimensions as the outer dimensions of the fan for assembly, and the ribs for inserting the mold of the upper housing should have dimensions so that they can be easily assembled. Make it larger than the fan size.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 is a left side sectional view of a fan mounting portion, FIG. 2 is a front sectional view of the fan mounting portion, and FIG. 3 is an assembled perspective view. 1 is a part of the plastic of the lower housing, 2 is a rib provided according to the outer dimensions of the fan, 3 is
Relief of rib for passing fan cable, 4 is fan, 5 is fan cable, 6 is a part of plastic of upper housing, and 7 is the outer dimension of fan provided in upper housing. It is a rib with a margin.

Hereinafter, the mounting structure and mounting method of the fan will be described. The lower housing 1 and the ribs 2 are a one-piece molded product of plastic and have a draft.
The minimum bottom dimension of the inner size of the rib 2 is almost the same as the outer dimension of the fan 4. The fan 4 has a structure that can be pushed into the rib 2 without difficulty and without rattling. ing. Next, the inner dimensions of the upper housing 6 and the ribs 7 provided on the 6 are provided with a margin with respect to the outer dimensions of the fan 4 so that they can be easily incorporated.

Accordingly, the structure is such that the upper housing 6 having the ribs 7 can be easily assembled from above after assembling 1-4.

[0011]

As an effect of the present invention, since the fan is not mounted with screws, a mounting bracket for the fan is unnecessary, and a boss for mounting the mounting bracket to the lower housing or the upper housing is provided. The unnecessary economic effect is considered.

Furthermore, since the screw head is not mounted, the head of the screw does not appear on the surface, which has a design effect.
