Japanese Patent Application No. Hei.
No. 6-262303, rivet abutment
Strengthen the two members to be joined together using the binding member and the adhesive
A rivet combined bonding method for firmly joining has been proposed.
This rivet combination bonding method is shown in FIGS.
When applied to an electronic device housing, for example, FIG.
The outer surface of the rising portion 17 of the bottom plate 2 and the inner surface of the side plate 3
The outer surface of the bent portion 23 is bonded with an adhesive layer.
And joined by fastening with rivets or other fastening members.
In the same way for the other parts, the panel is
They are joined together to form a housing. This rivet
The housing assembled by the combined bonding method is
It is not necessary to withhold the next process until the
Uses tools that do not require skill for rivet and gun operation
The work process is simple because it only needs to be
Correction work is not required because there is no deformation.
The method of bonding together is an excellent technique. [0008] [Problems to be solved by the invention] January 17, 1995
Due to the Kobe Nanbu earthquake, structural resistance in various fields
Re-evaluation of seismicity became necessary. Electronics related to this invention
Also assembled by welding in the field of equipment housing
There have been reports of cracks in the control panel welds.
You. For electronic equipment housing by the above-mentioned rivet combined bonding method
Regarding this, the evaluation of the seismic resistance schematically shown in FIG. 36 was performed. Immediately

The mounted internal mounting units etc. are greatly deformed respectively
To be destroyed or fall off from the fixture
Become. It is also located adjacent to other equipment and structures.
Control panel will be driven into it.
The damage is great. In the example of a control panel with a height of 2300 mm
The amplitude of the vibration applied to the base was 10 mm
And the amplitude at the top of the control panel is about 300 mm, about 30 times
And the response rate (ie, upper amplitude (y) / base amplitude)
The width (x) was about 30. Accordingly, an object of the present invention is to fasten a rivet or the like.
Assembled with the adhesive used together with the knot, the required resistance
Provide an electronic device housing with sufficient rigidity to obtain seismic properties
Is Rukoto. [0010] In order to achieve the above object,
