Description
Technical field
The utility model is the connected structure about a kind of sheet metal, particularly about a kind of connected structure that is applied in the sheet metal that splices.
Background technique
Electronic technology is maked rapid progress at present, various for example is that other electronic equipments such as computer, server are sold on market like the mushrooms after rain, the structural design that adds electronic equipment is more and more accurate with in response to multi-functional demand, therefore how effectively carrying out the electronic equipment inner space utilizes, to realize maximization of economic benefit, become the problem of present industry institute concern, the engagement function on the also therefore various electronic equipment seems and becomes more and more important.
In the prior art, as being the electronic equipment of example with the server, its is in order between the sheet metal that constitutes casing, mainly is the joint perforate that utilizes the conjugative component of rivet for example to wear empty this sheet metal, carries out the purpose of riveting job to realize being bonded with each other.See also Figure 1A and Figure 1B, it is solid and the generalized section that is used in the prior art after the sheet metal mutual superposition of casing of electronic apparatus at its junction point.As shown in the figure, in the casing design of electronic equipment, be that two sheet metals 10 are superimposed with each other, and its joint perforate 1 that is provided with out of the ordinary is aimed at mutually, engage operation for conjugative components such as for example rivets.Wherein, this sheet metal 10 is the designs of the straight plate structure of plane type, and the joint perforate 1 of adopting bore mode for example to form on this sheet metal 10 also is the through hole shape structure of plane type.
Though this joint open-celled structure has advantage easy to process, along with more and more higher to the requirement of electronic equipment reliability now, the shortcoming of its existence also shows.Because these two sheet metals only are to have the face contact on the Vertical direction surperficial with respect to it, with tensile stress and the stress of guaranteeing that it can bear bigger Vertical direction.Yet, in the horizontal direction relatively, then mainly be that point by riveted joint place contacts and guarantees its intensity, this point contact junction structure can't bear the stress of bigger parallel direction obviously, if when electronic equipment produced bigger shake in parallel direction, often this conjugative component can't bear the mutual stress of two sheet metals, make this bonding point loosening, more seriously, even can produce the situation that this conjugative component is twisted off by force.
In addition, this kind plane type engages open-celled structure, for the electrical assembly in the casing of electronic apparatus that is built in this sheet metal formation, and can't provide effect ELECTROMAGNETIC OBSCURANT effect, this is because during the joint of this sheet metal, the joint clearance of sheet metal is the straight line form each other, the electromagnetic wave that produces when causing the electronic equipment operation is easy to outside rectilinear clearance is radiated casing, cause electromagnetic radiation leakage, simultaneously, relatively also cause external electromagnetism spoke to invade in the casing easily, influence the performance and the reliability of electronic equipment.
Therefore, develop a kind of connected structure that can strengthen tensile stress, pressure stress and the shear strength of the junction point of sheet metal simultaneously, and preferable ELECTROMAGNETIC OBSCURANT effect is provided, real problem for demanding urgently at present inquiring into.
The model utility content
For overcoming the shortcoming of above-mentioned prior art, main purpose of the present utility model is to provide a kind of connected structure of sheet metal, can strengthen casing of electronic apparatus structural strength and rigidity.
Another purpose of the present utility model is to provide a kind of connected structure that enlarges the sheet metal of bonding area.
A purpose more of the present utility model is to provide a kind of connected structure that improves the sheet metal of shear strength.
Another purpose of the present utility model is to provide a kind of connected structure of sheet metal, can improve the ELECTROMAGNETIC OBSCURANT effect of electronic equipment.
For reaching above-mentioned and other relevant purpose, the utility model provides a kind of connected structure of sheet metal, with riveted joint mode many strip metals plate that splices, the connected structure of sheet metal comprises: correspondence respectively this sheet metal is formed with corresponding evagination perforate at the riveted joint junction point, the evagination perforate of one sheet metal is engaged in the evagination perforate of another sheet metal, increase the area of contact of junction point between the sheet metal, improve its structural strength, strengthen ELECTROMAGNETIC OBSCURANT (EMC) effect of the junction point of this sheet metal simultaneously.
The evagination perforate of the junction point of this sheet metal is convexly equipped with and is formed by the sheet metal extension, and is in Different Plane with this sheet metal body.This bonding point is to be the round platform form, coincides mutually for the sheet metal that will engage, and makes wherein that a sheet metal evagination perforate is placed in another sheet metal evagination perforate.This bonding point also can be to be the sleeve form, and wherein a sheet metal evagination perforate is ccontaining and exposes in another sheet metal evagination perforate.
Compared with prior art, the connected structure of sheet metal of the present utility model, be that plane type when existing sheet metal riveted joint is engaged engages open-celled structure and improves, provide a kind of outer convex type to engage open-celled structure, increase the area of contact between the sheet metal that will engage, and then increase the shearing stress of junction point and improve its structural strength, solved the not good disappearance of structural strength that prior art causes because of area of contact is less.
In addition, because being used to rivet the perforate of junction point in the connected structure of sheet metal of the present utility model is the evagination form, therefore being in contact with one another face with respect to this sheet metal is to present bended, so, having overcome existing sheet metal riveted joint junction point adopts plane type to engage electromagnetic radiation that perforate the causes straight line situation of passing through easily, the utility model can reduce passing through of electromagnetic radiation effectively, provides electronic equipment good electromagnetism screening effect.
