Detailed Description
In order to facilitate an understanding of the utility model, the utility model is described in more detail below with reference to the accompanying drawings and specific examples. It is noted that when an element is referred to as being "secured to"/"mounted to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. As used in this specification, the terms "upper," "lower," "inner," "outer," "vertical," "horizontal," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the utility model and simplicity in description, and do not indicate or imply that the referenced devices or elements must be in a particular orientation, constructed and operated in a particular orientation, and are not to be considered limiting of the utility model. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Furthermore, the technical features mentioned in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, the sheet metal spliced type chassis includes a first sheet metal 10 and a second sheet metal 20, and the second sheet metal 20 is fixed on a surface of the first sheet metal 10.
As shown in fig. 2, a plurality of first contact points 11 are uniformly distributed on the edge of the first metal sheet 10.
In order to ensure a better electrical connection when the first metal sheet 10 is in contact with the second metal sheet 20, the distance between two adjacent first contact points 11 should not be too large or too small, and is preferably 2 cm.
Correspondingly, a plurality of second contact points 21 matched with the first contact points 11 are uniformly distributed on the edge of the second metal sheet 20.
The interval between two adjacent second contact points 21 is the same as the interval between two adjacent first contact points 11, so as to ensure that the first metal sheet 10 and the second metal sheet 20 are electrically connected through the mutual contact of the first contact points 11 and the second contact points 21.
By uniformly arranging a plurality of contact points (first contact points 11 and second contact points 21) at the edges of the metal sheets (first metal sheet 10 and second metal sheet 20), the first metal sheet 10 and the second metal sheet 20 can be electrically contacted better.
In this embodiment, in order to prevent an excessive gap between the first metal sheet 10 and the second metal sheet 20 when they are in contact with each other, fixing points 30 are provided on the surface of the first metal sheet 10 at predetermined intervals.
The distance between the two fixing points 30 should not be too large or too small, and it is preferable to provide one fixing point 30 every two first contact points 11 to ensure that the first metal sheet 10 and the second metal sheet 20 are sufficiently bonded together.
Specifically, the fixing points 30 may be a hot melt paste which is in a molten state at a high temperature and has a good viscosity, and may tightly bond the first metal sheet 10 and the second metal sheet 20 together.
In some embodiments, a plurality of conductive sheets 40 may be further attached to the surface of the first metal sheet 10, and in particular, the conductive sheets 40 may be copper foil, aluminum foil, or other materials with conductive properties.
The conductive sheet 40 increases the electrical contact area between the first metal sheet 10 and the second metal sheet 20, thereby reducing the impedance between the first metal sheet 10 and the second metal sheet 20, so that the static electricity can be more sufficiently discharged.
In this embodiment, before the ESD test is performed on the metal sheets (the first metal sheet 10 and the second metal sheet 20), the first metal sheet 10 is grounded (not shown in the figure), and the electrostatic charges on the metal sheets (the first metal sheet 10 and the second metal sheet 20) are transmitted to the ground through the ground via the contact points (the first contact point 11 and the second contact point 21) that are in contact with each other, so that the electrostatic accumulation is not formed on one metal sheet, and a potential difference is formed between the metal sheet and a motherboard (not shown in the figure) of the metal sheet splicing type chassis (computer), so that the ESD test cannot pass.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
