Description

A kind of antimagnetic lid

Technical field:

The utility model relates to a kind of antimagnetic lid.

Background technology:

Along with the rapid progress of science and technology, many electronic products all move towards light and handy design, therefore, no matter also just limit to some extent on configuration space or volume in relevant electronic building brick.Because integrated circuit more is tending towards intensive development, the situation of electromagnetic interference also just becomes stubborn problem between various electronic building brick, particularly for chip with powerful operational performance, the high frequency environment that it is produced in calculating process, the electromagnetic interference of other electronic building brick be certainly will cause, thereby the stability and the useful life of electronic product influenced.

Yet, in view of the foregoing, existing settling mode is exactly the ㄇ type mask that is provided with a metal in the specific electronic building brick of circuit board, be covered on this electronic building brick, be commonly called as and be antimagnetic lid, by this to block electronic building brick itself or extraneous being generated electromagnetic waves or phase mutual interference that static was caused.

Take off known antimagnetic lid in preceding, the mode on the circuit board of generally being fixedly arranged on generally is divided into three kinds: a kind of is that mode with buckle is fixedly arranged on it on circuit board; Another kind is to utilize locking part to be fixed; The third is the mode with electric welding, and weld in the limit that is connected with circuit board around the antimagnetic lid of metal; Described three kinds all can be fixed in antimagnetic lid on the circuit board, and the interference of blocking electromagnetic wave or static with the covering specific electronic components is a purpose.

Yet above-mentioned buckle mode needs need be drilled with fixing hole on circuit board, and it not only damages for circuit board, under the trend of microminiaturized consideration at present, and the inconvenience that will cause circuit board line to arrange; Other is in the mode that locking part sets firmly, though it is convenient to the assembling and the dismounting of antimagnetic lid, this method need spend higher assembly cost (human cost just) in addition, and the manpower operation must influence its precision and yield problem; The electric welding mode then is discussed at last, but because electric welding mode cording has automation, and with antimagnetic lid can be firm set firmly, therefore, this method is still the industry institute processing mode of acceptance the most; Yet, this method but is that the maintenance personal fears to face most, because this mode need be by special tool when maintenance, and expend the more time with the weld scolder of establishing, fusion is one by one removed just and antimagnetic lid can be removed, if short circuit that will cause other integrated circuit package because of carelessness in the process of maintenance is real in causing anxiety.

Therefore, how to consider that the assembling of antimagnetic lid is certain and quick, and consider the removal problem of follow-up maintenance simultaneously, just become and make the direction that antimagnetic lid dealer is researched and developed.

The utility model content:

Technical problem to be solved in the utility model is: at the deficiencies in the prior art, a kind of antimagnetic lid is provided, the advantage that can utilize weldering to establish mode is fixedly arranged on framework on the circuit board, utilize the mode of buckle to make loam cake and framework assembling again, with certain antimagnetic lid is set firmly, consider follow-up maintenance problem simultaneously again by this.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of antimagnetic lid, it includes a framework and a loam cake, described loam cake is a metal plate body, and in around be formed with at least one or more than one buckle bull, and between each buckle bull, be provided with groove; Described framework is a metal containment body, is provided with leg in the containment body lower edge, and is formed with and the corresponding buckle parent part of the buckle bull of loam cake around containment body, and is provided with groove between each buckle parent part.

The buckle bull of described loam cake comprises a tenon sheet, is formed with a protuberance on this tenon sheet.The buckle parent part of described framework comprises wears groove, and this is worn on the vertical face containment body of groove correspondence and is formed with a location hole.The groove of described loam cake is corresponding with the groove of framework, and is formed with a gap for the maintenance tool insertion after loam cake and framework embedding group.

Compared with prior art, the utility model has the advantages that: the mode of utilizing weldering to establish is fixedly arranged on framework on the circuit board, with reach whole antimagnetic lid be fixedly arranged on the circuit board really; Utilize the design of buckle bull and parent part, make the assembling of loam cake and framework, be convenient to the dismounting maintenance, have the function of freely tearing group open to finish antimagnetic lid; Framework and loam cake are processed synchronous forming via punching out, not only consider the stability of same processing and forming environment, and simplify the moulding processing steps.
