New description: [New technical field] This creation is about the improvement of the fixing piece of EM I mask, especially the fixing piece of EMI mask which can quickly disassemble the EMI mask. . [Prior Art] As is well known, almost all electronic products generate the problem of Electromagnetic Interference (EMI) during operation, and electromagnetic interference refers to the electromagnetic induction effect caused by the electrical product itself. The interference caused by electromagnetic waves on surrounding electronic equipment, and also because electromagnetic interference can cause other electrical equipment to work interrupted, abnormal shutdown, increased maintenance, crosstalk and system delay 'and human injury, etc., therefore, advanced countries for electronic products Electromagnetic problems are regulated by legislation. Therefore, the product must be excluded from the possible electromagnetic problems in the planning and design. If it is not carefully considered in the initial design, the precision design of the entire product from the external device such as the outer casing, the slot and the aperture to the internal component arrangement and materials. When the test fails later, the cost will be much larger than the original estimate. In order to meet the above requirements, some specific electronic components on the circuit board will be additionally covered with EMI mask to avoid the electromagnetic radiation effect. The EMI mask commonly used in the industry is an integrally formed cover having a top wall and a support arm extending perpendicularly from the periphery of the top wall. In use, the cover is placed on the electronic component to be shielded, and the support arm is fixed to the circuit board on which the electronic component is mounted by soldering or the like. However, in the actual production of 3 16984 f maintenance process, when the electronic component appears _, the engineer needs to remove the shield and then remove it before viewing the electronic section. The upper cover makes it inconvenient for engineers to perform maintenance. [New content] In view of this, the present invention provides an improved EMI mask, which can quickly improve the EMI mask for the fixed mask of the masking industry. I, for the above purpose of the creation of the present invention, the fixing piece conforming to the EMI mask of the present invention comprises at least: a seat body and a clamp, the seat body is provided with at least one flat portion, and the flat portion has an extension extending straight on both sides thereof. The clamp is provided with a spring piece extending from the extension portion and standing upright toward the soil, and each elastic piece is close to the top portion and is formed with a convex 4' inwardly. The side plate of the Ι mask can be inserted into the clamp, and the side plate of the Xie mask is arranged There is at least a protruding portion for the convex portion of the clamp to be fixed on the convex portion to achieve a fixed effect, or to be pulled upward (four) simple separation operation and [embodiment] A clear understanding of the drawings and the detailed description of the embodiments is provided. The basic structure of the "Fixed Fixture Improvement for ΕΜΙ ΕΜΙ 本" is shown in the first and second figures. Included at least: a body plus clip and 12; 苴 middle: , - the seat body 11 is provided with at least - flat (four) lu ′. The flat portion ln (four) straight line extends with an extension 112. The clamp 12 is disposed on the money extension portion 112. The elastic member 121 is provided with an elastic piece 121 extending upward from both sides of the extension M416984 extension portion 112. Each elastic piece 121 is formed near the top portion and has a convex portion 122 formed inwardly. An outer sheet form is formed above the portion 122. When used as a whole, as shown in the third figure, the fixing piece can be fixed on an electric board 2, and another EMI mask 3 can be used by the fixing piece! The EMI mask 3 is provided with a plurality of side plates 31 for fixing the fixing piece 1 , and each side plate 31 is provided with at least one protruding portion 31. Please refer to the fourth figure at the same time. The two elastic pieces 121 have a considerable elastic space, and the convex portion 122 is elastically applied by the elastic piece 121 to have the function of sandwiching the side plate 31 of the EMI mask 3, and the top portion forms the outer-shaped convex portion 122. Then, the guiding side plate 31 enters the elastic piece 121 according to the protruding portion 122, so that the protruding portion 311 of each side plate can be fixed and fixed in the lower portion of the convex portion 122 to achieve a fixing effect. In addition, the flat portion 11 丨 and/or the extending portion 112 is provided with at least one notch. As shown in the first drawing, when the fixing structure is welded to the one-way board, the notch 113 can be added to the contact area of the solder to strengthen the same. Soldering effect. .
