Problems solved by technology

[0005] Aiming at the above technical problems, the present invention proposes an assembly method of the shielding cover structure at an ultra-low height, which breaks the conventional concept of the cooperation between the convex shell and the hole of the shielding cover. The defect that it is difficult to separate the outer cover after reassembly and easy to loosen after reassembly can greatly effectively improve and ensure the assembly quality of the shielding cover

Embodiment 1

[0027] An assembly method for the structure of the shielding case at an ultra-low height, including a built-in shielding case 2 and an external shielding case 1, the edge of the built-in shielding case 2 is provided with a stacking hook 3, and the edge of the external shielding case 1 is provided with an angle The bending buckle 4, the stacking hook 3 and the angle bending buckle 4 can form a buckle, so that the built-in shielding cover 2 and the external shielding cover 1 can form an ultra-low height assembly structure with a height of 0.5mm through the butt joint of the stacked materials. At the same time, the stacking hook 3 has a U-shaped structure without gaps, and the bending angle of the angle bending buckle 4 is 30°. The two cooperate with each other to form a two-way bending of the shielding cover in the mold, and finally use the external cover Angle bending buckle at the overlapping material of the inner cover to form an inverted buckle to complete the assembly combin...

Embodiment 2

[0029] An assembly method for a shield structure at an ultra-low height, including a built-in shield 2 and an external shield 1, the edge of the built-in shield 2 is provided with overlapping hooks 3, and the stacking hooks 3 are evenly distributed on the built-in shield On each long side of the cover 2, the edge of the external shielding cover 1 is provided with an angle bending buckle 4, and the angle bending buckle 4 is evenly distributed on each long side of the external shielding cover 1, and the stacking hook 3 Corresponding to the positions of the angle bending buckles 4, evenly distributed on each side can make the stamping die design simpler, the modules can be interchanged, easy to maintain, and low in cost.

[0030] The stacking hook 3 and the angle bending buckle 4 can be pressed vertically downward through the bending bullnose of the built-in shielding cover 2 to form a buckle, so that the built-in shielding cover 2 and the external shielding cover 1 can be formed ...

Abstract

The present invention discloses an assembly mode of a shield case structure in an ultra low height, belonging to the technical field of shield structures. According to the assembly mode, product superposition small bending mode locking assembly is used, the limit that a conventional convex hull and hole for a shield case can not be processed in an ultra low height is broken, the two-way bending of the shield case is completed in a mold, finally the angle bending of an external cover is buckled at the superposition part of an internal cover, reverse buckling is formed to complete assembly combination, and thus the defect of no processing in the traditional mode is avoided. Since the mutual buckling mode of the shield case is bending and connection, in a condition of shield case repair, the shield case can be conveniently lifted by using tweezers to gently the shield case outward. The assembly mode has the advantages of simple structure and high practicability, a defect that the external cover of a shield case product is difficult to separate after assembly and is easy to be loose after recombination in a traditional mode can be solved, and the assembly quality of the shield case can be greatly improved and ensured.

Description

technical field [0001] The invention belongs to the technical field of shielding cover structures, and in particular relates to an assembly method of a shielding cover structure at an ultra-low height. Background technique [0002] With the rapid development of science and technology, the application of various high-tech electronic products is becoming more and more popular, but it also brings many problems, such as the electromagnetic interference problem encountered in the use of electronic products, which not only interferes with the electronic products The normal use, but also has an adverse impact on the surrounding environment. The function of the shielding cover is to form an electromagnetic shield to prevent electromagnetic interference. Shielding cover parts are mainly used in mobile phones, GPS and other electronic fields to prevent electromagnetic interference (EMI) and shield components on PCB boards and LCM. [0003] At the same time, the trend of ultra-thin a...
