Embodiment 1

[0025] Such as Figure 2-3 As shown, the side wall of the end where the card tray 1 is connected with the card holder cap 2 is provided with a first groove 11, and the bottom wall of the first groove 11 is provided with a second groove 12, and the first groove 11 There is a step between the bottom wall of the second groove 12 and the bottom wall of the second groove 12 . Wherein, at least one connecting column 13 is formed on the bottom wall of the second groove 12, and a through hole 22 corresponding to the connecting column 13 is opened on the card tray cap 2, and the card tray cap 2 is sleeved on the connecting column through the through hole 22. Column 13. In this embodiment, the number of connecting columns 13 is two, and in other embodiments, the number of connecting columns 13 may also be one or more.

[0026] At least one locking portion 14 is formed on the bottom wall of the second groove 12 , and an engaging hole 23 is opened on the cap 2 , and the engaging hole 23...

Embodiment 2

[0035]The difference with embodiment 1 is: the Cato cap 2 is still a Cato cap made of conductive metal, and an oxide film layer is formed on the surface of the Cato cap 2, and the Cato cap 2 is connected with the first conductive part 31. The corresponding position is protruded with a protrusion as the second conductive part 21, and the protrusion is exposed to the outside through the oxide film layer. The groove is coated with a conductive metal layer or the soldering part 3 is made of conductive metal. Wherein, the conductive metal and the conductive metal layer can be made of aluminum, aluminum alloy, copper, gold or silver.

[0036] The antistatic card support structure of this embodiment is an alternative structure of Embodiment 1, which can also realize the export of static electricity generated by aggregation, realize the antistatic effect, avoid adverse effects on the performance of mobile phones, and improve user experience Spend.

[0037] The serial numbers of the ...

Abstract

The invention relates to an anti-electrostatic card tray structure, comprising a card tray and a card tray cap mounted at one end of the card tray. The card tray cap and the card tray are relatively movably connected through a welding component. The welding component is equipped with at least one first conductive part. The card tray cap is equipped with a second conductive part connected with eachfirst conductive part. The first conductive part and the corresponding second conductive part are in mutual butt joint. According to the anti-static card tray structure, the first conductive part connected with the second conductive part on the card tray cap is set on the welding component, so static electricity generated by aggregation is exported, an anti-electrostatic effect is realized, the bad influence on the mobile phone performance is avoided, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to an antistatic card support structure. Background technique [0002] At present, in order to improve the position and gap uniformity between the card cap and the middle frame hole, the mobile phone usually uses a combined structure of the card cap and the card tray that can move slightly. The card cap and the card tray of this structure are movable, and there is a slight gap between them. When the card cap is made of aluminum alloy, a non-conductive oxide film will be formed on the surface after the anodic process, so that the user During use, the Cato cap is likely to generate static electricity due to friction and accumulate on the Cato cap and cannot be exported, which affects the performance of the mobile phone. Contents of the invention [0003] The purpose of the present invention is to provide an anti-static card holder structure to solve the problem of static e...
