Description

Cover lock structure of notebook computer case

The present invention relates to a technical field of anti-electromagnetic interference design of a notebook computer case, in particular to a cover locking structure of a notebook computer case which has a simple structure, does not fall off and has a grounding effect.

In addition to the central processing unit (CPU), the motherboard of a typical notebook computer is provided with a number of mating chips and connectors for various computer peripheral devices. With these different connectors, the peripheral components of the computer can be added. link. The main accessories, such as hard disk (HDD), optical disk drive (ODD) and solid state drive (SSD), are generally built-in devices that are selectively installed during the assembly phase of the computer.

Whether it is a hard disk, a CD player or a solid-state hard disk, since the connector has a parallel connection structure and many signal transmission lines, it is easy to transmit signals due to excessive transmission loops and insufficient shielding. Generate Electromagnetic Interference (EMI) problems.

In order to solve the problem of EMI, the inner surface of the computer case is usually plated with a metal film to form a shield or as a grounding, and various wafers, devices, and the like on the motherboard must be grounded.

However, in order to facilitate maintenance, replacement or installation of a hard disk, a memory, etc., the cover of the notebook computer is usually provided with at least one cover that can be opened, and a gap between the cover and the casing is likely to form a shielding hole. Therefore, a common practice is to ground the cover between the cover and the housing to achieve the effect of preventing EMI.

Please refer to FIG. 1 , which is a schematic diagram of the ground structure of the existing notebook computer case and cover. The housing 80 has an opening 81 and the housing 80 is at the periphery of the opening 81 The base portion 82 is formed with a stepped structure formed between the housing 80 and the opening 81. A cover 90 is disposed relative to the abutment portion 82. The cover 90 is provided. The shape is matched with the abutting portion 82, and one side of the abutting portion 82 is provided with two nuts 85 for the purpose of burying the cover body 90 for locking the cover body 90, and the abutment The other three sides of the portion 82 are respectively provided with a plurality of grounding elastic pieces 83. The cover body 90 is provided with a conductive foil 91 corresponding to the position of each of the grounding elastic pieces 83. Thus, when the cover body 90 is locked by the screw 92, When the abutting portion 82 is formed, the respective conductive foils 91 of the cover 90 can press the grounding elastic piece 83 to generate a grounding effect, thereby achieving the effect of preventing EMI problems.

Referring to FIG. 2 again, it is a schematic cross-sectional structural view of the grounding elastic piece and the cover body and the abutment portion. The grounding elastic piece 83 has a flat connecting portion 831 and an elastic portion 832 having an arc shape, and the abutting portion 82 is provided with a through hole 821 corresponding to the elastic portion 832, so that the elastic portion 831 can be protruded from the through hole 821. The inner surface of the abutting portion 82 (ie, the inner surface of the housing) is plated with a metal film 84, and the connecting portion 831 corresponding to the grounding elastic piece 83 is provided with a heat-melting column 822, The connecting portion 831 of the grounding elastic piece 83 is fixed to the inner surface of the abutting portion 82 and is in contact with the metal film 84. After the cover 90 is mounted, the conductive foil 91 on the inner surface thereof is formed by hot-melt bonding. Then, the elastic portion 832 of the grounding elastic piece 83 is pressed, so that the respective conductive foils 91 of the cover 90 can be electrically connected to the metal thin film 84 via the grounding elastic piece 83 to generate a ground.

However, the foregoing grounding elastic piece 83 is fixed by the heat-melting column 822, but after the locking body is mounted, the cover body 90 is always pressed against the elastic portion 832, and the grounding elastic piece 83 is continuously generated to be disengaged from the heat. The force of the direction of the molten column 822 is pressed. Therefore, once the hot-melt column 822 has a hot-melt pressing failure, it is easy to fall off the grounding elastic piece 83 when the notebook computer is used in the future, and the grounding elastic piece 83 is dropped onto the main board. A problem that causes a short circuit in the circuit to cause a burn.

Therefore, the foregoing structure is still necessary for further improvement.

In view of this, the main purpose of the present invention is to solve the above problems and provide a notebook computer case that has a simple structure and does not fall off, and can surely reach the grounding effect. The cover of the body is locked.

For the purpose of the above, the cover locking structure of the notebook computer case is mainly composed of a casing, at least one nut and a cover plate, the casing has an opening, and the periphery of the opening is convex.
