M250211 IV. Creation Instructions (1) The new technology belongs to this field. This creation relates to a partition structure and a computer case using the partition structure, and in particular to a type suitable for blocking electromagnetic wave interference (Electromagnetic interference, EMI). ) Partition structure and computer case using the partition structure. Previous technology With the rapid advancement of electronic technology, various electronic products have been increasingly used in our work and life, especially the most common electronic products such as information and home appliances. Undoubtedly, computers have become one of the necessities of life and work for today's human beings, regardless of servers, workstations, desktop computers, or notebook computers. ), And even industrial computers, computers have gradually become an indispensable and important tool in ordinary people's life and work. Taking a computer as an example, it can be roughly divided into a host part, a display and peripheral equipment. Among them, the host part also includes a computer case, and the inside of the computer case is equipped with a motherboard, a floppy disk, a hard disk, a CD-ROM, Electronic components such as power supply. When the computer is operating, each electronic component will be accompanied by electromagnetic waves, and the generated electromagnetic waves will cause electromagnetic interference to each other. FIG. 1 is a schematic diagram of a conventional computer host. The computer casing 100 is mainly composed of a casing 110 and a conductive partition 120. The conductive partition 120 is disposed inside the casing 110 'and divides the internal space of the casing 110 into two

12943twf.ptd Page 6 M250211 4. Creation instructions (2) compartments. One of the compartments is provided with a power supply 130 and an optical disc drive 140, and the other compartment is provided with a motherboard 150. Due to space utilization considerations, a motherboard riser 160 is vertically connected to the motherboard 150 to provide, for example, an ISA (Industry Standard Architecture) slot and an IDE (Integrated Device)

Electronics) slot, power supply slot ... etc. The interface expansion card 160 is fixed on the conductive partition 120. The conductive partition 1 2 0 has an opening 〇 1 so that the power cord of the power supply 丨 3 〇 and the bus line 1 (ne) of the optical disc drive 140 can be connected from the opening 〇 丨 to the interface expansion Card 160. Because the interface expansion card 160 often uses, for example, a dual in-line package (DIP) or other electronic components with pins, pin holes are formed on the interface expansion card 160. Therefore, the electromagnetic waves generated during the operation of the motherboard 150 will pass through the pin holes ′ of the interface expansion card 160 and pass through the opening 〇1 of the conductive spacer 120 to escape from the gap of the housing 丨 20. Of course, the electromagnetic waves generated by the power supply 丨 3 〇 and the optical disk drive 丨 4 〇 will also spread to the main board 150 in the same path, thus causing electromagnetic wave interference to the main board 150. ^ Since electromagnetic wave interference not only affects the electronic components inside the computer, but also may cause human health hazards, countries have strict regulations on the intensity of electromagnetic waves generated by electronic products. Therefore, 'how to reduce the electromagnetic interference caused by each component of the host computer during operation' and to prevent electromagnetic waves from overflowing and endangering human health has become an important issue. New type of intercourse

12943twf.ptd Page 8 M250211 4. Creation Instructions (4) It is fixed to the opening of the conductive partition by screws. The material of the conductive spacer and the conductive cover is, for example, metal. In summary, in the partition structure of this creation and the computer case to which this partition structure is applied, a conductive cover is arranged at the opening of the conductive partition. Therefore, the electromagnetic waves generated by the electronic components on both sides of the conductive partition can be leaked to the shell of the computer case and grounded through the conductive cover, without double rows from the opening of the conductive partition and the interface expansion card. The pin holes of the electronic components of the type package diffuse to the other side of the conductive spacer, thereby reducing the electromagnetic interference of the host computer to the outside and the inside. In order to make the above and other objects, features, and advantages of this creation more comprehensible, the following describes the preferred embodiments in detail with the accompanying drawings, as follows. Embodiment FIG. 2 is a schematic diagram of a partition structure of a preferred embodiment of the present invention and a computer case using the partition structure, and FIG. 3 is a schematic view of the partition structure of FIG. 2 from another angle. . Referring to FIG. 2, the computer case 200 is suitable for receiving at least one motherboard 250 and an interface expansion card 260. The interface expansion card 260 is vertically connected to the motherboard 250. The function of the interface expansion card 260 is mainly to save space on the motherboard 250, and the ISA slot, IDE slot, power supply slot, etc. are arranged on the interface expansion card 260 to make full use of the computer The internal space of the shell 2 0 0. Please refer to FIG. 2 and FIG. 3, the computer casing 200 is composed of a casing 210 and a partition structure 2 2 0. The partition structure 2 2 0 is composed of a conductive partition 2 2 2 and a conductive cover 2 2 4. The conductive partitions 2 2 2 are arranged in the housing 210,

12943twf.ptd Page 9 M250211 4. Creation Instructions (5) The inner space of the housing 2 10 is divided into two compartments. A power supply 2 3 0 and an optical disk drive 2 40 are, for example, disposed in a compartment on one side of the conductive partition 2 2 2, and the motherboard 250, the interface expansion card 260, a floppy disk drive 270, and a fan 2 8 0 is, for example, disposed in a compartment on the other side of the conductive partition 2 2 2. Among them, the interface expansion card 2 60 is fixed on the conductive partition 2 2 2. In order to enable the power supply line of the power supply 230 and the bus line of the optical drive 2 40 to be connected to the entrance expansion card 260, an opening 〇2 is formed on the conductive partition 222, and the interface expansion card 260 is exposed at 1. Such as IDE slot and power slot. —, Please continue to refer to FIG. 2 ′ The conductive cover 2 2 4 is disposed at the opening 02 of the conductive partition 2 2 2. In this embodiment, the interface expansion card 260 is located between the partition 222 and the conductive cover 224, for example. Of course, the interface expansion card 26 and the electric cover 2 24 can also be located on both sides of the conductive partition 22 2, that is, the cover 2 2 4 is arranged at the opening of the conductive partition 2 2 2. It is shown on the first electrical side of FIG. 3. First, since the outer casing 210 and the conductive partition 2 2 2 of the computer case 2 2 2 and the conductive plate 2 2 4 are all conductive materials such as metal, so whether it is the host computer, the optical disc drive 2 4 0 or the power supply 2 3 The electromagnetic waves emitted by the 0 component, the conductive cover 224 are guided to the conductive partition 222 and the housing 210 and grounded. This can greatly improve the electromagnetic interference caused by the opening of the electromagnetic and French conductive partition 22 and the conductive sheet of the interface expansion card 26 when the conductive cover 2 24 is not provided. And reduce the possibility of electromagnetic waves escape ^ '2 00. ΏMotor housing In addition, the interface expansion card 2 6 0 is located in the part covered by the conductive cover 2 24.
