Description

Electronic equipment

The invention relates to an electronic device, in particular to an electronic device for preventing electromagnetic interference of a cable.

Cables (flexible circuit boards, FPC) are widely used in various electronic products, which generate EMI (Electromagnetic Interference) during operation. However, the EMI generated by the cable is often amplified by the Shielding inside the electronic product, so that the EMI of the electronic product does not meet the relevant requirements. In order to solve the above problems, the existing methods generally use a conductive cloth to wrap the cable, the cable outer casing magnetic ring or the cable connector to the conductive foam and then ground the ground to make the EMI of the electronic product meet the relevant requirements. However, these methods of preventing EMI result in an increase in the cost of electronic products due to the need to add additional parts such as conductive cloth, magnetic rings or conductive foam.

In view of this, it is necessary to provide an electronic device with lower cost and anti-wire electromagnetic interference.

An electronic device includes a housing, a cover, a cable, a first circuit board, and a second circuit board. The housing is configured to fix and receive the matte, the wire, the first circuit board, and the second circuit board. Electrical connection Connected between the first circuit board and the second circuit board. The mask is disposed on one side of the cable. The mask is provided with an opening corresponding to the cable.

Preferably, the shape of the opening matches the shape of the wire.

Preferably, the size of the opening is larger than the size of the wire.

The electronic device can prevent electromagnetic interference by opening an opening corresponding to the cable on the cover sheet, and does not need to add additional parts, thereby reducing the cost of the electronic product.

Please refer to FIG. 1 , which is an exploded perspective view of an electronic device 100 according to a preferred embodiment. The electronic device 100 includes a housing 10, a mask 20, a cable 30, a first circuit board 40, and a second circuit board (not shown). The housing 10 is for fixing and housing the mask 20, the cable 30, the first circuit board 40, and the second circuit board (not shown). In the present embodiment, the electronic device 100 is a DVD player. In other embodiments, the electronic device 100 can be a notebook computer, a mobile phone, and other electronic products with cable.

The housing 10 includes a bottom plate 11 and studs 12 disposed on the bottom plate. Where the bottom plate 11 is used to carry the mask 20, the cable 30, and the first circuit board 40. The stud 12 is used to secure the matte 20, the wire 30, and the first circuit board 40 to the bottom plate 11. In the present embodiment, the number of studs is 4 and symmetrically disposed on the four corners of the bottom plate 11.

The matte 20 is fixed to the housing 10. The mask 20 is provided with an opening 21 corresponding to the wire 30 and a first screw hole 22 cooperating with the stud 12 . Among them, the shape of the opening 21 matches the shape of the wire 30. In the present embodiment, the size of the opening 21 is slightly larger than the size of the wire 30. The number of the first screw holes 22 is two.

The cable 30 is disposed on a side of the mask 20 away from the housing 10. The cable 30 is electrically connected to the first circuit board 40 and the second circuit board (not shown). The cable 30 includes a first end 31 and a second end 32. The first end portion 31 is for connecting with the first circuit board 40, and the second end portion 32 is for connecting with the second circuit board (not shown). In the present embodiment, the cable 30 is substantially rectangular.

The first circuit board 40 is disposed on a side of the cable 30 away from the mask 20. The first circuit board 40 includes a second screw hole 41 for locking with the stud 12 and a plug portion 42. The plug portion 42 is configured to be inserted into the first end portion 31 of the cable 30 to electrically connect the first circuit board 40 and the second circuit board (not shown). In the present embodiment, the first circuit board 40 is used to control the operation of the optical disk drive, and the second circuit board (not shown) is used to control the operation of the electronic device 100. The number of the second screw holes 41 is four.

Referring to FIG. 2 and FIG. 3 , when assembled, the stud 12 passes through the first screw hole 22 and the second screw hole 41 in sequence, and is locked in the second screw hole 41 , so that the mask 20 is fixed to the shell. Between the body 10 and the first circuit board 40. The cable 30 is disposed between the mask 20 and the first circuit board 40 and is opposed to the housing 10 through the opening 21. The first end portion 31 is inserted into the plug portion 42, the second end portion 32 and the second circuit board (not shown) )connection.

Please refer to FIG. 4 again, which is a schematic diagram of the electronic device 100 against EMI. When the opening 20 is opened in the mask 20, the EMI generated during the operation of the wire 30 is diffused toward the casing 10 through the opening 21, which is not amplified by the mask 20 and reflected back to the inside of the electronic device 100. That is, the amplification path of the EMI generated by the cable 30 is cut off, thereby providing an anti-EMI effect.

The electronic device 100 can provide an anti-EMI effect by opening the opening 21 corresponding to the cable 30 on the mask 20, without adding additional parts, and reducing the production cost of the electronic product.

In summary, the new model complies with the new patent requirements and submits a patent application according to law. However, the above is only a preferred embodiment of the present invention. Any equivalent modifications or variations made by those skilled in the art of the present invention should be included in the following claims.
