Description

TECHNICAL FIELD

[0001] The utility model relates to communication and electronic technology field especially relates to a front interface board with dustproof structure. BACKGROUND

[0002] The front interface board is the interface board of the front or top of the case. It contains some interfaces convenient for user access, such as USB interface, audio interface (earphone and microphone interface), card reader, etc. These interfaces are mainly used to connect temporary external devices, such as USB flash drive, earphone, microphone, etc., so that the user does not have to operate from the back of the case. Compared with the interface at the back of the mainboard, the front interface is used more frequently, providing convenience for daily use of the user. When installing or connecting the front interface board, attention should be paid to the correspondence of each interface and plug, to ensure correct connection and normal use of the equipment.

[0003] At present, the common dustproof structure of the front interface board is generally a turnover dust cover, that is, a turnover cover plate that can be turned over and opened is installed on the front of the front interface board, and when not in use, the input port on the front interface board can be covered and protected, so as to prevent external dust from entering the inside.

[0004] However, the dust cover can only play a dustproof role when the input end of the front interface board is not inserted with an external plug, and when the external input plug is inserted, the dust cover will be blocked from closing, and the input end of the front interface board is exposed to the external air, so dust will still enter the inside, and the dustproof effect is relatively poor.

[0005] Therefore, it is necessary to design a front interface board with dustproof structure to solve the above problems. CONTENT OF THE UTILITY MODEL

[0006] The utility model provides a front interface board with dustproof structure solves the technical problem proposed above.

[0007] In order to solve the above technical problem, the utility model provides a front interface board with dustproof structure, which comprises a front interface board, an audio input end is installed on the upper part of the front of the front interface board, a USB interface end and a network interface end are installed on the lower part, dustproof limiting structures are fixedly installed on the front of the front interface board, and the audio input end, the USB interface end and the network interface end are covered.

[0008] Preferably, the dustproof limiting structure comprises a protective cover frame and a protective plate, an opening is formed in the outer end of the protective cover frame, a sliding groove is formed in the side end of the protective cover frame close to the opening position, a slot is formed in the other side end of the protective cover frame and communicated with the sliding groove, the protective plate is inserted into the sliding groove to block the opening of the protective cover frame, and a magnetic sealing structure is arranged in the middle of the protective plate.

[0009] Preferably, the protective plate has a sliding groove extending through the slot at one end.

[0010] Preferably, the magnetic sealing structure includes a magnetic rubber sheet one and a gear rubber sheet two. A connecting groove is provided in the middle of the protective plate and the protrusion, and the magnetic rubber sheet one and the gear rubber sheet two are fixedly connected to the opposite ends of the connecting groove.

[0011] Preferably, the magnetic rubber sheet one and the gear rubber sheet two are different magnets, and the magnetic rubber sheet one and the gear rubber sheet two are magnetically connected and sealed.

[0012] Preferably, both the protective cover frame and the protective plate are made of transparent acrylic sheet.

[0013] Compared with related technologies, the front interface board with a dustproof structure provided by this utility model has the following beneficial effects:

[0014] This utility model provides a dustproof limiting mechanism that covers and protects the audio input terminal, USB interface terminal, and network cable interface terminal, preventing external dust from entering them. When an external connector is inserted into the front interface board, the protective plate is pushed back into the protective cover frame, and the connecting wire of the external connector enters the connecting groove of the protective plate. The groove is sealed by a magnetic sealing structure, thus minimizing the communication channel with the outside while still providing dustproof protection. Furthermore, the connection between the protective plate and the protective cover frame ensures that if the connecting wire of the audio plug, USB connector, or network cable connector is pulled later, the protective plate will limit its movement, preventing it from easily detaching from the front interface board.
