Anti-signal-leakage closed structure and access cabinet

Abstract

The invention belongs to the technical field of signal shielding and access cabinets, and discloses an anti-signal-leakage closed structure and an access cabinet. The anti-signal-leakage closed structure comprises a male structure and a female structure. The male structure is provided with a plurality of first bulges at intervals. A plurality of first grooves are formed in the female structure at intervals, the first grooves correspond to the first bulges in a one-to-one mode, the first bulges abut against the first grooves, and signal shielding faces are formed on the abutting faces of the first bulges and the first grooves. Signal absorption cavities are formed in the gaps between the first bulges and the first grooves. The signal shielding faces can effectively prevent signal leakage, and the signal absorption cavities can absorb leaked signals, so that complete shielding of the signals is realized. The access cabinet adopts the anti-signal-leakage closed structure. Signals emitted by an RFID signal transmitter in the cabinet can be completely shielded, and meanwhile, the comfort of a user when a cabinet door is closed is improved.

Description

technical field [0001] The invention relates to the technical field of signal shielding and access cabinets, in particular to an airtight structure for preventing signal leakage and an access cabinet. Background technique [0002] There are two main ways for existing access cabinets to prevent the leakage of RFID signals (Radio Frequency Identification) in the cabinet; the first is to tightly compress the access cabinet door, so that the signal sealing strip between the cabinet door and the cabinet body is compacted. , in order to achieve the shielding of the RFID signal in the cabinet, but this method is not comfortable to close the door, requiring the user to use a lot of force to close the cabinet door completely, and the cabinet door will be slightly deformed after repeated use, resulting in a The signal sealing is not strong, resulting in signal leakage; the second is to transmit directional RFID signals into the cabinet through a directional RFID signal transmitter.

[0002] There are two main ways for existing access cabinets to prevent the leakage of RFID signals (Radio Frequency Identification) in the cabinet; the first is to tightly compress the access cabinet door, so that the signal sealing strip between the cabinet door and the cabinet body is compacted. , in order to achieve the shielding of the RFID signal in the cabinet, but this method is not comfortable to close the door, requiring the user to use a lot of force to close the cabinet door completely, and the cabinet door will be slightly deformed after repeated use, resulting in a The signal sealing is not strong, resulting in signal leakage; the second is to transmit directional RFID signals into the cabinet through a directional RFID signal transmitter. The design principle of this method is that the scattered RFID signals only face a single direction in the cabinet to ensure RFID The signal will not leak to the outside of the cabinet, but the cost of the directional RFID signal transmitter is very high, and since the directional RFID signal transmitter can only transmit signals in a single direction, there are signal identification dead spots in the cabinet, and the identification dead spots have not been solved Two directional RFID transmitters need to be placed in the problem cabinet, which increases the manufacturing cost of the access cabinet product
