Description

Technical Field

[0001] The utility model generally relates to the technical field of electronic signal anti-interference, and in particular to an electronic signal anti-interference device for a subway vehicle. Background Art

[0002] For the railway system, in order to ensure the security of data, data transmission is generally carried out within the local area network. During the transmission process, this type of data needs to rely on terminal devices such as laptops and mobile phones to connect to a specific local area network for data transmission within the specific local area network.

[0003] For this type of data transmission work, the transmission process is easily affected by electromagnetic interference generated by power transmission lines, etc., thus affecting the stability of data transmission. Therefore, special anti-interference equipment is generally installed on the subway or along the road. However, the anti-interference equipment is generally fixed, and the anti-interference effect is not ideal when it is far away from the terminal device. In view of this problem, the Chinese utility model patent with application number 202222540955.9 discloses an anti-interference structure, which is provided with a mounting plate and a side card plate. An anti-signal jammer is provided on the mounting plate. The terminal devices such as notebooks and mobile phones can be clamped and fixed by the side card plate, so that the anti-signal jammer can be connected easily, and the anti-signal jammer can be moved with the data transmission equipment, thereby effectively solving the problem of being interfered with when the distance from the anti-interference equipment is far.

[0004] However, since a plug-in plate is provided on the side card plate, the plug-in plate can be plugged into and matched with the mounting plate, and the plug-in plate is locked or fixed by a bolt assembly to adjust the position of the side card plate, thereby achieving the purpose of connecting or separating with the terminal device. This method of operation requires locking or loosening the bolt assembly to achieve adjustment, which is not convenient enough to operate and use. Utility Model Content

When in use, it is only necessary to overcome the elastic force to move the side card plate, and then release the data transmission device to achieve the clamping.
