Description

Technical Field

[0001] The invention relates to the technical field of communication vehicles, and in particular to an electromagnetic protection device for a power wall box and a signal introduction board of a communication vehicle. Background Art

[0002] Communication vehicles are special vehicles equipped with communication equipment to ensure communication and are used for mobile communications. They are usually divided into emergency integrated communication vehicles, network management vehicles, program-controlled telephone vehicles, adaptive frequency-hopping radio vehicles, digital spread spectrum relay vehicles, scattering communication vehicles, satellite communication vehicles, optical cable connection vehicles, cable retracting vehicles, and communication power supply vehicles.

[0003] At present, the emergency integrated communication vehicles used by communication companies and troops often need to be stationed in remote areas or areas with harsh climates. Therefore, the communication vehicles need to be equipped with communication equipment to adapt to more complex climate conditions. The vehicle-mounted power wall box is an external window for all communication equipment and an indispensable part of the emergency integrated communication vehicles used by communication companies and troops. At present, the signal port of the communication vehicle or electronic square cabin is only configured as a "connector or threading hole", which is too simple. The function is single, lacks safety protection, has no electromagnetic compatibility, and is prone to electromagnetic interference. Some simple power wall boxes and signal introduction board electromagnetic protection devices with electromagnetic compatibility have also appeared on the market. However, since it is a whole, when one part of it is damaged, other parts also indirectly fail, which seriously affects the safety of the emergency integrated communication vehicle. Summary of the invention

[0004] The purpose of the present invention is to provide an electromagnetic protection device for a power wall box and a signal introduction board of a communication vehicle to overcome the deficiencies of the above-mentioned prior art.

[0005] The technical solution of the present invention is implemented as follows: the protection device comprises: a shielding box body, a plurality of electromagnetic protection sub-boxes arranged in the shielding box body, a first sub-panel and a second sub-panel arranged in the electromagnetic protection sub-boxes, wherein the first sub-panel and the second sub-panel are connected via a circuit connection line;

[0006] A box door is provided at one end of the shielding box body, a door panel is provided on one side of the box door, at least three groups of vertical partition wall panels and at least four groups of horizontal partition wall panels are provided inside the shielding box body, multiple groups of slideways are horizontally provided on two adjacent groups of vertical partition wall panels along the box door direction of the shielding box body, multiple electromagnetic protection sub-boxes are respectively slidably connected to the slideways at corresponding positions, a wiring sub-box body is provided at the end opposite to the box door of the shielding box body, the shielding box body and the wiring sub-box body are separated by a wiring board, and multiple first wire threading holes and cable routing binding buckles are provided on the wiring board;

[0007] Slide grooves are arranged on the side walls of both sides of the electromagnetic protection sub-box, and the slide grooves are slidably connected to the slideways. A second threading hole is arranged at one end of the electromagnetic protection sub-box away from the box door of the shielding box body, and the second threading hole is used to pass the wire passing through the first threading hole. A pad made of elastic material is arranged on the bottom surface of the electromagnetic protection sub-box, and the first sub-panel and the second sub-panel are respectively fixedly connected to the corresponding pads;

[0008] The first sub-panel is provided with an in-vehicle optical port, an in-vehicle coaxial signal interface, an in-vehicle data interface, an in-vehicle two-wire signal interface, fixing bolts, and an in-power supply interface;

[0009] The second sub-panel is provided with an external vehicle optical port, an external vehicle network port, an external vehicle two-wire signal interface, an external vehicle data interface, an external vehicle coaxial signal interface, and an external power supply interface.

[0010] The advantages and positive effects of the present invention are:

[0011] 1. The present invention adopts a split setting for the shielding box, so the external devices of the power protection wall box and the signal introduction device are safer during the connection process, and there is no need to worry about other parts of the signal introduction device being damaged due to environmental reasons. In addition, by arranging cable routing and binding buckles on the main shielding box body and the auxiliary shielding box body to route the cables in the shielding box, the cables in the main shielding box body and the auxiliary shielding box body are less likely to become loose due to the vibration of the communication vehicle during driving.

[0012] 2. The multiple electromagnetic protection sub-boxes of the present invention can be pulled out separately in the shielding box body according to the requirements of the operator to ensure that the electromagnetic radiation to which the operator is exposed during operation is reduced to the minimum, and when an accident occurs, all panels will not be damaged due to damage to one panel. In addition, a pad with an elastic structure is provided in the electromagnetic protection sub-box to solve the problem of vibration damage to the panel when the communication vehicle is driving on an unstable road section.
