Description

The Power Filter Lightningproof Board that a kind of structure novel is easily installed
Technical field
The utility model is related to a kind of Power Filter Lightningproof Board, it can be widely applied to that internal electromagnetic compatible environment is complicated, space is narrow In small mobile system, equipment etc., to shield and inhibit the transmitting of electromagnetic interference signal and system is protected to be damaged from lightning surge Evil.
Background technology
With the development of Airplane Flight Control System ', small size, multipurpose are just becoming design mainstream.This design philosophy requirement exists It is integrated in small size cabinet comprising various functions such as power supply power supply, function control (including various buses) or even motor controls.This The method of various height frequency signal integrations together proposes the EMC Design of system very high requirement by kind.If according to More solito wires design will certainly cause the mutual crosstalk of interference signal of various different frequencies in system, cause distorted signals very To distortion, malfunction even can be generated if serious.Meanwhile with RTCA/DO-160F《Airborne equipment environmental condition and experiment Method》It is universal, the requirement for meeting wherein " lightning induction transient state susceptibility " index is also very difficult.Therefore, it is necessary to change to pass The EMC Design thinking of " the foot pain doctor foot for the treatment of the head when the head aches " of system, is improved rectification means from source, and use for reference and be somebody's turn to do Thinking adds in the lightning protection component of suitable parameters preferably to be protected to system in filter circuit.
Invention content
The purpose of this utility model is to provide a kind of structure novel, has excellent performance, and meets mounting condition in complicated cabinet, easily It is installed and used in client, and can effectively promote the Electro Magnetic Compatibility of mobile system and the filter band of lightning protection properties.
In order to achieve the above object, the technical solution of the utility model is easily installed anti-there is provided a kind of structure novel Thunder filter band, which is characterized in that the device including interface board and for placing different types of component and out connector Plate, there are input connector holes, input connector on interface board to be mounted on by input connector hole on interface board, interface board with It is connected between device board by flexible PCB transition.
Preferably, the component being installed on the device board is covered with plastic shell.
Preferably, it is equipped with filter band mounting hole in the bottom of the plastic shell.
The utility model selects filtering and the lightning protection component of suitable parameters, system under test (SUT) can be made to meet RTCA/DO-160F 《Airborne equipment environmental condition and test method》In the 21st part:RF energy emits chapters and sections and the 22nd part:Lightning induction wink The requirement of state susceptibility.
The utility model has the following advantages that:
(1) each signal wire is clean and tidy clear with power cord filter circuit arrangement, and experiment is facilitated to rectify and improve.If without flexible PCB This medium, connection cabling certainly will be disorderly and unsystematic, disorderly such as straw, further increases the possibility of mutual Space Coupling, is not achieved Prevent the requirement of electromagnetic interference.
(2) using flexible PCB, electromagnetic compatibility effect is more preferable.For the angle of control electromagnetic compatibility, filter circuit to electricity The shorter thread guide path the better at source interface.After flexible PCB, the path of conventional wire cable " two right-angle sides of triangle " can be contracted The short length for " bevel edge ".
(3) filter circuit installation is no longer limited by space.Previous filter circuit and interface are " Hard link ", size Slightly point comes in and goes out, that is, faces the awkward situation that can not be installed.After adopting new technology, no longer there are the inappropriate problems of bulk.
(4) it is more suitable for filtering the ground connection of plate and lightning protection component.It is certain in circuit in order to achieve the purpose that filtering and lightning protection Device needs to carry out grounding.After the utility model, such all device are used uniformly earthing screw and carry out at ground connection Reason, that is, shorten grounding path, and improve the aesthetics of product.
Description of the drawings
Fig. 1 is a kind of front view of Power Filter Lightningproof Board provided by the utility model;
Fig. 2 is the schematic internal view of the utility model;
Fig. 3 is the front view of the utility model;
Fig. 4 is the schematic bottom view of the utility model;
Fig. 5 is the stereoscopic schematic diagram of the utility model.
Specific embodiment
To be clearer and more comprehensible the utility model, hereby with preferred embodiment, and attached drawing is coordinated to be described in detail below.
With reference to Fig. 1 to Fig. 5, the Power Filter Lightningproof Board that a kind of structure novel provided by the utility model is easily installed includes interface Plate 1, flexible PCB 3, device board 4, plastic shell 2 and leading-out terminal 6.
It, can will be different according to system actual requirement by input connector hole 7 there are input connector hole 7 on interface board 1 The input connector of type is mounted on interface board 1, then is connected with docking power-feed connector.
" bridge " of the flexible PCB 3 for connecting interface plate 1 and device board 4, flexible PCB 3 is foldable stretchable, can be according to machine Case actual size adjusts the relative position of interface board 1 and device board 4, is suitble to install and use in different size cabinets.
Different types of component 8 is placed on device board 4, these components 8 can make system meet electromagnetic compatibility and lightning protection Hit requirement.Leading-out terminal 6 is also mounted on device board 4, ensures that the custom system with rear end is reliably connected.
Plastic shell 2 is fixed on by click on fashion on device board 4, and component 8 is physically separated with external environment, It can prevent insulating properties of the component because damaging and improving product after the reasons such as shock and vibration and the collision of cabinet wall.
Filter band mounting hole 5 is used to filter band provided by the utility model being fixed to chassis earth column, and complete to be grounded.
During work, the electromagnetic interference signal in power grid is entered provided by the utility model by power cord and input connector Filter band after filtered plate inhibits attenuation, has entered the electromagnetic interference signal level energy of back-end system by out connector It is quite weak, the normal work with interference system is not interfered with, plays the role of safeguard protection.Equally, when the systems are operating normally The electromagnetic interference signal of generation, via output connections device enter filter band, by filter band inhibit attenuation after, through input connector into The electromagnetic interference signal level energy entered in power grid is quite weak, does not interfere with and pollutes power grid, plays protection and purifying electric The effect of net.
