Abstract
The utility model provides an interface module with filtering function, which belongs to the filtering technical field of the electronic products, structurally comprising an aviation plug interface board. Aviation plug interfaces with filtering function are arranged on the aviation plug interface board. A connecting line of the aviation plug interfaces is connected with a filtering array board. The filtering array board is fixed with the aviation plug interface board by a screw. Comparing with the prior art, the interface module with filtering function has the advantages of reasonable design, simple structure and convenient use, which can adapt to the complicated field environment including high-low temperature, wet heat, electromagnetic environment, shock, impact and the like, and the special vehicle in bad environment.
Description
Technical field
The utility model relates to the technical field of filtering of electronic product, a kind of specifically interface module with filter function.
Background technology
To from the audio frequency of computer motherboard, video, PS/2, network, serial paralled interface, when signals such as USB, VGA carry out filtering, current computer in most cases is to adopt specific Design of Filter.Above-mentioned signal at first is transported to filter by incoming line, behind filter filtering, by output line the signal of handling well is exported again.Above-mentioned occupation mode can be introduced a lot of lines unavoidably in the signal input.Circuit intersects, and not only seems in disorder in appearance, and can cause signal in the wire harness to produce mutually and crosstalk, and loses the meaning of filtering.Use special filter, inconvenience is installed, bring certain design pressure for the structure personnel.Simultaneously existing computer proposes high requirement to adapting to complicated wild environments such as high low temperature, damp and hot, electromagnetic environment, vibrations, impact, and traditional filter then can't well be applied in the computer of working under the adverse circumstances at present.Therefore, a kind of new mode filter that is applied to the abominable special environment of environment of design is very important.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, a kind of anti-vibrating and impact, easy installation and removal is provided, has the interface module of filter function.
The technical solution of the utility model realizes in the following manner, this a kind of interface module with filter function, its structure comprises the air plug interface board, described air plug interface board is provided with the air plug interface with filter function, the line of air plug interface all is connected on the filter array plate, and described filter array plate fixes by screw and air plug interface board.
Described air plug interface comprises audio interface, video interface, PS/2 interface, network interface, serial line interface, parallel interface, USB interface, VGA interface.
Described air plug interface board outer surface is provided with handle.
The beneficial effect that the utility model is compared with prior art produced is:
A kind of interface module with filter function of the present utility model can provide filtering signal at the electronic system intermodule, and the more traditional filtering mode of cost decreases, and meets the EMC requirement again, and wire harness is crosstalked when reducing filtering, avoids interference the generation of signal; Wherein testing through strict on the filtration module has more reliability; The bulk strength of this filtration module and anti-vibrating and impact ability are greatly improved by its modularized design, and the maintenance and repair needs are satisfied in easy installation and removal simultaneously.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is user mode figure of the present utility model.
Mark in the accompanying drawing is represented respectively:
1, filter array plate, 2, the air plug interface board, 3, the air plug interface, 4, handle, 5, cabinet.
Embodiment
Below in conjunction with accompanying drawing a kind of interface module with filter function of the present utility model is done following detailed description the in detail.
As accompanying drawing 1, shown in Figure 2, this a kind of interface module with filter function, its structure is made up of air plug interface board 2, filter array plate 1 etc., described air plug interface board 2 is provided with the air plug interface 3 with filter function, and these air plug interfaces 3 comprise audio interface, video interface, PS/2 interface, network interface, serial line interface, parallel interface, USB interface, VGA interface; The line of air plug interface 3 all is connected on the filter array plate 1, and described filter array plate 1 fixes by screw and air plug interface board 2.
Described air plug interface board 2 outer surfaces are provided with handle 4.
Design principle of the present utility model is: based on based on computer desired signal such as audio frequency, video, PS/2, network, serial ports, parallel port, USB, VGA signal etc., at first signal is classified, then each signal is carried out filtering.Wherein, can be input in the air plug with filter function by keyset, by air plug filtering and output by the signal of air plug processing.Must carry out the signal of Filtering Processing by filter, be input to special-purpose filter and carry out filtering and output.
The utility model adopts modularized design, simultaneously all air plug interfaces 3 are designed on an air plug interface board 2, the bulk strength and the anti-vibrating and impact ability of filtration module have been improved, make things convenient for installing/dismounting, satisfy the maintenance and repair needs, air plug interface 3 has been done Filtering Processing, makes the electromagnetic compatibility characteristic of machine reasonablely to be met; And the line integral body of air plug interface 3 back on the air plug interface board 2 is made the form of filter array plate 1, made things convenient for like this filter array plate 1 directly has been plugged on computer cabinet 5 interior backboards by its connector, can improve the electromagnetic compatibility effect of complete machine, can remove all lines of machine intimate again, improved the degree of modularity of complete machine, inner neat appearance, and realized machine moduleization, be convenient to later maintenance.
