Description
Technical field
The invention discloses a kind of shielding construction and its application, especially a kind of data-interface terminal shielding structure and its answer
With.
Background technique
Shield technology is one of a kind of highly important means for realizing Electro Magnetic Compatibility and most common means.
At present in display product scope, circuit board and connecting line are usually subjected to shielding processing, to solve the problems, such as Electromagnetic Launching, but
Shielding processing is fairly simple at terminal plug receptacle, such as USB interface only passes through kalamein and signal wire metal dots connect to form screen
It covers, becomes the weakness shielded in entire signal path system, this simple connection type, which has, overlaps insecure hidden danger, holds
The problem of easily causing radiation-emitting to be unsatisfactory for standard.For such issues that, mesh has two class settling modes, first is that there is more special knot
The signaling interface of structure solves the problems, such as this, because structure is very special, needs to do major change to the structure of product and needs spy
Different wire rod cooperation could use, and it is very high to will result in cost in this way, therefore only limitation use cannot push away on a large scale on specific products
It is wide to use；Another is had an impact in this way to transmission signal quality, Er Qiecheng by the way that filter is added in terminal plug receptacle
This is also very high, and use is relatively more limited.
Summary of the invention
In order to solve deficiency in the prior art, the purpose of the present invention is to provide a kind of structures simple, high universalizable, easily
It produces, be easily installed and data-interface terminal shielding structure and its application fixed, low in cost, that promote shield effectiveness.
To achieve the above object, the invention adopts the following technical scheme:
Data-interface terminal shielding structure, including metallic shield set, the metallic shield set are fixed on terminal interface periphery,
There are gap between metallic shield set and terminal interface, the gap is inserted into for the connector sleeve of signal wire terminal interface, connector sleeve
After insertion, in the spliced eye in signal wire stitch insertion terminal interface in connector sleeve, the end face of metallic shield set is resisted against letter
In number line terminals plane, and connector sleeve is fully wrapped around.
The metallic shield covers one end and is equipped with mounting base, and fixation hole is set in the mounting base, and fixation hole will be golden by screw
Belong to housing to be fixed on terminal.
At least two marks of break are set on the metallic shield set connection extreme direction.
The metallic shield is arranged at least one inside bending, and the connector sleeve surface correspondence sets matched recessed with bending
Fall into slot.
The data-interface terminal shielding structure is applied to electronic product data Interface Terminal.
The invention adopts the above technical scheme, on the basis of existing technology, adds a metal in terminal interface periphery
Housing, haves no need to change that existing terminal structure is i.e. mountable, and metallic shield set is fully wrapped around by the connector sleeve after insertion, tool
There is good shield effectiveness；Mark of break is set on metallic shield set, facilitates that connector sleeve is preferably inserted into metallic shield set and terminal connects
Gap between mouthful, bending and recessed groove make metallic shield set and the better clamping of connector sleeve.The configuration of the present invention is simple has
High universalizable, it is easy to produce, be easily installed and fixed, low in cost, shield effectiveness is excellent, design is rationally, practical.
Detailed description of the invention
The present invention is described in further details below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural schematic diagram of metallic shield of the present invention set；
Fig. 2 is two-terminal and the decomposition diagram that metallic shield covers；
Fig. 3 is two-terminal and the cooperation schematic diagram that metallic shield covers；
Fig. 4 is schematic cross-sectional view of the Fig. 3 along the face A-A '；
Fig. 5 is the signal wire terminal structure schematic diagram with recessed groove.
Specific embodiment
As shown in one of Fig. 1-5, data-interface terminal shielding structure, including metallic shield set 2, the metallic shield set 2
It is fixed on 81 periphery of terminal interface, there are gaps between metallic shield set 2 and terminal interface 81, and the gap is for signal line terminals
The connector sleeve 71 of interface is inserted into, and after connector sleeve 71 is inserted into, the signal wire stitch 72 in connector sleeve 71 is inserted into terminal interface 81
In spliced eye 82, the end face 9 of metallic shield set 2 is resisted against in 7 plane 73 of signal line terminals, and connector sleeve 71 is fully wrapped around.
The metallic shield covers 2 one end and is equipped with mounting base 1, sets fixation hole 5 in the mounting base 1, fixation hole 5 passes through screw
6 are fixed on metallic shield set 2 on terminal 8.
At least two marks of break 3 are set on the 2 connection extreme direction of metallic shield set.
The metallic shield set 2 sets at least one inside bending 4, and 71 surface of the connector sleeve correspondence is set and bending 4
The recessed groove 74 matched.
The data-interface terminal shielding structure is applied to electronic product data Interface Terminal.
Electromagnetic wave is at the interface of different propagation mediums, and due to the mutation of wave impedance, electromagnetic wave can reflect.In addition,
In transmission medium, such as inside metal material, electromagnetic wave can decay, so metallic shield set of the invention can effectively solve
Electromagnetic Launching problem.
