Description

Can eliminate the electric connector of electromagnetic interference
Technical field
The utility model relates to a kind of electric connector of eliminating electromagnetic interference, particularly a kind of electric connector that can effectively intercept the above Electromagnetic Interference of specific wavelength.
Background technology
Because the part in electronic motor instrument or the device is when running; a kind of electromagnetic wave noise that regular meeting produces; and this electromagnetic wave noise may influence other peripheral devices via radiation or conduction pattern; and cause the undesired or distortion of these other peripheral devices; this is so-called electromagnetic interference (ElectromagneticInterfering is called for short an EMI) phenomenon.
And today, very general computer promptly was an electronic installation of being made up of many electronic components, so its chance that electromagnetic interference phenomenon takes place is high, for example at keyboard electric connector place, slide-mouse electric connector place or network circuit connector place etc.
For this reason, manufacturers research and develop the electric connector of eliminating electromagnetic interference invariably with all strength.With the existing keyboard electric connector of eliminating electromagnetic interference is example, see also shown in Figure 5, it comprises a body 50, a metal shell 60 and a ground strip 70, wherein the leading flank of this body 50 is provided with a plurality of spliced eyes 51, for a plurality of conducting terminal (not shown) insertions and the electrical connection with it of an electric connector (not shown); The bottom side of this body is provided with a plurality of lead foots 52 again, and power supply is connected on the computer motherboard (not shown); This metal shell 60 coats and is located at outside this body 50 again, and in spliced eye 51 places that should body 50 are formed with an opening 61; And this ground strip 70 is a reverse U shape, and it has an even surface, and the oblique outside of being located at body 50 leading flanks, and contacts with metal shell 60.
See also Fig. 6, shown in Figure 7 again, in the time of in above-mentioned electric connector is located at a computer chassis 80, because a plurality of spliced eyes 51 of electric connector expose to outside this computer chassis 80, so electric connector is promptly quite approaching with computer chassis 80 inwalls, and makes the ground strip 70 of electric connector can be resisted against on computer chassis 80 inwalls; Because this computer chassis 80 promptly can be used as a ground plane usually, therefore when this electric connector connects an Electric plug with shutter, the path that this metal shell 60 and this ground strip 70 promptly can be used as a ground connection, and the electromagnetic wave noise is derived, thereby reach the purpose of eliminating electromagnetic interference.
Only when this computer chassis 80 compresses this ground strip 70, owing to having an even surface of this ground strip 70, and the oblique again outside of being located at body 50 leading flanks, so this ground strip 70 only can contact (as shown in Figure 7) with computer chassis 80 with single line segment usually; Though the design of ground strip 70 can effectively intercept most electromagnetic wave, only because its still non-body 50 that coats fully, so still have the space between ground strip 70 and the body 50, thus can't accomplish that 100% intercepts Electromagnetic Interference, thereby can't effectively intercept the above Electromagnetic Interference of specific wavelength.
This shows that the above-mentioned existing electric connector of eliminating electromagnetic interference obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of electric connector of the novel electromagnetic interference eliminated, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Because the defective that the above-mentioned existing electric connector of eliminating electromagnetic interference exists, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of electric connector of the novel electromagnetic interference eliminated, can improve the general existing electric connector of eliminating electromagnetic interference, make it have more practicality.Through constantly research, design, and, create the utility model that has practical value finally through after studying sample and improvement repeatedly.
Summary of the invention
Main purpose of the present utility model is, overcome the defective that the existing electric connector of eliminating electromagnetic interference exists, and a kind of electric connector of the novel electromagnetic interference eliminated is provided, technical problem to be solved is to make it can effectively intercept the above Electromagnetic Interference of specific wavelength.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.Electric connector according to the electromagnetic interference eliminated that the utility model proposes comprises:
One body which is provided with a plurality of spliced eyes and a plurality of lead foot, and wherein this spliced eye plugs for a peripheral device plug, and this lead foot then is arranged on the motherboard for this electric connector is electrically connected;
One metal shell coats this body, and is formed with an opening in a plurality of spliced eyes place of corresponding body; And
One ground strip is a reverse U shape, and its surface is bent into wavyly, and the two ends of this ground strip are connected with this metal shell again, and constitutes an angle with a side that metal shell is formed with opening.
The purpose of this utility model and solve its technical problem and can also be able to be further achieved by the following technical measures.
The aforesaid electric connector of eliminating electromagnetic interference, the two ends of wherein said ground strip upwards are formed with a hook part respectively, penetrate with the bottom side from this metal shell and are fixed in this metal shell inwall.
By technique scheme, the electric connector that the utility model can be eliminated electromagnetic interference has following advantage and beneficial effect at least:
Utilize above-mentioned technological means, can utilize the bending external form of this ground strip and the inwall multiple spot or polygon contact of this computer chassis, contact part with the Electromagnetic Interference more than the obstruct specific wavelength, and then guarantee the effect of the anti-electromagnetic interference of this electric connector by increasing.
In sum, the utlity model has above-mentioned plurality of advantages and practical value, no matter it all has bigger improvement on product structure or function, obvious improvement is arranged technically, and produced handy and practical effect, and the more existing electric connector of eliminating electromagnetic interference has the outstanding effect of enhancement, thus be suitable for practicality more, and have the extensive value of industry, really be a new and innovative, progressive, practical new design.
