Description
[technical field]
The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector that can effectively prevent cross-talk.
[background technology]
For the computer and perimeter electronic equipment,, make the signal amount of required transmission in the whole system increase greatly in recent years gradually to functional diversities and intelligent development thereupon; Yet in the case, the outward appearance of computer and correlated parts and part but trend towards lightweight, microminiaturized direction develops.In order to cooperate the working transmission that electronic product increases greatly and the dual growth requirement of volume microminiaturization simultaneously, it is many and the less high density electrical connector of volume arises at the historic moment to be applied in numbers of terminals in the high-frequency transmission, and is applied to more and more widely in computer and the peripheral electronic equipment thereof.
Yet for the high density electrical connector in being applied in high-frequency transmission, the difference team that positive negative signal is transmitted in general employing respectively comes transmission signals, its numbers of terminals is many, densely distributed, thereby when the high-frequency electronic signal passes through, adjacent terminal is to very easily producing the phenomenon that interaction crosstalk disturbs, and causes the signal transmission unstable and influence the normal operation of electronic equipment.So high density electrical connector can take variety of way to prevent cross-talk phenomenon in the signals transmission usually.
Present common a kind of mode of eliminating high density electrical connector cross-talk phenomenon, as announce in the United States Patent (USP) the 6th on August 31st, 2004,783, shown in No. 400, the signal terminal of the electric connector that it disclosed is contained in insulating body in pairs, adjacent two signal terminals between be provided with an earth terminal or shield terminal with prevent the adjacent signals terminal to cross-talk.
Only to arrange be two row to terminal in the above-mentioned electric connector, and when terminal is arranged into multirow, when adopting aforesaid way to arrange terminal, the number of terminal is more.In the manufacture process of electric connector, when adopting inserting mode that terminal group is filled to insulating body, assembling process will be comparatively loaded down with trivial details.In addition, when terminal was arranged into multirow, the shield effectiveness of earth terminal or shield terminal was also not ideal enough.
Therefore, necessaryly provide a kind of electric connector, can comparatively effectively prevent cross-talk and can make the manufacturing of electric connector simple and easy.
[utility model content]
The purpose of this utility model is to provide a kind of and can comparatively effectively prevents cross-talk and make comparatively easy electric connector.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: the definition of the utility model electric connector have by after the butt joint direction of extending forward, it comprises: insulating body; Several signal terminals, be contained in the insulating body, it comprises the connecting portion that is used to be electrically connected to circuit board that contact arm that main part, autonomous body extend forward and autonomous body extend, described contact arm extends along the butt joint direction, and described signal terminal comprises that contact arm is arranged in first row signal terminal of first row and the second row signal terminal that contact arm is arranged in second row; Described electric connector is provided with ground plate, described ground plate comprises that slice plate body, two arms that extend along the butt joint direction from plate body reach the ground connection connecting portion that is used to be connected to circuit board that extends from plate body, described two arms are arranged in same delegation with the contact arm of the first row signal terminal and the contact arm of the second row signal terminal respectively, and described plate body is then between the main part of adjacent two signal terminals of the first row signal terminal and between the main part of adjacent two signal terminals of the second corresponding row signal terminal.
Compared with prior art, the utlity model has following beneficial effect: the ground plate of isolating adjacent two signal terminals in the first row signal terminal (or signal terminal to) in the utility model can also be isolated and aforementioned adjacent two signal terminals two adjacent signal terminals in the second corresponding row signal terminal simultaneously, and promptly described ground plate can be isolated corresponding several to two adjacent signal terminals (or signal terminal to) simultaneously.This ground plate promptly is equivalent to the earth terminal of several independent configurations, but it prevents that the effect of cross-talk but is better than the earth terminal of several independent configurations; And that the manufacturing of ground plate and ground plate are plugged in the insulating body is all comparatively easy, thereby makes the manufacture process of electric connector simplify.
