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 double-deck 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, its numbers of terminals is many, densely distributed, close together between two two-terminal, thereby when the high-frequency electronic signal passes through, very easily produce the phenomenon that interaction crosstalk disturbs between adjacent terminal, cause 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.
Common a kind of mode of eliminating the cross-talk phenomenon is every a signal terminal earth terminal to be installed promptly in high density electrical connector at present, as announce in the United States Patent (USP) the 6th on April 1st, 2003,540, No. 559 and announce in the United States Patent (USP) the 6th on February 26th, 2002,350, No. 134, in the electric connector that they disclose, terminal lists and has all adopted the arrangement mode of " any two adjacent signals terminals to be provided with earth terminal " in each row and each, wherein said a pair of signal terminal symmetrical configuration and in delegation parallel arranged, earth terminal has a flat body portion (or whole for flat), the transverse width of described earth terminal corresponding to the horizontal span of a pair of signal terminal with at row to covering two pairs of adjacent earth terminals.
Yet, adopt aforesaid way no doubt can prevent to be positioned at interference between the signal terminal of same row preferably by the shielding of flat earth terminal, yet because the distribution character of magnetic field and electric field, the earth terminal of flat can not prevent well with the interference between the signal terminal of delegation.
Consider from another angle, the transverse width of earth terminal is corresponding to the horizontal span of a pair of signal terminal in this electric connector, the position of arranging terminal on the electric connector is not to be used for the earth terminal of transmission signals to occupy in a large number, and this does not obviously meet the double-deck development trend of computer and high working transmission of electronic component and volume microminiaturization.
The mode of cross-talk when also having a kind of anti-stop signal to transmit in addition, as announce in shown in No. the 99113855th, the Chinese patent on May 5th, 2004, but the electric connector that it disclosed is the metallic conductor the side setting ground connection of terminal accommodating passage, and the minimum distance perseverance that makes arbitrary conducting terminal and its side metallic conductor is less than this terminal and the spacing of terminals of adjacent arbitrarily, makes by changing electric field around the terminal and magnetic field that the signal coupling efficiency reduces to reduce cross-talk between terminal.Yet this kind mode only can reduce cross-talk to a certain extent, for the cross-talk between the terminal of metallic conductor homonymy to improve effect unsatisfactory.
Therefore, necessaryly provide a kind of electric connector, can prevent effectively that cross-talk from can make the overall structure of electric connector comparatively compact again.
[utility model content]
The purpose of this utility model is to provide a kind of cross-talk that can effectively prevent can make the comparatively compact electric connector of overall structure again.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: the utility model electric connector has the butt joint chamber that is used to accommodate the butt joint electric connector, it comprises: insulating body, and it has the lengthwise hyoplastron that protrudes at least two almost parallels in the butt joint chamber; Several signal terminals, it in a row extends respectively on the two lengthwise sides of each hyoplastron; Be embedded with at least one in each hyoplastron at the first ground connection lamellar body between two row of signal terminals on this hyoplastron; At least one second ground connection lamellar body is embedded in the insulating body and between adjacent two row of signal terminals on the different hyoplastrons.
Compared with prior art, the utlity model has following beneficial effect: platy structure that earth terminal adopts and terminal arranging on the whole can reduce preferably the adjacent signals terminal to interference, in addition, ground strip is contained in the described insulating body, has effectively utilized the overall space of electric connector.
