[embodiment]
Refer to shown in Fig. 1 to Fig. 5, the present invention has disclosed a kind of electric connector 100 for signal high-speed transfer, it comprises some terminal assemblies 1 and insulation butt joint body 4, and these terminal assemblies 1 are arranged in parallel each other closely, and the termination contact portion 31 of its front end protrudes out the mating surface 202 of terminal assemblies.4 of butt joint bodies of insulation are provided with the conduit 41 that runs through front/rear end.The contact site 31 of these terminal assemblies enters conduit 41, so, forms the integral frame of the present embodiment electric connector 100.
Refer to shown in Fig. 2 to Fig. 4, described each terminal assemblies 1 is comprised of three parts, and it comprises the first terminal template 11, the second terminal template 12 and a barricade 13.The structure of the first terminal template 11 and the second terminal template 12 is similar, includes insulator 2 and metallic conduction terminal 3.Insulator 2 is platy structure, the L-type structure that conducting terminal 3 is sheet, several conducting terminals are arranged in parallel and are embedded in insulator 2, and an exposed side 201 at insulator, one side of conducting terminal, in most preferred embodiment, conducting terminal is shaped in insulator.The contact site 31 of the front end of conducting terminal protrudes out an end face (being mating surface 202) of insulator, the welding foot 32 of conducting terminal protrude out insulator another with mating surface contiguous and vertical end face (being installed surface 203), be connected in contact site 31 and be close in the side 201 of insulator with the connecting portion 30 of welding foot 32.Welding foot 33 punchings are provided with through hole 321, and when welded and installed pin is not to circuit board (indicating) like this, scolding tin can enter in through hole 321, and welding foot 32 can be stably combined with circuit board.The another side of opposite flank 201 is provided with some grooves 21 in corresponding connection parts position, contribute to improve electric property.Barricade 13 is laminated structure setting, and the shape of its shape and conducting terminal corresponds to each other, and is held between the first terminal template 11 and the second terminal template 12, in order to reduce the interference between conducting terminal 3.
The conducting terminal 3 of each terminal template consists of one group of terminal being parallel in same plane, it comprises signal terminal 33 and earth terminal 34, signal terminal 33 and earth terminal 34 are intervally arranged in same plane, and wherein signal terminal is used for signal transmission earth terminal for ground connection.Introduce the concrete structure of each terminal below.Each signal terminal comprises by two sheet metal or bonding jumper Difference signal pairs that partner independently, it comprises contact jaw 331, welding foot 332 and connecting portion 330, contact jaw is forked, the free terminal of a contact jaw is bent to form two elastic contact parts 3311, elastic force that can the sub-Elastic Contact in providing end.The connecting portion 342 that earth terminal 34 comprises welding foot 340 and is connected with welding foot, does not have the contact site of similar signal terminal, and the wider width of earth terminal is almost identical with a Difference signal pair.Each terminal template comprises four pairs of signal terminals and an earth terminal between adjacent signals terminal, and each Difference signal pair is spaced apart.
Please pay special attention to, the conducting terminal 3a of the first terminal template is similar with the conducting terminal 3b structure of the second terminal template, but signal terminal follows the arrangement mode of earth terminal to be staggered.The conducting terminal 3a of the first terminal template away from weld part 32 be earth terminal 34, be next only signal terminal, then alternative arrangement.And the conducting terminal 3b of the second terminal module away from weld part 32 be signal terminal 33, be next only earth terminal 34, then alternative arrangement.So, in the direction perpendicular to two-terminal template, the signal terminal of the first terminal template is the earth terminal of alignment the second terminal template just, and just the align earth terminal of the first terminal template of the signal terminal of the second terminal template, can reach the shielding action making progress the party.
Barricade 13 has the first relative wall 13a and the second wall 13b, it comprises contact site 131 and connecting portion 132, connecting portion is tabular, the connecting portion of all conducting terminals 3 of its shape heel end subtemplate is corresponding, but do not disconnect, contact site 131 extends out and respectively alternately to two lateral bucklings, is two row's shapes from the front end of connecting portion, between the Difference signal pair of the lucky signal terminal in each terminal template of every row's contact site 131, shown in Fig. 2.Barricade is arranged between two-terminal module, because it is not provided with welding foot, also needs the structure that barricade is connected with earth terminal is set, and below in conjunction with Fig. 5, illustrates structure.
Shown in Fig. 4, Fig. 5, on the first wall 13a of barricade 13, utilize the ductility of metal to a side blow, to extrude fin 134 respectively, in relative another side, form chase 135, because barricade is not established welding foot, fin 134 is connected on the connecting portion 342 of earth terminal 34, with connecting portion 342Wei intermediary, barricade 13 can be used the effect (be face contact between fin and earth terminal, earthing effect is better) that the welding foot 340 of earth terminal 34 is grounded indirectly.Because the conducting terminal 3a of the first terminal template is upper and lower being staggered with the earth terminal in the conducting terminal 3b of the second terminal template, therefore the stamping position of first, second wall staggers, interlaced with each other being intervally arranged of fin 134a, 134b on first, second wall 13a, 13b, the fin on final barricade two walls all can abut on the earth terminal in first, second terminal template realizes bonding.Please note, because fin 134 and chase 135 are intervally arranged, and earth terminal 34 and signal terminal 33 are also for being intervally arranged, like this in the time of fin and earth terminal butt, chase can form encirclement to signal terminal, and (chase makes signal terminal broaden in the distance perpendicular in shield direction, and it is wide compared with signal terminal that the width of chase arranges), barricade 13 not only can be separated the signal terminal in two-terminal template like this, for the signal terminal in same piece terminal template, be separated and come equally, make shield effectiveness more outstanding, crosstalking between signal terminal can be reduced to minimum.Barricade of the present invention is for fitting in two-terminal template, reduced the spacing (having reduced equally the distance between the first terminal template and the second terminal template) between conducting terminal 3a and conducting terminal 3b, can produce the electric connector of small size like this, meet the development trend of current electric connector miniaturization.
In sum, the present invention surrounds on it arranges path by 135 pairs of signal terminals 33 of chase of barricade, 134 of fins are connected to earth terminal 34 and arrange on path at it, thereby can effectively reduce the signal cross-talk between signal terminal by separation signals terminal when setting can be grounded conducting terminal 3 effectively like this.These are only preferred embodiment of the present invention, the not above embodiment of the present invention is restriction, and the people who understands this case design main points is in every case done equivalent change with this, all should contain in this case claim.
