[0014] 每一端子模板的导电端子3由一组平行排列于同一平面内的端子构成,其包括信号端子33及接地端子34,信号端子33和接地端子34间隔排布于同一平面内,其中信号端子用于传输信号而接地端子则用于接地。 [0014] The conductive terminal of each terminal modules 3 are arranged in parallel to the terminal by a set of configuration in the same plane, which includes a signal terminal 33 and the ground terminal 34, signal terminals 33 and ground terminals 34 are arranged spaced in the same plane, wherein a signal terminal for transmitting a signal ground terminal is used for grounding. 下面介绍各个端子的具体结构。 The following describes a specific configuration of each terminal. 每一信号端子包括由两个独立的金属片或者金属条组成一对差分信号对,其包括接触端331、焊接脚332及连接部330,接触端呈分叉状,一个接触端的自由末端弯折形成两个弹性接触部3311,可提供端子弹性接触的弹性力。 Each signal terminal comprises two separate metal sheets or metal strips of a pair of differential signal pair comprising a contact end 331, soldering portions 332 and 330 are connected, as a bifurcated contact end, a free end of the contact end is bent forming two resilient contact portions 3311 may provide an elastic force of the elastic contact terminals. 接地端子34包括焊接脚340及与焊接脚相连的连接部342,不具有类似信号端子的接触部,接地端子的宽度较宽,跟一个差分信号对差不多相同。 34 comprises a ground terminal pin 340 and the solder connection portion 342 connected to the welding pin, having no contact with similar portions of the signal terminals, the wider the width of the ground terminal, a differential signal pair with almost the same. 每一端子模板包括四对信号端子及位于相邻信号端子之间的一个接地端子,将每一差分信号对间隔开。 Each terminal module includes four pairs of signal terminals and one ground terminal located between the adjacent signal terminals of each differential signal pair of spaced-apart.

[0015] 请特别注意,第一端子模板的导电端子3a跟第二端子模板的导电端子3b结构类似,但是信号端子跟接地端子的排列方式呈交错状。 [0015] Note in particular that the first conductive terminal 3a of the terminal modules with similar structure contacts the second terminal 3b of the template, but the arrangement of signal contacts with the ground terminal in a staggered pattern. 第一端子模板的导电端子3a的最远离焊接部32的为接地端子34,接下来才是信号端子,然后交替排列。 Farthest from the welding portion 3a of the first contacts 32 of the terminal board ground terminal 34, next is the signal terminal, and are alternately arranged. 而第二端子模组的导电端子3b的最远离焊接部32的为信号端子33,接下来才是接地端子34,然后交替排列。 3b and the second conductive terminal of the terminal module farthest from the welded portion of the signal terminal 33, the ground terminal 34 next is 32, then alternately arranged. 如此,在垂直于两端子模板的方向上,第一端子模板的信号端子恰好对齐第二端子模板的接地端子,第二端子模板的信号端子恰好对齐第一端子模板的接地端子,可达成在该方向上的屏蔽作用。 Thus, in a direction perpendicular to the two terminal modules, the first terminal of the template signal is properly aligned ground terminal of the second terminal of the template, the template signal terminal the second terminal of the first terminal is grounded properly aligned template, can be achieved in the shielding direction.

[0016] 屏蔽板13具有相对的第一壁面13a和第二壁面13b,其包括接触部131及连接部132,连接部呈平板状,其形状跟端子模板的所有导电端子3的连接部对应,但是没有断开, 接触部131自连接部的前端延伸出来且分别交替向两侧弯折,呈两排状,每排接触部131恰好位于每一端子模板的信号端子的差分信号对之间,图2所示。 [0016] The shield plate 13 having opposite first wall 13a and second wall 13b, which includes a contact portion 131 and the connection portion 132, connecting portion has a flat plate-shaped connecting portions of all contacts with the shape corresponding to the terminal board 3, but is not disconnected, the contact portion 131 distal from the connecting portion extending from and bent to both sides alternately, like in two rows, each row of the contact portion 131 is located just between the differential signal pair of signal terminals of each of the terminal modules, 2 shown in FIG. 屏蔽板设置于两端子模组之间,因其未设有焊接脚,还需要设置将屏蔽板与接地端子连接的结构,下面结合图5具体说明结构。 The shield plate is provided between the two terminal modules, because welding pin is not provided, but also need to set the configuration to the shield plate and the ground terminal is connected, the following detailed description in conjunction with the structure of FIG.

[0017] 结合图4、图5所示,屏蔽板13的第一壁面13a上利用金属的延展性分别向一侧冲压出凸肋134,而在相对的另一侧面则形成凹沟135,由于屏蔽板未设焊接脚,凸肋134抵接于接地端子34的连接部342上,以连接部342为中介,屏蔽板13可以间接地借用接地端子34的焊接脚340实现接地的功效(凸肋和接地端子之间为面接触,接地效果更好)。 [0017] in conjunction with FIG. 4, FIG. 5, the ductility of a metal on the first wall surface 13a of the shield plate 13 are punched out to the side of the rib 134, and on the other side is formed opposite the grooves 135, since shield does not have a welding pin, the rib 134 comes into contact with the ground connecting portion 342 terminal 34, the connecting portion 342 as an intermediary, the shield plate 13 may be indirectly borrow ground terminal welding pin 34 is 340 to achieve efficacy grounded (ribs and the surface contact between the ground terminal, the ground better). 因第一端子模板的导电端子3a跟第二端子模板的导电端子3b中的接地端子为上、下交错排列,故第一、第二壁面的冲压位置错开,第一、第二壁面13a、13b上的凸肋134a、134b彼此交错间隔排布,最终屏蔽板两壁面上的凸肋均能抵接到第一、第二端子模板中的接地端子上实现屏蔽接地。 3b by the conductive terminal contacts 3a of the first terminal with a second terminal of the template in the template is a ground terminal, the staggered, so that a first, a second wall offset from the punching position, the first and second walls 13a, 13b the ribs 134a, 134b are arranged staggered spaced from each other, the final wall surfaces of the shield plate ribs can contact the ground to achieve a ground terminal of the first shield, a second terminal of the template. 请注意,由于凸肋134与凹沟135是间隔排布的,而接地端子34与信号端子33也为间隔排布,这样当凸肋与接地端子抵接的时候,凹沟可对信号端子形成包围(凹沟使得信号端子在垂直于遮蔽板方向上的距离变宽,且凹沟的宽度设置的较信号端子宽), 这样屏蔽板13不仅可分隔两端子模板中的信号端子,对于同块端子模板中的信号端子同样被分隔开来,使得屏蔽效果更加出众,信号端子之间的串扰可被减小到最低。 Note that, since the rib 134 and grooves 135 are spaced arrangement, the ground terminals 34 and signal terminals 33 intervals arranged so that when the rib and the ground terminal comes into contact, grooves may be formed on the signal terminal enclosing (so that the signal terminal grooves widening in distance in the direction perpendicular to the shielding plate, and a width wider than the signal terminals provided grooved), so that the shield plate 13 may be separated not only signal terminals of the two terminal modules, for the same block signal terminals in terminal modules are spaced apart by the same, so that the shielding effect is more outstanding, crosstalk between the signal terminals can be reduced to a minimum. 本发明屏蔽板为贴合于两端子模板,减小了导电端子3a与导电端子3b之间的间距(同样减小了第一端子模板与第二端子模板之间的距离),这样可以制造出小体积的电连接器,符合目前电连接器小型化的发展趋势。 The present invention is a shielding plate attached to the two terminal modules, reducing the spacing between the conductive terminals and the conductive terminals 3a 3b (likewise reduces the distance between the first terminal and the second terminal template template), which can be manufactured small electrical connectors, electrical connectors in line with the current development trend of miniaturization.

[0018] 综上所述,本发明通过屏蔽板的凹沟135对信号端子33在其排布路径上进行包围,凸肋134则抵接于接地端子34在其排布路径上,这样设置可有效地对导电端子3实现接地的同时可分隔信号端子从而有效地降低信号端子之间的信号串扰。 [0018] In summary, the present invention is arranged to surround on its path through the grooves 135 pairs of signal terminals 33 of the shield plate, the rib 134 comes into contact with the ground terminal 34 are arranged in their path, can be arranged so while effectively grounding of the contacts 3 may be separated signal terminals thereby effectively reducing crosstalk between the signal terminals. 以上仅为本发明较佳的实施例,本发明并不以以上实施例为限制,但凡了解本案设计要点之人以此所作等效的变幻,均应涵盖本案权利要求内。 Above is merely a preferred embodiment of the present invention, the present invention is not restricted to the above embodiments is, whenever the person to understand this design point case equivalent changes made, should fall within the present disclosure claims.
