Description

具有屏蔽件的插式连接
技术领域
本发明涉及一种具有屏蔽件的插式连接，特别是由多点连接器插头和多点连接器插口构成的多排式多极插式连接，所述插式连接具有信号触点，所述信号触点按一定的接触图形布置成差动对，并与包围所述差动对的L型屏蔽元件一起构成触点组，其中，所述触点组成排成列布置，相邻列中的相邻触点组沿所述列的纵向彼此错开可规定的长度布置。
背景技术
同类型插式连接例如公开自DE 603 16 145 T2。在这种插式连接中，相邻列中的相邻触点组沿所述列的纵向错开可规定的长度布置。信号触点被L型屏蔽元件包围，但不是完全包围。出于这一原因，L型屏蔽元件逐列交替地旋转180°布置。此外，这种插式连接器的相邻列中的信号触点彼此错开一定长度布置，这个长度大体等于同一触点组中的信号触点之间的距离。这样的布置方式再加上L型屏蔽元件不完全遮蔽信号触点，以及屏蔽元件自身所采用的布置方式，使得该插式连接器无法在很高的频率范围内实现无干扰信号传输。
US 2001/0046810 A1以及US 6,328,602 B1所揭示的具有屏蔽件的插式连接器可以在减小信号触点间电磁耦合(串音)的同时提高密度和速度。
为此，US 20001/0046810 A1设置了一个电连接器，该连接器的具有屏蔽件的插接件设置在其中一个部分中并横向于第二部分中的屏蔽件定向。该连接器的一个部分由具有屏蔽件的晶片制成，这些屏蔽件定位在晶片之间。其中一个部分中的屏蔽件具有接触部，以便与另一部分中的屏蔽件建立电连接。通过这种方式而产生的连接器不但容易制造，屏蔽性能也得到了改善。
在US 6,328,602 B2所揭示的插式连接器中，相邻列中的信号触点和接地触点彼此错开布置，以便减少信号触点之间的串扰(串音)。屏蔽触点具有将信号接触元件部分包围的翼形突出部。这种结构很难实现信号接触元件和屏蔽接触元件的高密度分布。而且，这样一种连接器的信号特性也达不到最佳程度。
EP 1 470 618 B1也揭示过包括屏蔽件和信号触点的插式连接，信号触点按一定的接触图形布置成差动对，并与包围所述差动对的L型屏蔽元件一起构成触点组，其中，所述触点组成排成列布置。
电气工业领域经常用直角插式连接器在两个印制电路板(例如背板和固定在该背板上的印制电路板)或印制电路板与连接线之间建立电连接。为此需要将多点连接器插头布置在第一印制电路板上，在另一个印制电路板上布置与该多点连接器插头相匹配的多点连接器插口。随后再借助插式连接器的多点连接器插口将这个印制电路板固定到第一印制电路板上，并使两个印制电路板发生电接触。
这种连接器能达到很高的电信号传输频率。不仅需要对多点连接器插口和多点连接器插头内部的各种触点进行阻抗调整，以便抑制信号延迟和信号反射，还需为差动触点采用屏蔽措施。这种屏蔽效果通过EP 1 470 618 B1所提出的L型屏蔽件而实现。
为了达到最佳数据传输率，EP 1 470 618 B1提出一种设有信号触点的插接板，这些信号触点按一定的接触图形布置成成排成列定向的差动对，其中，每个差动对均包括两个彼此间隔第一距离的信号触点；每个差动对均与一个接地屏蔽件连接，其中，每个接地屏蔽件均包括一个刀片部，该刀片部沿两个信号触点的一侧在这两个信号触点所构成的差动对中延伸，每个接地屏蔽件均包括一个侧边部，该侧边部沿相应差动对的末端延伸，相邻差动对彼此间隔第二距离，该第二距离大于第一距离。每个接地屏蔽件的刀片部的顶端均突出在相应差动对的每个信号触点的外侧末端之外。
通过这样一种插式连接就能达到较高的数据传输率。但是由于触点组沿直线成排成列布置，不容易实现进一步的小型化。尤其是很难提高数据传输率。这种连接器的另一缺点是结构精细易损，很多情况下稳定性不足以支持多点连接器插头和多点连接器插口这两个插式连接元件的反复插拔操作。
发明内容
有鉴于此，本发明的目的是对同类型的具有屏蔽件的插式连接进行改进，在进一步提高数据传输率的同时改善该插式连接的耐用性，从而也能实现反复插拔操作。
就前述类型的具有屏蔽件的插式连接而言，本发明用以达成这个目的的解决方案为：相邻列中的相邻触点组彼此错开可规定的长度布置，其中，所述长度约为同一列中两个相邻触点组之间的距离的一半。通过这种方式不仅可以在同一列触点组之间以及相邻列触点组之间形成最大距离，从而实现信号触点的进一步小型化，还能通过增大相邻列信号触点之间的距离来进一步将数据传输率提高至25Gbit/sec.或以上。另一重要优点是，相邻列中的相邻触点组错开布置后，触点组之间会形成间隙，这些间隙一方面可以用来安置连接器壳体上的稳定元件，另一方面还可以起到改善相邻触点列之间的屏蔽效果的作用，下文还将对此进行详细说明。
本发明其他有利特征、设计方案及实施方式请参阅从属权利要求。根据一种特别有利的实施方式，所述可规定的长度约为同一列中两个相邻触点组之间的距离的一半。通过这种方式可以在同一列触点组之间以及相邻列触点组之间形成最大距离。
所述多点连接器插口的位于同一列中的触点组优选布置在同一个晶片中。这样能大幅简化连接器的制造，因为将这样的晶片叠层布置就可以形成该连接器。为了获得最佳屏蔽效果，本发明提出在相邻晶片之间各设置一个屏蔽片。由于相邻触点列中的触点组错开布置，这样就可以使这些屏蔽片的接触元件错开布置，从而与相邻触点组的屏蔽元件实现接触。为此，所述屏蔽片在其靠近插孔一侧优选具有多个弯曲并一端逐渐变细的接触弹簧，这些接触弹簧嵌在相邻晶片上与这些接触弹簧相匹配的槽口中。这种设计方案只有在相邻列触点组错开布置的情况下才能实现。只有这样才能确保，即使在结构进一步小型化的情况下，差动触点对也不会与屏蔽片的接触弹簧发生接触。因为，错开排布的布置方式使得差动触点对与屏蔽片的接触弹簧之间也形成了最大距离。为此，所述屏蔽片在所述弯曲并一端逐渐变细的接触弹簧区域内优选实施地相对较细。这样既能改善弹性效果，又能将有限的结构空间考虑在内。
所述多点连接器插头和所述多点连接器插口均是在电路板侧通过焊接或压接技术固定在电路板上并与电路板接触，为了能够在遵守连接器侧的规定网格尺寸的同时在电路板侧实现相对较小的网格尺寸，本发明提出的有利设计方案是：所述多点连接器插头的接触元件一端逐渐变细，从而使得相邻接触元件之间在电路板侧的距离略小于这些接触元件在连接器侧的距离。
优选通过在电路板侧对上述接触元件进行压印处理来实现这种一端逐渐变细的结构。这种结构也能批量制造。
根据一种特别有利的设计方案，多点连接器插头壳体上的加固筋布置在所述错开布置的触点组的形成间隙的区域内。如此一来，触点组列的两侧都将存在这样的加固筋，这些加固筋以间隔一个列宽的距离分布在触点组列左右两侧。这部分加固筋能显著提高极易受到影响的刀片壳体的稳定性。

具体实施方式
下文将借助附图所示的实施例对本发明的其他优点和特征进行说明。其中所述及的各项特征既可单独实现，也可相互结合。
图1右部所示是例如通过焊接或压接技术固定在电路板50上并与该电路板接触的多点连接器插口100。这个多点连接器插口的正面设有多个平行分布的触点组列120。每个触点组列120均具有多个堆叠布置且分别被一个L型屏蔽片103包围的差动触点对101、102。两个差动触点101、102和与之对应的屏蔽片103共同构成一个触点组。亦即，该连接器由多个触点组列和多个触点组排构成，其中，触点组排的特征在于，相邻触点组列中的相邻触点组错开可规定的长度布置，下文还将联系图2对此进行详细说明。
多点连接器插头200也具有触点组列220，其中，每两个触点组列200之间各设有一个其他触点组列221，这个其他触点组列的特征在于，触点组相对于相邻触点组列220的触点组错开相同的长度布置。
图2分别对触点组列120、220以及121、221进行了图示。为了简便起见，接触弹簧101、102或接触刀片201、202等接触元件以及相应的孔口103和L型屏蔽片203等屏蔽元件从上到下用连续的字母a)、b)、c)、d)至l)表示。如图2所示，差动接触元件101、102或201、202之间的距离为l1。由差动触点对101、102或201、202和屏蔽元件103或203构成的相邻触点组之间的距离为l2。其中，触点组彼此错开布置，使得触点组列120、220中的每个触点组与相邻列121、221中的相邻触点组之间的距离均为l3。这个距离l3优选为同一列120、220或121、221中的相邻触点组之间的距离的一半，即l3＝l2/2。借此在差动触点对之间形成最大距离。这种排布方式与下文所述的重要优点紧密相关。
图3a、图3b以及图4所示涉及的是多点连接器插口的结构。据此，单个的触点列是单个晶片180的一部分。如图3a或图3b所示，晶片180叠层并排布置，晶片之间设有屏蔽片300，下文还将对这些屏蔽片进行详细说明。整个结构固定在壳体元件181中，该壳体元件还对多点连接器插口起稳定作用。连接器侧设有护罩182，该护罩上设有与插接面相对应的开口。图4为单个晶片180的视图。布置在连接器侧的差动触点对101、102之间的距离例如为1.3mm。如图4所示，差动触点对101、102分别通过相应在晶片180中成角度分布的导线191、192与电路板侧的连接元件107、108连接。电路板侧连接元件107、108之间的距离略小于连接器侧连接触点之间的距离。电路板侧连接元件107、108之间的距离优选为1.2mm。电路板侧信号接触元件107、108之间设有屏蔽触点109。
图5所示就是所谓的“插接面”，该图示出的是正面护罩182的正视图。由信号元件101、102构成的触点组被L型屏蔽元件103包围，相邻列中的触点组与这些触点组错开布置。采用这种错开布置方式后，每两个相邻列之间都会形成一个间隙130，设置在多点连接器插头200上的加固筋230嵌在这些间隙内。这样能大幅提高这种插式连接的稳定性，从而可以反复实施插接操作。
如图6和图7所示，采用金属导电设计的屏蔽片300在其靠近连接器侧的一侧具有屏蔽接触弹簧310，这些屏蔽接触弹簧各具有一个用于增强弹性效果的缝隙312。这些屏蔽接触弹簧元件的前部区域弯曲并逐渐变细。这种“逐渐变细”结构，即顶端333区域内相对较细的结构，可以通过压印工艺形成。弯曲顶端333嵌在多点连接器插口晶片180上与这些顶端相匹配的槽口182中。槽口182所采用的设计(图6和图7)使得弯曲顶端333分别与信号接触口101、102错开布置，并且在多点连接器插口和多点连接器插头插接起来后与相应的L型屏蔽片203发生电接触。在触点组错开布置的情况下，通过这种方式可以在屏蔽元件与差动触点对之间实现最大距离，只有这样才能达到25Gbit/sec.或以上的数据传输率。
下面参照图8对多点连接器插头的结构进行简短说明。差动触点对201、202以及将这些差动触点对包围的L型屏蔽元件203布置在多点连接器插头的壳体210中。其中，差动接触元件的连接器侧间距(例如1.3mm)大于电路板侧间距(例如1.2mm)。具体实现方法是在接触元件201、202上设置压印结构232、233(图9)。借此可以加大电路板上的接触元件密度。
图10为多点连接器插头的俯视图。壳体210中设有被L型屏蔽片203包围的差动触点对201、202。为了简便起见，图10中也是连续用a)、b)...k)、l)表示差动接触元件，其中，相邻差动接触元件201、202之间的距离为l1，同一列220或221中的相邻触点组之间的距离为l2。相邻列中的相邻触点组之间的距离，即列220中每个触点组与列221中的相邻触点组之间的距离为l3，其中，l3大体等于l2/2。即l3＝l2/2。这种错开排布的布置方式有助于进一步小型化，因而能改善数据传输质量，此外通过在多点连接器插头上的错开列221、220区域内设置加固筋230，还能提高稳定性。如上所述，这些加固筋嵌在多点连接器插口上因采用错开布置方式而形成的间隙130内。
图11为差动触点对201、202和屏蔽接触元件203a在多点连接器插头上的排布或布局。从这个图中也能看出，相邻触点组之间的距离为l1，在图11中用序号1至14表示的相邻列彼此间错开距离l3，其中，l3＝l2/2。距离l2是同一列中相邻触点组之间的距离。从图11中可以非常清楚地看到差动触点对201、202和屏蔽(接地)接触元件203a(另见图8)在排布上的对称性，本申请人所做的大量实验结果表明，只有这样才能达到较高的信号传输率，尤其是能达到较高的信号传输频率。
