高速系统架构使用PCB作为信号传输的媒介。随着信号传输速率的提高以及信号传输带宽的增加，信号传输的插入损耗也随之增加。为了降低插入损耗，在一些相关技术中，使用线缆代替PCB作为信号传输的媒介。
一方面，相比于PCB，线缆单位长度插入损耗更低；另一方面，由于使用PCB作为信号传输的媒介，信号传输需要依托于PCB走线，相比于使用压接传输信号的PCB走线，线缆具有更大的灵活性。
使用线缆有效减少了信号传输过程中的插入损耗。但在实际的高速系统架构中，尤其是正交高速系统架构中，由于公差以及结构变形(如单板变形)的累积，造成单板之间的连接的器件(如连接器)无法在完全配合状态，即非完全配合状态(de-mate)下工作，使用线缆代替PCB作为信号传输的媒介却无法解决。
而连接器在非完全配合状态(de-mate)下工作，相比其在完全配合状 态(full-mate)工作，阻抗特性和插入损耗都会发生明显的劣化。尤其当信号传输带宽到达一定阈值，连接器插入损耗(及插入损耗波动)会发生尤为明显的劣化。而业务期望的高速串行单通道信号的速率(SerDes速率)为112Gbps甚至更高。此时，连接器的工作频点在28GHz(在0～42GHz范围内波动)，达到了连接器性能发生明显劣化的阈值。因此，连接器在非完全配合状态下工作带来的性能劣化对信号传输的影响是不可忽略的。
连接器在非完全配合状态下工作，不仅会造成连接器性能的下降，而且为了保证连接器在非完全配合状态下工作时的机械接触，连接器的端子需要设计更长的摩擦距离。而为了保证在较长摩擦距离情况下连接器的性能和鲁棒性，连接器的设计复杂度和设计成本都又进一步大大增加。
在一些相关技术中，使用设计复杂度更高的连接器升级来保证连接器在非完全配合状态下工作也有较好的性能，但设计复杂度更高的连接器迭代周期长，尤其是使其与现有产品兼容的挑战巨大。
在另一些相关技术中，通过对高速系统架构中单板变形以及公差等进行限制来保证连接器尽量在完全配合状态下工作以保证连接器的性能。但即使当前结构设计已经采取先进的面板扳手及螺钉锁定设计，尽可能使得公差累积集中在单板而不是单板连接(如连接器)处，但仍由于机框和单板的尺寸较大、结构变形等因素造成连接器还是会在非完全配合的状态下工作，即会存在一定的de-mate距离。而即使是1.0mm的de-mate距离，连接器的性能也会发生明显的劣化。
第一方面，参照图1至图8，本公开实施例提供一种线缆连接结构，其包括：
承载件101，该承载件上设有至少一个线缆连接器104，每个线缆连接器104具有与线缆12连接的第一端口，以及与第一端口电连接的第二端口；以及
与承载件101连接的滑动结构102，该承载件101被构造成通过滑动结构102与单板11连接，承载件101能使与其连接的单板11在第一方向 上滑动，第一方向为接近或远离承载件101上的线缆连接器104的第二端口的方向。
本公开实施例的线缆连接结构具体包括承载件101、至少一个在承载件101上固定设置的线缆连接器104以及与承载件101连接的滑动结构102。
其中，线缆连接器104固定于承载件101。例如，线缆连接器104可通过压接的方式固定于承载件101(当然该压接管脚不具有信号传输功能，仅仅是起到固定作用)。当然，线缆连接器104也可通过其他方式固定于承载件101(例如焊接、粘结、卡接等)。
线缆连接器104具有第一端口和第二端口，第一端口被构造成与线缆12连接，第二端口在与第一端口电连接的同时也可与其他端口连接。即信号可以通过线缆12传输至与线缆12连接的第一端口，再传输至与第一端口连接的第二端口连接的其他端口。
与承载件101连接的滑动结构102具体可以是滑轨，承载件101通过滑动结构102可以与单板11连接，与承载件101连接的单板11可以通过滑动结构102在第一方向上滑动，该方向为接近或远离线缆连接器104的第二端口的方向。滑动是相对的。若与滑动结构102连接的单板11固定不能滑动，则承载件101可以相对于单板11沿着第一方向滑动。
本公开实施例的线缆连接结构，通过将线缆连接器104固定于与单板11可相对滑动的承载件101上，使得线缆连接器104相对于单板11在一定方向上位置可以发生变化。当单板11变形或公差，无法满足线缆连接器104在要求的位置上时，即无法满足线缆连接器104在完全配合的状态下工作时，通过滑动结构102，使线缆连接器104与单板11的相对位置发生变化，使线缆连接器104依然处于可以在完全配合的状态下的位置，以保证线缆连接器104依然可以在完全配合的状态下工作。这种方式避免了当单板11变形或公差累积在连接器，使得连接器在非完全配合状态下工作，而造成连接器性能的下降，影响信号的传输。
在一些实施例中，参照图1至图8，承载件101为板状，其上设有多个线缆连接器104，多个线缆连接器104沿垂直于第一方向的方向依次设置。
本公开实施例的线缆连接结构的承载件101具体可以为板状。具体地说，该承载件可以是单板11，尺寸可小于一般的单板11。在承载件101上固定有多个线缆连接器104，多个线缆连接器104沿垂直与第一方向的方向设置，即线缆连接器104的设置方向为垂直与单板11的滑动方向。
由于承载件101与单板11通过滑动结构102连接，因此，承载件101在垂直于第一方向上的长度是固定的，将线缆连接器104沿垂直与第一方向的方向设置可以保证承载件101垂直于第一方向上的长度被充分利用(若将线缆连接器104沿平行与第一方向的方向设置，则承载件101垂直于第一方向上的长度只有一个线缆连接器104的长度被利用)，减少承载件101的大小。
在一些实施例中，线缆连接结构还包括滑动锁定装置103，该滑动锁定装置被构造成将滑动结构102相对承载件101固定。
本公开实施例的线缆连接结构还包括滑动锁定装置103，通过滑动锁定装置103可以将滑动结构102相对于承载件101固定。本质上，滑动锁定装置允许与滑动结构102连接的单板11与承载件101实现发刚性结构关系，相对位置固定。也就是说，当滑动锁定装置103锁定时，与滑动结构102连接的单板11固定不能滑动，承载件101也固定不能滑动；当滑动锁定装置103解锁时，与滑动结构102连接的单板11可以相对于承载件101滑动(与滑动结构102连接的单板11沿滑动结构102滑动或者承载件101沿滑动结构102滑动或者两者都可以沿滑动结构102滑动)。
通过滑动锁定装置103，在与滑动结构102连接的单板11与承载件101之间的连接已经设定好，不希望发生相对位置发生变化时，可以将与滑动结构102连接的单板11与承载件101的相对位置固定，方便其作为一个整体安装或移动。
第二方面，参照图2，本公开实施例提供一种单板组件1，该单板组件包括：单板11以及上述任意一种线缆连接结构，其中，单板11通过滑动结构102与承载件101滑动连接；
单板11包括至少一个线缆接口111；
单板组件1还包括连接在线缆接口111与线缆连接器104的第一端口之间的线缆12。
本公开实施例的单板组件1具体包括上述任意一种线缆连接结构、以及通过线缆连接结构的滑动结构102与线缆连接结构的承载件101滑动连接的单板11。单板11上设有至少一个线缆接口111(其具体也可以是线缆连接器)，线缆接口111可以设于单板11的任何位置(如板上、板边等)。单板11上的线缆接口111通过线缆12与线缆连接结构的线缆连接器104的第一端口连接。
其中，单板11具体可以是业务单板、交换网板等。单板11上的线缆接口111与线缆连接结构的线缆连接器104可以是一对一的关系，即单板11上每一个线缆接口111连接线缆连接结构的不同的线缆连接器104的第一端口；单板11上的线缆接口111与线缆连接结构的线缆连接器104可以是一对多的关系，即单板11上每一个线缆接口111连接线缆连接结构的多个不同的线缆连接器104的第一端口；单板11上的线缆接口111与线缆连接结构的线缆连接器104可以是多对一的关系，即线缆连接结构的每个线缆连接器104的第一端口连接多个不同的单板11上的线缆接口111。
线缆12相比较于PCB具有灵活性，线缆连接器104与单板11通过线缆12连接，线缆连接器104与单板11的相对位置即使发生变化，通过线缆12连接，也不会影响信号的传输。
本公开实施例的单板组件1，利用线缆12的灵活性，通过将线缆连接器104固定于与单板11可相对滑动的承载件101上，使得线缆连接器104相对于单板11在一定方向上位置可以发生变化。当单板11变形或公差，无法满足线缆连接器104在要求的位置上时，即无法满足线缆连接器104 在完全配合的状态下工作时，通过滑动结构102，使线缆连接器104与单板11的相对位置发生变化，使线缆连接器104依然处于可以在完全配合的状态下的位置，以保证线缆连接器104依然可以在完全配合的状态下工作。这种方式避免了当单板11变形或公差累积在连接器，使得连接器在非完全配合状态下工作，而造成连接器性能的下降，影响信号的传输。
第三方面，参照图1至图8，本公开实施例提供一种单板组件连接结构，该单板组件连接结构包括：
第一单板组件组，其包括至少一个上述任意一种单板组件1；
第二单板组件组，其包括至少一个上述任意一种单板组件2；
第一单板组件组中的每个单板组件1中至少有一个线缆连接器104的第二端口与第二单板组件组中的一个单板组件2的线缆连接器204的第二端口电连接。
为了区分第一单板组件组和第二单板组件组，在图1至图8中将第二单板组件组的单板组件标为2，每一个单板组件2包括承载件201、滑动结构202、位于承载件201上的线缆连接器204；在一些实施例中，单板组件2还包括滑动锁定结构203。但单板组件2和单板组件1具有本质上一样的结构，都是本公开实施例的单板组件。
本公开实施例的单板组件连接结构具体包括第一单板组件组和第二单板组件组，每一组单板组件都包括至少一个上述的单板组件1或2。第一单板组件组的每个单板组件1都至少有一个线缆连接器104的第二端口与第二单板组件组其中一个单板组件2的线缆连接器204的第二端口电连接。
本公开实施例的单板组件连接结构，通过将线缆连接器104固定于与单板11可相对滑动的承载件101上，使得线缆连接器104相对于单板11在一定方向上位置可以发生变化。当单板11变形或公差，无法满足线缆连接器104在要求的位置上时，即无法满足线缆连接器104在完全配合的状态下工作时，通过滑动结构102，使线缆连接器104与单板11的相对位 置发生变化，使线缆连接器104依然处于可以在完全配合的状态下的位置，以保证线缆连接器104依然可以在完全配合的状态下工作，这种方式避免了当单板11变形或公差累积在连接器，使得连接器在非完全配合状态下工作，而造成连接器性能的下降，影响信号的传输。
在一些实施例中，参照图1至图4，第一单板组件组中每个单板组件1中至少有一个线缆连接器104的第二端口与第二单板组件组中的一个单板组件2的线缆连接器204的第二端口连接。
本公开实施例的单板组件连接结构中，第一单板组件组的每个单板组件1都至少有一个线缆连接器104的第二端口与第二单板组件组其中一个单板组件2的线缆连接器204的第二端口连接，这里的连接是指连接的不同组的线缆连接器104或204在完全配合状态下的连接。
也就是说，第一单板组件组中每个单板组件1中至少有一个线缆连接器104的第二端口与第二单板组件组中的一个单板组件2的线缆连接器204的第二端口直接连接，而不是通过其他端口或者线缆12等电连接。
在一些实施例中，参照图2和图3，第一单板组件组包括多个上述的任意一种单板组件1，其中各单板组件1的单板11相互平行；第二单板组件组包括多个上述的任意一种单板组件2，其中各单板组件2的单板21相互平行，并且与第一单板组件组中的单板11间的夹角大于0度且小于等于90度。
本公开实施例的单板组件连接结构中，第一单板组件组包括多个单板组件1，第二单板组件组包括多个单板组件2。
具体的，第一单板组件组和第二单板组件组中的单板11或21可以为业务单板或者交换网板等，其通常为板状。第一单板组件组各单板组件1的单板11相互平行，第二单板组件组各单板组件2的单板21相互平行。不同组的单板组件的单板(即单板11与单板21)之间为特定夹角(即相对倾斜)。
不同组的单板组件的单板相对倾斜，每个单板组件的单板可以与另一单板组件组中多个单板组件的单板相交，实现更多的连接。进一步的，单板11与单板21之间的夹角大于60度且小于等于90度，更进一步的，如图2所示，单板21与单板11间的夹角为等于90度，第一单板组件组和第二单板组件组组成正交高速系统架构。
通过本公开实施例的第一单板组件组和第二单板组件组，可以实现第一单板组件组的单板11上的线缆接口111经线缆12与第一单板组件组的单板组件1中线缆连接结构的线缆连接器104的第一端口的连接，第一单板组件组中的线缆连接器104的第二端口与第二单板组件组中的线缆连接器204的第二端口的连接，以及第二单板组件组中的线缆连接器204的第一端口经线缆22与第二单板组件组的单板21上的线缆接口211的连接。通过这种方式，可以实现信号从第一单板组件组的单板11到第二单板组件组的单板21的传输。当然，信号也可以反向传输，即从第二单板组件组的单板21传输至第一单板组件组的单板11。
在一些实施例中，单板组件连接结构还包括被构造成将第一单板组件组的线缆连接器104和与其电连接的第二单板组件2的线缆连接器204锁定的连接锁定装置3。
本公开实施例的单板组件连接结构还包括被构造成锁定第一单板组件组的线缆连接器104和第二单板组件组的线缆连接器204的连接锁定装置3。
当第一单板组件组的线缆连接器104的第二端口与第二单板组件组的线缆连接器204的第二端口连接，即第一单板组件组的线缆连接器104与第二单板组件组的线缆连接器204完全配合时，连接锁定装置3锁定，以固定第一单板组件组的线缆连接器104与第二单板组件组的线缆连接器204的连接状态。这样，第一单板组件组的线缆连接器104与第二单板组件组的线缆连接器204始终完全配合，保证第一单板组件组的线缆连接器104与第二单板组件组的线缆连接器204在完全配合的状态下工作。
在一些实施例中，参照图4，单板组件连接结构还包括固定框5，第一单板组件组和第二单板组件组位于固定框5的相对侧。
本公开实施例的单板组件连接结构还包括固定框5，该固定框具体可以是系统机框，第一单板组件组和第二单板组件组分别位于固定框两侧。固定框5上具有供单板11或单板21插入的卡槽。当单板11或单板21完全插入卡槽时，则可以认为单板11或单板21对应的线缆连接器104或线缆连接器204也在正确的位置。当与该线缆连接器104或204连接的线缆连接器204或104对应的单板21或单板11也完全插入固定框5时，则说明两个线缆连接器104和204已正确连接，处于完全配合的状态。
在一些实施例中，本公开实施例的单板组件连接结构的单板组件1或2都包括滑动锁定装置，则其组装过程具体可以是：
滑动锁定装置103或203锁定，线缆连接结构的承载件101或201与单板组件1或2的单板11或21变为刚性结构关系，并且相对位置固定。将单板11或21与承载件101或102相对位置固定的单板组件1或2的单板11或21插入固定框5，以方便其上线缆连接器104或204的第二端口可以与对应组的单板组件2或1的线缆连接器204或104的第二端口连接。
当第一单板组件组和第二单板组件组的单板组件1和2都完全插入固定框5，即第一单板组件组的线缆连接器104与第二单板组件组的线缆连接器204完全配合时，将连接锁定装置3锁定，以固定第一单板组件组的线缆连接器104与第二单板组件组的线缆连接器204的连接状态。同时对滑动锁定装置103和203进行解锁，使得单板11和12可以沿滑动结构102和202滑动。
当存在单板11或21变形或公差，使得在第一单板组件组的线缆连接器104与第二单板组件组的线缆连接器204在完全配合的状态下工作时，单板11或21未达到其预定位置(如单板11或21的另一侧无法完全与系统的其他部件连接)，使得单板组件连接结构所在的系统无法正常工作，则通过单板11或21滑动，使单板11或21到达其预定的位置(即线缆连 接器104或204位置不动，单板11或21可以滑动，不完全插入固定框5)，以保证单板组件连接结构所在的系统可以正常工作。同时，第一单板组件组的线缆连接器104与第二单板组件组的线缆连接器204也在完全配合的状态下工作。
在一些实施例中，单板组件连接结构的线缆连接结构还包括滑动锁定装置103或203。
参照图6，单板组件连接结构还包括联动结构4，该联动结构被构造成将连接锁定装置3置于锁定状态，并将滑动锁定装置置于解锁状态；或将连接锁定装置3置于解锁状态，并将滑动锁定装置置于锁定状态。
本公开实施例的单板组件连接结构还包括滑动锁定装置103或203、连接锁定装置3以及联动结构4。
当单板组件1或2的滑动锁定装置103或203在锁定状态时，单板组件1或2的单板11或21与承载件101或201实现刚性结构关系，并且相对位置固定。当单板组件1或2的滑动锁定装置103或203在解锁状态时，单板组件1或2的单板11或12可相对承载件101或201在第一方向滑动。
当连接锁定装置3在锁定状态时，第一单板组件组的线缆连接器104的第二端口与第二单板组件组的线缆连接器204的第二端口连接，即第一单板组件组的线缆连接器104与第二单板组件组的线缆连接器204完全配合。当连接锁定装置3在解锁状态时，第一单板组件组的线缆连接器104的第二端口与第二单板组件组的线缆连接器204的第二端口的位置可以相对发生变化。
联动结构4则是将滑动锁定装置103或203和连接锁定装置3联动，以保证当连接锁定装置3在锁定状态，滑动锁定装置在解锁状态；或当连接锁定装置3在解锁状态，滑动锁定装置在锁定状态。
通过联动结构4，可以实现连接锁定装置3和滑动锁定装置103或203的联动，避免连接锁定装置3和滑动锁定装置103或203处于同样的状态，导致本公开实施例的单板组件连接结构无法正常工作。如连接锁定装置3 和滑动锁定装置103或203都处于解锁状态，则在单板11或21滑动的同时，承载件101或201也可能会滑动，导致第一单板组件组的线缆连接器104与第二单板组件组的线缆连接器204不能完全配合。
当然，也可以参照图5，单板组件连接结构不包括联动结构4，则可通过人工控制来将连接锁定装置3置于锁定状态，并将滑动锁定装置置于解锁状态；或将连接锁定装置3置于解锁状态，并将滑动锁定装置置于锁定状态。
在一些实施例中，参照图7和图8，板组件连接结构还包括背板6；
承载件101或201连接背板6；
背板6具有第三端口，第三端口与第二端口连接，且第一单板组件组中的单板组件1的第二端口连接的第三端口通过连接电路连接另一个第三端口，该另一个第三端口与第二单板组件组中的单板组件2的第二端口连接。
参照图7，承载件101或201连接背板6，第一单板组件组中每个单板组件1的线缆连接器104的第二端口，也可连接背板6上的背板连接器，即线缆连接器104的第二端口与背板连接器在完全配合状态下。第二单板组件组中每个单板组件2的线缆连接器204的第二端口也连接背板连接器的另一个端口，同样也在完全配合状态下。
背板6上具有多个背板连接器。连接同一个背板连接器的不同端口的第一单板组件组中的线缆连接器104与第二单板组件组中的线缆连接器204通过背板连接器电连接。由于每一个单板组件1或2的线缆连接器104或204都和背板连接器在完全配合状态下，第一单板组件组中的线缆连接器104与第二单板组件组中的线缆连接器204自然在完全配合状态下。
当然，参照图8，第一单板组件组和第二单板组件组可以位于背板6的同一侧。此时，背板6上不同的背板连接器电连接。连接电连接的两个背板连接器的第一单板组件组中的线缆连接器104与第二单板组件组中的线缆连接器204也通过这两个背板连接器实现连接。
在实际结构中，第二单板组件组也可以替换为传统的PCB压接连接器，也就是说，第一单板组件组中单板组件1的线缆连接器104的第二端口通过背板连接器与PCB压接连接器连接，实现信号的传输。
