具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开实施例的一些方面相一致的装置和方法的例子。
另外，本说明书中的表示方向、方位的术语，例如“上”“下”“长”“宽”“高”等，其目的在于说明各构成要素的相对位置关系，并非旨在对各构成要素的朝向、设置位置进行限定。
图1及图2示意性地示出了一实施例的电源分配单元的内部结构及外部结构。
电源分配单元可以应用于机柜、大功率服务器以及数据中心等设备中。如图1和图2所示，电源分配单元整体细长，本说明书中，将电源分配单元的长度方向称为第一方向，将厚度方向(高度方向)称为第二方向，将宽度方向称为第三方向。如图1所示，该电源分配单元包括：接线端子1、至少一个接线盘2、多个电力输出端子组3和多个开关机构4。这些构成要素收纳于壳体5中。
在一个实施例中，如图1和图5所示，在电源分配单元的壳体5的内部，在靠近第一方向的一端部的位置设有接线端子1。接线端子1包括电源电力的输入端11和电源电力的引出端12，输入端11与外部的供电线连接，引出端12与每个接线盘2连接，在包括多根供电线或多个接线盘2的情况下，各供电线可以分别连接于输入端11的各个进线端子，各接线盘2可以分别连接于引出端12的各个出线端子。
如图1所示，多个接线盘2例如沿第一方向延伸且彼此并列地固定在壳体5的内部。各接线盘2彼此独立地设置。各接线盘2的形状、延伸长度等可以相同，也可以不同；各接线盘2的功率可以相同，也可以不同。在本实施例中，接线盘2为接线铜盘，但是，只要能够实现从接线端子1引出电力，对接线盘的结构、材质没有特别限定。另外，在图1所示的实施例中，多个接线盘2在壳体5中配置于壳体5的宽度方向上的一侧，但是接线盘在壳体中的配置位置并不限定于此。
下面，对电力输出端子及电力输出端子组进线说明。
如图1和图2所示，在壳体5的与接线盘所在侧相对的一侧，电力输出端子31以部分露出于壳体外部的方式设有多个。各电力输出端子31分别与接线盘2电连接。电力输出端子31例如包括与接线盘2电连接而接受电力供给的线缆和连接于线缆的端部供插头连接的插座。关于线缆的长度，本实施例不进行具体限定，每个电力输出端子31的线缆的长度可以相同，也可以不同。
如图1、图2所示，设于壳体5的电力输出端子31可以是部分线缆以及插座露出于壳体外部。通过这样将电力输出端子31设置成部分线缆以及插座露出于壳体外部，能够大幅降低壳体5的尺寸，或是可以在壳体尺寸相对固定的情况下，增加电力输出端子31的数量，满足更多电子设备的用电需求。但是，关于电力输出端子31的露出部分并不限于上述的方式，也可以如图8所示那样仅插座(例如仅插座的设有插孔的表面)露出于壳体外部。
这些电力输出端子31可以分为多个电力输出端子组3。各电力输出端子组3可以由至少一个电力输出端子31构成，应理解，本实施例对每个电力输出端子组3包括的电力输出端子31的数量不进行限定，可以是2个，也可以是3个、4个或者更多个，本领域技术人员可以根据应用场景具体地设定。另外，各电力输出端子组3未必全部由相同数量的电力输出端子31构成，也可以使一部分电力输出端子组3中的电力输出端子31的数量有变化。
如图1、图2、图8所示，多个电力输出端子组3沿电源分配单元的长度方向(第一方向)排列，并贯穿壳体5的沿第一方向延伸的一个侧壁(第一侧壁51)而部分地露出于壳体外部。
对应着各个电力输出端子组3，设置有多个开关机构4。开关机构4控制所对应的电力输出端子组3与接线盘2的电连接或电关断，实现了对各电力输出端子组3的独立控制以及独立保护。在本实施例中，针对一个电力输出端子组3，对应地设置一个开关机构4。
通过上述这样的、开关机构4与由多个(例如2个)电力输出端子31构成的电力输出端子组对应地设置且各开关机构4控制其各自对应的电力输出端子组3这样的结构，能够实现电源分配单元中多插座的分组控制，能够满足多种使用需求，提高了使用灵活性。
如图1、图2和图4所示，各开关机构4以至少开关机构4的开关杆43(在后说明)露出于壳体5的外部的方式凸设于壳体5的设有电力输出端子31的侧壁(例如第一侧壁51)。在一个实施例中，各 开关机构4配置在与所对应的电力输出端子组3邻近的位置，且沿第一方向排列。各开关机构4还可以在电源分配单元的厚度方向(第二方向)上重叠地配置，例如每两个开关机构4在第二方向上重叠配置而形成开关机构的重叠体，该重叠体沿着第一方向排列地设于所对应的电力输出端子组3的附近。关于在第二方向上重叠设置的开关机构4的数量，本实施例不进行具体限定，可以是2个，也可以是3个，或者是多个，具体可以根据用户需求、电源分配单元的安装空间等进行设置。
在本发明一些实施例中，可以由多个电力输出端子组组成至少2个电力输出单元，例如当电力输出端子组由2个电力输出端子31组成时，可以是每2个电力输出组组成1个电力输出单元。多个电力输出单元沿着第一方向排列地设置于壳体的第一侧壁51，且各电力输出单元彼此间隔设置。作为一例，各电力输出单元与开关机构4或是开关机构的重叠体沿第一方向交替地设置。
通过如上所述那样布置开关机构4与电力输出端子组3，能够充分利用电源分配单元的空间，在不增加电源分配单元的安装空间的情况下提高电源分配与控制的灵活度。而且，相比由一个总开关控制所有输出端子的传统的电源分配单元而言，本实施例的每一路电力输出端子31的输出功率可以更大，进而增加了电源分配单元整体的输出功率。另外，还可以增加电力输出端子31的数量，满足设备需求。
示例性的，当电源分配单元应用于矿机时，参见图1、图2、图8，电力输出端子组3可以包括4个电力输出端子31，4个电力输出端子31两两为一组，两个开关机构4在第二方向上重合设置；其中的一组电力输出端子31(即，一个电力输出端子组)可以由重叠的开关机构4中的一个控制，其中的另一组电力输出端子31(即，另一个电力输出端子组)可以由重叠的开关机构4中的另一个控制，即每个开关机构4控制2个电力输出端子31，在开关机构4控制所对应的电力输出端子31的线缆与接线盘2电连接时，2个线缆连接的矿机启动。
通过如上所述的设置既能保证开关机构4对外接用电设备的独立控制，也能减小开关机构4过多带来的操作复杂性。
下面，关于开关机构4的结构进行说明。
在一个实施例中，如图3和图4所示，开关机构4包括开关主体、设于开关主体的一端部的开关杆43。在开关主体设有供线缆通过的异形孔42，该异形孔42具有非圆形的内周面，因此能够在允许线缆通过的同时限制线缆的移动(例如转动、窜动)。通过异形孔42能够将线缆固定得更牢固，不易移动，防止因线缆的活动而造成的通电故障。开关杆43供用户进行断开或接通的操作，因此用户可以方便用户控制对应的电力输出端子31的电力输出，操作简单。
另外，如图3和图5所示，开关机构4还包括开关机构安装用固定槽41。固定槽41例如设置在开关主体上与开关杆43相对的位置。通过该固定槽41与在电源分配单元的壳体5设置的固定导轨55相配合(例如相卡合)，能够将开关机构4容易地固定于壳体5。作为一例，固定导轨55例如安装于壳体5的底壁，固定导轨55包括安装状态下相对于底壁呈竖立状态(沿第二方向延伸的状态)的竖立壁，该竖立壁(例如该竖立壁的两端部)能够与开关机构4的固定槽41相卡合。
当开关机构4在第二方向上与另一个开关机构4重叠地设置时，重叠状态的两个开关机构4均与固定导轨55相配合。这样，能够以简单且节省安装空间的方式容易地安装各开关机构4，而且无需额外设置对重叠的开关机构4进行对位的结构或是工序。
另外，关于固定导轨55的高度(第二方向上的长度尺寸)，只要能够与重叠的各开关机构4相卡合即可，没有特别限制。但是从抑制电源分配单元的厚度角度来考虑，优选固定导轨55的高度不高于与其卡合的开关机构4的总高度。
作为示例，如图4所示，固定槽41可以为燕尾槽。通过燕尾槽与固定导轨55之间的相互配合，可以使得开关机构4与固定导轨55卡合得更稳定，更牢固，不易晃动。
如图2所示，壳体5具有沿第一方向延伸的第一侧壁51和第二侧壁52、连接于两侧壁51、52的第一方向上的两端部的第一端壁53和第二端壁54、以及沿着第二方向覆盖由第一侧壁51、第二侧壁52、第一端壁53和第二端壁54围成的空间的彼此相对的顶壁和底壁。
在一个实施例中，在壳体5的第一方向上的一端，例如第一端壁53设有输入进线机构6。
在一个实施例中，输入进线机构6与接线端子1的输入端11电连接，接线端子1的引出端12与每个接线盘2连接；且接线端子1位于壳体5内且靠近第一端壁53的位置，这样可以降低输电线的长度，合理利用壳体内部空间。
作为示例，参见图6，输入进线机构6包括：第一集线环61和第二集线环62。
在一个实施例中，第一集线环61设置于第一端壁53的壳体5外部侧；第二集线环62设置于第一端壁53的壳体5内部侧。其中，第一集线环61环绕设置安装槽，在壳体5的第一端壁53设有供线缆穿过的贯通孔，这样，通过安装槽与贯通孔的连通，第一集线环61与第二集线环62贯通相连。
输入进线机构6采用环形结构的设置，能够适应更大体积的进线，更能满足大功率服务器的需求。关于第一集线环61和第二集线环62的内径尺寸，本实施例不进行具体限定，可以根据当前用电设备的需求功率或者壳体尺寸来进行确定，以满足不同设备的需求。
作为示例，如图7所示，本实施例的输入进线机构6还可以包括锁紧机构63。该锁紧机构63被配置为将外部进线的线缆固定在壳体5内。作为一例，锁紧机构例如呈倒U字型，锁紧机构覆盖在外部进线的线缆上，倒U字型的开口两端的凸缘固定于壳体5的底壁，从而对外部进线的线缆进线固定。另外，还可以在该锁紧机构63的与线缆接触侧设置至少一个凸肋(未图示)，在安装状态下，凸肋抵接于线缆的外表面，起到夹紧线缆固定的作用。
上述输入进线机构6采用环形结构供线缆穿过，能够适应更大体积的进线，增加输入功率；在壳体内部设置锁紧机构对外部进线的线缆进行固定，即使是大体积的进线，也能够可靠地固定进线的线缆。
另外，作为一例，可以如图1、图2、图8所示那样在壳体5的远离输入进线机构6的一端，例如在第二端壁54上也设置插座，由此进一步增加了电力输出的数量，这样，在不占用电力输出端子组3的位置的情况下，进一步提高了电力分配单元的空间利用率。另外也可以使不同类型的受电设备设置在不同表面，方便管理，无需另外设置插座插排等。应理解，在第二端壁54设置的输出端子，不仅可以包括插座，也可以是包括线缆和插座。同样的，在第二端壁54设置的输出端子，可以受与之邻近的开关机构4的控制，也可以受电源分配单元的总开关的控制，当然也可以受其他开关机构的控制。
作为示例，电源分配单元还包括例如安装服务器的安装架等安装支架。作为一例，如图1、图2和图8所示，电源分配单元包括第一安装支架7和第二安装支架8。
作为一例，第一安装支架7设于壳体5的第一端壁53外侧且与壳体5的第一端壁53相连，第二 安装支架8设于壳体5的第二端壁54外侧且与壳体5的第二端壁54相连。第一安装支架7和第二安装支架8均设有安装通孔，例如可以通过螺钉等贯通该安装通孔而将第一安装支架7和第二安装支架8紧固安装于服务器安装架或服务器货架等。作为示例，安装通孔包括长孔，由此能够方便地调整电源分配单元的安装位置。
上述构成的电源分配单元可以安装于货架。作为一例，货架可以包括多个立柱以及固定在立柱间的多个层板，立柱可以垂向设置，层板沿垂直于立柱的平面延伸，层板的边缘可以固定在多个立柱上，层板上方可以用于放置多种用电设备，例如服务器等。如上所述的电源分配单元以其长度方向与层板的延伸方向一致的方式安装于层板，例如安装于层面的侧面。由此，能够为放置于层板上的服务器等用电设备分配电源，并能够针对各服务器的通电与否进行各自独立的控制。
