技术领域
本发明涉及连接器技术领域，更具体地说，涉及一种FCT(Functional Circuit Test，功能测试)测试治具的连接结构。此外，本发明还涉及一种FCT测试治具。
背景技术
随着当前计算机的高速发展，服务器的用量在急剧上升。服务器的研发和迭代更新就显得尤为重要，每一台服务器主板在出厂前都要经过重重测试验证，诸多测试验证又要依据许多测试工具，FCT治具便是其中很重要的一个测试工具。FCT即功能测试，模拟服务器运行环境。
同时，随着用户对服务器功能要求越来越多，并且对空间利用率要求越来越高，使得主板整体布局非常紧凑。因此服务器主板做的越来越复杂，包含的元器件越来越密集，导致主板连接器做的越来越小。
目前新一代主板上大量使用的I2C接口均是4PIN的、PIN脚间距为1毫米的连接器，并且板端连接器是刀片式接口，而线端连接器尺寸很小，导致插拔操作较为困难，降低了工作效率。
综上所述，如何提供一种可实现快速插拔的连接器，是目前本领域技术人员亟待解决的问题。
发明内容
有鉴于此，本发明的目的是提供一种FCT测试治具的连接结构，该连 接结构方便操作人员或操作器械实现线材与主板的连接，避免因为线材、主板的连接器过小导致不方便插拔的情况。
本发明的另一目的是提供一种包括上述连接结构的FCT测试治具。
为了实现上述目的，本发明提供如下技术方案：

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的核心是提供一种FCT测试治具的连接结构，该连接结构方便操作人员或操作器械实现线材与主板的连接，避免因为线材、主板的连接器过小导致不方便插拔的情况。
本发明的另一核心是提供一种包括上述连接结构的FCT测试治具。
如图1所示，本申请提供的一种FCT测试治具的连接结构，主要用于实现线材与主板的连接。上述连接结构主要包括：固定部1和连接部2。
其中，固定部1用于连接线材3，连接部2用于连接主板板端连接器。固定部1与连接部2连接，用于导通线材3与主板板端连接器；固定部1或连接部2具有操作部，所述操作部为块状结构，用于连接插拔操作控制器且方便操作者持握。
需要说明的是，固定部1可以与线材固定连接，或为可拆卸的连接，可以根据实际使用目的进行调整。连接部2的作用是形成连接主板板端连接器的端部，端部可以为探针或金手指等，用于连接主板板端连接器，当然，另一端需要连接线材，从而形成线材到主板的连通。
固定部1或者连接部2上设置有操作部，操作部为硬质的、具有较大体积的块状结构，实际操作时，插拔操作控制器或机械手可以直接持握操 作部，方便向主板进行插拔。或者操作人员可以直接用手控制该操作部。由于操作部为块状的硬质结构，无论机械手或者人工操作都能够更好的持握和插拔，避免了由于线材端部较小，无法实现在密集的主板上进行插板的问题。
在上述实施例的基础之上，固定部1包括固定块11和用于固定探针针套14的针筒12，探针针套14内部设置有探针15，探针15伸出于固定块11的一端用于连接线材3，且探针15的另一端用于连通连接部2。
固定块11通过螺钉或其他固定件连接针筒12，针筒12内部用于固定探针针套14，探针针套14的内部安装探针15，探针针套14可以过盈配合设置在针筒12内，或者以固定件的形式安装在针筒12内。
探针针套14的作用是安装探针15，探针15连接线材以及连接部2上用于连接主板板端连接的部分。
连接部2上设置有类似于线材端部的结构，该结构可以为探针结构，或者为金手指结构，以便直接连接主板板端连接器，由于主板板端连接器的类型多样，该结构的类型可以根据实际需要连接的主板类型进行调整。
在上述实施例的基础之上，固定块11设置有用于固定连接针床的固定螺孔；
连接部2与针筒12通过弹性件16连接，以使连接部2受插拔操作控制器控制移动时，能够使固定部1具有缓冲效果。
针床为固定位置的结构，方便将固定块进行定位，由于固定块的作用是将整体结构固定在FCT治具上，因此针床与FCT治具相对固定。
固定块11上除了设置固定螺孔以外，还可以通过其他固定结构连接针床。
设置弹性件16的目的是实现缓冲效果，连接部2具体可以为缓冲导向块13，缓冲导向块13和针筒12配合下压的过程中，缓冲导向块13首先接 触主板板端连接器，但位置可能需要调整或与下压轨迹具有横向偏差，此时弹性件16能够为针筒12提供缓冲效果，避免因偏差等原因导致插拔的不准确、以及损坏主板板端连接器。
需要说明的是，虽然连接部2与针筒12通过弹性件16连接，使得连接部2与针筒12具有一定的活动空间，但是在活动范围内，探针15探针始终与连接部2上用于连接主板板端连接的部分保持连接。可以理解为该部分的面积较大，在连接部2在弹性件16形成的活动范围内，探针15始终在该部分的范围内，与该部分保持连接。
使用时，可以将探针15的一端通过焊接等方式连接线材，将装有探针15的探针针套14固定于固定块11中，并使探针15的下部与缓冲导向块13上用于连接主板的部分连接。然后，通过插拔操作控制器持握缓冲导向块13，并向主板板端连接器进行插入。由于缓冲导向块13具有硬质结构，便于实现插拔的持握，能够满足线材与主板连接的稳定性。
可选的，上述弹性件16的个数可以为偶数个，并以对称的形式设置在缓冲导向块13上，以保证结构的平衡性和稳定性，同时还能够避免因为误差导致的损坏的情况。同时，缓冲导向块底部的结构形状可以和线端连接器形状一样，下压导入过程起到导向作用。
可选的，上述连接部2上的用于连接主板的部分可以为探针15，探针针套14表面需要进行绝缘处理，并使用热缩管套在针套上面，避免因针套之间距离过小而导致短路现象发生。
关于上述探针15的设置，如果选用较大的探针15，直接后果就是探针针套14之间相互紧贴，导致短路现象。由于主板板端连接器多采用刀片式结构，因此探针的选择也很重要，其中，四爪探针可以依靠其V字型的结构卡紧主板板端连接器。
本实施例中，固定块11、针筒12或缓冲导向块13均可以为块状的硬 质结构，并具有操作部，以便插拔操作控制器或操作人员进行直接控制。
在第一个实施例的基础之上，固定部1夹紧套接于线材3外周，连接部2与固定部1的一侧夹紧并固定，用于将由固定部1的一侧伸出的线材3夹紧于其中，线材3绕过连接部2、并连接于连接部2的另一侧的FCT接口上，FCT接口用于连接主板板端连接器。
固定部1套接在线材3的外周，假设固定部1所在平面为水平面，那么固定部1目的是对线材3进行水平面内的移动限位。
连接部2与固定部1夹紧固定，将固定部1一侧伸出的线材3夹紧于其中，从而在纵向方向上固定了线材3。被夹紧的线材3的自由端与连接部2的FCT接口连接，连接部2可以为PCB电路板，或者为其他具有电路的结构，连接部2上的FCT接口与FCT治具探测接口连接。
在上述实施例的基础之上，固定部1包括若干个叠加设置的第一PCB板21，如图2所示，线材3伸入第一PCB板21的钻孔中，连接部2包括第二PCB板22，线材3焊接到FCT接口。
可以将一定厚度的第一PCB板21的中间钻孔，钻孔的形状和尺寸与线材3的形状和尺寸相同，将线材3插入第一PCB板21中，从而限制线材在第一PCB板21所在平面内的运动。然后，控制第二PCB板22将线材3压紧于第一PCB板21上，从而限制线材在上述钻孔中的移动，起到固定的作用。此时被压制的线材3的一端(即靠近第二PCB板22的一端)可以连接第二PCB板上的FCT探测接口。可选的，在第二PCB板22上设置有电路连接FCT探测接口的端口，该端口可以直接连接主板板端连接器。
一个较为可靠的实施例中，按照以上方案，通过三块1毫米厚度的第一PCB板21限制线材3的X和Y方向的移动，通过一块同样厚度的第二PCB板22限制线材3的Z方向的移动，从而起到了固定连接器的作用。
由于通过第一PCB板21和第二PCB板22将线材3进行了固定，因此 若此时拉扯线材3，则第一PCB板21和第二PCB板22可以提供插拔时所需要的力，保证插拔的稳定性。
本实施例中，第一PCB板21和第二PCB板22均可以为块状的硬质结构，并具有操作部，其中，操作部可以为PCB板的主体结构，以便插拔操作控制器或操作人员进行直接控制。
在第一个实施例的基础之上，如图3所示，固定部1包括用于连接线材3端口的连接端口，连接部2设置有凹槽33，凹槽33中设置有用于连接主板板端连接器的金手指34，连接端口与金手指34导通连接。
具体地，固定部1为第一转接板31，第一转接板31设置有连接端口，可以直接连接常见的线材端口。连接部2为第二转接板32，第一转接板31与第二转接板32通过电路连接，或者具有导电结构。
在第二转接板32上设置有用于插入金手指34的凹槽33，利用金手指34实现与主板的连接，以及金手指34与第一转接板31电路连接。
在上述实施例的基础之上，凹槽33为纵向凹槽，金手指34竖直设置在凹槽33中，以便凹槽33与主板板端连接器的板端接口的连接。
在第二转接板32上设置有用于插入金手指34的凹槽33，普通的金手指通常贴附在表面上，或者横向的贴附在凹槽的底面。但本实施例中的金手指34竖直设置在凹槽33中，便于与刀片式的板端连接器配合连接。
在上述实施例的基础之上，固定部1与连接部2焊接连接；和/或连接部上设置有用于与主板板端连接器或针床固定的安装孔。
第一转接板31与第二转接板32可以为焊接连接、粘接连接或其他固定连接，二者形成固定式的连接，有利于保证线材3的连接端与金手指34的稳定连接。
安装孔的位置可以避开金手指34与第一转接板31电路连接的位置，安装孔可以设置有螺纹或者其他安装件，以便实现安装。
可选的，凹槽33为铣槽，凹槽33与主板板端连接器的刀片结构对应。
本实施例中，第一转接板31与第二转接板32均可以为块状的硬质结构，并具有操作部，其中，操作部可以为第一转接板31与第二转接板32的主体结构，以便插拔操作控制器或操作人员进行直接控制。
除了上述各个实施例中所提供的FCT测试治具的连接结构，本发明还提供一种包括上述实施例公开的连接结构的FCT测试治具，FCT测试治具包括线材和连接结构，其中，线材可以连接固定部，固定部与连接部连接，连接部与主板连接。
该FCT测试治具的其他各部分的结构请参考现有技术，本文不再赘述。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
以上对本发明所提供的FCT测试治具以及FCT测试治具的连接结构进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
