技术领域
本发明属于服务器技术领域，特别涉及一种免工具拆装的PCI-e模块。
背景技术
PCI-Express(peripheral component interconnect express)是一种高速串行计算机扩展总线标准，简称"PCI-e")用于计算机或通讯平台的外围组件的互连，普遍应用于服务器等产品中。为增加设备的可维护性，以及装配需要，PCI-e卡可支持插拔，服务器(Server)或储存式服务器(Storage Server)有时会采用直立式PCI-e适配卡，除了适配卡本身金手指需要与适配卡的插槽固定之外，也需固定住适配卡的I/O铁片以免震动时信号不稳；现有的PCI-e卡在服务器中的固定方式大多为螺丝固定，即PCI-e卡直接插入至PCI-e接口中，然后将PCIe卡挡片通过螺钉安装在机箱上，在组装或拆卸，需借助螺丝刀、螺丝等各种工具，操作起来存在诸多不便。

具体实施方式
下面结合附图1-9，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。
在本发明的描述中，需要理解的是，术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
一种免工具拆装的PCI-e模块，包括机箱1、后窗2、介面卡3、固定钢片4，所述机箱1底部设有PCI-e连接器(图中未示出)，所述介面卡3下端通过金手指插接在PCI-e连接器上；所述介面卡3一侧设有I/O铁片31，所述I/O铁片31一侧设有连接板34，连接板34与介面卡3连接，所述介面卡3上部一侧设有扣板33；所述机箱1一端设有后窗2，所述后窗2上设有若干均匀布置的隔槽27，所述介面卡3安装在隔槽27一侧，介面卡3的扣板33搭接在后窗2的上部；所述后窗2一侧设有固定钢片4，所 述固定钢片4包括垂直部41和水平部42，所述水平部42上设有夹持槽49，所述垂直部41设置在水平部42的两端，垂直部41下端设有通孔43，铆钉21穿过通孔43将垂直部41铆合在后窗2侧壁上，固定钢片4旋转定位时，后窗2上壁及扣板33安装在夹持槽49内部；利用水平部42压制适配卡I/O铁片使其固定，避免了PCI-e适配卡振动，保证了PCI-e适配卡信号的稳定性，实现了PCI-e适配卡的免工具插拔，提高了PCI-e适配卡的拆装效率；PCI-e适配卡拆卸时，将固定钢片4绕铆钉21旋转，使固定钢片4与I/O铁片31的扣板33分离，将PCI-e适配卡的金手指从PCI-e连接器上拔下，完成PCI-e适配卡的拆卸。
在本实施例中，所述后窗2上壁上部设有若干定位柱23，所述扣板33一侧设有与定位柱23卡合的定位槽35，定位柱23和定位槽35不仅保证了PCI-e适配卡安装的准确性，同时限制了PCI-e适配卡在前后方向的移动，保证了PCI-e适配卡安装的稳定性。
在本实施例中，所述隔槽27下部一侧设有第一围板24，所述第一围板24两端与后窗2连接，第一围板24与后窗2间形成插槽25，所述I/O铁片31下端设有插头32，所述插头32插接在插槽25内部，插槽25避免了PCI-e适配卡的晃动，进一步保证了PCI-e适配卡安装的稳定性。
在本实施例中，所述水平部42与扣板33、后窗2上壁均过盈配合，保证了固定钢片4的夹持效果。
在本实施例中，所述水平部42上部一侧设有若干弹性凸包45，所述弹性凸包45向扣板33一侧凸起，弹性凸包45增强了水平部42与扣板33间的夹持力，保证了I/O铁片31安装的稳定性。
在本实施例中，所述夹持槽49的上壁为弧形板状结构，且夹持槽49的上壁中部向扣板33一侧凸起，增强了水平部42对扣板33及后窗2的夹持效果，同时，夹持槽49的上壁前部翘起，便于扣板33和后窗2上壁快速准确地插接在水平部42内部。
在本实施例中，所述垂直部41一端设有止挡臂44，所述止挡臂44一侧设有止挡柱22，所述止挡柱22固定地安装在后窗2侧壁上，止挡柱22避免了固定钢片4过旋转。
在本实施例中，所述垂直部41一侧设有止挡片47，所述止挡片47通过铆钉21铆合在垂直部41上，所述止挡片47前端伸出垂直部41，止挡片47后端与垂直部41后部平齐，止挡片47保证了固定钢片4旋转的精确性，保证了PCI-e适配卡固定的效果；所述止挡片47上下两侧设有卡钩48，所述后窗2侧壁上设有与卡钩48配合的卡槽26，水平部42将扣板33压紧后，卡钩48插接在卡槽26内部，避免了固定钢片4转动；PCI-e适配卡拆卸时，用手将止挡片47向中间掰动，使卡钩48与卡槽26分离，然后转动固定钢片4，将PCI-e适配卡拆下。
在本实施例中，所述卡钩48截面为直角三角形，且卡钩48的直角边靠近止挡片47的前端，斜边减小了固定钢片4旋转定位时后窗2对卡钩48的阻力，便于固定钢片4的定位；直角边避免了固定钢片4定位后卡钩48与卡槽26分离，保证了固定钢片4定位的稳定性。
在本实施例中，所述垂直部41一侧一体成型有第二围板46，所述止挡片47安装于第二围板46与垂直部41间形成的空槽内部，第二围板46限制了止挡片47的活动范围，避免了PCI-e适配卡拆卸时用力过大造成止挡片47变形。
以上内容仅仅是对本发明的结构所作的举例和说明，所属本技术领域的技术人员对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，只要不偏离发明的结构或者超越本权利要求书所定义的范围，均应属于本发明的保护范围。
