摘要： A bracket for an electronic card that is inserted into a slot of a chassis. The chassis has a pair of opposing walls with guide channels that guide the card into a motherboard. The bracket includes a pair of low friction guide rails that slide along the guide channels. Attached to the guide rails are a pair of grommet dampers which are pressed between the edges of the card and the guide channels when the card is inserted into the chassis. The grommets dampen any shock or vibrational load that is transferred from the chassis to the card. The bracket also has a pair of spring clips that are attached to the card and pressed into the guide channels to provide an electrical path between the card and the chassis. The electrical path discharges electrostatic charges on the card and provides a ground path for any electromagnetic fields generated or received by the card. The bracket further includes a lever pivotally connected to one of the guide rails. The lever has a latch that can engage the chassis to secure the card in the installed position. The lever has rounded edges and a width no greater than the thickness of the card to allow cooling air to readily flow past the card. The pivot point of the lever is located above the card so that the bracket may be assembled to cards of various lengths.

摘要翻译： 用于插入机箱槽中的电子卡的支架。 底盘具有一对相对的壁，其具有将卡引导到母板中的引导通道。 支架包括一对沿导向槽滑动的低摩擦导轨。 连接到导轨上的是一对索环阻尼器，当卡插入到底盘中时，它们在卡的边缘和引导通道之间被按压。 垫圈会抑制从机箱转移到卡上的任何冲击或振动负载。 支架还具有一对弹簧夹，其连接到卡并压入引导通道中以在卡和底盘之间提供电路径。 电路放电卡片上的静电电荷，并为卡产生或接收的任何电磁场提供接地路径。 支架还包括可枢转地连接到一个导轨的杆。 杠杆具有能够接合底盘以将卡固定在安装位置的闩锁。 杠杆具有圆形边缘，宽度不大于卡的厚度，以允许冷却空气容易地流过卡。 杠杆的枢转点位于卡的上方，使得支架可以组装成各种长度的卡。
