    • A fiber retention device is provided for retention of fibers such as optical fibers, tubing, cables, buffer tubes and other elongate objects. The retention device includes, generally, a mounting retainer and a resilient sleeve. The mounting retainer is formed of a resilient material and defines one or more generally U-shaped support channels. The resilient sleeve is positioned in the U-shaped support channel and defines at least one expandable passageway for receiving a fiber therein. The passageway diameter is less than the fiber diameter in a pre-load orientation or relaxed condition prior to inserting the fiber into the passageway. The support channel selectively includes a plurality of tabs for locating the sleeve therein including tabs on a bottom wall for resisting relative horizontal movement and tabs on a side wall for resisting relative vertical movement of the sleeve within the channel. The sleeve is positively located by the channel, and the fiber is retained and strain relieved by the elastomer sleeve. A mounting flange is provided for coupling a plurality of mounting retainers in a coupled orientation as desired.
    • 提供纤维保持装置用于保持诸如光纤,管道,电缆,缓冲管和其它细长物体之类的纤维。 保持装置通常包括安装保持器和弹性套筒。 安装保持器由弹性材料形成并且限定一个或多个大体上U形的支撑通道。 弹性套筒定位在U形支撑通道中,并且限定了用于在其中容纳纤维的至少一个可扩张通道。 在将纤维插入通道之前,通道直径小于预加载取向或松弛状态下的纤维直径。 支撑通道选择性地包括多个用于将套筒定位在其中的突出部,其中包括用于抵抗相对水平运动的底壁上的突片和侧壁上的突片,以抵抗套管在通道内的相对垂直运动。 套筒由通道确定地定位,并且纤维被弹性体套筒保持和应变释放。 提供了安装法兰,用于根据需要以联接方向联接多个安装保持器。

    • A cable closure is provided which adapted to accommodate different size cables and different splices. The closure includes end plates designed to receive various size cables without requiring modification during field use. The end plates are interchangeable with stainless steel and injection molded closure shells. A sealant is provided which allows multiple re-entries into closure shell. Bolts are assembled on the exterior of the closure shell to eliminate potential misalignments between the bolts and closure shell holes. Washers are used within the end plates to seal holes not used for storing cables. A cutter is provided which cuts the washers in one 360° rotation thus eliminating weak points in the washer due to multiple cuts. Alternately a plug is provided for the end plate holes which are adaptable to several size holes to reduce the number of plugs required.
    • 提供了一种电缆封盖,适用于适应不同尺寸的电缆和不同的接头。 封闭件包括端板,设计用于接收各种尺寸的电缆,而不需要在现场使用期间进行修改。 端板可与不锈钢和注塑封闭壳互换。 提供密封剂,其允许多次重新进入封闭壳体。 螺栓被组装在封闭壳体的外部,以消除螺栓和封闭壳体孔之间的潜在的未对准。 在端板中使用垫圈来密封不用于存储电缆的孔。 提供了一种切割器,其以一个360°的旋转方式切割垫圈,从而消除了由于多次切割而导致的垫圈中的弱点。 或者,为端板孔设置插头,该插头可适应几个尺寸的孔以减少所需的插头数量。
