    • A heat recoverable coupling assembly for substrates having a relatively rigid outer wall, which includes a connector body and a driver member made from a band of heat recoverable material. The connector body includes a mating area for engaging a mating area on the rigid wall of the substrate. The connector body is positioned inside or outside the substrate and the driver member is positioned around the outside member. The driver member has an unrecovered transverse dimension larger than the outside member and a recovered transverse dimension smaller than the outside member. The driver member is positioned around the outside member over at least part of the mating areas. Upon heating the driver member to its recovery temperature, the driver member deforms the outside member and itself plastically deforms to a shape suitable for retaining the substrate and the connector body together. The driver member is made from heat recoverable engineering plastics.
    • 一种用于具有相对刚性外壁的基板的可热回收联接组件,其包括连接器主体和由可热回收材料带制成的驱动件。 连接器主体包括用于接合基板的刚性壁上的配合区域的配合区域。 连接器主体位于基板的内部或外部,并且驱动器构件围绕外部构件定位。 驾驶员构件具有比外部构件大的未收缩的横向尺寸和小于外部构件的恢复的横向尺寸。 驾驶员构件位于外部构件周围的至少一部分配合区域上。 在将驱动器部件加热至其恢复温度时,驱动部件使外部部件变形,并且其本身塑性变形为适于将基板和连接器主体保持在一起的形状。 驾驶员由热回收工程塑料制成。

    • A hand tool formed by a body member 10B and a torque sleeve member 12S is employed to tighten a connector nut 14N at the end of an electrical cable 14C onto a cable terminal post 14P. The body is elongated having a long axis with a socket wrench 10W at one end and a handle 10H at the other end. A cable channel 10C extends along the long axis from the wrench end to the handle end for receiving the cable during installation. The inside surface of the wrench has side walls 10SW for capturing the connector nut. The outside surface of the wrench has a slight taper toward the wrench end of the body, and the inside surface of the sleeve has a generally matching taper. The sleeve is slide mounted over the wrench and the connector nut for establishing a pre-load hoop tension in the sleeve against the wrench which establishes a pre-load compression in the wrench against the connector nut. The engagement of the matching tapered surfaces causes the pre-load hoop tension to increase as the sleeve is slid over the wrench. The tapered surface engagement produces a working load hoop tension in the sleeve as the nut is tightened against the terminal post, which produces a working load compression in the wrench against the nut. The working load hoop tension has a critical value above which the tensile expansion of the sleeve permits the side walls of the wrench to slip around the nut for limiting the torque of the nut against the terminal post.
    • 使用由本体构件10B和扭矩套筒构件12S形成的手形工具将电缆14C的端部处的连接器螺母14N紧固到电缆端子柱14P上。 主体细长,具有长轴,一端具有一个套筒扳手10W,另一端具有手柄10H。 电缆通道10C沿着长轴线从扳手端延伸到手柄端,用于在安装期间接收电缆。 扳手的内表面具有用于捕获连接器螺母的侧壁10SW。 扳手的外表面朝向主体的扳手端部具有微小的锥度,并且套筒的内表面具有大体上匹配的锥度。 套筒滑动安装在扳手和连接器螺母上,用于在套筒中相对于扳手建立预加载箍张力,该扳手在扳手中建立对连接器螺母的预加载压缩。 匹配的锥形表面的接合导致预先加载的环向张力随着套筒在扳手上滑动而增加。 当螺母紧靠端子柱时,锥形表面接合在套筒中产生工作负载环向张力,这在扳手中产生工作负载压靠在螺母上。 工作负载环向张力具有临界值,在该临界值之上,套筒的拉伸膨胀允许扳手的侧壁在螺母周围滑动,以限制螺母抵靠端子柱的扭矩。
