    • The present invention is a cell bypass switch particularly designed for aerospace applications. The cell bypass switch can sense a battery cell failure and automatically opens an alternate path around the failed cell, bypassing the failure and allowing the remainder of the battery system to continue its function. The cell bypass switch is designed to be placed in parallel with the battery cell it protects. The present invention includes two electro-mechanical actuator assemblies which are mounted on the top end of the housing for operating two plungers respectively. Each of the electro-mechanical actuator assembly includes two spool halves which are held together by a tight winding of a restraining wire that terminates in a bridge wire connecting two electrical terminals of the electro-mechanical actuator. Each spool, by virtue of the restraining wire winding, can restrain a spring loaded plunger. However, when sufficient electrical current is passed through the terminals and the bridge wire, the bridge wire will heat up and break under the applied tension load. This causes the restraining wire to unwind, separating the spool halves and releasing the plunger.
    • 本发明是特别设计用于航空应用的电池旁路开关。 电池旁路开关可以感测电池单元故障,并自动打开故障单元周围的备用路径,绕过故障并允许电池系统的其余部分继续运行。 电池旁路开关设计成与其保护的电池单元平行放置。 本发明包括两个机电致动器组件,其安装在壳体的顶端,用于分别操作两个柱塞。 每个机电致动器组件包括两个卷轴半部,其通过限制线的紧密绕组保持在一起,该限制线终止于连接机电致动器的两个电端子的桥接线。 通过限制线缠绕的每个线轴可以限制弹簧加载的柱塞。 然而,当足够的电流通过端子和桥接线时,桥接线将在施加的张力负载下加热和断裂。 这使得限制线松开,分离出卷轴半部并释放柱塞。

    • A terminus for an optical fiber cable (10) has a ferrule (22) with an endwall portion (24) including an axial opening (26) for receiving a glass fiber core. A ferrule central portion (28) is larger in cross-section than endwall portion (24) and the opposite end portion (32) is still larger. In assembly, the fiber jacket (16) or strain relief is peeled back over an underlying sleeve (34) and crimped within the opposite end portion (32). The central ferrule portion (28) has an internal sleeve (40) fitted over a section of the optical fiber with buffer tubing (14) and the ferrule is crimped in place. The fiber outer end portion consists of just the bare glass core (12) received within endwall opening (26).
    • 用于光纤电缆(10)的端子具有带有端壁部分(24)的套圈(22),该端壁部分(24)包括用于容纳玻璃纤维芯的轴向开口(26)。 套圈中心部分(28)的横截面比端壁部分(24)大,并且相对的端部部分(32)更大。 在组装中,将纤维套(16)或应变消除物在下面的套筒(34)上被剥离并卷曲在相对端部(32)内。 中心套圈部分(28)具有内部套筒(40),该内部套筒(40)安装在具有缓冲管(14)的光纤的一部分上,并且将套圈压接就位。 光纤外端部仅由容纳在端壁开口(26)内的裸玻璃芯(12)组成。
