    • A locking cable for use in an antitheft device adapted to give warning in response to a change in a photo signal transmitted through an optical fiber longitudinally extending through the locking cable. The locking cable comprises a core portion including the optical fiber, a reinforcing layer concentrically disposed around the core portion and including at least one electric conductor and a plurality of reinforcing members, and a flexible hollow protective member as an outermost layer covering the electric conductor and reinforcing members in contact with the protective member. If required, a further reinforcing layer may be interposed between the core portion and the first-mentioned reinforcing member, which includes a plurality of second reinforcing members. A holder holding an end of the optical fiber and a photoelectric element in face-to-face relation to each other is axially movably arranged within a plug connected to an end of the locking cable. Space is defined between the plug and the holder, through which the electric conductor axially movably extends.
    • 一种用于防盗装置的锁定电缆,适于响应于通过纵向延伸穿过锁定电缆的光纤传输的光信号的变化而发出警告。 锁定电缆包括包括光纤的芯部分,同心地设置在芯部周围并且包括至少一个电导体和多个加强构件的增强层,以及作为覆盖电导体的最外层的柔性中空保护构件,以及 加强构件与保护构件接触。 如果需要,可以在芯部和第一加强构件之间插入另外的加强层,该加强构件包括多个第二加强构件。 保持光纤的端部和彼此面对面的光电元件的保持器被轴向移动地布置在连接到锁定电缆的端部的插头内。 空间被限定在插头和支架之间,电导体通过支架轴向可移动地延伸。
