[0028] In an optional embodiment: the number of tensile-resistant parts is set to three groups, and the tensile-resistant parts include a strip 23 fixedly connected to the outer side of the inner tube sleeve 20 in the length direction, and the strip 23 has a plurality of U-shaped plug-in frames 22 on the side away from the inner tube sleeve 20, and elastic blocks 25 are fixedly connected to both sides of the inner wall of the plug-in frame 22. The opposite end faces of the two elastic blocks 25 are arranged in an arc shape, and gaps are formed at the opposite ends of the two elastic blocks 25. When the wire body 21 is wound on the outer surface of the inner tube sleeve 20, one end of the wire body 21 passes through the gaps in the inner sides of the plurality of plug-in frames 22 in turn, and the wire body 21 spirally wound on the inner tube sleeve 20 provides a certain tensile resistance, and then the elastic blocks 25 on the plurality of plug-in frames 22 evenly apply force to the wire body 21 when being pulled, so that the wire body 21 has good tensile resistance.

[0034] When it is necessary to remove the wire assembly 2, it is only necessary to first pull out the arc-shaped limit sleeve 4 connected to the wire assembly 2 to the outside of the protective layer 1, and then pull the wire assembly 2 away from the optical fiber assembly 3, so that the insertion frame 22 is disengaged from the first slot 201 and the second slot 202, and then the wire assembly 2 is pulled out from the protective layer 1. Therefore, through this application, it is convenient to remove the wire assembly 2 from the protective layer 1, and the stability and resistance of the wire assembly 2 connected inside are maintained.
