The communication cable 42 comprises a core 43 and a shield 44, the end of the shield 44 being secured to the connector 1 of the communication cable 42, and the tip of the core 43 extending through the communication cable 42 into the communication plug 38 at the connector 1. The protective layer 44 includes an outer sheath and reinforcing ribs.

Further, in a preferred embodiment, the communication cable 42 is an optical cable and the core 43 is an optical fiber. Alternatively, the communication cable 42 can also be other types or materials of communication cables 42, such as, but not limited to, a communication wire of a metal core 43, etc., and the specific type of the communication cable 42 should not be construed as a limitation to the present invention.

Referring to fig. 1, the communication cable 42 connector 1 includes a first housing 2, a second housing 3, and an intermediate housing 24. The first housing 2 is adapted to hold a communication plug 38, the second housing 3 is adapted to hold an end of a shielding 44, and the intermediate housing 24 is located between and connects the first housing 2 and the second housing 3, respectively. The middle housing 24 is integrally connected to the first housing 2 and the second housing 3, and may be an adhesive connection in other embodiments.

Further, as a preferred embodiment, the connector 1 of the communication cable 42 further has a wire accommodating space 36 penetrating the first housing 2, the intermediate housing 24 and the second housing 3.

The intermediate housing 24 can be extended and retracted along the longitudinal extension of the wire accommodating space 36 to adjust the distance between the first housing 2 and the second housing 3 in both directions. It is noted that the bidirectional adjustment means that the distance between the first housing 2 and the second housing 3 can be either increased or decreased.

Referring to fig. 1 and 2, the middle shell 24 is a plurality of layered structures 27 stacked along the length extension direction of the line accommodating space 36, and the distance between at least a part of the adjacent layered structures 27 can be adjusted in both directions. In other preferred embodiments, the distance between all adjacent layers of the intermediate housing 24 can be adjusted bi-directionally.

When the distance between the first shell 2 and the second shell 3 needs to be increased, the first shell 2 and the second shell 3 are pulled to move away from each other, and the distance between at least one part of adjacent layer structures 27 is increased; when it is desired to reduce the distance between the first housing 2 and the second housing 3, the first housing 2 and the second housing 3 are compressed to move closer together, reducing the distance between at least a portion of the adjacent layer structures 27.

It should be noted that in the process of increasing or decreasing the distance between the first casing 2 and the second casing 3, the multi-layer structure 27 of the intermediate casing 24 moves substantially along the length direction of the line-containing space 36, and mutual rotation does not occur, so that the strength of the structure can be greatly improved.
