Examples

The present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the optical-electrical hybrid cable for a data center includes an optical unit 1, a conductive wire 2 and a sheath 3, the optical unit is a single or multiple optical fibers, and the optical unit is disposed in the center of the sheath; the two conducting wires are symmetrically arranged on two sides of the optical unit by taking the axis of the mixed cable as a center, the conducting wires are made of copper wire extrusion molding insulating materials, the strength of the conducting wires is higher than that of optical fibers, and a certain compression-resistant effect can be achieved; the sheath extrusion molding is in the outside of light unit and conductor wire, and the cross-section is flat ellipse, and the sheath that the sheath minor axis both ends correspond inwards caves in, forms depressed part 4.

Further, a cavity 5 is arranged in the center of the sheath, the cross section of the cavity is oval, the long axis of the cavity is overlapped with the short axis of the sheath, and the light unit is arranged in the cavity. In order to improve the moisture resistance of the hybrid cable, water-blocking yarns or water-blocking factice is arranged in the gap between the cavity and the optical unit, and the water-blocking yarns are selected in the embodiment in consideration of the fact that the hybrid cable is mainly used in a data center machine room and the water-blocking factice is not easy to clear and is not beneficial to stripping wires.

Furthermore, an M-shaped reinforcing piece 6 is arranged between the optical unit and the conducting wire, the open end of the M-shaped reinforcing piece points to the optical unit, the closed end points to the conducting wire, the M-shaped reinforcing piece is vertically symmetrical by taking the long axis of the sheath as a symmetrical line, namely the M-shaped reinforcing piece is vertically symmetrical and horizontally by taking the axis of the mixed cable, in practical use, the length of the end point connecting line of the closed end of the M-shaped reinforcing piece is less than or equal to that of the end point connecting line of the open end of the M-shaped reinforcing piece is less than or equal to that of the long axis of the cavity, in the embodiment, the length of the end point connecting line of the open end of the M-shaped reinforcing piece is equal to that of the long axis of the cavity, and the open ends of the two M-shaped reinforcing pieces are abutted face to face and cover the outside of the cavity.

When the M-shaped reinforcing piece is stressed in the vertical direction, namely the upper section and the lower section are easily stressed by external pressure, when the M-shaped reinforcing piece is stressed, the open ends formed by the upper side and the lower side of the M-shaped reinforcing piece and the oval cavity contract together, so that external force is resisted and buffered, the optical fiber is prevented from being damaged, and an elastic material with certain hardness, such as MDPE or HDPE and the like, is selected for the M-shaped reinforcing piece to better play a supporting and buffering role.

For the convenience of wire stripping, as shown in fig. 1 and 2, the upper surface and the lower surface of the sheath are symmetrically provided with first tearing openings 7 along the axial direction, the first tearing openings are distributed discontinuously along the axial direction, the M-shaped reinforcing member is provided with second tearing openings 8 along the axial direction, the second tearing openings vertically penetrate through the M-shaped reinforcing member, in the embodiment, the concentration degree of the second tearing openings is far higher than that of the first tearing openings, and the sheath and the M-shaped reinforcing member can be conveniently stripped through the matching of the first tearing openings and the second tearing openings to expose the optical fibers.

The invention is mainly applied indoors, so the sheath is made of flame-retardant polyolefin material.

In practical use, in order to standardize wiring and save space, a plurality of optical cables are usually bundled together, and when the optical cable bundling device is used for bundling, due to the arrangement of the M-shaped reinforcing piece and the oval cavity, under the matching of the M-shaped reinforcing piece and the oval cavity, the compression resistance and the buffering performance are good, and the optical fibers cannot be damaged.

Furthermore, since the recesses of the sheath are easily mouldable and difficult to remove, the recesses may be made of a material having a bacteriostatic effect, such as a material doped with Ag or TiO, during extrusion₂The polyolefin material of the particles, whereby molding of the depressions can be effectively suppressed.

In the implementation of this embodiment, the recessed portion of the sheath is manually pulled upward or downward along the first tearing opening, the sheath is peeled to expose the "M" shaped reinforcing member, and then the recessed portion is pulled upward or downward along the second tearing opening of the "M" shaped reinforcing member until the optical fiber is exposed.
