a wire cavity is arranged in the core wire 200, an optical fiber wire 300 is arranged in the wire cavity, and the optical fiber wire 300 is an optical fiber bundle formed by a single optical fiber or a plurality of optical fibers;
the sheath 100 is elliptical in the radial section of the optical cable, and the short axis direction is up and down, and the long axis direction is left and right;
the special-shaped buffer strip 400 is symmetrically arranged on the upper side and the lower side of the core wire 200, and consists of two parts, namely a buffer section 401 and a support section 402, wherein the buffer section 401 is arched outwards and does not contact the core wire 200, the support section 402 is arranged at two ends of the buffer section 401 and is propped inwards in the clamping groove 201, and the special-shaped buffer strip 400 is stably arranged relative to the core wire 200 in the mode;
the flat optical cable is generally stressed on the upper and lower sides, and has weaker compression resistance compared with a round optical cable, and has the main advantages of compact structure, easy arrangement, easy shielding and difficult winding and knotting.
Further, the method comprises the steps of,
the middle part of the buffer section 401 of the special-shaped buffer strip 400 is recessed towards the axis of the optical cable to form a notch 4011, and the inner side of the notch 4011 is not contacted and abutted with the core wire 200;
the setting of the notch 4011 can further enhance the buffering effect of the special-shaped buffer bar 400 on vibration, because the acting force of vibration collision is usually smaller, under the condition of small acting force, a simple arch structure can only play a role in buffering once, after the notch 4011 is set, the stress deformation on two sides of the notch 4011 drives the notch 4011 to deform, the multi-deformation process is matched, and a very small amount of acting force is continuously acted on the outer surface of the core wire 200, so that a better anti-vibration buffering effect is formed, and the damage of the optical fiber 300 caused by equipment vibration can be better avoided when the special-shaped buffer bar is used for wiring of industrial equipment;
as shown in fig. 2, when the optical cable of the present invention is subjected to a vibration action, the buffer sections 401 on two sides of the notch 4011 of the special-shaped buffer strip 400 are firstly stressed and inwardly generate displacement deformation, at this time, the ends of the buffer sections 401 of the special-shaped buffer strip 400 along the long axis direction of the optical cable are driven to be pressed down and the notch 4011 bulges, meanwhile, the ends of the support sections 402 of the special-shaped buffer strip 400, which are abutted against the ends in the clamping grooves 201, are also driven to move upwards along with the deformation of the buffer sections 401, so that the two opposite support sections 402 of the special-shaped buffer strip 400 on the upper side and the lower side can generate an acting force of the clamping grooves 201, at this time, the core wire 200 can be regarded as an inner layer and an outer layer, the clamping grooves 201 are positioned on the outer layer, the outer layer is opened and deformed, at this time, and the inner layer generates a reverse acting force on the inner layer, at this time, the acting force on the core wire 200 is still mainly takes a circumferential acting force, the inner optical fiber 300 is only pressed down by an extrusion acting force brought by the internal space deformation of the extremely small core wire 200, and the vibration acting force is periodically applied, after the acting force, the tiny deformation of each part is reset extremely fast to cope with the acting force generated next vibration acting force, namely the acting force generated by the vibration deformation due to the multipoint, the small amplitude dispersing deformation and the small amplitude dispersing deformation are generated, when the optical cable is subjected to the vibration deformation is greatly weakened, and the effect is weakened, when the vibration deformation is greatly and the vibration deformation is realized, and the vibration effect is realized is greatly and the long time.
Further, the method comprises the steps of,
the supporting arch body 101 is arranged between the supporting sections 402 of the two adjacent special-shaped buffer strips 400, the supporting arch body 101 is arranged corresponding to the clamping groove 201, the supporting arch body 101 arches towards the axle center to support and separate the two special-shaped buffer strips 400, so that the buffer effect is weakened due to the fact that the special-shaped buffer strips 400 on the upper side and the lower side are mutually extruded when an optical cable is stressed, meanwhile, a cavity is formed among the supporting arch body 101, the supporting sections 402 and the clamping groove 201, a hollow elastic tube 500 is arranged in the cavity, the buffer effect can be further enhanced due to the arrangement of the hollow elastic tube 500, the collision of the special-shaped buffer strips 400 on the upper side and the lower side is effectively blocked, and better separation and isolation effects are generated;
the outer side of the supporting arch body 101 is also provided with a compression-resistant buffer cavity 102;
as shown in fig. 3, the compression-resistant buffer cavity 102 is in a drop shape, the tip end of the compression-resistant buffer cavity 102 is arranged outwards, when the upper side and the lower side of the optical cable are subjected to the action of external force and the special-shaped buffer strip 400 is deformed, two ends of the buffer section 401 are compressed and gathered to form a buffer space, the acting force of the support section 402 on the core wire 200 is reduced, and at the moment, due to the deformation displacement of the support section 402, the cavity is deformed and is suitable for the elliptical deformation of the hollow elastic tube 500, so that the compression-resistant effect of the optical cable is remarkably improved, and meanwhile, when the optical cable is subjected to the action of vibration collision, the two side end parts of the optical cable can more easily generate the buffer effect through displacement vibration, and the compression resistance and the shock resistance of the optical cable are comprehensively improved;
the rounded end inner wall of the compression-resistant buffer cavity 102 is further provided with the arc-shaped elastic tube 1021 in a fitting manner, and the compression-resistant buffer cavity 102 is of a cavity structure, so that the deformation of the sheath layer 100 and the deformation of the supporting arch 101 are facilitated to achieve dispersed guide force and buffer after the compression-resistant buffer cavity is arranged, but the deformation difficulty of the sheath layer 100 is reduced, the bearing compression-resistant threshold of the compression-resistant buffer cavity is slightly reduced, and after the arc-shaped elastic tube 1021 is arranged, the effect of the original compression-resistant buffer cavity 102 is maintained, meanwhile, the actual bearing compression-resistant threshold of the whole flat optical cable is improved, and the front effect is remarkable for improving the use effect of the optical cable.
