Description

Tensile structure of outdoor optical cable

Technical Field

The utility model relates to an optical cable technical field especially relates to an outdoor optical cable tensile structure.

Background

The special optical fiber connector generally comprises a main body shell, a dust cap, a tail accessory and a plug core contact piece. When the tail part is connected with an outdoor optical cable, the diameter of the outdoor optical cable is larger, the surface of the outdoor optical cable is harder, the pressing ring is generally adopted to extrude the silica gel pad to deform, and the optical cable is fixed by the deformed silica gel pad and the glue filling ring. The structure has the problems that the glue filling ring, the silica gel pad and the press ring are required to be fixed on the optical cable at present, the production process is complicated, a positioning structure is not arranged between the glue filling ring and the extension rod, if the glue filling ring rotates in the extension rod, the optical fiber is broken due to rotation, the situation is fatal, in addition, the outdoor optical cable structure is different from the conventional remote optical cable and armored optical cable, the optical cable has high sheath hardness, is wear-resistant and tensile, and the optical cable has no tensile element which is common to the conventional optical cable in the internal structure; therefore, it is necessary to design a tail accessory structure which is suitable for the outdoor optical cable and can effectively prevent the falling, rotation and tension.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that has outdoor light to rotate among the prior art and can lead to the optic fibre rupture, and the outdoor optical cable tensile structure who provides.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

designing an outdoor optical cable tensile structure, which comprises an integrated extension bar, wherein the integrated extension bar comprises a bar body, one end of the bar body is a crimping part, an anti-skidding thread is fixedly arranged on the inner side of the crimping part, an external thread is fixedly arranged in the middle of the bar body, a plurality of penetrating positioning screw holes are formed in the outer side of the external thread, and the positioning screw holes are uniformly distributed around the integrated extension bar; the tip cover of integral type extension bar is equipped with the tail-hood, the tail-hood includes the lid, the one end of lid is the rotating part, the inboard fixed mounting of the lid other end have with external screw thread assorted internal thread, the tail-hood can with integral type extension bar threaded connection.

Preferably, the inner side of the positioning screw hole is provided with a headless screw in a threaded manner, and the inner end of the headless screw can be in contact with the optical cable.

The utility model provides a pair of outdoor optical cable tensile structure, beneficial effect lies in: when the optical cable is placed, the crimping machine is used for crimping the crimping part at the front end of the integrated extension bar to fix the optical cable, then the fixed optical cable is locked by a headless screw to be fixed to prevent rotation, and double fixing effects are achieved; then the tail cover is matched with the integrated lengthening rod through threads; the design not only improves the production efficiency, but also avoids the condition that the optical fiber of the optical cable is broken in the tail attachment.
