Optical fiber fusion splicing protection device

Technical Field

The utility model relates to an optical fiber fusion splicing protection device, and belongs to the technical field of optical fibers.

Background

Along with the continuous construction of various national large-scale civil engineering and the continuous importance on the building safety, the sensor use quantity on the public building is continuously increased, and the welding requirement of various sensors adopting the optical fiber sensing technology in the construction process is continuously increased. Because the optical fiber splice point is comparatively fragile, is damaged in the work progress easily, simultaneously, because the diameter of all kinds of tail optical fibers, wire jumper differs, for guaranteeing the protection to the butt fusion position, guarantee simultaneously that not unidimensional tail cable or wire jumper can dock smoothly, consequently in traditional mode, adopt the optic fibre splice box to protect it more. However, this method has the following problems:

1. the optical fiber splice closure is troublesome in the installation process, and more labor and time are consumed;

2. the optical fiber splice closure is large in size and cannot be used in a small space;

3. fiber optic closures are expensive and add cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing an optical fiber fusion splicing protection device aiming at the prior art, which is convenient to install, small in size, free of influence on normal wiring of a sensor tail cable and strong in field adaptability.

The technical scheme adopted by the utility model for solving the problems is as follows: the optical fiber fusion welding protection device comprises a hollow connecting pipe, wherein fused optical fibers penetrate through the connecting pipe; the connecting pipe both ends set up the retaining member respectively, the retaining member that corresponds the side is worn to establish at the optic fibre both ends, makes the splice point of optic fibre is located in the connecting pipe, the optic fibre tip exposes the retaining member that corresponds the side.

The connecting pipe is an ABS hard plastic pipe.

The retaining member is a variable-diameter waterproof joint, and the variable-diameter waterproof joint is in threaded connection with the connecting pipe. Compared with the prior art, the utility model has the advantages that: the utility model provides an optical fiber fusion splices protection device, wears to establish the connecting pipe with the optic fibre after the butt fusion, and the optic fibre both ends are drawn forth by the water joint at connecting pipe both ends respectively for the splice point is located in the connecting pipe. The sensor tail cable is convenient to install, small in size, free of influence on normal wiring of the sensor tail cable, capable of guaranteeing protection requirements on welding points, low in price and high in field adaptability.
