Further, the oversheath sidewall adhering and solidifying of described polyurethane adhesive and optical cable part is integral.
Further, between the oversheath sidewall of the optical cable in described device cabin part and coated polyurethane adhesive, form an angle of taper.
Further, in the one end, device cabin that is provided with positioning spiro pit, by end cap, compress polyurethane adhesive, described end cap is provided with tapped hole, this tapped hole is corresponding with the positioning threads hole site in device cabin, and passes the tapped hole of end cap and the positioning spiro pit in device cabin is fixed on end cap on device cabin by screw.
Further, the positioning spiro pit of one end, described device cabin is two.
Further, the optical cable that stretch out one end, described device cabin is partly two.
Further, described device cabin is cylindrical structural.
The beneficial effects of the utility model, the polyurethane adhesive adopting due to the utility model is coated sealing configuration entirely, after polyurethane adhesive and optical cable part oversheath adhering and solidifying, form high-strength adhesive power, reduce the interfacial area of polyurethane adhesive and metal, make water molecule under high hydraulic pressure along the oversheath of optical cable part, not be penetrated into the inside configuration in device cabin, realize the sealing in optical cable and device cabin.Effectively solved the sealing problem that is operated in high hydraulic pressure field device, and had novel structure, designed ingeniously, reliability is high, processing and use all advantage easily.
And device cabin is metallic material, after metallic material and glue bonding, be immersed in for a long time the water the inside of high hydraulic pressure, can cause unavoidably the inefficacy of glue and metal cohesive force, by pressing plate, the glue of its end face is fixed, form axial pressure, guarantee polyurethane adhesive and seamless contact of device cabin end face, make water molecule along the separating surface infiltration of device cabin end face and glue, further not realize the sealing of fibre optic hydrophone.
