Embodiment
[0028] like figure 1 , figure 2 In the shown embodiment, a waterproof optical cable splicing device that can absorb redundant release includes a base 1, a cover 2 that opens and closes the base, a flange 3 that matches the base, and a double-layer silicone pad 4, 5 studs, 6 anti-theft nuts. Among them, the diameter of the base is 24cm, the height is 8.5cm, and the thickness is 0.5cm; the diameter of the cover is 26.5cm, the height is 2cm, and the thickness is 0.5cm; the diameter of the flange is 17cm, and the height is 4cm; Figure 5 , Image 6 As shown, the inner diameter of the double-layer silicone pad is 22.5cm, the outer diameter is 24.5cm, and its section is H-shaped; the diameter of the stud is 1.5cm, the length is 11.5cm, and the anti-theft nut: the diameter is 4cm, and the height is 3.6cm.
[0029] The shape of the base is drum-shaped. The drum-shaped appearance can avoid rainwater retention and effectively reduce the possibility of water vapor infiltration. Corre...

Abstract
The invention discloses a waterproof optical cable connection device capable of absorbing and releasing redundancy. The device comprises a base, a cover body for opening and covering the base, a welding disc matched with the base, and a double-layer silica gel pad. The base is provided with an optical fiber inlet and outlet and an installation space allowing the optical fiber to stretch to the maximum extent, the optical fiber inlet and outlet is communicated with the installation space, the cover body and the base are connected in a sealing mode through the double-layer silica gel pad, a sealing piece is arranged at the optical fiber inlet and outlet, the welding disc is arranged in the base, and the optical fiber is wound on the welding disc. According to the scheme, the double-layer silica gel pad is used for replacing a rubber sealing ring, the service life of the sealing ring is prolonged, and the service life of the double-layer silica gel pad under the outdoor natural condition is 30 years or more. A double-layer structure is adopted, so that a better anti-seepage effect is achieved. And meanwhile, the shape of the installation space is changed to improve the extensibility of the optical fiber in the device, and the sub-fiber core included angle is prevented from being too small.
Description
technical field [0001] The invention relates to the field of communication optical cable connection accessories, in particular to a waterproof optical cable connection device capable of absorbing redundancy and releasing. Background technique [0002] The optical cable splicing device is a connection part that connects two or more optical cables together and has protective components. It must be used in the construction of optical cable lines, and it is one of the very important equipment. Its quality directly affects the quality of optical cable lines. and the service life of the cable line. [0003] In the prior art, power special optical cables are generally erected in high mountains and hilly areas, and the device is shrouded in fog all year round. Under the action of the pressure difference inside and outside the device, water vapor will continuously penetrate into the device. Cause water accumulation in the device and continuously corrode the steel core and bare optic...
