Problems solved by technology
[0003] The purpose of the present invention is to provide a plugging member for an optical cable splice box, aiming at the inconvenient operation, poor sealing performance and the inability of a single plugging post to seal the inlet and outlet of the optical cable splice box in the prior art. To adapt to the problems of different diameters of optical cables and poor operability, the design of sealing parts is used to seal the inlet and outlet of optical cable splice boxes

Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] like figure 1 As shown, the sealing column 2 is composed of three coaxial rubber tubes, and the adjacent rubber tubes are bonded together; except for the outermost rubber tube, the side walls of the other rubber tubes are provided with openings 2-1 along the length direction;
[0025] In this embodiment, the rubber tube is a circular tube, the inner diameter of the innermost rubber tube is 8mm, and the inner diameter of the outermost rubber tube is 12mm;
[0026] like figure 2 As shown, the protective case 1 is composed of two parts, the dividing line is along the axial direction (see Figure 4(b)), the end surface of the protective case 1 has overlapping areas at both ends of the joint, and corresponding protrusions 1-2 are provided in the overlapping areas. , Groove 1-3 for fastening;
[0027] As shown in Figure 3(a) and F...

The invention discloses an optical cable splice closure occluder which comprises a protection shell and a sealing pillar inside the protection shell. Both an inner diameter of the sealing pillar and an end face opening of the protection shell can be subjected to corresponding size regulation according to different sizes of optical cables, so that one single occluder can be applicable to differentdiameters of optical cables and is good in operability; and sealing performance among the sealing pillar, the protection shell and the optical cable and between the protection shell and the sealing pillar is good, the optical cable splice closure occluder takes a protection effect on the optical cable, sealing performance of an inlet and outlet port of an optical cable splice closure can also be improved, and a moisture-proof effect is good.
Description
technical field [0001] The invention relates to a sealing piece for an optical cable joint box. Background technique [0002] After the optical fiber joint is protected by the optical cable splice box, it should be able to avoid the erosion of moisture, and the attenuation of the optical fiber joint before protection should not be increased. Therefore, the sealing performance of the optical cable splice box is very high. However, when the optical cable splice box is used, it adopts methods such as underground direct burial, pipe suspension, and overhead suspension, which cause the optical cable splice box, especially the cable inlet and outlet of the optical cable splice box, to be easily eroded by moisture. In the prior art, a sealing ring or a plugging column is generally used to seal the inlet and outlet of the optical cable splice box. When using the sealing ring, first select the sealing ring with the smallest inner diameter according to the outer diameter of the optic...
