Description

Technical Field

[0001] The utility model relates to the technical field of optical communication, in particular to a sealing mechanism for an OPGW optical unit. Background Art

[0002] For the existing OPGW optical unit access connection device, generally, sealant is directly used to seal the interface, and then the nut for tightening the OPGW optical unit is tightened to play a sealing role.

[0003] The sealing performance of the existing connection device cannot be fully guaranteed in environments with high salt spray, high chemical pollution, and a large number of ants. The sealant will gradually weather under conditions such as high salt spray, high chemical pollution, high and low temperatures. Ants will bite the sealant and gradually bite open a channel in the sealant, invading and biting the optical fiber unit inside the connection device. Water vapor and harmful substances in the air will also enter the connection device, causing internal structure pollution and corrosion, resulting in embrittlement of the optical fiber, thus seriously affecting line communication. Summary of the Utility Model

[0004] The technical problem to be solved by the embodiment of the utility model is to provide a sealing mechanism for an OPGW optical unit to solve the technical problems that the sealant will gradually weather under conditions such as high salt spray, high chemical pollution, high and low temperatures and cannot prevent ants.

[0005] To solve the above technical problem, the embodiment of the utility model provides a sealing mechanism for an OPGW optical unit, including a body. A wire passing hole is arranged in the body. The body is composed of a wire passing pipe, a sealing piece, and a sealing plug. The wire passing pipe is arranged on the sealing piece, and the sealing plug is arranged below the sealing piece. The diameter of the sealing plug is smaller than that of the sealing piece. The wire passing hole penetrates through the sealing plug, the sealing piece, and the wire passing pipe.

[0006] Further, the upper part of the sealing plug is wide and the lower part is narrow.

[0007] Further, there are multiple groups of wire passing holes and wire passing pipes.

[0008] The beneficial effect of the utility model is that the utility model can tightly wrap the OPGW optical unit passing through the wire passing hole, and at the same time can be firmly sealed with the cable inlet pipe, realizing the sealing of the connection device, and can solve the technical problems that the sealant will gradually weather under conditions such as high salt spray, high chemical pollution, high and low temperatures and cannot prevent ants.

[0022] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0023] In the embodiments of the present utility model, if there are directional indications (such as up, down, left, right, front, back...), they are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0024] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0025] Please refer to Figures 1 to 10 , the OPGW optical unit sealing mechanism of the embodiment of the present utility model includes a body. The body is a rubber body.

[0026] A wire passing hole is provided in the body. The body is composed of a wire passing tube, a sealing piece, and a sealing plug, and the wire passing tube, the sealing piece, and the sealing plug are integrally formed. The wire passing tube, the sealing piece, and the sealing plug are arranged in sequence from top to bottom. The wire passing tube is provided on the sealing piece, and the sealing plug is provided below the sealing piece. The diameter of the sealing plug is smaller than the diameter of the sealing piece, and the wire passing hole penetrates through the sealing plug, the sealing piece, and the wire passing tube. The sealing piece is preferably circular.

[0027] As an implementation manner, the sealing plug is wider at the top and narrower at the bottom, which is convenient for users to install the OPGW optical unit sealing mechanism on the cable inlet tube of the splicing device and can also make the OPGW optical unit sealing mechanism and the cable inlet tube more tightly sealed.

[0028] As an implementation manner, the wire passing hole is a conical hole that is narrower at the top and wider at the bottom. The conical hole is convenient for the OPGW optical unit to pass through and can tightly wrap the OPGW optical unit at the same time. Specifically in implementation, the top of the wire passing hole can be sealed. When in use, according to the specifications of the OPGW optical unit, the top of the wire passing tube can be cut off.

[0029] As an implementation manner, the wire passing tube is conical, which can save materials and costs. The wire passing tube is preferably conical.

[0030] As an implementation manner, there are multiple groups of wire passing holes and wire passing tubes, which can be applied to the practical use of splicing devices with different specifications.

[0031] Embodiment 1: There is 1 group of wire passing holes and wire passing tubes, as shown in Figures 1 to 4 . Embodiment 2: There are 2 groups of wire passing holes and wire passing tubes, as shown in Figures 5 to 7 . Embodiment 3: There are 3 groups of wire passing holes and wire passing tubes, as shown in Figures 8 to 10 .

[0032] Please refer to Figure 11 , the splicing device of the embodiment of the present utility model includes a base and a splicing mechanism provided on the base. A cable inlet tube for facilitating the OPGW optical unit to pass through is provided on the base. The cable inlet tube facilitates the OPGW optical unit to access the inside of the splicing device from the outside. An OPGW optical unit sealing mechanism for sealing between the OPGW optical unit and the cable inlet tube is provided in the cable inlet tube.

[0033] As an implementation manner, the connection device further includes a nut. The outer periphery of the inner end of the cable inlet pipe is provided with a thread. The nut has a hole in the middle and is arranged on the cable inlet pipe through the thread to seal the OPGW optical unit sealing mechanism in the cable inlet pipe. The nut improves the sealing performance of the connection device.
