Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber connectors, in particular to an environment-resistant optical fiber connector. Background Art

[0002] A fiber optic connector is a device that makes a detachable (movable) connection between optical fibers. It precisely connects the two end faces of the optical fiber so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent possible, and the impact on the system caused by its involvement in the optical link is minimized.

[0003] In the related art, reference may be made to the Chinese patent with the authorization announcement number CN214067443U, which specifically discloses an environment-resistant optical fiber connector. The utility model has the advantages of stable optical fiber connection and good waterproof and dustproof effects, and is mainly used for optical fiber connection.

[0004] The applicant found that the above-mentioned optical fiber connector mainly adopts the dual cooperation of the inner cover and the upper cover body to achieve the waterproof sealing effect. Although the above method can achieve the sealing effect, the overall heat dissipation effect is poor due to the double-layer shell; secondly, during use, the optical fiber is often dragged. When dragging, the optical fiber is easy to fall out of the optical fiber connector or the connection is not tight enough. All of the above will affect the effect of data transmission and fail to meet the growing usage needs.

[0005] In view of this, an environment-resistant optical fiber connector is proposed. Utility Model Content

[0008] A bottom shell body, which has a receiving cavity, a fiber optic adapter is arranged at the center of the receiving cavity, and a sealing assembly is arranged on the bottom shell body;

[0009] The sealing assembly comprises an upper cover, a lower sealing ring and an upper sealing ring, and the contact end surfaces of the upper cover and the bottom shell are respectively recessed inward to form a square groove that meets the requirements of embedding the lower sealing ring and the upper sealing ring;

[0010] Slots are provided on the bottom wall of the bottom shell at both sides of the optical fiber adapter, positioning plates are provided on both sides of the bottom wall of the upper cover corresponding to the slots, and a through hole is provided in the middle of the positioning plate to allow the optical fiber to pass through.

[0011] In a preferred embodiment, when the bottom shell and the upper cover are installed together, the lower sealing ring and the upper sealing ring are interference fit together to achieve a waterproof sealing operation.

[0012] In a preferred embodiment, both ends of the opposite sides of the bottom shell and the upper cover are recessed inward to form semicircular threading grooves for the insertion of optical fibers.

[0013] In a preferred embodiment, a plurality of threaded holes are circumferentially formed on the upper end surface of the bottom shell, a plurality of light holes are formed on the upper cover corresponding to the threaded holes, and the bottom shell and the upper cover are fixed together by a plurality of screws.

[0014] In a preferred embodiment, the size of the through hole is smaller than the size of the optical fiber connection end, and after the optical fiber connection end is inserted into the optical fiber adapter, the positioning plate abuts against the outer end surface of the optical fiber connection end.

[0015] In a preferred embodiment, the upper cover is made entirely of aluminum alloy material, and a plurality of heat dissipation fins are provided on the upper end surface of the upper cover.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. In the utility model, upper and lower sealing rings are designed at the connection between the upper cover and the bottom shell. The interference fit between the bottom shell, the upper cover and the sealing ring can achieve waterproof and dustproof effects on the internal optical fiber connection part, thereby improving the stability of signal transmission;

[0024] Reference Figure 1-3 , an environment-resistant optical fiber connector, comprising: a bottom shell 1, which has an accommodating cavity 101, a fiber optic adapter 102 is arranged at the center of the accommodating cavity 101, and a sealing assembly is arranged on the bottom shell 1; the sealing assembly comprises an upper cover 4, a lower sealing ring 2 and an upper sealing ring 3, and the contact end surfaces of the upper cover 4 and the bottom shell 1 are respectively recessed inward to form a square groove 105 that meets the requirements of embedding the lower sealing ring 2 and the upper sealing ring 3. When the bottom shell 1 and the upper cover 4 are installed together, the lower sealing ring 2 and the upper sealing ring 3 are interference fit together to achieve a waterproof sealing operation, and the upper sealing ring 3 and the lower sealing ring 2 are respectively designed at the connection between the upper cover 4 and the bottom shell 1. The interference fit between the bottom shell 1, the upper cover 4 and the sealing ring can achieve a waterproof and dustproof effect on the internal optical fiber connection part, and can be used in dusty and humid environments.

[0025] Wherein, the lower sealing ring 2 and the upper sealing ring 3 are both made of silicone or rubber sealing rings.

A through hole 4031 is provided in the middle of the positioning plate 403 to allow the optical fiber to pass through. The size of the through hole 4031 is smaller than the size of the optical fiber connection end, and after the optical fiber connection end is inserted into the fiber optic adapter 102, the positioning plate 403 abuts against the outer end surface of the optical fiber connection end. A positioning plate 403 is designed at the bottom of the upper cover 4. After the optical fiber is inserted into the fiber optic adapter 102, when the upper cover 4 is fixed on the bottom shell body 1, one end of the positioning plate 403 abuts against the outer end surface of the optical fiber connection end (not shown in the figure) of the optical fiber, which is used to position the optical fiber, thereby preventing the optical fiber from falling off during dragging, thereby ensuring the effect of optical fiber transmission.

[0027] In this embodiment, both ends of the opposite sides of the bottom shell 1 and the upper cover 4 are recessed inward to form a semicircular threading groove 106 for the insertion of the optical fiber. After the optical fiber is connected to the optical fiber adapter 102, when the upper cover 4 is fixed on the bottom shell 1, the upper cover 4 and the bottom shell 1 will not squeeze the optical fiber, thereby ensuring the transmission effect of the optical fiber signal.
