Description

Technical Field

[0001] This utility model relates to the field of rivet nut technology, specifically an outdoor multi-core fiber optic connector. Background Technology

[0002] Multi-core fiber is a type of optical fiber that contains multiple cores within the same cladding. This design allows for the expansion of optical fiber capacity without increasing the space and cost of cable laying, thus better overcoming the limitations of single-mode fiber transmission capacity. In the application of multi-core fiber, corresponding multi-core fiber connectors are required.

[0003] Multi-core fiber optic connectors are a technology that contains multiple fiber cores within a single optical fiber. They are mainly used for high-density fiber optic connections. However, some multi-core fiber optic connectors need to be used outdoors. Therefore, when used outdoors, the outer sheath is prone to wear and tear, which can directly affect the service life of the multi-core fiber optic connector. Utility Model Content

[0004] The purpose of this utility model is to provide an outdoor multi-core fiber optic connector to solve the problem mentioned in the background art that some multi-core fiber optic connectors need to be used outdoors, and therefore the outer sheath is prone to wear when used outdoors, which directly affects the service life of the multi-core fiber optic connector.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an outdoor multi-core fiber optic connector, comprising a connector body and an extension connector, wherein an end is fixed to the side of the connector body, a hollow groove is formed in the end, an outer protective sleeve is fitted on the outside of the connector body, a first slot and a second slot for limiting positioning are formed on the outer wall surface of the connector body, a protruding first protrusion is fixed to the inner wall surface of the outer protective sleeve, the first protrusion is positioned in the first slot for limiting positioning, a first positioning post for positioning is inserted in the second slot, and a main connector is fixed to the side of the extension connector.

[0006] As a further technical solution of this utility model, the boss is protruding and the bosses are evenly distributed in a ring around the center of the outer protective sleeve.

[0007] As a further technical solution of this utility model, a second protrusion for locking is arranged between the connector body and the main connector. A fourth slot for matching the protruding position of the second protrusion is provided in the outer protective sleeve. An anti-slip end is fixed on the side of the outer protective sleeve. A recessed arc groove is formed on the anti-slip end. A cylinder is fixed on the arc groove. A boss is fixed on the outside of the outer protective sleeve. A recessed groove is formed on the outer wall of the side of the connector body. The number of cylinders is the same as the number of arc grooves. The cylinders are located inside the annular ring about the center of the outer protective sleeve.

[0008] As a further technical solution of this utility model, both the connector body and the extension joint are provided with receiving grooves, and the external dimensions of the end are smaller than the external dimensions of the connector body.

[0009] As a further technical solution of this utility model, a recessed third slot is provided on the side of the main connector, and a second locking post is installed in the position of the third slot.

[0010] As a further technical solution of this utility model, a sealing ring is fixed in the receiving groove near the extension joint port, and a concave fine ring groove is opened at the connection between the connector body and the end.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this type of outdoor multi-core fiber optic connector not only improves the external protection capability, but also improves the assembly capability and subsequent fixing capability of the multi-core fiber optic connector.

[0012] By attaching an outer protective sleeve to the outside of the connector body, and fixing an anti-slip end to the side of the outer protective sleeve, a recessed arc groove is formed on the anti-slip end, and a cylinder is fixed on the arc groove. Therefore, the combination of the anti-slip end and the cylinder facilitates manual operation during operation. Similarly, the design of the recessed groove also facilitates manual operation. At the same time, after the outer protective sleeve is attached, protrusions are evenly fixed on the outer surface of the outer protective sleeve. Therefore, after the protrusions are extended, they can contact the external environment, such as the ground, thereby replacing the original direct contact with the connector body. Thus, the external protection effect of the connector body is improved when used outdoors, and the service life is increased.

[0013] By assembling a second protrusion between the inner wall of the connector body and the main connector, and opening a third slot so that it can cooperate with the second locking post to form a connection and positioning, a fourth slot is opened in the outer protective sleeve for matching the protruding position of the second protrusion. At the same time, a first slot and a second slot for limiting are opened on the outer wall surface of the connector body, and a protruding first protrusion is fixed on the inner wall surface of the outer protective sleeve. The first protrusion cooperates with the first slot for limiting, and a first locking post for positioning is inserted in the second slot. Thus, it has a good assembly and positioning capability during assembly.

[0014] By fixing the end to the side of the connector body and creating a hollow groove in the end, and by creating a recessed fine ring groove at the connection between the connector body and the end, the hollow groove and the fine ring groove allow for connection and positioning during use by using accessories such as cable ties to clamp the outside of the fine ring groove or pass through the hollow groove. The other end of the cable tie can be fixed to other positions, reducing the problem of the connector body shifting randomly during use. Attached Figure Description

An end 2 is fixed to the side of the connector body 1, and a hollow groove 3 is formed in the end 2. An outer protective sleeve 4 is fitted onto the outside of the connector body 1. A first slot 14 and a second slot 15 for positioning are formed on the outer wall of the connector body 1. A protruding first protrusion 12 is fixed to the inner wall of the outer protective sleeve 4. The first protrusion 12 is positioned in the first slot 14 for positioning, and the second slot 15... A first locking post 13 for positioning is inserted, a main connector 6 is fixed to the side of the extension connector 7, a second protrusion 18 for locking is arranged between the connector body 1 and the main connector 6, a fourth locking groove 19 is opened in the outer protective sleeve 4 for matching the protruding position of the second protrusion 18, an anti-slip end 5 is fixed to the side of the outer protective sleeve 4, a recessed arc groove is formed on the anti-slip end 5, a cylinder 8 is fixed on the arc groove, a boss 9 is fixed to the outside of the outer protective sleeve 4, and a recessed groove 11 is formed on the outer wall of the side of the connector body 1.

[0022] The boss 9 is protruding and is evenly distributed in a ring around the center of the outer protective sleeve 4.

[0023] The number of cylinders 8 is the same as the number of arc grooves, and the cylinders 8 are located inside the annular ring around the center of the outer protective sleeve 4.

[0024] Both the connector body 1 and the extension joint 7 are provided with receiving grooves 10, and the external dimensions of the end 2 are smaller than the external dimensions of the connector body 1.

[0025] The main connector 6 has a recessed third slot 17 on its side, and a second locking post 16 is installed in the third slot 17.
