Description

Technical Field

[0001] This utility model relates to the field of fiber optic connector technology, specifically to a protective sleeve for an MPO connector that is easy to install and remove. Background Technology

[0002] In large computer rooms or data centers, fiber optic cables are commonly used for data transmission. Because fiber optic cables are densely packed in computer rooms or data centers with very little space, it is difficult for engineers to directly access the connectors to plug and unplug the fibers, and there is no extra space for cable pullers, making maintenance extremely inconvenient. Therefore, it is necessary to design a kit to facilitate plugging and unplugging for engineers.

[0003] In existing technologies, the fiber optic connectors used in computer rooms or data centers typically have a cylindrical tube end at the connection point between the fiber optic cable and the male connector. The end of this tube contacts the outer surface insulation layer of the fiber optic cable. When inserting or removing the male connector, the tube end needs to be pinched, which can easily cause deformation of the fiber optic cable insulation layer, potentially damaging it and shortening the lifespan of the connection between the fiber optic cable and the connector. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a convenient MPO connector protective sleeve. It adopts a flared tail tube, which is easy to install, can protect the connection of optical fiber, facilitates the insertion and removal of MPO connectors, facilitates the maintenance work of engineers, enables fast and accurate insertion and removal in dense spaces, extends the service life of MPO connectors, and has relatively high practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a tail tube 1, an upper protective cover 2, a base 3, a limiting protrusion 4, a threading cavity 5, a tail tube flared mouth 6, an anti-slip groove 7, and a limiting groove 8; the upper protective cover 2 and the base 3 are vertically aligned, the left end of the tail tube 1 is connected to the upper protective cover 2 and the base 3, and the tail tube 1 is held inside the upper protective cover 2 and the base 3 by the limiting protrusion 4; the inside of the tail tube 1 is a hollow threading cavity 5, and multiple anti-slip grooves 7 are provided on the surface of the tail tube 1 outside the threading cavity 5, and the limiting groove 8 is located in the middle of the upper part of the upper protective cover 2.

[0006] Furthermore, the upper protective cover 2 has upper protective cover mounting ports 201 on its left and right sides, and the base 3 has base mounting ports 301 on its left and right sides corresponding to the upper protective cover mounting ports 201. After the upper protective cover 2 and the base 3 are installed, the MPO connector is placed in the internal cavity, and the upper protective cover mounting port 201 and the base mounting port 301 on the right side form a circular mounting port. The limiting protrusion 4 is located on the right side of the internal cavity, and the circular mounting port locks the left end of the tail tube 1. The diameter of the limiting protrusion 4 is larger than the diameter of the circular mounting port, thereby restricting the installation position of the tail tube 1.

[0007] Furthermore, the lower part of the upper protective cover 2 is provided with an upper protective cover slot 202, and the left and right sides of the upper protective cover slot 202 are provided with upper protective cover buckles 203 that protrude from the outside to the inside.

[0008] Furthermore, the upper part of the base 3 is provided with an upper protective cover buckle 203, and the upper protective cover buckle 203 is provided with base grooves 302 that are recessed from the outside to the inside on both sides.

[0009] Furthermore, the upper protective cover slot 202 is connected to the base buckle 303 in a size-fitting buckle connection, and the upper protective cover buckle 203 is connected to the base slot 302 in a size-fitting buckle connection.

[0010] Furthermore, the anti-slip groove 7 is a plurality of evenly distributed hollow grooves.

[0011] The working principle of this utility model is as follows: A snap-fit ​​connection is used, and the tail end of the traditional tail tube is designed in a flared shape. A limiting groove matching the size of the upper protrusion of the MPO connector is opened on the upper protective cover to lock the MPO housing. The groove design at the front end of the tail tube also locks the tail tube. When the tail tube is pushed or pulled back and forth, it drives the components to move, thereby moving the MPO housing, allowing the MPO connector to be inserted or removed from the flange without contact.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: it adopts a flared tail tube, which is easy to install, can connect and protect the optical fiber, and facilitates the insertion and removal of the MPO connector, which is convenient for engineers' maintenance work. It can achieve fast and accurate insertion and removal in dense spaces, further protect the optical fiber insulation layer, extend the service life of the MPO connector, and has relatively high practicality.
