[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0025] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0027] Reference Figure 1-6A polarization-maintaining optical fiber assembly for a high-density communication system includes an optical fiber 1. Optical fiber connectors 2 are provided at both ends of the optical fiber 1. The connection of the optical fiber 1 is achieved through the optical fiber connector 2. A first fixing ring 5 is provided on the surface of the optical fiber connector 2. A first joint 3 and a second joint 4 are connected to the optical fiber 1 through the setting of the first fixing ring 5. A first connecting assembly 6 is provided on the surface of the first fixing ring 5. The first connecting assembly 6 consists of a first connecting block 601, a first rotating block 602, a second rotating block 603 and a first rotating shaft 604. The side of the first connecting block 601 is provided with a first rotating block 602, the side of the first rotating block 602 is provided with a second rotating block 603, the surface of the first rotating block 602 is provided with a first rotating shaft 604, the shape of the first connecting block 601 corresponds to the side of the second joint 4, and the first rotating block 60 2 and the second rotating block 603 are axially connected by the first rotating shaft 604. When the first joint 3 and the second joint 4 rotate horizontally, the first rotating block 602 and the second rotating block 603 rotate through the first rotating shaft 604, thereby adjusting the bending angle of the optical fiber 1. The surface of the first connecting component 6 is provided with a first joint 3, and the shape of the first joint 3 is a truncated cone. Due to the shape characteristics of the truncated cone, there is a movable space between the first joint 3 and the second joint 4, and the rotation is limited by the angle to avoid excessive bending of the optical fiber 1. The first joint 3 and the second joint 4 have the same shape, and the first joint 3 and the second joint 4 are staggered. The small-diameter direction of the first joint 3 and the large-diameter direction of the second joint 4 are connected through a component, and the optical fiber 1 is protected to prevent friction of the optical fiber 1.

[0028] A second connecting assembly 7 is provided at the end of the first joint 3, and the second connecting assembly 7 consists of a second connecting block 701, a third rotating block 702, a fourth rotating block 703 and a second rotating shaft 704. The side of the second connecting block 701 is provided with a third rotating block 702, the side of the third rotating block 702 is provided with a fourth rotating block 703, and the surface of the third rotating block 702 is provided with a second rotating shaft 704. The shape of the second connecting block 701 corresponds to the side of the first joint 3, and the third rotating block 702 and the fourth rotating block 703 are axially connected by the second rotating shaft 704. When a vertical rotation occurs between the first joint 3 and the second joint 4, the third rotating block 702 and the fourth rotating block 703 are connected by the second rotating shaft 70 4 is rotated to adjust the bending angle of the optical fiber 1. A second joint 4 is provided on the surface of the second connecting component 7. The first connecting component 6 and the second connecting component 7 are alternately arranged between the first joint 3 and the second joint 4. The structure of the first connecting component 6 is the same as that of the second connecting component 7. The direction of the first connecting component 6 is vertically arranged, and the direction of the second connecting component 7 is horizontally arranged. Through the arrangement of the first connecting component 6 and the second connecting component 7, it is convenient for the optical fiber 1 to be bent at multiple angles. A second fixing ring 8 is provided on the surface of the optical fiber connector 2. The surface of the second fixing ring 8 is connected to the side of the second connecting component 7. The first joint 3 and the second joint 4 are connected to the optical fiber 1 through the second fixing ring 8.

[0029] When the optical fiber 1 is bent horizontally, a horizontal rotation occurs between the first joint 3 and the second joint 4, so that the first rotating block 602 and the second rotating block 603 rotate through the first rotating axis 604, thereby adjusting the horizontal bending angle of the optical fiber 1. When the optical fiber 1 is bent vertically, a vertical rotation occurs between the first joint 3 and the second joint 4, so that the third rotating block 702 and the fourth rotating block 703 rotate through the second rotating axis 704, thereby adjusting the vertical bending angle of the optical fiber 1. Due to the shape characteristics of the first joint 3 and the second joint 4, there is room for movement between the first joint 3 and the second joint 4, but the bending angle of the optical fiber 1 is limited, effectively avoiding excessive bending of the optical fiber 1 and causing breakage of the optical fiber 1, facilitating the protection of the optical fiber 1 and ensuring the use of the optical fiber 1. Specific embodiment 2:

[0031] Reference Figure 7 , which is a state diagram of the optical fiber 1 when it is bent. The first joint 3 and the second joint 4 are rotated by the mutual cooperation between the first connecting components 6, so that the optical fiber 1 is bent to a certain angle, avoiding excessive bending of the optical fiber 1 and facilitating the use of the optical fiber 1.

[0032] In summary:

[0033] 1. The first joint 3, the second joint 4, the first connecting component 6 and the second connecting component 7 are adopted, and the first connecting component 6 and the second connecting component 7 are alternately arranged between the first joint 3 and the second joint 4. When the optical fiber 1 is bent, the first connecting component 6 or the second connecting component 7 will rotate, so that the first joint 3 and the second joint 4 rotate through each component to make the optical fiber 1 bend. However, due to the cooperation of the first joint 3 and the second joint 4, the bending angle of the optical fiber 1 is limited, which effectively avoids excessive bending of the optical fiber 1 and causes the optical fiber 1 to break, which is convenient for protecting the optical fiber 1 and ensures the use of the optical fiber 1 in a high-density communication system.
