Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connection, in particular to a multi-core optical fiber connection mechanism. Background Art

[0002] Multi-core optical fiber has multiple cores in a common cladding area. Due to the close proximity of the cores, it can have two functions. One is that the core spacing is large, that is, the structure does not produce light coupling. This type of optical fiber can increase the integration density per unit area of ​​the transmission line. In optical communications, ribbon cables with multiple cores can be made, and in non-communication fields, as optical fiber image transmission bundles, there are tens of thousands of cores. The second is to make the distance between the cores close, which can produce light wave coupling. Dual-core sensors or optical circuit devices are being developed using this principle. When connecting multi-core optical fibers, a connecting mechanism is required for connection;

[0003] The existing patent with the authorization announcement number "CN209728237U" discloses a multi-core optical fiber connector, which fixes the relative position of the central reinforcing core on the left and right sides, thereby fixing the relative position of the optical fibers on the left and right sides. It is easy to install, easy to operate and small in size, and enhances the stability and tensile strength of the optical fiber connection to increase the working stability of the optical fiber. The optical fiber connection is protected, and the operation is simple and convenient, easy to operate, high in stability, not easy to damage, and increases the dustproofness, waterproofness and pressure resistance of the optical fiber connector, and increases the working stability of the optical fiber.

[0004] However, there are the following deficiencies in this device:

[0005] The protection effect of the connection is poor, so dust may enter the connector from the connection and damage the optical fiber, affecting the transmission speed of the optical fiber. In addition, when used for a long time, the connector may loosen and fall off, reducing the connection stability of the device. Utility Model Content
