Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber conversion connection, in particular to an optical fiber FC converter. Background Art

[0002] Fiber FC converters transmit serial data over optical fiber, converting isolated bus interfaces to optical fiber and extending signal transmission distances. Typically, an FC converter connects armored fiber optic cables at both ends. In some scenarios, such as connecting fiber optic sensors to armored fiber optic cables, the FC converter connects the armored cable at one end and a bare fiber with a protective sleeve at the other.

[0003] In the Chinese patent literature, the publication number is CN218886232U, and the publication date is April 18, 2023. It is named a sleeve-type optical fiber converter, which includes a sleeve and an optical fiber converter body. The optical fiber converter body is located in the sleeve. Cover plates are installed at both ends of the sleeve. A socket is provided in the cover plate. A baffle is slidably fitted in the socket. Brush bristles are installed on the lower side of the baffle. A slot is provided in the cover plate. Plug blocks corresponding to the slots are installed on both sides of the sleeve, and the plug blocks correspond to the baffle. Two clamps are installed in the sleeve. Two buttons are slidably fitted on the side of the sleeve, respectively, and fixed to one side of the two clamps. In the utility model, a sleeve is added to the outer shell of the optical fiber converter body to prevent the optical fiber converter body from being directly exposed to the air, reduce dust from contaminating the optical fiber converter body, and thus reduce the damage caused by dust to the optical fiber converter body.

[0004] In the above-mentioned prior art, a sleeve is added to the outer shell of the optical fiber converter body to prevent the optical fiber converter body from being directly exposed to the air. However, when connecting the optical fiber, the bare optical fiber with the protective tube sleeve is exposed to the air. During use, it is very easy to step on the optical fiber and cause damage to the optical fiber. Utility Model Content

[0005] To address the deficiencies of the above-mentioned prior art, the present invention provides an optical fiber FC converter, which enables the optical fiber protected by a PEEK sleeve to be transferred to an FC ferrule connector formed by an FC ferrule fixing sleeve, an FC connector fastening ring, an FC ferrule, an FC ferrule adapter I, and an FC ferrule adapter II. This ensures that the optical fiber is not exposed outside the protective layer, and that the FC ferrule connector and the protective sleeve form a two-way mechanical connection that can withstand a certain axial tension. The PEEK sleeve and the optical fiber are effectively protected from being stepped on. At the same time, the observation window allows the optical fiber inside the FC ferrule connector to be observed to see if it is broken or compressed, thereby ensuring the reliability of the optical fiber sensor connection.

[0006] The utility model is achieved through the following technical solutions:

[0007] An optical fiber FC converter, characterized by comprising an FC ferrule fixing sleeve, an FC connector fastening ring, an FC ferrule, an FC ferrule adapter I, an FC ferrule adapter II, a PEEK double-pass sleeve, a high-strength outer sheath, a PEEK sleeve, and an optical fiber. The FC connector fastening ring is disposed on the outer surface of the FC ferrule fixing sleeve, and the FC ferrule is assembled therein. One end of the FC ferrule adapter I is threadedly connected to the FC ferrule fixing sleeve, and the other end of the FC ferrule adapter I is threadedly connected to one end of the FC ferrule adapter II. The FC ferrule adapter I is provided with an observation window, and the other end of the FC ferrule adapter II is threadedly connected to the PEEK double-pass sleeve. One end of the PEEK sleeve passes through the PEEK double-pass sleeve and extends into the FC ferrule adapter II, and the other end is provided with a high-strength outer sheath. The optical fiber is disposed in the PEEK sleeve, and one end of the optical fiber extends into the FC ferrule.

[0008] Furthermore, the FC ferrule adapter I includes an adapter sleeve, one end of which is provided with a connecting thread for connecting to an FC ferrule fixing sleeve, the FC ferrule fixing sleeve being provided with a threaded opening adapted to the connecting thread, the other end of the adapter sleeve being provided with a compression connection screw, and one end of the FC ferrule adapter II being provided with a compression connection stud that mates with the compression connection screw, and a through-hole formed in the surface of the adapter sleeve forming an observation window. The adapter sleeve is provided with a connecting thread at one end, a threaded opening adapted to the connecting thread is provided in the FC ferrule fixing sleeve for threaded connection, and a compression connection screw is provided at the other end of the adapter sleeve for connecting to the FC ferrule adapter II. The through-hole formed in the surface of the adapter sleeve forms an observation window, which allows observation of whether the PEEK sleeve is pressing against the optical fiber during compression, thereby adjusting the tension of the optical fiber.

[0009] Furthermore, the FC ferrule adapter II is provided with a PEEK two-way sleeve connecting stud at the other end. The PEEK two-way sleeve has a threaded opening inside the PEEK two-way sleeve that rotatably connects to the PEEK two-way sleeve connecting stud. A wrench opening is provided in the middle of the FC ferrule adapter II. The PEEK two-way sleeve connecting stud at the other end of the FC ferrule adapter II is rotatably connected to the threaded opening inside the PEEK two-way sleeve, thereby mechanically connecting the FC ferrule adapter II to the PEEK two-way sleeve.

[0010] Furthermore, the adapter sleeve is provided with a PEEK sleeve compression opening, and one end of the compression connection stud is provided with a PEEK sleeve compression clamp that cooperates with the PEEK sleeve compression opening. By cooperating with the PEEK sleeve compression opening, the PEEK sleeve is clamped, and the compression connection stud is rotated to connect with the compression connection thread, compressing the PEEK sleeve compression clamp, thereby clamping and securing the PEEK sleeve.

[0011] Furthermore, a platform is cut into the outer wall of the adapter sleeve on which the through hole is opened, and the through hole is arranged on the platform.

[0012] Furthermore, the FC ferrule adapter II is provided with a PEEK sleeve center hole for the PEEK sleeve to pass through.

[0013] Furthermore, the diameter of the central hole of the PEEK sleeve is adapted to the diameter of the PEEK sleeve. This prevents the central hole from being too large, causing the PEEK sleeve to become too loose within the FC ferrule adapter II, thereby misaligning the PEEK sleeve with other components. It also prevents the central hole from being too small, preventing the PEEK sleeve from passing through the FC ferrule adapter II.

[0014] Furthermore, the through hole is an annular hole, or a square hole, and its shape is not limited.

[0015] Furthermore, the FC ferrule fixing sleeve, FC connector fastening ring, FC ferrule, FC ferrule adapter I, FC ferrule adapter II, PEEK double-pass sleeve, high-strength outer sheath, PEEK sleeve, and optical fiber are all coaxial with the center hole of the PEEK sleeve when assembled in sequence.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1. Compared with the prior art, the present invention utilizes two threaded connectors, FC ferrule adapter I and FC ferrule adapter II, to create a high-strength mechanical connection in the fiber-optic FC converter designed in this invention, protecting the PEEK sleeve and optical fiber from axial tension and radial compression. An observation window is also provided in FC ferrule adapter I to observe whether the PEEK sleeve is pressing on the optical fiber during tightening, thereby adjusting the tension of the optical fiber.

[0018] 2. Compared with the existing technology, by cooperating with the PEEK sleeve tightening mouth, clamping the PEEK sleeve, tightening the connection stud, and rotating the connection with the tightening connection screw mouth, the PEEK sleeve tightening clamp is pressed, thereby clamping and fixing the PEEK sleeve, so that the PEEK sleeve can be clamped inside the optical fiber FC converter.

[0019] 3. Compared with the prior art, the diameter of the center hole of the PEEK sleeve is adapted to the tube diameter of the PEEK sleeve. Setting the diameter of the center hole of the PEEK sleeve to adapt to the tube diameter of the PEEK sleeve prevents the center hole from being too large and the PEEK sleeve from being too loose in the FC ferrule adapter II, causing the PEEK sleeve and other components to be not on the same axis, and prevents the center hole from being too small and the PEEK sleeve from passing through the FC ferrule adapter II.
