Description

Technical Field

[0001] The invention relates to the technical field of optical communications, and in particular to a high optical power density optical connector. Background Art

[0002] A multi-channel fiber optic connector is a connector that can connect multiple fiber channels at the same time. It is mainly used in application scenarios where multiple fiber optic signals need to be transmitted simultaneously. This type of connector is usually used in data centers, high-speed network connections, fiber to the home (FTTH), high-density fiber optic wiring and other fields. Multi-channel fiber optic connectors can reduce the number of connectors, simplify the installation and maintenance process, and improve signal transmission efficiency. Common multi-channel fiber optic connectors include LC MTP, LC MPO, MTP, MPO and other types. The number of optical fibers supported by these connectors ranges from 8 to 144 cores. Each connector has its specific application characteristics and advantages, and the selection should be determined based on the specific application requirements;

[0003] In today's communications field, the traditional fiber optic connection method is often highly dependent on manual precise alignment and manual fixation in actual operation. Specifically, when performing fiber optic connection, the operator needs to rely on his own experience and skills, through naked eye observation and manual operation, to ensure that the end face of the optical fiber can be accurately aligned. However, this method of relying on manual operation has many disadvantages that are difficult to overcome. First, from the perspective of time cost, the process of manual precise alignment and manual fixation is extremely time-consuming. The operator needs to spend a lot of time and energy to repeatedly adjust the position and angle of the optical fiber to achieve the best alignment state. Secondly, this method is also very laborious. The operator needs to maintain a high degree of concentration and meticulous operation for a long time, and the spirit is always in a tense state. This not only puts extremely high demands on the professional skills of the operators, but also brings them great physical and mental pressure. Long-term operation may cause fatigue and decreased vision of the operators, which in turn affects the accuracy and stability of the operation.

[0004] In summary, the traditional fiber optic connection method is overly dependent on manual precision alignment and manual fixation, which is time-consuming and labor-intensive, and difficult to ensure connection accuracy and stability. These problems will inevitably have an adverse impact on the quality of fiber optic signal transmission;

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention designs an adaptive alignment component, which drives the two optical fiber bodies to move relative to each other through a bidirectional screw rod to ensure that the optical fiber end faces can be accurately aligned with the connector body connection port. This design effectively overcomes the errors caused by relying on manual alignment in traditional optical fiber connection methods, and significantly improves the accuracy of optical fiber docking.

The locking assembly adopts a quick locking and unlocking design, which is not only convenient for operation but also ensures the stability and reliability of the connection. The stable connection state can effectively prevent signal interruption and transmission quality degradation, thereby improving the reliability of the entire communication system.

[0022] 4. The present invention introduces heat dissipation fins on the surface of the connector to optimize the heat dissipation performance. During high-power transmission, the connector body will generate a large amount of heat. Excessive temperature will affect the performance and life of the optical fiber. The design of the heat dissipation fins can effectively reduce the temperature rise of the connector and keep it within a suitable operating temperature range, thereby extending the service life of the equipment and improving the stability of the system.

The dust screen 5 is mainly used to prevent dust or foreign matter from entering the inner cavity of the heat sink. Two rotating shafts 501 are fixedly connected to the top of the connector body 1. The surfaces of the two rotating shafts 501 are rotatably connected to the limiting plates 502. By setting the limiting plates 502, the rotating limiting plates 502 can limit the dust screen 5. The grid size of the dust screen 5 is 0.1 mm × 0.1 mm. The dust screen 5 is made of stainless steel. One end of the first return spring 304 is fixedly connected to one end of the limiting ring 303, and the other end of the first return spring 304 is fixedly connected to one end of the inner cavity of the shell 3. There are three second return springs 308, one ends of the three second return springs 308 are fixedly connected to the bottom ends of the push rod 306 and the second clamping block 307 respectively, and the other ends of the three second return springs 308 are fixedly connected to the bottom end of the shell 3, and the surface of the knob 203 and the opposite surfaces of a pair of clamping blocks 301 are provided with anti-slip textures, and the anti-slip textures are used to increase the friction force to achieve an anti-slip effect. The thickness of the push plate 302 is 2 mm, and the material of the push plate 302 is nylon. The inner diameter of the limit ring 303 is 6 mm, and the material of the limit ring 303 is stainless steel. The wire diameter of the first return spring 304 is 0.5 mm, and the wire diameter of the second return spring 308 is 0.8 mm. The materials of the first return spring 304 and the second return spring 308 are spring steel.

[0035] When in use, first place the two optical fiber bodies on the opposite surfaces of the two groups of a pair of clamping blocks 301 in sequence, and then press the two push plates 302 at the same time, so that the two push plates 302 drive the pair of clamping blocks 301 to move relatively, and clamp the optical fiber body. The two push plates 302 will compress the first return spring 304 during the movement, and at the same time, the pair of clamping blocks 301 will drive the first clamping block 305 to move during the movement. At this time, the inclined surface of the surface of the first clamping block 305 will squeeze the inclined surface of the inner cavity of the second clamping block 307, so that the second clamping block 307 moves downward and squeezes the second return spring 308, so that the second return spring 308 is compressed. When 301 clamps the optical fiber body, the second return spring 308 will drive the second clamping block 307 to move upward, so that the inner cavity plane of the second clamping block 307 is in contact with the plane of the surface of the first clamping block 305, and the pair of clamping blocks 301 are limited. After the optical fiber body is clamped, the knob 203 is rotated to make the knob 203 drive the bidirectional screw rod 201 to rotate. The rotation of the bidirectional screw rod 201 drives the two connecting plates 204 to move relative to each other along the guide direction of the guide rod 202. The two connecting plates 204 move relative to each other, thereby driving the two groups of pairs of clamping blocks 301 and the two optical fiber bodies to move relative to each other, so that the two optical fiber bodies are connected to the connector body 1.

[0036] When it is necessary to loosen the optical fiber body with a pair of clamping blocks 301, first push the push rod 306 downward. The downward movement of the push rod 306 will drive the second clamping block 307 to move downward and compress the second reset spring 308, so that the inner cavity of the second clamping block 307 no longer clamps the surface of the first clamping block 305. At this time, the first reset spring 304 will drive the two push plates 302 and the pair of clamping blocks 301 to reset, thereby loosening the optical fiber body. When the optical fiber body is loosened, release the push rod 306. At this time, the push rod 306 and the second clamping block 307 move upward under the action of the extension force of the second reset spring 308, so that the inner cavity of the second clamping block 307 clamps the surface of the first clamping block 305 again.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
