Detailed Description

The present application will be described in further detail below with reference to the accompanying drawings.

The embodiment of the application discloses an optical communication connector.

Example 1

Referring to fig. 1, an optical communication connector includes the following main components: an optical fiber 1, a connector 3 and a lens group 2. The lens group 2 is fixedly connected with one side of the connecting piece 3, so that the stability between the lens group 2 and the connecting piece 3 is ensured. The optical fiber 1 is inserted into the connector 3, and the access end of the optical fiber 1 is opposite to the lens group 2, so that the function of signal transmission is realized. The lens group 2 plays roles of focusing and adjusting the optical signals, and can focus the optical signals, so that the optical signals are more concentrated and have larger intensity.

Referring to fig. 2, the connector 3 has a horn-shaped structure, a through hole 31 is formed in the middle of the connector, the lens group 2 is connected to a side with a smaller opening, and the optical fiber 1 is inserted into the through hole 31 from a side with a larger opening. The trumpet arrangement has two main considerations, firstly, the trumpet configuration of the connector 3 helps to concentrate and guide the optical signal from the optical fiber 1 to the lens group 2, improving the optical coupling efficiency. When an optical signal is transmitted from the optical fiber 1 to the connector 3, the horn structure may focus the optical signal inside the connector 3 and direct it into the lens group 2. The loss of the optical signal in the transmission process can be reduced, and the transmission efficiency and performance of the optical fiber 1 can be improved. Secondly, the larger opening on the side facing away from the lens group 2 facilitates the insertion, docking and fixing operations of the optical fiber 1. Through the larger opening, the optical fiber 1 can be easily inserted into the through hole 31 of the connector 3 and docked with the lens group 2. This design makes the installation of the optical fiber 1 more convenient and quick and ensures a stable connection between the optical fiber 1 and the connector 3.

The trumpet-shaped structure also allows for different sizes and numbers of bundles of optical fibers 1 to be easily accessed and secured, increasing the versatility and flexibility of the connector. Since the opening of the horn structure can accommodate bundles of optical fibers 1 of different sizes, the connector 3 can be adapted to a variety of different optical fiber 1 types and connection requirements.

In addition, the larger opening also aids in heat dissipation from the connector. In high power optical transmission, the optical fiber 1 generates heat, and the larger opening can provide better heat dissipation effect, so that signal loss and equipment failure caused by overheating of the optical fiber 1 are avoided.

An adjusting mechanism is arranged in the through hole 31 of the connecting piece 3, and the access end of the optical fiber 1 can be opposite to the lens group 2 through adjustment. Referring to fig. 3, the adjusting mechanism includes a fixing plate 41 and an elastic member 42, where the center of the fixing plate 41 is perforated for the optical fiber 1 to pass through, and the fixing plate 41 is perpendicular to the length direction of the through hole 31, and the elastic member 42 is a spring in this embodiment, and elastic members with the same effect are all used, the elastic member 42 is in a cross shape and is respectively connected with the four directions of the fixing plate 41, and the other end of the elastic member 42 is fixed with the inner wall of the through hole 31 of the connecting member 3.

The elastic member 42 can realize the resetting of the fixing plate 41, and readjustment when the optical fiber 1 is replaced is facilitated. The four directions of connecting the fixing plates 41 respectively can balance the forces received by the fixing plates 41, and avoid the damage or deformation risk of the fixing plates 41 caused by excessive force in a certain direction. In practice, a plurality of elastic members 42 may be provided as needed, but the elastic members 42 are secured to both ends of the coaxial line of the fixing plate 41.

By adjusting the degree of tightness between the fixing plate 41 and the elastic member 42, fine positional adjustment of the fixing plate 41 can be performed to achieve a minute adjustment of the access end of the optical fiber 1. Such fine tuning ensures perfect alignment of the optical axis of the optical fiber 1 with the optical axis of the lens group 2, thereby minimizing optical signal attenuation and reflection, and maintaining the strength and quality of the signal to the maximum extent, which is important for applications requiring high quality optical signal transmission, such as optical communication, optical fiber 1 sensing, and lasers.

Referring to fig. 2, a limiting plate 32 is further disposed in the through hole 31 of the connector 3, and the limiting plate 32 includes a first limiting plate 321 and a second limiting plate 322, which are respectively located at both sides of the fixing plate 41. Wherein the first limiting plate 321 is arranged at a side facing away from the lens group 2. The fixed plate 41 is of a circular plate structure and is fixedly connected with the inner wall of the through hole 31 of the connecting piece 3, the fixed plate 41 is clamped by the first limiting plate 321 and the second limiting plate 322, the moving range of the fixed plate 41 is effectively limited, the fixed plate 41 cannot deviate along the length direction of the through hole 31, the relative position stability of the access end of the optical fiber 1 is ensured, the optical signal loss or other performance problems caused by position deviation are reduced, and the reliability and stability of the whole optical communication system are further improved.

In addition, the presence of the limiting plate 32 helps to maintain the perpendicularity of the fixing plate 41, protecting the optical fiber 1 from excessive bending or stress, thereby reducing damage or performance degradation of the optical fiber 1. The hollow portion of the limiting plate 32 reserves a space for adjusting the optical fiber 1, so that the optical fiber 1 can be freely adjusted within the circumferential range of the through hole 31. Therefore, the position of the optical fiber 1 in the connecting piece 3 can be adjusted more flexibly, and the free movement of the optical fiber 1 in the circumferential range can be ensured, so that the accurate requirements of different application scenes on the position of the optical fiber 1 can be met.

In addition, a locking seat 33 is disposed on one side of the first limiting plate 321 facing away from the lens group 2, and two locking seats 33 are symmetrically disposed in the present application. The locking seat 33 is provided with a locking member 34, and in the present application, a locking bolt is used as the locking member 34. With reference to fig. 3, a relief hole is correspondingly formed in the fixing plate 41 for the passage of the locking member 34. When the position of the optical fiber 1 needs to be adjusted, the locking member 34 rotates to release the fixing plate 41, so that the fixing plate 41 can be adjusted, and the position of the optical fiber 1 is adjusted. After the adjustment is completed, the locking piece 34 is rotated to be abutted against the fixing plate 41 and press the fixing plate 41 for locking and positioning. Is flexible and reliable, can ensure the correct positioning of the optical fiber 1, and stably fix the optical fiber 1. And effectively prevents the optical fiber 1 from loosening and vibrating during use. Thus, signal disruption or other performance problems due to unexpected movement or deflection are avoided, further improving the stability and reliability of the system.

By the cooperation of the locking seat 33 and the locking piece 34, the position of the optical fiber 1 can be precisely controlled, the stability of the optical fiber can be maintained, and the normal operation of the optical communication system can be ensured. Meanwhile, the optical fiber device has high adjustability, and the optical fiber 1 can be finely adjusted and positioned according to actual requirements so as to meet the requirements of different application scenes.

Referring to fig. 2 and 4, a clamping mechanism 5 is provided on the side of the connecting piece 3 facing away from the lens package 2. The clamping mechanism 5 comprises two oppositely arranged clamping ends 51, each clamping end 51 being provided with a telescopic push rod 52 on the side facing away from the optical fiber 1. By controlling the expansion and contraction of the push rod 52, the clamping and release of the optical fiber 1 by the clamping end 51 can be controlled.

The clamping mechanism 5 further clamps and fixes the optical fiber 1, controls the feeding degree of the optical fiber 1, controls the distance between the access end of the optical fiber 1 and the lens group 2, ensures stable transmission and accurate reception of signals, and improves the optical quality of light in the transmission process.

The push rod 52 provided with the clamping end 51 has an adjustable function, and a user can adjust the clamping force according to the requirement, so that the clamping mechanism 5 can process optical fibers 1 with different diameters or types, and enough flexibility and adaptability are provided.

Referring to fig. 4, the clamping end 51 is designed to be curved, to conform to the optical fiber 1 and provide a uniform distribution of pressure. Compared to other designs of the clamping ends 51, the curved clamping ends 51 can avoid damage or stress concentration to the optical fiber 1 caused by concentrated pressure points, thereby reducing the risk of breakage of the optical fiber 1. This design can make the area of contact between the clamping end 51 and the optical fiber 1 larger, provide a more uniform clamping force, and reduce friction and abrasion of the clamping end 51 to the surface of the optical fiber 1 while ensuring the clamping effect.

Second, since the arcuate clamping end 51 can better conform to the surface of the optical fiber 1, a more reliable clamping effect is provided. This clamping effect ensures the stability and reliability of the optical fiber 1 in the connector 3, thereby improving the quality and reliability of the optical transmission.

Referring to fig. 2 and 4, in addition to the arcuate clamping end 51, the present design provides serrated protrusions 53 on the clamping end 51. The serrations 53 can increase the friction between the clamping end 51 and the optical fiber 1, thereby improving the clamping force. By increasing the clamping force, it is ensured that the optical fiber 1 can be more stably fixed in the connector 3, reducing the probability of mismatch or loosening. But also helps to prevent rotation or sliding of the optical fiber 1 in the connector 3. The shape of the protrusion 53 may provide additional resistance, making the optical fiber 1 more difficult to move or twist, may ensure that the position of the optical fiber 1 in the connector 3 is fixed, and avoids errors or losses in signal transmission.

Furthermore, an optical power detector 6 is additionally provided on the side of the lens package 2 facing away from the connection piece 3. The optical power detector 6 is able to feed back information on the alignment of the optical fiber 1 with the lens on-the-fly. By detecting the change of the optical power, whether the optical fiber 1 is aligned with the lens group 2 or not can be rapidly confirmed, and corresponding adjustment is performed, so that the installation and adjustment processes are simplified.

The implementation principle of the embodiment 1 is as follows:

fine tuning of the position and angle of the optical fiber 1 can be achieved by controlling the adjusting assembly 4 in the connector 3. The adjusting assembly 4 includes a fixing plate 41 and an elastic member 42, and by adjusting the degree of tightness therebetween, the position of the optical fiber 1 can be precisely adjusted, thereby improving the efficiency and quality of optical signal transmission, reducing signal loss and distortion, and thus reducing the failure rate.

In addition to the adjustment assembly 4, a stop plate 32, a retaining member 34 and a clamping arrangement are used to fix the position of the optical fiber 1. The stopper plate 32 can restrict the movement range of the fixing plate 41 and ensure a stable position thereof. The locking member 34 can then firmly secure the optical fiber 1 against accidental movement or misalignment, which can result in signal interruption or other performance problems. The clamping arrangement may provide additional support and protection to ensure that the optical fibre 1 is in the correct position.

For easier installation and adjustment, an optical power detector 6 is also provided. The optical power detector 6 is able to identify alignment problems between the optical fiber 1 and the lens group 2 and provide immediate feedback. If the optical fiber 1 is not properly aligned, the optical power may be reduced, prompting the operator to make an adjustment. This simplifies the installation and adjustment process, making it more intuitive and quick.

Example 2

Referring to fig. 5, the present embodiment is different from embodiment 1 in that a plurality of optical fibers 1 are employed in the present embodiment, the optical fibers 1 are circumferentially distributed around the same axis, and the access ends of the optical fibers 1 are located on the same plane.

The implementation principle of the embodiment 2 is as follows:

The optical fibers 1 are circumferentially distributed around the same axis, so that more optical fibers 1 can be integrated in a limited space, and high-density optical communication connection is realized. Meanwhile, when the optical fibers 1 are circumferentially distributed around the same axis, the path length and the optical characteristics of each optical fiber 1 tend to be consistent, and the uniform distribution can help to keep the uniformity of signal transmission, reduce the signal loss and distortion between the optical fibers 1, and is very important for the requirement of stable and high-quality optical signal transmission.

Secondly, placing the access ends of all the optical fibers 1 on the same plane helps to achieve a uniform alignment and efficient optical coupling between the optical fibers 1 and reduces the possibility of signal interruption or performance problems due to poor contact or misalignment to achieve an optimal optical coupling effect.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
