Description

Technical Field

[0001] This utility model relates to the field of optical filter technology, specifically to a plug-in optical filter. Background Technology

[0002] A pluggable optical filter is an optical device that combines filtering functionality with plug-and-play features. It is mainly used in optical fiber communication networks. It features miniaturization, low cost, and ease of installation and operation, and can meet the needs of modern communication networks for high efficiency and convenience.

[0003] Plug-in optical filters typically include a male front connector, a female rear connector, and an optical filter core. The male front connector and female rear connector are used by mating together or by connecting to other devices via plugs. Existing plug-in optical filters do not have the function of fixing and protecting the male front connector and female rear connector, which makes the male front connector and female rear connector prone to falling off during long-term use after being connected to other devices, reducing the stability of the plug-in optical filter. Therefore, those skilled in the art provide a plug-in optical filter to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a pluggable optical filter to solve the problems mentioned in the above-mentioned technologies.

[0005] This utility model provides the following technical solution: a plug-in optical filter, including an optical filter body, wherein a female rear seat and a male front seat are respectively provided at both ends of the outer wall of the optical filter body, and protective mechanisms for protecting the female rear seat and the male front seat are respectively provided at both ends of the optical filter body near the female rear seat and the male front seat.

[0007] As a preferred embodiment of the above technical solution, a bidirectional lead screw is rotatably installed inside the top of the opening of both sets of protective shells. Both ends of the surface of the two sets of bidirectional lead screws are threaded with a threaded sleeve seat. One end of the two sets of bidirectional lead screws is fixedly connected to a throttle handle. Both throttle handles are located on one side of the outer wall of the protective shell.

[0008] As a preferred embodiment of the above technical solution, the bottom ends of both sets of threaded sleeve seats are fixedly connected with connecting rods, and the two sets of connecting rods are slidably arranged at both ends inside the opening of the protective shell, with the two sets of connecting rods arranged in opposite directions.

[0009] As a preferred embodiment of the above technical solution, a sliding groove is provided inside the bottom end of the opening of both sets of protective shells, and a sliding seat is slidably installed inside the sliding grooves of both sets. The top ends of the two sets of sliding seats are respectively fixedly connected to the ends of the two sets of connecting rods away from the thread sleeve seat.

[0010] As a preferred embodiment of the above technical solution, an arc-shaped clamp is fixedly installed on one side of each of the two sets of connecting rods, and a folding plate is hinged to the side of each of the two sets of connecting rods away from the arc-shaped clamp. The ends of the two sets of folding plates away from the two sets of connecting rods are respectively hinged to the inner wall of the opening of the protective shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention first electrically connects the female rear connector and the male front connector to the plug of an external device. Then, the protective shell on the protective mechanism protects the plug of the female rear connector and the male front connector from the external device. The arc-shaped clamp on the protective mechanism clamps and fixes the wires connected to the plug of the external device.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figures 1-4 As shown, this utility model provides a technical solution: a plug-in optical filter, including an optical filter body 1, with a female rear seat 2 and a male front seat 3 respectively provided at both ends of the outer wall of the optical filter body 1.

[0021] When using the optical filter body 1, first connect the female rear connector 2 and the male front connector 3 to the plug of the external device. The two sets of protective shells 402 protect the female rear connector 2 and the male front connector 3 from the plug of the external device.

[0022] As one implementation method in this embodiment, please refer to Figure 1 , Figure 3 and Figure 4 As shown, protective mechanisms 4 for protecting the rear seat 2 and the front seat 3 of the optical filter body 1 are respectively provided at both ends of the optical filter body 1 near the rear seat 2 and the front seat 3 of the optical filter body 1. The two sets of protective mechanisms 4 include two sets of mounting sleeves 401 fitted on both ends of the outer wall of the optical filter body 1. A protective shell 402 is fixedly installed at the end of each set of mounting sleeves 401 away from the optical filter body 1. A bidirectional lead screw 403 is rotatably installed inside the top of the opening of each set of protective shells 402. A threaded sleeve seat 404 is threaded onto both ends of the surface of each set of bidirectional lead screws 403. A throttle 405 is fixedly connected to one end of each set of bidirectional lead screws 403. Both throttles 405 are located on one side of the outer wall of the protective shell 402. A connecting rod 406 is fixedly connected to the bottom end of each set of threaded sleeve seats 404. The two connecting rods 406 are slidably arranged at both ends of the inner side of the opening of the protective shell 402. The two connecting rods 406 are arranged in opposite directions.

[0023] Manually rotate two sets of handles 405. The handles 405 drive the bidirectional lead screw 403 to rotate. The bidirectional lead screw 403 drives the threaded sleeve seat 404 on the surface to move in opposite directions. The threaded sleeve seat 404 drives the connecting rod 406 to slide at both ends inside the opening of the protective shell 402. The connecting rod 406 drives the slide seat 408 to slide inside the slide groove 407. At the same time, the connecting rod 406 drives the arc-shaped clamp 409 fixedly installed on one side to clamp and fix the wire connected to the plug of the external equipment. This ensures the stability of the connection between the plug of the external equipment and the female rear seat 2 and the male front seat 3, and avoids poor connection caused by wire shaking.

[0024] As one implementation method in this embodiment, please refer to Figure 1 Figure 2 and Figure 4As shown, the bottom of the openings of the two sets of protective shells 402 are provided with sliding grooves 407. Sliding blocks 408 are slidably installed inside the two sets of sliding grooves 407. The tops of the two sets of sliding blocks 408 are respectively fixedly connected to the ends of the two sets of connecting rods 406 away from the threaded sleeve seat 404. Arc-shaped clamps 409 are fixedly installed on one side of the two sets of connecting rods 406. Folding plates 410 are hinged to the sides of the two sets of connecting rods 406 away from the arc-shaped clamps 409. The ends of the two sets of folding plates 410 away from the two sets of connecting rods 406 are respectively hinged to the inner wall of the opening of the protective shell 402.

[0025] The folding plate 410 fits perfectly against the inner wall of the opening of the protective shell 402, sealing off the opening and effectively preventing external dust and impurities from entering the protective shell 402 and affecting the plug-in optical filter. Simultaneously, the folding plate 410 avoids the problem of the connecting rod 406 occupying too much space during movement, improving the practicality of the plug-in optical filter. Furthermore, the sliding groove 407 and sliding base 408 guide and limit the movement of the connecting rod 406, making its movement more stable and further improving the stability of the plug-in optical filter.

[0026] Working principle: When using the optical filter body 1, firstly, the female rear connector 2 and the male front connector 3 are electrically connected to the plug of the external device. Two sets of protective shells 402 protect the female rear connector 2 and the male front connector 3 from the plug of the external device. Then, the user manually rotates two sets of handles 405. The handles 405 drive the bidirectional lead screw 403 to rotate. The bidirectional lead screw 403 drives the threaded sleeve seat 404 on the surface to move in opposite directions. The threaded sleeve seat 404 drives the connecting rod 406 to slide at both ends inside the opening of the protective shell 402. The connecting rod 406 drives the slide seat 408 to slide inside the slide groove 407. At the same time, the connecting rod 406 drives the arc-shaped clamp 409 fixed on one side to clamp and fix the wire connected to the plug of the external device, thereby ensuring the stability of the connection between the plug of the external device and the female rear connector 2 and the male front connector 3, and avoiding poor connection due to wire shaking.

[0027] After the arc-shaped clamp 409 clamps the female rear seat 2 and the male front seat 3, the folding plate 410 is completely attached to the inner wall of the opening of the protective shell 402, sealing and blocking the opening of the protective shell 402. This effectively prevents external dust and impurities from entering the interior of the protective shell 402 and affecting the plug-in optical filter. At the same time, the folding plate 410 avoids the problem of the connecting rod 406 occupying a large space when moving, improving the practicality of the plug-in optical filter. In addition, the sliding groove 407 and the sliding seat 408 can guide and limit the movement of the connecting rod 406, making the connecting rod 406 move more smoothly and further improving the stability of the plug-in optical filter.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
