Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber modems, and more specifically, to an anti-interference portable optical fiber modem. Background Art

[0002] Fiber optic modems are devices used in fiber optic communication systems. They are mainly used to convert electrical signals into optical signals (modulation), or optical signals into electrical signals (demodulation). In fiber optic communication systems, fiber optic modems play a very important role in realizing the transmission and reception of optical signals. Currently, most CAN fiber optic modems on the market are used for a long time, and the connection sockets are generally connected to longer lines. Due to gravity, the plugs are easily loosened, resulting in poor contact at the connection.

[0003] The utility model with announcement number CN213937919U discloses a CAN fiber optic modem. Through a modem body provided, the optical fiber line is quickly connected to the modem body through the plugging of the optical fiber connector and the optical fiber plug interface, and the driving block is pushed by the sliding sleeve action of the driving block and the guide slide rod, so that the L-shaped wire fixing plate is moved to the outside of the modem body. At this time, the wire clamping groove on the lower side of the L-shaped wire fixing plate is clamped on the outside of the fixed tube, and the limiting ring plate is abutted on both sides of the L-shaped wire fixing plate to realize the relative clamping and limiting of the two, so that the electrical plugging of the optical fiber connector and the optical fiber plug interface is more stable, thereby ensuring the stability of the connection structure.

[0004] When the above-mentioned optical fiber modem is in use, the driving block can be firmly limited by pushing the limiting rod into the limiting hole, so that the structure is stable, but it is not convenient to block the electromagnetic radiation interference outside the modem body, which affects the normal operation of the modem body. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides an anti-interference portable optical fiber modem, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-interference portable fiber optic modem, comprising a fiber optic modem main body, three interfaces are opened on the rear side of the fiber optic modem main body, an insulating frame is movably provided on the outer side of the fiber optic modem main body, three sliding rods are fixedly connected to the inner bottom end of the insulating frame, a lead screw is movably connected to the inner bottom end of the insulating frame and located between two of the sliding rods through a bearing, a protective component is provided on the insulating frame, the protective component comprises two insulating baffles and a connecting plate, the front and rear ends of the connecting plate are respectively fixedly connected to the two insulating baffles, the lead screw and the three sliding rods respectively penetrate the two insulating baffles, and the lead screw is threadedly connected to one of the insulating baffles.

[0007] Furthermore, a handle is movably provided on the top of the insulating frame, and the bottom end of the handle is fixedly connected to the screw rod.

[0008] It can be seen that in the above technical solution, it is convenient to drive the screw rod to rotate.

[0009] Furthermore, two limiting plates are movably provided on the top of the inner cavity of the insulating frame, and opposite sides of the two limiting plates are fixedly connected to the two insulating baffles respectively.

[0010] It can be seen that in the above technical solution, the two connecting plates drive the two limiting plates to move downward, and when the two limiting plates are in contact with the inner bottom end of the insulating frame, the two insulating baffles cannot move downward.

[0011] Furthermore, four mounting plates are movably provided at the inner bottom of the insulating frame, and one side of the four mounting plates is respectively fixedly connected to the two insulating baffles.

[0012] It can be seen that in the above technical solution, the two connecting plates drive the four mounting plates to move downward, and the four mounting plates are fixed by four bolts, thereby fixing the insulating frame.

[0013] Furthermore, a fixing frame is fixedly connected to the bottom end of the inner cavity of the insulating frame, and a limiting assembly is arranged on the fixing frame. The limiting assembly includes two L-shaped plates, four springs, four telescopic rods, two plug plates and four insulating plates.

[0014] Furthermore, the four telescopic rods are respectively located inside the four springs, and the two ends of the four springs and the four telescopic rods are respectively fixedly connected to the insulating frame and the two L-shaped plates, and the opposite sides of the two plug plates are respectively fixedly connected to the two L-shaped plates.

[0015] Furthermore, the bottom ends of the four insulating plates are fixedly connected with threaded rods, and the four threaded rods are respectively threadedly connected to the two L-shaped plates.

[0016] It can be seen that in the above technical solution, the insulating plate is rotated to drive the threaded rod to rotate and move away from the L-shaped plate, and the insulating plate is taken out and inspected and replaced.

[0017] Technical effects and advantages of the utility model:

[0018] 1. The utility model pulls out the optical fiber from the interface, and then rotates the handle to drive the screw to rotate. Since the screw is threadedly connected to one of the insulating baffles, and three slide bars limit the rotation of the two insulating baffles, the screw can drive the two insulating baffles to move upward, and at the same time drive the connecting plate to move upward, so that the two insulating baffles and the connecting plate are moved into the insulating frame, further protecting the main body of the optical fiber modem. Similarly, the reverse handle can drive the two insulating baffles and the connecting plate to move downward. The structure is simple, the anti-interference effect is good, and it is easy to use;

[0019] 2. The utility model places the fiber optic modem body in an insulating frame, and the fixing frame and two plug-in plates support the fiber optic modem body. The four springs rebound and drive the two L-shaped plates to move toward each other. The four telescopic rods can limit the deflection of the four springs. The two L-shaped plates can drive the four insulating plates to limit and fix the fiber optic modem body to prevent the fiber optic modem body from shaking. The utility model has a simple structure and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Furthermore, a fixing frame 10 is fixedly connected to the bottom end of the inner cavity of the insulating frame 1, and a limiting assembly 5 is arranged on the fixing frame 10. The limiting assembly 5 includes two L-shaped plates 501, four springs 502, four telescopic rods 503, two plug plates 504 and four insulating plates 505. The four telescopic rods 503 are respectively located inside the four springs 502, and the two ends of the four springs 502 and the four telescopic rods 503 are respectively fixedly connected to the insulating frame 1 and the two L-shaped plates 501, and the opposite sides of the two plug plates 504 are respectively fixedly connected to the two L-shaped plates 501, and the bottom ends of the four insulating plates 505 are fixedly connected with threaded plugs 506, and the four threaded plugs 506 are respectively threadedly connected to the two L-shaped plates 501.
