Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber technology, specifically a dustproof and waterproof protection device for optical fiber connectors. Background Technology
[0002] Optical fiber is short for optical waveguide fiber. It is a type of fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle is "total internal reflection of light". The fine optical fiber is encapsulated in a plastic sheath, which allows it to bend without breaking. Typically, the transmitting device at one end of the optical fiber uses a light-emitting diode or a laser beam to transmit light pulses to the optical fiber, while the receiving device at the other end of the optical fiber uses a photosensitive element to detect the pulses.
[0003] In fiber optic applications, two optical fibers are connected using connectors. However, existing fiber optic connectors are prone to breakage at the connection point when suddenly pulled, which can affect the transmission process. Furthermore, after prolonged use, dust or moisture can enter the connector through gaps, affecting its lifespan and connection stability. Utility Model Content
[0004] Technical problems to be solved
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a dustproof and waterproof protection device for fiber optic connectors. The connection protection mechanism enhances the connection strength of the fiber optic connector and prevents the fiber from being pulled off the connection due to sudden tension. The sealing mechanism pushes the waterproof sealing strip to both sides and slides it inside the protective cover until it blocks the connection gap between the protective cover and the protective shell, thereby preventing moisture from entering the interior of the protective device through the gap and affecting the service life of the connection.
[0006] Technical solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a dustproof and waterproof protection device for an optical fiber connector, comprising an optical fiber conductor and a connector, wherein the connector is fixedly connected at the connection point of the two optical fiber conductors, a connection protection mechanism is provided on the outer side of the connector, and sealing rings are provided at both ends of the connection protection mechanism, the inner walls of the sealing rings are tightly attached to the outer side of the optical fiber conductors, and a protective shell is fixedly connected to the outer side of the sealing rings, a protective cover is movably connected to one side of the protective cover via a rotating shaft, and a sealing mechanism is movably connected inside the protective cover.
[0008] The aforementioned connection protection mechanism includes a limiting seat, an extension cover, a return spring, and a linkage bar. There are two limiting seats and two extension covers, which are movably connected to the top of the limiting seats via a rotating shaft. The opposite sides of the two limiting seats and the two extension covers are movably connected via a return spring. The surfaces of the limiting seats and the extension covers are provided with sliding grooves, and the two ends of the linkage bar are slidably connected to the inside of the sliding grooves.
[0009] As described above, both the limiting seat and the extension cover are semi-circular rings. The bottom end of one of the limiting seats is fixedly connected to the inside of the protective shell. The connector is engaged with the inner side of the limiting seat and the extension cover. The other end of the other limiting seat is fixedly connected to a locking block.
[0010] As described above, a fixing block is fixedly connected to one end of the extension cover near the locking block, and a limiting strip is movably connected inside the fixing block via a rotating shaft. The bottom end of the limiting strip is hook-shaped, and a compression spring is fixedly connected to the inner side of the other end of the limiting strip. The other end of the compression spring is fixedly connected to the outer side of the extension cover.
[0011] The sealing mechanism described above includes a control block, a connecting spring, a drive bar, and a waterproof sealing strip. The drive bar is movably connected to both sides of the control block via a rotating shaft, and the connecting spring is fixedly connected to the top of the control block. The waterproof sealing strip is fixedly connected to the side of the drive bar away from the control block.
[0012] As described above, the waterproof sealing strip is composed of a sponge and a sealing strip, and the waterproof sealing strip is arc-shaped, and the waterproof sealing strip is tightly attached to the inner wall of the protective cover.
[0013] As described above, the end of the connecting spring away from the control block is fixedly connected to the inside of the protective cover, and when the protective cover and the protective shell overlap, the control block is located directly above the linkage bar.
[0014] Beneficial effects:
[0015] Compared with existing technologies, this dustproof and waterproof protection device for fiber optic connectors has the following advantages:
[0016] I. This utility model, through its connection protection mechanism, opens the extension covers together and simultaneously pulls the movable limiting seat to one end. At this time, the return spring is stretched, and the connector is placed inside the limiting seat. When the limiting seat is released, the return spring reacts to the limiting seat and the extension cover, causing the connector to engage inside the limiting seat. Then, the extension cover is flipped inward and moved to the top of the limiting seat. Subsequently, the limiting strip is pressed so that its bottom end is raised, and then the compression spring is compressed. When the limiting seat and the extension cover are completely closed, the limiting strip is released. At this time, the compression spring reacts to the limiting strip so that its bottom end hooks onto the bottom end of the locking block, thereby enhancing the connection strength of the optical fiber connector and preventing the optical fiber from being suddenly pulled and causing the connection to detach.
[0017] Second, through the sealing mechanism set up in this utility model, when the protective cover and the protective shell are closed together, the linkage bar pushes the control block upward, the connecting spring contracts, and at the same time the drive bar pushes the waterproof sealing strip to both sides to slide inside the protective cover until it blocks the connection gap between the protective cover and the protective shell laterally. This helps to prevent water vapor from entering the interior of the protective equipment through the gap and affecting the service life of the connection.
[0018] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figure 1-4As shown, this utility model provides a technical solution: a dustproof and waterproof protection device for an optical fiber connector, including an optical fiber conductor 1 and a connector 2. The connector 2 is fixedly connected to the connection point of two optical fiber conductors 1. A connection protection mechanism 3 is provided on the outside of the connector 2, and sealing rings 4 are provided at both ends of the connection protection mechanism 3. The inner walls of the sealing rings 4 are tightly attached to the outside of the optical fiber conductor 1, and a protective shell 5 is fixedly connected to the outside of the sealing rings 4. A protective cover 6 is movably connected to one side of the protective shell 5 through a rotating shaft, and a sealing mechanism 7 is movably connected inside the protective cover 6.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the connecting protection mechanism 3 includes a limiting seat 301, an extension cover 302, a return spring 303, and a linkage bar 304. Two limiting seats 301 and two extension covers 302 are provided and movably connected to the top of the limiting seats 301 via a rotating shaft. The opposite sides of the two limiting seats 301 and the two extension covers 302 are movably connected by the return spring 303. The surfaces of the limiting seats 301 and the extension covers 302 are each provided with a sliding groove 305, and both ends of the linkage bar 304 are slidably connected inside the sliding groove 305. Both the limiting seats 301 and the extension covers 302 are semi-circular. The ring has one limiting seat 301 whose bottom end is fixedly connected to the inside of the protective shell 5, the connector 2 is engaged with the inner side of the limiting seat 301 and the extension cover 302, and the other end of the limiting seat 301 is fixedly connected to the locking block 8. The end of the extension cover 302 near the locking block 8 is fixedly connected to the fixing block 9, and the inside of the fixing block 9 is movably connected to the limiting strip 10 through the rotating shaft. The bottom end of the limiting strip 10 is opened in the shape of a barb, and the inner side of the other end of the limiting strip 10 is fixedly connected to the compression spring 11. The other end of the compression spring 11 is fixedly connected to the outer side of the extension cover 302.
[0027] By opening the extension cover 302 together and simultaneously pulling the movable limiting seat 301 to one end, the return spring 303 is stretched, and the connector 2 is placed inside the limiting seat 301. When the limiting seat 301 is released, the return spring 303 reacts to the limiting seat 301 and the extension cover 302, causing the connector 2 to engage inside the limiting seat 301. Then, the extension cover 302 is flipped inward and moved to the top of the limiting seat 301. Then, the limiting strip 10 is pressed so that its bottom end is raised. Next, the compression spring 11 is compressed. When the limiting seat 301 and the extension cover 302 are completely closed, the limiting strip 10 is released. At this time, the compression spring 11 reacts to the limiting strip 10 so that its bottom end hooks onto the bottom end of the locking block 8, which helps to enhance the connection strength of the optical fiber connector 2 and prevents the optical fiber from being suddenly pulled and causing the connection to fall off.
[0028] like Figure 1 , Figure 2 and Figure 4As shown, the sealing mechanism 7 includes a control block 701, a connecting spring 702, a drive bar 703, and a waterproof sealing strip 704. The drive bar 703 is movably connected to both sides of the control block 701 via a rotating shaft, and the connecting spring 702 is fixedly connected to the top of the control block 701. The waterproof sealing strip 704 is fixedly connected to the side of the drive bar 703 away from the control block 701. The waterproof sealing strip 704 is composed of sponge and sealing strip, and the waterproof sealing strip 704 is arc-shaped. The waterproof sealing strip 704 is tightly attached to the inner wall of the protective cover 6. The end of the connecting spring 702 away from the control block 701 is fixedly connected to the inside of the protective cover 6. When the protective cover 6 and the protective shell 5 overlap, the control block 701 is located directly above the linkage bar 304.
[0029] During the closing process of the protective cover 6 and the protective shell 5, the linkage bar 304 pushes the control block 701 upward, the connecting spring 702 retracts, and at the same time the drive bar 703 pushes the waterproof sealing bar 704 to slide inside the protective cover 6 until it blocks the connection gap between the protective cover 6 and the protective shell 5 laterally. This helps to prevent moisture from entering the interior of the protective equipment through the gap and affecting the service life of the connection.
[0030] Working principle: In use, open the extension cover 302 together and pull the movable limiting seat 301 to one end. At this time, the return spring 303 is stretched, and the connector 2 is placed inside the limiting seat 301. When the limiting seat 301 is released, the return spring 303 acts on the limiting seat 301 and the extension cover 302 to lock the connector 2 inside the limiting seat 301. Next, flip the extension cover 302 inward and move it to the top of the limiting seat 301. Then press the limiting strip 10 to make its bottom end lift up, and then squeeze... When spring 11 contracts, the limiting seat 301 and extension cover 302 are fully closed, and the limiting strip 10 is released. At this time, the compression spring 11 reacts to the limiting strip 10, causing its bottom end to hook onto the bottom end of the locking block 8, and the protective cover 6 is closed. During the process of the protective cover 6 and the protective shell 5 closing each other, the linkage strip 304 pushes the control block 701 upward, the connecting spring 702 contracts, and at the same time the drive strip 703 pushes the waterproof sealing strip 704 to both sides to slide inside the protective cover 6 until it blocks the connection gap between the protective cover 6 and the protective shell 5 laterally.

Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
