Description

Technical Field

[0001] The invention relates to the technical field of optical fiber adapter equipment, in particular to an optical fiber adapter with dustproof function for communication transmission. Background Art

[0002] Optical fibers are connected by adapters through the open sleeves inside them to ensure the highest connection performance between optical fiber connectors. They are widely used in optical fiber distribution frames, optical fiber communication equipment, instruments, etc. However, when existing optical fiber adapters are used for a long time, a lot of dust will accumulate on the outside of the adapters. Dust and other tiny particles may accumulate on the outside of the optical fiber adapters, which may have some impact on the optical fiber connection. First, dust may physically block the interface of the optical fiber adapter, making it impossible to insert the optical fiber correctly or causing poor contact, which may cause loss or interruption of signal transmission. Secondly, even if the dust does not completely block the interface, it may introduce additional reflection or scattering between the optical fiber and the adapter, thereby reducing the quality of the signal. When dust enters the adapter, it will have a serious impact on the optical fiber signal. For this reason, a fiber optic adapter with dustproof function for communication transmission is proposed. Summary of the invention

[0003] The object of the present invention is to provide an optical fiber adapter with dustproof function for communication transmission to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is an optical fiber adapter with a dustproof function for communication transmission, comprising a main frame mechanism, the main frame mechanism comprising an adapter body, a dustproof component is arranged outside the adapter body, anti-dropping components are arranged on both sides of the dustproof component, a quick-release component is arranged inside the dustproof component, the dustproof component comprises a dust cover 1, a dust cover 2 is arranged on the right side of the dust cover 1, a plurality of slide grooves are opened on the side corresponding to the inside of the dust cover 1 and the dust cover 2, the plurality of slide grooves are arranged in a circular array, and a plurality of slide grooves located on the left side are slidably connected with slide rods , several of the sliding rods are fixedly connected to the right side with sealing blocks, several of the sealing blocks are L-shaped, and several of the sealing blocks are sleeved with spring rings on the outer surfaces. After the optical fiber plugs are inserted, the sealing blocks will be moved away from each other due to the force of the optical fiber line. When the sealing blocks are moved away from each other, an expansion force will be exerted on the spring ring. At the same time, the spring ring will generate a certain rebound force to drive the sealing block to reset and simply clamp the outer surface of the optical fiber line, thereby achieving a certain sealing effect. At the same time, the spring sheet is inserted into the limiting frame for limiting and fixing, thereby achieving the effect of dustproof sealing again.

[0005] Furthermore, the top and bottom of the dust cover one are fixedly connected with spring pieces, and the top and bottom of the dust cover two are fixedly connected with limiting frames, the interiors of the two limiting frames are in contact with the outer surfaces of the spring pieces, and the front and back sides of the dust cover one and the dust cover two are provided with a plurality of heat dissipation holes, and the plurality of heat dissipation holes are arranged in a vertical array, and the sides of the dust cover one and the dust cover two that are away from each other are fixedly connected with a connecting pipe, and an optical fiber is arranged inside the connecting pipe, so that the dust cover one and the dust cover two are connected and fixed, specifically, the spring piece is inserted into the limiting frame for limiting and fixing, and when the spring piece and the limiting frame are limited and fixed, the dust cover one and the dust cover two are fixedly connected, and at the same time, the plurality of heat dissipation holes have a certain heat dissipation effect for the equipment.

[0006] Furthermore, there are two groups of anti-detachment components, which are symmetrically arranged with the adapter body as the center. The anti-detachment component located on the left side includes a fixed ring, the inner wall of the fixed ring is fixedly connected to the outer surface of the connecting pipe, and the left side of the fixed ring is rotatably connected to a rotating ring. The fixed ring plays a certain supporting role on the rotating ring by being fixedly connected to the outer surface of the connecting pipe.

[0007] Furthermore, a plurality of support rods are rotatably connected to the rotating ring via a pin shaft, and the plurality of support rods are arranged in a circular array, and a plurality of support rods are fixedly connected with a clamping plate near the optical fiber line, and a plurality of support rods have a side that is away from each other and is rotatably connected to the left side of the fixed ring via a pin shaft. When the rotating ring rotates, the plurality of support rods are driven to rotate. At this time, since a plurality of support rods have a side that is away from each other and is rotatably connected to the fixed ring via a pin shaft, when the rotating ring rotates, the plurality of support rods are driven to approach each other, and when the plurality of support rods are approached each other, the plurality of clamping plates are driven to approach each other, and when the plurality of clamping plates are approached each other, the optical fiber line is clamped and fixed to prevent it from falling off due to external force.

[0009] Furthermore, the number of the quick-release components is two groups, and the two groups of quick-release components are symmetrically arranged with the adapter body as the center, and the two groups of quick-release components include the same parts.

When the two optical fiber plugs are plugged in, the baffles will be close to each other under the action of force, and when the baffle moves, it will slide on the outer surface of the support rod, and the spring will be squeezed while the baffle slides. Then, the spring will be limited by the inner wall of the slide rail and will shrink and accumulate force. When the optical fiber plug is subsequently removed, the baffle will be reset under the action of the spring rebound force, and the optical fiber plug will be driven to move together while the baffle is reset, which is convenient for removing the optical fiber plug.

[0011] (2) The present invention provides an anti-drop component, specifically, rotating the knob clockwise to drive the threaded rod to rotate. When the threaded rod rotates, it drives the rotating ring to rotate. When the rotating ring rotates, it drives a plurality of clamps to approach each other. When the plurality of clamps approach each other, the optical fiber line is clamped and fixed to prevent it from falling off due to external force, thereby greatly improving the safety of stable transmission of the equipment and greatly improving the practicality of the equipment.

[0012] (3) The present invention provides a quick-release assembly, specifically, two fiber optic plugs are plugged in. At this time, the baffles are acted upon by a force to move closer to each other, and the baffles will squeeze the spring while sliding. The spring will contract and accumulate force due to the limit of the inner wall of the slide rail. When the fiber optic plug is subsequently removed, the baffle will be reset due to the rebound force of the spring.
