Description

Technical Field

[0001] The invention relates to the technical field of optical fiber amplifiers, and in particular to an optical fiber amplifier with a quick plug-in structure. Background Art

[0002] A fiber amplifier is a device used to increase the strength of optical signals transmitted through optical fibers. It plays a vital role in long-distance optical communication systems. As optical signals attenuate when propagating in optical fibers, fiber amplifiers are needed to compensate for this lost energy in order to ensure that the signals can be transmitted losslessly over longer distances.

[0003] In modern communication networks, fiber amplifiers play a vital role, especially in long-distance, high-capacity optical communication systems. Fiber amplifiers can compensate for the attenuation of signals during transmission, ensuring that data can be transmitted losslessly over longer distances. However, traditional fiber amplifier designs often face challenges, including operational complexity during installation and maintenance, connection reliability, and sensitivity to environmental changes.

[0004] With existing fiber optic amplifiers, when it is necessary to insert an optical fiber, an operator is usually required to press a button on it to control the clamping mechanism in the insertion hole to relax, open the insertion hole, insert the optical fiber, and then release the button so that the clamping mechanism clamps the optical fiber. This is time-consuming and labor-intensive when performing rapid detection, and is likely to affect the operator's work efficiency. For example, Chinese patent application CN201911280578.6 discloses a fiber optic amplifier, comprising an outer shell, a card slot board inserted and fixed in the outer shell, and a circuit board fixed on the card slot board, wherein the card slot board is provided with a transmitting tube for emitting an optical signal and a receiving tube for receiving an optical signal. The optical fiber is also clamped and relaxed by setting a press-type clamping mechanism, which is more troublesome when plugging and unplugging the optical fiber.

[0005] Therefore, there is a need for an optical fiber amplifier with a quick plug-in / pull-out structure to solve the above problems. Summary of the invention

[0006] In order to solve the above problem, that is, to solve the problem that the existing optical fiber amplifier is troublesome when plugging and unplugging optical fiber, which is time-consuming and labor-intensive and affects work efficiency, the present invention provides an optical fiber amplifier with a quick plug-in structure.

[0007] A fiber optic amplifier with a quick plug-in structure comprises an amplifier, the amplifier comprising a shell, two insertion holes are provided at both ends of the shell, optical fiber connectors are plugged into the two insertion holes, two docking rods are provided on the optical fiber connector, a docking mechanism is provided in the shell, the docking mechanism comprises two annular air bags arranged up and down, the two annular air bags are connected by a connecting pipe, the two annular air bags are respectively coaxial with the two insertion holes, one of the annular air bags is connected to an air source component, the air source component supplies air to the annular air bag, the air source component comprises a cylinder, the cylinder is connected to the annular air bag, a push plate is slidably provided in the cylinder, a push rod is fixedly connected to the push plate, a first spring is connected between the push plate and the inner wall of the cylinder, the push rod extends out of the shell, an extension section of the push rod is fixedly connected to an abutment frame, the abutment frame can abut against the optical fiber connector, and a clamping component is provided on the push plate.

[0008] Specifically, when in use, when the optical fiber is docked with the optical fiber amplifier, the optical fiber connector on the optical fiber is inserted into the insertion hole, that is, the two docking rods on the optical fiber connector are inserted into the two insertion holes. During the insertion of the optical fiber connector, the optical fiber connector abuts against the abutment frame, and the optical fiber connector drives the abutment frame to move in the direction close to the shell, and at the same time the abutment frame drives the push rod to move, and the push rod drives the push plate to move, and the push plate stretches the first spring, and at the same time the push plate presses the gas in the cylinder into the annular airbag, so that the two annular airbags expand, and the two annular airbags clamp the two docking rods, and at the same time the clamping piece on the push plate clamps to fix the push plate, so that the two annular airbags keep clamping the docking rods, thereby realizing the connection between the optical fiber and the optical fiber amplifier; when the optical fiber needs to be pulled out from the optical fiber amplifier, the clamping piece is unlocked, and the clamping piece unlocks the push plate, and the push plate is reset under the action of the first spring, and at the same time the push plate drives the push rod and the abutment frame to move in the direction away from the shell, and the abutment frame drives the optical fiber connector to move in the direction away from the shell, so that the two docking rods are pulled out of the insertion hole, disconnecting the optical fiber from the optical fiber amplifier.

[0009] By setting the air source part, when the optical fiber connector is inserted into the two insertion holes, the gas in the cylinder can be pressed into the annular airbag, so that the two annular airbags expand and clamp the two docking rods. By setting the clamping part, the position of the push plate is maintained, so that the annular airbags maintain the clamping of the docking rods, and the connection between the optical fiber and the optical fiber amplifier is realized. The operation is simple. Compared with the existing equipment, only the plug-in action is required, and no unnecessary actions are required, which improves the work efficiency of the operator.

[0041] Specifically, when the optical fiber is connected to the optical fiber amplifier, the optical fiber connector 13 on the optical fiber is inserted into the insertion hole 12, that is, the two connecting rods 14 on the optical fiber connector 13 are inserted into the two insertion holes 12. During the insertion of the optical fiber connector 13, the optical fiber connector 13 is in contact with the abutment frame 235, and the optical fiber connector 13 drives the abutment frame 235 to move toward the direction close to the housing 11. At the same time, the abutment frame 235 drives the push rod 233 to move, and the push rod 233 drives the push plate 232 to move. The push plate 232 stretches the first spring 234. At the same time, the push plate 232 presses the gas in the cylinder 231 into the annular airbag 21, so that the two annular airbags 21 expand, and the two annular airbags 21 are connected to the two pairs of The connecting rod 14 is clamped, and the clamping piece 24 on the push plate 232 is clamped to fix the push plate 232, so that the two annular air bags 21 keep clamping the connecting rod 14, thereby realizing the connection between the optical fiber and the optical fiber amplifier; when the optical fiber needs to be pulled out from the optical fiber amplifier, the clamping piece 24 is unlocked, and the clamping piece 24 unlocks the push plate 232, and the push plate 232 is reset under the action of the first spring 234, and at the same time, the push plate 232 drives the push rod 233 and the abutment frame 235 to move away from the shell 11, and the abutment frame 235 drives the optical fiber connector 13 to move away from the shell 11, so that the two connecting rods 14 are pulled out of the insertion hole 12, and the connection between the optical fiber and the optical fiber amplifier is disconnected.

[0042] By setting the air source part 23, when the optical fiber connector 13 is inserted into the two insertion holes 12, the gas in the cylinder 231 can be pressed into the annular airbag 21, so that the two annular airbags 21 expand and clamp the two docking rods 14.

At the same time, the gas in the lower annular airbag 21 enters the upper annular airbag 21 through the connecting tube 22, so that the upper annular airbag 21 expands. The two annular airbags 21 expand to clamp the two docking rods 14; when the optical fiber is disconnected from the optical fiber amplifier, that is, after unlocking the clamping piece 24, the push plate 232 is reset under the action of the first spring 234, and the gas in the annular airbag 21 flows back to the cylinder 231 through the air pipe 236, and the annular airbag 21 contracts to release the two docking rods 14.
