Pluggable collimation products are mainly used in multi-channel laser products to converge the collimated light of multiple channels into the optical fiber for transmission to achieve optical signal transmission; and at the receiving end, the signal in the optical fiber is converged to the optoelectronic conversion device to achieve optical signal reception.

[0003] Based on the above, the inventors have found the following problems: the existing pluggable optical fiber collimator is usually assembled by an optical fiber socket and a kit equipped with a lens, and the optical fiber socket and the kit are basically assembled by threads and thread grooves provided on the surface. When the optical fiber socket needs to be replaced, due to the small size of the pluggable optical fiber collimator, it is necessary to use tools to disassemble it, which is very inconvenient; and in order to prevent the gas in the chamber between the optical fiber socket and the kit from expanding due to environmental changes and affecting the position of the lens, the existing pluggable optical fiber collimator usually has air holes on the kit. As time goes by, dust will enter the chamber, thereby affecting the collimation effect of the optical fiber collimator.

[0030] Among them, the sliding groove 5 matches the sliding block 8. Through the cooperation of the sliding groove 5 and the sliding block 8, when the optical fiber socket 3 and the kit 1 are matched and installed, the engaging groove 11 and the engaging hole 10 correspond to each other; one end of the sliding block 8 is arranged at the end of the kit 1 away from the lens 4, and the other end of the sliding block 8 is connected to the baffle 15. Through the cooperation of the baffle 15, the sliding block 8, the sliding groove 5 and the engaging assembly, the relative positions of the optical fiber socket 3 and the kit 1 can be fixed when they are engaged; the annular sealing ring 6 matches the sealing ring groove 12. Through the cooperation of the annular sealing ring 6 and the sealing ring groove 12, dust can be prevented from entering the gap between the optical fiber socket 3 and the kit 1 to affect the collimation effect of the collimator; the engaging hole 10 matches the engaging groove 11.

[0031] The clamping assembly includes a clamping block 201, a limiting column 202 is provided at the bottom of the clamping block 201, and a spring 203 is provided at the bottom of the limiting column 202, and one end of the spring 203 is fixedly connected to the bottom end of the clamping groove 11, and the other end of the spring 203 is fixedly connected to the bottom end of the limiting column 202, and a pair of limiting grooves 204 are opened on the side wall of the clamping groove 11, and the two ends of the limiting column 202 are located in the limiting grooves 204, through the limiting grooves 204 and the limiting column 2 The design of 02 can make the movement trajectory of the locking block 201 maintain on a trajectory perpendicular to the axis of the optical fiber socket 3 under the action of the spring 203 and the external force, thereby avoiding reducing the locking effect of the locking assembly. Through the design of the spring 203, the limiting column 202 and the locking block 201, the locking block 201 can flexibly extend and retract in the locking groove 11 with the compression and rebound of the spring 203, thereby achieving the effect of the locking block 201 flexibly engaging and disengaging in the locking hole 10.

[0032] Among them, the rubber sealing plate 13 is movably connected to the two sides of the engaging hole 10 by bolts. The rubber sealing plate 13 has high elasticity and sealing performance. The rubber sealing plate 13 is flexibly installed on the two sides of the engaging hole 10, so that the rubber sealing plate 13 can be flexibly replaced; and when external force is applied through the upper end surface of the rubber sealing plate 13, the engaging block 201 can be easily pushed out of the engaging hole 10, thereby realizing easy disassembly of the optical fiber socket 3 and the kit 1. Due to the high elasticity of the rubber sealing plate 13, when the force pressing the rubber sealing plate 13 is released, the rubber sealing plate 13 can quickly restore to its original state, so that the engaging assembly can be engaged in the engaging hole 10 again.

[0033] The breathable dustproof pad 701 is movably installed in the air hole 7.

[0036] The specific usage and function of this embodiment are as follows:

[0037] When using the device, first check the integrity of the device. When the optical fiber needs to be aligned, insert the optical fiber socket 3 into the kit 1. At this time, through the cooperation of the sliding groove 5 and the sliding block 8, the relative positions of the optical fiber socket 3 and the kit 1 are installed according to the specified position during the insertion of the optical fiber socket 3 into the kit 1. When the optical fiber socket 3 is gradually inserted into the kit 1, the lower side of the upper end surface of the clamping block 201 first contacts the outer wall of the kit 1. Due to the inclined design of the upper end surface of the clamping block 201, the clamping block 201 is squeezed by the side wall of the kit 1. The engaging block 201 moves downward in the engaging groove 11 and compresses the spring 203. When the engaging groove 11 reaches the vertical position of the engaging hole 10, the engaging block 201 moves into the engaging hole 10 under the action of the spring 203 rebounding, thereby achieving the engaging effect between the optical fiber socket 3 and the kit 1. When the optical fiber socket 3 needs to be disassembled, the rubber sealing plate 13 is pressed to disengage the engaging block 201 from the engaging hole 10, and then the optical fiber socket 3 and the kit 1 are pulled apart along the axial direction, thereby achieving easy disassembly and installation of the optical fiber socket 3 and the kit 1.
