Description

Technical Field

[0001] The utility model relates to the field of optical communication devices, in particular to an aspherical tube cap of an optical communication device. Background Art

[0002] Optical communication devices refer to various optical equipment and components used in optical communication systems to transmit, regulate and control the transmission of optical signals. Optical communication devices play a vital role in the field of modern communications. They can achieve high-speed, high-bandwidth and long-distance optical signal transmission.

[0003] A pipe cap with patent application number CN202222836449.4 relates to the technical field of optical communication equipment. It includes a pipe cap body, the interior of the pipe cap body is a convex-shaped cavity; the pipe cap body is composed of a pipe cap body and a fixing frame at one end of the pipe cap body. The convex-shaped cavity inside the pipe cap body is used to install lenses and other optical devices; specifically, the lens is installed in the cavity inside the pipe cap body, that is, the upper half of the convex-shaped cavity. Compared with the installation method in which the lens only partially enters the pipe cap in the traditional optical communication pipe cap, the pipe cap in this scheme can completely install the lens, thereby effectively avoiding the problem of position displacement of the lens due to insufficient connection during the actual transportation, movement, packaging, etc. of the pipe cap, or being easily contaminated due to exposure, thereby ensuring the performance of the pipe cap and the normal operation of the optoelectronic device. Although the above-mentioned pipe cap can completely install the lens when in use, the lens does not have any limit and protective components after being installed in the pipe cap, so it is inevitable that position displacement will occur during actual transportation.

[0004] In optical communication devices, the lens is a crucial component. During the installation process of the lens, the staff needs to first install the lens in the tube cap. However, the existing methods of installing the lens into the tube cap are relatively simple. The lens lacks limit and protection components in the tube cap. Therefore, position deviation is inevitable in actual transportation, which affects the use of the lens.

[0005] Therefore, it is necessary to provide a new aspheric tube cap for optical communication devices to solve the above technical problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The aspheric tube cap of the optical communication device first inserts the lens body into the tube cap body, then the bottom of the lens body contacts the inclined surface of the clamping block, at this time the clamping block will tilt toward the inner cavity of the groove, and then the spring will also shrink, when the lens body moves down to the top of the supporting pad, the spring will drive the clamping block to rebound, at this time the bottom of the clamping block will be clamped with the top of the lens body to limit the lens body, and then the staff will install the protective ring on the top of the lens body, which can seal the gap between the lens body and the inner wall of the tube cap body, and at the same time can also protect the lens body;

[0016] The invention solves the problem that the existing methods of installing the lens into the tube cap are relatively simple, the lens lacks limit and protection components in the tube cap, so position deviation is inevitable in actual transportation, thereby affecting the use of the lens.

[0024] In the specific implementation process, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the front and rear sides of the lens body 7 are fixedly connected with plug blocks 9, the surface of the plug block 9 is movably connected to the inner cavity of the slot 10, the bottom of the surface of the cap body 4 is provided with a connection pad 3, the material of the connection pad 3 is rubber, the bottom of the connection pad 3 is in contact with the optical transmitter socket 1, the bottom of the cap body 4 is fixedly connected with a connection block 6, the surface of the connection block 6 is movably connected to the inner cavity of the limiting groove 5, the bottom of the support pad 11 is fixedly connected with a support block 12, and the side of the support block 12 close to the inner wall of the cap body 4 is in contact with the inner wall of the cap body 4. The bottom of the inner cavity of the groove 14 is movably connected with a block 15 through a rotating shaft, the top of the block 15 is provided with an inclined surface, the side of the block 15 close to the inner wall of the groove 14 is fixedly connected with a spring 16, the side of the spring 16 close to the inner wall of the groove 14 is fixedly connected to the inner wall of the groove 14, the number of the blocks 15 is six, the bottoms of the six blocks 15 are clamped with the lens body 7, the top of the lens body 7 is provided with a protective ring 8, the surface of the protective ring 8 is in contact with the inner wall of the tube cap body 4, and the material of the protective ring 8 is silicone.

As the lens body 7 continues to move downward, the bottom of the lens body 7 will contact the inclined surface of the block 15, and then the block 15 will be squeezed by the inclined surface and tilted toward the inner cavity of the groove 14, and then the spring 16 will also contract. When the lens body 7 moves down to the top of the supporting pad 11, the spring 16 will drive the block 15 rebounds, and at this time the bottom of the clamping block 15 will be clamped with the upper part of the lens body 7 to limit the lens body 7. Then the staff will install the protective ring 8 on the upper part of the lens body 7, which can seal the gap between the lens body 7 and the inner wall of the tube cap body 4, and at the same time protect the lens body 7, thereby solving the problem that the existing method of installing the lens into the tube cap is relatively simple, and the lens lacks limiting and protective components in the tube cap, so it is inevitable that position deviation will occur in actual transportation, thereby affecting the use of the lens.
