Description

Technical Field

[0001] This utility model relates to the field of fiber optic array technology, specifically to a fiber optic array with double cover plates. Background Technology

[0002] An optical fiber array is an optical fiber device consisting of multiple optical fibers arranged precisely in parallel. It is typically composed of a glass V-groove, a glass cover plate, optical fibers, and fixing adhesive. With the development of silicon photonics integration technology and optical fiber sensing, the optical fibers in an optical fiber array sometimes need to be fused with another optical fiber as a transition, such as from ordinary single-mode fiber to small mode field fiber, polarization-maintaining fiber to ordinary single-mode fiber, or single-mode fiber to multimode fiber. Therefore, it is necessary to protect the fusion splice while fixing the optical fiber.

[0003] To address this, China Patent Network published a double-cover fiber optic array with application number 202020333852.3. Through the combined use of a glass V-groove, a first fiber, a second fiber, fiber fusion splices, a front cover, and a grooved rear cover, it avoids the fiber fusion splices from being easily squeezed and broken within the V-groove, resulting in higher product reliability. Furthermore, the fiber fusion splices and the second fiber are separately bonded and protected, offering advantages in miniaturization. It is applicable to various fusion-type fiber optic arrays, such as those ranging from ordinary single-mode fiber to small-mode field fiber, polarization-maintaining fiber to ordinary single-mode fiber, and single-mode fiber to multimode fiber. It only requires adding a rear cover to the existing mature manufacturing process of ordinary single-cover fiber optic arrays, resulting in minimal increase in overall manufacturing cost. By bonding the rear cover, the steps of the glass V-groove, the fiber fusion splices, and the second fiber together with adhesive, it strengthens the bonding and protection of the fiber fusion splices and the second fiber, providing sufficient protection for both, thus achieving a miniaturized and highly reliable fusion-type fiber optic array.

[0004] Although the above-mentioned application meets the user's needs to a certain extent, there are still some defects in the use process. The specific problems are as follows: since the back cover plate, the glass V-groove step, the optical fiber splice point and the second optical fiber are bonded together with glue, when the glue is not completely solidified, external impacts or collisions between the optical fiber arrays will affect the bonding effect and reduce the working efficiency of the optical fiber array processing. Based on this, this utility model designs a double-cover optical fiber array to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a double-cover fiber optic array to solve the problem mentioned in the background art that, since the back cover plate, the glass V-groove step, the fiber optic splice point and the second fiber are bonded together with adhesive, when the adhesive has not fully solidified, external impacts or collisions between the fiber optic arrays will affect the bonding effect and reduce the working efficiency of fiber optic array processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fiber optic array with double covers, including a mounting base, a rear cover plate at the top of the mounting base, and a disassembly and drying assembly fixedly mounted at the top of the mounting base, the disassembly and drying assembly including a mounting groove, a moving block, a connecting plate, an ultraviolet lamp, and a blower.

[0007] The mounting base has mounting slots on both sides for easy installation and disassembly. A moving block is slidably connected inside the mounting slot, and a connecting plate for installation is slidably connected inside the moving block. The bottom of the connecting plate is equipped with a fast-drying ultraviolet lamp, and two blowers are symmetrically fixed to the bottom of the connecting plate. This allows for rapid drying and solidification of the back cover plate, the steps of the glass V-groove, the fiber optic splice point, and the second fiber after adhesive bonding, preventing external impacts or collisions between fiber arrays from affecting the bonding effect.

[0008] The mounting base is internally fixedly equipped with a protective mounting assembly, which includes a return spring, a positioning plate, a connecting block, and a mounting block.

[0009] The rear cover plate is fixedly connected with a reset spring at equal intervals inside. One end of the reset spring is fixedly connected with a positioning plate that limits the optical fiber. The bottom end of the rear cover plate is symmetrically fixedly connected with a connecting block. The connecting block is slidably connected with an installation block inside, which can position the outer side of the optical fiber and ensure the installation effect of a single optical fiber.

[0010] Preferably, the disassembly and drying assembly further includes a limiting rod, a limiting spring, and a limiting hole;

[0011] The movable block is internally slidably connected to a limiting rod for positioning the connecting plate. A limiting spring is fixedly sleeved on the outside of the limiting rod, and limiting holes are equidistantly opened inside the connecting plate.

[0012] Preferably, the protective mounting assembly further includes a first spring and a through groove;

[0013] The connecting block is internally fixedly connected to a first spring, and the mounting base is internally provided with symmetrical through slots.

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

[0015] 1. By disassembling the drying assembly, the back cover plate, the steps of the glass V-groove, the fiber optic splice point, and the second fiber can be quickly dried and solidified after the adhesive bonding. This avoids external impacts or collisions between fiber arrays affecting the bonding effect, thus improving the working efficiency of fiber array processing. At the same time, the position of the connecting plate can be adjusted by the cooperation of the mounting slot and the moving block, and the moving block can be quickly installed and disassembled, making it convenient for staff to use.

[0016] 2. The protective installation components enable positioning of the outer side of the optical fiber, ensuring the installation effect of a single optical fiber. At the same time, by embedding the connecting block and the mounting block inside the mounting base, the back cover can still be fixed even if the adhesive comes off after long-term use of the optical fiber array, making it convenient to add adhesive later and improving the performance of the back cover.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 This utility model provides a technical solution: a fiber optic array with double covers, including a mounting base 1, a rear cover 4 at the top of the mounting base 1, both the rear cover 4 and the front cover 4 are made of transparent material to facilitate the transmission of ultraviolet light through the rear cover 4 and the front cover 4, and a disassembly and drying assembly 2 is fixedly installed at the top of the mounting base 1, the disassembly and drying assembly 2 including a mounting groove 201, a moving block 202, a connecting plate 203, an ultraviolet lamp 204 and a blower 205;

[0029] Mounting base 1 has mounting slots 201 on both sides inside for easy installation and disassembly. A moving block 202 is slidably connected inside the mounting slot 201. A connecting plate 203 for installation is slidably connected inside the moving block 202. A fast-drying ultraviolet lamp 204 is provided at the bottom of the connecting plate 203. The ultraviolet lamp 204 is electrically connected to the output terminal of an external power supply. Two blowers 205 are symmetrically fixed at the bottom of the connecting plate 203. One end of the blower 205 is connected to an external air pump to facilitate blowing air onto the top of the mounting base 1 and accelerate the curing speed of the adhesive.

[0030] The protective mounting assembly 3 is fixedly installed inside the mounting base 1. The protective mounting assembly 3 includes a return spring 301, a positioning plate 302, a connecting block 303, and a mounting block 305.

[0031] A reset spring 301 is fixedly connected at equal intervals inside the rear cover plate 4. One end of the reset spring 301 is fixedly connected to a positioning plate 302 for limiting the optical fiber. A connecting block 303 is fixedly connected symmetrically to the bottom end of the rear cover plate 4. An installation block 305 is slidably connected inside the connecting block 303.

[0032] The disassembly drying assembly 2 also includes a limiting rod 206, a limiting spring 207, and a limiting hole 208;

[0033] The movable block 202 has a sliding connection inside which a limiting rod 206 is used to position the connecting plate 203. A fixing plate is sleeved on the outside of the limiting rod 206 to prevent the limiting rod 206 from sliding out and to facilitate limiting the limiting rod 206. A limiting spring 207 is fixedly sleeved on the outside of the limiting rod 206. Limiting holes 208 are equidistantly opened inside the connecting plate 203.

[0034] The mounting base 1, front cover plate, and rear cover plate 4 are ultrasonically cleaned and dried. A small section of the coating is stripped from the front end of a longer first optical fiber. A small section of the coating is also stripped from the front end of a second optical fiber of the required length. The first and second optical fibers are then fused together using a fiber optic fusion splicer. The mounting base 1 is placed in the assembly fixture and secured. The fused first and second optical fibers are then placed into the mounting base 1, and the positions of the fibers are adjusted to ensure that the first optical fiber is embedded in the V-groove of the mounting base 1, with the fusion splice point at the front end of the step. The tail of the second optical fiber is then temporarily secured to the clamp using single-sided tape. The front cover plate is placed above the mounting base 1, and the first optical fiber is pressed down until it is fully inserted. Insert the adhesive A into the V-groove of the mounting base 1 and fix it at the beveled part of the small step of the mounting base 1. Embed the moving block 202 into the mounting groove 201 to complete the installation of the moving block 202 and the connecting plate 203. Pushing the moving block 202 can adjust the drying position of the ultraviolet lamp 204 and the blower 205. Pulling the limiting rod 206 moves the limiting rod 206 out of the limiting hole 208. Pulling the connecting plate 203 can adjust the working height of the ultraviolet lamp 204 and the blower 205. Releasing the limiting rod 206 allows the connecting plate 203 to be positioned by the rebound force of the limiting spring 207, which speeds up the drying and solidification of the adhesive and improves the working efficiency of fiber array processing.

[0035] The protective mounting assembly 3 also includes a first spring 304 and a through groove 306;

[0036] The connecting block 303 has a first spring 304 fixedly connected inside. One end of the first spring 304 is fixedly connected to the mounting block 305, which facilitates the positioning of the outer side of the optical fiber and ensures the installation effect of a single optical fiber. The mounting base 1 has through slots 306 symmetrically opened inside.

[0037] Place the inverted back cover plate 4 above the step and press it down until the second optical fiber and the optical fiber splice point are completely inserted into the groove. Apply fixing glue B at the step of the mounting base 1. When installing the back cover plate 4, push the mounting block 305 into the inside of the connecting block 303 and embed the two connecting blocks 303 into the inside of the mounting base 1. After the connecting blocks 303 are inside the mounting base 1, the first spring 304 resets and drives the mounting block 305 into the through groove 306 to fix the back cover plate 4 and the mounting base 1. This can ensure the fixing effect of the back cover plate 4 even when the glue comes off after long-term use of the optical fiber array, and facilitates the addition of glue later. At the same time, after the back cover plate 4 is installed, the reset spring 301 drives the positioning plate 302 to limit the outside of the optical fiber to ensure the installation effect of a single optical fiber.
