Description

Technical Field

[0001] This utility model relates to the field of optical fiber production and processing technology, specifically to a positioning fixture for MT-MINI short jumpers. Background Technology

[0002] Currently, 800G optical module products on the market often feature irregularly shaped MT-MINI jumpers due to their inherent structural design, which facilitates installation and positioning. However, there are currently no effective positioning and processing methods for these irregularly shaped MT-MINI jumpers, resulting in low processing efficiency and high defect rates. This leads to issues such as dimensional inconsistencies, poor appearance, and stress distortion during the installation process within the optical module. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning fixture for MT-MINI short jumpers, so as to solve the problem of low yield caused by the difficulty in positioning MT-MINI short jumpers in the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A positioning fixture for the MT-MINI short jumper cable, the MT-MINI short jumper cable including: a MINI connector and an MT connector, the positioning fixture including: The base has a first positioning groove and a second positioning groove arranged opposite to each other for positioning the MINI insert and the MT insert respectively.

[0009] Furthermore, the first positioning groove is provided with a second notch, which is positioned opposite to and connected to the second notch.

[0010] Furthermore, the second notch is provided with a second positioning block, which slides into the first positioning groove through the second notch to push the MINI insert against the horizontal end of the first positioning block.

[0011] Furthermore, the second positioning groove is provided with a trumpet-shaped opening.

[0012] Furthermore, the base is provided with a first strip-shaped opening, which is connected to the first positioning groove and is perpendicular to each other.

[0013] Furthermore, the base is provided with a second strip-shaped opening, which is connected to the second positioning groove and is perpendicular to each other.

[0014] Compared with the prior art, this utility model has the following advantages: the MINI insert and MT insert are positioned by the first positioning groove and the second positioning groove respectively, thereby ensuring the position and size between the two, so that the short jumper can meet the installation positioning inside the light template after processing; furthermore, the cover plate can press the MINI insert into the first positioning groove to facilitate the positioning of the MINI insert, prevent displacement, and facilitate the application and curing of glue on the MT insert, thereby greatly improving the product yield; at the same time, the cover plate adopts a double locking structure to prevent accidental opening, so as to provide reliable stability and improve positioning accuracy during processing.

[0017] The present invention will be further described in detail below through specific embodiments: In the embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the positioning fixture for the MT-MINI short jumper cable includes: a base 2, a cover plate 3, a first locking structure 4, and a second locking structure 5. The base 2 has a first positioning groove 201 and a second positioning groove 202 arranged opposite to each other for positioning the MINI plug and the MT plug, respectively. The cover plate 3 is detachably mounted on the base 2 for pressing or releasing the MINI plug located in the first positioning groove 201. The first locking structure 4 includes a locking opening 401 and a locking block 402 respectively disposed on the base 2 and the cover plate 3. The locking block 402 can move with the cover plate 3 and extend into or out of the locking opening 401. The second locking structure 5 includes a locking hole 501 and an elastic protrusion 502 respectively disposed on the locking opening 401 and the locking block 402. The elastic protrusion 502 engages with the locking hole 501 to restrict the locking block 402 from disengaging from the locking opening 401.

[0018] Specifically, in the embodiments of this utility model, such as Figure 1 As shown, the MT-MINI short patch cord 1 includes a MINI ferrule 101 and an MT ferrule 102. During processing, the MINI ferrule 101 is processed first due to its relatively weak reliability. After processing, the MT ferrule 102 is stripped of its fiber, and the optical fiber is inserted into the MT ferrule 102. Because this short patch cord is irregularly shaped, in order to ensure that its size and position after processing conform to the installation positioning inside the optical template, the short patch cord needs to be positioned at this positioning fixture before applying glue to the MT ferrule 102.

[0019] In this embodiment of the invention, the base 2 is provided with a first positioning groove 201 and a second positioning groove 202 opposite to each other along its width direction. The size and shape of the first positioning groove 201 and the second positioning groove 202 are adapted to the size and shape of the MINI insert and the MT insert, respectively, so as to facilitate the installation of the two inserts into the corresponding positioning grooves. In other embodiments, in order to improve the positioning accuracy of the inserts, corresponding positioning reference lines can also be set at the first positioning groove 201 and the second positioning groove 202. The insert end face coinciding with the positioning reference line can be used to determine that the insert is in place. Since the relative position of the two positioning grooves on the base 2 is fixed, the relative position and the resulting relative dimensions after each processing can remain consistent. Of course, if... Figure 2 As shown, the first positioning groove 201 and the second positioning groove 202, which are set opposite to each other, form a group. Multiple groups can be set at intervals along the length of the base 2 to facilitate batch positioning of multiple ferrules. MT ferrules at each of the second positioning grooves 202 can be sequentially glued. After the glue is applied to the MT ferrule and cured, the positioning of the MT twist line dimension is completed.

[0020] In this embodiment of the invention, since the operation process (glue injection) is performed on the MT insert, a cover plate 3 is provided to prevent the MINI insert from shifting, using the MINI insert as a positioning reference. This cover plate 3 can be placed on the base 2, so that the lower surface of the cover plate 3 presses and fixes the MINI insert within the first positioning groove 201, thereby limiting the shifting of the MINI insert. After processing, the cover plate 3 is removed to expose the MINI insert, which can then be removed. Additionally, as... Figure 3 As shown, in order to accommodate the batch processing of multiple sets of short jumpers, and to allow multiple MINI inserts to be fixed simultaneously on the same cover plate 3, the cover plate 3 extends along the length direction of the base 2 and can be configured as a long strip.

[0021] In this embodiment of the invention, to prevent the cover plate 3 from accidentally opening during processing, the base 2 and the cover plate 3 are locked together by a first locking structure 4 and a second locking structure 5. Specifically, the first locking structure 4 includes a locking opening 401 and a locking block 402. The locking opening 401 is formed at the base 2, and the locking block 402 is integrally formed on the cover plate 3. The locking block 402 can extend into the locking opening 401, which on the one hand can position the cover plate 3 to prevent it from shifting relative to the MINI insert, and on the other hand can use the friction between the locking block 402 and the locking opening 401 to keep the cover plate 3 at the base 2. Of course, multiple first locking structures 4 can also be provided to improve the stability of the cover plate 3. Additionally, a through hole, serving as a locking hole 501, is provided at the locking opening 401 of the base 2, and an elastic protrusion 502 is provided at the locking block 402. Thus, when the locking block 402 extends into the locking opening 401, it compresses the elastic protrusion 502 until it passes through the locking hole 501 and is released, causing the elastic protrusion 502 to engage within the locking hole 501, thereby further locking the cover plate 3 to the base 2. Pressing the elastic protrusion 502 and lifting the cover plate 3 exposes the MINI insert. Therefore, a double locking structure achieves a detachable connection between the cover plate 3 and the base 2, allowing for continuous positioning of the MINI insert during processing and preventing twisting or displacement.

[0022] This invention uses a first positioning groove 201 and a second positioning groove 202 to initially position each MINI insert, and then uses a cover plate 3 to reposition the MINI insert within the first positioning groove 201 to prevent it from shifting. Furthermore, a double locking structure can lock the cover plate 3 to prevent accidental opening that could affect the positioning of the MINI insert. Therefore, this positioning fixture is applicable to the processing and positioning of MT-MINI jumpers, ensuring uniform control over the position, size, and appearance of each jumper, preventing breakage, cracking, and other defects, improving yield and production efficiency, and ensuring that the processed product meets the requirements for installation and positioning within the optical module.

[0023] like Figure 4As shown, in one embodiment, a spring-loaded structure is provided within the locking opening 401. When the locking block 402 extends into the locking opening 401, the spring-loaded structure deforms and accumulates a spring-loaded force that drives the locking block 402 to extend out of the locking opening 401. Specifically, in order to quickly remove the cover plate 3, this embodiment provides a spring-loaded structure within the locking opening 401. This spring-loaded structure is elastic, allowing it to compress as the locking opening 401 gradually extends into it, thus accumulating a spring-loaded force that allows the locking block 402 to extend out of the locking opening 401. Therefore, when the elastic protrusion 502 is pressed and released, the spring-loaded structure can lift the locking block 402 and the cover plate 3 upwards together, causing the upper surface of the cover plate 3 to protrude from the upper surface of the base 2, facilitating quick removal of the cover plate 3. Preferably, the spring-loaded structure is a spring 6.

[0024] like Figure 5 , Figure 6 As shown, in one embodiment, a first notch 203 is provided at one end of the first positioning groove 201 facing the second positioning groove 202. The first notch 203 is connected to the first positioning groove 201 and can expose the first positioning groove 201. Specifically, in order to avoid the optical fiber, this embodiment provides a first notch 203 on the end face of the first positioning groove 201. The first notch 203 can expose the end of the first positioning groove 201 facing the second positioning groove 202, so that the optical fiber can extend unobstructed to the second positioning groove 202.

[0025] Furthermore, such as Figure 5 , Figure 6As shown, in one embodiment, the first notch 203 is provided with a first positioning block 7. The first positioning block 7 has an L-shaped structure, with its horizontal end extending through the first notch 203 into the first positioning groove 201 to guide the MINI ferrule, and its vertical end abutting against the base 2. Specifically, due to the setting of the first notch 203, one end of the first positioning groove 201 is open. In order to balance the requirements of unobstructed extension of the optical fiber and precise positioning of the MINI ferrule, this embodiment sets the first positioning block 7. The first positioning block 7 has an L-shaped structure, so that its horizontal end can extend through the first notch 203 into the first positioning groove 201, thus forming a guide surface on its end face, so that the MINI ferrule can be installed in the first positioning groove 201 along the guide surface. At the same time, the vertical end of the first positioning block 7 abuts against the base 2, so that the entire first positioning block 7 is fixed at the base 2. Of course, the height of the first positioning block 7 is lower than the height of the optical fiber, so that the MINI ferrule can be positioned without affecting the free extension of the optical fiber. Since there are multiple first positioning slots 201, multiple first positioning blocks 7 can be set, and the multiple first positioning blocks 7 can be connected in sequence. In order to fix the first positioning blocks 7 to the base 2, a mounting plate can also be set. The mounting plate is fixedly connected to the first positioning blocks 7, and multiple mounting through holes are provided on it so as to fix the mounting plate to the base 2 with screws.

[0026] like Figure 5 , Figure 6 As shown, in one embodiment, the first positioning groove 201 is provided with a second notch 204, and the first notch 203 and the second notch 204 are arranged opposite to each other and connected. Specifically, in order to facilitate the placement and removal of the MINI insert, this embodiment provides a second notch 204 on the opposite end face of the first notch 203, so that the end face of the first positioning groove 201 is open, thereby reducing the obstruction of the inner wall of the first positioning groove 201 to the placement and removal of the MINI insert.

[0027] Furthermore, such as Figure 5 , Figure 6As shown, in one embodiment, the second notch 204 is provided with a second positioning block 8. The second positioning block 8 slides into the first positioning groove 201 through the second notch 204 to push the MINI insert against the horizontal end of the first positioning block 7. Specifically, in order to improve the positioning accuracy of the MINI insert in the first positioning groove 201, it is first guided into the first positioning groove 201 by the end face of the first positioning block 7 as a guide surface. However, in order to reduce the distance between the two and thus ensure the positional accuracy of the MINI insert, this embodiment provides a second positioning block 8 at the second notch 204. The second positioning block 8 slides into the first positioning groove 201 through the second notch 204. In this way, when the second positioning block 8 gradually slides into the first positioning groove 201, it can push the MINI insert towards the end face of the first positioning block 7 until the two abut against each other, thus ensuring the uniqueness of the MINI insert's position. Similarly, multiple first positioning slots 201 can be adapted to multiple second positioning blocks 8. The multiple second positioning blocks 8 can be connected to push multiple MINI inserts at the same time so that the positions of each insert are uniform.

[0028] like Figure 5 , Figure 6 As shown, in one embodiment, the second positioning groove 202 is provided with a flared opening 205 to avoid the end face of the MT ferrule.

[0029] like Figure 5 , Figure 6 As shown, in one embodiment, the base 2 is provided with a first strip opening 206, which is connected to the first positioning groove 201 and is perpendicular to each other, so as to facilitate the placement and removal of the MINI insert; similarly, in order to facilitate the placement and removal of the MT insert, the base 2 is provided with a second strip opening 207, which is connected to the second positioning groove 202 and is perpendicular to each other.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
