Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] To address the problems existing in the prior art, this application provides a fiber optic array assembly, specifically, as follows: Figure 1 as well as Figure 8 As shown, the substrate body 1 includes a protrusion 11 and a flat portion 12. The protrusion 11 and the flat portion 12 are connected by a first ramp 13, and the first ramp 13 and the flat portion 12 are connected at an obtuse angle. It can be understood that by providing the first ramp 13 between the protrusion 11 and the flat portion 12, and setting the first ramp 13 and the flat portion 12 at an obtuse angle, the processing of the substrate body 1 can be facilitated, and the occurrence rate of edge chipping problems at the connection between the protrusion 11 and the flat portion 12 during processing can be reduced. Furthermore, the protrusion 11 is provided with a first reinforcing groove 111 and a plurality of first receiving grooves 112 arranged at intervals. The first reinforcing groove 111 extends through the plurality of first receiving grooves 112 along the arrangement direction of the plurality of first receiving grooves 112. There is at least one first reinforcing groove 111, and the bottom of two adjacent first receiving grooves 112 are spaced apart by a first target distance. Specifically, by setting reinforcing grooves that penetrate and run parallel to the first receiving grooves 112, the reinforcing grooves can intersect with each of the first receiving grooves 112. The intersection points are used as installation reference points for the optical fiber 3, thereby improving the positioning accuracy, consistency, and reliability of the optical fiber 3 during installation. Further, in one example, the first target distance can be less than the width of the first receiving groove 112, or it can be equal to or greater than the width of the first receiving groove 112. The specific distance value can be set according to requirements and is not specifically limited here. In a preferred embodiment, the substrate body 1 can be made of BF33 high borosilicate glass, which has good mechanical properties, stability, and corrosion resistance, and can be used stably for a long time in harsh environments such as high temperature, high pressure, and acids and alkalis.

[0033] For further information, please refer to [link / reference]. Figure 1 The fiber array assembly also includes a cover plate 2, which is used to cover the substrate body 1. The reliability of the fiber 3 after installation is improved by pressing the cover plate 2.

[0034] In a feasible solution, such as Figures 1 to 7As shown, the first reinforcing groove 111 is a single strip. Specifically, in this example, the first reinforcing groove 111 is constructed as a V-shaped structure, and the first receiving groove 112 is constructed as a U-shaped structure. The U-shaped first receiving groove 112 includes a first receiving portion 1121 and a second receiving portion 1122. The first receiving portion 1121 is constructed as a second slope, with the end of the second slope away from the second receiving portion 1122 being lower than the end of the second slope near the second receiving portion 1122. The first reinforcing groove 111 extends through the multiple first receiving portions 1121 corresponding to the multiple first receiving grooves 112 along the arrangement direction of the multiple first receiving grooves 112. By setting the first receiving groove 112 with a sloped U-shaped structure, the edge chipping problem that may occur during vertical groove processing is avoided.

[0035] Furthermore, a third slope 14 is also provided on the substrate body 1. The third slope 14 is located on the end face of the protrusion 11 away from the first slope 13, and the inclination direction of the third slope 14 is consistent with that of the first slope 13. Specifically, in actual use, the front end of the fiber optic array 3 needs to have a certain angle, ranging from 4° to 60°. Therefore, the front end of the substrate body 1 needs to be ground. However, grinding a conventionally structured substrate requires a long time and a large amount of grinding. In this technical solution, by setting the third slope 14, a certain angle is removed from the substrate body 1 during the initial fabrication process, which can effectively reduce the amount of grinding and the grinding time.

[0036] In another feasible solution, the first reinforcing groove 111 is a single strip. Specifically, in this example, both the first reinforcing groove 111 and the first receiving groove 112 are constructed as V-shaped structures. By intersecting the V-shaped grooves, the installation positioning point can be determined more accurately, thereby improving the installation accuracy of the optical fiber 3.

[0037] In another feasible solution, such as Figures 8 to 12 As shown, there are multiple first reinforcing grooves 111, each with a V-shaped structure. These grooves are spaced apart along the length of the first receiving groove 112, with a second target distance separating adjacent grooves. The first receiving groove 112 also has a V-shaped structure. The multiple reinforcing grooves 111 and the multiple receiving grooves 112 correspond to form multiple installation positioning points, further improving the installation stability of the optical fiber 3 and enhancing the consistency of the multiple optical fibers 3 after installation. The second target distance can be set according to requirements and is not specifically limited here.

[0038] In one example, the opening angle of the V-groove is configured to be 60° to 120°. By setting the opening angle to 60° to 120°, perpendicular machining of the groove is avoided, improving the machining convenience of the V-groove and reducing the occurrence of edge chipping during groove machining. Furthermore, the groove depth of the V-groove is 0.1mm to 0.4mm, which can avoid the problem of excessive removal of the body due to excessive groove depth, resulting in a relatively weak body part that is prone to breakage.

[0039] For further information, please refer to [link / reference]. Figure 8 In one example, the cover plate 2 has a number of second reinforcing grooves 21 corresponding to the number of first reinforcing grooves 111. The second reinforcing grooves 21 are configured such that after the cover plate 2 is closed on the substrate body 1, the second reinforcing grooves 21 correspond to and engage with the first reinforcing grooves 111. By providing the second reinforcing grooves 21 on the cover plate 2, the reinforcing grooves can act as reinforcing ribs, improving the overall strength of the cover plate 2. Furthermore, the number of second reinforcing grooves 21 is set according to the number of first reinforcing grooves 111, and the second reinforcing grooves 21 correspond to and engage with the first reinforcing grooves 111 after the cover plate 2 is closed on the substrate body 1, which can improve the alignment and installation accuracy of the cover plate 2 and the substrate body 1. Furthermore, the fiber array assembly also includes an optical fiber 3, which is accommodated in the first receiving groove 112. Specifically, after the optical fiber 3 is installed into the receiving groove, the stripped end of the optical fiber 3 is located in the first reinforcing groove 111. By setting the first reinforcing groove 111, the positioning of the stripping opening can be made more convenient, improving the installation accuracy of the optical fiber 3 and the positioning consistency after multiple optical fibers 3 are installed. In one example, during the installation of the optical fiber 3 on the substrate body 1, adhesive can be applied to the first receiving groove 112, and then a flat small glass plate can be used to press the optical fiber 3 into the first receiving groove 112. After curing, protective adhesive can be applied to the platform area behind the first receiving groove 112.

[0040] Furthermore, in this example, please refer to... Figure 10 and Figure 12 As shown, the protrusion 11 also includes a first blocking part 113 and a second blocking part 114 symmetrically arranged. A first receiving groove 112 is disposed between the first blocking part 113 and the second blocking part 114. The first blocking part 113 and the first receiving groove 112 are connected by a first step 115, and the second blocking part 114 and the first receiving groove 112 are connected by a second step 116.

[0041] Specifically, the fiber optic array assembly of this utility model includes a substrate body 1, a cover plate 2, and an optical fiber 3. The substrate body 1 includes a protrusion 11 and a flat portion 12, which are connected by a first ramp 13. The first ramp 13 and the flat portion 12 are connected at an obtuse angle. The protrusion 11 has a first reinforcing groove 111 and a plurality of first receiving grooves 112 arranged at intervals. The first reinforcing groove 111 extends through the plurality of first receiving grooves 112 along the arrangement direction of the plurality of first receiving grooves 112. There is at least one first reinforcing groove 111, and the bottom of two adjacent first receiving grooves 112 are spaced apart by a first target distance. The cover plate 2 is used to cover the substrate body 1. The cover plate 2 has a number of second reinforcing grooves 21 corresponding to the number of first reinforcing grooves 111. The second reinforcing grooves 21 are configured to cooperate with the first reinforcing grooves 111 after the cover plate 2 is covered on the substrate body 1. The optical fiber 3 is used to be accommodated in the first receiving grooves 112. This application can provide a reference line for the installation of fiber optic cable 3, improving the installation accuracy, consistency and reliability of fiber optic cable 3.
