DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In order to solve the problems existing in the prior art, the present application provides a fiber array module. Specifically, Figures 1 to 5As shown, the optical fiber array module includes a substrate body 1, a plurality of optical fiber assemblies 2 and a fixing plate 3. The substrate body 1 includes a bottom plate 14, and a supporting portion 11 and a limiting portion 12 are protruded from the bottom plate 14. The supporting portion 11 extends from the first end of the bottom plate 14 to the second end, and the limiting portion 12 extends from the second end of the bottom plate 14 to the first end. A spacer 13 is provided between the supporting portion 11 and the limiting portion 12; a first slope 112 is provided on the end surface of the supporting portion 11 close to the second end, and a first slope 112 is provided on the end surface of the limiting portion 12 close to the first end. The second slope 122, the first slope 112, the second slope 122 and the spacer 13 form an inverted trapezoidal structure 4, the support portion 11 is provided with a plurality of first accommodating grooves 111, the limiting portion 12 is provided with a plurality of second accommodating grooves 121, wherein one second accommodating groove 121 corresponds to a plurality of first accommodating grooves 111; one end of the optical fiber assembly 2 is arranged in the first accommodating groove 111, the other end of the optical fiber assembly 2 is arranged in the second accommodating groove 121, and the stripping opening on the optical fiber 22 in the optical fiber assembly 2 is located at the inverted trapezoidal structure. Further, the fixing plate 3 is arranged at the end of the substrate body 1, and a plurality of limiting holes 31 are arranged on the fixing plate 3, and the ends of the optical fibers 22 of the optical fiber assembly 2 located in the first accommodating groove 111 are located in the limiting holes 31. Specifically, the bottom plate 14 is a flat structure, and the spacer 13 is a part of the bottom plate 14. By setting a first slope 112 on the end face of the support portion 11 and a second slope 122 on the end face of the limiting portion 12, an inverted trapezoidal structure 4 can be constructed based on the first slope 112, the second slope 122 and the spacer 13, so that the processing angle between the spacer 13 and the first slope 112 and the processing angle between the spacer 13 and the second slope 122 are both constructed as obtuse angles, which is convenient for processing. The obtuse angle reduces the incidence of edge collapse during processing and reduces the problem of easy scratching of the optical fiber 22. In addition, the optical fiber 22 is matched with the second accommodating groove 121 in the form of a component, and the installation is simple and convenient. By setting the first accommodating groove 111 and the second accommodating groove 121, the arrangement accuracy between the optical fibers 22 and the optical fibers 22 is improved, thereby improving the thermal stability of the product.

[0029] In the present technical solution, the optical fiber 22 is arranged in the form of an assembly, and the second receiving groove 121 is arranged to correspond to the plurality of first receiving grooves 111, so as to facilitate the installation of the optical fiber assembly 2. Furthermore, when the optical fiber assembly 2 is installed together, it is easy to form a misalignment, or because the distance between the two rectangular blocks is large, it is easy to cause the installation deviation of the optical fiber assembly 2. By setting the fixing plate 3, the positioning accuracy of the optical fiber assembly 2 can be improved.

[0030] In one example, the angle between the first slope 112 and the second slope 122 may be 45° to 90°. Preferably, in this example, the angle between the first slope 112 and the second slope 122 is 60°. The width of the second receiving groove 121 is between 0.9 mm and 1.2 mm.

[0031] Furthermore, the optical fiber array module further includes a cover plate 5, which is used to cover the substrate body 1, and a plurality of bosses 52 are provided on the cover plate 5. After the cover plate 5 covers the substrate body 1, the plurality of bosses 52 are matched with the plurality of second receiving grooves 121 in a one-to-one correspondence. It can be understood that by providing the cover plate 5 and providing the bosses 52 on the cover plate 5, after the cover plate 5 covers the substrate body 1, the bosses 52 can limit the optical fiber assembly 2 accommodated in the second receiving groove 121, so as to prevent the optical fiber assembly 2 from moving over a large range.

[0032] In an practicable solution, the cover plate 5 is further provided with a third receiving groove 51. After the cover plate 5 is covered with the substrate body 1, the third receiving groove 51 is matched with the first receiving groove 111 in a one-to-one manner. Exemplarily, the first receiving groove 111 and the third receiving groove 51 can both be set as a V-shaped structure. After the cover plate 5 is covered with the substrate body 1, the installed optical fiber 22 is limited in the rectangular structure formed by the first receiving groove 111 and the third receiving groove 51, which plays a certain limiting role on the optical fiber 22 and provides a certain avoidance space for the upper surface of the optical fiber 22 to avoid the cover plate 5 causing pressure loss to the optical fiber 22.

[0033] In an implementable solution, a plurality of first receiving grooves 111 are arranged on the support portion 11 at intervals along the width direction of the support portion 11 , wherein the length direction of the support portion 11 is the direction from the first end to the second end of the support portion 11 .

[0034] Furthermore, the plurality of first receiving grooves 111 are arranged at equal intervals.

[0035] In an practicable solution, the second accommodating groove 121 is a U-shaped structure with a flat bottom. It is understandable that by providing one second accommodating groove 121 corresponding to a plurality of first accommodating grooves 111, the second accommodating groove 121 can be constructed as a large U-shaped structure, that is, a relatively large flat surface is reserved for the flat bottom plate 14 of the substrate body 1, thereby improving the stability of the installation of the optical fiber assembly 2.

[0036] In an implementable solution, each group of optical fiber components 2 includes a plurality of optical fibers 22, and the optical fiber components 2 also include a packaging shell 21, which is sleeved on the optical fiber components 2, and the packaging shell 21 cooperates with the second accommodating groove 121. By providing the packaging shell 21, the optical fiber components 2 formed by the plurality of optical fibers 22 can be fixed together, which facilitates the overall assembly of the optical fiber components 2 and improves the assembly efficiency.

[0037] In one practicable solution, each set of optical fiber components 2 includes an optical fiber 22, such as Figure 6 and Figure 7As shown, the second receiving groove 121 corresponds to the first receiving groove 111. Preferably, the width of the second receiving groove 121 is between 0.2 mm and 0.5 mm.

[0038] The optical fiber array module of the present technical solution includes a substrate body 1, a plurality of optical fiber components 2 and a fixing plate 3. The substrate body 1 includes a bottom plate 14, on which a supporting portion 11 and a limiting portion 12 protrude. The supporting portion 11 extends from a first end portion to a second end portion of the bottom plate 14, and the limiting portion 12 extends from the second end portion to the first end portion of the bottom plate 14. A spacing portion 13 is provided between the supporting portion 11 and the limiting portion 12; a first slope 112 is provided on an end surface of the supporting portion 11 close to the second end portion, and a second slope 122 is provided on an end surface of the limiting portion 12 close to the first end portion. The first slope 112 and the second slope 122 are provided on the end surface of the limiting portion 12 close to the first end portion. An inverted trapezoidal structure 4 is formed between the slope 122 and the spacer 13; a plurality of first accommodating grooves 111 are provided on the support portion 11, and a plurality of second accommodating grooves 121 are provided on the limiting portion 12, wherein one second accommodating groove 121 corresponds to a plurality of first accommodating grooves 111; one end of the optical fiber assembly 2 is arranged in the first accommodating groove 111, and the other end of the optical fiber assembly 2 is arranged in the second accommodating groove 121; the fixing plate 3 is arranged at the end of the substrate body 1, and a plurality of limiting holes 31 are arranged on the fixing plate 3, and the ends of the optical fibers 22 of the optical fiber assembly 2 located in the first accommodating groove 111 are located in the limiting holes 31. The technical solution facilitates the processing of the flat portion of the spacer 13 by providing an inverted trapezoidal structure 4, reduces the incidence of edge collapse during the processing, and matches the installation of the optical fiber 22 in the form of an assembly with the second accommodating groove 121, so that the installation is simple and convenient.
