Description

Technical Field

[0001] The utility model relates to the technical field of optical modules, and in particular to an MPO buckle-MT docking device and an optical module. Background Art

[0002] The traditional optical module includes: an upper structure, a lower structure, an MPO buckle and an MT ferrule assembly. The upper structure and the lower structure both have an MPO buckle mounting cavity and an MT mounting cavity. The upper structure and the lower structure are fixedly connected by screws, and the MPO buckle and the MT ferrule assembly are respectively located in the MPO buckle mounting cavity and the MT mounting cavity. The MPO buckle and the MT ferrule assembly are separate and rely on the cooperation and compression of the upper structure and the lower structure. The MPO buckle is then plugged into the MPO plug to achieve the coupling and docking of the MPO plug and the MT ferrule assembly. The technical disadvantages are as follows: after the MT ferrule assembly is compressed, the optical axis plane of the MT ferrule assembly is misaligned with the optical axis plane of the MPO buckle, which causes the guide pin on the MT ferrule assembly to be inaccurately docked with the hole on the MPO plug when the MPO plug is inserted, resulting in abnormal plug-in optical power in the optical module and poor difference and consistency. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an MPO buckle-MT docking device and an optical module to overcome the deficiencies in the above-mentioned prior art.

[0004] The utility model solves the above-mentioned technical problem with a technical solution as follows: an MPO buckle-MT docking device, comprising: an MPO buckle and an MT ferrule assembly, the MPO buckle comprising: a plug-in portion for plugging and mating with an MPO plug, two relatively distributed cantilevers are fixed at one end of the plug-in portion away from the MPO plug, and a reverse buckle is fixed on each of the two side surfaces of each cantilever, the MT ferrule assembly is plugged between the two cantilevers and clamped by the two cantilevers, the two reverse buckles on each cantilever are clamped on the outer side surface of the card in the MT ferrule assembly, the inner side surface of each cantilever has a slope that is close to the convex rib on the optical fiber end of the MT ferrule assembly, the two slopes of the two cantilevers are distributed in an eight-shaped shape and the bundle end faces the plug-in portion, and a limiting portion that is close to the side surface of the MT ferrule assembly is arranged on both sides of each cantilever along its length direction, the limiting portion is fixedly connected to the plug-in portion, and the optical axis plane of the MT ferrule assembly coincides with the optical axis plane of the MPO buckle.

[0005] The beneficial effects of the utility model are:

[0006] The MPO buckle is designed to be elastic. By inserting the MT ferrule assembly onto the elastic MPO buckle and ensuring that the optical axis plane of the MT ferrule assembly coincides with the optical axis plane of the MPO buckle, when the MPO plug is further inserted and mated with the MPO buckle, the MT ferrule assembly can be accurately coupled with the MPO plug without relying on any other auxiliary structures (i.e., without relying on the pressing action of the upper and lower structural parts to achieve coupling), effectively improving the docking efficiency between the MPO plug and the MT ferrule assembly, enhancing the optical power, so as to solve the problems of abnormal and different insertion and extraction optical powers and poor consistency. Moreover, this structure can be used as a separate docking test device for the MPO plug and the MT ferrule assembly to optimize the test link;

[0007] Only two cantilevers are designed and each cantilever has two reverse buckles, which is beneficial to ensure the consistency of the two reverse buckles on each cantilever, can better clamp the MT ferrule assembly, and is more convenient for insertion and extraction;

[0008] The ramp can help absorb tolerances and clamp the MT ferrule assembly and hold it in a fixed position, thus ensuring that the optical axis plane of the MT ferrule assembly coincides with the optical axis plane of the MPO buckle after the MT ferrule assembly is inserted into the MPO buckle, so that the optical axis plane of the MT ferrule assembly is consistent with the optical axis plane of the MPO plug inserted into the MPO buckle.

[0009] Based on the above technical solutions, the present utility model can be further improved as follows.

[0010] Further, the inner side surface of each cantilever includes: a first horizontal section, a ramp, and a second horizontal section connected in sequence, and the first horizontal section is close to the reverse buckle.

[0011] The beneficial effect of adopting the above is that: the inner side surface of the cantilever can adapt to the shape of the MT ferrule assembly, thus stably clamping the MT ferrule assembly to prevent the MT ferrule assembly from loosening, and at the same time facilitating the insertion and extraction of the MT ferrule assembly.

[0012] Further, a guiding angle is provided on the side surface of each reverse buckle facing away from the insertion part.

[0013] The beneficial effect of adopting the above is that: it is convenient for the MT ferrule assembly to be inserted between the two cantilevers.

[0014] Further, the MPO buckle is integrally formed by an injection molding process.

[0015] Based on the above technical solutions, the present utility model further provides an optical module, including: an upper structural part, a lower structural part, and an MPO buckle - MT docking device. The upper structural part and the lower structural part are fixedly connected by screws, and the MPO buckle is inserted and mated with the MT ferrule assembly and clamped by the upper structural part and the lower structural part.

[0016] A further beneficial effect of the above is that accurate coupling between the MT ferrule assembly and the MPO plug can be achieved without relying on the compression effect of the upper structure and the lower structure.

[0017] Furthermore, the MPO buckle and the MT ferrule assembly are distributed laterally between the upper structure and the lower structure.

[0018] Furthermore, the MPO buckle and the MT ferrule assembly are vertically distributed between the upper structure and the lower structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0029] Example 1

[0030] likeFigure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, an MPO buckle-MT docking device includes: an MPO buckle 1 and an MT ferrule assembly 2, the MT ferrule assembly 2 is plugged and matched with the MPO buckle 1, and the optical axis plane of the MT ferrule assembly 2 coincides with the optical axis plane of the MPO buckle 1, and the MPO buckle 1 is then plugged with the MPO plug 3, so that the MT ferrule assembly 2 and the MPO plug 3 are accurately docked and coupled;

[0031] The MPO buckle 1 includes: a plug-in portion 110, the plug-in portion 110 has an inner cavity, the plug-in portion 110 is plugged and matched with the MPO plug 3, the matching of the plug-in portion 110 and the MPO plug 3 belongs to the existing conventional technology, and the matching of the two is not described in detail here. The end of the plug-in portion 110 away from the MPO plug 3 is fixed with two relatively distributed cantilevers 120, for example, Figure 1 , Figure 2 As shown, the two cantilevers 120 are distributed up and down, and this is only an exemplary description based on the angles shown in the drawings;

[0032] There is a certain gap between the two cantilevers 120, and each cantilever 120 is fixed with a buckle 130 on both sides. The MT ferrule assembly 2 is plugged between the two cantilevers 120 and clamped by the two cantilevers 120, and the two buckles 130 on each cantilever 120 are clamped on the outer side of the card 210 in the MT ferrule assembly 2 to prevent the MT ferrule assembly 2 from not being plugged in place, resulting in insufficient matching length between the guide pin of the MT ferrule assembly 2 and the hole on the MPO plug 3. Only two cantilevers 120 are designed and each cantilever 120 has two buckles 130, which is conducive to ensuring the consistency of the two buckles 130 on each cantilever 120, and can better clamp the MT ferrule. The core assembly 2 is more convenient to plug and unplug. In addition, the inner side of each cantilever 120 has a slope 121 that is close to the convex rib 220 on the optical fiber end of the MT ferrule assembly 2. The slope 121 can help absorb the tolerance and clamp the MT ferrule assembly 2 in a fixed position, thereby ensuring that the optical axis plane of the MT ferrule assembly 2 coincides with the optical axis plane of the MPO buckle 1 after the MT ferrule assembly 2 is inserted into the MPO buckle 1, so that the optical axis plane of the MT ferrule assembly 2 coincides with the optical axis plane of the MPO buckle 1, so that the optical axis plane of the MT ferrule assembly 2 is consistent with the optical axis plane of the MPO plug 3 plugged in the MPO buckle 1. The two slopes 121 of the two cantilevers 120 are distributed in an eight-shaped shape and the bundle end faces the plug-in portion 110;

[0033] A limiting portion 140 is arranged on both sides of each cantilever 120 along its length direction, which is close to the side of the MT ferrule assembly 2. The limiting portion 140 is fixedly connected to the plug-in portion 110. The insertion position and direction of the MT ferrule assembly 2 can be limited by the four limiting portions 140 to ensure that the MT ferrule assembly 2 and the MPO plug 3 can be accurately coupled.

[0034] The MPO buckle 1 is designed to be pop-openable. By plugging the MT ferrule assembly 2 into the pop-open MPO buckle 1 and ensuring that the optical axis plane of the MT ferrule assembly 2 coincides with the optical axis plane of the MPO buckle 1, when the MPO plug 3 is plugged and matched with the MPO buckle 1, the MT ferrule assembly 2 and the MPO plug 3 can be accurately coupled without the aid of any other auxiliary structure (that is, without relying on the compression effect of the upper structure and the lower structure 4 to achieve coupling), the docking efficiency of the MPO plug 3 and the MT ferrule assembly 2 is effectively improved, and the optical power is increased. In addition, the structure can be used as a separate MPO plug 3 and MT ferrule assembly 2 docking test device to optimize the test link.

[0035] Example 2

[0036] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on the basis of embodiment 1, and the details are as follows:

[0037] The inner side surface of each cantilever 120 includes: a first horizontal section 122, a slope 121 and a second horizontal section 123 connected in sequence. The first horizontal section 122 is close to the undercut 130. The inner side surface of the cantilever 120 can adapt to the shape of the MT ferrule assembly 2, so as to stably clamp the MT ferrule assembly 2 to prevent the MT ferrule assembly 2 from loosening, and also facilitate the insertion and removal of the MT ferrule assembly 2.

[0038] Furthermore, a guide angle 131 is provided on the side of each undercut 130 facing away from the plug-in portion 110 , so as to facilitate the insertion of the MT ferrule assembly 2 between the two cantilevers 120 .

[0039] The MPO buckle 1 is integrally formed by an injection molding process, and GF (glass fiber) is added to the injection molding material of the MPO buckle 1 to enhance the strength, rigidity and toughness of the undercut 130 and improve the resilience.

[0040] Example 3

[0041] like Figure 5 , Figure 6 , Figure 7As shown, an optical module includes: an upper structural member, a lower structural member 4, and an MPO latch-MT docking device. The upper structural member and the lower structural member 4 are fixedly connected by screws. The MPO latch 1 and the MT ferrule assembly 2 are clamped by the upper structural member and the lower structural member 4, and the precise coupling between the MT ferrule assembly 2 and the MPO plug 3 can be achieved without relying on the pressing action of the upper structural member and the lower structural member 4.

[0042] Furthermore:

[0043] As Figure 5 shown, the MPO latch 1 and the MT ferrule assembly 2 are horizontally distributed between the upper structural member and the lower structural member 4, that is, the MPO latch-MT docking device 1 is horizontally distributed between the upper structural member and the lower structural member 4.

[0044] As Figure 6 shown, the MPO latch 1 and the MT ferrule assembly 2 are vertically distributed between the upper structural member and the lower structural member 4, that is, the MPO latch-MT docking device 1 is vertically distributed between the upper structural member and the lower structural member 4.

[0045] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
