DETAILED DESCRIPTION

[0026] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0027] like Figure 1-Figure 8 The first embodiment of the utility model provides an MT-MT quick-release buckle, including a buckle body 6. Along the length direction of the buckle body 6 (the plug-in direction of the MT male head 4 and the MT female head 5), an elastic connecting portion 17 is provided in the middle of the buckle body 6, and elastic abutting portions are provided at both ends of the buckle body 6. The two elastic abutting portions are connected by the elastic connecting portion 17. The elastic abutting portions include two elastic top feet 9. The elastic top feet 9 are S-shaped. The elastic top feet 9 include a first arc elastic segment 11 for abutting against the MT connector (MT male head 4, MT female head 5), and a second arc for increasing the elastic deformation stroke of the first arc elastic segment 11. The elastic segment 12, one end of the second circular arc elastic segment 12 is tangentially connected to the first circular arc elastic segment 11, which can realize a larger elastic deformation stroke of the elastic top feet 9 at both ends along the length direction of the buckle body, and the other end of the second circular arc elastic segment 12 is connected to the elastic connecting portion 17. Along the width direction of the buckle body 6, there is an avoidance gap 13 between the two elastic top feet 9 of an elastic abutment portion, and the avoidance gap 13 is for the optical fiber sheath 8 of the MT connector to extend into. The avoidance gap 13 is greater than the thickness of the optical fiber sheath 8 of the MT connector (MT male head 4, MT female head 5), and is also greater than the outer diameter of the PIN needle 7 of the MT male head 4. The width direction of the buckle body 6, that is, Figure 4 The vertical direction is the length direction of the buckle body 6. Figure 4 In the left and right directions, the elastic connecting portion 17 is provided with an elastic protruding angle 14, so that the gap between the two elastic abutting portions can be adjusted during manufacturing, so that the buckle has better manufacturability; it is also beneficial to achieve a larger elastic deformation stroke of the elastic top feet 9 at both ends along the length direction of the buckle body, and the elastic protruding angle 14 protrudes along the side away from the elastic top foot 9.

[0028] In this embodiment, the buckle body 6 is formed of sheet metal in one piece. Along the length direction of the buckle body 6, the elastic protruding corner 14 is arranged at the middle position of the elastic connecting portion 17. Along the width direction of the buckle body 6, two elastic top feet 9 of an elastic abutment portion are arranged opposite to each other.

[0029] The second embodiment of the utility model provides an MT-MT docking structure, including two MT connectors, namely, an MT male connector 4 and an MT female connector 5. The MT male connector 4 and the MT female connector 5 can both be 12-core MT connectors or 16-core MT connectors. The MT male connector 4 and the MT female connector 5 are plug-in connected. The MT female connector 5 is electrically connected to the device end, and the MT male connector 4 is electrically connected to the optical module end. The MT-MT docking structure also includes the above-mentioned MT-MT quick-release buckle. Along the length direction of the buckle body 6, the optical fiber sheath 8 of the MT male connector 4 is inserted between the two elastic top feet 9 at one end, and the optical fiber sheath 8 of the MT female connector 5 is inserted between the two elastic top feet 9 at the other end. The end of the MT male connector 4 away from the MT female connector 5 is provided with a plug-in connection with the elastic top foot. 9, one end of the MT female connector 5 away from the MT male connector 4 is provided with two second abutment points cooperating with the elastic top feet 9, along the length direction of the buckle body 6, the two elastic top feet 9 at one end abut with the two first abutment points one by one, and the two elastic top feet 9 at the other end abut with the two second abutment points one by one, along the length direction of the buckle body 6, the spacing between the elastic top feet 9 at both ends of the buckle body is smaller than the spacing between the first abutment point and the second abutment point, so that after the buckle body 6 is installed on the MT male connector 4 and the MT female connector 5, elastic deformation will occur, and the MT male connector 4 and the MT female connector 5 are pressed tightly by their own elastic deformation, so that the MT male connector 4 and the MT female connector 5 after plugging are not easy to loosen.

[0030] In this embodiment, the MT male connector 4 and the MT female connector 5 both include a sheet metal housing 10, the first abutment point is provided on the sheet metal housing of the MT male connector 4, and the second abutment point is provided on the sheet metal housing of the MT female connector 5. In this embodiment, a first abutment groove is provided on the sheet metal housing 10 of the MT male connector 4, the first abutment point is provided in the first abutment groove, and a second abutment groove is provided on the sheet metal housing 10 of the MT female connector 5, and the second abutment point is provided in the second abutment groove.

[0031] Due to the frequent docking and disassembly of the MT male connector 4 and the MT female connector 5, as well as the weight of the MT male connector 4 and the MT female connector 5, the plugged MT male connector 4 and the MT female connector 5 may suddenly loosen and have poor contact, or be completely disconnected during the FA coupling test of the optical engine, which will have a great impact on the efficiency and yield of the FA coupling test of the optical engine. The utility model provides an MT-MT quick-release buckle, which can not only effectively fix the MT male connector 4 and the MT female connector 5 when the MT male connector 4 and the MT female connector 5 are plugged in, so that the MT male connector 4 and the MT female connector 5 are effectively connected, but also avoid the problem of poor contact of the MT male connector 4 and the MT female connector 5 due to looseness, or the problem of complete disconnection of the MT male connector 4 and the MT female connector 5; the utility model can ensure the efficiency and yield of the FA coupling test of the optical engine, so that the FA coupling test of the optical engine can be carried out smoothly.

[0032] The MT-MT quick-release buckle provided by the utility model can ensure reliable connection between the MT male connector 4 and the MT female connector 5. The buckle is easy to install and disassemble and has the advantage of being lightweight. Therefore, when the device is clamping the FA and coupling the optical engine, the movement of the coupling device and the stability of the clamping will not be affected by the pulling caused by the excessive weight of the buckle.

[0033] When the MT male connector 4 and the MT female connector 5 are plugged together, the quick-release buckle can effectively fix the two MT connectors (MT male connector 4 and MT female connector 5) without damaging the MT connector. The installation of the buckle can be self-positioned through the PIN needle 7 of the MT male connector 4 and the BOOT (optical fiber sheath 8) of the MT female connector 5, and there is no requirement for the installation direction of the buckle.

[0034] The four elastic pins 9 of the buckle are pressed against the sheet metal housings 10 of the two MT connectors (MT male connector 4 and MT female connector 5), and the MT male connector 4 and the MT female connector 5 are limited and clamped by their own rebound.

[0035] Figure 1 The figure is a schematic diagram of the existing MPO optical module MT-FA coupling test, where the MT female connector 5 is electrically connected to the device end, and the MT male connector 4 is electrically connected to the optical module end. The utility model realizes the lightweight, high degree of freedom and stability of the docking of the MT male connector 4 (module end) and the MT female connector 5 (device end) required when coupling the optical engine of the MPO module. The efficiency of FA coupling in the module optical engine is improved.

[0036] Figure 2-Figure 5 The utility model provides an MT-MT quick-release buckle, which is integrally formed of sheet metal and has four elastic top feet 9, and realizes the compression of MT-MT (MT male head 4 and MT female head 5) through its own elastic deformation.

[0037] Figure 6 This is a schematic diagram of the working of the buckle of the utility model on a 12-core MT. The MT male connector 4 and the MT female connector 5 are clamped by the buckle to complete the stability of the optical path during the test.

[0038] Along the length direction of the buckle body 6, the gap between the two elastic top feet 9 located at the same end of the buckle body 6 should be greater than the thickness of the optical fiber sheath 8 of the MT male connector 4 and the thickness of the optical fiber sheath 8 of the MT female connector 5, so that the optical fiber sheath 8 can extend between the two elastic top feet 9. The optical fiber sheath 8 plays a positioning role in the installation of the buckle. The PIN needle 7 at the end of the MT male connector 4 away from the MT female connector 5 is also located between the two elastic top feet 9, which can also play a positioning role in the installation of the buckle. The gap between the two elastic top feet 9 located at the same end of the buckle body 6 should be greater than the outer diameter of the PIN needle 7.

[0039] Figure 7The figure is a schematic diagram of the working state of the clip of the utility model on the 16-core MT. The clip provided by the utility model can be used for two types of MT connectors: 12-core MT and 16-core MT.

[0040] Figure 8 This is a schematic diagram of the buckle assembly of the utility model. After the MT male connector 4 and the MT female connector 5 are aligned and plugged through the PIN pin 7, the buckle is installed on the MT male connector 4 and the MT female connector 5. The optical fiber sheath 8 of the MT male connector 4 and the optical fiber sheath 8 of the MT female connector 5 extend into their corresponding avoidance gaps 13. Along the length direction of the buckle, the elastic top foot 9 at one end supports the sheet metal shell 10 of the MT male connector 4, and the elastic top foot 9 at the other end supports the sheet metal shell 10 of the MT female connector 5, realizing the limit and clamping of MT-MT (MT male connector 4 and MT female connector 5). When the test is completed, the buckle 101 can be directly pulled out from the MT-MT (MT male connector 4 and MT female connector 5) to achieve the quick release requirement.
