Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0021] like Figures 1-11 As shown, this utility model discloses an optical component, including an adapter 10, a TO optical device, an optical fiber 30, and an assembly housing 40.
[0022] The adapter 10 is a single piece, which can be integrally formed through processing technology.
[0023] The adapter 10 has an internal mounting cavity 11, a ceramic sleeve 12 and a connecting cavity 13. A through hole 14 connects the mounting cavity 11 and the ceramic sleeve 12. The ceramic sleeve 12 and the connecting cavity 13 are connected. The inner diameter of the ceramic sleeve 12 is smaller than the inner diameter of the connecting cavity 13.
[0024] The ceramic sleeve 12 is embedded in the adapter 10, which can reduce the difficulty and cost of mold opening of the adapter 10 and meet the micron-level high precision requirements of the optical connector optical interface.
[0025] The TO optical device 20 includes a cap 21, which fits inside the mounting cavity 11; the outer wall of the cap 20 is provided with a lens 22, which corresponds to the through hole 14.
[0026] The TO optical device 20 includes a base 23, and a cap 21 is connected to the base 23.
[0027] like Figure 10 As shown, in one embodiment of this application, a chip 24 and a ceramic block 25 are provided on the base 23. The chip 24 can be a VCSEL chip, and the optical component of this application is a light emitting component.
[0028] like Figure 11 As shown, in another embodiment of this application, a chip 24 is provided on the base 23. The chip 24 can be a photosensitive IC chip. In this case, no ceramic block 25 is provided on the base 23, and the optical component of this application is a light receiving component.
[0029] One end of the optical fiber 30 is provided with a ceramic ferrule 31 and a ferrule fixing platform 32. The ceramic ferrule 31 is inserted into the ceramic sleeve 12, and the ferrule fixing platform 32 is inserted into the connection cavity 13.
[0030] The outer wall of the connecting cavity 13 is provided with a guide groove 16, and the outer wall of the ferrule fixing platform 32 is provided with a protruding guide post 33, which fits into the guide groove 16. Through the cooperation of the guide post 33 and the guide groove 16, the connection between the optical fiber 30 and the adapter 10 can be guided, avoiding incorrect installation of the optical fiber 30, and improving the installation efficiency and accuracy of the optical fiber 30.
[0031] The opening of the guide groove 16 is provided with two inlet surfaces 17. The angle between the inlet surface 17 and the side wall of the guide groove 16 is an obtuse angle, which can guide the guide post 33 to be inserted into the guide groove 16 more smoothly and accurately.
[0032] The assembly shell 40 is a single piece, which can be integrally formed through processing technology.
[0033] The assembly housing 40 is connected to the outer wall of the connection cavity 13 and is used to lock the optical fiber 30 onto the adapter 10.
[0034] Specifically, the assembly shell 40 has an inner cavity, the inner diameter of which is larger than the outer diameter of the connecting cavity 13, and the connecting cavity 13 is inserted into the inner cavity of the assembly shell 40.
[0035] The outer wall of the connecting cavity 13 is provided with a protruding locking post 15, and the shell wall of the assembly shell 40 is provided with a first sliding groove 41, a second sliding groove 42 and a locking groove 43 connected in sequence; wherein, the first sliding groove 41 and the second sliding groove 42 are connected to form an L-shape, and the ends of the locking groove 43 and the second sliding groove 42 are connected. The locking groove 43 can be arc-shaped, and the corresponding locking post 15 can be cylindrical, so that the locking post 15 and the locking groove 43 can be adapted to each other and more effectively locked together. The locking post 15 can slide from the first sliding groove 41 into the second sliding groove 42 and lock with the locking groove 43.
[0036] The connecting cavity 13 is inserted into the inner cavity of the assembly shell 40, and the engaging post 15 can slide into the first sliding groove 41. Then, the assembly shell 40 or the adapter 10 is rotated so that the engaging post 15 slides into the second sliding groove 42. Then, the assembly shell 40 is pulled outward so that the engaging post 15 can slide into and engage in the engaging groove 43, thereby realizing the engaging connection between the assembly shell 40 and the adapter 10.
[0037] In one embodiment of this application, there are two engaging posts 15, which are symmetrically arranged on both sides of the guide groove 16; the corresponding number of first sliding grooves 41, second sliding grooves 42, and engaging grooves 43 are all two. Through the cooperation of the guide posts 33 and the guide grooves 16, the connection between the assembly shell 40 and the adapter 10 can be guided, avoiding incorrect installation of the assembly shell 40.
[0038] A limiting plate 44 is fixed inside the assembly shell 40. The limiting plate 44 is parallel to the radial direction of the assembly shell 40. The limiting plate 44 is provided with a through hole 45 for the optical fiber 30 to pass through.
[0039] like Figure 2 As shown, a spring 34 is fitted on the optical fiber 30. When the optical fiber 30 is connected inside the adapter 10 and the adapter 10 is connected to the assembly housing 40, the spring 34 is compressed and abuts against the limiting plate 44 and the ferrule fixing platform 32. On the one hand, a rightward pulling force can be applied to the assembly housing 40 to strengthen the locking force between the locking post 15 and the locking groove 43, and to strengthen the connection stability between the assembly housing 40 and the adapter 10. On the other hand, it can enhance the stability and reliability of the installation of the optical fiber 30, so that the optical fiber 30 can be locked and connected to the adapter 20.
[0040] The outer wall of the assembly housing 40 is provided with protruding locking teeth 46, which can increase the friction and facilitate the rotation and locking of the assembly housing 40.
[0041] The optical fiber 30 is provided with a pigtail sheath 35, which can protect the optical fiber 30 and prevent it from being broken due to excessive stress.
[0042] Fiber 70 is a high-temperature resistant fiber with a temperature range of -55℃ to 130℃, which can meet the application requirements of harsh temperature environments.
[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
