Description

Technical Field

[0001] The utility model relates to the technical field of TO tube sockets, in particular to a novel TO tube socket. Background Art

[0002] TO package is a common packaging method for transistor components, mainly including tube holders and tube caps. By fixing optical components in sealed tube holders and tube caps, it protects easily damaged optical components. At present, the 2.5G TO tube holders in the industry can only be used for 10G optical modules at most. Due to the limitation of its own bandwidth, it cannot be used for 25G or higher-speed optical modules. In addition, the TO tube holders currently used in 25G or higher-speed optical modules have high usage costs and are not suitable for the long-term development needs of enterprises.

[0003] In view of the above situation, it is necessary to improve the existing TO tube holder so that it can meet the current needs of using optical modules. Utility Model Content

[0004] The utility model aims to solve the above problems and designs a novel TO tube socket.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is a novel TO tube seat, comprising a mounting seat, a PCB board arranged on the mounting seat, and a laser chip arranged on the upper end of the PCB board, the mounting seat is provided with a through mounting hole for installing a PIN needle, the mounting seat comprises a first connecting part and a second connecting part, the PCB board is arranged on the second connecting part, and the second connecting part is arranged on one side of the first connecting part and connected thereto.

[0006] As a further supplement to the technical solution, through mounting holes are symmetrically provided on the left and right sides of the mounting seat.

[0007] As a further supplement to the technical solution, the cross-section of the second connecting portion is concave-shaped.

[0008] As a further supplement to the technical solution, the second connecting portion is arranged at a position corresponding to the mounting hole in an arc shape and is coaxial with the mounting hole.

[0009] As a further supplement to the technical solution, the first connecting portion is arranged horizontally, and the second connecting portion is arranged on the plane of the first connecting portion.

[0010] The beneficial effect is that, compared with the ordinary 25G TO, this technical solution adopts the glass body and PIN needle of 2.5G TO to reduce the cost; low cost, high yield, easy rework; the structure of the mounting seat and PIN needle is changed to improve the impedance discontinuity of the entire TO.

[0014] In order to make the technical solution more clear to those skilled in the art, Figure 1-2 The technical solution of the utility model is described in detail:

[0015] A novel TO tube seat comprises a mounting seat 1, a PCB board 2 arranged on the mounting seat 1, and a laser chip 3 arranged on the upper end of the PCB board 2. The mounting seat 1 is provided with a through mounting hole 4 for installing a PIN needle 5. The mounting seat 1 comprises a first connecting part 11 and a second connecting part 12. The PCB board 2 is arranged on the second connecting part 12, and the second connecting part 12 is arranged on one side of the first connecting part 11 and connected thereto. The technical scheme changes the structure of the mounting seat 1, and the corresponding design of the first connecting part 11 and the second connecting part 12 improves the impedance discontinuity of the entire TO.

[0016] Among them, through mounting holes 4 are symmetrically provided on the left and right sides of the mounting seat 1.

[0017] The structure of the mounting base 1 will be described in detail below, wherein the second connection portion 12 has a concave cross-section, wherein the first connection portion is arranged horizontally, and the second connection portion is arranged on the plane of the first connection portion.

[0018] The second connection portion 12 is arranged at a position corresponding to the mounting hole 4 in an arc shape and is coaxial with the mounting hole 4 , so as to facilitate the installation of the PIN needle 5 .

[0019] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
