[0035] See also Figure 1-6A high-speed photodetector TO packaging structure includes a tube seat 1, a clamp 2, a tube cap 3, a limiter 1 4, a limiter 2 5, a mounting seat 6 and a lens 7. The clamp 2 is distributed on the tube seat 1 in a ring array, the tube cap 3 is arranged on the tube seat 1, the limiter 1 4 is arranged between the tube seat 1 and the clamp 2 through the tube cap 3, the limiter 2 5 is distributed in a ring array between the tube seat 1 and the tube cap 3, the mounting seat 6 is arranged between the tube seat 1 and the tube cap 3, and is located above the clamp 2, and the lens 7 is arranged between the mounting seat 6 and the tube cap 3.

[0036] Based on the above, in this embodiment, the lens 7 is positioned on the tube seat 1 through the mounting seat 6, and is located directly above the packaging component. Then the tube cap 3 is docked with the tube seat 1 and is connected and fixed by the limit piece 2 5. At the same time, the limit piece 1 4 is combined with the clamping piece 2 for reinforcement. When the tube cap 3 is fixed on the tube seat 1, the tube cap 3 is close to and combined with the mounting seat 6 to indirectly fix the lens 7, so that the tube cap 3 and the lens 7 can be detachably connected. By operating the limit piece 2 5 to contact the connection limit between the tube cap 3 and the tube seat 1, and then pulling the tube cap 3 to drive the limit piece 1 4 to separate from the clamping piece 2 and detach from the mounting seat 6, finally the lens 7 is removed, and multiple components can be disassembled and replaced conveniently.

[0037] See also Figure 1-6 The tube seat 1 includes a mounting platform 11, a convex edge 12 and a pin 13. The convex edge 12 is arranged on the outer edge of the mounting platform 11, and the pin 13 is arranged on the mounting platform 11. A convex edge 2 is arranged on the outer edge of the tube cap 3, and the convex edge 2 is located above the convex edge 12. The convex edge 12 is provided with a socket located below the convex edge 2.

[0038] Based on the pipe cap 3 being covered on the pipe base 1, and then fixedly connected by the limit pieces 2 5 and the limit pieces 1 4 at different positions, the pipe base 1 forms a combination of the mounting platform 11 and the convex edge 1 12 with high and low levels, so that the pipe cap 3 is docked and lowered and first moves along the outer edge of the mounting platform 11. After the convex edge 2 abuts against the convex edge 1 12, the pipe cap 3 and the pipe base 1 are docked. Subsequently, the convex edge 12 and the convex edge 2, and the pipe cap 3 and the mounting platform 11 are fixed by the limit pieces 2 5 and the limit pieces 1 4.

[0039] The above-mentioned pipe cap 3 and the mounting platform 11 are fixed by a limiting member 4. The clamping member 2 in this embodiment includes a bending portion 21 arranged on the mounting platform 11, and a top supporting portion 22 is arranged on the bending portion 21. The limiting member 4 is arranged in the pipe cap 3, the limiting member 4 is adapted to the top supporting portion 22, and the limiting member 4 is in contact with the bending portion 21 and the mounting platform 11.

[0040] As the pipe cap 3 is lowered and moves along the mounting platform 11, a limiting member 4, which is preferably a rubber product, follows and first contacts the top support portion 22. During the continuous lowering movement, the limiting member 4 presses the top support portion 22 inward, and then passes through the top support portion 22 and enters between the bending portion 21 and the mounting platform 11. In this way, the limiting member 4 is confined between the bending portion 21 and the mounting platform 11 to reinforce the pipe cap 3.

[0041] See also Figure 1-6 The second limiting member 5 is arranged between the convex edge 12 and the second convex edge through the insertion hole. The second limiting member 5 includes a positioning portion 51 arranged on the second convex edge. The positioning portion 51 is located in the insertion hole. A fixing portion 52 is arranged on the positioning portion 51. One end of the fixing portion 52 extends out of the insertion hole and contacts the convex edge 12.

[0042] It should be noted that after the convex edge 12 contacts the convex edge 2, the positioning portion 51 made of the same rubber material as the limiter 4 is squeezed into the socket to limit the contact between the convex edge 12 and the convex edge 2, and the fixing portion 52 that moves through the socket adopts a structure similar to a presser foot. By applying force in the direction of the convex edge 12, the fixing portion 52 is bent and contacts the convex edge 12, thereby achieving a fixed connection between the convex edge 12 and the convex edge 2, and indirectly fixing the pipe cap 3 and the pipe seat 1.

[0043] See also Figure 1-6 The mounting seat 6 includes a supporting sleeve 61, a positioning foot 62 and a positioning column 63. The supporting sleeve 61 is engaged with the top support portion 22 through the positioning foot 62. The positioning column 63 is arranged on the positioning foot 62. A slot is provided on the mounting platform 11. The positioning column 63 is located in the slot. A card slot is provided on the pipe cap 3. A supporting protrusion is provided on the supporting sleeve 61. The supporting protrusion is located in the card slot. The lens 7 is arranged in the card slot through the supporting protrusion.

[0044] Based on the above-mentioned detachable connection between the lens 7 and the tube cap 3, the support sleeve 61 of this embodiment is installed on the mounting platform 11 by setting positioning feet 62 corresponding to the number of intervals of the clamping parts 2, and the positioning feet 62 are inserted between the clamping parts 2. When the positioning feet 62 are completely matched with the clamping parts 2, the positioning column 63 is pressed into the slot to complete the connection between the support sleeve 61 and the mounting platform 11. Then, the lens 7 is placed on the supporting protrusion and positioned directly above the mounting platform 11 by the support sleeve 61. Then, it is connected to the tube seat 1 from the bottom of the tube cap 3 and fixed with the support sleeve 61.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
