With the continuous development of 25G optical communication, the requirements for TO headers are also constantly increasing, requiring support for higher data transmission rates, including higher bandwidth and lower transmission latency. At the same time, the requirements for TO header packaging also tend to be smaller in size. The existing TO headers are large in volume and high in cost, and do not meet the needs of the rapid development of 25G optical communication. Summary of the Utility Model

The gap between the pin and the independent through-hole is filled with a first glass insulator. A continuous through-hole is further provided on the bottom plate. The continuous through-hole is symmetric about a first symmetry center plane in its length direction and symmetric about a second symmetry center plane in its width direction. Two continuous through-hole pins are fixedly provided in the continuous through-hole. The two continuous through-hole pins are symmetric about the first symmetry center plane, and the distances from the centers of the two continuous through-hole pins to the center of the bottom plate are equal. The gap between the two continuous through-hole pins and the continuous through-hole is filled with a second glass insulator.

Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] The purpose of the present utility model is to provide a TO header to solve the problems existing in the prior art, with a relatively simple structure, small volume, low cost, high transmission efficiency, easy to manufacture and test, and conducive to large-scale production.

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1 As shown, the utility model provides a TO tube holder, including a base plate 1, a connected through-hole pin 2 and a pin 3. A plurality of independent through-holes 4 are provided on the base plate 1, and a pin 3 is fixed in each independent through-hole 4. A first glass insulator 5 is filled in the gap between the pin 3 and the independent through-hole 4. A connected through-hole 6 is also provided on the base plate 1. The connected through-hole 6 is symmetrical about a first symmetry center plane in its length direction and symmetrical about a second symmetry center plane in its width direction. Two connected through-hole pins 2 are fixed in the connected through-hole 6. The two connected through-hole pins 2 are symmetrical about the first symmetry center plane. The centers of the two connected through-hole pins 2 are equidistant from the center of the base plate 1. The gap between the two connected through-hole pins 2 and the connected through-hole 6 is filled with a second glass insulator 7.

[0022] In this embodiment, the pin 3 is fixed in the independent through hole 4 through the first glass insulator 5. The two conjoined through hole pins 2 are fixed in the conjoined through hole 6 through the second glass insulator 7. The glass insulator is used to fix the pin 3 and the conjoined through hole pin 2, and at the same time plays an insulating role, which is convenient and quick to manufacture.

[0023] In this embodiment, the integrated through-hole pin 2 protrudes from the surface of the second glass insulator 7 by 0.10 mm-0.55 mm, and the diameter of the integrated through-hole pin 2 is 0.20 mm-0.25 mm, which is easy for customers to wire. If the pin is too high or too thin during wiring, it will shake and affect the wiring.

[0024] In this embodiment, the cross-sectional shapes and sizes of the connected through holes 6 are consistent at all locations.

[0025] In this embodiment, the length of the conjoined through hole 6 is 1.2mm-3.0mm, and the width is 0.5mm-1.6mm. The distance between the center of the two conjoined through hole pins 2 and the center of the bottom plate 1 is 0.25mm-1.6mm. On the premise that the material of the second glass insulator 7 remains unchanged, the independent through hole is changed into a conjoined through hole, which increases the area that can be filled with glass, can better cooperate with the client application, and improve the transmission rate.

[0026] In this embodiment, the independent through hole 4 is a circular hole, and the pin 3 and the independent through hole 4 are coaxial.

[0027] In this utility model, specific examples are used to elaborate on the principle and implementation mode of the utility model. The description of the above embodiments is only used to help understand the method and its core idea of the utility model; at the same time, for those of ordinary skill in the art, according to the idea of the utility model, there will be changes in the specific implementation mode and application scope. To sum up, the content of this specification should not be construed as a limitation to the utility model.
