Signal connection structure based on shape protection, assembling method thereof and packaging box body

Abstract

The invention discloses a signal connection structure based on shape protection, an assembling method thereof and a packaging box body, and the signal connection structure comprises a housing which isprovided with a connector installation hole; and signal connector which is used for being mounted in the connector installation hole and comprises a connector shell, wherein the connector shell is ina shape with a wide bottom and a narrow top, and the shape of the connector installation hole is matched with the shape of the connector shell. When the connector is subjected to external pulling force, most pulling force is borne due to the blocking of the shape of the shell, so that the pulling force borne by the welding position of the circuit board and the signal connector is reduced, the connection strength is improved, and the signal connector is protected; and in addition, due to the fact that the bottom of the connector shell is wide and the top of the connector shell is narrow, no linear gap exists between the signal connector and the shell, the possibility of light leakage is greatly reduced, photons cannot pass through smoothly, the shading effect is achieved, and therefore theeffects of avoiding light leakage and enhancing connection firmness are achieved at the same time.

AI Technical Summary

Problems solved by technology

[0004] The technical difficulty is that the connector that seems to be well connected to the box at room temperature, in an extremely low temperature environment, due to the different characteristics of the thermal expansion coefficient of the material, will cause the material to separate and cause light leakage (the leakage of a single photon is enough to make the quantum processor receives considerable noise), which seriously affects the operation of the quantum processor

On the other hand, due to the separation of materials caused by different thermal expansion coefficients of materials, it is easy to deteriorate the connection strength between the connector and the circuit board, and it is easy to detach during the plugging and unplugging process of the connector, resulting in damage to the connector and even the packaging shell.
