Physical package of miniature atomic clock

Abstract

The invention relates to a physical package of a miniature atomic clock. The physical package comprises a photoelectric detector and a circuit board thereof, a thermosensitive resistor, a photoelectric detector circuit board bonding pad pin, an MEMS alkalis steam bubble, a 1 / 4 wave plate, a field-effect transistor, a laser and a circuit board thereof, a C-axis magnetic field coil brace, a magnetic shielding shell, a physical package main body support and a bolt lock, wherein the physical package main body support is used for assembling the photoelectric detector and the circuit board thereof, the thermosensitive resistor, the photoelectric detector circuit board bonding pad pin, the MEMS alkalis steam bubble, the 1 / 4 wave plate, the field-effect transistor and the laser and the circuit board thereof together; a plurality of bolt holes are formed in two sides of the physical package main body support, the bolt lock is provided with a plurality of bolts of which the quantity is the same as that of the plurality of bolt holes, and the bolts pass through the plurality of bolt holes to fix positions of the photoelectric detector and the circuit board thereof and the laser and the circuit board thereof. According to the physical package of the miniature atomic clock of the invention, the difficulty of achieving the physical package of the miniature atomic clock can be lowered, and the mechanical firmness of the whole structure is enhanced by fixing discrete devices in the physical package main body support.

Description

technical field [0001] The invention relates to a physical package technology of a miniaturized atomic clock, in particular to a physical package of a miniaturized atomic clock. Background technique [0002] The atomic clock is currently the most accurate time or frequency device in the world, but its large size, high power consumption, and high price limit its scope of use. Miniaturized atomic clocks are becoming more and more popular because of their small size, low power consumption and relatively low price. [0003] Miniaturized atomic clock includes three parts: radio frequency module, servo control loop and physical packaging, among which physical packaging is the core and most difficult part. Contents of the invention [0004] The purpose of the present invention is to solve the problem of physical packaging of miniaturized atomic clocks in the prior art, and provide a physical packaging of miniaturized atomic clocks, which reduces the difficulty of realizing physi...
