Embodiment 1
[0025] according to figure 1 , figure 2 It can be seen that a spectrum lamp for rubidium atomic frequency standard is composed of sapphire glass sheet 1, lamp cover 2, heating coil 3, transition circuit board 4, rubidium bulb 5, coupling coil 6, temperature sensing element 7, lamp bracket 8, and The axis 9, the shielding box 10 and the radio frequency circuit board 11 constitute. It is characterized in that: the sapphire glass sheet 1 is bonded in the glass sheet bayonet 2a on the top of the lamp cover 2 through silicon rubber, and is the light-through window of the spectrum lamp. The coupling coil 6 is a metal coil tightly wound on the top of the bulb 5, one end of which is welded to the core wire of the coaxial line 9, and the other end is welded to the outer wall of the coaxial line 9. The coaxial line passes through the lamp cap 2 , the transition circuit board 4 , the shielding box 10 and the radio frequency circuit board 11 . The bulb 6 is a glass bulb filled with a ...
