Description

Technical Field

[0001] The utility model relates to the technical field of rubidium atomic clocks, and particularly relates to a rubidium atomic clock with quick installation and reliable structure. Background Art

[0002] The rubidium atomic clock combines a high-stability rubidium oscillator with GPS high-precision time service, frequency measurement and time synchronization technologies. It makes the output frequency of the rubidium oscillator tamed and synchronized with the GPS satellite cesium atomic clock signal, improving the long-term stability and accuracy of the frequency signal. It can provide a high-precision time and frequency standard at the cesium clock level and is a high-cost-effective product to replace cesium clocks in departments such as communication and radio and television.

[0003] The existing rubidium atomic clock mainly consists of a low-frequency connector, an interface baffle, a radio-frequency connector, an interface baffle fixing plate, a base, a housing and an internal circuit. When assembling the rubidium atomic clock with this structure, the internal circuit integrated with the low-frequency connector and the radio-frequency connector is first installed on the base, and the interface baffle fixing plate is installed on the internal circuit. Then, the interface baffle is installed on the interface baffle fixing plate, and screws are used to fasten the interface baffle and the interface baffle fixing plate. Next, the housing is placed on the base, and finally, screws are used for fastening. Although the assembly of the rubidium atomic clock can be achieved in the above installation method, a lot of time is wasted in fixing the interface baffle and the interface baffle fixing plate during the installation process, resulting in a more cumbersome overall assembly process of the rubidium atomic clock and a lower assembly efficiency.

[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] As Figure 1As shown in the figure, a rubidium atomic clock with fast installation and reliable structure in this embodiment includes a base 1. A lining plate 3 is installed around the upper end of the base 1. An internal circuit board 4 is installed between the lining plates 3 on the base 1. A radio frequency connector 5 is installed on one side of the internal circuit board 4. A low-frequency connector 6 is installed on the internal circuit board 4 on the side of the radio frequency connector 5. An outer shell 2 is also arranged on the upper side of the internal circuit board 4. A first limiting mounting hole 8 is opened on the outer shell 2 opposite to the radio frequency connector 5. A second limiting mounting hole 7 is opened on the outer shell 2 opposite to the low-frequency connector 6. The size of the first limiting mounting hole 8 matches the size of the radio frequency connector 5. The radio frequency connector 5 penetrates through the first limiting mounting hole 8, which can ensure that the radio frequency connector 5 can pass through the first limiting mounting hole 8 conveniently when the outer shell 2 is installed. The size of the second limiting mounting hole 7 matches the size of the low-frequency connector 6. The low-frequency connector 6 penetrates through the second limiting mounting hole 7, which can ensure that the low-frequency connector 6 can pass through the second limiting mounting hole 7 conveniently when the outer shell 2 is installed. The outer shell 2 and the base 1 are locked and fixed by bolts.

[0027] As Figure 1 shown in the figure, in this embodiment, the lining plate 3 is bolted to the base 1. There are four lining plates 3. The lining plates 3 can ensure the reliable installation and fixation of the internal circuit board 4 on the base 1. The internal circuit board 4 is bolted to the base 1. The internal circuit board 4 is electrically connected to both the radio frequency connector 5 and the low-frequency connector 6. Both the radio frequency connector 5 and the low-frequency connector 6 are integrated on the internal circuit board 4.

[0028] As Figure 1 shown in the figure, in this embodiment, a gap is reserved at the edge between the lining plate 3 and the base 1, and the gap matches the thickness of the bottom side wall of the outer shell 2, which can ensure that the outer shell 2 is closely attached to the edge of the base 1 after being closed on the base 1. The bottom of the outer shell 2 is of an open structure, ensuring that the internal circuit board 4 can be reliably protected after the outer shell 2 is installed.

[0029] The specific implementation process of this embodiment is as follows: When assembling the rubidium atomic clock, first install the lining plate 3 on the base 1, then install the internal circuit board on the base 1. Then, with an included angle of 45° between the outer shell 2 and the base 11, align the first limiting mounting hole 8 on the outer shell 2 with the radio frequency connector 5 and align the second limiting mounting hole 7 with the low-frequency connector 6. Then push the radio frequency connector 5 and the low-frequency connector 6 between the outer shell 2 and the base 1. Then slowly rotate the outer shell 2 until the upper edge parts of the outer shell 2 and the base 1 are in contact. Finally, use screws to fasten the outer shell 2 and the base 1, and the assembly of the rubidium atomic clock can be completed. Since in the above assembly process, the quick installation and limitation between the outer shell 2 and the low-frequency connector 6 and the radio frequency connector 5 can be realized without using the interface baffle and the interface baffle fixing plate, the entire assembly process of the rubidium atomic clock is simplified and the assembly efficiency is improved.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
