When it comes to frequency changes, the accuracy needs to reach 1ppb or even higher. Through experiments, it has been found that adding a heat insulation structure to the outside of the crystal can greatly improve its temperature characteristics and frequency stability.

[0003] Existing crystal insulation structural components are complex in structure, inconvenient to use, and have poor protective effect. They are also prone to damage during long-term use. Utility Model Content

[0004] The purpose of this utility model is to provide a crystal thermal insulation structural component to solve the defect that the existing crystal thermal insulation structural component has a relatively complex structure.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a crystal heat insulation structure, including a base, a hollow groove on the base, a solder paste soldering groove on the outer side of the hollow groove, a first connecting groove on the outer side of the base, a heat insulation cover on the top of the base, a second connecting groove on the heat insulation cover, and a protective layer on the surface of both the base and the heat insulation cover.

[0006] Preferably, the base has a square hole on its side.

[0007] The above structure is used for crystal orientation.

[0008] Preferably, the first connecting groove has a recess, and the second connecting groove has a sealing gasket installed on it.

[0009] The above structure enhances the seal between the base and the insulation cover.

[0010] Preferably, a positioning structure is provided between the base and the heat preservation cover. The positioning structure includes a slot, a positioning groove and a positioning block. The positioning block is evenly installed on the second connecting groove inside the sealing gasket. The positioning groove is evenly opened on the first connecting groove inside the groove. One end of each positioning groove is provided with a slot.

[0011] The above structure enhances the stability of the connection between the base and the insulation cover.

[0012] Preferably, the width of the positioning block is smaller than the width of the positioning groove, and the positioning block and the positioning groove form a sliding structure.

[0013] With the above structure, by rotating the heat insulation cover, the positioning block can slide into the slot along the direction of the positioning groove.

[0014] Preferably, the positioning block cooperates with the slot, and the positioning block and the slot form an engaging structure.

[0015] Through the above structure, the positioning block and the slot can play a certain positioning role for the heat insulation cover.

[0016] Preferably, the protective layer is a nano-coating.

[0017] The above structure provides some protection for the base and the insulation cover.

[0018] The advantages of the crystal thermal insulation structural component provided by this utility model are as follows:

[0019] By adding a base and cover to the crystal for heat preservation, the product's temperature characteristics, frequency stability, phase noise, etc., are improved, resulting in better performance indicators for the product.

[0020] Furthermore, a protective layer is applied to the surface of the base and the insulation cover. This protective layer can provide a certain degree of protection for the base and the insulation cover, enhance their wear resistance, corrosion resistance, high temperature resistance and anti-fouling performance, and improve their performance.

[0021] With the positioning structure in place, when the base is connected to the insulation cover, the positioning block is inserted into the positioning groove. When the insulation cover is rotated, the positioning block slides along the direction of the positioning groove until it enters the slot and engages with it. The engagement of the positioning block and the slot enhances the stability of the connection between the base and the insulation cover.

[0022] With the addition of a sealing gasket, when the base is connected to the insulation cover, the gasket snaps into the groove, providing a certain degree of sealing and enhancing the airtightness between the base and the insulation cover, thereby improving the waterproof and dustproof functions of the insulation structure.

A solder paste soldering groove 3 is provided on the base 1 outside the hollow groove 4. A first connecting groove 2 is provided on the base 1 outside the solder paste soldering groove 3. A heat insulation cover 6 is provided at the top of the base 1. A second connecting groove 7 is provided on the heat insulation cover 6. A protective layer 9 is provided on the surface of both the base 1 and the heat insulation cover 6. The protective layer 9 is a nano-coating.

[0032] Solder paste is applied to the solder paste soldering tank 3. The crystal is then passed through the hollow part of the hollow tank 4, with its edges secured within the solder paste soldering tank 3. A hot air gun is used to cure the solder paste at high temperature, thus fixing the crystal in place. Finally, a soldering iron is used to fix the second connecting groove 7 of the insulation cover 6 to the first connecting groove 2 of the base 1, forming a complete insulation structure. This insulation structure improves the crystal's temperature characteristics, frequency stability, and phase noise, resulting in better performance across the crystal's various parameters. The protective layer 9 provides some protection for the base 1 and the insulation cover 6, enhancing their wear resistance, corrosion resistance, high temperature resistance, and anti-fouling properties, thereby improving their overall performance.

[0033] Reference Figure 1 and Figure 2 As shown, a groove 21 is provided on the first connecting groove 2, and a sealing gasket 8 is installed on the second connecting groove 7.

[0034] When the base 1 is connected to the insulation cover 6, the sealing gasket 8 is inserted into the groove 21. The sealing gasket 8 can play a certain sealing role, enhance the sealing between the base 1 and the insulation cover 6, and improve the waterproof and dustproof function of the insulation structure.

[0035] Reference Figure 1 and Figure 2 As shown, a positioning structure 5 is provided between the base 1 and the heat preservation cover 6. The positioning structure 5 includes a slot 51, a positioning groove 52 and a positioning block 53. The positioning block 53 is evenly installed on the second connecting groove 7 inside the sealing gasket 8. The positioning groove 52 is evenly opened on the first connecting groove 2 inside the groove 21. The width of the positioning block 53 is smaller than the width of the positioning groove 52. The positioning block 53 and the positioning groove 52 form a sliding structure. A slot 51 is opened at one end of the positioning groove 52. The positioning block 53 cooperates with the slot 51, and the positioning block 53 and the slot 51 form a locking structure.

[0036] When the base 1 is connected to the heat preservation cover 6, the positioning block 53 is inserted into the positioning groove 52. When the heat preservation cover 6 is rotated, the positioning block 53 slides along the direction of the positioning groove 52 until it enters the slot 51 and engages with it. Through the engaging action of the positioning block 53 and the slot 51, the stability of the connection between the base 1 and the heat preservation cover 6 can be enhanced.
