Description

Technical Field

[0002] In precision electronic devices such as communication base stations and navigation systems, crystal oscillators serve as the core clock source, and their frequency stability directly determines system performance. However, traditional crystal oscillators are susceptible to environmental temperature fluctuations, external magnetic field interference, and mechanical stress, leading to frequency drift, increased phase noise, and decreased long-term reliability.

[0003] Existing timekeeping terminal devices employ conventional design and manufacturing processes. The terminal casing is made of aluminum alloy with a conductive anodizing treatment. However, the casing lacks dedicated magnetic shielding measures for areas with large openings, such as the display screen, silicone buttons, and connectors. The processing module housing the core timekeeping function's crystal oscillator circuit is also made of aluminum alloy with a conductive anodizing treatment. Furthermore, the processing module lacks specific temperature protection measures.

[0004] Existing timekeeping terminal devices use conventional designs for magnetic shielding and temperature protection, without dedicated temperature protection measures. This makes the internal crystal oscillator circuit of the terminal susceptible to interference from external magnetic fields and ambient temperature fluctuations, thus affecting the timekeeping accuracy of the terminal.

[0044] refer to Figures 1-11 This embodiment provides a timekeeping terminal device, which aims to strengthen magnetic shielding and temperature protection from a structural perspective, so that the internal crystal oscillator circuit is not affected by external magnetic fields and ambient temperature fluctuations, significantly improving the frequency stability and reliability of the crystal oscillator circuit in complex environments, and achieving the purpose of high-precision timekeeping.

[0045] like Figure 1 The timekeeping terminal device in this embodiment includes a housing assembly 1, a comprehensive board assembly 4, a battery assembly 5, a processing module 2, and an aviation plug assembly 3. Wherein:

[0046] In this embodiment, the outer casing assembly 1 includes a mounting cavity, and the integrated board assembly 4, battery assembly 5, and processing module 2 are placed in the mounting cavity (e.g., ...). Figure 2 The outer casing assembly 1 includes an upper cover housing 11 and a lower cover housing 12. Both the upper cover housing 11 and the lower cover housing 12 are milled from magnesium alloy. The surfaces of both the upper cover housing 11 and the lower cover housing 12 are treated with nickel plating to enhance their conductivity and improve the magnetic shielding performance of the terminal casing.

[0047] like Figure 4 The viewing area 111 of the upper cover housing 11 is provided with shielding glass 13. Shielding glass 13 is a special type of glass in which a low-resistance metal mesh is laminated between two layers of glass. The shielding glass 13 is connected to the upper cover housing 11 by conductive adhesive, which bonds the shielding glass 13 to the upper cover housing 11, making the shielding glass 13 and the upper cover housing 11 electrically continuous and forming a shielding whole. This compensates for shielding gaps in the display area and further improves the magnetic shielding performance.

[0048] like Figure 6The button area 112 of the upper cover housing 11 is provided with silicone buttons 14, and a button pressure plate 15 is provided below the silicone buttons 14; a shielding metal mesh 16 is provided between the silicone buttons 14 and the button pressure plate 15. The shielding metal mesh 16 is pressed against the inner wall of the upper cover housing 11 by the button pressure plate 15, so that the shielding metal mesh 16 and the upper cover housing 11 are electrically continuous, making the entire upper cover housing 11 a complete shield. Magnetic fields cannot enter the device through the silicone buttons 14 area, thus compensating for the shielding gaps of the silicone buttons 14, forming a shielding whole, and improving the magnetic shielding performance.

[0049] A shielding rubber strip 17 is provided on the mating surface of the upper cover housing 11 and the lower cover housing 12. The shielding rubber strip 17 is a D-type shielding rubber strip 17. Figure 5 Specifically, the mating surface of the upper cover housing 11 is provided with a placement groove 113, and the shielding rubber strip 17 is disposed in the placement groove 113. When the upper cover housing 11 and the lower cover housing 12 are pressed together, the shielding rubber strip 17 is fixed in the placement groove 113 under the pressure of the upper cover housing 11. By providing the shielding rubber strip 17, the magnetic field leakage problem caused by unevenness or small gaps at the mating surface of the housing 21 and the lower cover housing 12 is avoided, so that the mating surface of the upper cover housing 11 and the lower cover housing 12 has good electrical contact and electrical continuity, thereby improving the magnetic shielding performance.

[0050] like Figure 2 The upper cover housing 11 and the lower cover housing 12 are fixedly connected by a plurality of mounting screws 18, the mounting spacing of the plurality of mounting screws 18 being ≤40mm. By reasonably distributing the spacing of the mounting screws 18 between the upper and lower cover housings 12, sufficient mechanical strength and tightness can be ensured at the joint surface of the upper cover housing 11 and the lower cover housing 12. The tightening effect of the mounting screws 18 allows the shielding rubber strip 17 to be uniformly compressed between the joint surfaces, thereby ensuring a stable electrical contact between the shielding rubber strip 17 and the upper cover housing 11 and the lower cover housing 12.

[0051] In this embodiment, the aircraft insertion assembly 3 is disposed on one side of the outer shell assembly 1 (e.g., Figure 4 ), and passes through the housing assembly 1 and connects to the integrated plate assembly 4. For example Figure 7 The aerospace connector assembly 3 includes a printed circuit board 32 and three shielded connectors 31. The three shielded connectors 31 are soldered onto a rigid-flex printed circuit board 32. A flexible circuit board 33 extends from the printed circuit board 32 and is connected to the integrated board 41 through the flexible circuit board 33. The connectors are shielded connectors 31 to improve the overall magnetic shielding performance.

[0052] The integrated board assembly 4 described in this embodiment includes an integrated board 41 and a display screen 42 (e.g., ...). Figure 8 The display screen 42 is installed below the viewing area 111 of the upper cover housing 11. Pins 43 are provided on the display screen 42, and holes 44 are provided on the integrated plate 41. The display screen 42 is connected to the integrated plate 41 through the insertion of the pins 43 into the holes 44. The battery assembly 5 in this embodiment includes a battery 51 and a battery frame 52 for mounting the battery 51 (e.g., ...). Figure 9 ).

[0053] The processing module 2 described in this embodiment includes a housing 21 and a processing board 22 disposed inside the housing 21. The processing board 22 is provided with a core crystal oscillator circuit for timekeeping function. The housing 21 is filled with aerogel insulation cotton 23, and the processing board 22 is wrapped by the aerogel insulation cotton 23 (e.g., Figure 11 Aerogel insulation cotton 23 is used to fill the top, bottom and sides of the processing board 22. Aerogel insulation cotton 23 is a new type of insulation material with a thermal conductivity as low as 0.016W / mk. It can effectively reduce the rapid transfer of temperature, so that the crystal oscillator circuit can work in a relatively stable temperature environment and avoid interference from rapid changes in external temperature.

[0054] like Figure 10 The housing 21 includes a shielded cavity 211 and a shielded cavity cover 222. The cavity cover 222 is provided with a wiring channel 223 for the FPC 24 wiring of the processing board 22. The processing board 22 is connected to the integrated board 41 through the FPC 24. Both the cavity 211 and the cavity cover 222 are made of nickel alloy material. Nickel alloy material has high magnetic permeability and can effectively absorb and shield magnetic fields, so that the crystal oscillator circuit operates in a relatively stable magnetic field environment and avoids interference from external magnetic fields.

[0055] This embodiment provides a timekeeping terminal device that employs a temperature-insulated, constant-magnetic cavity 211. Through interdisciplinary technology integration and innovative structural design, it significantly improves the frequency stability and reliability of the crystal oscillator circuit in complex environments. The magnetic shielding measures are more comprehensive, providing stronger protection; the use of aerogel insulation cotton 23 adds dedicated temperature protection measures, providing the constant-temperature environment required by the crystal oscillator circuit.

[0056] This embodiment provides a timekeeping terminal device. Through structural design, the magnetic shielding and temperature protection capabilities of the terminal are improved, avoiding interference from external magnetic fields and ambient temperature fluctuations to the crystal oscillator circuit of the internal processing board 22. This significantly improves the frequency stability and reliability of the crystal oscillator circuit in complex environments, thereby achieving high-precision timekeeping performance of the terminal.

[0057] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
