Description

Technical Field

[0001] This utility model relates to the field of quartz crystal oscillator technology, and in particular to a high-frequency quartz crystal oscillator. Background Technology

[0002] A quartz resonator is a device that utilizes the principle that the crystal resonates due to the piezoelectric effect when the frequency of an electrical signal equals the natural frequency of the quartz crystal. It is a key component in crystal oscillators and narrowband filters. The crystal oscillator casing is usually marked with ink printing to distinguish the crystal type, model, resonant frequency, brand trademark, and production batch.

[0003] However, in the actual use of quartz crystal oscillators, the ink adhesion of traditional screen printing is relatively weak. Furthermore, the sliding friction generated when the tungsten carbide nozzle of the SMT pick-and-place machine picks up the crystal and moves laterally, as well as the contact between the metal tweezers used to hold the crystal and the parameter marking area of ​​the concave shell during manual installation and debugging, can cause the parameter markings to be easily rubbed off, detached, or blurred. Consequently, it becomes impossible for personnel to accurately determine the specific parameters of the crystal oscillator through the parameter markings. Utility Model Content

[0004] Therefore, it is necessary to provide a high-frequency quartz crystal oscillator to address the problem that the surface parameter markings of traditional crystal oscillators are easily worn away during processing, affecting personnel's ability to identify oscillator parameters.

[0005] A high-frequency quartz crystal oscillator includes: an oscillator base and an oscillator housing disposed thereon, wherein a parameter marking body is provided on the surface of the oscillator housing;

[0006] A protective component is disposed on the surface of the oscillator housing and is capable of protecting the parameter label body;

[0007] The protection component includes a port on the surface of the oscillator housing, through which the oscillator housing is disposed, and the parameter identification body is located on the inner wall of the concave shell.

[0008] In one embodiment, the protective component further includes an outer edge portion disposed on the side of the opening located inside the oscillator housing. The surface of the oscillator housing is in contact with the inner wall of the outer edge portion. Through the design of the outer edge portion, the material of the outer edge portion is the same as that of the oscillator housing and the outer edge portion is an integral design with the oscillator housing. The setting of the oscillator housing can increase the insertion depth of the concave shell, so that the parameter label body has sufficient distance to reduce external contact and wear, thereby improving the protection effect of the parameter label body.

[0009] In one embodiment, the inner wall of the outer edge is provided with a slot, and a locking strip located on the surface of the oscillator housing is embedded in the slot. When personnel need to remove the inner concave shell, they only need to use a tool to penetrate into the oscillator housing, then put one end of the tool against the inner concave shell, and apply force to squeeze the locking strip of the inner concave shell out of the slot.

[0010] In one embodiment, the clip is made of rubber, and the overall length of the clip is greater than the diameter of the oscillator housing.

[0011] In one embodiment, the front end face of the oscillator housing is on the same vertical plane as the oscillator housing. Through the above design, it can be ensured that the surface of the oscillator can maintain an absolutely horizontal plane during installation or processing to increase the contact area with the processing instrument.

[0012] In one embodiment, the parameter identifier body is placed in the oscillator housing at the same depth as the outer edge.

[0013] In one embodiment, the four corners inside the oscillator housing are all chamfered. By setting the chamfers, which are arc-shaped chamfers, when the oscillator is compressed or damaged, the four arc-shaped chamfers of the oscillator housing can evenly disperse the impact force, preventing stress concentration and deformation of the parameter label body, so that subsequent personnel can check the parameter label body to know the oscillator parameters during maintenance.

[0014] In one embodiment, a docking seat that plugs into the oscillator housing is provided above the base.

[0015] Beneficial effects

[0016] 1. By placing the parameter marking body on the surface of the oscillator on the inner wall of the concave shell in the protective assembly, the surface of the parameter marking body can be lower than the plane of the concave shell, avoiding direct contact between the parameter marking body and tools, wire harnesses, etc. during processing; at the same time, the rounded chamfer on the inner corner of the concave shell can also make it easier to prevent stress concentration when the oscillator is subjected to impact, which can not only improve the overall strength of the concave shell, but also ensure the protective effect of the concave shell on the parameter marking body.

[0017] 2. By designing the concave shell and the internal parameter marking body as a modular design, the processing steps and procedures during the oscillator shell manufacturing can be reduced. At the same time, it is convenient for personnel to remove and transfer the same type of parameter marking body during subsequent maintenance of the oscillator, which not only saves costs but also improves the adaptability of the product.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is combined with Figure 1 - Figure 5 This invention describes a high-frequency quartz crystal oscillator.

[0028] In one embodiment, a high-frequency quartz crystal oscillator includes: an oscillator base 2 and an oscillator housing 1 disposed thereon, wherein a parameter marking body 5 is disposed on the surface of the oscillator housing 1;

[0029] Protection component 4 is disposed on the surface of oscillator housing 1 and can protect parameter label body 5;

[0030] like Figure 2 and Figure 4 As shown, the protection component 4 includes a through-hole 401 on the surface of the oscillator housing 1, in which the oscillator housing 1 is disposed, and the parameter label body 5 is located on the inner wall of the concave shell 402; the protection component 4 also includes an outer edge portion 404 disposed on the side of the through-hole 401 located inside the oscillator housing 1, and the surface of the oscillator housing 1 is in a fitted state with the inner wall of the outer edge portion 404; the parameter label body 5 is placed in the oscillator housing 1 at the same depth as the outer edge portion 404;

[0031] By placing the parameter identifier body 5 inside the concave shell 402, it is possible to avoid sliding friction when the crystal oscillator is picked up by the tungsten carbide nozzle during processing and avoid contact when the metal tweezers are used to hold the crystal oscillator during manual installation and debugging.

[0032] like Figure 4 and Figure 5 As shown, a slot 405 is provided on the inner wall of the outer edge 404, and a retaining strip 403 located on the surface of the oscillator housing 1 is embedded in the slot 405; the retaining strip 403 is made of rubber, and the overall length of the retaining strip 403 is greater than the diameter of the oscillator housing 1.

[0033] When personnel need to maintain a damaged crystal oscillator, if the previous concave shell 402 is damaged, personnel only need to remove the oscillator housing 1 and parameter label body 5 from the outer edge 404 in the previous concave shell 402 and reinstall them into the new oscillator housing 1. There is no need to replace the whole thing, which not only saves costs but also improves the adaptability of the product.

[0034] In specific operation, simply align the outer edge of the concave shell 402 with the through-hole 401, and then insert the concave shell 402 axially into the through-hole 401. When the concave shell 402 enters the outer edge 404, the retaining strip 403 on its surface will be squeezed and deformed until the retaining strip 403 enters the retaining groove 405. The concave shell 402 is then installed, and the parameter label body 5 will complete the replacement operation.

[0035] The front end face of the oscillator housing 1 is on the same vertical plane as the oscillator housing 1;

[0036] Through the above design, when the tungsten carbide nozzle of the SMT pick-and-place machine picks up the oscillator, the surface of the oscillator housing 1 can be kept absolutely horizontal to increase the contact area with the processing equipment.

[0037] like Figure 4 and Figure 5As shown, all four corners inside the oscillator housing 1 are chamfered.

[0038] Setting an arc-shaped chamfer at the inner corner of the concave shell 402 can prevent stress concentration when the oscillator is impacted. This not only improves the overall strength of the concave shell 402, but also ensures the protective effect of the concave shell 402 on the parameter marking body 5.

[0039] A docking seat 3 is provided above the base 2 and is inserted into the oscillator housing 1;

[0040] The specific working principle of a quartz crystal oscillator is as follows: when a voltage is applied to the electrodes of the quartz crystal, the crystal will start to vibrate, generating mechanical oscillation. This mechanical oscillation is converted into an electrical signal through a feedback circuit and continuously excites the crystal to vibrate, forming a stable oscillation signal.

[0041] The aforementioned method of opening a through-hole 401 on the surface of the oscillator housing 1 of the quartz crystal oscillator and embedding the oscillator housing 1 in the through-hole 401 is explained as follows: Although the aforementioned concave shell 402 is said to be set deep into the oscillator housing 1, the depth of the concave shell 402 is less than the wall thickness of the oscillator housing 1. The crystal is fixed to the center of the inner cavity by cantilever or adhesive, and there is no rigid connection between it and the concave shell 402. Vibration tests show that the local slotting of the concave shell 402 has a small impact on the crystal amplitude and should be considered as negligible data. At the same time, rubber strips 403 and slots 405 are designed on the edge of the concave shell 402 to cooperate and connect, which can not only ensure the overall structural strength of the oscillator housing 1, but also ensure the internal airtightness and shielding continuity of the oscillator housing 1.

[0042] It should be noted that the parameter marking body 5 is set in the concave shell 402. The setting method is not limited to ink printing. For different usage scenarios, laser engraving or relief design can also be used to improve the strength of the parameter marking body 5.

[0043] Working principle: By placing the parameter label body 5 inside the concave shell 402, sliding friction can be avoided when the crystal oscillator is moved laterally during processing with the tungsten carbide pick-up nozzle, as well as contact when the crystal oscillator is manually installed and adjusted using metal tweezers. In addition, when personnel need to maintain a damaged crystal oscillator, if the previous concave shell 402 is damaged, personnel only need to remove the oscillator housing 1 and parameter label body 5 from the outer edge 404 in the previous concave shell 402 and reinstall them into the new oscillator housing 1. There is no need to replace the whole thing, which not only saves costs but also improves the adaptability of the product.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
