Description

Technical Field

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

[0002] In the rapid development of modern electronic technology, quartz crystal oscillators, as key frequency control components, are widely used in many fields such as communications, consumer electronics, medical, and aerospace. Their role is to provide a stable and accurate frequency reference for various electronic devices, acting like a "pacemaker" to ensure the normal operation of the devices and the accurate transmission of signals.

[0003] Existing quartz crystal oscillators often use traditional adhesive bonding to connect the outer casing and the base plate. After the adhesive cures, the bonding strength is strong. When internal components fail and need to be repaired or replaced, it is difficult to insert conventional screwdrivers and tweezers into the gap between the outer casing and the base plate to achieve non-destructive separation. When the outer casing is disassembled, the plastic casing is prone to local breakage, which damages the structural integrity and causes the internal components to shift, affecting the operation of the equipment. Therefore, improvements are needed to address these issues. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example: See Figure 1-6 This utility model discloses a quartz crystal oscillator, comprising a housing 1, a base plate 2 on the bottom surface of the housing 1, a fixed connection assembly between the housing 1 and the base plate 2, a crystal oscillator chip 7 in the center of the top surface of the base plate 2, four first rotating shafts 6 arranged in a rectangular pattern around the crystal oscillator chip 7, a corner of a triangular fixing block 8 rotatably mounted on the first rotating shafts 6, and multiple pins 4 connected to the bottom surface of the crystal oscillator chip 7, with the bottom ends of the pins 4 penetrating the bottom surface of the base plate 2. This structure, through a specific layout, lays the foundation for the subsequent installation and coordinated operation of various components, improving the regularity and stability of the overall structure; chamfers are provided at all four corners of the crystal oscillator chip 7. A fixing plate 12 protrudes from the top surface of the base plate 2 at the chamfer of the crystal oscillator chip 7, and a triangular fixing block 8 rotates and fits against the top surface of the fixing plate 12. This design allows the triangular fixing block 8 to fit better against the crystal oscillator chip 7, enhancing the fixing effect of the crystal oscillator chip 7 and effectively preventing the crystal oscillator chip 7 from shifting during operation. The triangular fixing block 8 and the fixing plate 12 are coaxially provided with a threaded fixing hole 9, and a fixing bolt is screwed into the threaded fixing hole 9. By tightening the bolt, the firmness of the fixation is further improved, ensuring that the connection between the triangular fixing block 8 and the fixing plate 12 is stable under various working conditions, thereby firmly fixing the crystal oscillator chip 7.

[0022] In this invention, the bottom surface of the base plate 2 is provided with multiple fixing screws, which are inserted one by one into the bottom end of the first rotating shaft 6. This increases the stability of the first rotating shaft 6, making the entire crystal oscillator chip 7 fixing structure more robust and better able to withstand harsh environments such as vibration, ensuring the stable operation of the crystal oscillator chip 7. The fixing connection assembly includes multiple rectangular slots opened on the outer walls of both sides of the base plate 2. A rotating plate 3 is provided on the rectangular slot. A second rotating shaft 14 extends from the middle of the top surface of the rotating plate 3. A spring 13 is provided at one end of the rotating plate 3 opposite to the rectangular slot. A protruding post 11 is fixedly connected to the other end of the rotating plate 3 opposite to the rectangular slot. An installation slot 10 is opened on the periphery of the top surface of the base plate 2. A snap-fit ​​block 5 corresponding to the insertion into the installation slot 10 is protruding on the periphery of the bottom surface of the outer shell 1. The snap-fit ​​block 5 has an insertion hole for inserting the protrusion 11; this enables convenient installation and disassembly of the outer shell 1 and the base plate 2 without the need for glue, greatly improving installation efficiency while ensuring the stability of the connection; the protrusion 11 is divided into two sections, one of which has a rotating groove, and the other has a protrusion that inserts into the rotating groove. A third rotating shaft passes through the protrusion 11 between the rotating groove and the protrusion. A hook seat is provided on one side of the rectangular groove of the spring 13, and a corresponding limiting hook is provided on the rotating plate 3; this further optimizes the structure of the rotating plate 3 and the protrusion 11, making them more flexible and reliable during installation and use, and enhancing the stability and durability of the entire fixed connection assembly.

[0023] Working Principle: When using this invention, during the installation of the quartz crystal oscillator, the crystal chip 7 is first placed in the center of the top surface of the base plate 2. The four corners of the crystal chip 7 are pre-chamfered. A fixing plate 12 protrudes from the chamfered corners of the crystal chip 7 on the top surface of the base plate 2. Four first rotating shafts 6 are provided on the base plate 2. One corner of the triangular fixing block 8 is rotatably connected to the base plate 2 via the first rotating shafts 6, causing the triangular fixing block 8 to rotate and fit against the top surface of the fixing plate 12. At this time, the triangular fixing block 8 and the fixing plate 12 are coaxially connected by threaded fixing holes 9. Appropriate fixing bolts are selected and screwed into the threaded fixing holes 9. As the bolts are tightened, the triangular fixing block 8 is firmly fixed to the fixing plate 12, forming a stable clamping effect on the crystal chip 7 from the four corners. Subsequently, operations are performed on the bottom surface of the base plate 2 to insert multiple fixing screws... One by one, the screws are inserted into the bottom of the first rotating shaft 6. These fixing screws further enhance the stability of the first rotating shaft 6 and the entire fixing structure, ensuring that the crystal oscillator chip 7 can be firmly kept in place during the operation of the equipment, even if it is subjected to strong vibration or impact, and ensuring its stable operation. Next, prepare to install the outer casing 1. First, place the base plate 2, on which the crystal oscillator chip 7 has been fixed, on a stable surface. The base plate 2 is provided with a rectangular groove and a rotating plate 3. During installation, press the rotating plate 3 toward the end where the spring 13 is located. Then, align the snap-fit ​​block 5 at the bottom of the outer casing 1 with the mounting groove 10 on the base plate 2 and insert it. After it is inserted into place, release the rotating plate 3. At this time, the spring 13 returns to its original position, driving the protrusion 11 on the rotating plate 3 to insert into the insertion hole of the snap-fit ​​block 5, completing the quick installation and fixing of the outer casing 1 and the base plate 2. At this point, the device is ready for use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
