An integrated quartz crystal oscillator packaging assembly

Abstract

This utility model provides an integrated quartz crystal oscillator packaging assembly, relating to the field of oscillator technology. It includes a base, an impact-resistant shell on top of the base, an outer sealing edge for the impact-resistant shell, and a metal shell inside the impact-resistant shell. The outer surface of the metal shell has a first protrusion arranged in a vertical array around its circumference. A silicone ring is arranged in a vertical array between the metal shell and the impact-resistant shell. A silicone ring and a silicone pad are also provided between the impact-resistant shell and the metal shell. This design allows the impact-resistant shell to initially resist the impact source upon impact. The gap between the impact-resistant shell and the fixed shell, combined with the silicone ring and silicone pad, forms a compressible buffer space. When the impact-resistant shell is displaced by an impact, the silicone ring is compressed, and its elastic reaction force offsets part of the impact force. Simultaneously, the gap allows for small displacement of the shell, preventing rigid collisions. This improves the overall strength and solves the problem of limited protective strength in single-shell packaging structures.

Description

Technical Field

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

[0002] According to the shock-resistant structure for a quartz crystal oscillator disclosed in Chinese Publication No. CN2884640U, it includes a main body shell and a cover plate. The cover plate and the main body shell are detachably connected by screws to form a mounting cavity. A connecting base is disposed within the mounting cavity, and multiple sets of buffer components are disposed between the connecting base and the main body shell. The crystal body is mounted within the connecting base, and multiple sets of spring contacts are disposed within the connecting base, located between the connecting base and the crystal body and in contact with the crystal body. A fixing plate is detachably disposed on the connecting base, and the crystal body is held between the fixing plate and the connecting base. This shock-resistant structure, through the mounting cavity formed by the cover plate and the main body shell, and the crystal body mounted on the connecting base and located within the mounting cavity, can prevent the direct action of external collision forces on the crystal body. The multiple sets of buffer components disposed between the connecting base and the main body shell can effectively absorb and disperse impact forces, reducing the possibility of damage to the crystal body.

[0003] In existing technologies, quartz crystal oscillators are generally packaged using a single-layer metal shell structure. This shell is typically formed in one piece through processes such as stamping or injection molding, creating a sealed cavity inside to provide basic airtightness, dustproofing, and mechanical protection. However, with the diversification of application scenarios and the increase in extreme environments, the protective strength of existing single-shell packaging structures is limited. Due to the use of a single-layer thin-walled metal material, its wall strength is low, making it difficult to effectively resist strong mechanical shocks, vibrations, or drop impacts, which can easily lead to damage to the internal crystal or circuit failure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the limited protective strength of the single-shell packaging structure in the prior art, and to propose an integrated quartz crystal oscillator packaging component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated quartz crystal oscillator packaging assembly, comprising a base, an impact-resistant shell on the top of the base, an outer sealing edge on the outside of the impact-resistant shell, a metal shell inside the impact-resistant shell, a first protrusion arranged in a vertical array around the outer surface of the metal shell, a silicone ring arranged in a vertical array between the metal shell and the impact-resistant shell, a folded edge on the bottom outer surface of the impact-resistant shell, a second protrusion on the top surface of the metal shell, a silicone pad on the top of the metal shell, a connecting seat inside the metal shell, a quartz crystal oscillator body on the top of the connecting seat, four pins on the bottom surface of the quartz crystal oscillator body, and grooves on the inner surfaces of the silicone ring and the silicone pad.

[0006] Preferably, the connector is welded to the top surface of the base, and the quartz crystal oscillator body is welded to the top surface of the connector.

[0007] Preferably, the four pins are located at each corner of the bottom surface of the quartz crystal oscillator body, the bottom ends of the four pins penetrate the base, and the top surfaces of the pins are welded to the quartz crystal oscillator body.

[0008] Preferably, the metal casing is mounted on the top surface of the base, and the metal casing is welded to the base.

[0009] Preferably, the first and second protrusions on the outer surface of the metal shell are integrally formed with the metal shell, and the impact-resistant shell is integrally formed with the bottom edge.

[0010] Preferably, the silicone ring is sleeved with the metal shell, and the silicone pad is installed on the top surface of the metal shell. The position of the groove on the inner surface of the silicone ring corresponds one-to-one with the position of the first protrusion on the outer surface of the metal shell, and the position of the groove on the bottom surface of the silicone pad corresponds one-to-one with the position of the second protrusion on the top surface of the metal shell. The first protrusion is installed in the groove on the inner surface of the silicone ring, and the second protrusion is installed in the groove on the bottom surface of the silicone pad.

[0011] Preferably, the impact-resistant outer shell is installed on the top surface of the base by sealing the edges, and the sealing edges are welded to the base.

[0012] Beneficial effects In this invention, an impact-resistant outer shell is added to the outside of the existing metal outer shell. The impact-resistant outer shell is fixed to the base by sealing the bottom folded edge, and a gap is reserved on the bottom surface of the sealing edge to allow the bottom folded edge of the impact-resistant outer shell to move slightly when impacted. A silicone ring and silicone pad are also provided between the impact-resistant outer shell and the metal outer shell. When subjected to external impact, the impact-resistant outer shell first blocks the impact source. Due to the gap between the impact-resistant outer shell and the fixed outer shell, together with the silicone ring and silicone pad, a compressible buffer space is formed. When the impact-resistant outer shell is displaced by impact, the silicone ring is compressed, and its elastic reaction force will offset part of the impact force. At the same time, the gap allows the shell to move slightly, avoiding rigid collisions. This improves the overall strength and solves the problem of limited protective strength of single-shell encapsulation structures. Attached Figure Description

[0015] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1: Reference Figure 1-6An integrated quartz crystal oscillator packaging assembly includes a base 1, an impact-resistant shell 3 on the top of the base 1, a sealing edge 2 on the outside of the impact-resistant shell 3, a metal shell 4 inside the impact-resistant shell 3, a first protrusion 9 arranged in a vertical array around the outer surface of the metal shell 4, a silicone ring 10 arranged in a vertical array between the metal shell 4 and the impact-resistant shell 3, a folded edge 8 on the bottom outer surface of the impact-resistant shell 3, a second protrusion 11 on the top surface of the metal shell 4, a silicone pad 12 on the top of the metal shell 4, a connecting seat 5 inside the metal shell 4, a quartz crystal oscillator body 6 on the top of the connecting seat 5, four pins 7 on the bottom surface of the quartz crystal oscillator body 6, grooves 13 on the inner surfaces of the silicone ring 10 and the silicone pad 12, the connecting seat 5 being welded to the top surface of the base 1, and the quartz crystal oscillator body 6 being welded to the top surface of the connecting seat 5, with the four pins 7 located at various corners of the bottom surface of the quartz crystal oscillator body 6. The bottom ends of the four pins 7 all penetrate the base 1, and the top surface of the pins 7 is welded to the main body 6 of the quartz crystal oscillator. The metal shell 4 is installed on the top surface of the base 1 and is welded to the base 1. The first protrusion 9 and the second protrusion 11 on the outer surface of the metal shell 4 are integrally formed with the metal shell 4. The impact-resistant shell 3 is integrally formed with the bottom edge 8. The silicone ring 10 is sleeved with the metal shell 4, and the silicone pad 12 is installed on the top surface of the metal shell 4. The position of the groove 13 on the inner surface of the silicone ring 10 corresponds one-to-one with the position of the first protrusion 9 on the outer surface of the metal shell 4. The position of the groove 13 on the bottom surface of the silicone pad 12 corresponds one-to-one with the position of the second protrusion 11 on the top surface of the metal shell 4. The first protrusion 9 is installed in the groove 13 on the inner surface of the silicone ring 10, and the second protrusion 11 is installed in the groove 13 on the bottom surface of the silicone pad 12. The impact-resistant shell 3 is installed on the top surface of the base 1 through the sealing edge 2 and is welded to the base 1.

[0018] The base 1 serves as the foundation and support structure for the entire encapsulation assembly, providing a stable mounting platform. The shock-resistant housing 3 is the first line of shock resistance for the assembly. When an external impact occurs, the shock-resistant housing 3 first comes into contact with the impact source, absorbing and resisting most of the impact force. It is integrally formed with the bottom folded edge 8 and mounted on the base 1 via the sealing edge 2. The folded edge 8 is part of the outer surface of the bottom end of the shock-resistant housing 3 and is integrally formed with it. It cooperates with the sealing edge 2 and the base 1 to form a movable fixed structure. When the shock-resistant housing 3 is impacted, the folded edge 8 moves slightly within the gap reserved in the sealing edge 2, allowing the shock-resistant housing 3 to cushion the impact. The sealing edge 2 is used to fix the shock-resistant housing 3 to the base 1. It achieves fixation by pressing down on the folded edge 8 at the bottom end of the shock-resistant housing 3 and is welded to the base 1. At the same time, the movable gap reserved in the folded design allows the shock-resistant housing 3 to have a certain amount of cushioning and movement space when impacted, thereby avoiding the direct transmission of impact force caused by rigid connection. The metal casing 4 is the second layer of impact-resistant structure, directly encasing the connector 5 and the quartz crystal oscillator body 6. It is welded to the base 1, providing robust internal support and electromagnetic shielding. Its outer surface has a first protrusion 9 and a second protrusion 11 on the top surface. These protrusions precisely engage with grooves 13 on the silicone ring 10 and silicone pad 12. These provide limiting and locking, ensuring that the silicone cushioning elements are effectively compressed under stress, rather than detaching from the encased metal casing 4. The silicone ring 10 and silicone pad 12 function as the cushioning elements of the entire impact-resistant mechanism. They utilize the elasticity and compressibility of the silicone material to absorb and disperse impact energy. The silicone ring 10 is installed between the metal casing 4 and the impact-resistant casing 3. When the impact-resistant casing 3 is impacted and moves inward, the silicone ring 10 is radially compressed, and its elastic reaction force offsets part of the impact force and limits the lateral displacement of the metal casing 4. The silicone pad 12 is installed on top of the metal casing 4. When the impact-resistant casing 3 is impacted vertically, the silicone pad 12 is axially compressed, providing vertical cushioning. The engagement of the groove 13 and the bump ensures that the silicone can be effectively and evenly compressed upon impact, maximizing its cushioning effect. The connector 5 is the connecting frame between the quartz crystal oscillator body 6 and the base 1. It is welded to the top surface of the base 1 and serves as the mounting platform for the quartz crystal oscillator body 6, ensuring the stability and electrical connection of the quartz crystal oscillator within its internal package. The quartz crystal oscillator body 6 is the core functional component of the entire assembly. It utilizes the piezoelectric effect of the quartz crystal to generate a stable and precise oscillation frequency, making it a key component providing clock signals in electronic devices. Its working principle is based on the resonance generated by the quartz crystal under the influence of an alternating electric field. Pins 7 are the interface for electrical connection between the quartz crystal oscillator body 6 and external circuits. They pass through the base 1, transmitting the frequency signal generated by the quartz crystal oscillator to external devices and receiving power signals, etc. The welding of pins 7 ensures the reliability of signal transmission. Specific Implementation Example 2: reference Figure 1-6The integrated quartz crystal oscillator packaging assembly, further based on the basic structure in Specific Embodiment 1, allows the quartz crystal oscillator body 6 to be securely welded to the top of the base 1 via the connecting seat 5 during daily use without external impact. The pins 7 penetrate the base 1 and connect to external circuitry to complete clock signal input and output. The metal casing 4 is fixed to the base 1 by welding, forming a sealed space inside to provide mechanical protection and electromagnetic shielding, preventing external electromagnetic interference from affecting the oscillator's accuracy. The outer surface of the metal casing 4 has a first protrusion 9, and the top surface has a second protrusion 11. These protrusions precisely correspond to and cooperate with the grooves 13 on the silicone ring 10 and silicone pad 12, forming a stable and reliable assembly positioning relationship. The impact-resistant casing 3, through its integrally formed folded edge 8 at the bottom, cooperates with the gapped sealing edge 2 and the base 1, and is flexibly fixed by welding. In this state, the internal quartz crystal resonator operates normally, outputting a stable oscillation frequency, all structures remain stable, and all buffer components are in a natural, uncompressed state. When the equipment is subjected to external impact, the impact force first acts on the outermost impact-resistant shell 3, which has good strength and toughness and can absorb part of the impact energy. The impact-resistant shell 3 forms a micro-movement space through the gap reserved between the bottom folded edge 8 and the sealing edge 2. When impacted, the impact-resistant shell 3 can move slightly within a limited range, effectively preventing the direct transmission of rigid collisions. When the impact-resistant shell 3 shifts, the silicone ring 10 located between its inner side and the metal shell 4 and the top silicone pad 12 will be compressed. The silicone ring 10 is compressed by radial pressure, and the silicone pad 12 is compressed by axial pressure. Through the good elasticity and compressibility of the silicone material, the two form an elastic reaction force, gradually dissipating the impact energy and preventing the impact force from being directly transmitted to the metal shell 4. At the same time, the grooves 13 on the inner surfaces of the silicone ring 10 and the silicone pad 12 precisely match the first protrusion 9 and the second protrusion 11 on the metal shell 4, which can effectively limit and prevent detachment under impact, ensuring that the buffer structure does not shift or misalign under force. If the impact force is large enough to reach the limits of the impact-resistant outer shell 3 and the silicone cushioning system, the metal outer shell 4, acting as a second layer of rigid protective housing, will continue to provide mechanical protection and support, preventing damage to the internal connector 5 and the quartz crystal oscillator body 6. The metal outer shell 4 is welded to the base 1 to form a closed space, ensuring the structural safety of the internal components. Through the welding fixation between the connector 5 and the base 1, the quartz crystal oscillator body 6 is firmly and stably secured, maintaining its position and preventing pin 7 from detaching even after multiple layers of cushioning and protection, ensuring normal function. The four pins 7 of the quartz crystal oscillator body 6 are connected to the outside through vias on the base 1, enabling frequency signal output and power supply. The pins 7 are firmly welded to the crystal body, ensuring reliable electrical performance and preventing cold solder joints and signal loss under vibration.The micro-gap design between the impact-resistant outer shell 3 and the metal outer shell 4 not only provides impact buffer space but also forms a micro-air layer, which serves as a certain heat insulation and heat dissipation channel, helping to conduct the heat generated during the operation of the quartz oscillator to the outer shell for dissipation. The metal outer shell 4 is sealed to the silicone component through the first protrusion 9 and the second protrusion 11, forming a good seal while providing support for the heat conduction path.

[0020] In summary: 1. An impact-resistant outer shell 3 is provided outside the existing metal outer shell 4. The impact-resistant outer shell 3 is fixed to the base 1 by pressing the bottom folded edge 8 with the sealing edge 2, and a gap is reserved on the bottom surface of the sealing edge 2 to allow the bottom folded edge 8 of the impact-resistant outer shell 3 to move slightly when impacted. A silicone ring 10 and a silicone pad 12 are provided between the impact-resistant outer shell 3 and the metal outer shell 4. When subjected to external impact, the impact-resistant outer shell 3 first resists the impact source. Due to the gap between the impact-resistant outer shell 3 and the fixed shell, the silicone ring 10 and silicone pad 12 form a compressible buffer space. When the impact-resistant outer shell 3 is displaced by impact, the silicone ring 10 is compressed, and its elastic reaction force will offset part of the impact force. At the same time, the gap allows the shell to move slightly, avoiding rigid collisions. This improves the overall strength and solves the problem of limited protection strength of single-shell encapsulation structures.
