Description

Technical Field

[0001] The utility model relates to the technical field of quartz crystals, in particular to a packaging structure of a quartz crystal. Background Art

[0002] Quartz is one of the main rock-forming minerals, generally referring to low-temperature quartz (α-quartz), which is the most widely distributed mineral in the quartz family. In a broad sense, quartz also includes high-temperature quartz (β-quartz) and coesite. The main component is SiO2, which is colorless and transparent, and often contains a small amount of impurities, turning into translucent or opaque crystals with a hard texture.

[0003] Quartz is a mineral composed of silicon dioxide, with the chemical formula SiO2. Pure quartz is colorless and transparent. It has various colors due to the presence of trace pigment ions or finely dispersed inclusions, or color centers, and its transparency is reduced. It has a glassy luster and a greasy luster on the fracture. It has a hardness of 7, no cleavage, and a shell-like fracture. Its specific gravity is 2.65. It has piezoelectricity.

[0004] It has a wide range of uses. As early as the Stone Age, people used it to make simple production tools such as stone axes and stone arrows to hunt for food and fight against enemies. Piezoelectric quartz sheets are used as standard frequencies in quartz clocks and electronic equipment. The glass made after melting can be used to make optical instruments, glasses, glass tubes and other products. It can also be used as bearings for precision instruments, grinding materials, glass ceramics and other industrial raw materials.

[0005] When currently quartz crystals are packaged, the quartz crystals are placed in a mounting seat, and the mounting seat is sealed by an upper cover, thereby sealing the quartz crystal in the mounting seat. When the upper cover is used to seal the mounting seat, there will be a gap between the upper cover and the mounting seat, which can easily allow external liquid to enter the mounting seat and cause damage to the quartz crystal.

[0029] See also Figures 1-2 : A quartz crystal packaging structure includes a base 1, a quartz crystal 2, a first electrode 3, a second electrode 4, and a sealant. The base 1 is provided with a receiving groove 11, and the quartz crystal 2 is fixedly or detachably installed in the receiving groove 11. The first electrode 3 and the second electrode 4 are respectively fixedly or detachably installed at the two ends of the base 1 and are respectively electrically connected to the two connecting terminals 21 of the quartz crystal 2. The sealant is sealed and installed at the opening of the base 1, and is used to seal and install the quartz crystal 2 in the base 1.

[0030] In one embodiment, the open end of the base 1 has a two-step structure 12, which is used to ensure that the sealant is at the same level as the open end of the base 1 during sealing.

[0031] In one embodiment, a separation block 111 is provided in the receiving groove 11 for separating the first electrode 3 and the second electrode 4 .

[0032] In one embodiment, the bottom surface of the receiving groove 11 is a curved surface or a curved surface structure.

[0033] In one embodiment, the bottom of the base 1 has a first mounting portion 13 for mounting the first electrode 3 .

[0034] In one embodiment, the bottom of the base 1 has a second mounting portion 14 for mounting the second electrode 4 .

[0035] In one embodiment, the second mounting portion 14 defines a first notch 141 .

[0036] In one embodiment, the sealant includes one of a wet air vulcanized sealant, a chemical vulcanized sealant, a silicone sealant, a polyurethane sealant, or a polysulfide sealant.

[0037] In one embodiment, the shape and size of the bottom surface of the accommodating groove 11 are matched with the shape and size of the bottom surface of the quartz crystal 2 .

[0038] A packaging method for a quartz crystal packaging structure,

[0039] A receiving groove 11 is formed on the base 1;

[0040] Placing the quartz crystal 2 in the containing groove 11;

[0041] The two connection terminals 21 of the quartz crystal 2 are electrically connected to the first electrode 3 and the second electrode 4 respectively;

[0042] The quartz crystal 2 is packaged in the base 1 by means of sealant.

[0043] The base 1 is an insulator structure, for example, formed of one or more materials selected from ceramic, glass, silicone, plastic or rubber. The quartz crystal 2 is a rectangular parallelepiped structure, a cube structure or a cylindrical structure. A receiving groove 11 is provided in the base 1, and the shape and size of the receiving groove 11 are adapted to the shape and size of the quartz crystal 2, and the quartz crystal 2 can be effectively placed so that the quartz crystal 2 does not move in the base 1.

[0044] The first electrode 3 can be a positive electrode or a negative electrode, and the second electrode 4 can be a positive electrode or a negative electrode. The specific positive electrode or negative electrode of the first electrode 3 and the second electrode 4 is set according to actual needs.

[0045] The sealant includes one of a wet air vulcanized sealant, a chemical vulcanized sealant, a silicone sealant, a polyurethane sealant, or a polysulfide sealant.

[0046] Wet air vulcanizing sealants: This type of sealant uses moisture in the air to vulcanize, including single-component polyurethane, silicone rubber and polysulfide rubber, etc. Their polymer base contains active genes that react with water in the air to form cross-linking bonds, causing the sealant to vulcanize into a network structure.

[0047] Chemically vulcanized sealants: This type of sealant includes two-component polyurethane, silicone rubber, polysulfide rubber, chloroprene rubber and epoxy resin sealants. They are generally vulcanized at room temperature. Some single-component chlorosulfonated polyethylene and chloroprene rubber sealants and polyvinyl chloride sol paste sealants, such as automotive spot welding glue, must be vulcanized by chemical reaction under heating conditions.

[0048] Silicone sealant: widely used in construction and industrial fields, can withstand high temperatures, harden at room temperature, and has high crack resistance and waterproof properties. Silicone sealant can also be used for packaging electronic components, but is not suitable for use in environments that require organic solvents and grease.

[0049] Polyurethane sealant: It has high compression and impact resistance and can recover elastically after heating. Therefore, polyurethane sealant is very suitable for use in a variety of high-load environments.

[0050] Polysulfide sealant: Liquid polysulfide rubber is used as the main agent, and reinforcing agents, toughening agents, tackifiers, thixotropic agents and other additives are added to make a base paste. The two components can be cured into an elastic sealing material after mixing. Polysulfide rubber has excellent resistance to fuel, hydraulic oil, water and various chemicals, as well as heat resistance and atmospheric aging resistance, good softness and insulation properties, and good adhesion to most materials.

[0051] Other types of sealants include acrylic sealants, anaerobic sealants, epoxy sealants, butyl sealants, neoprene sealants, PVC sealants and asphalt sealants.

[0052] In this way, a quartz crystal packaging structure is provided by the coordinated arrangement of the base 1, the quartz crystal 2, the first electrode 3, the second electrode 4, and the sealant. The quartz crystal 2 is placed in the receiving groove 11 in the base 1, and the two connecting terminals 21 of the quartz crystal 2 are electrically connected to the first electrode 3 and the second electrode 4, so that the sealant seals the opening of the base 1. Because the sealant is a fluid structure, there is no gap between the base 1 sealed by the sealant 5 and the outside, which can achieve a better sealing effect. At the same time, the waterproof effect of the quartz crystal packaging structure is better.

[0053] In one embodiment, the open end of the base 1 has a two-step structure 12, which is used to make the sealant 5 be at the same level as the open end of the base 1 when sealing. The two-step structure 12 forms a accommodating groove for the sealant 5, so that the sealant 5 is first placed on the two-step structure 12, and then flows into the accommodating groove 11 through the two-step structure 12, thereby sealing the quartz crystal 2 in the base 1. At the same time, the setting of the two-step structure 12 makes the sealant 5 be at the same level as the open end of the base 1 when sealing, making the packaging structure of the quartz crystal look more beautiful.

[0054] In one embodiment, the receiving groove 11 has a separator 111 for separating the first electrode 3 and the second electrode 4. Thus, by providing the separator 111, the first electrode 3 and the second electrode 4 can be effectively separated to avoid a short circuit caused by the connection between the first electrode 3 and the second electrode 4, thereby preventing the quartz crystal 2 from being damaged.

[0055] In one embodiment, the bottom surface of the receiving groove 11 is a curved surface or a curved surface structure. Thus, the bottom surface of the receiving groove 11 is a curved surface or a curved surface structure, which can facilitate the placement of the quartz crystal 2.

[0056] In one embodiment, the bottom of the base 1 has a first mounting portion 13 for mounting the first electrode 3. Thus, the shape of the first mounting portion 13 is adapted to the shape of at least a portion of the first electrode 3, so that at least a portion of the first electrode 3 is tightly attached to the bottom of the base 1, and a first through hole is provided at a position of the bottom of the base 1 adapted to the first mounting portion 13, so that another portion of the first electrode 3 passes through the first through hole into the containing groove 11 and is electrically connected to one of the wiring terminals 21 of the quartz crystal 2.

[0057] In one embodiment, the bottom of the base 1 has a second mounting portion 14 for mounting the second electrode 4. Thus, the shape of the second mounting portion 14 matches the shape of at least a portion of the second electrode 4, so that at least a portion of the second electrode 4 fits tightly against the bottom of the base 1, and a second through hole is provided at a position of the bottom of the base 1 that matches the second mounting portion 14, so that another portion of the second electrode 4 passes through the second through hole into the containing groove 11 and is electrically connected to another terminal 21 of the quartz crystal 2.

[0058] In one embodiment, the second mounting portion 14 is provided with a first notch 141. Thus, when the second electrode 4 needs to be removed, the first notch 141 can be provided so that a finger can enter the first notch 141 to take out the second electrode 4.

[0059] A packaging method for a quartz crystal packaging structure,

[0060] A receiving groove 11 is formed on the base 1 ; the quartz crystal 2 is adapted to the shape and size of the receiving groove 11 .

[0063] The quartz crystal 2 is packaged in the base 1 by means of sealant.

[0064] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
