Description

Technical Field

[0001] This utility model relates to the field of low-frequency crystal resonators, and in particular to a low-frequency crystal resonator. Background Technology

[0002] A low-frequency crystal resonator is an electronic component that can generate stable oscillation signals in the low-frequency range. It typically operates between tens of kilohertz and several megahertz. It utilizes the piezoelectric effect of crystals. When an electric field is applied to the two ends of the crystal, mechanical vibration is generated. Conversely, mechanical vibration also generates an electric field, thus forming a stable oscillation. It has advantages such as high frequency stability, high precision, and low power consumption. It is widely used in electronic clocks, computer clock circuits, communication equipment, and other fields to provide these devices with accurate clock signals and stable frequency references. It is one of the key components to ensure the normal operation of electronic equipment and accurate timekeeping.

[0003] However, the pins of low-frequency crystal resonators are prone to bending during transportation, mainly because their pins are usually made of metal, which has a certain degree of toughness and is relatively thin. Under the action of external forces such as bumps, squeezing, and collisions during transportation, they are difficult to withstand large external impacts. In addition, the packaging protection measures are insufficient, and no special packaging materials or cushioning structures are used, making it difficult to effectively disperse external forces. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the leads of low-frequency crystal resonators are easily bent during transportation, mainly because the lead material is usually metal, which has a certain toughness and is relatively thin. Under the action of external forces such as bumps, squeezing and collisions during transportation, it is difficult to withstand large external impacts. In addition, the packaging protection measures are insufficient, and no special packaging materials or cushioning structures are used, making it difficult to effectively disperse external forces. Therefore, a low-frequency crystal resonator is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a low-frequency crystal resonator, comprising a crystal body and a protective device. Pins are fixedly mounted on the lower surface of the crystal body. The protective device is disposed on the lower surface of the crystal body. The protective device includes a plastic sleeve, which is fitted onto the pins. There are four plastic sleeves arranged symmetrically. A frame is fixedly connected to the surface of each plastic sleeve, and the frame is fixedly connected to each of the four plastic sleeves. A groove is formed on the surface of the frame, and a push rod is slidably connected to the inner wall of the groove. A rod body is fixedly connected to one side of the push rod. A hole is formed on one side of the crystal body, and the rod body is inserted into the crystal body. By setting up the protective device, reliable physical protection can be provided for the pins of the low-frequency crystal resonator, reducing the bending and deformation of the pins due to external collisions and squeezing during transportation, ensuring that the pins maintain their original shape and structure, and guaranteeing the smooth progress of subsequent installation and welding as well as the stability of electrical connection performance.

[0006] Preferably, a fixing plate is fixedly connected to one side of the push rod. The fixing plate is L-shaped and slidably connected to the frame. By setting the push rod, when the plastic sleeve is put on the pin and the pull block is released, the originally restrained push rod begins to slide due to the elastic force generated by the spring. During the movement, the push rod drives the rod body to insert into the crystal body. In this way, the plastic sleeve is firmly fixed on the pin, thereby realizing the protection function of the pin.

[0007] Preferably, a partition is fixedly connected to the side of the frame near the fixed plate, and a pull block is fixedly connected to the surface of the fixed plate.

[0008] Preferably, a spring is fixedly connected to one side of the partition, and the end of the spring away from the partition is fixedly connected to the fixing plate. By setting the spring, during transportation, the elastic force generated by the spring squeezes the fixing plate, and the fixing plate drives the push rod to slide, so that the rod is inserted into the crystal body, thereby firmly putting the plastic sleeve on the pin, preventing the plastic sleeve from falling off, providing reliable protection for the pin, and avoiding the pin from bending due to external forces such as collision and squeezing during transportation.

[0009] Preferably, buffer components are provided on both sides of the crystal body. The buffer components include columns that are slidably connected to the crystal body. A rubber pad is fixedly connected to one end of the column. By providing buffer components, the force between the crystal body and the circuit board can be effectively buffered when the crystal body is installed on the circuit board. The elastic deformation of the rubber pad and the sponge strip absorbs the pressure, reduces wear between the two, reduces mechanical damage caused by the installation process, and improves the installation quality and service life of the crystal resonator.

[0010] Preferably, a sponge strip is fixedly connected to one end of the crystal body near the rubber pad, and the sponge strip is located between the rubber pad and the crystal body.

[0011] Preferably, the sponge strip contacts the rubber pad, and there are two rubber pads arranged symmetrically. By setting the sponge strip, the pressure transmitted from the rubber pad is borne during the installation of the crystal body, further reducing the pressure between the crystal body and the circuit board, thereby playing a buffering role and reducing wear between the two.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a protective device, the plastic sleeve is placed on the pin during transportation. Then, the pull block is released, the push rod is unrestrained, and the spring generates elastic force to squeeze the fixing plate. The fixing plate is forced to slide the push rod. During the movement of the push rod, the rod body is inserted into the crystal body. At this time, the plastic sleeve is fixed on the pin and protects the pin. By setting a protective device, reliable physical protection can be provided for the pin of the low-frequency crystal resonator, reducing the bending and deformation of the pin due to external collisions and squeezing during transportation. This ensures that the pin maintains its original shape and structure, and provides a guarantee for the smooth progress of subsequent installation and welding and the stability of electrical connection performance.

[0014] 2. In this utility model, by setting a buffer component, when the crystal body is installed, it is in contact with the circuit board. The rubber pad first abuts against the circuit board and slides under force. Then, it squeezes the sponge strip. The sponge strip bears the pressure and reduces the pressure between the crystal body and the circuit board, thus reducing wear. By setting a buffer component, when the crystal body is installed on the circuit board, the force between the crystal body and the circuit board can be effectively buffered. The elastic deformation of the rubber pad and the sponge strip absorbs the pressure, reducing wear between the two, reducing mechanical damage caused by the installation process, and improving the installation quality and service life of the crystal resonator.

[0022] Please see Figures 1-6 This utility model provides a technical solution: a low-frequency crystal resonator, including a crystal body 1 and a protective device 3. Pins 2 are fixedly installed on the lower surface of the crystal body 1, and the protective device 3 is disposed on the lower surface of the crystal body 1.

[0023] In this implementation scheme: the protective device 3 includes a plastic sleeve 31, which is fitted onto the pin 2. There are four plastic sleeves 31 arranged symmetrically. A frame 32 is fixedly connected to the surface of the plastic sleeve 31. The frame 32 is fixedly connected to each of the four plastic sleeves 31. A groove is opened on the surface of the frame 32. A push rod 33 is slidably connected to the inner wall of the groove on the surface of the frame 32. A rod body 34 is fixedly connected to one side of the push rod 33. A hole is opened on one side of the crystal body 1. The rod body 34 is inserted into the crystal body 1. By setting the protective device 3, reliable physical protection can be provided for the pin 2 of the low-frequency crystal resonator, reducing the bending and deformation of the pin 2 due to external collisions and squeezing during transportation, ensuring that the pin 2 maintains its original shape and structure, and providing a guarantee for the smooth progress of subsequent installation and welding and the stability of electrical connection performance.

[0024] Specifically, a fixing plate 35 is fixedly connected to one side of the push rod 33. The fixing plate 35 is L-shaped and is slidably connected to the frame 32. By setting the push rod 33, after the plastic sleeve 31 is put on the pin 2, the pull block 36 is released. The push rod 33, which was originally restrained, begins to slide due to the elastic force generated by the spring 37 pushing the fixing plate 35. During the movement, the push rod 33 drives the rod body 34 to insert into the crystal body 1. In this way, the plastic sleeve 31 is firmly fixed on the pin 2, thereby realizing the protection function of the pin 2.

[0025] Specifically, a partition 38 is fixedly connected to the side of the frame 32 near the fixed plate 35, and a pull block 36 is fixedly connected to the surface of the fixed plate 35.

[0026] Specifically, a spring 37 is fixedly connected to one side of the partition 38. The end of the spring 37 away from the partition 38 is fixedly connected to the fixing plate 35. By setting the spring 37, during transportation, the elastic force generated by the spring 37 squeezes the fixing plate 35. The fixing plate 35 drives the push rod 33 to slide, so that the rod 34 is inserted into the crystal body 1, thereby firmly putting the plastic sleeve 31 on the pin 2, preventing the plastic sleeve 31 from falling off, providing reliable protection for the pin 2, and avoiding the pin 2 from bending due to external forces such as collision and squeezing during transportation.

[0027] Specifically, buffer components 39 are provided on both sides of the crystal body 1. The buffer components 39 include a column 393, which is slidably connected to the crystal body 1. A rubber pad 391 is fixedly connected to one end of the column 393.

[0028] In this embodiment: by setting the buffer component 39, when the crystal body 1 is installed on the circuit board, the force between the crystal body 1 and the circuit board can be effectively buffered. The elastic deformation of the rubber pad 391 and the sponge strip 392 absorbs the pressure, reduces the wear between the two, reduces the mechanical damage caused by the installation process, and improves the installation quality and service life of the crystal resonator.

[0029] Specifically, a sponge strip 392 is fixedly connected to one end of the crystal body 1 near the rubber pad 391, and the sponge strip 392 is located between the rubber pad 391 and the crystal body 1.

[0030] Specifically, the sponge strip 392 contacts the rubber pad 391, and there are two rubber pads 391 arranged symmetrically.

[0031] In this embodiment: by setting a sponge strip 392, the sponge strip bears the pressure transmitted from the rubber pad 391 when the crystal body 1 is installed, thereby further reducing the pressure between the crystal body 1 and the circuit board, thus playing a buffering role and reducing wear between the two.

[0032] Working principle: By setting up the protective device 3, during transportation, the plastic sleeve 31 is fitted onto the pin 2, and then the pull block 36 is released, the push rod 33 is unrestrained, and the spring 37 generates elastic force to squeeze the fixing plate 35. The fixing plate 35 is forced to slide the push rod 33. During the movement of the push rod 33, the rod body 34 is inserted into the crystal body 1. At this time, the plastic sleeve 31 is fixed on the pin 2 and protects the pin 2. By setting up the protective device 3, reliable physical protection can be provided for the pin 2 of the low frequency crystal resonator, reducing the bending and deformation of the pin 2 due to external collisions and squeezing during transportation, ensuring that the pin 2 maintains its original shape and structure, and providing a guarantee for the smooth progress of subsequent installation and welding and the stability of electrical connection performance.

[0033] By setting the buffer component 39, when the crystal body 1 is installed, it is in contact with the circuit board. The rubber pad 391 first abuts against the circuit board and slides under force. Then, it squeezes the sponge strip 392. The sponge strip 392 bears the pressure and reduces the pressure between the crystal body 1 and the circuit board, thus reducing wear. By setting the buffer component 39, the force between the crystal body 1 and the circuit board can be effectively buffered when the crystal body 1 is installed on the circuit board. The elastic deformation of the rubber pad 391 and the sponge strip 392 absorbs the pressure, reduces the wear between the two, reduces mechanical damage caused by the installation process, and improves the installation quality and service life of the crystal resonator.
