Description

Low-frequency crystal resonator Technical Field The utility model relates to the technical field of low-frequency crystal resonators, in particular to a low-frequency crystal resonator. Background The low-frequency crystal resonator is an electronic element capable of generating stable oscillation signals in a low frequency band, generally has a working frequency of tens of kilohertz to several megahertz, utilizes the piezoelectric effect of a crystal, generates mechanical vibration when an electric field is applied to two ends of the crystal, and generates an electric field when the mechanical vibration is applied to two ends of the crystal, so that stable oscillation is formed. However, the pins of the low-frequency crystal resonator are flexible in the transportation process, mainly because the pins are made of metal generally, have certain toughness and are relatively slender, and are difficult to bear large external impact under the external force actions of transportation jolt, extrusion, collision and the like, and the packaging protection measures are insufficient, so that the special packaging materials or buffer structures are not adopted, and the external force is difficult to be effectively dispersed. Disclosure of utility model The utility model aims to solve the problems that pins of a low-frequency crystal resonator are easy to bend in the transportation process, and the pins are generally made of metal, have certain toughness and are relatively fine, so that the low-frequency crystal resonator is difficult to bear larger external impact under the external force actions of transportation jolt, extrusion, collision and the like, and the packaging protection measures are insufficient, and the special packaging material or buffer structure is not adopted, so that the external force is difficult to effectively disperse. In order to achieve the purpose, the low-frequency crystal resonator comprises a crystal body and a protection device, wherein pins are fixedly arranged on the lower surface of the crystal body, the protection device is arranged on the lower surface of the crystal body and comprises plastic sleeves, the plastic sleeves are sleeved with the pins, the four plastic sleeves are symmetrically arranged, the surface of each plastic sleeve is fixedly connected with a frame, the frames are respectively and fixedly connected with the four plastic sleeves, the surface of each frame is provided with a sliding groove, the inner wall of each sliding groove on the surface of each frame is in sliding connection with a push rod, one side of each push rod is fixedly connected with a rod body, one side of each crystal body is provided with a hole, the rod body is inserted with the crystal body, and by arranging the protection device, the pins of the low-frequency crystal resonator can be reliably protected physically, bending deformation of the pins due to external force collision and extrusion in the transportation process is reduced, the pins are ensured to maintain the original shape and structure, and the stability of electric connection performance are ensured.
